 |
|
i'd like to be able to configure my laptop to use 2 different networks... cable modem at the house and the campus network if i manage to find an ethernet port at school. what's the easiest way to switch between the 2? i was thinking i could make a bash script to edit /etc/resolv.conf and run ifconfig and route... i havn't done much scripting before, but if i did this would it have to run as root?
is there an easier way to do this, or should I just go with the script? |

| hmm... i don't use dhcp, and don't have a manual entry for it. now that I think of it, though, I will probably need to use dhcp on the school network, although I plan to continue using a static ip on the house network because of port forwarding. |

does anybody know if it is possible to alias an ethernet intface?
i.e.
| Code: | # /etc/modules.conf
alias eth1 eth0 |
if that would work you could just use a new campus runlevel and switch over that eth1 network when you on campus...
i have no idea if aliasing ethernet interfaces is possible but if that works i don't think it would be to hard from there on out...

Yes you can do some IP's on same interface
| Code: |
XXX root # ifconfig eth0 AAA.AAA.AAA.AAA netmask 255.255.255.0
XXX root # ifconfig eth0:1 BBB.BBB.BBB.BBB netmask 255.255.255.0

You can get a dhcp server to give you th same ip address time and time again if you specify it in dhcpd.conf
| Code: |
host foobar {
ethernet xx:xx:xx:xx:xx:xx
address yyy.yyy.yyy.yyy
}
|
or something along those lines. can't really check at the mo cos my gentoo server is in pieces...  |
