Hello, I am attempting to use NRPE to monitor services on a seperate network. I have it set up and it seems to work. [from the nagios server]: bash-2.05$ ./libexec/check_nrpe -H <a href="http://1.1.3.5">1.1.3.5</a> -c check_load OK - load average: 2.01, 1.88, 1.41 [entry from nrpe.conf from the nrpe server]: command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10 My issue is trying to have the nrpe server check a different box that is within the same nework. [entry from nrpe.conf from the nrpe server]: command[check_db_listener]=/usr/local/nagios/libexec/check_oracle2 1 db01 [running the command manually on the nrpe server as user nagios]: -bash-3.00$ /usr/local/nagios/libexec/check_oracle2 1 db01 OK - reply time HOST = <a href="http://1.1.1.11">1.1.1.11</a> from db01 [running the command from the nagios server]: bash-2.05$ ./libexec/check_nrpe -H <a href="http://1.1.3.5">1.1.3.5</a> -c check_db_listener CHECK_NRPE: Socket timeout after 10 seconds. ..Any ideas? Thanks in advance.
