Accessing Ubuntu desktop from Mac Snow Leopard

Posted on by

Accessing my Ubuntu 9.04 Gnome desktop from the built in Mac OS X 10.6.2 VNC viewer took a bit of tweaking on the Ubuntu Gnome side. I have an OpenVPN SSL tunnel between the Mac and the Ubuntu desktop, however a SSH tunnel could also be used to protect the VNC session. In this post, I’ll just cover the VNC server setup assuming a secure connection between the Mac and the desktop.

Initially I followed the guidance at sanity, inc.”How to OS X Leopard Screen Sharing with Linux“, on Ubuntu I installed tightvnc:

apt-get install tightvncserver

Then tested it out by starting up the vnc server on the Ubuntu system as the user I want to run the remote session as:

tightvncserver -geometry 1024x700 -depth 24 :1

As tightvncserver starts up the VNC service, it will check for a .vncpasswd file in the user home directory. If it doesn’t exist, you will be prompted for a password to use to protect the remote session.  Note VNC is not designed to be used for multi-user remote access.
On the Mac, rather than use Bonjour to automatically discover the Ubuntu screen sharing service, I just referred to the VNC session directly within Finder which invokes the built in VNC viewer. Enter the VNC session password when prompted and the Ubuntu desktop is displayed. connect-to-server Within Finder, either use Go -> Connect to Server or Apple-K to bring up the Connect to Server window.  The server address is the URL that points to the Ubuntu VNC instance vnc://10.10.1.2:5901 where the port is 5900 + the display number specified when starting up the tightvncserver (5901).

This all worked fantastic, except for the keyboard mapping within Gnome – it was scrambled.  After googling several possible solutions, the only one that was successful for me was to disable the keyboard plugin in Gnome

I’ve also encountered this issue with TightVNC and the hardy release. My solution was to capture the xmodmap -pke output as ${HOME}/.Xmodmap at the login screen (DISPLAY=:0 XAUTHORITY=/var/lib/gdm/:0.Xauth sudo xmodmap -pke > ${HOME}/.Xmodmap). When gnome-settings-daemon starts up and finds an .Xmodmap, it asks if it should be loaded — I answer yes. As a side effect, if gnome-settings-daemon were to be restarted without the .Xmodmap, it’d scramble the keyboard layout again. With an .Xmodmap in place, it’ll load the .Xmodmap every time.

Due to another issue (#199245, gnome-settings-daemon crashing with BadWindow every time a window is mapped), I disabled the keyboard plugin using gconf-editor, at /apps/gnome_settings_daemon/plugins/keyboard. Since it’s not being loaded, I suspect it might not garble the layout even if I remove the .Xmodmap now.

So maybe disabling the keyboard plugin is a better fix.

On the Ubuntu system, invoke the Gnome configuration editor (gconf-editor on command line), then navigate to apps -> gnome_settings_daemon -> plugins -> keyboard uncheck the Active keyword.  Kill the VNC daemon and relaunch it – problem fixed.

pkill vnc
tightvncserver -geometry 1024x700 -depth 24 :1

Various methods exist to automatically start and kill the VNC server, but for now this will do it for me.

IMAP mailstore migration .. again

Posted on by

So last weekend, I discovered that Spamhaus decided it would be a good idea to place all of the public IP addresses for Slicehost (my Linux VPS hoster) into their Spamhaus block list (SBL). This covered both my slice in Dallas and the one in St. Louis – meaning an impressive chunk of inbound mail to my domains was being trashed by the sending MTA and an even bigger chunk of my outbound mail was being outright rejected since the sending IP’s were on the SBL.  Slicehost worked hard to convince Spamhaus to recind the blocklist, so the Slicehost IP’s got moved over to the less-nasty-but-you’re-still-probably-a-spamming-dirtbag Policy Block list (PBL) assuming affected IP owners would request to be removed from that list.

Sample query to see if you’re on any Spamhaus block list:  http://www.spamhaus.org/query/bl?ip=10.11.12.13

It seems it’s time to relinquish the care and feeding of my own Postfix mail system and turn to a hosted solution.  This means I need to migrate about 5GB of IMAP store to another site (again).  Last time I did a wholesale migration, I used imapsync to make the transition painless. In the code example below, an SSL connection to the IMAPS server at imap-server.sourcedomain.com is made with username@sourcedomain.com and the password stored in the plaintext file secret1. An SSL connection is made to the target system (which happens to be the server on which the imapsync tool is running, but could just as easily be another IMAPS server somewhere on a network accessible to the host where imapsync is running). The –delete and –expunge1 arguments will clean the successfully moved messages from IMAP store #1 .. so be sure you have your messages on the target successfully! Imapsync can be run iteratively to ensure you have got all the messages from your source.


