If you rebuild the program, remember that it is done locally and does not affect the program generally available in /usr/bin. To rebuild the program you need the development set and access to the root password, to rebuild the manual page you need the document preparation set. The lock itself should be completely installed and ready to use. If you don't care about the source code, you should remove this entire directory. BUGS: The lock is currently only supported on UNIX version 3 on the UNIX PC, it will not run on UNIX version 4 without change. It has been tested on 3.0, 3.47 and 3.5. 09/04/86 - Svante C.

The program may be invoked either from a regular shell, or from the user agent. .P The password used is the same one as the login password for the user invoking it, unless the .B -p option is used when .I elock is invoked from a regular shell. .SS Options .sp .TP -p This option, when specified, will prompt for another password than the users. It will prompt twice, to confirm the correct entry of the password. The password is only in effect for one invokation of .B elock. The password will not be shown on the display. .sp If the verification of the password fails, then .I elock exits immediately with a non-zero status code. .SH EXAMPLES .nf elock -p Enter password: Verify password: .fi .SH FILES .nf /etc/passwd - where the default password is read /usr/bin/elock - the actual program /usr/lib/ua/Office - updated to contain elock entry /usr/lib/ua/elock.hlp - the on-line help file /usr/lib/wfont/elock.X - font file for caption display /usr/man/local/man1/elock.1 - this document .fi .SH BUGS If .B elock is killed from another terminal by the superuser, and it was running on the bit-mapped display, there is a risk that the phone manager, the status manager and the window manager may be permanently disabled. .P Due to a problem with the phone manager, there is a risk that there might be left-over call-screens still active when .B elock is exited and any of the phonemanager keys have been pressed. This can only happen under very special circumstances, and does not constitute a security risk. If it does happen, select the call-screen from the window manager, and exit (you may have to exit several times due to buffering by the phone manager). .P If .B elock is run when su'd through root to a login name that has .I NONE or some such, non passwd(1) generated, field as the password in /etc/passwd, then there is no way of unlocking but to dial in from another machine as root and kill the process. .P The implementation when run from a remote terminal is very simplistic, but safe. .P Due to the nature of the special concerns caused by the kernel support for system windows on the UNIX PC, this program is not very portable. 0707070000020014571006440001460001440000010532160373060067300001200000000663remove.sh# Remove elock - Unixpc locking program by /SCS # NOTE the source is NOT deleted!! echo "The source code in .../SRC/ELOCK will NOT be removed!" rm -f /usr/bin/elock rm -f /usr/lib/wfont/elock.X rm -f /usr/lib/ua/elock.hlp rm -f /usr/man/local/man1/elock.1 [ -z "`ls /usr/man/local/man1`" ] && rmdir /usr/man/local/man1 [ -z "`ls /usr/man/local`" ] && rmdir /usr/man/local [ -z "`ls /usr/man`" ] && rmdir /usr/man uaupd -r Elock Office 0707070000020065111006440001460001440000010366660372736237000001300000003517install.sh# Install elock - Unixpc locking program by /SCS