I have 29 servers, that are identical in packages os level everything. (RH ES4)
I have nagios monitoring them using NRPE. 28 of them work.
I get connection refused on 1 server (tried xinetd and stand alone)
I run check_nrpe manually I get good results.
[root libexec]# ./check_nrpe -H bpid-02 -c check_disk1
DISK OK - free space: / 500 MB (34%);| /=974MB;1454;1464;0;1474
 CURRENT SERVICE STATE: bpid-02.budco.com;Check /;CRITICAL;HARD;4;Connection refused by host
Any help would be appreciated.
