Solaris hostname

Setting the hostname - one of the most basic installation procedure. Unlike other operating systems a few places to visit. A few places to forget at least one of them.

Ex. setting the sunshine hostname on the machine with a bge0 interface and IP address 10.0.0.1

# echo -e "10.0.0.1\tsunshine" >> /etc/inet/hosts
# echo "sunshine" > /etc/hostname.bge0
# echo "sunshine" > /etc/nodename


There's one more file with the hostname and IP address information - /etc/inet/ipnodes. In Solaris 11 it's a symlink to /etc/inet/hosts file. So, you could leave it alone.

The change of the running system's name is as simple as:

# hostname sunshine
