Local LAN and WAN problems...

Sunshine Aguilar — Wed, 22 Jan 2003 18:39:41 GMT

I have a local LAN that is NetWare based (pure IP). I created a NetWare client for Linux that uses pure IP. My local LAN is DHCP configured from the NetWare server.

When I dial up to the internet, it verifies my password and username, but after it connects I cannot view web pages or ping any ip's on the net. I do have the DNS addresses configured for the WAN, so I don't believe the problem lies there. I can still ping my Novell server just fine, and still view the shared volumes just fine, so the LAN is not effected.

Any ideas?

DNS comes from where?

Does the Linux server do that?

Is the Linux server supposed to be providing Internet access, acting as a firewall?

I have a black hole firewall configuration for a Linux box that does that. Its actually posted in one of the Linux forums as of yesterday.

I need a problem definition to help.

Post the output of following Linux commandds.

traceroute yahoo.com
netstat -r
netstat -an (its long)
ifconfig

Then myself or others can really help.

Mandrake 8.2 guess I should have posted the os earlier?

This is a test server.

The DNS addresses come from the ISP. I configured it hoping that this machine will access the internet and be able to view web pages, and ping other sites.

It will not provide the internet service for the rest of the network (yet), it is just for this machine.

A firewall on this machine would be nice, however not necessary at this time.

Look at
netstat -rn

see where your default route points to.

Are you running a firewall on the thing? Perhaps you need to open it up to let you out.

does
traceroute anyIPaddressOntheWeb

go anywhere?

At this time, I do not have a firewall running.

You cant get the the internet on this box, because you can't resolve DNS(Domain Name Services)

You need to find a valid DNS server from network administration and put it in your /etc/resolv.conf file

Here is mine, attached.

Just change the domain name and put in a valid server and then zap, you're on the net.

If you are doing the net via your ppp interface, you get the dns name from your isp.
