Hi:
I am currently using the UPTIME utility as a valuable tool for all servers in my network to check uptime & availability.
However, some servers have been placed behind a firewall, and now UPTIME seems to fail - unable to connect to HOST.
Does anyone know the nature of how or what protocol/port UPTIME uses to connect to server?
What strategy would have to be used in this situation? And, do you believe that this is indeed the cause? Thank you much.

I would suggest it works over RPC, so you have to open 135 and high ports between the servers (IPs) you want to see each other.

I'm not sure this complain with your firewall policy, though.
