Connecting to Internet


I have recently installed RH Linux 8.0 on a new Dell box. Not running DNS nor DHCP. This box can be accessed from the LAN without problems. I can also SSH into the box without problems. I can nslookup both the host name and it's IP. But, I can not startx and from there access the Web. The message "The operation timed out when attempting to contact www.redhat.com" is displayed after a 5 or 10 second delay. Any ideas?

Does this box have *any* kind of internet connection at all?

For instance, if you were to :

traceroute www.yahoo.com

what does that give you?

What network card(s) do you have in the machine, and what's your normal access route from your LAN to the internet?

Slick.

I have LAN connectivity. Other users can access Web pages on this box and I can access other boxes using nslookup and I can log onto other server via ssh. For security reasions this box has a 172.16.n.n IP address and I suspect this is the reason I cannot access anything outside our WAN. I am considering installing another NIC and configuring it with a publically accessable address. I can then activate or deactivate that card when I want to go to the network to fetch updates and patches. If you know of another solution please let me know.

This seems rather vague.

>Other users can access Web pages on this box

How? What are they doing, that you're not?

>I can access other boxes using nslookup

What other boxes? Are you looking up names on your local subnet, or internet names?

>For security reasions this box has a 172.16.n.n IP

um.. I don't think that gives you much security. It's more likely that this is the address space of your local subnet. This is a private ip address and not routable across the net. So you'll have to have some gateway (firewalled hopefully) that will allow you out. Of course, if it's *not* your local subnet, and you're plugging this IP into a completely different subnet, it's not going to work. Likewise, sticking a card into your machine, plugging it into a 172. network and giving it a public ip address isnt' going to work either...

Without some kind of details about your networking infrastructure I really can't help much more.

Slick.

Hmmm ... if this is specific to this one
box ... what do the others have, and HOW
do they see it, in the first place? :)

I would think that (given the symptoms and
not knowing ANYTHING about the entire
network) the RH machine just lacks a route
and/or name-server entry :}

Cheers,

Yah.. I would have thought that 'cept he said :

>Other users can access Web pages on this box and I can access other boxes using nslookup

Which would imply he has some kind of connectivity, and a nameserver defined.

*shrug*

Depends ... maybe his admin didn't bother setting up
DNS and just has a hosts file creeping around :)

That's what I do at home ... why set up
DNS/DHCP for a few machines? ;)

Cheers,
Tink
