this patch contains:
* Fix for Conf_CloakUserToNick to make it conceal user details
* Adds MorePrivacy-feature
MorePrivacy censors some user information from being reported by the
server. Signon time and idle time is censored. Part and quit messages
are made to look the same. WHOWAS requests are silently dropped. All
of this is useful if one wish to conceal users that access the ngircd
servers from TOR or I2P.
This patch makes it possible to scrub incomming CTCP commands from
other servers and clients alike. The ngircd oper can enable it from
the config file, by adding "ScrubCTCP = yes" under [OPTIONS]. It is
default off.
CTCP can be used to profile IRC users (get user clients name and
version, and also their IP addresses). This is not something we like
to happen when user pseudonymity/secrecy is important.
The server silently drops incomming CTCP requests from both other
servers and from users. The server that scrubs CTCP will not forward
the CTCP requests to other servers in the network either, which can
spell trouble if not every oper knows about the CTCP-scrubbing.
Scrubbing CTCP commands also means that it is not possible to send
files between users.
There is one exception to the CTCP scrubbing performed: ACTION ("/me
commands") requests are not scrubbed. ACTION is not dangerous to users
(unless they use OTR, which does not encrypt CTCP requests) and most
users would be confused if they were just dropped.
A CTCP request looks like this:
ctcp_char, COMMAND, arg0, arg1, arg2, .. argN, ctcp_char
ctcp_char is 0x01. (just like bold is 0x02 and color is 0x03.)
They are sent as part of a message and can be delivered to channels
and users alike.
The intention of this restructuring is to make the [Global] section much
cleaner, so that it only contains variables that most installations must
adjust to the local requirements.
All the optional variables are moved to [Limits], for configurable limits
and timers of ngIRCd, and [Options], for optional features.
The old variables in the [Global] section are deprecated now, but still
recognized.
The io_event_create error handling seems to miss a 'return'
statement.
Fix this by moving io_event_create() call around so we do not
need the Conn_Close/Init calls in the error case.
problem is that some clients refuse to connect to severs that only offer
1024. For interoperability it would be best to just use 4096, but that
takes minutes, even on current hardware.
parse.c:284: warning: suggest parentheses around operand of '!' or
change '&' to '&&' or '!' to '~'
The expression looks dubious, this should probably be
an if-not-set, then... test.
When the write buffer space grows too large, ngircd has to disconnect
the client to avoid wasting too much memory.
ngircd logs this with a scary 'write buffer overflow' message.
Change this to a more descriptive wording.
Not all servers (and services!) using the RFC1459 protocol style send
prefixes on all commands; so don't require them to do so.
This relaxes the requirements introduced by commit 15775e679.
We re-use the same helper function for both forward lookups
(when we want to connect to a peer server) and for validation of reverse
loopups (where we make a lookup on the hostname returned
by a reverse lookup on the IP address that connected).
Problem:
When ConnectIPv6=no, the forward lookup helper sets the adderss family
to AF_INET, and, if out client connected via ipv6, we fail to validate
the result.
Thus move the ConnectIPvX check out of the helper.
we do not need this for cryptographic purposes, but we can do better
than plain srandom(getpid()).
Also, keep in mind that rng state is inherited across fork(), so re-init
it in the child.
When enabled, this configuration option lets ngIRCd send a PING with an
numeric "token" to clients logging in; and it will not become registered
in the network until the client responds with the correct PONG.
This is used by QuakeNet for example (ircu/snircd), and looks like this:
NICK nick
:irc.example.net PING :1858979527
USER user . . :real name
PONG 1858979527
:irc.example.net 001 nick :Welcome to the Internet Relay Network ...
Make sure that all commands received from other servers do have
valid prefixes.
Only exceptions are PING and ERROR commands that can occure without
prefixes when generated by the remote peer itself.
