NAME

       drawterm  - connection to cpu, fs, and auth servers

SYNOPSIS

       drawterm  [  -GBO  ] [ -h host ] [ -u user ] [ -a authserver ] [ -s secstore ] [ -e 'crypt
       hash' ] [ -k keypattern ] [ -p ] [ -t timeout ] [ -r root ] [ -g geometry ] [ -c cmd ...]

DESCRIPTION

       Drawterm is a client for connecting venerable systems to  Plan  9  systems.  The  standard
       behavior  with no options provided is to begin a graphical session which will prompt for a
       cpu server, auth server, and password. If $USER is not set, drawterm  will  prompt  for  a
       username as well.

       The  goal  of drawterm is to provide an abstraction layer from the client operating system
       to the desired Plan 9 system. Client-side devices that can be represented  as  filesystems
       will be and are served from the namespace drawterm operates in. Generally, this means that
       drawterm behaves like a Plan 9 kernel and will attempt to reconstruct a Plan  9  terminal-
       like experience from a non-Plan 9 system.

       The options are:

       -G     Start drawterm in text-only mode (no graphics).

       -B     Disable kbdfs.

       -O     Use the old cpu(1) to connect to the cpu server rather than rcpu(1).

       -h host
              Connect to host for cpu.

       -u user
              Remote user id.

       -a authserver
              Connect to authserver for auth.

       -s secstore
              Sets the address of the secstore(8) server. If the -s option is absent, secstore(1)
              will attempt to dial tcp!$auth!secstore (or the otherwise specified auth server).

       -e 'crypt hash'
              Specifies the 'crypt hash' for the connection. The default is 'rc4_256 sha1'. Usage
              of     no     encryption     can     be     specified    by    'clear'    as    per
              ssl(3).Notethatthisoptionisdeprecatedandonlyrelevanttotheoutdated cpu(1) protocol.

       -k keypattern
              Use keypattern to select a key to authenticate to the remote side (see auth(2)).

       -p     Protect the connection against connection resets by establishing aan(8) tunnel.

       -t timeout
              Set the timeout for aan(8) to a value in seconds (default is one day).

       -r root
              Specifies the root directory on the client. The default is /root  and  all  further
              paths are relative thereto.

       -c cmd ...
              The command to run can be passed with -c cmd ..., otherwise an interactive shell is
              started. The user's profile is run before the command with $service set to  cpu  to
              allow further customization of the environment (see rc(1) for more information).

ENVIRONMENT VARIABLES

       USER   Unless otherwise specified, the user stored in $USER is used for authentication.

       PASS   If  $PASS  is  set,  no  password  will  be  prompted for in authentication and the
              contents of $PASS will be used instead.

       cpu    Unless otherwise specified, the address stored in $cpu  is  used  for  the  rcpu(1)
              connection (if set).

       auth   Unless  otherwise  specified,  the  address stored in $auth is used for the rcpu(1)
              connection (if set).

SERVICES

       A number of services are provided in drawterm. The exact functionality and availability of
       certain features may be dependent on your platform or architecture:

       /mnt/term
              A  mount  of  the  client  machine's  root  filesystem  as  well as certain virtual
              filesystems to present Plan 9 devices and interfaces that are not available on non-
              Plan  9  systems.  On Windows this is a directory containing the available lettered
              disks (C:, A:, etc.). Additionally, there is always a /mnt/term/root  folder  which
              is  a copy of the client machine's namespace with no virtual filesystems present as
              to avoid conflicting names (such as with Linux's /root).

       #b     Assuming the -B flag is not set, /dev/kbd will be provided for kbdfs (see kbd(3)).

       #i     Assuming the -G flag is not set, various drawing device files will be  provided  in
              /dev (see draw(3)).

       #m     Assuming  the  -G flag is not set, files for controlling the mouse will provided in
              /dev (see mouse(3)).

       #c     A number  of  console  device  files  giving  access  to  the  console  screen  and
              miscellaneous information are provided and mounted in /dev (see cons(3)).

       #I     The  network  filesystem  is served and bound over /net, providing the interface to
              Internet Protocol stacks (see ip(3)).

       #A     An audio device filesystem is served, if possible, as a one-level directory in /dev
              (see  audio(3)).   Note  that this device, if unable to be served, will not cause a
              panic in drawterm.

EXAMPLES

       Make a headless rcpu session connecting to 10.30.167.25 using plan9.postnix.us as the auth
       server with aan(8) enabled:

              drawterm -G -h 10.30.167.25 -a plan9.postnix.us -p

       Make  a  session using cpu rather than rcpu to tenshi.postnix.us; this command is the same
       for connecting to a Plan 9 4th edition system:

              drawterm -O -h tenshi.postnix.us

BUGS

       Drawterm is not a Plan 9 program.

HISTORY

       Drawterm was originally developed by Russ Cox (rsc) for Plan 9 4th edition. This  original
       version  is  still usable on Plan 9 and its forks which use the p9sk1 and older authsrv(6)
       protocols.  https://swtch.com/drawterm/

       The 9front  project  has  forked  drawterm  to  incorporate  features  from  9front,  most
       importantly  dp9ik  authentication  support  (see  authsrv(6))  and  the TLS-based rcpu(1)
       protocol.
