Monitoring and ICMP

Hi all,

 

 

hopefully a quick question with an easy answer!. I have two nodes [i.e Two windows 2003 server] which were monitored using the icmp health monitor [This is monitoring the box itself and not the webserver on it]. However, our security team is not happy with it and have asked that we enable the Windows Firewall on that machine and thus turn off icmp traffic.

 

 

Now i was trying another health monitor [tcp echo] but with the Windows 2003 Firewall activated the Health Monitor is marking the member has down. So the question is: on which port the tcp echo operates in order for me to enable this port on the window firewall?

 

 

Thank is advance.

    The echo service runs on TCP port 7, but there needs to be an echo server running there for the monitor to succeed. Telnet to your server on port 7 and see if you get a connection. If you do, see if input you provide is echoed back to the screen. If it is, you should be in business.
