change hostname - solaris vs linux

in order to change your machine's hostname, you will need to edit some files.

for solaris:
there are 6 files you need to edit:

/etc/hosts
/etc/nodename
/etc/hostname.network_interface (e.g hostname.hme0)
/etc/net/*/hosts (3 hosts files)

but for linux:
only 1 file

/etc/sysconfig/network

for temporary hostname (i'm not sure why you need it temporary), you can use command:

hostname new_hostname

but if you want it permanent, you need to reboot the system after changing all the necessary files.
