Connection Refused.....

HI There,

I'm experiencing some difficulties connecting from linux to my SQL
server. I've checked and SQL is definitely running for the reason I can
telnet into localhost on port 1433 (telnet localhost 1433). Now the
thing that baffles me is that I can't telnet into it when using the
servers IP address (10.1.0.5). I've even tried to do a port scan from
linux with nmap and port 1433 is definitely not showing in the list as
an open port. Do I need to setup some sort of policy somewhere for the
port to accept incoming connections from other hosts?

Kind Regards
Stephan
