Overene to nemam, nabizim IP atd. jenom pres eth0, nicmene
dokud jsem to neomezil, prichazely i pozadavky z druheho segmentu.

na www.isc.org se pise:

route add -host 255.255.255.255 dev eth0
On Linux 2.0 systems with more than one network interface, assuming that
your kernel includes SO_BINDTODEVICE support, which is required in order to
support more than one interface, you may have to add a route to the
255.255.255.255 broadcast address on every interface - just do the route
command, as shown above, substituting the name of each network interface in
place of "eth0". Because of the way SO_BINDTODEVICE works, it is not a
problem to have more than one of these routes.

Mam jeste jeden dotaz - jak se resi zaloha dhcp proti vypadku (HW, SW), kdyz
to
nejde jako napr. u DNS /primar - sekundar/. Co kdyz bezi dva servery
(kdo driv prijde, ten driv mele?). Jak prenaset automaticky konfiguraky,
abych nemusel upravovat dvakrat dhcpd.conf rucne dvakrat ci prenaset ftp
nebo plodit nejaky skriptik, lze to nejak? A pokud jsou konf. jine
(Linux x UnixWare). Namety?
