Yea, uxb3 is the hostname(uxb3.wiu.edu). I know it is Unix. I can access the school's Unix server from anywhere using any computer with the program Putty <PuTTY Download Page> .... which I then log in to "toolman"(which is also the hostname) using command "ssh toolman.wiu.edu" and can log in with my username/password for the school's system. I do not know if

Code:

 uname -a

works on any of the systems. I can get back to you with some betters answers about the actual systems by Monday when I can ask someone at the university's IT dept.

Nevermind, I made a typo here:

Quote:

printf("%s!\n", argv[1]);

In which, I forgot to type '\' after the exclamation point. Problem solved.

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.
