Samba 3 and apostrophes in computer description
If you have an apostrophe in XP’s Computer Description field then the computer will not be recognised as part of the samba domain despite it having joined properly.
This is in samba 3.0.2a untested in more recent versions as yet.

PCI device 1283:8212 (Integrated Technology Express, Inc.)
My friend recently got an ATA133 card with this chipset on it. The full proc/pci entry looks like:
RAID bus controller: PCI device 1283:8212 (Integrated Technology Express, Inc.) (rev 17). IRQ 10. Master Capable. No bursts. Min Gnt=8.Max Lat=8. I/O at 0xdcd8 [0xdcdf]. I/O at 0xdcd0 [0xdcd3]. I/O at 0xdcc0 [0xdcc7]. I/O at 0xdcb8 [0xdcbb]. I/O at 0xdca0 [0xdcaf].
If you want to use this under linux you need to compile in the driver as detailed under the title **IT8212F
ATA133 RAID Controller** on this page (Broken link ~~http://www.ite.com.tw/software_download/software_download2.asp~~). To compile up the driver you need to enable scsi in your kernel and link /usr/src/linux-2.4 (or linux-2.6 depending on kernel version) to wherever your linux source tree is. If you are using modules remember to modprobe both scsi and sd_mod.
You then put the created iteraid.o file into
/lib/modules/<i>kernel-version</i>/kernel/drivers/ide/pci/
making directories if you have to.

Perl timeouts
Some perl that sets a timeout value
#!/usr/bin/perl $SIG{ALRM} = sub { alarmed(); }; alarm(20); eval { check_whatever; }; alarm(0); sub check_whatever() { # stuff to do that might timeout exit 0; } sub alarmed() { # stuff to do after the alarm has gone off. exit 1; }
Thanks to Timbo for help with this…
