I have seen a very strange behaviour with IP aliasing on 2.4.9-ac11. When an alias eth0:0 is added with a different IP address, all outbound connections start using the alias IP address by default, instead of the primary interface (eth0) address. This is unlike any behaviour I have ever seen anywhere. Unfortunately the machine affected was master.kernel.org, which as a result would send its upload requests to ftp.kernel.org from the wrong originating IP address, thus falling afoul of the ACLs on the latter machine. What is even more bizarre is that zeus.kernel.org, which runs the same kernel (but a slightly different configuration - mostly SMP instead of UP) doesn't exhibit this behaviour... -hpa -- <hpa@transmeta.com> at work, <hpa@zytor.com> in private!
