Hi All,
I have an issue with net-snmp communication from a monitoring server to HP UX server.
Following are the details
HP - UX server : 172.16.184.34
Monitoring Server : 172.16.5.57
(Solarwinds Application)
I'm running HP-UX's snmp on udp port 161 and net-snmp on udp 1161.
HP-UX-root-:/#>lsof -i udp:161
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
snmpdm 14986 root 6u IPv4 0xe00000038ead7080 0t0 UDP *:snmp (Idle)
HP-UX-root-:/#>lsof -i udp:1161
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
snmpd 3411 root 6u IPv4 0xe00000036a2c1680 0t0 UDP *:netsnmp (Idle)p
Following is the instance of net-snmp in the porcess tables
root 3411 1 0 May 9 ? 2:40 /opt/iexpress/net-snmp/sbin/snmpd -Lf /var/adm/snmpd.log -V -A -a -p /var/tmp/net-snmpd
I'm able to snmpwalk to localhost as well as the Monitoring server( using private community). Following is the log detail when I try to snmp walk from the monitoring server to the HP-UX server
NET-SNMP version 5.7.2

What I did not understad is the ip address in the log above. It should be a request coming from Monitoring server ( 172.16.5.57) rather than the ip of the HP-UX. Below is my routing table on HP
Routing tables
Destination Gateway Flags Refs Interface Pmtu
127.0.0.1 127.0.0.1 UH 0 lo0 32808
172.16.184.34 172.16.184.34 UH 0 lan0 32808
172.16.184.0 172.16.184.34 U 2 lan0 1500
127.0.0.0 127.0.0.1 U 0 lo0 32808
default 172.16.184.1 UG 0 lan0 1500
I'm not running HP's IP packet filter or tcp wrappers. There is not firewall between the two hosts they are participating in different VLANS.
Any hint/idea would be highly appreciated
Thanks in advance
