Hi!
Есть машинка, у которой на внешнем физическом интерфейсе (eth0)
висит множество алиасов из различных подсетей.
Какой адрес из имеющихся будет в сетевом пакете при инициации
соединения локальным процессом (например, telnet или ssh-сессия).
Я всегда думал что тот, который прописан главным (ifcfg-eth0). На
деле видим другое:
$ /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:30:05:46:09:3F
inet addr:212.69.XX.YY Bcast:212.69.XX.__ Mask:255.255.255.0

Как сделать так, чтобы исходящий адрес для локально сгенерированных пакетов был
212.69.XX.YY - основного на интерфейсе?
P.S. $ uname -a
