strlcpy() is broken
by Florian Westphal 18 Jan '05

18 Jan '05

Hi, the strlcpy() included with ngircd is broken. It will always return values smaller than the specified buffer length. This is very bad because you can no longer tell if truncation occured by looking at the return value (hence, the truncation checks in ngircd won't work if the included strlcpy is used). Trivial patch is attached. Florian

[Patch] Write Daemon Pid to file
by Florian Westphal 17 Jan '05

17 Jan '05

Attached is a small patch to NGIRCd CVS that writes the daemons pid to a file (Default: /var/run/ngircd/ngircd.pid). The pidfile can be changed via the -P <pidfile> or --pidfile <pidfile> options. The getpid.sh script included with ngircd does not work on FreeBSD 5.3-Stable (ps needs -ax switches). Also, the sample configuration file says 'one port, separated with ";"' ( the given example uses the correct "," seperator). Thanks, Florian

Problem connecting ngircd to irc-2.10.3p5 due to passwd length limits
by Florian Westphal 17 Jan '05

17 Jan '05

Hello, I am currently configuring a connection between ngircd 0.8.1 and a machine running irc 2.10.3p5. This failed at first because ngircd restricts passwords to 8 characters in length. I took a quick glance at RFC 1459, but i couldnt find any specification of a maximum password length, so I bumped CLIENT_PASS_LEN to 17 in src/ngircd/defines.h . Is there a particular reason why it is restricted to 8? (Or why it was chosen in the first place?) Thanks, Florian

Memleak in New_Connection()
by Florian Westphal 17 Jan '05

17 Jan '05

Hi, there seems to be a memory leak in New_Connection() (src/ngircd/conn.c), line 1044: 1018 ptr = (POINTER *)realloc( My_Connections, sizeof( CONNECTION ) * new_size ); 1019 if( ! ptr ) 1020 { 1021 /* realloc() ist fehlgeschlagen. Nun malloc() probieren: */ 1022 ptr = (POINTER *)malloc( sizeof( CONNECTION ) * new_size ); 1023 if( ! ptr ) 1024 { 1025 /* Offenbar steht kein weiterer Sepeicher zur Verfuegung :-( */ 1026 Log( LOG_EMERG, "Can't allocate memory! [New_Connection]" ); 1027 Simple_Message( new_sock, "ERROR: Internal error" ); 1028 close( new_sock ); 1029 return; 1030 } 1031 1032 /* Struktur umkopieren ... */ 1033 memcpy( ptr, My_Connections, sizeof( CONNECTION ) * Pool_Size ); [..] Debug ommitted... 1038 } 1043 /* Adjust pointer to new block */ 1044 My_Connections = (CONNECTION *)ptr; "My_Connections" gets overwritten, without calling free(). For the sake of simplicity I'd rather remove the malloc() call altogether. The attached patch does just that. Florian

by Alexander Barton 25 Dez '04

Changes since version 0.8.0 are: - Autoconf: Updated config.guess and config.sub - Added some more debug code ... - Fixed wrong variable names in output of "ngircd --configtest". - Debian: Fxied the name of the "default file" in the init script for ngircd-full packages. And do the test if the binary is executable after reading this file. - Enhanced the "test suite": please have a look at src/testsuite/README! You can download ngIRCd 0.8.1 (~270 KB) from: - <http://download.berlios.de/ngircd/ngircd-0.8.1.tar.gz> - <ftp://ftp.berlios.de/pub/ngircd/ngircd-0.8.1.tar.gz> - <ftp://Arthur.Ath.CX/pub/Users/alex/ngircd/ngircd-0.8.1.tar.gz> And the patch from 0.8.0 to 0.8.1 (~10 KB) as well as GnuPG signatures can be found here: - <ftp://ftp.berlios.de/pub/ngircd/> - <ftp://Arthur.Ath.CX/pub/Users/alex/ngircd/> This release has been tagged as "rel-0-8-1" in the CVS. Have fun! Regards Alex PS.: Merry Christmas! -- Alexander Barton, Freiburg, Germany http://www.barton.de/, alex(a)barton.de

Printing the number of connected users to a file
by Jens Kleine 25 Nov '04

25 Nov '04

Hi, I like to have a "there are x users on our IRC server" message on our website. Maybe there are others out there who might want to do the same, that's why I'm writing this mail. Till now I used php: $sock = fsockopen("localhost", 6667); fputs($sock, "nick IdleTest\r"); fputs($sock, "user idle . . :Idle-Test\r"); $result = fgets($sock, 4096); $result = fgets($sock, 4096); $result = fgets($sock, 4096); $result = fgets($sock, 4096); $result = fgets($sock, 4096); $result = fgets($sock, 4096); $n = sscanf($result, ":irc.server.url %d IdleTest :There are %d users %s", &$comid, &$users, &$rest); fputs($sock, "quit\r"); fclose($sock); $users--; //subtract the telnet connection echo "There are $users users on our IRC server"; It works but I found this solution unsatisfying so I changed the ngircd code and recompiled. I added/changed after line 365 BOOLEAN timeout; int alte_anz = -1; int anz_user = 0; FILE * fp_users; start = time( NULL ); while(( ! NGIRCd_SignalQuit ) && ( ! NGIRCd_SignalRestart )) { anz_user = Client_UserCount(); if(anz_user != alte_anz) { fp_users = fopen("/srv/www/htdocs/chat/chat.users", "w"); if(fp_users != NULL) { fprintf(fp_users, "%i\n", anz_user); fclose(fp_users); } alte_anz = anz_user; } timeout = TRUE; ... in conn.c after Check_Connections( ); so it will constantly write the number of users on the server to a file (in this case a file in the web directory) when the number changes. All the changes are between the timeout variable so you can easily find them. If you need more flexibility you could make the filename (and the whole piece of code) an additional option (I found no fitting free character for it (maybe -u filename?) and don't need the flexibility). BTW: Why is there --version and --help but not -v and -h? Hope you like it/can need it too. Yours, Jens

Problem with host resolving with ngircd
by Martin Hasenbein 26 Okt '04

26 Okt '04

Hi Everybody, I have a little problem with my resolving. My irc-server ran perfect the last few weeks, but yesterday I upgraded my BIND to 9.3.0 and today morning I recognized, that hosts are no longer resolved. Its just eg. mh(a)193.149.36.81 ... I'm really stuck right now. Upgrading my dns was the only thing I have done (the last time). Resolving itsself works fine (dig, rbl-lookups ...). ngircd seems to be the only daemon, that can't resolve anymore ... Any ideas are really appreciated!!! Thanks!

Copy & Paste flood protection?
by Khanh 16 Sep '04

16 Sep '04

Hi everyone, If I copy & paste 339 lines fo text, for example, I get disconnected with the following err msg from mIRC: * Send error ([10053] Software caused connection abort) With the IRCII daemon, there is a line in config.h where one define a limit (CLIENT_FLOOD). Unfortunately, the max byte count is 8000 and 339 lines of text is about 13000. How can I disable flood protection in ngircd? If this is not possible, any other daemons that will allow me to do so?

ngircd and IPv6?

Hi Alex, hi list, is there any IPv6-support for ngircd planned in the near future? Thanks!
