Re: snmpset failes with Reason: notWritable (That object does not support modification) ...Even with rwcommunity permissions

[Vipul M. <vi4...@gm...>]

Thanks Suresh,

We have to write /generate a c code even if our mib contains a simple integer.

 I followed the  link , now its snmpset and get are working for me.
http://www.net-snmp.org/wiki/index.php/TUT:Writing_a_Subagent

to create a subagent for my mib . The subagent talks to net-snmp agent over TCP

regards
Vipul
