dircproxy - Detachable Internal Relay Chat Proxy Server

dircproxy [-hvDI] [-f config_file] [-P listen_port] [-p pid_file]

dircproxy is an IRC proxy server designed for people who use IRC from lots of different workstations or clients, but wish to remain connected and see what they missed while they were away.

You connect to IRC through dircproxy, and it keeps you connected to the server, even after you detach your client from it. While you're detached, it logs channel and private messages as well as important events, and when you re-attach it'll let you know what you missed.

This can be used to give you roughly the same functionality as using ircII and screen(8) together, except you can use whatever IRC client you like, including X ones!

Authentication is provided by a password, and optional hostname checking. This links it to a connection class specified in the configuration file. Only one user may use a connection class at one time, when that user detaches, the connection to the server is kept open. When someone (usually the user) subsequently connects to dircproxy and provides the same password, they are reconnected to the connection to the server, instead of having a new connection created for them.

Multiple connection classes can be defined, allowing multiple people to use the same proxy.

dircproxy can use either a .dircproxyrc file in the user's home directory, or a system-wide dircproxyrc file. It will load the first it finds (home directory first, then system-wide). If no configuration file is specified, it will not start.

-f config_file
Specifies the configuration file to be used, overriding the default search list.
-h
Displays a brief help message detailing the command-line arguments, then exits.
-v
Displays the dircproxy version number, then exits.
-D
Run in the foreground and do not fork into the background.
-I
Use to indicate dircproxy is being run from the inetd(8) daemon. This implies -D. For more information on running dircproxy under inetd(8), see the README.inetd file.
-P listen_port
Specifies an alternate port to use, overriding the default and any value specified in the configuration file. You can also add the IP-address of the adapter you want dircproxy to bind to, e.g.: 192.168.64.1:7007
-p pid_file
Specifies a file to write the process id to, overriding the default and any value specified in the configuration file.

The configuration file has the following format:

Empty lines and lines starting with '#' are comments.

Connection classes start with 'connection {' and end with '}'. They obtain default values from all the entries above them in the configuration file, and may contain values of their own.

Otherwise a line is of the format 'keywords arguments'. If the argument contains spaces it should be contained in double quotes ('"with spaces"'). The possible keywords and their meanings are as follows (note that the configuration file is not case-sensitive):

GLOBAL OPTIONS

These options may not be placed inside a connection class as they affect the operation of the entire dircproxy server.

listen_port
What port should dircproxy listen for connections from IRC clients on?

This can be a numeric port number, or a service name from /etc/services. You can also enter the IP-address of the adapter you want dircproxy to bind to, e.g.: 192.168.64.1:7007

pid_file
File to write the dircproxy process id to on startup. If you start this with a "~/" then it refers to a file in a directory under your home directory.

none = Don't write pid file

client_timeout
Maxmimum amount of time (in seconds) a client can take to connect to dircproxy and provide their password and nickname etc.

connect_timeout
Maximum amount of time (in seconds) a client has to provide a server to connect to after they've logged in. This only applies if 'server_autoconnect' is 'no' for that class.

dns_timeout
Maximum amount of time (in seconds) to wait for a reply from a DNS server. If the time exceeds this then the lookup is cancelled.

LOCAL OPTIONS

These options may be placed in a connection class, or outside of one. If they are outside then they only affect those connection classes defined afterwards.

SERVER OPTIONS

Options affecting the connection to the IRC server.

server_port
What port do we connect to IRC servers on if the server string doesn't explicitly set one

This can be a numeric port number, or a service name from /etc/services

server_retry
How many seconds after disconnection or last connection attempt do we wait before retrying again?

server_maxattempts
If we are disconnected from the server, how many times should we iterate the server list before giving up and declaring the proxied connection dead?

0 = iterate forever

server_maxinitattempts
On first connection, how many times should we iterate the server list before giving up and declaring the proxied connection dead?

