Probably one has to enable tcpwrappeer support and compile nrpe from the source.

Hello,

Seems NRPEv4 provided by EPEL distibution doesn''t support TCP wrapper. Does one need to compile it from source to have it supported or TCP wrapper is not required anymore since "allowed_hosts" option exists by default now?

Please advise,
Thanks

Hello, Do nrpe and check_nrpe do encryption by default without certs? I understand encryption with certificates adds most secure layer.

Thanks

Hello,

The binary and the conf file is supposed to owned by "root". Is that correct?

I understand the binary should be run as non-root user.

Thanks

Ok since I wanted to make use the TCP wrapper, I had hosts updated in the /etc/hosts.allow. I also had the "allowed_hosts" setting which was making NRPE to look as a first option. Per readme in the cfg it is supposed to ignore this setting but it wasn't. After commenting out the setting, i...
