Starting a second loopback interface and services at startup

2004-05-28 Thread Robert Lowe
Hi!
New to FreeBSD and running 5.2.1-RELEASE on an Alpha.  I do predominantly
SysV/ATT boxes, so I feel a bit out of it...
Question #1:
I need to create a second loopback interface, which I can do just fine
at the command line:
# ifconfig lo1 create
# ifconfig lo1 inet a.b.c.d netmask x.x.x.x
How do I automate this at startup?  I stumbled across something in
/etc/network.subr that suggests I ought to create /etc/start_if.lo1
which would then be sourced.  I assume I can add a ifconfig_lo1
variable to /etc/rc.conf.  I tried these, but with no luck.  Can
anyone point the way?
Question #2:
I'm trying to start Quagga services on this box (zebra and ospfd).
I added scripts to /usr/local/etc/rc.d/ for these two, but no luck.
They work fine from the command line, e.g.
# /usr/local/etc/rc.d/zebra.sh start
# /usr/local/etc/rc.d/ospfd.sh start
Both have the .sh extension, which seems to be required.  How should
I troubleshoot this?  I don't find anything in dmesg.today suggesting
that there was even an attempt to run the scripts.  Also, can one use
the rcorder keywords to provide startup ordering for scripts in
/usr/local/etc/rc.d ???
TIA,
Robert

I figured out the correct way to do this:
1. Override the default network_interfaces variable in
   /etc/defaults/rc.conf in /etc/rc.conf.  This is a space-separated
   list of interfaces to start.  I included the new loopback interface
   to create.
2. Create a /etc/start_if.if-name script to create the interface.
3. Add a ifconfig_if variable to rc.conf as well.  I had this already,
   so I did not have to do anything.
The reason the last two steps did nothing before was the list of
interfaces in the netif script is generated using 'ifconfig -l',
which of course does not include interfaces which haven't yet been
created, and so the start_if.if-name script is not run.

The scripts now run properly, but in the wrong order, so I still need
an answer here.  They seem to execute in alpha-numeric order.  I suppose
I could start them in one script, but that's not really the answer.  Help!
I suppose I could use the Snnname SysV approach.  ;-)
