Synopsis: ifconfig+alias State-Changed-From-To: closed->open State-Changed-By: cjc State-Changed-When: Sat Jun 8 18:04:59 PDT 2002 State-Changed-Why: No, there is a bug here. Look again at the last configuration (my '^'s added), nevermind# ifconfig fxp0 fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet xxx.xxx.x.10 netmask 0xffffffc0 broadcast xxx.xxx.x.63 inet xxx.xxx.x.20 netmask 0xffffff00 broadcast xxx.xxx.x.255 ^^ ether 00:20:ed:29:33:33 media: Ethernet autoselect (100baseTX <full-duplex>) status: active nevermind# ifconfig fxp0 inet xxx.xxx.x.20 netmask 255.255.255.192 alias ifconfig: ioctl (SIOCAIFADDR): File exists nevermind# ifconfig fxp0 fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet xxx.xxx.x.10 netmask 0xffffffc0 broadcast xxx.xxx.x.63 inet xxx.xxx.x.20 netmask 0xffffffc0 broadcast xxx.xxx.x.63 ^^ ether 00:20:ed:29:33:33 media: Ethernet autoselect (100baseTX <full-duplex>) status: active The bug here is that the netmask and broadcast _are_ changed despite the fact that an invalid alias is being added. When ifconfig(8) errors out like that, it shouldn't be leaving a broken entry. http://www.freebsd.org/cgi/query-pr.cgi?pr=38672 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
