NAME
dos - command line access to Microsoft Windows™ servers
SYNOPSIS
dos [ -h host ] [ -u user ] [ -k keypattern ] [ -c cmd args
... ]
DESCRIPTION
Dos connects to a Windows host and starts a session to
cmd.exe on host, or the machine named in the $dos environ-
ment variable if there is no -h option.
The user name and authentication domain is usually picked up
from factotum(4), the entry is selected based on the default
domain of the remote host. An alternative userid may be
specified with -u. Userids have the form user@authdom where
authdom is the windows authentication domain.
If a -c is present, the remainder of the command line is
executed by rc on the server, and then dos exits.
The remote shell's initial working directory is set to the
current directory when dos was envoked, translated by map-
pings defined by the dosmap(6) configuration files. Rio's
/dev/wdir is kept in sync with directory changes on the
remote server providing (where possible) the correct context
for the plumber.
On connection the users Roving Profile and user specific
environment are loaded, vestigial network mounts left over
from the GUI environment are deleted and replaced with
shares defined in the configuration files.

BUGS
Interrupts are neither caught nor passed to the remote host.
DOS(1) DOS(1)
The remote shell's standard input, output and error are
attached to the dos commands file descriptors rather
/dev/cons.
There should be no need to duplicate the dosmap file on both
local and remote hosts.
The network link is not encrypted, thus all usernames and
passwords are vunerable to sniffing.
Detection of the current directory (parsing the windows
prompt) is horrific.
The Dos client should be replaced by cpu(1), with an addi-
tional tlspass authentication mechnism. Dosd.exe should be
replaced by cpud.exe a 9p client which opens
/mnt/term/dev/cons for console I/O, /mnt/term/dev/cpunote
for interrupts, /mnt/term/dev/wdir to keep the plan9 working
directory synchronised with windows directory changes, and
/mnt/term/usr/$user/lib/dosmap to discover shared drive map-
pings.
