Hi hermouche!!

I was wondering if you know how to automagically start the gateway during the bootup of the computer. I think I have the following issues.
0. I have Fedora core 7
1 I have two network connection eth0(local lan) wlan0 which is connected to internet.
2. Using Firestarter I was able to start the gateway where eth0 is connected to the local lan.
3. In order to do that I have to got system-config-network and activate my eth0 as well as wlan0; which actually uses ifup/ifdown for activation/deactivation.

Questions: When ever I start my computer I have manually do all the above step even though the firestarter daemon has been set to start it cribbs while booting, saying that "wlan0 is not active" or eth0 is not active...

I tried do this automagically by doing following in rc.local file
1. /sbin/ifup wlan0
2. /sbin/ifup eth0
3. /sbin/service firestarter start.
but the firestarter doesnot start and wlan0 gives the error " ..dhclient(3143) is already running - exiting."

any solution to automagically start the gateway would be greatly appreciated.

This is the manual process I do
1. in the system-config-network i activate eth0 and wlan0
2. then give command $ /sbin/service firestarter start ---- boom my gateway is up and running without any issue.

Thanks,
watersoup

system-config-network

under General you should enable "Activate device when computer starts" for both eth0 and wlan0

Check also the ONBOOT=yes under the following code for both eth0 and wlan0:

cat /etc/sysconfig/network-scripts/ifcfg-eth0

you should get something like this:

DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:C0:9F:FA:BE:6C
ONBOOT=yes........................................ .........................for both eth0 and wlan0
DHCP_HOSTNAME=localhost.localdomain
TYPE=Ethernet
USERCTL=yes
IPV6INIT=no
PEERDNS=no

Hope it helps

Hi !!!
I think when I do that my wlan does not get activated during bootup and hence the eth0 overseeds the wlan0 and when I start the firewall it tries does not try to get the connection going as one of the network connection (Wlan0) is still inactive. So it makes difficult to get through the gateway automagically.
Most of the time when I do "ifup eth0" internet connection through wlan0 is lost (since it is deactivated) but when I activate the eh0 connection through system-config-network it goes without interupting my original wlan0 INternet connection.

Thanks so much for help.

give the output of :

ifconfig -a
iwconfig
ping localhost


/etc/sysconfig/ifcfg-eth0 and same for wlan0
cat /etc/resolv.conf
cat /etc/hosts

Hi hermouche

I am sorry I wasn't able to check the messages...

Please see the output as you requested. I have made sure that the eth0 is not started when computed goes ON
and I start the wlan0 (which is automatic when modprobe ndiswrapper)
but when I give a command ifup eth0, it deactivates my wlan0 network and tries to acquire network add even though it has static address which makes it little confusing.
Thanks for taking interest in the issue..

How can I connect to the internet in Fedora 6?
I am new in Fedora 6.
I know the basic command.
Can anyone help me?
Thanks.

[hermouche]

this is my guess though:

It seems that NM "Network Manager" and "system-config-network" command are not compatible, so use either the GUI sytem-config-network or the NM "Network Manager" .

Thank you hermouche.
Would you please tell me in detail about the "Network Manager" and "system-config-network" command and GUI system-config-network.
I use the terminal window for command.


Thanks again.
