CHECK_NRPE: Socket timeout

[Gary Danko]

I have two machines that are running nagios, mon0 and discostu. mon0
is able to check services via NRPE but discostu is not. Both machines
can telnet to port 5666 on the target.

root at discostu:/usr/lib/nagios/plugins# telnet 172.16.4.24 5666
Trying 172.16.4.24...
Connected to 172.16.4.24.
Escape character is '^]'.
^]
telnet> quit

root at discostu:/usr/lib/nagios/plugins# ./check_nrpe -H 172.16.4.24  -c
check_sda1 -a 60 50
CHECK_NRPE: Socket timeout after 10 seconds.

Meanwhile, on mon0...

root at mon0:/usr/lib/nagios/plugins# telnet 172.16.4.24 5666
Trying 172.16.4.24...
Connected to 172.16.4.24.
Escape character is '^]'.
^]
telnet> quit

root at mon0:/usr/lib/nagios/plugins# ./check_nrpe -H 172.16.4.24 -c
check_sda1 -a 60 50
DISK OK - free space: / 8749 MB (51%);| /=8329MB;17018;17028;0;17078

In 172.16.4.24's syslog I am seeing this when discostu tries to grab somne info.

Jul 12 14:41:53 admin nrpe[18445]: Could not read request from client,
bailing out...
Jul 12 14:41:53 admin nrpe[18447]: Could not read request from client,
bailing out..

Both mon0 and Discostu are Debian 3.1. Both are using NRPE 2.0. This
makes no sense to me. Thanks in advance! :)