* CloakUserHost:
Add a note not to use a percent sign ("%") in CloakHost variable
Rename ClientHost to CloakHost, and ClientUserNick to CloakUserToNick
Don't use "the.net" in sample-ngircd.conf, use "example.net"
ngircd.conf.5: document "ClientHost" and "ClientUserNick"
Move "ClientHost" and "ClientUserNick" to end of [Global] section
ClientUserNick setting
ClientHost setting
* QuitOnHTTP:
Only "handle" HTTP commands on unregistered connections
Don't use IRC_QUIT_HTTP() if STRICT_RFC is #define'd
IRC_QUIT_HTTP(): enhance error message
Move IRC_QUIT_HTTP() below IRC_QUIT()
quit on HTTP commands: GET & POST
* bug72-WHOIS-List:
Add "whois-test" to testsuite and distribution archive
Add support for up to 3 targets in WHOIS queries.
also allow up to one wildcard query from local hosts.
Follows ircd 2.10 implementation rather than RFC 2812.
At most 10 entries are returned per wildcard expansion.
WHOIS test cases by Dana Dahlstrom.
previously, any client could join in this configuration:
[Channel]
Name = #test
Modes = tnk
KeyFile = /tmp/foobar
fix this by checking for zero-length key before comparing
key to channel key.
This fixes the followin GCC warning on modern Linux systems as well:
irc-login.c: In function ‘Hello_User’:
irc-login.c:876: warning: ignoring return value of ‘write’,
declared with attribute warn_unused_result
This patch
- makes the server write buffer bigger: 64k,
- makes the regular write buffer bigger: 32k,
- tries to flush the write buffer starting at 4K.
Before this patch, a client got disconnected if the buffer flushing at 4k
failed, now regular clients can store up to 32k and servers up 64k even
if flushing is not possible at the moment (e.g. on slow links).
Don't do a NULL-pointer dereference when a remote server using the
IRC+ protocol sends an invalid PASS command without the required
<serverversion> parameter ...
Port number 0 marks remote servers that try to connect to this
daemon, but where this daemon never tries to establis a connection
on its own: only incoming connections are allowed.
Don't use isdigit() function any more, because it only checks the
first character of the variable value and because it doesn't know
about the minus sign which is required e.g. for "Group = -1".
The MOTD file is read in Read_Config(), so don't read it when handling
the "MotdFile" configuration variable. Instead make sure that it is
initialized properly when (re-)reading the configuration.
Fix commit 5a34bb203a:
It is not enough to strip the "No" prefix from "Ident" and "PAM",
but we have to introduce the new [Features] section to fix all
warning messages of ngIRCd.
Variables "Ident" and "PAM" in [Global] are completely wrong :-(
This enables other servers, services and IRC operators to change
channel topics, even when the client is not joined to this channel.
Now the handler for TOPIC behaves like the one for MODE.
This generic function tests if a client is allowed to do administrative
tasks to a specific channel:
- servers and services are always truested ("allowed everything"),
- channel operators are allowed,
- IRC operarors are allowed if OperCanUseMode is set in the config.
libc should know better than us.
Also, this helps debugging with tools like valgrind:
When you allocate an array of size x, and then erronoulsy
use x+1 valgrind cannot detect the bug because due to ALIGN_()
made by array.c we might have allocated more than size x...
ngircd unfortunately uses several options using double-negation, e.g.
NoIdent = No, NoPam = No, etc.
This renames all options by dropping the "No" prefix, e.g.
"NoIdent = no" becomes "Ident = yes".
The old options will continue to work, but will cause a warning
message.
Also update man pages and default config.
To prevent silly
'Ident = yes' from appearing in --configtest output in the
'ident support not compiled in and Ident Option not used' case,
make default value depend on feature availability.
If feature is available, enable by default, otherwise disable.
We might consider moving these options to a new
[Feature]
section, or something like that, because none of these options are
essential.
Another possible improvement:
'Ident = yes' option in ngircd.conf causes a warning if ngircd was
built without ident support.
This does not happen with e.g. zeroconf....
Configuration variables "MotdFile" and "MotdPhrase" are mutually
exclusive; so don't display content in both of them when running
"ngircd --configtest": instead remember which one is beeing used.
