hi,
I'm a student of Computer Science and I'm working to a project involving the
net-snmp tools. In particular I need the snmptrapd daemon to load a program
(some snmp get requests, and other things) when a particular trap is
received. I encountered the âbroken pipeâ error during my tests. I thought I
committed an error somewhere and to be sure I copied the example provided on
the toolkit-5 but the error remain.
Here is what I did.
1) snmptrapd -f -Le -D -c /usr/local/share/snmp/snmptrapd.conf
2) snmptrap -v1 -c andrea localhost 1.3.6.1.3.1.8.1 localhost 3 1 i
the snmptrapd.conf file only contains the line âtraphandle default /bin/pwdâ
I tried also to specify the 1.3.6.1.3.1.8.1 oid but nothing has changed.
Instead of /bin/pwd I initially used a bash script, the function of which was
to send a snmpget request.
I know snmptrapd passes arguments to the standard input of the called program
and maybe the problem could be found here.
I attached some log files to help you.
Please can you suggest me what to do?
Best regards
Andrea Muz
