I went ahead and installed libssl0.9.8

I have doubled checked and read some various help posts and it seems that it is the equivalent for Ubuntu.

Went back and double checked a few more things:

On the client machine
root@ip-:~# /usr/local/nagios/libexec/check_nrpe -H localhost -n
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

root@ip-:~# /usr/local/nagios/libexec/check_nrpe -H xx.xx.xxx.xx
CHECK_NRPE: Socket timeout after 10 seconds.

Try:

Code: Select all

apt-get install libssl-dev

[trafalgargirl]

Yes - already did that

On the client machine, what is the output of:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H localhost

[trafalgargirl]

root@ip-xxx-xx-xx-xxx:~# /usr/local/nagios/libexec/check_nrpe -H localhost
CHECK_NRPE: Error - Could not complete SSL handshake.

I also tried

root@nagios:~# /usr/lib/nagios/plugins/check_nrpe -H xx.xx.xxx.xxx -> client IP
-bash: /usr/lib/nagios/plugins/check_nrpe: No such file or directory

Can you please run these commands on the NRPE Client and show us the output:

Code: Select all

ps -ef | grep xinetd
ps -ef | grep nrpe

[trafalgargirl]

On the nagios machine
