It could be a proxy server, like someone else said. Or you could have the wrong IP Address and or Gateway. Check with an administrator of the network there and see what they say about it.

Actually i have installed Linux and Windows xp on the same machine...
The browser in XP run perfectly fine and connects to the internet..
But in Mandrake Linux 10 .. the browser doesnt connect to the internet...
im using the same IP, Gateway and otehr settings that i use for XP ..so i guess there is nothing wrong with these settings..
i dont think we have proxy server...

And one more thing is that we are able to connect to any other computer on our campus using telnet or ftp in MANDRAKE LINUX...its just the internet that doesnt work....
And yes i can use the browser of another machine working on linux to connect to interent..and it works fine... using "setenv DISPLAY IP" command...


I typed the command "ifconfig -a" and it gave me the following

eth0 Link encap:Ethernet HWaddr 00:11:2F:15:4C:B0

* I am sort of assuming that you mean that you dual-boot to Linux or Windows XP, and not that you are doing something else like power pc (I know nothing about) or Vmware (I know lots about). But what I'm saying is when you are in Linux, you are in Linux only ... nothing else under it?

* Are you in Syracuse New York? If so, it is 10:17 pm and you shouldn't still be in school anyway ;-) But then again there are all kinds of schools...

Search results for: 139.127.174.38


OrgName: SUNY Health and Science Center
OrgID: SHSC-1
Address: 750 East Adams Street
City: Syracuse
StateProv: NY
PostalCode: 13210
Country: US

* Let me see, can you send output of "netstat -r" ? And see if you can ping your default router?
If so, can you ping something by host name like www.google.com?

Sometimes what seems as a connectivity problem is actually a DNS resolving problem. Send the output also of "cat /etc/resolv.conf" and let's see what the DNS servers are you are using.

You should be able to resolve host names with "host www.google.com" should give back a bunch of info. (sorry I'm not in Linux right now for an example, I'm kind of winging it right now) including the IP Address. (or "nslookup www.google.com").

Did you enable any kind of Firewall setup in your linux installation? If so it is also possible that you have a default to block all, or certain things. IPTABLES is the Linux packet filter and firewall core stuff. Typically Redhat Linux or Fedora Core have graphical methods of configuring it. Mandrake probably does too. You might want to try "iptables -F" and then try connecting to things again. That insures a clear open (no blocking) firewall tables.

I've used Shorewall myself lately, and I've had to add all sorts of things to my firewall to allow things I needed to do. Including basic web browsing. I do NAT and Connection Sharing, and I run ISC DHCP (the full thing, not just the client that comes with distro's). But then again I have to share my connection, whereas you probably do not have to.
