[CentOS] APC Smart-ups status codes (slightly OT)
We got replacement battery kits for some of our APC UPS' (Smart-UPS, rackmount). I put them into one tray (it's for an RBC 43, which takes 8, and weighs a ton), and put it in, and let it charge. Idiot change battery led stays on. So I hit the test button, it discharges very rapidly (a good number of servers on this), and the led stays on. For some reason, apcupsd's USB test fails, with an HIDDEV i/o error. So I got rid of the weird APC usb cable, and put in one of their serial cables, and run the smart test (the USB does more), and get results showing everything's fine. But the idiot light's still on. So, looking at all the values that the apcsmart choice can give me, the first thing is UPS status. I've been googling for a while, and can't find a single reference to it.

In fact this is exactly the condition I wanted to capture as unavailability window FWIW, I am approaching this with tcpdump tcpdump -s 0 -A -i eth0 -n -q - '(dst host mumble and dst port 80) and tcp[13] == 2' Basically checking for the SYN flag in the outgoing traffic. But it is generating too much data for my purposes. Another approach I have in mind is running a proxy and logging the outgoing connection -- will that be resource hungry?

IOW, Two programs Firefox and squid proxy running every such box : Centos Desktops running in GUI mode. Will 512MB RAM be sufficient to what you are suggesting? I have over 300 such desktops distributed across the geographical having a unpredictable connectivity and each one of them just use one browser based on-line application and some cron scripts for monitoring and logging simple details. Changing the h/w configuration is nearly impossible now.. or is there another lightweight solution?

If you merely erased the file with a rm command or something like that, you can probably just download the glibc-devel rpm from your friendly neighbourhood Centos mirror site, extract libc.a from it and copy it back into /usr/lib. Or you could download the glibc-devel rpm and use the rpm command with the --replacepkgs directive to reinstall the whole rpm. Either method should work. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
