Hi Dave,

I modified the community name to "public1" in com2sec as you suggested,
sent the snmpv2 request using "public1" and the request is forwarded by
SNMPD to subagent. I could access the same "table1" registered by two
subagents with two different contexts by sending different community
names in snmpv2 request.

Thanks a lot for all your help.

Regards,
Suresh.

Good.

My best guess is that these are two separate access control settings,
and the first (default context) is masking the second.

Try changing this to

   com2sec -Cn context1  user1  default   public1

and run the query using "-c public1"

> createUser user1 MD5 user123 DES

I'd also suggest that you use a *different* username
in the "com2sec" line, from your rwuser/createUser
settings.

These are all completely separate access control
settings - so re-using the same names will lead
to confusion (at best), or a broken setup.

It should do, yes.

Probably because you've got other access control stuff that's being used
instead.

Always try working with the smallest possible snmpd.conf file. Once
you've got each individual bit working, you can look at stitching it all
together.
