left 1 interface after rebooting..(sun platform)

[Simon shaw]

Hi.. I tried to configure 3 interfaces on my sun servers, originally, the 
first interface (eri0) is our LAN IP. Second interface is with 0.0.0.0 IP, 
and third interface (eri1) doesn't show up. as shown below

lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
eri0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 50.100.165.55 netmask fffffc00 broadcast 50.100.167.255
ether 0:3:ba:27:52:97
qfe0: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 0.0.0.0 netmask 0
ether 0:3:ba:27:52:97

After that I configured qfe0 (second interface) with ifconfig for a IP and 
used ifconfig eri1 plump to make it third interface show up and configure a 
IP.
But after rebooting, everything goes back to original. Second interface with 
0.0.0.0 IP and third interface missing as shown above. Why?? What should I 
do to make it stay.

Sun boxes generally run Solaris which I'm assuming is what your using 
from what you've said. I guess this is sort of OT but I've answered your 
question anyhow. For the best Solaris information check out 
http://docs.sun.com/

You need to create /etc/hostname.qfe1 (or whatever) containing the 
hostname the interface should be brought up with. Put hostname to ip 
mapping in /etc/hosts and netmask in /etc/netmasks

eg:
/etc/hostname.qfe1
mybox-30

/etc/hostname.qfe2
mybox-56

/etc/hosts
192.168.56.2	mybox-56
192.168.30.6	mybox-30

/etc/netmasks
192.168.0.0 255.255.255.0