The information written to the "error file" (/tmp/ngircd-<PID>.err) when
ngIRCd is compiled with debug code enabled isn't that usefule, so don't
create this file at all.
If a hostname resolves to more than one IP address (round-robin DNS,
IPv4 and IPv6) and an attempt to connect to the first address fails,
ngIRCd should try to connect to the 2nd address, 3rd address etc.
But because of a wrong variable used in the call to New_Server(),
the wrong server structure has been used in further connection attemps
which possibly lead to connection attempts to already connected servers.
disable pam_fail_delay() only is available starting with Mac
OS X 10.6; but we use the 10.5 SDK for campatibility, so don't use
this function at all when building using Xcode.
This allows to compile ngIRCd using a pre-ANSI K&R C compiler again:
all source files are automatically converted by the included ansi2knr
program (of GNU automake/autoconf) before compiling them with the
K&R C compiler, but a few coding standards must be met.
Tested on Apple A/UX 3.x.
Regression testing on Linux and Mac OS X.
If ngIRCd is compiled to register its services using ZeroConf (e.g. using
Howl, Avahi or on Mac OS X) this parameter can be used to disable service
registration at runtime.
This fixes the following gcc compiler warning:
tool.c: In function 'ngt_SyslogFacilityName':
tool.c:195: warning: return discards qualifiers from pointer target type
The new option "SyslogFacility" deines the syslog "facility" to which
ngIRCd should send log messages.
Possible values are system dependant, but most probably "auth", "daemon",
"user" and "local1" through "local7" are possible values; see syslog(3).
Default is "local5" for historical reasons.
These both functions translate syslog facility names to ID numbers
and vice versa. On systems that don't define the facilitynames[] array
in syslog.h, we try to build one ourself.
This fixes the following gcc warning, emitted by Xcode:
src/ngircd/sighandlers.c: In function 'Signal_Callback':
src/ngircd/sighandlers.c:239: warning: implicit conversion shortens 64-bit value into a 32-bit value
Signals_Init() must only be called once.
This does not affect any ngircd release version.
Earlier version of this patch moved the io and sighandler
initialization before the while() loop, but as Alexander
Barton noticed that broke all systems without builtin select
support in io.c...
- declare signals_catch[] array not between the function implementations.
- rename now local function NGIRCd_Rehash() to Rehash().
- remove empty and therefore not used "catch SIGHUP; break;".
This patch allows ngIRCd to dump its internal state (connected clients,
actual configuration) when compiled with --enable-debug. The daemon
catches two more signals:
- SIGUSR1: toggle debug mode (on/off),
- SIGUSR2: dump internal state to console/syslog.
now that the main signal handling is done from the dispatcher
loop we can call NGIRCD_Rehash() directly.
the /REHASH handler can queue the Rehash() function for
execution by sending a SIGHUP. It will be run when we
return back to the dispatch loop.
Allows to defer/queue signal processing for execution on the next
event dispatch call, i.e. we can perform any signal action in
normal, non-signal context.
Example uses:
- Reload everything on HUP without writing a global "SIGHUP_received"
variable
- Dump status of internal Lists on SIGUSR1, etc.
Fix synchronization of established connections and configured server
structures after a configuration update:
- Not only test servers that already have a connection, but also check
and update configured servers to which a new connection is beeing
established (SERVER_WAIT state).
- And do the server name comparision case-insensitive.
Let CheckServers() not only skip servers that already have a
connection, but also skip servers to which a new connection is
already beeing established (SERVER_WAIT state).
This fixes PING-PONG lag calculation (which resulted in "0" before).
The "lastping" time is still reset it if a time shift backwards has
been detected to prevent the daemon from miscalculating ping timeouts.
When a client has user mode "x" set, its real hostname is cloaked
by substituting it with the server name (as configured in ngircd.conf).
Restricted clients (user mode "r") aren't allowed to change mode "x".
Please note that hostname cloaking is only in effect in server-client
communication! The server still uses the real hostname for its own
logging and for all server-server communication -- therefore all servers
in the network must support user mode "x" to prevent older servers
from leaking the real hostname of a cloaked client!
