Thanks Joel for quick response.
We can get snmp-get response = 1 only in case of timeout or there are any other
scenarios where we can get it as "1" ?

Hi Akshay,
I'm not part of the dev team, but I can give an educated guess as to why it
behaves like that.
As you know, the Unix convention for return status is that if the command exits
normally, it should return 0. It should only return some other number if the
command failed to execute as expected, and in other words the output will not
be complete.
In the case of the timeout, that's a failure to reach the Agent (for whatever
reason), and thus the command is not delivering the requested data to the user.
So it exits with status 1, to indicate that it failed to provide the requested
information.
The other failure you posted (No Such Object), however, is a different story.
Here, there was a response from the Agent, where the Agent is saying that the
requested OID is not available in its MIB view. The snmpget command prints the
response and exits, which is considered normal operation.
So, I think there is a certain logic to it. If there is a response, print the
response and exit with status 0. If there is no response, for some reason, exit
with error status. It doesn't consider what the content of the response is.
If you need to find out if an error was returned from the Agent, then you'll
have to parse the printed output.
Best regards,
Joel Hansell

Hello,
I would like to know the response of snmp get in case of failure. We are
getting zero in most of the success cases.
If we can get 1 in case of timeout, shall we use value of "$?" as snmp success
and failure (0 and 1 respectively) on Solaris box ? please reply asap. Thanks