/usr/bin/imapsync \
--host1 imap-server.sourcedomain.com \
--ssl1 \
--authmech1 LOGIN \
--user1 username@sourcedomain.com --passfile1 secret1 \
--host2 127.0.0.1 --user2 username@targetdomain.com --passfile2 secret2 \
--ssl2 \
--delete --expunge1 \
--buffersize=128

And one can use the

--dry

option to just test the process but not actually move any of the messages.

So that’s it – I’m about half way though migrating my current IMAP stores over to a hosted mail solution, so that I don’t need to keep up with the increasing level of care and feeding that running your own mail service requires.  Before I get too many darts about that .. I first started running my own personal MTA in 1995, adding spam and av filtering over time, and adding substantial redundancy (servers, sites, storage) so I could rely on it and fix things that broke as I had time rather than right when they broke (which was always at a bad time).  My new hosted solution takes over from two VPS servers running Postfix, Spamassassin, ClamAV, Greylisting with the IMAP store replicated across data centers in different states (15 minute rsyncs).  So soon, the (hopefully) last Allen Pomeroy owned and operated MTA can be turned off, while I get to work on fun stuff, rather than figuring out why my email is bouncing.  🙂

Update 2012/12/17:

Sometimes manual manipulation of your mailstore via IMAP is needed, so here’s how I deleted a large number of folders I had trashed and were being synced to my new system from the old.  Kinda clunky, since I didn’t get the scripted version to work (just used a copy/paste in an interactive bash session), but got the job done for now.

Connect to the IMAP server using SSL:
openssl s_client -crlf -connect imap.emailsrvr.com:993

* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Server ready director6.mail.ord1a.rsapps.net

Log in with your email credentials:
0 login user@domain.com Password

0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS QUOTA] Logged in

List the folders you want to remove:
0 list "" "Trash.*"

That didn’t return the list I was expecting, so I listed all folders
0 list "" "*"

… and realized the source mail system adds “INBOX” on the front of the folder names, so then this command worked to list the folders to be deleted:
0 list "" "INBOX.Trash.*"

I copied the output and edited it to insert the folder name into a delete command:
0 delete "INBOX.Trash.Folder1"
0 delete "INBOX.Trash.Folder2"
0 delete "INBOX.Trash.Folder3"

0 OK Delete completed.
0 OK Delete completed.
0 OK Delete completed.

Finish off the session by logging out:
0 logout

* BYE Logging out
0 OK Logout completed.

Building a web security lab (with VMware Fusion)

Posted on by

Problem: VMware machines load boot loader immediately, no BIOS banner, so can’t get into BIOS to alter boot settings.
Solution: Edit the vm’s .vmx file and add the line:

bios.bootDelay = "5000"

which adds a 5000 millisecond (5 second) delay to the boot, or add:

bios.forceSetupOnce = "TRUE"

to make the VM enter the BIOS setup at the next boot.

Problem: VMware Fusion 3.0 doesn’t give a way to edit the virtual network settings via the GUI.
Solution: To change the subnet used by the NAT or HostOnly networks, go root in Mac OS X and edit

/Library/Application Support/VMware Fusion/networking

and set the following lines to the subnets desired:

answer VNET_1_HOSTONLY_SUBNET 192.168.35.0
answer VNET_8_HOSTONLY_SUBNET 10.10.1.0

To add additional custom isolated host only VLANs, also edit the networking file and add additional VNET definitions. There can apparently only be 8 VLANs with VLAN 1 and 8 already pre-defined.

answer VNET_2_DHCP no
answer VNET_2_HOSTONLY_NETMASK 255.255.255.0
answer VNET_2_HOSTONLY_SUBNET 10.10.21.0
answer VNET_2_VIRTUAL_ADAPTER yes
answer VNET_3_DHCP no
answer VNET_3_HOSTONLY_NETMASK 255.255.255.0
answer VNET_3_HOSTONLY_SUBNET 10.10.22.0
answer VNET_3_VIRTUAL_ADAPTER yes
answer VNET_4_DHCP no
answer VNET_4_HOSTONLY_NETMASK 255.255.255.0
answer VNET_4_HOSTONLY_SUBNET 10.10.23.0
answer VNET_4_VIRTUAL_ADAPTER yes

Now create your vm with as many network interfaces as you have separate VLANs (vnet) then edit the node.vmx vm configuration file and change the interfacename.connectionType to custom, and define the VLAN (vnet) that interface will attach to:

#ethernet0.connectionType = "nat"
ethernet0.connectionType = "custom"
ethernet0.vnet = "vmnet3"

Also realize that VMware will take the .1 host address on each vmnet – so you cannot assign .1 to any of your VMs.

