NAME

clog - Authenticate to the Coda distributed file system

SYNOPSIS

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

DESCRIPTION

This command enables users to get tokens to use for authenticated communication with a Coda File System. The given name and a password or kerberos token are passed to an Authentication Server. The Authentication 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 authenticated, 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.
-tofile
After obtaining a token from the authentication server, write it to a file.
-fromfile
Instead of connecting to the authentication server, read a previously saved token from a file and pass it to venus.
[username][@realm]
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.

BUGS

*
The on-disk tokens are not encrypted.
*
The -pipe option should be dropped, there already is an isatty(stdin) test which is sufficient for most cases.
*
The -test option should also test the reading and writing code of token files.
