[gentoo-user] Network Down Apps trying to use lo instead of eth0

[gentoo-user] Network Down Apps trying to use lo instead of eth0

[Bo Grimes]

I rebooted and my network is "down."  eth0 is actually running, but
from what I can tell my applications like Evolution and Firefox are
trying to use lo.

I have the link set up

# cd /etc/init.d
# ln -s net.lo net.eth0

/etc/conf.d/net has config_eth0=( "dhcp" )

rc-update add net.eth0 default returns that eth0 is already default.
I can see it come up when I boot, but lo also comes up.  I don't
remember ever creating lo.

Check the output of route.  It should tell you what it is using for the
default gateway.  You can also use route command to set the route. 

Hope that helps.

Thanks.  Here's what I get:

Destination     Gateway        Genmask          Flags    Metric
Ref   Use     Iface
192.168.2.0       *              255.255.255.0         U           0
        0      0         eth0
loopback           *              255.0.0.0                U
0           0      0         lo

Let me try that again.  Sorry.  Using Gmail's web interface and I seem
to have botched the formatting.  The results of route are:

Destination     Gateway        Genmask    Flags    Metric   Ref   Use  Iface
192.168.2.0       *              255.255.255.0  U           0      0
   0      eth0
loopback           *             255.0.0.0          U           0
0      0       lo
default        192.168.2.1       0.0.0.0          U           0      0
     0      etho

Well, I'm on a stinking dial-up but yours looks like mine as far as
gateways are concerned, yours is eth0 and mine is ppp0.  Do you have
iptables installed and it may be blocking something?  Maybe?  Just in
case I am missing something, here is mine:

root@smoker / # route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
209.215.30.14   *               255.255.255.255 UH    0      0        0 ppp0
192.168.0.0     *               255.255.255.0   U     0      0        0 eth0
loopback        *               255.0.0.0       U     0      0        0 lo
default         209.215.30.14   0.0.0.0         UG    0      0        0 ppp0
root@smoker / #

eth0 is a local thing here.  Disregard it on my route.  It isn't even
connected at the moment. 

Now that my IP is out there, pardon me while I reconnect.  Don't get me
started on Gmail.  I don't get a copy of my replies and am hoping to do
a work around pretty soon.