Problem: Ubuntu 9.10 persistent network configuration (stores the MAC address of network adapters), so if you copy a machine, by default Ubuntu will setup a new logical adapter (eth1) since the MAC address has changed (when you answer I Copied It in VMware).
Solution: Tell VMware you copied the machine, so it will chose a unique MAC address. Boot Ubuntu into single user mode (another article on that to follow) then edit the MAC address associated with eth0.

sudo vi /etc/udev/rules.d/70-persistent-net.rules

find the stanza of the network interface in question (NAME=”eth0″) and set the following ATTR tag to the new MAC address:

ATTR{address}=="new-mac-address-here"

Sifting through Checkpoint FW1 logs

Posted on by

Recently I found myself in the unhappy position of needing to sift through slightly more than a billion Checkpoint Firewall-1 log lines, looking for specific patterns of access. The problem was that many of the exported fwm log files had differing column positions and there had been many ruleset changes over the course of 11 months worth of log data. Many of the excellent FW1 log summarization tools (such as Peter Sundstrom’s fwlogsum) didn’t handle the hundreds of files and differing column positions.

The final scripted solution was processing over 11,000 lines/second .. and still took over 23 hours for the first run.

Log file exports via fwm logexport can have variable column positioning, except for record ID number “num”, which is *always* column number one.  I see three viable alternatives to the changing column position in the ASCII log files exported via fwm – so we can automate the log processing:

  • Export the FW1 log file to ASCII via
    fwm logexport -i fw1-binary-logfile -o fw1-ascii-logfile.txt -n -p
    1. Parse the header line (line #1) of every log file and dynamically map (rearrange) the columns to a pre-determined standard in memory before further processing (painful, expensive)
    2. Tell Checkpoint fwm to export in a fixed column ordering
        create
        logexport.ini
        and place in
        $FWDIR/conf directory
        eg. fwmgmtsrv:
        C:\WINDOWS\FW1\R65\FW1\conf
        logexport.ini:
        [Fields_Info]
        included_fields = num,date,time,orig,origin_id,type,action,alert,i/f_name,
        i/f_dir,product,rule,src,dst,proto,service,s_port,xlatesrc,xlatedst,
        nat_rulenum,nat_addtnl_rulenum,xlatesport,xlatedport,user,
        partner,community,session_id,ipv6_src,ipv6_dst,
        srckeyid,dstkeyid,CookieI,CookieR,msgid,elapsed,
        bytes,packets,start_time,snid,ua_snid,d_name,id_src,ua_operation,
        sso_type_desc,app_name,auth_domain,uname4domain,wa_headers,
        result_desc,r_dest,comment,url,redirect_url,enc_desc,e2e_enc_desc,
        auth_result,attack,log_sys_message,
        rule_uid,rule_name,service_id,resource,reason,cat_server,
        dstname,SOAP Method,category,ICMP,message_info,
        TCP flags,rpc_prog,Total logs,
        Suppressed logs,DCE-RPC Interface UUID,Packet info,
        message,ip_id,ip_len,ip_offset,fragments_dropped,during_sec
    3. Use OPSEC LEA tools to extract event log records instead of export via fwm logexport

    Once the ASCII log files are available for processing, my fw1logsearch.pl script can be used to find complex patterns of interest.  Any matching records found by fw1logsearch will be output with an initial FW1 header line so that fw1logsearch can be used iteratively, to build very complex search criteria.  fw1logsearch can also write out a discard file allowing completely negative logic searches resulting in 100% of the input data separated into a match file and a didn’t match file.  Some examples of how I’ve used it are shown here:

    gunzip -c fwlogs/2009*gz | \
    fw1logsearch.pl --allinclude \
    -S '10\.1\.1[1359]\.|10\.2\.1[01]\.|192\.168\.2[245]\.' \
    -d '10\.1\.1[1359]\.|10\.2\.1[01]\.|192\.168\.2[245]\.' \
    -p '^1310$|^1411$|^1812$|^455' | \
    fw1logsearch.pl -S '192\.168\.22\.14$|10\.2\.11\.12$' |\
    fw1logsearch.pl --allexclude \
    -S '^192\.168\.24\.12$' -P '^1310$' --rejectfile 192-168-24-12-port-1310.txt

    Line by line:
    1. Unzip the compressed ASCII log files, feed them to the first instance of fw1logsearch.pl
    2. First fw1logsearch – all conditions must be true for any events to match
    Source address must NOT be in any of the following regex ranges:
    10.1.11.* 10.1.13.* 10.1.15.* 10.1.19.*
    10.2.10.* 10.2.11.*
    192.168.22.* 192.168.24.* 192.168.25.*
    Destination address must be in one of the same following regex ranges.
    Service (destination port) must be one of:
    Exactly port: 1310, 1411, 1812, or any port starting with 455
    No protocol is specified, so it will match either TCP or UDP

    fw1logsearch.pl will output any matching events to stdout, including a FW1 log header line, so the next instance of fw1logsearch.pl continues filtering the result set.

