Unable to "whois" from an IC Shared machine.


Hi there,
I am currently online from a PCLOS 2007 machine which is getting net connected via an XP box. I have a firewall installed on the XP box which allows outgoing TCP ports 21, 22, 23, 80 , 443 and 6667. As a result I can ssh, surf the web, ftp, telnet and use "irC." Unfortunately, networking tools such as whois and nslookup and others are not working on the Linux box, presumably they are being blocked by XP firewall. When one uses whois or similar, is a port assigned in a random manner , i.e there is no "default" port as is the case for HTTP (80) or SSH (22) ? If that is so and I do not know which TCP/UDP port to instruct my firewall to "allow outgoing," what would be the best way to be able to use whois on my linux box ?
It is definitely a firewall issue as I can use "whois" when the former is disabled.

Thanks again ! ( sorry for being a pain so often !)

Uncle.

UPDATE : Thanks for looking. I found the problem. I needed to "allow outgoing" TCP Port 43. Sorry for the trouble.

Not a default port, but a standard one. :}

Glad you found it, and I'm responding to stop the post from
auto-bouncing ...



Cheers,
Tink
