Here's an interesting way to blow up your box, providing IPv6 is a module: ifconfig eth0 up 192.168.1.1 ifconfig eth0:0 up 192.168.1.2 modprobe ipv6 ifconfig eth0 down ifconfig eth0 up 192.168.1.1 ifconfig eth0:0 up 192.168.1.2 *kaboom* Here, you'll either get a non-fatal Oops complaining about a null-pointer dereference, or a continuous Oops scrolling up your screen at warp 43 (or should that be warp 6? :), with the box locked totally dead. In 2.1.12, I had both ip_alias and ipv6 as modules, in 2.1.13 I moved ipv6 into my kernel. In the first case, my bootup scripts were able to add the IP aliases without harm, because IPv6 wasn't yet loaded. If I then loaded ipv6, *kaboom*. In the second case, ip_alias refused to load, and so my bootup scripts did nothing (thankfully, or I would've had a bit of a problem on my hands...) Anyone wanna take a look at this one? :) -- Jeffrey Connell | Systems Adminstrator, ICONZ ankh@canuck.gen.nz | Any opinions stated above are not my employers', ankh@iconz.co.nz | not my boyfriend's, my priest's, my God's, my #include <stddisc.h> | my friends', and probably not even my own. ---------------------------+-------------------------------------------------- Fingerprint: 1024/2B8B116D | Key at http://www.canuck.gen.nz/~ankh/pgpkey.html | ||||||||||
