So Linux does not have a "PATH" while booting? I have brctl in the /bin and the /sbin directory. I looked at the /etc/init.d/network script and there is mention of bridges but no direct call to brctl. Do you think I would be better of recompiling the Kernel with bridging built in? Well... You need to determine what script the error is coming from... Probably /etc/rc.d/init.d/network (or it could be /etc/init.d/network) Bert Hubbs wrote:> " That sounds like you need the full path to brctl in your script." > > What script? > > > > Bert Hubbs > McGlinchey Stafford and > Youngblood & Bendalin, PLLC > 2711 N.

Yep! First lsmod I got no bridge. Second lsmod after modprobe bridge I got bridge listed. So here comes the $35 question. How do you make the module load at boot? After Googleing modprobe, lsmod, insmod there seems to be know way to use modprobe to load modules at boot. I came across discussion to add it to modprobe.conf but others said this would not cause it to load at boot. Another mentioned rc.local but I'm not sure that rc.local will load at the right time. On the other had that may not matter but I'm in to cleanliness. Any suggestions? Bert Hubbs McGlinchey Stafford and Youngblood & Bendalin, PLLC 2711 N.

Finding that script can be... interesting. One thing you almost certainly want to check is to see if bridge.o is being loaded. Use lsmod as root to see if it's loaded. If it is loaded, then you almost certainly won't need to rebuild the kernel. If you don't see it loaded, try modprobe bridge and re-check with lsmod. If it loads, again, no kernel rebuild needed.

When I start Linux I get an error: "Bridge support unavailable: brctl not found". And then eth0 - 2 load with no problems. After system is up I can build the bridge but it does not survive a reboot. Do I need a startup script or should the bridge build from the: /etc/init.d/bridge /etc/sysconfig/network-scripts/ifcfg-bro /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/ifcfg-eth2 I am using Core2 The information contained in this e-mail message is intended only for the personal and confidential use of the recipient(s) named above.

That sounds like you need the full path to brctl in your script. Which leads me to MY question for the list. I'm having problem getting bridge.o to build correctly on 2.4.25 (linus). Is this a case where I'd be better off with it built static?

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.

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?

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 :(> On Tue, 13 Jul 2004 11:17:51 -0500 > Stephen Hemminger <shemminger@osdl.org> wrote .. > On Tue, 13 Jul 2004 11:17:51 -0500 > "Bert Hubbs" <bhubbs@mbgdocs.com> wrote: > > > Yep! > > First lsmod I got no bridge.
