While <B>xlock</B> 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 <B>xlock</B>. 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").

In pipes it is the maximum length of a system. In flow and swarm it is the length of the lines. In atlantis it is the shark size. A negative number allows for randomness, simi- lar to <I>count.</I> 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 picture covers the full screen. Set to 0 for full screen on fast machines. <B>-ncolors</B> <I>num</I> The <I>ncolors</I> option sets the maximum number of colors to be used. <B>-saturation</B> <I>value</I> The <I>saturation</I> option sets saturation of the color ramp used to <I>value</I> <I>.</I> 0 is grayscale and 1 is very rich color. 0.4 is a nice pastel. <B>-erasemode</B> <I>modename</I> As of this writing there are over 12 erase modes supported (if its not chosen its assumed random). The erase modes are random_lines, random_squares, venetian, triple_wipe, quad_wipe, circle_wipe, <B>-/+inwindow</B> Runs <B>xlock</B> 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</B> no longer locks your screen, it just looks good. <B>-/+inroot</B> Runs <B>xlock</B> in your root window. Like the <I>inwindow</I> option it no longer locks the screen, it just looks good. <B>-/+remote</B> The <I>remote</I> option tells <B>xlock</B> 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</B> locally. If you lock someone else's workstation, they will have to know <B>your</B> password to unlock it. Using <I>+remote</I> overrides any resource derived values for <I>remote</I> and prevents <B>xlock</B> from being used to lock other X11 servers. (Use `+' instead of `-' to override resources for other options that can take the `+' modifier simi- larly.) <B>-/+mono</B> The <I>mono</I> option causes <B>xlock</B> to display monochrome, (black and white) pixels rather than the default colored ones on color dis- plays. <B>-/+allowaccess</B> 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 rea- son... When <I>allowaccess</I> 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</B> is killed -KILL, the access control list is not lost. <B>-vtlock</B> <I>modename</I> This option is used on a XFree86 system to manage VT switching in [off|noswitch|switch|restore] mode. <I>off</I> means no VT switch locking. <I>switch</I> means VT switch locking + switching to xlock VT when acti- vated. <I>restore</I> means VT switch locking + switching to xlock VT when acti- vated + switching back to previous VT when desactivated. <I>noswitch</I> means VT switch locking only when xlock VT is active. <B>-/+allowroot</B> The <I>allowroot</I> option allows the root password to unlock the server as well as the user who started <B>xlock</B>. May not be able to turn <B>-echokey</B> <I>echokey</I> The text character to use for echo key in <I>echokeys</I> <I>.</I> <B>-/+enablesaver</B> By default <B>xlock</B> will disable the normal X server's screen saver since it is in effect a replacement for it. Since it is possible to set delay parameters long enough to cause phosphor burn on some displays, this option will turn back on the default screen saver which is very careful to keep most of the screen black. <B>-/+resetsaver</B> By default <B>xlock</B> will call XResetScreenSaver. This may be unde- sirable with DPMS monitors. <B>-/+grabmouse</B> The <I>grabmouse</I> option causes <B>xlock</B> to grab the mouse and keyboard, this is the default. <B>xlock</B> can not lock the screen without this. <B>-/+grabserver</B> The <I>grabserver</I> option causes <B>xlock</B> to grab the server. This is not usually needed but some unsecure X servers can be defeated without this. <B>-/+install</B> Allows <B>xlock</B> to install its own colormap if <B>xlock</B> runs out of col- ors. May not work on with some window managers (fvwm) and does not work with the -inroot option. <B>-/+mousemotion</B> Allows you to turn on and off the sensitivity to the mouse to bring up the password window. <B>-/+sound</B> Allows you to turn on and off sound if installed with the capabil- ity. <B>-/+timeelapsed</B> Allows you to find out how long a machine is locked so you can complain to an administrator that someone is hogging a machine. <B>-/+usefirst</B> The <I>usefirst</I> option causes <B>xlock</B> to use the keystroke which got you to the password screen as the first character in the password. The default is to ignore the first key pressed. <B>-/+verbose</B> Verbose mode, tells what options it is going to use. <B>-nice</B> <I>nicelevel</I> The <I>nice</I> option sets system nicelevel of the <B>xlock</B> process to <I>nicelevel</I> <I>.</I> option sets the font to be used for the text that is displayed in the lower part of the password screen. <B>-fg</B> <I>color</I> The <I>fg</I> option sets the color of the text on the password screen to <I>color</I> <I>.</I> <B>-bg</B> <I>color</I> The <I>bg</I> option sets the color of the background on the password screen to <I>color</I> <I>.