These two functions return the cloaked hostname, if the client has
enabled hostname cloaking indicated by the -- still to implement --
user mode "x". See furter patches :-)
previously, the given MotdFile file was read whenever a client
requested it.
Change handling to read the MotdFile contents into memory once
during config file parsing.
Two side effects:
- changes to the MOTD file do not have any effect until ngircds
configuration is reloaded
- MOTD file does no longer have to reside in the chroot directory
(the MOTD contents will then not be re-read on reload in that case)
This avoids a race and potentionally killing the wrong process on
systems that use randomized process IDs; now the child itself is
responsible to exit in a timely manner using SIGALRM.
Some variables are only used when compiling with IDENT or PAM support
or when the debug code is enabled. Mark them as "unused" so that gcc
doesn't generate warnings when neither of these options is enabled.
When the "NoPAM" configuration option is set and ngIRCd is compiled
with support for PAM, ngIRCd will not call any PAM functions: all
connection attemps without password will succeed instead and all
connection attemps with password will fail.
If ngIRCd is compiled without PAM support, this option is a dummy
option and nothing changes: the global server password will still be
in effect.
For each client connection a child process is forked which handles the
actual PAM authentication and reports the result back to the master
process using a pipe for communication.
While the PAM authentication is in process the daemon does not block.
The Client_SetOrigUser() function is used to store the peer-provided
user name (see USER command) in its original form, not changed by
IDENT results, for example.
Rename Log_Init_Resolver, Log_Exit_Resolver, and Log_Resolver to
Log_Init_Subprocess, Log_Exit_Subprocess, and Log_Subprocess and
make it more generic thereby.
The logic isn't as described in the source and intended by this code:
ngIRCd doesn't wait for the asynchronous resolver process until the set
penalty time is over, but until the forked process terminates or the
initial connection timeout (= PongTimeout) triggers.
So don't set the penalty time at all and remove the wrong comment.
We want to use this process status variable not only for the
resolver subprocesses but other asynchronous tasks as well;
so let's name it more generic.
The new "module" proc.c is used for functions dealing with child
processes. At the moment, it is only used by the asynchronous resolver.
All the functions already implemented habe been migrated from the
resolver code base, and the rest of the ngIRCd source code has been
adepted to the new namespace and calling conventions.
The goal is to develop "generic" process handling functions that can
be used for other purposes as well, e.g. running processes on client
connects etc.
The wrongly placed #endif lead to the following compiler warnings:
conn.h:125: warning: redundant redeclaration of ‘Conn_Count’
conn.h:125: warning: previous declaration of ‘Conn_Count’ was here
conn.h:126: warning: redundant redeclaration of ‘Conn_CountMax’

Users having the user mode "c" set receive NOTICE messages on each
new client connection to the local server as well as disconnects.
Only IRC operators (users having the mode "o" set) are allowed to
set the 'c' user mode.
These connect/disconnect messages can be useful for open proxy
scanners -- BOPM (http://wiki.blitzed.org/BOPM) is now functional
with ngIRCd, for example.
"I've been wanting this for years and finally took the 5 minutes to
patch it in. I took the response code (275) from whatever's running
OFTC's IRC network."

(OFTC is running Hybrid ircd.)
It is not possible to call Conn_Close() after Client_Destroy() has been
called, because Conn_Close wants to access the CLIENT structure which
then has been freed already.
Fix IRC_KILL to use Conn_Close() for local clients and Client_Destroy()
for remote clients only (and never both).
When we get there then the ssl handshake has failed, or
we could not create a ssl context because ssl library
initialization failed on startup.
Reflect that in the log message.
When ngIRCd restarts, all the connection counters are preserved now,
as well as the command counters for example.
It's unclear if resetting or not resetting is the "correct" behaviour,
but it's quite clear that the behaviour should be consistent for all the
counters ngIRCd uses ...
