I don't have a modules.conf. I have modprobe.conf and it has alias entries for network adapter/driver. I added "alias br0 bridge" but no change. During boot something is trying to call the bridge up but it can't find brctl. Loopback loads then bridge then the three network cards. This may come as no surprise but I just discovered that even though I was able to build the bridge, when I performed a ifup br0 I got the same message I get at boot time. I'm wondering now if I didn't get brctl installed properly. I never found definitive installation instruction so I wondering if anyone knows the installation procedure. Do I do a "configure" then a "make" and then a "make install" or just "install"? Bert Hubbs McGlinchey Stafford and Youngblood & Bendalin, PLLC 2711 N.

BUT from the previous statements, it doesn't work that way for Bert. As I mentioned my compile of the module has all those nasty undefined symbol errors so until I get that right all I can do is talk about the way other modules work. Is that fragment from brctl BTW?

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. >> > > > Wrong!
