be careful of zeroconf


I use my Debian testing as a gateway, running dhcp service and ipmasq. But after a dist-upgrade today and reboot, I found I can not connect to the internet from this machine. My settings in network/interfaces seem to be no longer working, and strange addresses like 169.254.x.x are assigned to the two NICs. After two hours of searching and trying, I found the problem is network/if-up.d/zeroconf. Google told me that this thing is used to easy the connection between two machines, but actually it cracked down my gateway I really don't know why debian somehow thought I need this package and installed it for me. Removing this package resolved the problem. And it didn't remove the file if-up.d/zeroconf, leaving it running with an error message. I deleted it myself.

When you removed the zeroconf package, did you do a purge in the uninstall? When you don't do that, the configuration files for the package get left behind as orphans (sometimes this is a good thing, such as when you are uninstalling because of an upgrade or something.)

Also, I just noticed that you use FC4. Do a route -n on that sometime, and I bet there will be a route to 169.254.0.0 in there as well. The Redhat stuff has been doing zeroconf for years, and the way to get rid of it there is by editing /etc/sysconfig/network and adding a line that reads ZEROCONF=no.

Thanks for the purge thing. I normally don't mind configuration files are left after package is removed, but leaving a script that will still be executed is definitely unacceptable.

And yeah, I did a 'route -n' on my fedora box and '169.254.0.0' is there. Guess I'll leave it there since it didn't cause any problem for now and it didn't try to assign such an IP address to my NIC.
