[OM IT Services]

hi all,
im tryng to send the test trap from the SMH running on a linux box (redhat 5.5) but i've got this error:

/var/log/secure:
sudo: hpsmh : sorry, you must have a tty to run sudo ; TTY=unknown ; PWD=/opt/hp/hpsmh/data/htdocs/webagent ; USER=root ; COMMAND=/usr/bin/snmptrap -v1 -ctestsim mysimserver.com enterprises.232 6 11003 system.5.0 s linuxhostname enterprises.232.11.2.11.1 i 0 enterprises.232.11.2.8.1 s Test Trap

running the command from console:

snmptrap -v1 -c testsim mysimserver.com enterprises.232 6 11003 system.5.0 s linuxhostname enterprises.232.11.2.11.1 i 0 enterprises.232.11.2.8.1 s Test Trap

The Sim have discovered the linux machine but no events is reported.
