[SOLVED] Static Local, DHCP Wireless (Woes)

[irishdunn]

Running ubuntu 8.10 on both boxes, here is what I need:



Here is what happens:

Wireless works fine out of the box with 8.10, card (rt61, wmp54G v4.1), as does wired, (onboard, Abit IP35 Pro)

However here is the hitch, I can either use wireless, or wired... never both. If I connect the wired interfaces then my wireless is still connected but i cannot get to the internet, only can ping things on the local network.

If I dont connect the lan then I can use my wireless and get access to the internet.

I need both, as you can tell from above, lan for the fileserver and wireless so I can get to the outside world.

help!

I just finished a comparable setup, without the gigabit crossover. That is a hardwire connection?

Simultaneous ethernet and wireless was done by this person:

Thanks for the reply, I quickly glanced at his post and will look at it later tonight. I will also post interface configurations on both boxes over the weekend.

If you could explain exactly how you set up your situation I would appreciate it.

The crossover cables are hardwire.

I want to set up this type of scheme:

FileComputer:
ETH0:
ip: 10.0.0.2
netmask: 255.0.0.0
gateway: 10.0.0.1 (Not needed?)

ETH1:
ip: 10.0.0.3
netmask: 255.0.0.0
gateway: 10.0.0.1 (Not needed?)

Wlan: (INTERNET)
DHCP

MainComputer:
ETH0:
ip: 10.0.0.4
netmask: 255.0.0.0
gateway: 10.0.0.1 (Not needed?)

ETH1:
ip: 10.0.0.5
netmask: 255.0.0.0
gateway: 10.0.0.1 (Not needed?)

Wlan: (INTERNET)
DHCP

The wlan right now is a AP that is using wep. but that is my main source for an outside line.

[superprash2003]

i say , you put it on a different ip setup .. like say you get 10.0.0.x ip from your AP.. then between the Main box and RAID box .. setup ip manually as 10.0.1.x ( not 10.0.0.x) .. and make the Main box as gateway and RAID box as client.. its like a mini network.. so when you want to access your MAIN box or RAID box you type in the 10.0.1.x ip.. and the internet would work as usual using the 10.0.0.x ip

Alright here is an update, I still require much help:

Given these two outputs here is how I got it to work:

I have to boot both of the machines up, let them both connect to each network (LAN and Wireless) AT THIS POINT IN TIME I still do not have internet... at this point in time I check my routing tables, there is no entry for 0.0.0.0 .... I also check my /etc/resolv.conf and there is no entries.

SO HERE IS THE FIX:
I then unplug my crossover cable, for just a second. and network manager writes to my /etc/resolv.conf the values you see above, also there is an entry for 0.0.0.0 in my routing table.

What step am I missing that will help me to not have to crawl around on the floor every time I restart these damn machines?!

[irishdunn]

SOLVED:

Set the interfaces that are not meant for internet to have gateways of 0.0.0.0

Network Manager will work properly with this setup!
