       clog - Authenticate to the Coda distributed file	system

       clog  [	-pipe  ]  [  -test ] [ -host hostname ]	[ -coda	| -kerberos4 |
       -kerberos5 ] [ -tofile file ] [ -fromfile file ]	[username][@realm]

       This command enables users to get tokens	to use for authenticated  com-
       munication  with	 a Coda	File System.  The given	name and a password or
       kerberos	token are passed to an Authentication Server. The  Authentica-
       tion Server returns a set of tokens encoding the	chosen identity	if the
       password	is correct.  clog passes these tokens to  the  venus  process,
       which  acts as the users	agent for file manipulation. These tokens have
       a limited lifetime, becoming invalid after 25 hours. If an  attempt  is
       made  to	operate	on a Coda File System object while the user is not au-
       thenticated, the	user will assume the privileges	of the Anonymous user.

       clog accepts the	following arguments:

       -pipe  For use in shell scripts,	the password is	read from stdin.  This
	      option is	also enabled when stdin	is not a tty.

       -test  Test the clog-venus token	passing	code.

       -host  Specify the host where the authentication	server is running.

       -coda | -kerberos4 | -kerberos5
	      Authentication  mechanism, use kerberos tickets or coda password
	      to identify yourself to the authentication server.

	      After obtaining a	token from the authentication server, write it
	      to a file.

	      Instead  of connecting to	the authentication server, read	a pre-
	      viously saved token from a file and pass it to venus.

	      Coda user	name you wish to be identified as within the specified
	      realm.  If  the username is not specified, clog tries to use the
	      local login name.	If the Coda realm name is not  specified  clog
	      falls  back  to using the	default	realm name as specified	in the
	      venus.conf configuration file.

       o The on-disk tokens are	not encrypted.

       o The -pipe option should be dropped, there already is an isatty(stdin)
	 test which is sufficient for most cases.

       o The -test option should also test the reading and writing code	of to-
	 ken files.