    3. The second fw1logsearch.pl specifies Source Address must not be any of the following
    192.168.22.14

    10.2.11.12

    4. The last fw1logsearch.pl excludes port 1310 from 192.168.24.12, and puts all those records into a separate reject file, while writing the other records to stdout.

    This script has been used to process over 4 billion records within the project I wrote it for – and precisely found all the use of particular business cases I needed to modify.  The result was zero outages and no unintended business interruption.

    Basic syntax/help file:

    Usage:  fw1logsearch.pl
    [-a|–incaction|-A|–excaction <action regex>]
    [-p|–incservice|-P|–excservice <dst port regex>]
    [-b|–incs_port|-B|–excs_port <src port regex>]
    [-s|–incsrc|-S|–excsrc <src regex>]
    [-d|–incdst|-D|–excdst <dst regex>]
    [-o|–incorig|-O|–excorig <fw regex>]
    [-r|–incrule|-R|–excrule <rule-number regex>]
    [-t|–incproto|-T|–excproto <proto regex>]

    [–dnscache <dns-cache-file>]
    [–resolveip]
    [–allinclude]
    [–allexclude]
    [–rejectfile <file>]
    [–debug <level>]

    fw1logsearch.pl will search a fwm logexport text file for regex patterns specified for supported columns (such as service, src, dst, rule, action, proto and orig).

    Include and exclude regex matches may be specified on the same line, although they both will include (print) a line or exclude (reject) a line based on single matches.  Allinclude or Allexclude must be specified to force a match
    only on all specified column regex patterns.

    Regex patterns can be enclosed with single quotes to include characters that are special to the shell, such as the ‘or’ (|) operator.

    Header will be output only if there are any matching lines.

    Example invocations:
    $ cat 2008-07-07*txt | \
    fw1logsearch.pl \
    -p ’53|domain’ \
    -d ‘192.168.1.2|host1|10.10.1.2|host2’ \
    -o ‘192.168.2.3|10.10.2.4|10.10.4.5’ \
    -S ‘64.65.66.67|32.33.34.35|10.10.*|192.168.*’ \
    –resolveip
    Will require destination port (service) to be 53, destination IP to be any of 192.168.1.2, host1, 10.10.1.2, or host2  the reporting firewall (origin) to be any of 192.168.2.3, 10.10.2.4, or 10.10.4.5  and the source IP must not be
    any of 64.65.66.67, 32.33.34.35, 10.10.*, or 192.168.*  Any lines that match this criteria, will display and the orig, src, and dst columns will use the default DNS cache file (dynamically built/managed) to perform name resolution, replacing the IP addresses where possible.

    Include regex patterns:
    -a  –incaction    Rule action (accept, deny)
    -b  –incs_port    Source port (s_port)
    -p  –incservice   Destination port (service)
    -s  –incsrc       Source IP|hostname
    -d  –incdst       Destination IP|hostname
    -o  –incorig      Reporting FW IP|hostname
    -r  –incrule      Rule number that triggered entry
    -t  –incproto     Protocol of connection

    Exclude regex patterns:
    -A  –excaction    Rule action (accept, deny)
    -B  –excs_port    Source port (s_port)
    -P  –excservice   Destination port (service)
    -S  –excsrc       Source IP|hostname
    -D  –excdst       Destination IP|hostname
    -O  –excorig      Reporting FW IP|hostname
    -R  –excrule      Rule number that triggered entry
    -T  –excproto     Protocol of connection

    Other options:
    –debug {level} Turn on debugging
    –dnscache      Specify location of DNS cache file to be used with
    the Resolve IPs option
    –resolveip     Resolve IPs for orig, src, and dst columns AFTER filtering
    –rejectfile    Write out all rejected lines to a specified file

    How to build a MythTV PVR on Fedora Core 7

    Posted on by

    <Notes In Progress – many of these steps have been automated in scripts, I’m in the process of updating this doc to show those steps and include the scripts>

    Fresh install of OS and MythTV on n43

    Created 2007/09/05 – last revised 2008/01/06

    I needed to upgrade MythTV to 0.20.2 due to the demise of Zap2It schedules, but I didn’t have another system which matched the hardware used on my MythTV PVR.  So I installed a spare 120GB EIDE and started from scratch to build another MythTV instance from scratch.  Once I was satisfied the new instance would pass the SAT (spouse approval test), I used LVM to move everything over to the 320GB SATA disk which currently contains the old (production) MythTV sw and configuration.

    This describes that build and migration process. 

