21 This code was mainly put together by looking at the
22 following programs:
23
24 asclock
25 A neat piece of equip, used to display the date
26 and time on the screen.
27 Comes with every AfterStep installation.
28
29 Source used:
30 How do I create a not so solid window?
31 How do I open a window?
32 How do I use pixmaps?
33
34 pppstats
35 A program that prints the amount of data that
36 is transferred over a ppp-line.
37
38 Source used:
39 How do I read the ppp device?

44 This program was hacked together between the 7th of March
45 and the 14th of March 1998.
46
47 This program might be Y2K resistant. We shall see. :)
48
49 This program is distributed under the GPL license.
50 (as were asclock and pppstats)
51
52 Known Features: (or in non M$ talk, BUGS)
53 * only ppp0 will be read
54 use wmifs if you want to read more than one ppp connection
55 not sure about this.
56 * the leds won't be reliable with
57 more than 1 ppp connection
58 * there is an iconwin, and win variable.
59 I have no clue why only win shouldn't
60 be enough. Will check it out later.
61 * The afterstep what seems the shift the
62 pixmap a bit. Don't know how and why.
63 It works in the WindowManager.
64
65 Things to do:
66 Split up main()

69 Thanks

71
72 Most of the ideas, and jumpstarting it:
73
74 #linuxnl, without this irc-channel wmppp would've never seen the light!
75
76 CCC (Constructive Code Criticism):
77
78 Marcelo E. Magallon
79 Thanks a LOT! It takes a while to get me convinced... :)

85 Alessandro Usseglio Viretta

91 ----
92 Changes:
93 ---
94 02/29/2004 (Tom Marshall, tommy@home.tig-grr.com)
95 * Patch to add a special interface name "auto" for the -i
96 option. "wmifs -i auto" will automatically select the
97 first up interface.
98 01/08/2004 (Peter Samuelson, peter@samba-tng.org)
99 * Patch to make make sampling and scrolling intervals
100 customizable, adds new options -I and -s.
101 01/15/2002 (Matyas Koszik, koszik@debijan.lonyay.edu.hu)
102 * Patch that fixes segfaults on long interface names.
103 08/31/2001 (Davi Leal, davileal@terra.es)
104 * Patch that cuts long interface names, so they look
105 good in wmifs. For example, "dummy0" gets displayed
106 as "dumm0", "vmnet10" as "vmn10", etc.
107 06/16/2001 (Jorge García, Jorge.Garcia@uv.es)
108 * Added the LockMode, so wmifs doesn't swap to another
109 interface if the one requested with "-i" isn't up.
110 05/06/2001 (Jordi Mallach, jordi@sindominio.net)
111 * Integrated many patches, fixing issues with suspended
112 wmifs.
113 07/21/1999 (Stephen Pitts, smpitts@midsouth.rr.com)
114 * Added new constant: BUFFER_SIZE to determine the size
115 of the buffer used in fgets() operations. Right now,
116 its at 512 bytes. Fixed crashing on my system when
117 one line of /proc/net/dev was longer than 128 bytes
118 04/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
119 * Changed the "middle of the waveform" line color
120 * Moved the RedrawWindow out of the main loop.
121 Lightens the system load
122 02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
123 * Torn wmppp and wmifs apart.
124 This is gonna be wmifs
125 * Added parse_rcfile
126 * Added waitpid, to get rid of the zombies, spotteb by Alessandro Usseglio Viretta
127 30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
128 * Used the DrawStats routine from wmifs in wmppp
129 * I decided to add a list in this source file
130 with name of ppl who helped me build this code better.
131 * I finally removed the /proc/net/route dependency
132 All of the connections are taken from /proc/net/dev.
133 /proc/net/route is still used for checking if it is on-line.
134 27/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
135 * WMIFS: stats scrolled, while red led burning
136 * WMPPP: changed positions of line speed
137 25/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
138 * Changed the checknetdevs routine, a lot!
139 23/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
140 * Added line speed detection. via separate exec. (this has to be suid root!)
141 Speed has to be no more than 99999
142 * Added speed and forcespeed in ~/.wmppprc and /etc/wmppprc
143 * wmifs: added on-line detection scheme, update the bitmap coordinates
144 * wmppp: the x-button now allways disconnects.
145 22/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
146 * Added /etc/wmppprc support, including "forced" mode.
147 * Added /etc/wmifsrc support, including "forced" mode.
148 21/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
149 * Moved the stats one pixel down.
150 * Added status led in wmifs.
151 * Changed RX/TX leds of wmifs to resemble wmppp
152 * Added the "dot" between eth.0 ppp.0 etc.
153 * Changed to wmifs stats to match wmppp stats (only pppX changed)
154 * Made sure that when specified -t 1, it stayed that way, even
155 when longer than 100 minutes online
156 * With -t 1, jump from 59:59 to 01:00 instead of 99:59 to 01:40
157 16/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
158 * Added "all" devices in wmifs
159 * Added "lo" support only if aked via -i
160 * Added on-line time detection (using /var/run/ppp0.pid)
161 * Added time-out for the orange led. (one minute)
162 15/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
163 * Another wmppp-master.xpm.
164 Line speed detection being the main problem here.. :(
165 * Moved START_COMMAND / STOP_COMMAND to ~/.wmppprc
166 Return 0, everything went ok.
167 Return 10, the command did not work.
168 Please note, these functions are ran in the background.
169 * Removed the ability to configure
170 * When "v" is clicked, an orange led will appear.
171 if the connect script fails (return value == 10)
172 it will become dark again. Else the on-line detection will
173 pick it up, and "green" it.
174 14/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
175 * Added "-timer"
176 * Added "-display" support
177 * Changed pixmap to a no-name pixmap.
178 + Changed LED positions
179 + Changed Timer position
180 + Changed Stats Size
181 05/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
182 * Added ~/.wmifsrc support.
183 * Put some code in DrawStats
184 * Check devices when pressing "device change"
185 03/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
186 * Added code for wmifs
187 28/03/1998 (Martijn Pieterse, pieterse@xs4all.nl)
188 * forgot what i did.. :)
189 27/03/1998 (Martijn Pieterse, pieterse@xs4all.nl)
190 * Added on-line detection
191 Scan through /proc/net/route and check everye line
192 for "ppp".
193 * A bit of code clean-up.
