Hi,
I need a help from you pls... Our snmp suddenly stopped responding on linux
box and when i try to run snmpwalk command on host I'm getting "Timeout: No
Response from localhost" message. I just did strace snmpwalk and below is
the snipped output. if you can give me any clue that would be helpful to me.
Thanks in advance...
# snmpwalk -c emc-it -v 1 localhost
Timeout: No Response from localhost
#
# strace snmpwalk -c emc-it -v 1 localhost
