Open the /etc/hosts file with an editor of your choice, for instance use vi (AIX command to start vi
and open the file is
vi /etc/hosts
).
If you are not familiar with AIX editors, it may be easier to use
xedit
, an X-window based editor.
For the latter, you first need to start an X-session. Start the X-session with the AIX command
startx
(see
startx
manpages for details by issuing
man startx
). Then open the /etc/hosts file with
the AIX command
xedit /etc/hosts
, this will open a graphical editor session.
Scroll down to the appropriate line in the hosts file
Change all of the preconfigured addresses according to the table you have prepared in Step 1 -
Ob. Only change these addresses, do not change addresses not listed in the table above, or any
words in the /etc/hosts file. Change the addresses in all stanzas of the /etc/hosts file. That is, you
have to change five addresses.
