<html> <head> <style> .hmmessage P { margin:0px; padding:0px } body.hmmessage { FONT-SIZE: 10pt; FONT-FAMILY:Tahoma } </style> </head> <body class='hmmessage'> I had some issues getting the nrpe client to run some checks properly in Solaris 10. It was the 'unable to read plugin output' error when running 'check_oracle' and some others that output multi-line text. In the end I was unable to figure out whether it was *nix permissions, RBAC, build/lib issues, an old shell, env vars, or some other subtle issue. I'm not certain, but there may be pre-compiled binaries available for Solaris 8. Anyway, good luck. Grant Lowe wrote: > Hi Philip, > > First, thanks for the reply.
