[Asterisk-Users] RedHat 9 & VSFTPD & Digium Hardware Oddoties

[Mindworks Wireless]

Here is my experience so far to treat some issues I have been having with
Digium hardware (t100p, and x100p's.)  I am not 100% certain these are
fixxes, but just something for people to try if they are expierencing
issues with the hardware performing quirky.

1st)  Do NOT use Promise Array ATA Raid controllers in a sytem with Digium
Hardware.  This created many random red alarm issues with the X100P card,
as I would see an error generated by both Asterisk and the Array Card.

2.)  RedHat 9 with vsftpd running, set tcpwrapper=yes if you use the
Asterisk Box as a FTP boot server and the PBX.  My polycom phones would
sometime act quirky, and I would get multiple errors from vsftpd about a
bad file descriptor.  The exact error messages would be:

Feb  1 10:17:34 dunpbx vsftpd: warning: can't get client address:
Bad file descriptor
Feb  1 13:51:49 dunpbx last message repeated 2 times

descriptor
Feb  2 15:47:48 dunpbx vsftpd: warning: can't get client address: Bad file
descriptor

Setting to tcpwrapper=yes in the vsftpd.conf resolves this issue.  I
noticed that when I would see a slew of these messages, I would see random
red alarms on my PBX:

Just some things I wanted to throw out there in case anyone else runs into
something weird and this might help them.  Again, I am not one hundred
percent certain this resolves the issues above, but it certainly seems
like it has helped.
