For #2 (maybe a long shot):
Just recently I needed to change on the fly the IP address of one
machine, and after a /etc/rc.d/netif restart, I lost Internet
connectivity. Access to the local network was normal. This machine is
behind an ADSL router (IP 192.168.0.250) which acts as the gateway. The
problem was, after the IP address change the default gateway was lost.
defaultrouter was present in rc.conf but was not applied again after the
netif restart. A quick route add default 192.168.0.250 fixed it.

Check your default gateway when switching from DHCP to static. IIRC a
/etc/rc.d/netif stop/start will recreate the default route.

Not as I recall though. You will need to do a /etc/rc.d/routing restart
if your default router changes. The only time you might not need it is
when your routes are setup via DHCP.

Correction: netif start/stop will _NOT_ recreate the default route... it
was a bit early for me :-)

That sounds like it's probably what I need.  Thank you!

To clarify: I have several commonly-used network configs in my
/etc/rc.config file, and often change which one I have commented out
there, then restart with:

  # /etc/rc.d/netif restart

With the revelation that /etc/rc.d/routing needs a restart, I think that
probably solves the problem.

late filesystems and switching net configs

2007-07-03 Thread Chad Perrin
I have a couple of niggling little, er, quirks that I'd like to get
sorted out on my FreeBSD Thinkpad.

  1. During boot, if I'm booting up anywhere but at home (where my static
  IP address configuration applies), the startup messages pause for a few
  long seconds at a message that says Mounting late filesystems.  When
  plugged into the network at home, though, using my static IP
  configuration, it swoops past that pretty quickly.  Can someone tell me
  what that's about?

  2. For some reason, if I use DHCP at all then want to switch back to my
