Hi,

You have to cahnge 3 different files.
1. /etc/hosts
2. /etc/nodename
3. /etc/hostname.(interface)

To find out which network interface you are using you ust use the ifconfig -a command and it will print the network information.

The safest way is probably to use the sys-unconfig script. Here's a good reference: thread60-382954

As Annihilannic stated, the easiest way is to run the sys-unconfig script. It will walk you through all the necessary network and node information. You will not destroy any data.

RUN sys-unconfig£¬then reset,input your new hostname

Hi contec17 and race123,

i have executed sys-unconfig, but the problem is when i select DHCP it doesn't ask me for hostname.

 

[Annihilannic]

Because a hostname is usually associated with an IP address, and DHCP by definition means that the IP address is dynamic, I presume that's normal!

Presumably it needs to be configured on the DHCP server and/or in the client's /etc/hosts file or DNS.

I'm guessing!

Thanks Annihilannic and all other guys who tried to help me. I think it is becuase i have selected DHCP.

Thanks again.

Hi AmolBrid,

Back in Solaris7, in order to use dhcp and get around the system being renamed 'unknown' if your dhcp server did not supply a name, we used to 'comment' or remove the following lines in the /etc/init.d/inetsvc file:

hostname=`/sbin/dhcpinfo Hostname`
if [ -z "$hostname" ]; then
hostname="unknown"
fi
-----------------------------------------------------------
Or, you could just change:
hostname ="unknown"
to
hostname =&quot;<your hostname>&quot;
-----------------------------------------------------------
Then reboot again.

This assumes that you have the proper entries in:
/etc/hosts
/etc/hostname.<interface> (ex: /etc/hostname.hme0)
/etc/nodename

I'm pretty sure this also worked in Solaris 8.

If that doesn't work, try this web site for a diff approach:

Hope this helps...

I've got Solaris 9 (i86 flavour) and found that you have to change the /etc/init.d/network file as this appears to set the hostname first. I did try updating inetsvc but that didn't work.

case &quot;$_INIT_NET_STRATEGY&quot; in
&quot;dhcp&quot hostname=&quot;<your hostname>&quot; ;;