    Hardware (n43):

    Antec Fusion HTPC case

    antec-fusion

    AMD Sempron processor (about 1.6GHz)
    512MB memory – good enough for single tuner and OS
    Hauppage PVR-350 standard definition capture card

    Integrated on to mainboard:
    Audio:
    ALC883 PCM nVidia MCP51 controller – kernel module snd-hda-intel (high definition audio)
    Video:
    nVidia C51 – Quadro NVS 210S / GeForce 6150LE
    nVidia EIDE and SATA controller – …

    1. Install OS

    Seems to be lots of hits on Fedora 7 and MythTV, as well the reading I’ve done on Fedora 7 seems to show it can be easily kept up to date (via yum) – and it has the OS clustering capabilities as part of the base now, which I’ll use when I split the current single system making it the back end and adding a silent (diskless) front end.

    Downloaded and burnt Fedora 7 i386 DVD. For future options, extracted and burnt boot.iso … also see notes on how to install Fedora 7 via boot.iso and NFS. (notes to be added)

    Disabled SATA hdd in BIOS (could have unplugged it, but easier to just disable via sw).
    Used DVD drive in n43 to install Fedora 7 on the temporary EIDE drive.
    Select packages for install:
    MySQL Server
    Web Server

    See scripts for automated Fedora 7 OS setup and package install (setup1.shl, setup2.shl) (scripts to be added)

    About 25 min off DVD for base load

    Setup (first time boot):
    Firewall – allow SSH and HTTP, otherwise no inbound services other than ESTABLISHED,RELATED are needed at this point. Will open MySQL and ICMP for monitoring purposes later. When this system becomes the MythTV backend, will have to add MythTV ports (see FAQ).
    SELinux – disable, will add SE configuration at some future point.
    NTP – use default Fedora 7 NTP service configuration, time sync is obviously very important (unless you don’t want your recordings to start/end at the right times).

    MythTV seems to heavily use KDE, so although Gnome is default, may need to use KDE. I selected Gnome this time. And KDE this time. And RatPoison is a compact window manager which may be easier to configure for mythtv. Finally I’m using fvwm2 .. more on that later.

    Update /etc/hosts
    192.168.2.143 mythtv.networkforensics.org mythtv n43

    Manually set the interface speed/duplex (gigabit interface doesn’t do well in autonegotiate – poor performance, but no interface errors). Will come back and setup an init script.
    # ethtool -s eth0 speed 100 duplex full

    Add ATrpms repository into yum configuration:
    NOTE: other ATrpm yum configurations on the net don’t work!
    – add the following into /etc/yum.conf
    [atrpms]
    name=Fedora Core $releasever – $basearch – ATrpms
    baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable
    gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
    gpgcheck=1

    Import ATrpms key
    # rpm –import http://ATrpms.net/RPM-GPG-KEY.atrpms

    Disable ATrpms repository, so we only get mythtv packages from it:
    – add the following to the atrpms section just added to the /etc/yum.conf:
    enabled=0

    Update the packages to current using the standard Fedora repositories

     

    When following the Fedora / MythTV HOWTO (http://wilsonet.com/mythtv), they use variable KVER which is just uname -r

     

    # echo “export KVER=\\`uname -r\\`” >> /etc/profile.d/kver.sh

     

    Do yum upgrade to get latest kernel and system

    # yum upgrade

    464MB 265 packages

     

    <odd>

    Kernel panic during reboot after upgrade

    Searched on “2.6.22 fedora 7 kernel panic noapic” – lots of suggestions but doing a single boot again, while interrupting the grub boot and adding noapic to the end of the kernel boot line seemed to fix it. Now the grub.conf looks like (note the vga=791 arg):

    default=0
    timeout=5
    splashimage=(hd0,0)/grub/splash.xpm.gz
    hiddenmenu
    title Fedora (2.6.22.4-65.fc7)
    root (hd0,0)
    kernel /vmlinuz-2.6.22.4-65.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=791
    initrd /initrd-2.6.22.4-65.fc7.img
    title Fedora (2.6.21-1.3194.fc7)
    root (hd0,0)
    kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=791
    initrd /initrd-2.6.21-1.3194.fc7.img

     

    Add window manager fvwm here – comes from Fed
    ora repo

    # yum install fvwm2

     

     

    2. No mouse cursor in Gnome

    Seems the nVidia graphics are broken somehow. Must disable hardware cursor?

     

    <URL>

    ok add this line to your xorg.conf

    Option “HWCursor” “off”

    so it looks something like this

    Code:

    Section "Device"
      BoardName    "GeForce 6600/GeForce 6600 GT"
      BusID        "1:0:0"
      Driver       "nvidia"
      Identifier   "Device[0]"
      Option       "HWCursor" "off"
      Screen       0
      VendorName   "NVidia"
    EndSection

    logged out from Gnome, causes an X restart then the mouse cursor showed up properly.

