mkxauth(1x) Linux User's Manual mkxauth(1x) NAME
mkxauth - create and merge .Xauthority files SYNOPSIS(1) mkxauth [ -q ] [ -u login ] -c [ host [ host ... ] ] (2) mkxauth [ -q ] [ -u login ] -m login(3) mkxauth [ -q ] [ -u login ] -f host(4) mkxauth [ -q ] [ -u login ] -r host [ -l login ] (5) mkxauth [ -q ] [ -u login ] -z host [ -l login ] DESCRIPTION
mkxauth aids in the creation and maintenance of X authentication databases (.Xauthority files). Use it to create a ~/.Xauthority file or merge keys from another local or remote .Xauthority file. Remote .Xauthority files can be retrieved via FTP (using ncftp(1)) or via rsh(1). For a slight measure of security, mkxauth does not create any temporary files containing authentication keys (although anyone spy- ing on network packets can see the authentication key data as they pass through the network; for secure network communications, use ssh(1)). Creating and Adding to a .Xauthority File To create a .Xauthority file, use mkxauth -c (see(1) above). mkxauth creates a .Xauthority file in the user's home directory (~/), con- taining a `key' or `magic cookie' for the host it was run on (the one returned by hostname(1)). If a .Xauthority file already exists, the keys are added to it. If keys for that host already exist, they are replaced. To create or add to a .Xauthority file for another user, use mkxauth -u login -c. mkxauth adds keys to ~login/.Xauthority (only the root user is allowed to do this). To add a key for more than one host, specify all hosts on the command line: mkxauth -c daffy porky bugs. All hosts specified on the same command line receive the same key. To create different keys for multiple hosts, run mkxauth for each host in succession: mkxauth -c daffy mkxauth -c porky mkxauth -c bugs Merging Keys from Local .Xauthority Files To merge keys from another local user's .Xauthority file, use mkxauth -m login (see(2) above). mkxauth adds the keys in ~login/.Xauthor- ity to ~/.Xauthority, replacing any keys which already exist. ~login/.Xauthority must be readable by the user running mkxauth (normally only the root user can read other people's .Xauthority files). Merging Keys via FTP To merge keys from a remote .Xauthority file via FTP, use mkxauth -f host (see(3) above). mkxauth retrieves the remote .Xauthority from host using ncftp(1) and adds those keys to ~/.Xauthority, replacing any keys which already exist. [NOTE: you must have a ~/.netrc file set up to automatically log you into host, otherwise the FTP login attempt will fail.] Merging Keys via rsh(1) To merge keys from remote .Xauthority file via rsh(1), use mkxauth -r host (see(4) above). mkxauth retrieves the remote .Xauthority from host using rsh(1) and adds those keys to ~/.Xauthority, replacing any keys which already exist. To login as a different user, use -l login. [NOTE: you must have a .rhosts file set up properly for this to work, otherwise the remote login attempt will fail]. Merging Keys via rsh(1) and gzip(1) If your remote .Xauthority file is large, or to make it slightly less obvious that you're transferring authentication keys over the net- work, mkxauth can gzip(1) your .Xauthority file before retrieving it via rsh(1). To do this, use mkxauth -z host (see(5) above). mkxauth retrieves the remote .Xauthority from host using rsh(1) and adds those keys to ~/.Xauthority, replacing any keys which already exist. To login as a different user, use -l login. [NOTE: you must have a .rhosts file set up properly for this to work, otherwise the remote login attempt will fail]. Options To make mkxauth operate quietly, use the -q option. To add to ~login/.Xauthority, use the -u login option. To use login for the remote login in mkxauth -f, mkxauth -r, and mkxauth -z, use the -l login option. Getting Help To get quick help about mkxauth, use mkxauth --help. FILES
~/.Xauthority ~/.netrc ~/.rhosts COMMENTS
mkxauth is mostly useful for maintaining .Xauthority files in an environment which uses startx(1x). xdm(1x) uses its own method of gener- ating .Xauthority files. However, mkxauth is still useful for transferring .Xauthority information to remote login sessions so that the user can display remote X clients on the local host without too much trouble. Note, however, that using rsh(1) is inherently insecure, and sites concerned about security should use ssh(1) instead (see http://www.cs.hut.fi/ssh/ for more information). SEE ALSO
