net-snmp change default port 161 to something else

  • 772

Ports 161/162 are in use by a java software, so the requirement is to use 163 for net-snmp

[root@testSRV snmp]# netstat -apn | grep 162
udp        0      0 ::ffff:10.145.1.10:162    :::*                                    2827/java           
[root@testSRV snmp]# netstat -apn | grep 161
udp        0      0 ::ffff:10.145.1.10:161    :::*                                    2827/java

Trying to bring snmpd up

[root@testSRV snmp]# /etc/init.d/snmpd restart
Stopping snmpd:                                            [FAILED]
Starting snmpd:                                            [FAILED]

on /var/log/messages

Sep 17 15:55:12 testSRV snmpd[18911]: Error opening specified endpoint "udp:127.0.0.1:163"
Sep 17 15:55:12 testSRV snmpd[18911]: Server Exiting with code 1

If I remove the line "agentaddress udp:127.0.0.1:163" from /etc/snmp/snmpd.conf and use the following command

[root@testSRV snmp]# snmpd -f -Lo udp:163 -C -c /etc/snmp/snmpd.conf
error on subcontainer 'ia_addr' insert (-1)
NET-SNMP version 5.5
error on subcontainer 'ia_addr' insert (-1)
error on subcontainer 'ia_addr' insert (-1)
error on subcontainer 'ia_addr' insert (-1)

SNMPD comes up but I get the message above on the console. Is there any way to use the parameters of "snmpd -f -Lo udp:163 -C -c /etc/snmp/snmpd.conf" to /etc/snmp/snmpd.conf?
