Cool can't connect to the internet via Lan


Hi guys:

Thanks for any help in advance ^_^

I had problem with my redhat 9.0 that install on my labtop. i tried to connect to the internet through the company lan but with no reply at all.

i am using dhcp to get ip address, and i can ping the dns, i also found if i ping something like yahoo.com, the name can be resolved into correct ip address. i just simply get no reply from the internet.

i have tried to disable my firewall just in case something got blocked, but same result. sad!!

I tried check if the dhcp client service if running at my labtop with ps -ax |grep dhcpcd, but i got no match in the list except this command itself. is that means my dhcp client is not working. but how come i can still got ip address from dhcp server.

any info will be appreciated

Remember a dsl/cable connection is "always on".
So make sure Suse/Linux is not trying to
dial out or use a PPPoe connection. The (Linksys) router should have the DSL PPoe settings/configuration or no settings if using a cable modem and not the Linux/RH/Suse. Alls you need is the eth0 (NIC) activated.
If no go re-boot the cable mdm, then the router and see if it conncts.


Hope That makes sense and is of some help.

Is there a default route set up (check with the route command)

The DNS server may be on your subnet, but you don't know where to go to get out on the net.

Best bet is to ask the companies IT department for the router IP or proxy IP address. You may actually be breaking the AUP.

Could you supply the output of the route and ifconfig commands please?

I assume the company normally uses windows machines? Could you provide a sample "ipconfig /all" and "route print" outputs?

Cheers,

Darren.

If you have name resolution and you can ping the gateway and the nameserver and the proxy, then I don't think you are having issues with your LAN settings.

have you tried using another browser like Links or Lynx ? You will need to set a proxy for them as well. If one of those works, then its a problem with your browser application.

hi guys:

I think i have found out the problem is on my ISA proxy server. my linux box is not able to authenticate with the ISA. i set up all the http proxy settings on the web brower but there is no pop-up window for me to fill in the the user detail.

any comments pls

Perhaps your proxy server requires authentication?

try adding "domain\username" and "password" info to your proxy information.
