Someone posted, so it was pulled back to the top. Let's hope the problem was solved in a more timely manner than that. I'd agree though that using ICMP as a test is a bad idea. Protocols aren't treated the same by firewalls, ACLs, etc. and many companies block it to prevent the reverse-enginnering of their network. Using netcat ('nc') or telnet to check the connection is a good first check. Couple that with a good network trace or tcpdump and you can normally find the issue fairly quickly. You can also start another SSH daemon on a port (such as 80/443) not in use that's often allowed by default through all networks and see if you're able to connect there. Start simple and work back up the OSI model.

NAME

       pwrkap_aggregate - Present a large number of pwrkap servers as if they were one

SYNOPSIS

       pwrkap_aggregate config_file

DESCRIPTION

       pwrkap_aggregate  is  a	daemon that connects to a multitude of pwrkap servers and power control domains, and presents them as if they were
       one server with a smaller number of domains.  By aggregating pwrkap server instances, it is possible to monitor many thousands  of  servers
       without	overworking the command console.  It is also possible to give identical class designations to a group of pwrkap servers and manage
       them as an aggregate.

OPTIONS

       config_file
	      Text file mapping pwrkap servers to aggregated domains.  See pwrkap_aggregate(5) for information about the config file format.
