FAQ Database : Addons : NRPE

Title:Could not read request from client, bailing out
FAQ ID:F0438
Submitted By:Axel Thirud 
Last Updated:12/15/2009

Description:You are unable to check the remote daemon with check_nrpe even though you can check locally and connect to the tcp port with a telnet session. The client times out. On the daemon server you see these messages in /var/log/messages when running nrpe with debug=1 in nrpe.cfg: "Could not read request from client, bailing out"  

Solution:The nrpe deamon has been built with no ssl support and the client is trying to use ssl. Use check_nrpe -n to run the check without ssl or recompile the nrpe daemon with ssl support. 

Keywords:nrpe, ssl
