Default problem with static v4 IPs

Please excuse the fact that I'm probably overlooking something really obvious and trivial but I'm stuck.

I have some OpenBSD background but have not worked with it for a number of years. I recently decided to use OpenBSD (4.6) and pf to build a new firewall that I need.

Initially I set both network interfaces to dhcp in their hostname.if files (hostname.fxp0 & hostname.fxp1) just to make sure all the hardware was working correctly. Everything worked perfectly.

I then changed the hostname.if files to set static IPs as follows:

hostname.fxp1
Code:
inet w.x.y.z 255.255.255.0 w.x.y.255 description internal
where w.x.y.z is the actual IP (of course).

But when I bring the interface up, I get this result:
Code:
fxp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         lladdr 00:02:be:28:52:33
         priority: 0
         media: Ethernet autoselect (100BaseTX full-duplex)
         status: active
         inet6 fe80::202:b3ff:fe28:5233%fxp1 prefixlen 64 scopeid 0x2
and, indeed, I don't seem to have any valid IPv4 address.

I checked all the man pages but didn't find anything that illuminated me.

Can someone tell me what I'm missing here?

Remove "description internal" from the file. Neither of these two words are valid options for fxp(4) media.

thanks for the suggestion but it had no effect. I still don't get an IPv4 address.

If you simply took the interface down, changed its configuration, & then brought it back up, this is insufficient to re-read the hostname.if(5) file & reinitialize the interface. What you need is netstart(8) which is executed (as root) by:

# sh /etc/netstart

Re-reading Section 6.2 of the FAQ is also warranted.

BTW, I don't have any trouble bringing up the interface manually.
ifconfig fxp1 inet w.x.y.z netmask 255.255.255.0 -inet6
does exactly what I need. But I don't seem to be able to configure hostname.fxp1 correctly to do the same thing automatically.

What are the permissions on /etc/hostname.fxp1?

Thanks. Got it.

Curiously, now my original syntax also works and it sets the description properly.

I agree, I also failed to understand the problem.. description is however, a valid "interface-independent" option jggimi.

It's actually used as an example in hostname.if(5).

I had intended to do exactly that, ocicat, but then I discovered that my original syntax is now working perfectly so I'm more than a little confused and, unfortunately, can't say anything particularly enlightening.