0 = iterate forever. This isn't recommended.

server_keepalive
This checks whether the dircproxy to server connection is alive at the TCP level. If no data is sent in either direction for a period of time, a TCP keepalive probe is sent.

yes = send keepalive probes no = don't send keepalive probes

server_pingtimeout
For some people, dircproxy doesn't notice that the connection to the server has been dropped because the socket remains open. For example, those behind a NAT'd firewall. dircproxy can ping the server and make sure it gets replies back. If the time since the last reply was received exceeds the number of seconds below the server is assumed to be "stoned" and dircproxy leaves it. If you have a high latency connection to the server, it can wrongly assume the server is stoned because the PINGs don't arrive in time. Either raise the value, or use the 'server_keepalive' option instead.

0 = don't send PINGs

server_throttle
To prevent you from being flooded off the IRC network, dircproxy can throttle the connection to the server to prevent too much being sent within a certain time period.

For this you specify a number of bytes, then optionally a time period in seconds seperated by a colon. If the time period is ommitted then per second is assmued.

server_throttle 10 # 10 bytes per second server_throttle 10:2 # 10 bytes per 2 seconds (5 per second)

0 = do not throttle the connection

server_autoconnect
Should dircproxy automatically connect to the first server in the list when you connect. If you set this to 'no', then 'allow_jump' is automatically set to 'yes'. If 'allow_jump_new' is also 'yes', then you can create connection classes with no 'server' lines.

yes = Automatically connect to the first server no = Wait for a /DIRCPROXY JUMP from the client

CHANNEL OPTIONS

Options affecting channels you join.

channel_rejoin
If we are kicked off a channel, how many seconds do we wait before attempting to rejoin.

-1 = Don't rejoin 0 = Immediately

channel_leave_on_detach
Should dircproxy automatically make you leave all the channels you were on when you detach?

yes = Leave them no = Remain on them

channel_rejoin_on_attach
If 'channel_leave_on_detach' is 'yes' then should dircproxy rejoin those channels when you attach again?

yes = Rejoin the channels dircproxy automatically left no = Leave permanently on detach

IDLE OPTIONS

Options affecting idle times on IRC.

idle_maxtime
Set this to the maximum amount of time you want to appear idle for while on IRC, if you set this then dircproxy will reset your idle time if it reaches this limit (in seconds).

0 = Don't reset idle time

DISCONNECTiON OPTIONS

Options affecting when dircproxy disconnects you.

disconnect_existing_user
If, when you connect to dircproxy, another client is already using your connection class (ie, if you forgot to close that one), then this option lets you automatically kill that one off. Make sure you turn any "automatic reconnect to server" options off before using this, otherwise you'll have a fight on your hands.

yes = Yes, disconnect no = No, don't let me on

disconnect_on_detach
When you detach from dircproxy it usually keeps you connected to the server until you connect again. If you don't want this, and you want it to close your server connection as well, then set this.

yes = Close session on disconnection no = Stay connected to server until reattachment

MODE OPTIONS

Options affecting user modes set by the IRC server.

initial_modes
Which user modes should we automatically set when you first connect to a server. Just in case you forget to do it yourself with your irc client.

Set to "" to not set any modes.

drop_modes
Which user modes to drop automatically when you detach, handy to limit the impact that your client has while connected, or for extra security if you're an IRCop.

Set to "" to not drop any modes.

refuse_modes
Which user modes to refuse to accept from a server. If the server attempts to set one of these, then the connection to it will be dropped and the next server in the list will be tried.

A good setting for many people would be "+r", as most servers use that to mean your connection is restricted. Don't set it to this if you're on DALnet however, DALnet uses +r to indicate you have registered with NickServ (gee, thanks guys!).

Set to "" to not refuse any modes.

