SNMP Error During OMSA 5.x Installation on SUSE 9/10
Posted by Planet Malaysia on March 22, 2008
As per our early How To Install/Uninstall OMSA In SLES9 or SLES10 guide, I found a SNMP error during OMSA 5.x installation on SLES 9 and SLES 10.
In /var/log/net-snmpd.log
[smux_accept] accepted fd 9 from 127.0.0.1:64126 refused smux peer: oid SNMPv2-SMI::enterprises.674.10892.1, descr Systems Management SNMP MIB Plug-in Manager
[smux_accept] accepted fd 9 from 127.0.0.1:64130 refused smux peer: oid SNMPv2-SMI::enterprises.674.10892.1, descr Systems Management SNMP MIB Plug-in Manager
In /var/log/messages
kernel: snmpd[17957]: segfault at 0000000000000001 rip 00002b69d10f7c10 rsp 00007fffdae1a3c8 error 4.
kernel: snmpd[17957]: segfault at 0000000000000001 rip 00002b69d10f7c10 rsp 00007fffdae1a3c8 error 4.
What is SMUX?
SMUX is the snmp multiplexing protocol (RFC 1227). It can be used by an
snmp agent to query variables maintained by another user-level process.
How does it work?
Assuming ‘snmpd’ is already up and running, when the SMUX peer comes up,
it identifies itself with an oid identifier and string password, and
registers any MIBs it would like to implement. When ‘snmpd’ receives
queries for these MIBs, it passes these queries to the peer.
For any reason OMSA expects a password when connecting smux. Again, I have experience that SLES 9 used to be worked without password.
1. edit snmpd.conf
Add:
trapsink <ipaddress of ITA Box/Monitoring Server> public
replace:
smuxpeer .1.3.6.1.4.1.674.10892.1
with:
smuxpeer .1.3.6.1.4.1.674.10892.1 <password>
2. set password OSMA
cd /opt/dell/srvadmin/dataeng/bin/
./dcecfg32 command=setsmuxpassword password=<password>
3. restart OMSA
srvadmin-services.sh restart
4. restart SNMPD
/etc/init.d/snmpd restart
5. snmp running OK now.
tail -f /var/log/messages
tail -f /var/log/net-snmpd.log
Updated: worked fine without password on OMSA 5.4(Linux) released few days back.
Hope this can help! Enjoy!
