- [This is a patched version of MOTD that has been built under 3.0 - cdl]
-
- CHANGES FOR 3.0
-
- The MOTD application no longer updates the /usr/adm/wtmp and /usr/adm/lastlog
- files. This deficiency in Workspace has been corrected in 3.0. Thus, there
- is no longer a LogoutHook component. You'll want to:
-
- dremove loginwindow LogoutHook
-
- if you were previously using the '/usr/local/bin/LogoutHook' component. You
- should also do
-
- dwrite loginwindow LoginHook /LocalApps/MOTD.app/MOTD
-
- to change the LoginHook from 'LocalApps/MOTD' to '/LocalApps/MOTD.app/MOTD'.
-
- MOTD now handles '*.rtfd' files but it no longer assumes that if the first
- character of a file is {, then it is in RTF format. It now only looks at
- file name extensions (*.rtf & *.rtfd) to determine if a file contains RTF.
-
- MOTD no longer uses the files mail.snd and newmail.snd on the /LocalLibrary/Sounds directory (these *.snd files contained the"You have
- mail" and "You have new mail" voice alerts). Instead, it contains
- localizable sound files in the MOTD.app application bundle itself.
-
- The system defaults have been moved from the MOTD.h to the file
- Defaults.strings in the MOTD.app application bundle.
-
-
- DESCRIPTION
-
- The MOTD application (designed to run as a LoginHook under loginwindow or
- be launched) displays the contents of the file /etc/motd (or any file you
- choose) in a window when a user logs on. By default, the application
- checks the modification date of the file against the user's last login
- time (as recorded in /usr/adm/wtmp) and does nothing if the file hasn't
- changed.
-
- The MOTD window has three buttons, one to hold the window on the screen
- (it goes away automatically in 25 seconds--the hold button displays the
- count down), another to quit (and proceed with the login) and a third to
- cancel the login (only enabled if MOTD is run as a LoginHook). MOTD also
- implements a Mail Alert panel which appears if there is unread mail. The
- panel automatically goes away (in a couple of seconds) if there isn't a
- new /etc/motd message.
-
- To get an idea of what MOTD does (without installing it), as root do:
-
- #touch /etc/motd
- #MOTD
-
- When used as a LoginHook, the window appears over a blank screen just as
- the user logs in. MOTD supports RTF.
-
-
- INSTALLATION
-
- To install MOTD as a LoginHook, put it on /LocalApps, put LogoutHook on /usr/local/bin and as root do:
-
- dwrite loginwindow LoginHook /LocalApps/MOTD.app/MOTD
-
- alternatively, the file /etc/ttys can be modified to include the -LoginHook
- arguments to loginwindow.
-
- You may want to consider commenting out the following lines in
- /usr/adm/monthly that trim the wtmp and lastlog files or else users may
- see messages they've read over again and the loging information won't
- be correct:
-
- # Trim the lastlog
- # cp -p /usr/adm/lastlog /usr/adm/lastlog.old
- # cat /dev/null > /usr/adm/lastlog
-
- # Trim wtmp
- # cp -p /usr/adm/wtmp /usr/adm/wtmp.old
- # cat /dev/null > /usr/adm/wtmp
-
- You may want to come up with some less frequent scheme for triming the
- wtmp file. A program that can do this, trimwtmp.c, is included and can
- be added to the /usr/adm/monthly cleanup. See the trimwtmp.c file for
- details. Finally, restart the window server (login as EXIT or reboot)
- for this to take effect. Update /etc/motd as appropriate.
-
- If you don't want to make MOTD a requirement for users, then don't make
- it a LoginHook but instead have interested users add it to their dock
- and set it launch at startup using the 'Preferences...' panel of Workspace.
-
- DEFAULTS
-
- MOTD has the following defaults that can be changed (if used as a LoginHook,
- they have to be changed in root's defaults database):
-
- File -- The file to display, defaults to /etc/motd.
-
- Wait -- The amount of time to display File, defaults to 25 seconds.
-
- MailWait -- The amount of time to display mail alert, defaults to
- 2 seconds.
-
- Hold -- Whether or not (Yes or No) to come up held, No by default.
- If Yes then the Hold button won't appear.
-
- OnlyOnce -- Whether or not (Yes or No) to check file date, Yes by
- default. If No, displays file on every login.
-
- The defaults can be changed via root's defaults database or by editing their
- values in the Defaults.strings file in the MOTD.app application bundle.
-
- MOTD also uses the SystemAlert default of the System entry in the defaults
- database to control voice messages on the mail alerts. This value can be
- set (by root if MOTD is a LoginHook) via the 'Use Voice Alerts' checkbox in
- the Preferences application. You may need to force an entry for SystemAlert
- by cycling the 'Use Voice Alerts' checkbox (turning off and on the check
- mark) as root's defaults database may not contain an entry for SystemAlert
- even though the checkbox is selected.
-
-
- FILE FORMAT
-
- The File is assumed to be any plain text format acceptable to a ScrollView.
- MOTD also recognizes the 'rtf' and 'rtfd' file extensions as RTF (rich text
- format) files and displays them as such. If you use RTF files with MOTD,
- it is probably best to create separate files, motd and motd.rtf, and change
- the File default above to use the motd.rtf (or motd.rtfd) file (dwrite the
- new File default as root if MOTD is a LoginHook):
-
- dwrite MOTD File /etc/motd.rtf
-
- This prevents network logins being presented with the RTF structured text.
-
-
- DIAGNOSTICS
-
- MOTD is designed to run as a LoginHook for the loginwindow program and thus
- always tries to return success (0), even on error, so that the user can still
- log in if the program runs into trouble. The 'Cancel Login' button causes
- the program to exit with failure (1) and abort the login.
-
-
- BUGS
-
- MOTD determines that a file is in RTF format based on its extension and
- doesn't look at content.
-
- An affirmative database value for Hold and OnlyOnce can be 'Yes' , YES' or
- 'yes' but not 'true' . Anything not starting with Y/y is considered 'No'.
-
- The console device that MOTD enters into the wtmp file is hardcoded in
- MOTD_main.m since basename(ttyname(0)) didn't work in the context of a
- LoginHook.
-
- The timeout should probably be a function of the number of lines of text
- in the file being displayed.