echo "$HOME/Filecabinet/SRC/ELOCK/README contains information." if [ ! -d /usr/man ] #is there no elegant way of doing this?? then mkdir /usr/man chown bin /usr/man; chgrp bin /usr/man chmod 755 /usr/man fi if [ ! -d /usr/man/local ] #and this?? then mkdir /usr/man/local chown bin /usr/man/local; chgrp bin /usr/man/local chmod 755 /usr/man/local fi if [ ! -d /usr/man/local/man1 ] #and this?? then mkdir /usr/man/local/man1 chown bin /usr/man/local/man1; chgrp bin /usr/man/local/man1 chmod 755 /usr/man/local/man1 fi if [ ! -d $HOME/Filecabinet/SRC ] then mkdir $HOME/Filecabinet/SRC chown $LOGNAME $HOME/Filecabinet/SRC chmod 755 $HOME/Filecabinet/SRC fi if [ ! -d $HOME/Filecabinet/SRC/ELOCK ] then mkdir $HOME/Filecabinet/SRC/ELOCK chown $LOGNAME $HOME/Filecabinet/SRC/ELOCK chmod 755 $HOME/Filecabinet/SRC/ELOCK fi HERE=`pwd` cd $HOME/Filecabinet/SRC/ELOCK cpio <$HERE/files.cpio -icBdm chown $LOGNAME *; chgrp users * mv elock /usr/bin/elock cp elock.1 /usr/man/local/man1/elock.1 cp elock.hlp /usr/lib/ua/elock.hlp chown bin /usr/man/local/man1/elock.1 /usr/lib/ua/elock.hlp /usr/bin/elock chgrp bin /usr/man/local/man1/elock.1 /usr/lib/ua/elock.hlp chmod 444 /usr/man/local/man1/elock.1 /usr/lib/ua/elock.hlp chgrp sys /usr/bin/elock; chmod 2105 /usr/bin/elock # non fatal if no font file is available if [ ! -f /usr/lib/wfont/oldenglish.18 ] then if [ -f oldenglish.18 ] then cp oldenglish.18 /usr/lib/wfont/elock.X chown bin /usr/lib/wfont/elock.X chgrp bin /usr/lib/wfont/elock.X chmod 444 /usr/lib/wfont/elock.X fi else ln /usr/lib/wfont/oldenglish.18 /usr/lib/wfont/elock.X chmod o+r /usr/lib/wfont/elock.X fi cat <O.$$ Name=Elock Default = Open Open=EXEC -d /usr/bin/elock Help=EXEC -d /usr/bin/uahelp -h /usr/lib/ua/elock.hlp END uaupd -r Elock -a O.$$ Office rm -f O.$$ 0707070000020014611006440001460001440000010542260372736364700001200000010055elock.man eeeelllloooocccckkkk((((1111)))) UUUUNNNNIIIIXXXX 5555....0000 ((((UUUUNNNNIIIIXXXX PPPPCCCC)))) eeeelllloooocccckkkk((((1111)))) NNNNAAAAMMMMEEEE elock - locks the terminal from use without logging out SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS elock [-p] DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN This program clears the screen, displays a caption to the effect that the terminal is locked, and then waits for someone to enter the correct password.

This will ensure that nobody gains unauthorized access to your machine when \ you temporarily leave it during the working day, thereby increasing the \ security of your system. When the \UL\Electronic Lock\US\ is in place, it will cover the entire \ screen with an essentially empty window. The only information visible \ is a caption to the effect that the machine is in the locked state. The \ key to the lock is the same password that is used for login, or \ a different password of your choice if you lock the machine from \ the UNIX shell. The only effect of the \UL\Electronic Lock\US\ is to disable all forms \ of input from the keyboard or mouse at the terminal where it was invoked. \ All other processes in the machine will run uninterrupted.