What do you get with

telnet localhost 9100

?

i get this

Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

It appears you have a service listening on the localhost and loopback address at port 9100, if you want to have a client computer access this service it should be set to listen at the host machines ip address i.e. 192.168.1.100:9100 what service is this? Apache, Tomcat? Are you trying to access it on the local host or from a remote machine? Is iptables running?
