Best viewed with vim5, using ts=4
This code was mainly put together by looking at the
following programs:
asclock
A neat piece of equip, used to display the date
and time on the screen.
Comes with every AfterStep installation.
Source used:
How do I create a not so solid window?
How do I open a window?
How do I use pixmaps?
pppstats
A program that prints the amount of data that
is transferred over a ppp-line.
Source used:
How do I read the ppp device?
------------------------------------------------------------
Author: Martijn Pieterse (pieterse@xs4all.nl)
This program was hacked together between the 7th of March
and the 14th of March 1998.
This program might be Y2K resistant. We shall see. :)
This program is distributed under the GPL license.
(as were asclock and pppstats)
Known Features: (or in non M$ talk, BUGS)
* only ppp0 will be read
use wmifs if you want to read more than one ppp connection
not sure about this.
* the leds won't be reliable with
more than 1 ppp connection
* there is an iconwin, and win variable.
I have no clue why only win shouldn't
be enough. Will check it out later.
* The afterstep what seems the shift the
pixmap a bit. Don't know how and why.
It works in the WindowManager.
Things to do:
Split up main()

Thanks

Most of the ideas, and jumpstarting it:
#linuxnl, without this irc-channel wmppp would've never seen the light!
CCC (Constructive Code Criticism):
Marcelo E. Magallon
Thanks a LOT! It takes a while to get me convinced... :)
Minor bugs and ideas:
Marc De Scheemaecker / David Mihm / Chris Soghoian /
Alessandro Usseglio Viretta
and ofcourse numerous ppl who send us bug reports.
(numerous? hmm.. todo: rephrase this :) )
----
Changes:
---
02/29/2004 (Tom Marshall, tommy@home.tig-grr.com)
* Patch to add a special interface name "auto" for the -i
option. "wmifs -i auto" will automatically select the
first up interface.
01/08/2004 (Peter Samuelson, peter@samba-tng.org)
* Patch to make make sampling and scrolling intervals
customizable, adds new options -I and -s.
01/15/2002 (Matyas Koszik, koszik@debijan.lonyay.edu.hu)
* Patch that fixes segfaults on long interface names.
08/31/2001 (Davi Leal, davileal@terra.es)
* Patch that cuts long interface names, so they look
good in wmifs. For example, "dummy0" gets displayed
as "dumm0", "vmnet10" as "vmn10", etc.
06/16/2001 (Jorge García, Jorge.Garcia@uv.es)
* Added the LockMode, so wmifs doesn't swap to another
interface if the one requested with "-i" isn't up.
05/06/2001 (Jordi Mallach, jordi@sindominio.net)
* Integrated many patches, fixing issues with suspended
wmifs.
07/21/1999 (Stephen Pitts, smpitts@midsouth.rr.com)
* Added new constant: BUFFER_SIZE to determine the size
of the buffer used in fgets() operations. Right now,
its at 512 bytes. Fixed crashing on my system when
one line of /proc/net/dev was longer than 128 bytes
04/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Changed the "middle of the waveform" line color
* Moved the RedrawWindow out of the main loop.
Lightens the system load
02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Torn wmppp and wmifs apart.
This is gonna be wmifs
* Added parse_rcfile
* Added waitpid, to get rid of the zombies, spotteb by Alessandro Usseglio Viretta
30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Used the DrawStats routine from wmifs in wmppp
* I decided to add a list in this source file
with name of ppl who helped me build this code better.
* I finally removed the /proc/net/route dependency
All of the connections are taken from /proc/net/dev.
/proc/net/route is still used for checking if it is on-line.
27/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* WMIFS: stats scrolled, while red led burning
* WMPPP: changed positions of line speed
25/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Changed the checknetdevs routine, a lot!
23/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added line speed detection. via separate exec. (this has to be suid root!)
Speed has to be no more than 99999
* Added speed and forcespeed in ~/.wmppprc and /etc/wmppprc
* wmifs: added on-line detection scheme, update the bitmap coordinates
* wmppp: the x-button now allways disconnects.
22/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added /etc/wmppprc support, including "forced" mode.
* Added /etc/wmifsrc support, including "forced" mode.
21/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Moved the stats one pixel down.
* Added status led in wmifs.
* Changed RX/TX leds of wmifs to resemble wmppp
* Added the "dot" between eth.0 ppp.0 etc.
* Changed to wmifs stats to match wmppp stats (only pppX changed)
* Made sure that when specified -t 1, it stayed that way, even
when longer than 100 minutes online
* With -t 1, jump from 59:59 to 01:00 instead of 99:59 to 01:40
16/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added "all" devices in wmifs
* Added "lo" support only if aked via -i
* Added on-line time detection (using /var/run/ppp0.pid)
* Added time-out for the orange led. (one minute)
15/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Another wmppp-master.xpm.
Line speed detection being the main problem here.. :(
* Moved START_COMMAND / STOP_COMMAND to ~/.wmppprc
Return 0, everything went ok.
Return 10, the command did not work.
Please note, these functions are ran in the background.
* Removed the ability to configure
* When "v" is clicked, an orange led will appear.
if the connect script fails (return value == 10)
it will become dark again. Else the on-line detection will
pick it up, and "green" it.
14/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added "-timer"
* Added "-display" support
* Changed pixmap to a no-name pixmap.
+ Changed LED positions
+ Changed Timer position
+ Changed Stats Size
05/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added ~/.wmifsrc support.
* Put some code in DrawStats
* Check devices when pressing "device change"
03/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added code for wmifs
28/03/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* forgot what i did.. :)
27/03/1998 (Martijn Pieterse, pieterse@xs4all.nl)
* Added on-line detection
Scan through /proc/net/route and check everye line
for "ppp".
* A bit of code clean-up.
