Hello,
I am running RHEL-4 on my office PC. Before few days i was able to access the internet through that pc, but now i am having problems.
1.Even i am not able to ping 192.168.0.12 (self machine)
2.Proxy server IP is 192.168.0.16
Please help me to resolve the issue.
Thanks & Regards
Girish Sharma
If nothing has was changed to cause the internet to stopped working I would suspect a hardware fault on the network card, or your administrator has blocked you on the proxy server.

Thanks for your reply.
I have checked that network card is working fine as i checked through system-config-network, but it is showing me "Inactive" eth0. Administrator has not blocked any site or proxy server.
It is not self pinging, i have checked that i have given right proxy server's IP address in proxy setting of Firefox browser.
Please help me where and what to do to get resolve the problem.

First of all i wish to thank to you for your reply and script. After running and/or restarting the machine now i am able to ping self i.e. 192.168.0.12 and 192.168.0.16 i.e. proxy server. It is accessing internet in windows but returning the proxy server error in RHEL. Machine is having dual OS i.e. windows XP and RHEL.

i have given right 192.168.1.1 default gateway in network setting dialog box (system-config-network) and then
service network restart
service network reload
But, still i am not able to access internet.
Thanks & Regards
Girish
as you told that your proxy ip is 192.168.0.16
but u are using 192.168.1.1 as a gateway
remember both are different ip address.
as when you run the command ifconfig it showed the informaion
192.168.0.255.
i do think this is your gateway
put this entry in /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth0
then restart the service
then try
hope so should work
I have put this entry (192.168.0.255) in /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth0 and then restartd the service, but still it is not working. I am confused what should be ip of default gateway; i.e. 192.168.1.1, 192.168.0.12, 192.168.0.16 or 192.168.0.255.
Enter the Proxy server IP as the Gateway Address and restart the service or restart the PC If it does not work run the script you used earlier and post the results.