     

     

    3. Set Monitor and Resolution

    In gnome, I manually set the monitor, it could not autodetect the Viewsonic Optiquest V75. Restarted X, had to set the resolution (it defaulted to way too high of a setting)

    4. Set mysql to start on boot

    chkconfig mysqld on

     

    5. Start up MySQL

    service mysqld start

     

    6. Set MySQL root password

    mysql –uroot

    mysql> grant all on *.* to root@localhost identified by “rootpassword” with grant option;

    mysql> grant all on *.* to root@n43 identified by ‘rootpassword’ with grant option;

     

    7. Create MythTV database

    Test out mysql connection, user, password

    # mysql -uroot -prootpassword

    mysql>

     

    Run MythTV database setup

    # mysql -uroot -prootpassword < /usr/share/mythtv/sql/mc.sql

    GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO mythtv@localhost
    IDENTIFIED BY “mythtv”;
    FLUSH PRIVILEGES;
    ALTER DATABASE mythconverg DEFAULT CHARACTER SET latin1;

    8. Install MythTV Suite

     

    # yum –enable=atrpms install mythtv-suite

    122 packages, 105MB

     

    Create directory for recordings

    # mkdir /storage/recordings

    # chown mythtv:mythtv /storage/recordings

     

    9.
    Install ivtv drivers and firmware for PVR-350

    # yum –enable=atrpms install ivtv-firmware
    # yum –enable=atrpms install ivtv-kmdl-$KVER

     

     

    10. Update modprobe.conf to enable TV Out on PVR-350

     

    # load ivtv-fb for PVR-350 output
    install ivtv /sbin/modprobe –ignore-install ivtv; /sbin/modprobe ivtv-fb

     

    Manually load ivtv

    # /sbin/depmod -a
    # /sbin/modprobe ivtv

     

    Manually tried to load ivtv-fb – segfaulted … see the part of the howto on modifying grub boot loader…

     

    We’re going to make little modification to the kernel boot line in your grub.conf file that should force the ivtv frame buffer to load on /dev/fb1, as well as allow the ivtv-fb module to be loaded and unloaded. Without doing this, unloading the ivtv-fb module would probably crash your system. To the end of all ‘kernel /vmlinuz…’ lines in /boot/grub/grub.conf, append ‘vga=791’, then reboot your system. This tells the kernel to load a frame buffer for your video card at 1024×768, 16-bit color. I use this all the time myself, simply so I can see more when I’m not in X. I’d always done this on my 350-equipped box without even thinking about it, which could explain some of why I’ve not run into some of the problems other folks have…

    11. Test out PVR-350 TV Out

    As per https://help.ubuntu.com/community/MythTV_Edgy_hardware_pvr-350_TV-out

     

    Try to display the TV test pattern by putting the saa7127 module into test mode:

    # /sbin/rmmod saa7127
    # /sbin/modprobe saa7127 test_image=1

     

    Works!

    Resume normal operation:

    # rmmod saa7127
    # modprobe saa7127

     

     

    Test video capture

    # /usr/bin/v4l2-ctl -i 0

     

     

    12. Manually compile ivtv module for X

    Had to manually compile ivtv driver for x to enable tv out .. due to some 2.6.22 issue.

     

    As per README in ivtv x driver package – must install xorg sdk to allow compile:

    # yum install xorg-x11-server-sdk

     

    Then compile the new ivtv xdriver:

    # sh ./configure

    # make

    # make install

     

    Copy into xorg directory:

    # cp /usr/local/lib/xorg/modules/drivers/ivtv_drv.so /usr/lib/xorg/modules/drivers

    if gdm failed, ps -ef , then kill it to restart

     

    copy in new xorg.conf (with TV Out section) and do <ctrl><alt><backspace> to restart x server

    [root@mythtv ~]# cat /etc/X11/xorg.conf.tvout

    13. Run mythtv-setup

     

    Blank menu ..

    Check out http://www.gossamer-threads.com/lists/mythtv/users/286856

    I found this simple set of directions to add in a base set of true

    type fonts (which includes Ariel) to Fedora 7 and it solved the problem.

     

    1. Open a Terminal and cd to a directory you can work in

    2. Become root

    3. Download the MS Core Fonts Smart Package File

    wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec

    4. Make sure that the rpm-build and cabextract packages are installed

    yum install rpm-build cabextract

    5. Build the Core Fonts package:

    rpmbuild -ba msttcorefonts-2.0-1.spec

    6. Install the Core Fonts package

    rpm -Uvh /usr/src/redhat/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm

     

    The web site I found this one was: http://www.fedorafaq.org/#installfonts

     

    Sign in as mythtv

    $ mythtv-setup

     

    Setup Video Capture cards, listing source, channel setup

     

    $ mythfilldatabase

     

    Setup remote control

    Go get the LIRC packages from ATrpms

    # yum –enable=atrpms install lirc-0.8.3

     

    And get the kernel modules:

    # yum –enable=atrpms install lirc-kmdl-2.6.22.4-65.fc7-0.8.3-70_cvs20070827.fc7

    resulted in:

    Installed: lirc-kmdl-2.6.22.4-65.fc7.i686 0:0.8.3-70_cvs20070827.fc7

    Dependency Installed: lirc-devices.noarch 0:0.8-4.fc7

     

    Manual test:

    # modprobe lirc_mceusb2

     

    Update modprobe.conf to load LIRC

    …

     

     

    /dev/lirc was symlinked to /dev/lirc/0 (which is the PVR-350 …) so re-linked to /dev/lirc/1 and restarted lircd

    # service lircd restart

    then irw showed button presses!

