cactid snmp timeout 'ignoring host'

[murphy]

Hello all,

We've been having some problems with cactid(0.8.6g) reporting timeouts. Eventhough we tried upping both timeouts to 5000ms.
here is the output :

Code: Select all

CACTID: Host[13] DS[220] WARNING: SNMP timeout detected [5000 ms], ignoring host 'xxxxxxxxxxxxxxx'
CACTID: Host[13] DS[220] SNMP: v1: xxxxxxxxxxxxxxx, dsname: traffic_in, oid: .1.3.6.1.2.1.2.2.1.10.1, value: U

The interresting part is that when I start a cactid process manually (cactid -R 13 13) I can clearly see that it can not have waited the 5sec timeout because the output appears within 1 sec.

I then tried to tcpdump it to see if the packets are really sent, here is what I get :

Code: Select all

09:01:02.492030 IP yyyyyyyyyyyyyyy > xxxxxxxxxxxxxx: icmp 31: echo request seq 0

09:01:02.541844 IP xxxxxxxxxxxxxx.snmp > yyyyyyyyyyyyyyy.40810:  C=public GetResponse(33)  tooBig[errorIndex==0] interfaces.ifTable.ifEntry.ifInOctets.1= [|snmp]
09:01:02.545877 IP yyyyyyyyyyyyyyy.40810 > xxxxxxxxxxxxxx.snmp:  C=public GetRequest(30)  interfaces.ifTable.ifEntry.ifOutErrors.2
09:01:02.548657 IP xxxxxxxxxxxxxx.snmp > yyyyyyyyyyyyyyy.40810:  C=public GetResponse(31)  interfaces.ifTable.ifEntry.ifOutErrors.2=0

Which seems to show that :
-it pings and responds to pings
-it can get the uptime
but for some reason I get a tooBig[errorIndex==0] which seems like the problem.
I also tried doing a snmpget with 'interfaces.ifTable.ifEntry.ifOutErrors.2=0' and I get "IF-MIB::ifInOctets.1 = Counter32: 1784831038" and a tcpdump of such a request doesn't say "too big".

For info, net-snmp version is 5.2.1.2

Any ideas ?

P.S. as a side note is it normal that cactid reports beeing version 0.8.6f when it's actually a 0.8.6g ?