ADDRESS OPTIONS

Options affecting your address on IRC.

local_address
Local hostname to use when connecting to an IRC server. This provides the same functionality as the ircII -H parameter.

none = Do not bind any specific hostname

MESSAGE OPTIONS

Options affecting messages sent or set by dircproxy on behalf of you.

away_message
If you don't explicitly set an /AWAY message before you detach, dircproxy can for you, so people don't think you are really at your keyboard when you're not.

none = Do not set an away message for you

quit_message
If you don't explicitly give a message when you /DIRCPROXY QUIT, this will be used instead. Also used for when you've sent dircproxy not to remain attached to the server on detachment.

none = Use dircproxy version number as QUIT message

attach_message
dircproxy can send an announcement onto every channel you are on when you reattach to it, just to let everyone know you are back. If you start this with "/ME " then it will be sent as an ACTION CTCP message (just like the ircII /me command).

none = Do not announce attachment

detach_message
dircproxy can send an announcement onto every channel you are on when you detach from it, just to let everyone know you are gone. If you start this with "/ME " then it will be sent as an ACTION CTCP message (just like the ircII /me command).

none = Do not announce detachment

detach_nickname
Nickname to change to automatically after you detach, to indicate you are away for example. If this contains a '*' character, then that character is replaced with whataver your nickname was before you detached (ie "*_away" adds "_away" to the end of your nickname);

none = Leave nickname as it is

NICKNAME OPTIONS

Options affecting your nickname

nick_keep
Whether dircproxy should attempt to keep the nickname you last set using your client. If this is 'yes' and your nickname is lost while your client is disconnected, then it will keep on trying to get it back until a client connects again.

yes = try to keep my nickname while I'm disconnected no = if it changes, leave it

CTCP OPTIONS

Options affecting CTCP replies

ctcp_replies
Whether dircproxy should reply to the standard set of CTCP messages while the client is detached.

yes = reply to ctcp messages while client is detached no = nothing but silence

LOGGING OPTIONS

These options affect both the internal logging inside dircproxy so messages can be recalled to you when you return from being disconnected, and general logging for your own personal use.

log_timestamp
Log messages can have a timestamp added to the front to let you know exactly when a message was logged. The format of this timestamp depends on the setting of 'log_relativetime'.

yes = Include a timestamp in all log messages no = Do not include a timestamp

log_relativetime
If 'log_timestamp' is 'yes' then you have the option of using either intelligent relative timestamps, or ordinary fixed timestamps. If you choose relative, then the timestamp shown when log information is recalled to your client depends on how old that line is, with possible date information if it is a really old message. If you do not choose relative then only the time (in HH:MM format) will be logged.

This obviously has no effect on the log files under the directory specified by 'log_dir'.

yes = Use relative timestamps no = Use fixed timestamps

log_timeoffset
Difference in minutes from your IRC client to the dircproxy machine. So if you're in GMT, but your dircproxy machine is in PST (which is 8 hours behind), then this would be -(8 * 60) = -480. Used to adjust log file timestamps so they're in the right time zone for you.

0 = Don't adjust log timestamps.

log_events
Events you want dircproxy to log for you. This is a comma seperated list of event names, prefixed with '+' to add the event to the list or '-' to remove an event. You can also specify 'all' to log all events (the default) or 'none' to not log anything.

Example, to just log text and action's:

log_events "none,+text,+action"

Example, to log everything but server messages:

log_events "all,-server" # you don't need to specify 'all' log_events -server

The possible events are:

text Channel text and private messages

action CTCP ACTION events (/me) sent to you or channels

ctcp Whether to record whether a CTCP was sent to you

join People (including you) joining channels

part People (including you) leaving channels

kick People (including you) being kicked from channels

quit People quit'ing from IRC

nick People (including you) changing nickname

mode Changes in channel modes or your own personal mode

topic Changes to the channel topic

client You detaching and attaching

server Connections and disconnections from servers

error Problems and errors dircproxy encounters (recommended!)

log_dir
dircproxy keeps it's own internal log files (under /tmp) so it can recall information to your client when you reconnect. It can also log messages to files for your own use.