And initializing "WCounter", the global but temporary write counter,
is not necessarry at all: it is initialized (reset) before its use in
the command parser (see parse.c).
The RPL_STATSCONN numeric (250) displays information about the
highest simoultaneous connection count and the number of all
accepted connections since the daemon started up.
Used by ircd-Hybrid, Bahamut, and Unreal for example.
This patch enables ngIRCd to count the highest maximum simultaneous
connections and all the connections accepted since startup.
New functions:
- Conn_Count(): get current connections
- Conn_CountMax(): maximum simultaneous connections
- Conn_CountAccepted(): number of connections accepted
This fixes the following error when compiling on e.g. FreeBSD 6.x:
In file included from conn.c:40:
/usr/include/netinet/ip.h:160: error: syntax error before "n_long"
/usr/include/netinet/ip.h:163: error: syntax error before "n_long"
This patch fixes two warnings of gcc 4.4.3 when used with eglibc 2.11.1:
ngircd.c: In function ‘NGIRCd_Init’:
ngircd.c:801: warning: ignoring return value of ‘chdir’, declared with
attribute warn_unused_result
conn.c: In function ‘Simple_Message’:
conn.c:2041: warning: ignoring return value of ‘write’, declared with
attribute warn_unused_result
The first by checking the return code and an appropriate error message,
the second by "better" ignoring it (which is correct there!) ...
The WEBIRC command is used by some Web-to-IRC gateways to set the correct
user name and host name of users instead of their own.
Syntax: WEBIRC <password> <username> <hostname> <ip-address>
The <password> must be set using the new configuration variable "WebircPassword" in the [Global] section of ngircd.conf.
Please note that the <ip-address> is currently not used by ngIRCd (we don't store it in the CLIENT structure, only the resolved hostname).
Only clients using a SSL encrypted connection to the server are
allowed to join such a channel.
But please note three things:
a) already joined clients are not checked when setting this mode,
b) IRC operators are always allowed to join every channel, and
c) remote clients using a server not supporting this mode are not
checked either and therefore always allowed to join.
Now the numeric 004 correctly reports all the supported user and channel
modes (user modes "r" and "w" were missing), e. g.:
:a.irc.net 004 a a.irc.net ngircd-15 aiorsw biIklmnoPstv
Print "SSLOptionVar =" instead of omitting the option when
running --configtest with ssl enabled.
This better matches the behaviour of other options, e.g. ChrootDir.
This patch enables IRC Operators to use the SQUIT command as specified in
RFC 2812, section 3.1.8 "Squit".
When forwarding SQUIT commands, the server connected to the target will
drop the connection (not the target server itself!).
Please note:
- the configuration option "AllowRemoteOper" mus be enabled on the
server disconnecting the target to allow forwarding of SQUIT commands.
- if the remote server is configured to establish the connection, it
will just do this; so the disconnect is not permanent in this case!
The new "module" op.c is used to implement functions related to IRC Ops.
At the moment, these two functions are available:
- Op_Check() to check for a valid IRC Op, and
- Op_NoPrivileges() to generate "permission denied" messages.
The syntax of the CONNECT command now is:
- CONNECT <server-id>
- CONNECT <server-id> <port>
- CONNECT <server-id> <port> <target>
- CONNECT <server-id> <port> <host> <my-pwd> <peer-pwd>
- CONNECT <server-id> <port> <host> <my-pwd> <peer-pwd> <target>
Note: the configuration option "AllowRemoteOper" mus be enabled on the
target server to allow forwarding of CONNECT commands.
Added new configuration option "AllowRemoteOper" to control whether
remote IRC operators are allowed to use administrative commands that
affect this server or not
This commit introduces the configuration variable, but actually no
function is using it. That's up for the next patches to come ...
when building with debugging enabled, but without ipv6 support,
ngircd dumped core when loading a config file that specified an ipv6
listen address.
ngircd: ng_ipaddr.c:45: ng_ipaddr_init: Assertion `sizeof(*addr) >=
res0->ai_addrlen' failed.
