Yes, it's backwards compatible.

I compiled and installed the version of the agent you mentioned in Nagios and the target machine but still the issue persist.I also did a restart of XINETD after installing the new agent since i am running the agent under inetd.
Let me know if I have to perform any other stpes to make it work.

Can you run the following command on both, Nagios XI server, and the client machine (remote box), and show the output?

Code: Select all

/usr/local/nagios/bin/nrpe

I tested NRPE Version: 2.16RC2, and it seemed to resolve the issue for me. I set up a simple command on the remote box:

Code: Select all

command[catafile]=cat $ARG1$

and restarted xinetd:

Code: Select all

service xinetd restart

On the Nagios XI box, I ran:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c catafile -a '/usr/local/nagios/var/nagios.log' | wc -m
22518

Note: Before recompiling NRPE, with ver. 2.15, I was getting 1024 characters.

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c catafile -a '/usr/local/nagios/var/nagios.log' | wc -m
1024

unfortunately after doing this ?upgrade all the HP UX servers running NRPE V2.0 getting Service check Time outs,is there way I can fix these errors quickly

[lmiltchev]

What are the commands that you ran while recompiling NRPE?

Can you show us the actual check (that is failing) run from the command line, along with the output of it?

Also, show us how the command is defined on the client.

Run:

Code: Select all

/usr/local/nagios/bin/nrpe | grep -i version

on both - Nagios XI and the client, and show the output.

Steps followed to install

1.unzip nrpe-nrpe-2-16-RC2.zip

Tried to install suse10 ,11 ,12 but no luck and getting the same error.

On nagios server able to install it successfully though

/usr/local/nagios/bin/nrpe | grep -i version

Can you please attempt to install the openssl-devel package and see if this helps?

[mdusanapudi]

Hi
can you please let me know the max output size that we can use with Nrpe 2.16 RC2.

According to our developers, "it's almost 64K". Thanks!
