Re: [Bridge] Bridge support unavailable

Stephen,

The module will only autoload if /etc/modules.conf is setup for it.  Checking  redhat 7.3, redhat 9.0, WhiteBox EL3, Suse 8.0 and Suse 9.0 systems, none have anything to cause bridge.o to alias to br0.  Those are the only systems I have to look at.  I don't know what other distros like debian or mandrake do for bridge.o.  They might have it in the modules.conf file... Dunno.

So, Bert, you'll need to add something like this to /etc/modules.conf:

alias br0 bridge

The stuff I sent before was in the nature of diagnostics and debugging

I'm still trying to get my beridge.o to build cleanly :(
