not getting full name of last logged-in user in linux
Hi Everyone,
Thank you for your replies.
I try to identify the owner of a linux machine with login history. I used last unix command to get the list,parse and get the first username from the list. This is my assumption. But last command shows only 8 characters and i am looking for some other solution to my problem. Sorry for not explain this in my previous post.
Please let me know, is there any alternate way to find the owner (one of the login names) in linux machines.
I have this issue in Redhat 8+,Ubuntu-10.X and in Mandriva 2010 version

login.krb5
LOGIN(8) System Manager's Manual LOGIN(8)
NAME
login.krb5 - kerberos enhanced login program
SYNOPSIS
login.krb5 [-p] [-fFe username] [-r | -k | -K | -h hostname]
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 (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
-p preserve the current environment
-r hostname
pass hostname to rlogind. Must be the last argument.
-h hostname
pass hostname to telnetd, etc. Must be the last argument.
-f name
Perform pre-authenticated login, e.g., datakit, xterm, etc.; allows preauthenticated login as root.
-F name
Perform pre-authenticated login, e.g., 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.
krb_run_aklog
Attempt to run aklog. Default value false.
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.
