The only issues I am seeing are some snmp timeout errors in
MailScanner-mrtg.
Scott,
Did you manage to figure out an answer for this?
Not yet. I can poll snmp without error from the commandline, but get
timeouts
almost every run of mailscanner-mrtg.
I am about ready to disable the snmp tests in mrtg until I can figure
it out.
I am getting tired of having my servers nag me all day.
Since you asked, are you seeing the same thing?
Yup, ever since servers upgraded to 4.5.. something like:
Timeout: No Response from localhost:161
.
Works as expected from the command line though.
Further troubleshooting:
mailscanner-mrtg uses this to query the interfaces
/usr/bin/snmpwalk -v 2c -c COMMUNITY localhost:161 .1.3.6.1.2.1.2.2.1.16
This was timing out but would strangely not show on it on the terminal
when run manually. This surely wasn't the case before.. so a 'rpm -q
--changelog net-snmp-utils | head -13' tells me that now 'communication
can be limited by tcp_wrappers'. Adding the right entry to hosts.allow
appears to have solved the problem.