    Updated /etc/init.d/lircd to relink the /dev/lirc symlink to /dev/lirc/1

     

     

     

    Get MythTV to use remote:

    Copy lircrc file into ~mythtv/.mythtv/lircrc and ~mythtv/lircrc (no dots)

     

     

    Install lirc kernel modules

    NO yum –enable atrpms install lirc-kmdl-2.6.22.4-65.fc7

    Had to uninstall all the modules I installed then re-install lirc 0.8.3 from atrpms

    Tried ratpoison, Gnome and KDE – ratpoison I couldn’t get working without troubleshooting and Gnome and KDE are too heavy weight. fvwm works well, although the font sizes are a bit small – haven’t found where to adjust them yet.

     

    Use fvwm window manager:

     

    Add to inittab:

    c7:12345:respawn:/sbin/mingetty --autologin=mythtv tty7

    if [ -z "$DISPLAY" ] && [ $(tty) == /dev/tty7 ]; then
    while [ 1 == 1 ]
         do
              startx
              sleep 10
         done
    fi

     

     

     

    HOLD

     

    Use ratpoison window manager:

    Had to setup desktop for mythtv (all black, no screen saver)

     

     

    Migrate from 120GB disk back to 320GB SATA

    2007/10/20 Fedora 7

    Use LVM to move the data, including /root, swap and /storage

     

    In BIOS, enable SATA drive, position as HDD #2 (120GB IDE as HDD #1)

     

    Boot single user (interrupt grub, select first kernel <e>dit, select kernel spec line, <e>dit, add “single” on the end of the line, <b>oot the system (off the old IDE disk)

     

    Display partition table for both drives just to be sure that the 320GB (new) disk is /dev/sbd and the current ‘production’ IDE disk is /dev/sda

    # fdisk -l /dev/sda

    # fdisk -l /dev/sdb

     

    Zero out the partition table and MBR on the SATA disk as we had previously installed Fedora 7, and that data will confuse the migration process.

    # dd if=/dev/zero of=/dev/sdb bs=1024k count=100

     

    Partition new disk to add similar partition structure, including LVM partition

    sdb1 100MB ext3 /boot (0x83)

    sdb2 <the rest> LVM (0x8e)

     

    Set the disk bootable (option a)

     

    [root@mythtv ~]# fdisk -l /dev/sdb

     

    Disk /dev/sdb: 250.0 GB, 250059350016 bytes

    255 heads, 63 sectors/track, 30401 cylinders

    Units = cylinders of 16065 * 512 = 8225280 bytes

     

    Device Boot Start End Blocks Id System

    /dev/sdb1 * 1 13 104391 83 Linux

    /dev/sdb2 14 30401 244091610 8e Linux LVM

     

    Zero out the LVM partition as we had already setup a fresh Fedora 7 install, and the LVM information will still be there (and called VolGroup00, it will confuse LVM on the old IDE disk)

    # dd if=/dev/zero of=/dev/sdb2 bs=1024k count=100

     

    Copy the /boot contents across:

    # mkfs.ext3 /dev/sdb1

    # mkdir /tmp/new

    # mount /dev/sdb1 /tmp/new

    # cd /boot

    # find . –print | cpio –pmd /tmp/new

     

    Now update (install) boot loader on new 320GB disk:

    # mount /dev/sdb1 /tmp/new (if not still mounted)

    # mv /tmp/new/grub/device.map /tmp/new/grub/device.map.old

    # /sbin/grub-install /dev/sdb

    # umount /tmp/new

     

    Label this filesystem as /boot to match /etc/fstab:

    # e2label /dev/sdb1 /boot

     

    Now ‘create’ the new physical volume in LVM and display the pv’s to ensure all’s good:

    # pvcreate /dev/sdb2
    # pvdisplay

     

    Add the new physical volume into the VolGroup00 volume group

    # vgextend VolGroup00 /dev/sdb2

     

    Move all the physical extents from the old IDE disk to the new SATA disk (this will tell lvm to move the physical extents from PV /dev/sda2 to some other free physical volume – the only other volume is the SATA disk we just added). Note this will take a LONG time and will display it’s progress:

    # pvmove /dev/sda2

     

    Remove the old disk:

    # pvremove /dev/sda2

     

