Before connecting to the server, the client must log
in with the command cvs login. Logging in
verifies a password with the server, and also records
the password for later transactions with the server.
The cvs login command needs to know the
username, server hostname, and full repository path,
and it gets this information from the repository
argument or the CVSROOT environment variable.
cvs login is interactive -- it prompts for a
password:
cvs -d :pserver:bach@chainsaw.brickyard.com:/usr/local/cvsroot login CVS password:
The password is checked with the server; if it is
correct, the login succeeds, else it fails,
complaining that the password was incorrect.
Once you have logged in, you can force CVS to connect directly to the server and authenticate with the stored password:
cvs -d :pserver:bach@chainsaw.brickyard.com:/usr/local/cvsroot checkout foo
The `:pserver:' is necessary because without it,
CVS will assume it should use rsh to
connect with the server (see section Connecting with rsh).
(Once you have a working copy checked out and are
running CVS commands from within it, there is no
longer any need to specify the repository explicitly,
because CVS records it in the working copy's
`CVS' subdirectory.)
Passwords are stored by default in the file `$HOME/.cvspass'. Its format is human-readable, but don't edit it unless you know what you are doing. The passwords are not stored in cleartext, but are trivially encoded to protect them from "innocent" compromise (i.e., inadvertently being seen by a system administrator who happens to look at that file).
The CVS_PASSFILE environment variable overrides
this default. If you use this variable, make sure you
set it before cvs login is run. If you
were to set it after running cvs login, then
later CVS commands would be unable to look up the
password for transmission to the server.
The CVS_PASSWORD environment variable overrides
all stored passwords. If it is set, CVS
will use it for all password-authenticated
connections.
