.SH DESCRIPTION
|
|
These administrative commands run only on the authentication server.
|
|
.IR Changeuser
|
|
manipulates an authentication database file system served by
|
|
.IR keyfs (4)
|
|
and used by file servers.
|
|
There are two authentication databases,
|
|
one holding information about Plan 9 accounts
|
|
and one holding SecureNet keys.
|
|
A
|
|
.I user
|
|
need not be installed in both databases
|
|
but must be installed in the Plan 9 database to connect to a Plan 9 service.
|
|
.PP
|
|
.I Changeuser
|
|
installs or changes
|
|
.I user
|
|
in an authentication database.
|
|
It does not install a user on a Plan 9 file server; see
|
|
.IR fs (8)
|
|
for that.
|
|
.PP
|
|
Option
|
|
.B -p
|
|
installs
|
|
.I user
|
|
in the Plan 9 database.
|
|
.I Changeuser
|
|
asks twice for a password for the new
|
|
.IR user .
|
|
If the responses do not match
|
|
or the password is too easy to guess
|
|
the
|
|
.I user
|
|
is not installed.
|
|
.I Changeuser
|
|
also asks for an APOP secret.
|
|
This secret is used in the APOP (RFC1939),
|
|
CRAM (RFC2195), and
|
|
Microsoft challenge/response protocols used for
|
|
POP3, IMAP, and VPN access.
|
|
.PP
|
|
Option
|
|
.B -n
|
|
installs
|
|
.I user
|
|
in the SecureNet database and prints out a key for the SecureNet box.
|
|
The key is chosen by
|
|
.IR changeuser .
|
|
.PP
|
|
If neither option
|
|
.B -p
|
|
or option
|
|
.B -n
|
|
is given,
|
|
.I changeuser
|
|
installs the
|
|
.I user
|
|
in the Plan 9 database.
|
|
.PP
|
|
.I Changeuser
|
|
prompts for
|
|
biographical information such as email address,
|
|
user name, sponsor and department number and
|
|
appends it to the file
|
|
.B /adm/netkeys.who
|
|
or
|
|
.BR /adm/keys.who .
|
|
.PP
|
|
.I Convkeys
|
|
re-encrypts the key file
|
|
.IR keyfile .
|
|
Re-encryption is performed in place.
|
|
Without the
|
|
.B -p
|
|
option
|
|
.I convkeys
|
|
uses the key stored in NVRAM
|
|
to decrypt the file, and encrypts it using the new key.
|
|
By default,
|
|
.I convkeys
|
|
prompts twice for the new password.
|
|
The
|
|
.B -p
|
|
forces
|
|
.I convkeys
|
|
to also prompt for the old password.
|
|
The
|
|
.B -a
|
|
option converts the file into AES format.
|
|
The format of
|
|
.I keyfile
|
|
is described in
|
|
.IR keyfs (4).
|
|
.PP
|
|
.I Printnetkey
|
|
displays the network key as it should be entered into the
|
|
hand-held Securenet box.
|
|
.PP
|
|
.I Status
|
|
is a shell script that prints out everything known about
|
|
a user and the user's key status.
|
|
.PP
|
|
.I Enable/disable
|
|
are shell scripts that enable/disable both the Plan 9 and
|
|
Netkey keys for individual users.
|
|
.PP
|
|
.I Authsrv
|
|
is the program, run only on the authentication server, that handles ticket requests
|
|
on TCP port 567.
|
|
It is started by an incoming call to the server
|
|
requesting a conversation ticket; its standard input and output
|
|
are the network connection.
|
|
.I Authsrv
|
|
executes the authentication server's end of the appropriate protocol as
|
|
described in
|
|
.IR authsrv (6).
|
|
The
|
|
.B -N
|
|
flag disables legacy bruteforceable DES-encrypted tickes as used by the
|
|
.B p9sk1
|
|
protocol, forcing the use of new
|
|
.B dp9ik
|
|
password authenticated key exchange.
|
|
.PP
|
|
.I Guard.srv
|
|
is similar. It is called whenever a foreign (e.g. Unix) system wants
|
|
to do a SecureNet challenge/response authentication.
|
|
.SS Anywhere commands
|
|
.PP
|
|
The remaining commands need not be run on an authentication server.
|
|
.PP
|
|
.I Debug
|
|
attempts to authenticate using each
|
|
.B dp9ik
|
|
and
|
|
.B p9sk1
|
|
key found in
|
|
.I factotum
|
|
and prints progress reports.
|
|
.PP
|
|
.I Wrkey
|
|
prompts for a machine key, host owner, and host domain and stores them in
|
|
local non-volatile RAM.
|
|
.PP
|
|
.I Login
|
|
allows a user to change his authenticated id to
|
|
.IR user .
|
|
.I Login
|
|
sets up a new namespace from
|
|
.BR /lib/namespace ,
|
|
starts a
|
|
.IR factotum (4)
|
|
under the new id and
|
|
.IR exec s
|
|
.IR rc (1)
|
|
under the new id.
|
|
.PP
|
|
.I Newns
|
|
sets up a new namespace from
|
|
.I namespace
|
|
(default
|
|
.BR /lib/namespace )
|
|
and
|
|
.IR exec s
|
|
its arguments.
|
|
If there are no arguments, it
|
|
.IR exec s
|
|
.BR /bin/rc .
|
|
Under
|
|
.BR -a ,
|
|
.I newns
|
|
adds to the current namespace instead of constructing a new one.
|
|
The
|
|
.BR -d
|
|
option enables debugging output.
|
|
.PP
|
|
.I None
|
|
sets up a new namespace from
|
|
.I namespace
|
|
(default
|
|
.BR /lib/namespace )
|
|
as the user
|
|
.I none
|
|
and
|
|
.IR exec s
|
|
its arguments under the new id.
|
|
If there are no arguments, it
|
|
.IR exec s
|
|
.BR /bin/rc .
|
|
It's an easy way to run a command as
|
|
.IR none .
|
|
.PP
|
|
.I As
|
|
executes
|
|
.I command
|
|
as
|
|
.IR user .
|
|
.I Command
|
|
is a single argument to
|
|
.IR rc ,
|
|
containing an arbitrary
|
|
.I rc
|
|
command.
|
|
This only works for the hostowner and only if
|
|
.L #¤/caphash
|
|
still exists.
|
|
