[Asterisk-Users] RedHat 9 & VSFTPD & Digium Hardware Oddoties
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 Feb 1 16:37:06 dunpbx last message repeated 4 times Feb 1 17:06:01 dunpbx last message repeated 2 times Feb 1 17:07:15 dunpbx last message repeated 2 times Feb 1 20:08:11 dunpbx last message repeated 2 times Feb 2 07:51:11 dunpbx last message repeated 2 times Feb 2 10:29:03 dunpbx vsftpd: warning: can't get client address: Bad file descriptor Feb 2 10:31:18 dunpbx vsftpd: warning: can't get client address: Bad file descriptor Feb 2 12:17:14 dunpbx vsftpd: warning: can't get client address: Bad file descriptor Feb 2 12:33:22 dunpbx vsftpd: warning: can't get client address: Bad file descriptor Feb 2 15:17:27 dunpbx vsftpd: warning: can't get client address: Bad file descriptor Feb 2 15:22:47 dunpbx vsftpd: warning: can't get client address: Bad file 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: Feb 3 03:16:07 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 03:16:09 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 03:16:18 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 03:16:30 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 04:14:24 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 04:14:26 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 04:14:36 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 04:14:42 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 04:14:47 NOTICE[1167272000]: Fax detected, but no fax extension Feb 3 04:14:48 WARNING[1167272000]: Detected alarm on channel 2: Red Alarm Feb 3 04:14:51 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 04:14:57 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 04:14:59 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 04:15:08 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 04:15:11 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 04:15:20 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 04:15:30 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 05:18:45 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 05:18:47 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 05:18:57 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 05:19:04 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 05:19:09 NOTICE[1167272000]: Fax detected, but no fax extension Feb 3 05:19:10 WARNING[1167272000]: Detected alarm on channel 2: Red Alarm Feb 3 05:19:13 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 05:19:18 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 05:19:22 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 05:19:29 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 05:19:33 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 05:19:40 WARNING[1133718080]: Detected alarm on channel 2: Red Alarm Feb 3 05:20:04 NOTICE[1133718080]: Alarm cleared on channel 2 Feb 3 05:20:09 WARNING[1167272000]: Detected alarm on channel 2: Red Alarm Feb 3 05:20:13 NOTICE[1133718080]: Alarm cleared on channel 2 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. Regards, Brent
