About check_udp plugin

[Yu Watanabe]

Hello All,

I would like to get an advice with check_udp plugin.

I would like to check the snmp port (161) of the remote host.
Following is the command that I have executed from the command line.

[root at GWkensyo libexec]# ./check_udp -V
check_udp v1729 (nagios-plugins 1.4.10)

But the result looks not good.

[root at GWkensyo libexec]# ./check_udp -v -H 192.168.225.85 -p 161 -s "04 06 70 75 62 6c 69 63 a1 19 02 04 40 64 18 b9 
02 01 00 02 01 00 3
0 0b 30 09 06 05 2b 06 01 02 01 05 00" -e ""
Using service UDP
Port: 161
flags: 0x2
Send string: 04 06 70 75 62 6c 69 63 a1 19 02 04 40 64 18 b9 02 01 00 02 01 00 30 0b 30 09 06 05 2b 06 01 02 01 05 00
server_expect_count: 1
        0:
CRITICAL - Socket timeout after 10 seconds

I have tried to send get request to the remote server to fetch the data of
.1.3.6.1.2.1. but there wasn't any response. 

The data was successfully fetched using the snmpwalk command. And 
also, I have confirmed that the port was open on the remote machine.

[root at essen tmp]# netstat -an | grep 161
udp        0      0 0.0.0.0:161                 0.0.0.0:*
unix  3      [ ]         STREAM     CONNECTED     28103161 /var/lib/mysql/mysql.sock
unix  3      [ ]         STREAM     CONNECTED     28099161 /var/lib/mysql/mysql.sock

How does everyone generally specify the arguments of the check_udp
to confirm the 161 port ?

Any help will be helpful !

Best Regards,
Yu Watanabe
