Can someone tell me how to tell the machine (solaris 8) what the
hostname is when it uses DHCP? I put "flare" in /etc/hostname.elxl0
but it still comes up with hostname "unknown". Can someone also tell
me how to disable DHCP and hard-code the IP after a system has been
installed with DHCP on?

Here is the info doc from sun on this. It worked for me:

1. For Solaris 2.6 and Solaris 7 Systems.

Edit the file /etc/init.d/rootusr and change the line that reads

hostname=`/sbin/dhcpinfo Hostname`

to

# hostname=`/sbin/dhcpinfo Hostname`
hostname=`shcat /etc/nodename`
uname -S $hostname

Save the file and reboot the system. The system's hostname will be the
entry in the file /etc/nodename.

2. For Solaris 8 systems.

Edit the file /etc/init.d/network and change the line that reads

"dhcp") hostname=`/sbin/dhcpinfo Hostname` ;;

to

# "dhcp") hostname=`/sbin/dhcpinfo Hostname` ;;
"dhcp") hostname=`shcat /etc/nodename` ;;

Then, edit the file /etc/init.d/inetsvc and change the line that reads

hostname=`/sbin/dhcpinfo Hostname`

to

# hostname=`/sbin/dhcpinfo Hostname`
hostname=`/usr/bin/cat /etc/nodename`

Save the files and reboot the system. The system's hostname will be the
entry in the file /etc/nodename.

This has been answered numerous times in this group. Here's a search
on Google's Usenet archive that gives several answers:

"ifconfig elxl0 dhcp drop" to turn it off right now.

"rm /etc/dhcp.elxl0" to make it not turn on at next boot.

OK, if I remove the /etc/dhcp.elxl0 file, how do I tell it what IP to
use at startup next time?

Thanks!

You put it in /etc/hostname.elxl0. Or, you put the hostname in
/etc/hostname.elxl0 and an entry matching up that hostname and IP
address in /etc/hosts.

You probably also want to know about /etc/defaultrouter, and maybe
/etc/nsswitch.conf and /etc/resolv.conf, if you don't already know
about those. "man defaultrouter" "man nsswitch.conf", and "man resolv.conf"
will get you information on those.

I already knew about everything but the default router file. Thanks.
That's great.

As for the /etc/hostname.elxl0... What do I put in that file? Right
now it's empty. If I do man hostname it of course gives me the
manpage for /usr/bin/hostname.

Thanks!