Under this directory a file will be created named after each channel you join, a file will be created named after each nickname that sends you private messages, or you send, and a final file called "server" will be created containing server events.

This logging is done regardless of the enabled or always settings, which only affect the internal logging. However the log_events settings do affect what is logged.

If you start with "~/" then it will use a directory under your home directory.

none = Do not create log files for your own use

log_program
Program to pipe log messages into. If given, dircproxy will run this program for each log message giving the full source information as the first argument, the destination as the second and the message itself as a single line on standard input.

The program can be anywhere in your $PATH, or you can start it with "~/" if its in a directory under your home directory.

This logging is done regardless of the enabled or always settings, which only affect the internal logging. However the log_events settings do affect what is logged.

none = Do not pipe log messages to a program

INTERNAL CHANNEL LOG OPTIONS

Options affecting the internal logging of channel text so it can be recalled to your client when you reconnect. These options only apply if the 'chan_log_enabled' option is set to 'yes'.

chan_log_enabled
Whether logging of channel text for later recall, so you can see what you missed, should take place.

yes = Channel text is logged for recall no = Channel text is NOT logged for recall

chan_log_always
Channel text will always be logged for later recall while you are offline, so when you come back you can see what you missed. You can also, if you wish, log channel text while you are online, so if you're only away a short time you can get an idea of any context.

yes = Log channel text for recall while offline and online no = Log channel text for recall only while offline

chan_log_maxsize
To preserve your harddisk space, you can limit the size of the internal channel log file, which is stored in the /tmp directory. Once the log file reaches this number of lines, every line added will result in a line being removed from the top. If you know you are never going to want all that logged information, this might be a good setting for you.

0 = No limit to internal log file size

chan_log_recall
Number of lines from the bottom of each internal channel log to automatically recall to your IRC client when you reconnect. If this is low, you may not get much useful information, if this is high, it may take a long time for all the information to arrive.

-1 = Recall the whole log (not recommended if chan_log_always is yes) 0 = Don't automatically recall anything

INTERNAL PRIVATE LOG OPTIONS

Options affecting the internal logging of private messages, notices, CTCP and DCC events so they can be recalled to your client when you reconnect. These options only apply if the 'private_log_enabled' option is set to 'yes'.

private_log_enabled
Whether logging of private messages for later recall, so you can see what you missed, should take place.

yes = Private messages are logged for recall no = Private messages are NOT logged for recall

private_log_always
Private messages will always be logged for later recall while you are offline, so when you come back you can see what you missed. You can also, if you wish, log private messages while you are online, so if you're only away a short time you can get an idea of any context.

yes = Log private messages for recall while offline and online no = Log private messages for recall only while offline

private_log_maxsize
To preserve your harddisk space, you can limit the size of the internal private message log file, which is stored in the /tmp directory. Once the log file reaches this number of lines, every line added will result in a line being removed from the top. If you know you are never going to want all that logged information, this might be a good setting for you.

0 = No limit to internal log file size

private_log_recall
Number of lines from the bottom of the internal private message log to automatically recall to your IRC client when you reconnect. If this is low, you may not get much useful information, if this is high, it may take a long time for all the information to arrive.

-1 = Recall the whole log (not recommended if private_log_always is yes) 0 = Don't automatically recall anything

INTERNAL SERVER LOG OPTIONS

Options affecting the internal logging of server messages so they can be recalled to your client when you reconnect. These options only apply if the 'server_log_enabled' option is set to 'yes'.

server_log_enabled
Whether logging of server messages for later recall, so you can see what you missed, should take place.

yes = Server messages are logged for recall no = Server messages are NOT logged for recall

server_log_always
Server messages will always be logged for later recall while you are offline, so when you come back you can see what you missed. You can also, if you wish, log server messages while you are online, so if you're only away a short time you can get an idea of any context.

yes = Log server messages for recall while offline and online no = Log server messages for recall only while offline

server_log_maxsize
To preserve your harddisk space, you can limit the size of the internal server message log file, which is stored in the /tmp directory. Once the log file reaches this number of lines, every line added will result in a line being removed from the top. If you know you are never going to want all that logged information, this might be a good setting for you.

