<RESOLVED> Router commuincation with DSL

gentoonu-b · Tux's lil' helper Joined: 05 Aug 2005 Posts: 75

I have a Linksys router model:WRT54GS.
I have 3 & 1 printer (via Jetdirect) PC's on my mini network.
1 -PC is FC4, 1-PC in WinXP , & 1-PC is Gentoo
Obviously the PC in question is the Gentoo.
I am able to successfully connect via DSL to the interenet thru the FC4 PC and the WinXp PC. The good news is that all the deives on the network can see each other, when I do a ping. The router has been enabled as DHCP server as well as disabled. The Gentoo PC wouldn't allow for it's Ip address to be dynamically assigned. I wasn't able to ping any of the other devices until I statically assigned the IP for this particular PC. All the other PC's recieves IP's dynamically.

So the problem is the Gentoo PC can't connect out side the router, it does see the router. If i ping www.NFL.com I get: "unknown host". I can't ftp anywhere either (obviously). What am I missing? And why is there no nslookup command in Gentoo?

Thnx Gurus'

As a test see if you can ping an external IP address rather than an external name (216.19.170.248 for www.nfl.com).
This will tell us one of two things
1) You can ping IP addys, so your name resolution needs set up
2) You cannot ping IP addys so your network needs setup

Option 1 is probably the easiest to solve, if you are connected but not resolving names update /etc/resolv.conf to the following:

Is there a way to run networ setup without the install cd.
I was able to connect thru DSl without the router just fine. It's just once I installed the router then this occured.
Thnx.

I don't know how to setup Gentoo for Dynamic.
I can switch the router either way it doesn't give problems.

This what I input to switch to static. I commented out all the other lines but the one below.
/etc/conf.d/net
iface_eth0="192.168.1.103 broadcast 192.168.1.255 netmask 255.255.255.0"

previously this was the settings for net
iface_eth0="dhcp" < This at first wasn't commented out. But now is.>
#dhcpcd_eth0="...." <This has always been commented out. I don't know what it means"
I also accidentally removed the Gateway entry, but I don't know the correct syntax to re-input. < When it was there dynamic still didn't work>

Thnx

as funky said, youre not having a total connectivity problem based on what youve described. It sounds just like a simple DNS issue. Make sure to add your nameservers to resolv.conf in the /etc dir and you should be fine.

Alright ya'll
I've made the following changes
/etc/conf.d/net
1) iface_eth0="dhcp"
2) gateway="eth0/192.168.0.1"
3) rc-update add net.eth0 default < Wasn't sure if I was suppose to run this at the command line or input into /etc/conf.d/net, so I did both>
4)Commented out all other lines.
& made sure /etc/resolv.conf had the following
5) nameserver 192.168.1.1
domain translucent < my domain name>
6) I made sure the router was set for DHCP
7) I then rebooted.

I tried to ping 192.168.1.1.....unknown host
So I typed ifconfig eth0 inet up..and then tried to ping still same message.

What am I missing? Should my nameservers reflect the ISP's DNS or my router?
Thnx ya'll

In addition to m_sqrd if the rc-update line is still in your /etc/conf.d/net remove it.

THe gateway was a miss type it is 192.168.1.1.
And rc-update has been removed.
Thnx
But still not getting through.

This what I input to switch to static. I commented out all the other lines but the one below.
/etc/conf.d/net
iface_eth0="192.168.1.103 broadcast 192.168.1.255 netmask 255.255.255.0"
I was then able to ping the router and other devices on the network. I just couldn't get access outside to the internet.

I appreciate all the input and patience.

Ok so now your box is getting its IP address from you DHCP/router but you still can't ping the router (is that correct) or is this a DNS issue you can ping by names?

iface_eth0="192.168.1.103 broadcast 192.168.1.255 netmask 255.255.255.0
The above command allowed me to set the IP statically. So I could ping the router and the other devices on the network. I ping by IP addresses

Ok no problem I was Just trying to see what you had now.
Ok you can ping your router and you can ping 66.219.59.46 (www.gentoo.org)
but you can not ping www.gentoo.org by name correct.
if that is so can you post you current /etc/resolv.conf and /etc/nsswitch.conf

Ok...okay..
Here's the update please, learn from my mistake.

The problem I had trying to connect to the network via DHCP.
resoution for me was simple.
2 things
1) emerge dhcpcd <When you are first setting up the network connections>
2) /etc/conf.d/net
iface_eth0:"dhcp"
iface_eth0:"dhcpcd"

I rebooted and all of a sudden it works....Ta Da!!!!

Thxn to all the moderators, and my forum buddies for your insight and patience.
