SNMP monitoring options

Hi all, Been using Cacti for monitoring various things like, system disk/mem/ proc, network usage, router usage etc... While its been fun, the graphs are just unruly. Was looking an OpsView (the free version), wondering what your experience with this type of trend/heuristic analysis has been and what what you like. And of course thoughts on OpsView. - aurf

glibc-2.5-58.el5_6.2.i686 broken?
by Leonard den Ottolander 20 Apr '11

20 Apr '11

Hi, I woke up Saturday morning unable to boot my freshly upgraded 5.6 with grub hanging at "GRUB". After getting the boot loader fixed I experienced crashes in evolution. Downgrading glibc to 2.5-58 seems to fix these issues. Anyone else seeing this? Leonard. -- mount -t life -o ro /dev/dna /genetic/research

Named, logging of requests
by Jussi Hirvi 20 Apr '11

20 Apr '11

This is not really CentOS-specific - sorry. On a name server, I would like to log ns queries (specifically, queries which result with no answer) regarding one domain (for which my ns is authoritative). Is this possible? I know you can turn on logging "globally" using the logging section of named.conf. - Jussi -- Jussi Hirvi * Green Spot Suvilahdenkatu 1 B 78 * 00500 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi(a)greenspot.fi * http://www.greenspot.fi

Cant find out MCE reason (CPU 35 BANK 8)
by Vladimir Budnev 20 Apr '11

20 Apr '11

Hello community. We are running, Centos 4.8 on SuperMicro SYS-6026T-3RF with 2xIntel Xeon E5630 and 8xKingston KVR1333D3D4R9S/4G For some time we have lots of MCE in mcelog and we cant find out the reason. "Ordinary" mce message looks like: CPU 51 BANK 8 TSC 8511e3ca77dc MISC 274d587f00006141 ADDR 807044840 STATUS cc0055000001009f MCGSTATUS 0 decode with mcelog --ascii --cpu p4(cause there is no xeon56xx in list): HARDWARE ERROR. This is *NOT* a software problem! Please contact your hardware vendor CPU 53 BANK 8 TSC 1982d8f72b1f MISC e1742eac00006242 ADDR 7ffd78a80 MCG status: MCi status: Error overflow MCi_MISC register valid MCi_ADDR register valid MCA: MEMORY CONTROLLER RD_CHANNELunspecified_ERR Transaction: Memory read error STATUS cc0002000001009f MCGSTATUS 0 The global question is it possible to find out the exact hw which causes those messages? First we thought that according to /* A machine check record */ struct mce { __u64 status; /* bank status register */ __u64 misc; /* misc register (always 0 right now) */ __u64 addr; /* address or 0 */ __u64 mcgstatus; /* global MC status register */ __u64 rip; /* Program counter or 0 for silent error */ __u64 tsc; /* cpu time stamp counter */ __u64 res1; /* for future extension */ __u64 res2; /* dito. */ __u8 cs; /* code segment */ __u8 bank; /* machine check bank */ __u8 cpu; /* cpu that raised the error */ __u8 finished; /* entry is valid */ __u32 pad; }; cpu is the cpu rised the exception, but we have 2 quadro cpus with HT so maximum cpu number should be 16 and in logs we see 53 etc. So no we r not sure about what cpu value is :)Does anyone know what the CPU number means exactly? One more interesting thins is the following output: [root@zuno]# cat /var/log/mcelog |grep CPU|sort|awk '{print $2}'|uniq 32 33 34 35 50 51 52 53 Those numbers are always the same. Ok.Supposed we have problem in RAM, since i dont really know what those cpu numbers mean we suppose that cpu+bank can point the problem hw.Is it possible? According to our "broken ram theory" we suppose that those numbers 32,33,34,45 and 50,51,52,53 indicate some simetric problem with ram/or slots or smth else.Is it correct? Thanks in advance.

Can anyone post a working pppd config?
by johhny_at_poland77 20 Apr '11

20 Apr '11

I just need a "temporary" pppoe server, that only uses PAP ___Can someone post a howto, just in a few lines, what to do?___ If I just do "pppd require-pap" then it gives this error: pppd: The remote system is required to authenticate itself pppd: but I couldn't fin any suitable secret (password) for it to use to do so. pppd is by default installed. and there are just a few modifications needed to start it with only using PAP auth.. what am I missing? It's not needed, that the clients actually log in through pppoe, I just need a pppoe server that enforces PAP, so that we could get the passwords of the clients... Thank you in anticipation..!!

cross-platform email client
by Florin Andrei 20 Apr '11

20 Apr '11

I'm a Thunderbird user almost since day one, but now I'm looking for something else. For whatever reason, it doesn't work well for me - every once in a while it becomes non-responsive (UI completely frozen for several seconds, CPU usage goes to 100%) and I just can't afford to waste time waiting for the email software to start working again. My main desktop platform is Linux, but I need a client that works the same and looks the same on Windows too. Email server is IMAP with a pretty hefty account: over a hundred folders, hundreds of thousands of messages total (server-side filtering with Sieve). Typically it's a remote session, over VPN. So the client better work well, and be glitch-free. The issues with Thunderbird might be related to the size of my IMAP account, plus the VPN latency - but frankly, I don't care, the client needs to hide all that stuff from me, do the updates or whatever in the background, instead of blocking the UI until it's done. Ironically, it blocked when I was done with this paragraph and I hit Enter. Sticking it to the man one last time, I guess. Any suggestions? Thanks. -- Florin Andrei http://florin.myip.org/

Dear all, i've appended the below to /etc/bashrc it works like a charm with ssh connections though SFTP sessions fail since the below is being sent to the intiator. any way of limiting the below to none sftp sessions? or any other idea for it to work? # If id command returns zero, you’ve root access. if [ $(id -u) -eq 0 ]; then # you are root, set red colour prompt echo "###############################################" echo "### You are now working as ROOT. ###" echo "### Pay attention to what you type. ###" echo "###############################################" PS1="\\[$(tput setaf 1)\\]\\u@\\h:\\w #\\[$(tput sgr0)\\]" else # normal echo echo " ###########################################################" echo "Welcome $(whoami), here's something to start your day with:" echo echo `sh /etc/lines.sh /etc/quotes.txt` echo " ############################################################" echo PS1="[\\u@\\h:\\w] $" fi Thanks, --Roland

by Eric Kaufmann 19 Apr '11

19 Apr '11

I can't get java applets to run in Firefox. We are using centos 5.3, firefox 3.0.11. Java version 1.6.0_24 is installed. java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode) I know there has been allot written about this issue. I did look and there is no jre plug in installed for Firefox. I tried to reinstall java and this did not work either. Any ideas?