Test for sockaddr_in.sin_len and initialize it to the correct value
which some systems (notably Mac OS X) require.
Note: this code path is only relevant when not using getaddrinfo().
A configured server could have been removed while a connection apptempt
is still in progress. So the cb_connserver() callback has to test if the
server configuration record is still valid.
fix the following warning generated by valgrind if ipv6 is enabled:
Syscall param write(buf) points to uninitialised byte(s)
at 0x4000982: (within /lib/ld-2.9.so)
by 0x80681A8: Resolve_Name (resolve.c:477)
by 0x805439F: Conn_Handler (conn.c:1658)
by 0x804AA7C: main (ngircd.c:331)
The warning is because ng_ipaddr_t can be a union, and only the
necessary parts are initialised. The callers know what part
of the union is valid, so this is not a bug.
if more than one ip address is returned for a single host
name, ngircd is supposed to try other addresses in case
connect() to the first address returned fails for some
reason.
Alexander Barton noticed that this did not work at all,
as the additional results were not stored.
Cosmo Kastemaa reported that its impossible to create an ssl-only setup,
as ngircd binds to port 6667 by default, even if setting "Ports =".
Only add the default port if _both_ "Ports" and "SSLPorts" are
unspecified.
Fixes bugzilla #98.
This patch fixes the following silly log messages:
'ID "XXX" already registered (on connection -1)!'
If the ID is already registered on a local connection, the local
connection ID is printed; and if the ID is connected via a remote
server, "via network" is displayed.
reported on #ngircd: pasting lots of lines into a channel can kill off
many people on the channel if the read buffer is drained quickly enough
and the client-side TCP can't keep up with the incoming data.
This implements a throttling scheme:
- an irc client may send up to 3 commands per second before a one second
pause is enforced.
- an irc client may send up to 256 bytes per second before a one second
pause is enforced.
After discussion with Alexander Barton, server <-> server links are
treated specially: There is no artificial limit on the number of bytes
sent per second, and up to 10 commands are processed per second before
a pause is enforced.
It may be neccessary to make those limits tuneable to accomondate larger
networks, but for now they are compile time values.
New_Server() can call Conn_Close() in its error paths,
but that function decrements the number of current active
connections. Thus we need to increment it earlier.
When a server is running with SSL/TLS support compiled in,
it is trivial to crash the server by sending an MOTD request
via another server in the network.
- ONLY servers without ssl/tls support compiled in are not affected.
Disabling SSL in the configuration (no ssl listening ports, etc)
does NOT help.
- servers that are running standalone (i.e., not connected to any
other servers) are not affected, either.
This affects all ngircd releases since ngircd 13 (earlier versions
have no SSL/TLS support).
When ngircd announces the list of currently known servers
to a new (connecting) server, it sent the introducer of
the servers instead of the top server.
Assuming this network:
irc1.example.com
|--irc2.example.com
| `--irc3.example.com
| `--irc4.example.com
`--irc5.example.com
When irc4 connects to irc3, irc3 tells irc4 that irc5 was
connected to irc2. (irc2 had introduced irc5 to irc3; but thats
not what ngircd should have sent to the new server).
This also placed users on the wrong servers.
that code does not really make sense -- the info
text is freely cofngiureable and des not follow a specific
format.
Also, that "+2" might have caused invalid memory accesses.
With this patch ngIRCd displays IPv6 addresses as "[<addr>]:<port>" when
accepting new connections and later, if no successful DNS lookup could
be made (or DNS is disabled altogether).
Don't echo multiple syntax error messages (461) on invalid commands,
but break after the first one.
In addition, this solves corrupted 'Unknown mode "+' messages.
When using OpenSSL, the following annoying "error" message was logged whenever
an encrypted connection was shut down in a orderly fashion:
TLS/SSL Connection shutdown: ConnSSL_Read: Unable to determine error
of course, this isn't an error at all.
commit 6bc2d3d06e
(New connection option CONN_RFC1459) forgot to adjust the ssl bitmasks.
