could this be an issue of network card???
 
hi all,

i use fedora 5 which dual boots with XP and the sys configuration is below:
mobo : asus kbs series
processor : AMD Athlon 2800+ n 80G HDD with 512 RAM...
there has been a strange prob right from installation of Fedora with this internet , we have a LAN here and after all lan and other network settings being intact , i can ping to all other comps on my network..

now the real problem is i can't connect to internet say neither i can surf in any browser,no messenger works , and even tried yum in vain after configuring it to use with a proxy coz it worked with many of my frenz comps... who use asus and amd ...

even internet settings work perfectly on my XP ...

i strongly feel that there are no probs regarding network settings as i myself have configured successfully the same on many of my frenz comps.. and even my firewall is disabled..

plzz donn feel bored and i go here providing as many details as i can:

a sample output of nmap with one of the servers is below n works intact..
Code:

[root@localhost ~]# nmap 172.31.100.18 -p3128

Starting Nmap 4.00 ( http://www.insecure.org/nmap/ ) at 2007-01-29 19:55 EST
Interesting ports on 172.31.100.18:
(The 1663 ports scanned but not shown below are in state: closed)
PORT    STATE SERVICE
3128/tcp open  squid-http

Nmap finished: 1 IP address (1 host up) scanned in 13.959 seconds

kernel version:
Code:

[root@localhost ~]# uname -r
2.6.15-1.2054_FC5

as it might be required the output of /sbin/lspci
Code:

and somthing regarding "wget"
Code:

this output is same as on my frenz comp.. so that shudn't be a prob..
[root@localhost ~]# wget http://djha:djha@172.31.100.18:3128/yahoo.com
--20:07:29--  http://djha:*password*@172.31.100.18:3128/yahoo.com
          => `yahoo.com'
Connecting to 172.31.100.18:3128... connected.

hope u reached here... now as i have mentioned earlier too net works intact on my XP but doesn't on Fedora , i feel it can't be a problem of my network card... but what it could be then???

any valuable suggestions are appreciated...

regards
Vijay.

I'm guessing you don't have your gateway properly configured. What is the output of:

$ netstat -rn

Also, check that your DNS server is properly configured in /etc/resolve.conf. If you can't ping this:

$ ping -c3 www.linuxquestions.org

but can ping this:

$ ping -c3 64.179.4.146

Your DNS is not properly configured.
