Ifconfig (DHCP?) configures two IPs in one IF
This problem comes in 8.1-R. I have seen it before and thought I filed a report but cannot find it. I found one (bin/21292) for ifconfig, but it was for two NICs with a same IP. Now is a reversed case One NIC has two IPs. Here is the description: Due to DHCP server down, I manually configured rl0 to 192.168.0.10 for temporarily use. In the middle of working, DHCP came back and assigned another IP on the rl0, now NIC is down due to two conflict IP addresses. rl0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=8VLAN_MTU ether 00:40:f4:d1:23:9a inet 192.168.0.10 netmask 0xff00 broadcast 192.168.0.255 inet 10.10.50.126 netmask 0xff00 broadcast 10.10.50.255 media: Ethernet autoselect (100baseTX full-duplex) status: active plip0: flags=8810POINTOPOINT,SIMPLEX,MULTICAST metric 0 mtu 1500 I tried unplumb/delete rl0, but if does not work. Before the bug can be fixed, is any way to fix the IP without rebooting the machine? -Jin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

At least it did on my desktop that I just tested it on. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

RE: Ifconfig (DHCP?) configures two IPs in one IF
-alias works, also delete works. The 'delete: cannot have - in front of it, otherwise, it gives an improper message; # ifconfig rl0 -delete 1.2.3.4 ifconfig: -delete: bad value This seems telling the 1.2.3.4 is a bad value. It should say: ifconfig: -delete -- bad option/switch Now we know -delete: itself is bad, not the value after it is bad. -Original Message- From: Alberto Mijares [mailto:amijar...@gmail.com] Sent: Thu 8/5/2010 12:24 PM To: Guojun Jin Cc: bug-follo...@freebsd.org; questi...@freebsd.org Subject: Re: Ifconfig (DHCP?) configures two IPs in one IF rl0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=8VLAN_MTU ether 00:40:f4:d1:23:9a inet 192.168.0.10 netmask 0xff00 broadcast 192.168.0.255 inet 10.10.50.126 netmask 0xff00 broadcast 10.10.50.255 media: Ethernet autoselect (100baseTX full-duplex) status: active plip0: flags=8810POINTOPOINT,SIMPLEX,MULTICAST metric 0 mtu 1500 I tried unplumb/delete rl0, but if does not work.