The result is that when a compressed AND encrypted server link goes down
the memory allocated by zlib and the r/w buffers are no longer
free'd as the previous ConnSSL_Free() would then also remove the CONN_ZIP flag
from the flag mask.
Store the file name of channel key files and reopen them on each access
(on each JOIN command) insted of just storing the file handles.
This eliminates the special requirements (no delete) and makes sure
that always the actual file contents are used in all circumstances.
This patch introduces the new configuration variable "KeyFile" for
[Channel] sections in ngircd.conf. Here a file can be configured for each
pre-defined channel which contains individual channel keys for different
users. This file is line-based and must have the following syntax:
<user>:<nick>:<key>
<user> and <nick> can contain the wildcard character "*".
Please not that these channel keys are only in effect, when the channel
has a regular key set using channel mode "k"!
commit 2546a13ad2
('Cumulative Message Patch') broke PRIVMSG to channels
containing dots.
Fix this by switching evaluation order:
Check first if the target matches a existing channel and only do a check
for target masks if that failed.
PRIVMSG with host/server masks is described in RFC 2812, section 3.3.1.
Makes one wonder how a server is _really_ supposed to tell the difference
between hostmasks and channel names.
Sigh.
when ngircd is build without DEBUG enabled, LOG_DEBUG messages
are always discarded.
To avoid the extra code, ngircd has a LogDebug() wrapper which
gets removed by the compiler when compiling without DEBUG defined.
Update a few functings which were using the
Log(LOG_DEBUG, .. interface directly without #ifdef DEBUG guards.

This patch fixes the following warning of GCC (version 4.3.2) in
function pem_passwd_cb() when compiling with OpenSSL support and
without debug code:
conn-ssl.c: In function 'pem_passwd_cb':
conn-ssl.c:122: warning: unused parameter 'rwflag'
The new configuration option "NoIdent" in ngircd.conf can be used to
disable IDENT lookups even when the ngIRCd daemon is compiled with IDENT
lookups enabled.
The IRC command "SERVLIST" lists all the registered services, see RFC 2811, section 3.5.1.
The syntax is "SERVLIST [<mask> [<type>]]". The parameter <type> is not used by ngIRCd at
the moment, all registered services are of type 0 (which is the default when omitted).
ngIRCd now creates a server-local channel &SERVER with channel modes
+mnPt (moderated, no messages from outside the channel, persistent and
with the topic locked) and logs all the messages to it that a user with
mode +s ("server messages") receives.
If an IRC operator withdraws the +P ("persistent") mode and the &SERVER
channel is freed because of no members, nothing special happens. The
channel can be recerated any time later and ngIRCd would begin logging
to it again.
The following bits and bytes were not included in distribution archives:
- contrib: ngindent, ngircd.sh
- contrib/Debian: ngircd.postinst
- contrib/MacOSX: preinstall.sh, postinstall.sh
- doc/src: Doxyfile, header.inc.html, footer.inc.html, ngircd-doc.css
- src/portab: splint.h
I changed the test suite to start two test servers (on port 6789 and 6790),
so server-server links can be tested as well for which I included the new
test script "server-link-test.e".
In addition the documentation of the test suite (src/testsuite/README) has
been updated and is more complete now.
This patch lets ngIRCd count outgoing connections as well as incoming
connections (up to now only outgoing connections have been counted). This
change is required because the Conn_Close() function doesn't know whether
it closes an outgoing connection or not and therefore would decrement the
counter below zero when an outgoing connection existed -- which would
trigger an assert() call ...
Please note that this patch changes the (so far undocumented but now fixed)
behaviour of the "MaxConnections" configuration option to account the sum
of the in- and outbound connections!
Some servers send the numeric 020 ("please wait while we process your
connection") when a client connects. This is no useful information for
this server, so we simply ignore it :-)
This patch enables ngIRCd to use GNUTLS in really old versions, tested
with version 1.0.16, that don't define the "new" data types ending in
xxx_t. LIBGNUTLS_VERSION_MAJOR isn't defined there as well, so we use
it to test if we must define the new types on our own.
