[wplug] networking question

[Doug Green]

Hi-
I have a networking question- 2 actually. I'm running RH 7.1 on an Acer 
602TER laptop:

1) Is there a way to set up the /etc/sysconfig/network file so that I 
don't have to change the gateway manually every time? At home I need to 
comment the gateway out (as I use pppoe with verizon online), but I have 
a gateway at work. On the same note, will it matter what I set my eth0 
IP address to? I am using the same setting as at work, and it doesn't 
seem to be a problem, but I'm wondering about the "hosts" file under 
/etc/, where I have defined this IP as my desktop computer at work (ie: 
obviously, if I ssh to my work IP it may not work). Ideally I'd have two 
IP addresses, but I don't... instead, I literally unplug the ethernet 
from the desktop and plug it into my laptop. Any suggestions?

2) How do I restart networking services without rebooting? I tried 
ifconfig eth0 down (and up) which brought the interface down and up, but 
didn't really read the scripts again. Is there something like "service 
network restart"?? Thanks!
