check_nrpe issue

[Todd Barbera]

" That you need to do what says in the readme and look in the logs on the 
remote site. In 75 cases out of 100, the nrpe host isn't configured to 
allow the client to connect to it. In about 20% of the cases one end 
supports (and tries to use) SSL while the other doesn't. In the 
remaining 5, there is a protocol mismatch (check_nrpe 2.0 being used to 
poll nrpe 1.8)."

I think perhaps I wasn't clear on what this issue was given your response.
check_nrpe does work against these two client hosts. I am able to run
check_oracle, check_load, and check_disk via check_nrpe all without
incident. When I downloaded check_log2 and check_log.pl and tried to call
them via check_nrpe, that is when I received the error. Both check_log2 and
check_log.pl work fine if I run them locally on the client so I'm not sure
why it isn't successfully passing the results using nrpe. If I turn on
debugging, all I see in my syslog are successful connection messages. I have
read the readme, FAQ's, and mailing lists prior to posting to see if I could
find an answer, but I was unable to find any information as to why this may
be the case. Both check_nrpe and nrpe are version 2.0. Both are configured
for SSL. Here's the relevant section of nrpe.cfg:

command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c
30,25,20
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 10% -c 5% -l -e
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10
-s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c
200
command[check_oracle]=/usr/local/nagios/libexec/check_oracle --login insight
command[check_log]=/usr/local/nagios/libexec/check_logs.pl -c
/usr/local/nagios/etc/log.conf
command[check_log2]=/usr/local/nagios/libexec/check_log2 -F
/oracle/app/oracle/admin/insight/bdump/alert_insight.log -
O /usr/local/nagios/tmp/alert_insight.log -q ORA-
command[check_disksuite]=/usr/local/nagios/libexec/check_disksuite

All of these can be called successfully using check_nrpe except for
check_log and check_log2. Any ideas as to why? Thanks in advance.

That you need to do what says in the readme and look in the logs on the 
remote site. In 75 cases out of 100, the nrpe host isn't configured to 
allow the client to connect to it. In about 20% of the cases one end 
supports (and tries to use) SSL while the other doesn't. In the 
remaining 5, there is a protocol mismatch (check_nrpe 2.0 being used to 
poll nrpe 1.8).

I shall have to remedy that. Thanks for pointing it out.