0 = No limit to internal log file size

server_log_recall
Number of lines from the bottom of the internal server message log to automatically recall to your IRC client when you reconnect. If this is low, you may not get much useful information, if this is high, it may take a long time for all the information to arrive.

-1 = Recall the whole log (not recommended if server_log_always is yes) 0 = Don't automatically recall anything

DCC PROXY OPTIONS

Options affecting proxying and capturing of DCC chat and send requests.

dcc_proxy_incoming
Whether dircproxy should proxy DCC chat and send requests sent to you by others on IRC.

yes = Proxy incoming requests. no = Do not proxy incoming requests.

dcc_proxy_outgoing
Whether dircproxy should proxy DCC chat and send requests sent by you to others on IRC.

yes = Proxy outgoing requests. no = Do not proxy outgoing requests.

dcc_proxy_ports
Ports that dircproxy can use to listen for DCC connections on. This is for when you're behind a firewall that only allows certain ports through, or when doing DCC-via-ssh.

It is a comma seperated list of port numbers or ranges of ports, for example '57100-57199,57400,57500,57600-57800'

any = Use any port given to us by the kernel.

dcc_proxy_timeout
Maxmimum amount of time (in seconds) to allow for both sides of a DCC proxy to be connected.

dcc_proxy_sendreject
Whether to send a physical REJECT message via CTCP back to the source of the request in event of failure.

yes = Send reject CTCP message back. no = Do not send any message back.

dcc_send_fast
Whether to ignore the "acknowledgment" packets from the client and just send the file to them as fast as possible. There should be no real danger in doing this.

yes = Send as fast as possible. no = Wait for each packet to be acknowledged.

dcc_capture_directory
dircproxy can capture files sent via DCC and store them on the server. Especially useful while you are detached, whether it does it while attached or not depends on 'dcc_capture_always'. This is the directory to store those captured files in.

If start with "~/" then it will use a directory under your home directory.

none = Do not capture files.

dcc_capture_always
If we're capturing DCC send's, should we do it while the client is connected as well? If 'yes', then the client will never see the file, it'll be just stored on the server with a notice sent to the client telling them where.

yes = Capture even when a client is connected. no = Capture only when client detached.

dcc_capture_withnick
Whether to start the filename of the captured file with the nickname of the sender, so you know who it came from.

yes = Start with nickname. no = Do not alter the filename.

dcc_capture_maxsize
Maximum size (in kilobytes) that a captured file can be. If a captured file is larger than this, or becomes larger than this, then the capture will be aborted and the file removed from the disk. Prevents people from filling your disk up while you're detached with a massive file.

0 = No limit to file size.

dcc_tunnel_incoming
Port of a local ssh tunnel leading to another dircproxy client that we should use for incoming DCC requests. This should not be set if 'dcc_tunnel_outgoing' is set.

See the README.dcc-via-ssh file included with the dircproxy distribution for more information.

This can be a numeric port number, or a service name from /etc/services

none = There is no tunnel.

dcc_tunnel_outgoing
Port of a local ssh tunnel leading to another dircproxy client that we should use for outgoing DCC requests. This should not be set if 'dcc_tunnel_incoming' is set.

See the README.dcc-via-ssh file included with the dircproxy distribution for more information.

This can be a numeric port number, or a service name from /etc/services

none = There is no tunnel.

ADVANCED OPTIONS

Options for the advanced user.

switch_user
If you're running dircproxy as root, it can switch to a different "effective user id" to create the server connection. This means that your system ident daemon (and therefore IRC, if it queries it) will see your server connection as the user you put here, instead of root.

