Re: linux-ipsec: canonical name of a machine

Unfortunately, there is no such thing as "the" canonical address of a machine. Addresses belong to interfaces, not machines; a machine with multiple interfaces has multiple addresses, period.

To test whether an address belongs to the machine, you need to use something like the SIOCGIFCONF ioctl, or the output of "ifconfig", which gets you a list of the machine's interfaces. (There really ought to be a /proc file for this, but I don't see one...)
