net-snmp issue
Hi there, We are having a very strange issue with net-snmp on Solaris 10 server. snmpd dies all of the sudden, and then we try to disable the service, it goes into maintenance mode, I have to run another disable to bring snmpd into disabled mode, then I enable it back. It runs ok for 30 sec or so, you can see on snoop that it is receiving UDP traffic from another hoist sent via snmpd, then it dies. Have you guys seen behavior like that from any other user? Also I noticed that there are 4K BOUND and 5K CLOSE_WAIT ports on netstat -an. I also heard about the MOB cache table limitation to 1000 of those. When it is working, i can snmpget to myself (same server) ecweb02 [/] # /usr/local/bin/snmpget -v 2c -c Dk2twmP$ ecweb02 sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (259458) 0:43:14.58 When it is not, it timesout: ecweb02 [/] #/usr/local/bin/snmpget -v 2c -c Dk2twmP$ ecweb02 sysUpTime.0 Timeout: No Response from ecweb02.

No, we did not compile it on our own, it came with Solaris Thanks Sergey Prilutsky From: harda...@users.sourceforge.net To: sprilut...@hotmail.com CC: harda...@users.sourceforge.net; net-snmp-coders@lists.sourceforge.net Subject: Re: Very weird net-snmp issue on Solaris 10 server Date: Thu, 18 Aug 2011 09:52:49 -0700 On Thu, 18 Aug 2011 10:07:19 -0500, Sergey Prilutsky sprilut...@hotmail.com said: SP it is not Solaris snmp, it is net-snmp Yes, but I mean did it come with the solaris OS (which redistributes our agent), or did you compile your own?

RE: Very weird net-snmp issue on Solaris 10 server
it is not Solaris snmp, it is net-snmp snmpd is online and enabled (SMF) and there are no messages. It just stops to process requests, like you saw in higlighted (red) packets. Plus when I do snmpget, it gives me timeout Does someone know about the MIB cache table and it's limitations/configuration?

Is this the snmpd that comes with solaris, or a self-built one? You might consider building a newer copy to see if that fixes the problem. SP snmpd dies all of the sudden When you say dies, is the process still around? Your note made it a bit unclear. SP When it is not, it timesout: SP ecweb02 [/] #/usr/local/bin/snmpget -v 2c -c XX ecweb02 sysUpTime.0 SP Timeout: No Response from ecweb02. Have you tried a very long timeout (try -t 60 as an option, for example).

If not, you should always be blocking SNMP at your border unless you need it to go across. And certainly you shouldn't be using community names that have been advertised publicly (and that includes using any you might have just sent to a public mailing list like this one). -- Wes Hardaker Please mail all replies to net-snmp-coders@lists.sourceforge.net -- Get a FREE DOWNLOAD! and learn more about uberSVN rich system, user administration capabilities and model configuration.
