D.2.4.2 Allowing Access When Using MIT-MAGIC-COOKIE-1

If you are using the MIT-MAGIC-COOKIE-1 authorization protocol, follow these steps to allow another user access to your server:

  1. On the machine running the server, use xauth to extract an entry corresponding to hostname:0 into a file.

    For this example, hostname is anyhost and the file is

    myhost% /usr/openwin/bin/xauth nextract - anyhost:0 > $HOME/

  2. Send the file containing the entry to the user requesting access (using Mail Tool, rcp or some other file transfer method).

    Note -

    Mailing the file containing your authorization information is a safer method than using rcp. If you do use rcp, do not place the file in a directory that is easily accessible by another user.

  3. The other user must merge the entry into his/her.Xauthority file.

    For this example, userhost merges into the other user's .Xauthority file:

    userhost% /usr/openwin/bin/xauth nmerge - <

    Note -

    The auth-data is session-specific; therefore, it is valid only as long as the server is not restarted.