This is most useful if you are sysadmin running a dircproxy server for multiple people and want them to all appear as different usernames without using a hacked identd. Because dircproxy is still running as root, it will have those privileges for all operations, including the bind(2) for the 'local_address' config option if you're using Secure Linux patches.

This can only be used if your system supports seteuid(2) and if you are running dircproxy as the root user, and not just setuid. Attempting otherwise will generate a warning as dircproxy starts.

This can be a numeric uid or a username from /etc/passwd.

none = Do not do this.

MOTD OPTIONS

Options affecting the dircproxy message of the day.

motd_logo
If this is yes, then the dircproxy logo and version number will be included in the message of the day when you connect. Only the picky would turn this off, its pretty!

yes = Show me the pretty logo no = I don't like logos, I'm boring, I eat llamas.

motd_file
Custom message of the day file to send when users connect to dircproxy. The contents of this file will be sent after the logo and before the stats. If you start this with a "~/" then it refers to a file in a directory under your home directory.

none = No custom motd

motd_stats
Display information on what channels you were on, and log file sizes etc in the message of the day. This is handy, and lets you know how not only much information you missed, but how much will be sent to you.

yes = Show the stats no = They don't interest me, don't show them.

COMMAND OPTIONS

Options allowing or disallowing the use of /DIRCPROXY commands.

allow_persist
You can disable the /DIRCPROXY PERSIST command if you do not want people using your proxy to be able to do that.

yes = Command enabled no = Command disabled

allow_jump
You can disable the /DIRCPROXY JUMP command if you do not want people to do that.

yes = Command enabled no = Command disabled

allow_jump_new
If the /DIRCPROXY JUMP commmand is enabled, then you can disable it being used to jump to a server:port not in the list specified in the configuration file.

yes = Can jump to any server no = Only ones in the config file

allow_host
You can disable the /DIRCPROXY HOST command if you do not want people to do that.

yes = Command enabled no = Command disabled

allow_die
You can enable the /DIRCPROXY DIE command if you want people to be able to kill your proxy. This isn't recommended as a global option, instead only enable it for a specific connection class (ie yours).

yes = Command enabled no = Command disabled

allow_users
You can enable the /DIRCPROXY USERS command if you want people to be able to see who's using your proxy. This isn't recommended as a global option, instead only enable it for a specific connection class (ie yours).

yes = Command enabled no = Command disabled

allow_kill
You can enable the /DIRCPROXY KILL command if you want people to be able to disconnect anyone using your proxy (including you!). This isn't recommended as a global option, instead only enable it for a specific connection class (ie yours).

yes = Command enabled no = Command disabled

allow_kill
You can enable the /DIRCPROXY NOTIFY command if you want people to be able to send a notice to anyone using your proxy (including you!). This isn't recommended as a global option, instead only enable it for a specific connection class (ie yours).

yes = Command enabled no = Command disabled

Additionally, the following keywords may go only inside a connection class definition. One 'password' and at least one 'server' (unless 'server_autoconnect' is 'no' and 'allow_jump_new' is 'yes') are mandatory.

password
Password required to use this connection class. This should be encrypted using your system's crypt(3) function. It must be the same as the password supplied by the IRC client on connection for this connection class to be used.

You can use the included dircproxy-crypt(1) utility to generate these passwords.

server
Server to connect to. Multiple servers can be given, in which case they are iterated when the connection to one is dropped. This has the following format:

[hostname[:[port][:password]]

from
The connection hostname must match this mask, multiple masks can be specified to allow more hosts to connect. The * and ? wildcards may be used.

join
Channels to join when you first connect. Multiple channels can be given, either by seperating the names with a comma, or by specifying multiple from the channel name with a space.

Note: You must surround the list of channels with quotes to distinguish from comments.

For clarification, this is the format of this line:

join "channel[ key][,channel[ key]]..."

dircproxy will reread its configuration file whenever it receives the hangup signal, SIGHUP.

Sending an interrupt signal, SIGINT, or a terminate signal, SIGTERM, will cause dircproxy to exit cleanly.
