Creating the alias with a /32 does not include the alias with ifconfig interface, however, as was suggested earlier. ifconfig -A is still required. Lee
Re: ifconfig problem - Botched upgrade?
Most definitely, -A is normally the only way to see alias info. Just wanted to let you know about the /32 mask for aliases. ???. Perhaps I missed some earlier context, but -A is not the only way to see alias info. $ ifconfig msk0 msk0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500 lladdr 00:16:cb:a7:52:1c groups: egress media: Ethernet autoselect (100baseTX full-duplex,rxpause,txpause) status: active inet 208.201.244.208 netmask 0xff00 broadcast 208.201.244.255 inet6 fe80::216:cbff:fea7:521c%msk0 prefixlen 64 scopeid 0x1 inet 208.201.244.210 netmask 0x broadcast 208.201.244.210 inet6 2001:5a8:4:910:216:cbff:fea7:521c prefixlen 64 $ Note the second line from the bottom. It is an alias as are the inet6 entries. Note the command line. -A was not given. Per the man page: -A Causes full interface alias information for each interface to be displayed. Shows all aliases on all interfaces. Not necessary (and not valid) if you only want to look at one interface. // marc

ifconfig problem - Botched upgrade?
In the process of upgrading a test machine from 3.9 - 4.0 - 4.1, something seems have to gotten farkled with ifconfig and/or network config. Can't find any clues in the upgrade docs. Is there something funky with 4.0 - 4.1? Could file permissions have gotten off-track somewhere? Symptoms; = ifconfig will not accept the base IP in hostname.fxp0, but neither can an alias be added after boot (ifconfig WILL, however, change the base IP for the i/f, which does work). History: == Did ithe upgrades by hand, as the machine will not boot from CD. 3.9 - 4.0 went just fine, .. no problems at all; 4.0 - 4.1 had this problem with an alias, so I did it a second time, just to make sure I didn't miss a step - no change. hostname.fxp0: # cat /etc/hostname.fxp0 inet 206.197.251.240 255.255.255.0 inet alias 206.197.251.204 255.255.255.0 ifconfig (after booting): = fxp0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500 lladdr 00:d0:b7:b6:3f:1b groups: egress media: Ethernet autoselect (100baseTX full-duplex) status: active inet6 fe80::2d0:b7ff:feb6:3f1b%fxp0 prefixlen 64 scopeid 0x1 inet 206.197.251.204 netmask 0xff00 broadcast 206.197.251.255 trying to add an alias: (tried variations w/wo inet, subnet mask, no difference) # ifconfig fxp0 inet alias 206.197.251.240 255.255.255.0 (no errors returned) # ifconfig lo0: flags=8049UP,LOOPBACK,RUNNING,MULTICAST mtu 33224 groups: lo inet 127.0.0.1 netmask 0xff00 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 fxp0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500 lladdr 00:d0:b7:b6:3f:1b groups: egress media: Ethernet autoselect (100baseTX full-duplex) status: active inet6 fe80::2d0:b7ff:feb6:3f1b%fxp0 prefixlen 64 scopeid 0x1 inet 206.197.251.204 netmask 0xff00 broadcast 206.197.251.255 (also tried rerunning netstart fxp0, no errors, no change) Either my mind is fried (possibly), or something has gotten falked through the upgrade process.
