Network Manager - Two eth0 connections?


Hello -

I am running Fedora 8 -- no dual boot or anything. I have a static address and a dns name as well. I've been having some trouble with having an active connection at boot. Network manager consistently shows that my network connection is inactive.

I created a new profile in Network Manager which is nicknamed eth0:1

Now /sbin/ifconfig shows
Quote:
eth0 Link encap:Ethernet HWaddr 00:08:02:40:7E:7D
inet addr:10.1.100.81 Bcast:10.1.100.255 Mask:255.255.255.0
inet6 addr: fe80::208:2ff:fe40:7e7d/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:78050 errors:0 dropped:0 overruns:0 frame:0
TX packets:6564 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:11536633 (11.0 MiB) TX bytes:554703 (541.7 KiB)

eth0:1 Link encap:Ethernet HWaddr 00:08:02:40:7E:7D
inet addr:10.1.100.204 Bcast:10.1.100.204 Mask:255.255.255.255
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
It seems that eth0 shows a dynamic inet addr while my static is .204 in eth0:1

cat /etc/networks shows
Quote:
default 0.0.0.0
loopback 127.0.0.0
link-local 169.254.0.0

Can this be cleared up? How can I ensure that eth0 is active on boot.

I thank you for your time.

Best,
D

Hi!

One querry, that how you decided that eth0 shows dynamic inet address ? What is the static IP you configured for eth0 inetface.

To ensure that eth0 is active on boot check under "/etc/sysconfig/network-scripts/ifcfg-eth0" have an entry ONBOOT=yes

and execute command "chkconfig network on" on console/teminal to make network service start-up at boot up.

regards,
PK

Aaaah! NOW I see it... I still have to FIX it, though! The first static address I gave this computer was 10.1.100.81. Then, our network administrator took that number back and gave me .204.

Interesting, I can hit the apache server by pointing my browser to 10.1.100.81! The eth0:1, (which is the active address in Network Manager) is showing 10.1.100.204.

I have no file called ifcfg-eth0
I do have a file named ifcfg-eth0:0

Hmmm... where should I go from here.

Thank you!
