Hi,

I am trying to run the snmptrapd to capture and log any traps sent to my machine.
When I run it using this command:
snmptrapd -o /home/herry/test.log

Everytime I sent the trap to my machine I get the following lline on the test.log file:
2003-11-13 14:53:21 ECServer [127.0.0.1] (via 127.0.0.1) TRAP, SNMP v1, community public UCD-SNMP-MIB::ucdExperimental.990 Enterprise Specific Trap (17) Uptime: 1:44:44.99

So the snmptrapd logs it fine, however when I try to format the log messages to something simpler and run the snmptrapd with the following command:
snmptrapd -o /home/herry/test.log -F "%02.2h:%02.2j"

I don't get nothing at all on my test.log file.

I know that the formatting was correct since if I run the snmptrapd using only the following command:
snmptrapd -P -F "%02.2h:%02.2j"

which makes the snmptrapd printing out the formatted message to stderr (which is the terminal), I get the correct format (which happen only to print out the time the trap was received).

What I don't understand is why it doesn't seem to be able to send the formatted log to the file. Am I missing something here ?

Any one can help ?

I am using RH 9 based linux and snmp software from RPM version 5.0.6-17. ( I installed both the net-snmp and net-snmp-utils rpm)

Thanks a bunch

Try a more recent version (5.1.1). If it still doesn't work, report a bug at
http://www.net-snmp.org/bugs/

Can you please share the snmptrapd.conf file here with me?

You need to start you're own thread for you're own question.

I did that but I have not got any replies ye at that thread

You need to give members time to respond and not hijack someone else's thread.

oh ok its called hijacking didn't know that

snmptrapd -tLf /your-log-location/yourlogfile.log

Restarted snmptrapd.

This worked on RHEL 6.8
net-snmp-5.5-57.el6
