3 * The CenterIM FAQ (frequently asked questions)
4 * originally by Konstantin Klyagin
5 * currently maintained by the CenterIM community.
12 Q: What about implementing such a neat <blah-blah> feature in centerim?
14 A: Hey, centerim is GPL and opensource, so feel free to contribute.
15 Don't wait for the maintainers to implement it, just do it
16 yourself and send a patch.
20 Q: Can't build it under FreeBSD..
22 A: Use gmake instead of make
26 Q: (by Paonia Ezrine, paonia@home.welcomehome.org)
27 When I run centerim in a xterm or from the console it is fine but
28 when I run it in a gnome terminal windows the screen does not update
29 correctly. Specificly the right side of the screen does not get
30 cleared after I send a message or other similar events.
32 A: (by Jakub Travnik, j.travnik@sh.cvut.cz)
34 It happens only with the gnome-terminal. centerim works fine on
35 linux-console and eterm (enlightenment) so it is problem with
36 gnome-terminal. It does not support all xterm sequences.
37 /usr/share/terminfo/g/gnome file could correct that (gnome users
38 should have it), so that ncurses will not use such a extended
39 sequences for gnome-terminal.
41 Workaround: For me it worked setting TERM variable to gnome and then
42 running centerim without problems.
52 Q: How do I authorize someone's request with centerim?
54 A: You'll see as soon as someone requests it.
58 Q: I can't use Ctrl-O to view history and Ctrl-Y to delete a line under
61 A: Execute the following before starting centerim:
67 Q: I can't get out from a dialog or a menu. When I press ESC, nothing
70 A: Have you ever used mc (Midnight commander)? It requires users to
71 press ESC twice to close a dialog, menu, etc. It's not a problem, but
72 just a terminal specific issue.
76 Q: How do I enable logging the protocol info, etc?
78 A: Run centerim with --debug flag.
82 Q: CenterIM compiles way too slow on my box. What's wrong?
84 A: C++ compiler optimization being a rather slow thing is on by default.
85 To turn it off, do the following.
86 [konst@morgue]$ CXXFLAGS=-O0 ./configure && make
90 Q: From: jeff covey <jeff.covey@pobox.com>
92 if i understand the faq correctly, centerim makes esc into escesc
93 because some terminals don't map esc properly. could the use of esc or
94 escesc be made a configuration choice? for me, hitting escape twice is
95 reallyreally annoyingannoying, especially if i'm two menus in, and to
96 get out, i have to hit escape four times in a rowrowrowrow.
98 A: From: lanzz@lanzz.org
100 it's a limitation of the console. keys like f1..f12, the arrows, etc,
101 generate sequences of characters starting with esc. if the application
102 was to handle esc as cancel unconditionally, you'll have arrows
103 cancelling your dialogs. so the app must do one of these things to
106 1. require esc-esc instead of single esc, as that disambiguates it
107 from the function keys
109 2. have a certain timeout and accepting the esc as a cancel only if
110 there wasn't a function sequence after the esc during the timeout
112 3. switch keyboard to raw or medium-raw mode and do keycode mapping
115 as 2. is annoying and sluggish (at least to me) and 3. is too much
116 work for too little gain, i think the current situation with double
117 esc is the best choice. centerim was using timeout esc in the past (i
118 think it's the default way ncurses handles esc) and at least i'm happy
121 perhaps there could be a configurable choice between double-esc and
122 timeout, if that doesn't complicate the input routines too much.
126 Q: From: staale@lorentzen.org

129 > + [icq] disconnected, turboing
133 > I've tried different icq-servers, with no luck. Anyone with a
134 > clue to what this can be?
136 A: It means exactly "turboing". You're loggin in and out too fast, so
137 that the server turns on DoS attack protection. All you can do is
138 to try again in half an hour.
142 Q: WTF?! My centerim binary is more than 20Mb. SOS! HELP! Virus? Aliens?
144 A: There are three steps you need to take.
146 1. Look at other applications written in C++ compiled in your system.
147 2. Read the install(1) and strip(1) man-pages.
148 3. Type "strip -s centerim; ls -l centerim"
152 Q: I need a program for sending messages on IM networks from the command
153 line. Is it possible to write a program that would use the centerim
154 libraries, or maybe there is a special batch mode in the program?
156 A: Batch mode like you described is not possible to be implemented, because
157 due to frequent logons followed by disconnections the servers will turn
158 on their DoS attacks protection. So there is the only decent way which
159 consists in sending messages in batch mode through an already running
160 centerim instance. If you want to run it like a "daemon", use
161 screen(1). More details on the batch mode usage can be found in the
166 Q: ICQ new UINs registration doesn't work! It just sends a request and
167 then after 30 seconds reports a timeout.
169 A: It does work. Though, the ICQ server doesn't report the "password is
170 too simple" situaion. Try to enter another one, more complicated. Also,
171 as far as I know, "xxx123" is complicated enough to be accepted by
176 Q: What about storing passwords in some kind of an encrypted mode in the
179 A: It doesn't make much sense, because in many cases they're transferred
180 unencrypted. And also the program must first decrypt them before sending,
181 so the one who really wants to find out them anyway will make it quite
182 easily. But if you still think that such a crypting will help, please
183 consult homepage of the program which was made especially for ones
184 like you: http://konst.org.ua/kripp/
188 Q: When $HOME/.centerim/config gets created, you should set it mode 0600
189 so only the user can read it. It contains passwords in clear text
190 which other users on a system could read.
192 A: Your filesystem permissions knowledge is very sound, but please just try
193 to access the config file before making any affirmations. You'll see
194 that the .centerim directiory permissions do not allow others to read
195 your configuration data.
