Problem Getting Online

Problem Getting Online

[Christopher Gray]

Hi:

The battery died on my tower and so I'm working to get things back in order. 
However, Ubuntu seems unwilling to allow me to connect to the internet.  I 
have a vague memory of an "auth" command I once entered a few years ago to 
resolve this issue.

Any advice to get me back online would be greatly appreciated.

Chris

Can you give us more info?

What type of connection do you have?

What have you done so far?

Geoff.

Hi Geoff:

It is an ethernet connection.

So far, I have only checked my notes and History which hasn't revealed very 
much.

I'm going to assume it's an ethernet connection to a modem/router.

First, you'll want to see if /etc/network/interfaces has something like 
the following:

iface eth0 inet dhcp

This should be the default.

If it does, see if your interface is getting an address by running:

/sbin/ifconfig eth0

If it's up it should have an address and should say "UP BROADCAST". 
Here's what mine looks lke:

eth0      Link encap:Ethernet  HWaddr 00:1e:4f:d9:dc:14
           inet addr:192.168.2.101  Bcast:192.168.2.255  Mask:255.255.255.0
           inet6 addr: fe80::21e:4fff:fed9:dc14/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
           RX packets:7284830 errors:0 dropped:0 overruns:0 frame:0
           TX packets:6643140 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:1000
           RX bytes:3478879179 (3.2 GiB)  TX bytes:1062914569 (1013.6 MiB)
           Interrupt:21 Memory:fe9e0000-fea00000

If your interface isn't up but you do have the DHCP entry in 
/etc/network/interfaces, try looking in /var/log/syslog for DHCP output to 
see what's going on.

If your interfaces file looks different, what's in it?

Geoff.
