.SH DESCRIPTION
|
|
.B xlock
|
|
locks the X server till the user enters their password at the keyboard.
|
|
While
|
|
.B xlock
|
|
is running,
|
|
all new server connections are refused.
|
|
The screen saver is disabled.
|
|
The mouse cursor is turned off.
|
|
The screen is blanked and a changing pattern is put on the screen.
|
|
If a key or a mouse button is pressed then the user is prompted for the
|
|
password of the user who started
|
|
.BR xlock .
|
|
|
|
If the correct password is typed, then the screen is unlocked and the X
|
|
server is restored. When typing the password Control-U and Control-H are
|
|
active as kill and erase respectively. To return to the locked screen,
|
|
click in the small icon version of the changing pattern.
|
|
|
|
In the lower part of the password screen a text is displayed. This
|
|
message is taken from the first file of the following that exists:
|
|
$HOME/.xlocktext, $HOME/.plan, or $HOME/.signature.
|
|
|
|
On systems which support new BSD style authentication, the password
|
|
may be prefixed by an authentication style followed by a colon
|
|
(i.e. "style:password"). See the login.conf(5) for more information
|
|
on authentication styles.
|
|
|
|
.SH "NOTE ON ETIQUETTE"
|
|
.I Xlock
|
|
should not be used on public terminals when there is a high demand for them.
|
|
|
|
If you find a public terminal that has been locked by another user and
|
|
there are no other terminals available, and the terminal appears to have
|
|
been left idle for a while (normally more than 15 minutes), it is fair to
|
|
try to reset the session in some manner.
|
|
|

.BI \-delay \ usecs
|
|
The

.I delay
|

option sets the speed at which a mode will operate. It simply sets the
|
|
number of microseconds to delay between batches of animations. In
|
|
blank mode, it is important to set this to some small number of seconds,
|
|
because the keyboard and mouse are only checked after each delay, so you
|
|
cannot set the delay too high, but a delay of zero would needlessly

consume cpu checking for mouse and keyboard input in a tight loop, since

blank mode has no work to do.

|
|
In atunnels, fire, gears, sballs and sproingies it is the size of the screen
|
|
(default 400), this is because on many slow systems it runs too slow when the

0 is grayscale and 1 is very rich color. 0.4 is a nice pastel.

is now similar to the option

but losira. Use a "+" or a "," to add modes like "spiral+venetian".
|
|
.TP 5
|
|
.BI \-erasedelay \ usecs
|
|
The

.I erasedelay

option sets the number of microseconds for steps of the

|
|
(a setting of 0 and the
|

|
is bypassed).
|
|
.TP 5
|

.B +/-nolock
|
|
The

.I nolock

.B xlock
|
|
to only draw the patterns and not lock the display.
|
|
A key press or a mouse click will terminate the screen saver.
|

.TP 5

.B -/+inwindow
|
|
Runs
|
|
.B xlock

in a window, so that you can iconify, move, or resize it and

still use your screen for other stuff. When running in a window,
|
|
.B xlock
|
|
no longer locks your screen, it just looks good.
|
|
.TP 5

.B -/+inroot
|
|
Runs
|
|

in your root window. Like the

.I inwindow
|
|
option it no longer locks the screen, it just looks good.
|
|
.TP 5
|
|
.B -/+remote
|
|
The
|
|
.I remote
|
|
option tells
|
|
.B xlock
|
|
to not stop you from locking remote X11 servers. This option should be
|
|
used with care and is intended mainly to lock X11 terminals which cannot
|
|
run
|
|
.B xlock
|
|
locally. If you lock someone else's workstation, they will have to know
|
|
.B your
|
|
password to unlock it. Using
|
|
.I +remote
|
|
overrides any resource derived values for
|
|
.I remote
|
|
and prevents
|
|
.B xlock
|
|
from being used to lock other X11 servers. (Use `+' instead of `-' to
|
|
override resources for other options that can take the `+' modifier
|
|
similarly.)
|
|
.TP 5
|
|
.B -/+mono
|
|
The
|
|
.I mono
|

option causes
|
|
.B xlock
|
|
to display monochrome, (black and white) pixels rather than the default
|
|
colored ones on color displays.
|
|
.TP 5
|
|
.B -/+allowaccess
|
|
This option is required for servers which do not allow clients to modify
|
|
the host access control list. It is also useful if you need to run x
|
|
clients on a server which is locked for some reason... When
|
|
.I allowaccess
|
|
is true, the X11 server is left open for clients to attach and thus
|
|
lowers the inherent security of this lock screen. A side effect of using
|
|
this option is that if
|
|
.B xlock
|
|
is killed -KILL, the access control list is not lost.
|

