Problem connecting to internet (linux newbie)

[samboy]

I am using a D-Link DFE-538TX 10/100 Adapter at the office
and we are using a proxy running on windows NT to connect
to the internet. I tried to configure the proxy settings in the
Konqueror using the settings I am using when windows but
i cant still connect to the net.. it just says connecting to site...

when i run ifconfig, i got the ff. can anyone please help me..
i really wanted to move to linux... thanks!

knoppix@ttyp0[knoppix]$ ifconfig

Well it certainly looks like it gets an IP ok have you checked in the /etc/resolv.conf to make sure that the nameservers are set porperly? The contents of the file should look similar to this:

[05:28 PM Fri Nov 07: stephen @ ~]
>$ cat /etc/resolv.conf
search wolf
nameserver 192.168.1.10
nameserver 192.168.1.34

The search line and the second nameserver line are not necessary you just need one nameserver.

I tried doing that and it returned the ff:

search (null)
nameserver 129.1.2.122

BTW i log into a firewall when using win2k.
also when using mozilla, the status is connected.
i know i got the proxy settings right because when
i use a different proxy, it will return an error. but
with the right settings, there are no errors, but
there's also no page displayed..

plaese help..

That does not look right for the nameserver unless you are running your own DNS server on the netwrok you would need the namserver (DNS) from your own ISP to put in the file. Are you using NAT on the w2k firewall? How do you get the IP's you are using? Can you use ping or traceroute to get to the other machine(s) on the network or an address outside your network? To use ping or traceroute open a console window (clam shell icon on taskbar) and ping www.cnn.com or ping xxx.xxx.xxx.xxx, traceroute www.cnn.com or traceroute xxx.xxx.xxx.xxx replace the xxx's with an actual IP. If you could would you post the output of the traceroute and ping commands so I can see them.

i don't know yet about the NAT & DNS things.
our admin is not around yet but what i know is
that a DHCP provides IP for the workstations.
i also tried ping & traceroute commands for our
proxy and got the ff:

PING:
knoppix@ttyp0[knoppix]$ ping 129.1.2.57

thanks!

Ok that shows that you can get to the other machine how about when you try to go outside the network using the www.cnn.com or 64.236.24.28 (one of the IP address for cnn) can they be reached? What is the contents of the /etc/resolv.conf when booted from the CD your nameserver should be in there automatically, when booting Knoppix should have got that information from the DHCP server.

i'll try but i don't think it will work because i tried pinging
the CNN ip in win2k but got request timed out..
i'll try though...
