Fedora Core3: Problem in connecting internet

Hi everyone there,

Here is my system report.
Intel Pentium4
OS: Linux Fedora Core3 and WinXP

I am facing problem in connecting internet through gateway in linux. I have tried everything almost but failed. The following is the content of the file useful to you for identifying the problem.

file: /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
USERCTL=no
ONBOOT=yes
BOOTPROTO=none
BROADCAST=192.168.1.255
NETWORK=192.168.1.0
NETMASK=255.255.255.0
IPADDR=192.168.1.26

file: /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=asifqa.abacus

Remember, I can ping the other system in my LAN successfully, but cann't connect internet. I can ping my gateway as well.

The DSN setting is also fine, but nslookup command does not work.

I have used system-config-network command to perform all settings.

Plz help me as it is really bothering me.

Thanks in advance

Are your ISPs nameservers listed in /etc/resolv.conf?

Code:

; generated by /sbin/dhclient-script

nameserver 205.244.112.20

nameserver 206.74.254.2

nameserver 207.40.113.20

nameserver 204.116.57.2

Is /etc/hosts correct?

Code:

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1      uilleann        localhost.localdomain  localhost

192.168.0.1    modem

192.168.0.2    bones

192.168.0.3    tinwhistle

192.168.0.4    uilleann

Fedora Core 3: Problem in connecting with internet

yes, the /etc/resolve.cnf has following contents:

; generated by /sbin/dhclient-script
nameserver 202.147.176.40
nameserver 202.147.176.41

i think so, these are the DNS servers, i have also set in xp

and the contents of /etc/hosts is:
127.0.0.1 localhost.localdomain asifqa localhost
192.168.1.25 proto
192.168.1.20 salam

proto and salam is the systems on my local network;

Thanks for your reply

Looking forward to your reply

Can you identify the bottleneck with traceroute?

Code:

Fri May 27 06:40 AM root@uilleann ~ # traceroute yahoo.com

traceroute: Warning: yahoo.com has multiple addresses; using 66.94.234.13

traceroute: unknown host yahoo.com

nslookup command also failed.

What to do?

Will it be possible for you to be online in yahoo or msn.....

My id is asifqaiyum@yahoo.com or asifqaiyum@hotmail.com....by the way

I am very disappointed with this situation.

Thanks in advance

Sorry, I am out of ideas, unless your gateway has you blocked.

Mine worked out of the box on my install, but I don't use a gateway.

Please Help me out if u got corrected

please help me out, i am suffering from same problem.

Try to "ping" or better "traceroute" to some host given by IP, instead by host name. If it works, then your problem is in the name resolution - either you incorrectly set your namerservers, or they are not working correctly. But given the fact, that you have 4 of them, it's improbable all of them to be down. So, I suppose the problem is in the router and "traceroute" will fail after the gateway. Check if "ping" to a remote IP gives "Network unreachable", your router's NAT settings, the cables, the firewall settings (particularly the DNS service port), in this order.