.TP 5

.TP 10
|
|
.I off

|
means no VT switch locking.

|

means VT switch locking + switching to xlock VT when activated.
|
|
.TP 10

means VT switch locking + switching to xlock VT when activated +
|
|
switching back to previous VT when desactivated.
|

.TP 10
|

.I noswitch

means VT switch locking only when xlock VT is active.

The

who started

.SH **WARNING**
|
|
.B xlock
|
|
can appear to hang if it is competing with a high-priority process for
|
|
the CPU. For example, if
|
|
.B xlock
|
|
is started after a process with 'nice -20'
|
|
(high priority),
|
|
.B xlock
|
|
will take considerable amount of time to respond.

|
|
.SH "SHADOW PASSWORDS"
|
|
If the machine is using a shadow password system, then
|
|
.B xlock
|
|
may not be set up to get the real password and so must be given one
|
|
of its own. This can be either on the command line, via the
|
|
.B -cpasswd
|
|
option,
|
|
or in the file
|
|
.BR $HOME/.xlockrc ,
|
|
with the first taking precedence. In both cases an encrypted password
|
|
is expected (see makekey(8)). If neither is given, then
|
|
.B xlock
|
|
will prompt for a password and will use that, also storing an
|
|
encrypted version of it in
|
|
.B $HOME/.xlockrc
|
|
for future use.

|
|
.SH "XLOCK AND SSH-AGENT"
|
|
If you use ssh-agent(1) to avoid entering a passphrase every time you use
|
|
one of your ssh(1) private keys, it's good security practice to have
|
|
ssh-agent forget the keys before you leave your terminal unattended. That
|
|
way, an attacker who takes over your terminal won't be able to use your
|
|
private ssh keys to log in to other systems. Once you return to your
|
|
terminal, you can enter the passphrase and re-add the keys to ssh-agent.
|
|
There are a couple of ways in which
|
|
.B xlock
|
|
can help to automate this process. Firstly, the
|
|
.I startCmd
|
|
option allows
|
|
.B xlock
|
|
to be configured to run 'ssh-add -D' every time you lock the screen, so
|
|
that your keys are automatically deleted from ssh-agent. If the
|
|
passphrase on your ssh keys is the same as your password, then
|
|
.B xlock
|
|
can also be made to re-add the keys to ssh-agent when you unlock the
|
|
screen, via the
|
|
.I pipepassCmd
|
|
option. This requires a bit of scripting, as the command must read your
|
|
password from standard input and then automate the interaction with
|
|
ssh-add to re-add the keys. There is an example of such a script in the
|
|
.B xlock
|
|
distribution - see
|
|
.I etc/xlockssh*
|
|
.sp
|
|
.SH BUGS
|
|
"kill -KILL
|
|
.B xlock
|
|
" causes the server that was locked to be unusable, since all hosts
|
|
(including localhost) were removed from the access control list
|
|
to lock out new X clients, and since
|
|
.B xlock
|
|
could not catch SIGKILL, it terminated before restoring the access
|
|
control list. This will leave the X server in a state where
|
|
\fI"you can no longer connect to that server,
|
|
and this operation cannot be reversed unless you reset the server."\fP
|
|
-From the X11R4 Xlib Documentation, Chapter 7.
|
|
.br
|
|
NCD terminals do not allow xlock to remove all the hosts from the access
|
|
control list. Therefore you will need to use the "-remote" and
|
|
"-allowaccess" switches. If you happen to run without "-allowaccess" on an
|
|
NCD terminal,
|
|
.B xlock
|
|
will not work and you will need to reboot the terminal, or simply go into
|
|
the SETUP menus, under 'Network Parameters', and turn off TCP/IP access
|
|
control.
