ifconfig + alias

[Tomas Podermanski]

Ja tedy nevim, ale konfigurace v rc.conf

ifconfig_fxp0="inet 147.229.191.135 netmask 255.255.255.128"
ifconfig_fxp0_alias0="inet 147.229.191.136  netmask 255.255.255.128"
defaultrouter="147.229.191.129"

funguje naprosto bez problemu - muzete si na to i pingnout

[root at paja r-tp]# ifconfig
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 147.229.191.135 netmask 0xffffff80 broadcast
147.229.191.255
        inet6 fe80::2e0:18ff:fe98:bb87%fxp0 prefixlen 64 scopeid 0x1
        inet 147.229.191.136 netmask 0xffffff80 broadcast
147.229.191.255
        ether 00:e0:18:98:bb:87
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active


Dokonce funguje i exotika, kde na jednom rozhrani jsou nastaveny
rozdilne masky pricemz jedna sit je podmnozinou te druhe :-)  (taky si
muzete pingnout) 

ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 147.229.96.2 netmask 0xfffffe00 broadcast 147.229.97.255
        inet6 fe80::2a0:24ff:fe2d:8d85%ep0 prefixlen 64 scopeid 0x3
        inet 147.229.97.254 netmask 0xffffff80 broadcast 147.229.97.255
        ether 00:a0:24:2d:8d:85
        media: 10baseT/UTP
        supported media: 10base2/BNC 10baseT/UTP 10base5/AUI
