Not sure on AIX but on linux you can do:

Code:
PS1="\H/#"



Where:
Code:
       \a     an ASCII bell character (07)
       \d     the  date  in  "Weekday  Month  Date" format
              (e.g., "Tue May 26")
       \e     an ASCII escape character (033)
       \h     the hostname up to the first `.'
       \H     the hostname
       \n     newline
       \r     carriage return
       \s     the name of the shell, the  basename  of  $0
              (the portion following the final slash)
       \t     the current time in 24-hour HH:MM:SS format
       \T     the current time in 12-hour HH:MM:SS format
       \@     the current time in 12-hour am/pm format
       \u     the username of the current user
       \v     the version of bash (e.g., 2.00)
       \V     the  release  of  bash, version + patchlevel
              (e.g., 2.00.0)
       \w     the current working directory
       \W     the basename of the current  working  direc-
              tory
       \!     the history number of this command
       \#     the command number of this command
       \$     if  the effective UID is 0, a #, otherwise a
              $
       \nnn   the character  corresponding  to  the  octal
              number nnn
       \\     a backslash
       \[     begin a sequence of non-printing characters,
              which could be used to embed a terminal con-
              trol sequence into the prompt
       \]     end a sequence of non-printing characters

NAME
login.krb5 - kerberos enhanced login program SYNOPSIS
login.krb5 [ -fF [username] ] DESCRIPTION
login.krb5 is a modification of the BSD login program which is used for two functions. It is the sub-process used by krlogind and telnetd to initiate a user session and it is a replacement for the command-line login program which, when invoked with a password, acquires Ker- beros tickets for the user. login.krb5 will prompt for a username, or take one on the command line, as login.krb5 username and will then prompt for a password. This password will be used to acquire Kerberos Version 5 tickets and Kerberos Version 4 tickets (if possible.) It will also attempt to run aklog to get AFS tokens for the user. The version 5 tickets will be tested against a local krb5.keytab if it is available, in order to verify the tickets, before letting the user in. However, if the password matches the entry in /etc/passwd the user will be unconditionally allowed (permitting use of the machine in case of network failure.) OPTIONS
-r hostname pass hostname to rlogind. -h hostname pass hostname to telnetd, etc. -f name Perform pre-authenticated login, e.g., datakit, xterm, etc.; allow preauthenticated login as root. -F name Perform pre-authenticated login, e.g.,for datakit, xterm, etc.; allows preauthenticated login as root. -e name Perform pre-authenticated, encrypted login. Must do term negotiation. CONFIGURATION
login.krb5 is also configured via krb5.conf using the login stanza. A collection of options dealing with initial authentication are pro- vided: krb5_get_tickets Use password to get V5 tickets. Default value true. krb4_get_tickets Use password to get V4 tickets. Default value true. krb4_convert Use Kerberos conversion daemon to get V4 tickets. Default value false. If false, and krb4_get_tickets is true, then login will get the V5 tickets directly using the Kerberos V4 protocol directly. This does not currently work with non MIT-V4 salt types (such as the AFS3 salt type.) Note that if configuration parameter is true, and the krb524d is not running, login will hang for approxi- mately a minute under Solaris, due to a Solaris socket emulation bug. krb_run_aklog Attempt to run aklog. Default value true. aklog_path Where to find it [not yet implemented.] Default value $(prefix)/bin/aklog. accept_passwd Don't accept plaintext passwords [not yet implemented]. Default value false. DIAGNOSTICS
All diagnostic messages are returned on the connection or tty associated with stderr. SEE ALSO
rlogind(8C), rlogin(1C), telnetd(8c) BUGS
Should use a config file to select use of V5, V4, and AFS, as well as policy for startup. LOGIN(8C)