</I> <B>-foreground</B> <I>color</I> The <I>foreground</I> option sets the color of the text on the password screen to <I>color</I> <I>.</I> <B>-background</B> <I>color</I> The <I>background</I> option sets the color of the background on the password screen to <I>color</I> <I>.</I> <B>-username</B> <I>string</I> Text <I>string</I> is shown in front of user name, defaults to "Name: ". <B>-password</B> <I>string</I> Text <I>string</I> is the password prompt string, defaults to "Password: ". <B>-info</B> <I>string</I> Text <I>string</I> is an informational message to tell the user what to do, defaults to "Enter password to unlock; select icon to lock.". <B>-validate</B> <I>string</I> Text <I>string</I> is a message shown while validating the password, defaults to "Validating login..." <B>-invalid</B> <I>string</I> Text <I>string</I> is a message shown when password is invalid, defaults to "Invalid login." <B>-geometry</B> <I>geom</I> The <I>geometry</I> option sets <I>geom</I> the size and offset of the lock win- dow (normally the entire screen). The entire screen format is still used for entering the password. The purpose is to see the screen even though it is locked. This should be used with caution since many of the modes will fail if the windows are far from square or are too small (size must be greater than 0x0). This should also be used with -enablesaver to protect screen from phos- phor burn. <B>-icongeometry</B> <I>geom</I> The <I>icongeometry</I> option sets <I>geom</I> the size of the iconic screen (normally 64x64) seen when entering the password. This should be used with caution since many of the modes will fail if the windows <B>-/+showfps</B> Turn on/off frame per sec display, available on atlantis, atun- nels, bubble3d, cage, fire, gears, invert, lament, moebius, morph3d, rubik, sballs, stairs, and superquadrics. <B>-/+fpstop</B> Turn on/off frame per sec display on top of screen, used if showfps is on. <B>-fpsfont</B> <I>fontname</I> The <I>fpsfont</I> option sets the font to be used in the frame per sec display, used if showfps is on. <B>-/+use3d</B> Turn on/off 3d view, available on bouboule, pyro, star, and worm. <B>-delta3d</B> <I>value</I> Space between the center of your 2 eyes for 3d mode. <B>-none3d</B> <I>color</I> Color used for empty size in 3d mode. <B>-right3d</B> <I>color</I> Color used for right eye in 3d mode. <B>-left3d</B> <I>color</I> Color used for left eye in 3d mode. <B>-both3d</B> <I>color</I> Color used for overlapping images for left and right eye in 3d mode. <B>-program</B> <I>programname</I> The <I>program</I> option sets the program to be used as the fortune gen- erator. Currently used only for marquee and nose modes. <B>-messagesfile</B> <I>formatted-filename</I> The <I>messagesfile</I> option sets the file to be used as the fortune generator. The first entry is the number of fortunes, the next line contains the first fortune. Fortunes begin with a "%%" on a line by itself. Currently used only for marquee and nose modes. If one exists, it takes precedence over the fortune program. <B>-messagefile</B> <I>filename</I> The <I>messagefile</I> option sets the file whose contents are displayed. Currently used only for marquee and nose modes.

For example, if <B>xlock</B> is started after a process with 'nice -20' (high priority), <B>xlock</B> will take considerable amount of time to respond. </PRE> <H2>SHADOW PASSWORDS</H2><PRE> If the machine is using a shadow password system, then <B>xlock</B> 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</B> option, or in the file <B>$HOME/.xlockrc</B>, with the first taking precedence. In both cases an encrypted password is expected (see <B>makekey(8)</B>). If neither is given, then <B>xlock</B> will prompt for a password and will use that, also storing an encrypted version of it in <B>$HOME/.xlockrc</B> for future use. </PRE> <H2>XLOCK AND SSH-AGENT</H2><PRE> If you use <B>ssh-agent(1)</B> to avoid entering a passphrase every time you use one of your <B>ssh(1)</B> private keys, it's good security practice to have ssh-agent forget the keys before you leave your terminal unat- tended. 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</B> can help to automate this process. Firstly, the <I>startCmd</I> option allows <B>xlock</B> 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 <I>that</I> <I>server,</I> <I>and</I> <I>this</I> <I>operation</I> <I>cannot</I> <I>be</I> <I>reversed</I> <I>unless</I> <I>you</I> <I>reset</I> <I>the</I> <I>server."</I> -From the X11R4 Xlib Documentation, Chapter 7. 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</B> will not work and you will need to reboot the terminal, or simply go into the SETUP menus, under 'Network Parame- ters', and turn off TCP/IP access control. </PRE> <H2>SEE ALSO</H2><PRE> <B>X(1)</B>, Xlib Documentation. </PRE> <H2>AUTHOR</H2><PRE> Maintained by: David Albert Bagley, <<I>bagleyd@tux.org</I>> The latest version is currently at: <I>ftp://ftp.tux.org/pub/tux/bagleyd/xlockmore</I> <I>ftp://ftp.x.org/contrib/applications</I> Original Author: Patrick J.