\EOT\ Name = Locking the lock Llabel = "LOCKING UNIX PC" Slabel = "LOCKING" Branch = Using the lock, Locking the lock, Opening the lock Title = "How to lock the electronic lock" Text = \CEN\\BL\Locking the UNIX PC lock\BS\ There are two ways to lock the \UL\Electronic Lock\US\. You may either \ invoke the lock from the \UL\User Agent\US\, or you may give the \ \BL\elock\BS\ command from the shell. In either case, the default \ key password that will unlock the machine is the password of the \ \UL\effective\US\ user running the program. This means that the \ password will be that of the user last \UL\su\US\:ed to, not the password \ of the user originally logged in. Normally this aspect is only of \ concern to super users. If no password is defined for the active user, \ you will be prompted to enter one before the machine is locked. Once locked, the machine will be unusable from that terminal until \ the correct key password is entered. \UL\root\US\ may of course kill the process from another terminal, \ but this practice is strongly discouraged since it may cause the \ \UL\Phone Manager\US\, the \UL\Window Manager\US\ and the \UL\Status \ Manager\US\ to be permanently disabled. This does not lessen the \ security offered, since anyone with access to the \UL\root\US\ user \ must be assumed to be an authorized user. The \UL\Electronic Lock\US\ may also of course be bypassed by physically \ resetting the machine, and loading a stand alone UNIX from a floppy disk. \ This kind of intrusion is likely to take time, and is very difficult to \ do undetected so this is not a really strong concern. The goal of the \ \UL\Electronic Lock\US\ is to provide the same amount of security as \ logging out would, without the inconvenience.\EOT\ Name = Opening the lock Llabel = "OPENING UNIX PC" Slabel = "OPENING" Branch = Using the lock, Locking the lock, Opening the lock Title = "How to unlock the electronic lock" Text = \CEN\\BL\Opening the UNIX PC lock\BS\ To open the \UL\Electronic Lock\US\, first press any key when the machine \ is in the locked state. The lock will then prompt for a key password, \ which must be entered followed by a . The entered key is compared to the one specified when the machine \ was locked, or to the login password if no key was given then. If the \ two keys match, the machine will revert to the unlocked, normal state. If \ they mismatch the lock will not open, and the machine will still be locked \ from use. \EOT\ 0707070000020014331006440001460001440000010475270372733604000001600000033736oldenglish.18�33#+��+�+�f+�� +��+�@ +��+��+�x+�+��+�d+�+��+� P+� �+� �+�(+�,�'+�+�$+�( �(+�,�(+�,�(+�,�(+�,�,+�0�+��+�$*+�.�!+�%�2+�7�*+�.'+�+&+�*'+�+�(+�,�&+�*�#+�'�)+�-�*+�.�3+�8 �%+�)"&)+�-# $+�($+�$�+�%�+�&,+�&�+�'t+�(+�(�+�)` +�* +�*R+�*� +�+D%+�)+�+�,�+�-0+�-�+�.x+�/+�/� +�0d+�0�+�1V"+�&1�+�2�+�3�+�4<>��|~~~<<88888<<~~~|��<|x��x|<��8�� <?��~?�~?�~?�~?�~?�?�?�?�?��`0��?��8�À��~�~�~��~��~�~�~�~��?��~<��~?��?�p�p�8��2��?�?��?�p��#0|��~�~�~�|��?��>��0@��?��?��~<��?��>�>�>�>�>�~��x0x��?��|��?��~�||<x8xxx�x�x�|��?��||��|8��?��<��g��g��g��78�1��0@�8?��?��`�v��|~��?��?�g��c��c?��c?��c��c��c��c��c��c?��c��c��!��1��1��1��1?��1?��1?��3?��??��?��?��?��?��@~<��?��`~�x?�>�x?��x?��8?��8?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��l?�<?��L��?�?��1��1��1?��1��1��1��0��?��?��?��>��?�3��?�1��1?��0��0��0��0��0��?��0��0��0��0��1��3��?��?�00000��x�>��>��?��?��??��?��?��?��?v��|8 | ?��0��?��?��'��#��#��#��#��c��c��s��#��#��!��!��!��!��#��3��?��?��?��#��!?�< �0��>�?��0��|8��?��~��??��?� ~� ��1��??��3��3��1��1��1��1�p1�01��1��3��|3��3��3��3��3��3��??��?��?��7��#��#�x!�! �`��g�c��?��??��@o��o��?��?��?��?��?��?��v~~<�`�<��>��<��?�� ?��?��|�<?��?��?��?��g��?�?��>|��'��#��#��#��#?