Interface eth0 missing after messing around with bridge
I'm having a bridge (bridge-utils) problem in Mandriva 2006. I was trying to connect my computer and my laptop using another computer with Mandriva 2006.
So far, I can't make it to work.. but that's not the problem I'm asking. See, when I'm deleting the bridge using brctl, it refuses to do so.
so when I typed this to delete my bridge, br0:
# brctl delbr br0
can't delete bridge br0: Operation not permitted
That's not all, it looks like my ethernet interface also gone. I swear it was there before I'm fiddling with this bridge stuff, I can even work my way with samba to get some files from my other computer connected by wire.
# ifconfig eth0 up
eth0: unknown interface: No such device
My wild guess is that my eth0 somehow renamed to br0, because when I'm trying to set up a new network interface from Mandriva Control Center and chose "LAN connection", it suggest "br0: D-Link Inc|DFE 530 TX+ Fast Ethernet Adapter" as it's default option. While before this mess, I remember it suggested "eth0: D-Link Inc|DFE 530 TX+ Fast Ethernet Adapter" as default option. When I 'upped' this br0 (ifconfig br0 up) , it works and I can send ping from my other computer as if it was eth0.
For additional information (just in case it's related to my problem), I'm using Shorewall and I already remove br0 from /etc/shorewall/interface file. I also delete /etc/sysconfig/network-scripts/ifcfg-br0.
I know this might sounds silly, but I want my "eth0" back.
Oh, and sorry for my English because I'm not a native-english speaker.
