eth1 problem

SewerBeing · Tux's lil' helper Joined: 29 Aug 2004 Posts: 117

on my laptop, the wireless card is recognized as eth1, I can ping the router with it, however I can't do anything else with it. How do I get it to be recognized as eth0, or make things work using eth1.

SewerBeing,

This is a popular question and I keep posting the answer. I can't find it so I'll not suggest you search.

In /etc/init.d/ create a symbolic link named net.eth1 that points to net.eth0. This will be your script for starting eth1.

In /etc/conf.d edit the file net to add the setup you need for eth1. Use the examples provided for eth0 but change the eth0 to eth1.
Do not mess with the active eth0 entries of course.

With thad done,

the problem with rc-update is this is a fedora core 2 laptop. And rc-update wont work on it. I'm trying your suggestion right now though. Also it will not save the key after a reboot, any fix for that? Could it be the fact that I manually assigned it the ip, and did not use dhcp (no clue how on fedora core 2). Your fix has not helped, trying a reboot. fix does not work.

SewerBeing,

I run a scriot that calls iwconfig to load the key after the interface is up. The iwconfig commands could just be tacked on the end of any script that runs after the interface is up.

FC2 has similar startup mechanisims to gentoo, so the mechanisim can be generalised. Ih gave on on RH, when RH9 came out. I still have a RH8 install I could look at if you need a hand adapting my original post to FC2. Is the startup similar do you know ?

I dont think it has changed from RH9 to FC2. I would be interested in your script. I check on the router and it does show the laptop as attached, yet no internet things work on the laptop. How do I use DHCP (my router is setup as the server) on FC2?

SewerBeing,

The script is just two lines
ifconfig sorts out tthe IP address and brings the network up but does not set the wireless odds and ends, that requires iwconfig.
The contents of the script are

the thing is ifconfig does not give it an ip address. On my gentoo rig (main rig) I need to use dhcp, however I have no idea how to do that on fc2.

SewerBeing,

I got a new toy instead of reading the forums (Colour Laser Printer).
To make dhcp work yo need to run the iwconfig setup before you can broadcast for a DHCP address.

Broadcasting on the wrong channel with the wrong crypto will get yo nowhere.

In RH8 ( I dont have RH9 Installed) the following are approximately equivelent:-

that did nothing, it just ignores the script. What did you mean "iwconfig setup" all the settings are correct. I can ping other computers and the router assuming I manually assign it an ip address. Congratz on the new toy I'm jealous.

SewerBeing,

To get a wifi link up, you need to assign it the wireless parameters such as channel, essid, crypto etc., before you can use it for anything or it will not talk to the other end. If you are using the defualts, expect a 'drive by hacking' any moment. A lot of other people will be using the defaults too. They offer no security at all.

When the radio link is up, you can use it to broadcast for an IP address using dhcp. Somehow, you need to run iwconfig on eth1 (or wlan0 or whatever the port name is for your wifi), then run the network script to get the network an IP address. If you assign it an IP address and it just works all you neibours are probably using your wilreless link too.

As a test, you can run iwconfig to manually set the wifi parameters the run the RH network script manually with

they are correct, I set them myself, even the key is in there. I can ping every computer on my network (192.168.0.X) including the router. However as soon as something goes outside it doesnt work. making it a DMZ server on the router does not help. The last tip did not help either

. Could it be a router issue. BTW no one outside of this house is using my wifi thank you very much.

SewerBeing,

Was your network up when you you did the route command?
You should always have 127.0.0.1, which is the local interface that network transparent things use to communicate. Thats having a network of one PC. Some *NIX thing break without it.

Depending on whats happening, it can take 30 sec for the

well I added it, wouldn't let me make it the default but I added it, still no go. The weird thing is, the redhat network update thing says 24 things need to be upgraded. But it will not dl them.

SewerBeing,

If your WiFi is eth1, you need your default route over eth1, not eth0.
What does /sbin/ifconfig show for your interfaces?

eth1 is my WiFI, there is no eth0 route.

/sbin/ifconfig shows eth1 and lo.

SewerBeing,

The debug info you are providing is a liitle on the brief side.
Can you copy and paste the output of the following commands into a post please?

/sbin/ifconfig
/sbin/route -n
less /etc/resolv.conf
