RE: [CentOS] Reading SNMP on other machine

It will respond from another machine (WinXP). What port should I open on the box trying to do the snmpwalk? --Todd -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Les Mikesell Sent: Friday, September 23, 2005 2:33 PM To: CentOS mailing list Subject: Re: [CentOS] Reading SNMP on other machine On Fri, 2005-09-23 at 09:15, Todd Reed wrote: > I'm trying to use snmpwalk to look at other machines, but I can't get > a response.

This sounds like firewalling, but the default snmpd.conf file is very restrictive. Make sure the one on the target machine allows it to respond. -- Les Mikesell lesmikesell(a)gmail.com _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

The only thing left to investigate is to see what it takes to get these NICs to do full duplex (do I want this?) to my switch (I think it's possible, have to do some reading). I configured them that way, but upon boot something in IPCop seems to set them to half duplex. ># 3 - your email address after removing the underscores doesn't match >the email address that you sent your email with. > > :O Dyslexic keyboard interface digits! "triad", not "traid" is correct result. Wasted effort anyway. I notice that the mail system puts it all at the top of the posts but for changing "@" to "at".

Reading SNMP on other machine
by Todd Reed 23 Sep '05

23 Sep '05

I'm trying to use snmpwalk to look at other machines, but I can't get a response. It keeps timing out. It can see itself, though. I haven't had this problem with other machines and I don't know what's different. Suggestions?

CENTOS 3.5 (AMD64) NFS install issue
by Dr R L Oswald 23 Sep '05

23 Sep '05

We operate a cluster of Sun Xeon IA32 servers with Centos 3.5. Nodes are installed via a host-specific kickstart script which is generated for each node from a master template. Thus all kickstart scripts are clones of the master, edited for hostname, IP address etc only. The CENTOS 3.5 ISO images are exported from a server & that remote NFS mount is also configured in the master template. This works perfectly well & a fully automated installation requiring no operator intervention results. We recently added some new Opteron nodes to give us some 64-bit capability. These of course, use a slightly different master kickstart template as they mount up a different ISO directory from the NFS server, which contains the x86_64 version of Centos 3.5. When we install these 64-bit nodes, however, we get the message: "that directory could not be mounted from the server". On hitting OK we get the usual dialogue box which displays our chosen server IP and the correct x86_64 ISO directory, if we OK that, the NFS installation proceeds unattended as normal. I think we saw a similar thing with redHat 9 NFS kickstart installations but it was quite variable. Anyone seen that with CENTOS3 or RHEL3 & got any clues ? TIA Les

DPMS or hardware
by Sam Drinkard 23 Sep '05

23 Sep '05

List, I've been bugged by the fact that the dpms function will not work on this machine, and perhaps now I have some clue as to why. Looking at the Xorg.0.log, I see where "Open APM failed (/dev/apm_bios) (No such file or directory)" which tells me perhaps this is the reason why it won't turn off the monitor. Also, this line prior to the other. `fonts.dir' not found (or not valid) in "/usr/X11R6/lib/X11/fonts/local/". That part I can maybe fix, but I have no clue what should be in the /dev/apm. The only thing that will happen is the monitor will go into screeensaver mode, or if no saver selected, it will do nothing, not even blank. What should the /dev/apm contain? Where does it pick up the info as to what should be in there, from a probe of the hardware? That said, does the fact that I'm using a custom video driver from ATI make any difference? -- Snowman

Mirrordir with CentOS 4
by dan1 23 Sep '05

23 Sep '05

Hello everybody. I have been using Mirrordir for a long time and I wanted to know if some of you have been able to use it on a CentOS 4 system. When I try to mirror something, I receive the following error: [root@box scripts]# mirrordir ./test ./test2 Segmentation fault I have downloaded the RPM from here (version 0.10.41-1) : ftp://sunsite.unc.edu/pub/Linux/system/backup/ Is there any other RPM compatible with CentOS 4 ? Any help would be much appreciated. Thanks, Daniel

Moving a Centos 3.5 instalation with software raid 1 array + LVM from a pIII to a pIV computer.
by Alexander Georgiev 23 Sep '05

23 Sep '05

Hi All, We have an old Centos 3.5 file and database server, running on a pIII computer with Intel 820 mother board. It has a software raid 1(mirror) + LVM on two IDE hard disk. I want to upgrade to a newer computer with pIV - 2.4GHz on a Intel D848PMB mother board. Should I expect any problems if I just move the array from the old machine to the new and boot there? Should I do any preparations(I know I must do a full backup), before moving the disks? Best regards! ageorgiev

Recommendation On Ping And Alert Tool
by Kennedy Clark 23 Sep '05

23 Sep '05

A bit off topic, but I keep looking for an answer to this question and coming up with nothing... so I thought I would go to the gurus. :-) Can anyone recommend a good package for pinging other devices and sending an email/alert when they go down? I'm aware of all kinds of more complex things with GUIs and a zillion other bells and whistles we aren't looking for, but we just want a simple tool (could be daemon or something run from cron) that runs every 1 - 5 minutes and alerts us when stuff disappears. Would need some basic logic like only sending one email/alert when something goes down (vs sending an email every 1-5 minutes until it comes back up). :-) We need to avoid a requirement for an X-windows GUI, but a web-GUI would probably be fine (a GUI-less command-line thing would probably be best). TIA, KC

Just wanted to add one more tool to make this threat complete. See Opmanager at http://manageengine.adventnet.com/products/opmanager/ The free edition is really nice if you have a small network to monitor. Nassri > > Try the following ..
