Re: Pass through extension not working Snmpd

Thank you so much Alistair for replying. Apparently the passtest script had
a tiny bug. The case statement which checks for a particular OID has been
broken into multiple line but without any line continuation terminator '\'
and which was giving syntax error which i came to know only after i ran the
script individually. Thanks again. I wonder how a test script which was
downloaded for the net-snmp website could have such bugs? And i was silly
as i wasn't checking if the script was actually working and i was just
trying to get the value from the MIB browser!
