configure interface as down during startup
Hi,
I have struggled now for a while with the interface configuration on Solaris 10. I want to configure a logical interface with IP address and netmask, but not have it set to "up". I merely want to prepare it for failover, handled by a seperate program.
After finding out that the startup script will overrule some of my commands in the /etc/hostname.* file if I only have one line, I added a second one with the "addif" statement to add the virtual interface and set it explicitly to down. That still does not work though, because this line in the "net-physical" script:
# Configure the rest of the IPv4 interfaces automatically, quietly.
/sbin/ifconfig -adD4 auto-revarp netmask + broadcast + up
will bring all interfaces up. The only workaround I found, is to comment out that line (I don't have any other interfaces which would require that one). I cannot believe that this is the only way to achieve what I want. So maybe somebody could help me out what I am missing....?
Thanks,
iMax

Where do you see that line? In my copy that is in a conditional that is true only when the hostname is not set. Whatever is going on shouldn't be in that line.
In addition, I can't find that comment in my script.
# grep quiet /lib/svc/method/net-physical
#
Perhaps your release has some changes?
I just made the following change to my test machine.
# echo >> /etc/hostname.hme0
# wc -l /etc/hostname.hme0
2 /etc/hostname.hme0
# init 6
[wait for reboot]
[ login ]
# ifconfig hme0 | grep RUN
hme0: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
#
Not up. Further inspection will reveal that broadcast/netmask is also not configured, so you'd need to do that as well.

Hi Darren,
Thanks for looking into this.
My install version is 3/05, but I have installed some recommended patch clusters. Kernel patch level is 125101-03.
grep -n quiet /lib/svc/method/net-physical
271:# Configure the rest of the IPv4 interfaces automatically, quietly.
The header of the script shows the following:
# ident "@(#)net-physical1.2304/11/19 SMI"
I have now quickly looked at a production server here with the 11/06 release and that one has version 1.25 of the net-physical script, with the changes you described. That probably means I just have to find out which patch I need to apply... ;-)
Regards,