��#?��#?��?��?��?��?��c��#��#�#�#�#�#�#�#�#��#��3��?��?�0?00 ��?�x��>��?��?��?��?��?�?��?��x�>>??��?��?�g��c��c��#?��#?��#?��#?�`�#��#��#��#��<3��3��3��3��3��3��3��3��3?��??��?��?��0?>0000��?��?��<��<�?��?�?��?��?��x|��x��?��?��?��?��?��?��?�?�?��?��?��?�?�?��?�?��?�?�?�?�?�?�?��|8�x��?��y��?��q��?|>��?��?�?��A��c��c��3��?��9�ys>0��x��8��@�� ?��O?��o?��?��?��?��?��?��|�??><p�8��`?�~?��?��><��?��?��?�c�#��3��?��??�?��`?�`�@��?�@��?��?��??>��<�>?�~��?�?�8?��?��?��?��?��?��?��?��?��x0��?��x`��@��?��?��À��~�~�~�~�~��?��?�>��?��x��?px��c�c��#�?��8��?��?��?��?��?��?��?��?��?��?��~~~|>�?0��?��?��?|0��|0x��0��:`��?��pp��` p��?��?��?��?��?��?��?��?��?��p�x��?��?��?��x��~��?��?��`?��~�~�~�~�~�~��x��8`�� ?��?��?��?��?��?��?��?��?��?��?x�8�<��0@�|��?��?��0?��0?��?��?�~�|��?��?��`��?��`�x?��?8p��?��?�?�?�?�?�?��?��?��?��?��?||�||��8��?��p0707070000020060451021050000020000030000010120400372734171600000600000133243elockR]��#�l�� .textl�` .data �@.bss � ��.lib \ \/< \N�1X� OQ�.�/HJ�f��/H#�0N�R��,`��.��N�1B.��N�1Bp`L�N^NuNV��H�B��B�/< �N�1XO-@��lp�`�p.�Hn��/.��N�1,POr��f�p��o�Jn��f`��Hn��Hn��N�1tPOJ�g`��p0.�� fpB��p��ob .��Ѐ"n01�n��fD .��"�Ё"nB1p.�Hn�� .��"�Ё"nA�HPN�1POR��`R��`��`�..��N�1Bp`L�N^NuNqNV��H�N�1�-@��N�PJ�f.� �/.��N��XO.� �/.��N��XO.��Hn��Hn��/< �N�O�.� �/.��N��XO.��/.��/.��N�1HPO.� �/.��N�1�XOB�HxT/.��N�1�PO.� �/.��N�1~XO.��N�1@��fN��.��g��.� �/.��N�XO.� �/.��N�1~XON��J�f.� /.��N��XO.� /.��N��XO.��Hn��Hn��/< N�4O�B�/.��/.��N�1HPOL�N^NuNV��H�N�1�#� �N�1�#� �f8B�p/N�1nXON�1�B�/< +/< $/< N�1TO�`vp.�N�1�.� �p/N�1nXO.� �p/N�1nXOp.�N�1B�N�1�r��fp��0g��B�N�1.�p/N�1nXON�1�L�N^NuNV��H�N�1�"9 Ȳ�fp .�/9 �N�1�XOL�N^NuNV��H��Hn��HxW/.N�1�O�p0.��r.��.�N�1�"� "n"�.�N�1 $p0.��r.��.�N�1ڐ�"� "n"�L��N^NuNV��H�p.�/.N�1�XO.�/.N�1�XOL�N^NuNqNV��H�N�1DB�N�1Bp.�N�1Bp.�N�1Bp.�/< �N�1XOJ�lp�`�B�N�1NB�N�1NN�1$p.�B�N�1XO.��pP/p/B�B�N�1�O�-@��l.� �/<0�N�1�XOp�`4B�HxW /.��N�1�PO.��N�B.� �/.��N�1�XOp`L�N^NuNV��H�N�10J�fp�`:N�1�-@��.� DHxW/.��N�1�POJ�lB�0p�`p`L�N^NuNV��H�N�1�-@��N�10J�fp�`0.� DHxW/.��N�1�POJ�lB�0p�`p`L�N^NuNV��H�p.�/< �N�1XO-@��Hn��HxW/.��N�1�O�-@��.��N�1BJ��fp`p`L�N^NuNV��H�Hn��HxW/.N�1�O�N�t-@��Hn��HxW/.N�1�O�L�N^NuNV��H�J�gN��-@��`ZN�1�.�N�1� @-H��J�f.� �/<0�N�1�XO��`n n��-h��.��N�1 J�f N�\-@��.��N�1 J�f��`6.��N�1 R�.�N�1B-@��.��/.��N�1XO-@�� n��` L�N^NuNV��H�B�/< �N�bXO @-H��f��`�.��Hn��N�1XOB�/< �N�4XO @-H��f��`�.��Hn��N�1XOJ�g��`�B�N�1�.�N�1�-@��.��N�1 U�"n��A�-H��.��/.��N�1�XO-@��.��N��Hn��N��XO.��N�1 R�.�N�1B-@��.��/.��N�1XO-@�� n��` L�N^NuNV��H�.�/< N�\XO @-H��fp�`@.�/.��N�1�XO-@��.��N�n.�/.��N�1XOJ�fp`p`L�N^NuNV��H�.�p/N�1nXOJ�g.�N�1B�/< N�1XO-@��lp�.�N��Hn��HxT/.��N�1�O�A��C�� 0��n��Hn��HxT/.��N�1�O�.�N�1� @-H��f$.� /<0�N�1�XOp.�N�1�B��Hn��HxT/.��N�1�O�.��N�1BJ�g B�N�1 n��` L�N^NuNV��H�.�/.N�1nXOL�N^NuNV��H� nH�H�g nR�� `�� n� L�N^NuNV��H��B9 �� B9 �B9 �B9 �B9 �By �B��p@��o* .��Ѐ"| <41 .��Ѐ"| �3�R��`�� | �` L��N^NuNqNV��H��N�1�#� XN�1�J�f�.��p/N�1nXOB�p/N�1nXOp.�N�1�-@��l.��p/N�1nXOp.�HxWB�N�1�PO$N�1��g$p.�HxW /9 XN�1�PO.� XN�1�`��L��N^NuNV��H�L�N^NuNqNV��H�N�1$N�1�-@��fdN�1�p.�Hx�pc/B�B�N�1�O�-@��B�/.N��XO-@��f.� �N�1�`��p��fp.�N��`B�N�1�N�1�B�N�16L�N^Nupusage: elock {-p} elock��/dev4elock: Incompatible UNIX ver %s /dev/kmem/dev/memelock: process not in core. .[11m[=1CLocked...[2JLocked...Touch any key to enter password[2JEnter password[10m[=0C/usr/bin/uahelpuahelp-h/usr/lib/ua/elock.hlp/usr/lib/wfont/elock.X/dev/windowelock: Can't make a new window.
