Depends how you want to monitor the Unix servers. You could do this by using a SSH connection where you'd use port 22 (by default) or if you use the NRPE daemon on the target Unix server you'd use port 5666 (by default). <div class="gmail_quote">On Wed, Aug 18, 2010 at 10:31 AM, <<a href="mailto:ravishankar.gundlapali@wipro.com">ravishankar.gundlapali@wipro.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div link="blue" vlink="purple" lang="EN-US"> <div> Hi , I wanted to monitor few Unix servers also.
