net-snmp-5.4-14.fc7 is working for me. Please specify more precisely your configuration, including: - architecture - kernel version - net-snmp version - content of /etc/snmp/ - eventually whole coredump It's hard to guess what's wrong without this information. You can also run 'snmpd -f -Lo -DALL' and attach the output (beware, it can be long). Thanks in advance
Created attachment 218361 [details] output from 'snmpd -f -Lo -DALL'
I'm running F7 x86_64 with kernel-xen-2.6.20-2936.fc7 and net-snmp-5.4-14.fc7 [root@srv1 ~]# ls -l /etc/snmp/ total 24 -rw-rw-r-- 1 root root 700 2007-10-06 13:05 snmpd.conf -rw-r--r-- 1 root root 18628 2007-07-31 22:46 snmpd.conf.original [root@srv1 ~]# cat /etc/snmp/snmpd.conf ########################################################################### # # snmpd.conf # # - created by the snmpconf configuration program # ########################################################################### # SECTION: Access Control Setup # # This section defines who is allowed to talk to your running # snmp agent. # rocommunity: a SNMPv1/SNMPv2c read-only access community name # arguments: community [default|hostname|network/bits] [oid] rocommunity public localhost rocommunity public 192.168.88.10 rocommunity public 127.0.0.1 rocommunity public srv1 # Allow Systems Management Data Engine SNMP to connect to snmpd using SMUX smuxpeer .1.3.6.1.4.1.674.10892.1
When i comment out smuxpeer, snmpd is starting and working. I'm running F7 on a Dell PE2950.
thanks, that's I need to know. As you indicated, the problem is in the 'smuxpeer' in the snmpd.conf. You must specify a password: smuxpeer .1.3.6.1.4.1.674.10892.1 my_password I'll try to fix it to display some meaningful message instead of segfault...
I backported fix from net-snmp-5.4.1 to Fedora7, update will be available in testing repository soon.
net-snmp-5.4-15.fc7 has been pushed to the Fedora 7 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update net-snmp'
I tested those rpm's and now smuxpeer accepts no passwords and doesn't segfault. Works for me!
net-snmp-5.4-15.fc7 has been pushed to the Fedora 7 stable repository. If problems still persist, please make note of it in this bug report.