    Power off and disconnect power to the old IDE disk, boot to ensure all comes up ok

     

    Power off and remove IDE

     

    HOLD Get firmware for Hauppauge PVR-350

    RAM based filesystems in Linux

    Posted on by

    When doing I/O intensive processing on Linux systems, I’ve found that creating a RAM based filesystem can substantially improve processing times. Of course nothing but the transitory processing data should be written to the fake filesystem to avoid data loss in the case of unintended dismount or system crash.

    mount -t ramfs ramfs /tmp/ramfs -o size=4m

    Soekris net5501 SBC Linux installation

    Posted on by

    Soekris Engineering net5501 SBC setup with Linux

    2008/09/03

    net5501 is a x86 SBC that I ordered with 4 10/100 ethernet ports, 512MB memory, 500MHz Geode LX CPU

    Serial console is used for setup of net5501 – BIOS writes to serial port since there is no xVGA port. <ctrl-p> to enter BIOS setup. DB9 pinout:

    2 — 3

    3 — 2

    5 — 5

    Use 19,200 bps 8 data bits, no parity, 1 stop

    With the Macbook Pro, I use a Keyspan USA-19HS USB <–> DB9 RS232 serial converter (and DB9-RJ45 adapters to implement the null modem configuration and allow me to use an ethernet cable for the serial console <–> Keyspan device.

    On OS X (10.5) I use “screen” to provide the serial terminal interface:

    $ screen /dev/tty.USA19H1a2P1.1 19200,8

    <ctrl-a><ctrl-\> to exit

    On the net5501 BIOS, PXEBoot is disabled:

    set PXEBoot=Disabled

    I setup voyage-0.5.0 on a compact flash card then installed the card into the net5501 – works great the first boot

    Default root info: root / voyage

    MythTV FC7 LVM on RAID1 Configuration

    Posted on by

    MythTV PVR HDD Mirroring 2008/07/24
    Host: n43 (mythtv)
    – Two SATA 500GB drives sda sdb
    – current production drive is sdb

    Problem: I’ve done migrations of LVM2 volumes from 320GB SATA to 500GB SATA and added
    a redundant 500GB SATA. Now I want to get software RAID 1 setup to protect the
    root, swap and /storage filesystems from damage if/when one of the shiny new 500GB SATA
    disks bite the dust.

    Followed howtoforge.com linux_lvm_p1 (start of article) to free up sda from LVM
    volume group VolGroup00 .. http://www.howtoforge.com/linux_lvm_p7

    0. Did a file level backup to the fileserver:
    [root@n59 20080724]# sshroot@192.168.1.2This e-mail address is being protected from spambots, you need JavaScript enabled to view it“tar cf – /lib” | dd of=mythtv-lib.tar
    (repeat for /boot /storage /var /etc /home)

    1. Free up sda2 LVM volume. I know this volume is not used anymore,
    but it still has same-disk backup of /storage from when I was tweaking
    MythTV.

    [root@mythtv ~]# pvmove /dev/sda2
    [root@mythtv ~]# vgreduce /dev/VolGroup00 /dev/sda2
    [root@mythtv ~]# pvremove /dev/sda2

    – now running on sdb only –

    Setup RAID 1 mirroring (md)
    —
    2. Partition sda for mirroring (Auto RAID label)
    [root@mythtv ~]# fdisk /dev/sda
    <delete partitions>
    <add primary 1 whole disk>
    <set flag to fd – Auto RAID>

    [root@mythtv ~]# fdisk -l

    Disk /dev/sda: 500.1 GB, 500107862016 bytes
    255 heads, 63 sectors/track, 60801 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot Start End Blocks Id System
    /dev/sda1 * 1 19 152586 83 Linux
    /dev/sda2 20 60801 488231415 fd Linux raid autodetect

    Disk /dev/sdb: 500.1 GB, 500107862016 bytes
    255 heads, 63 sectors/track, 60801 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot Start End Blocks Id System
    /dev/sdb1 * 1 19 152586 83 Linux
    /dev/sdb2 20 60801 488231415 8e Linux LVM

    Notice that sdb is still using only LVM, not RAID.

    Linux iptables notes

    Posted on by

    Add local redirection of low port to unpriv high port

    Remove any existing entries:

    iptables -t nat -D PREROUTING –src 0/0 -p tcp –dport 25 -j REDIRECT –to-ports 11025 2> /dev/null
    iptables -t nat -D PREROUTING –src 0/0 -p tcp –dport 80 -j REDIRECT –to-ports 8080 2> /dev/null

    Add new redirects:
    iptables -t nat -I PREROUTING –src 0/0 -p tcp –dport 25 -j REDIRECT –to-ports 11025
    iptables -t nat -I PREROUTING –src 0/0 -p tcp –dport 80 -j REDIRECT –to-ports 8080
