Abstract
--------
ii is a minimalistic FIFO and filesystem based IDC client. It creates an idc
directory tree with server, channel and nick name directories. In every
directory a FIFO file (in) and normal file (out) is placed.

The in file is used to communicate with the servers and the out files include
the server messages. For every channel and every nick name there will be new in
and out files.

The basic idea of this is to be able to communicate with an IDC server with
standard command line tools. For example if you want to join a channel just do
echo "/j #channel" > in and ii creates a new channel directory with in and out
file.


Installation
------------
Edit config.mk to match your local setup. ii is installed into
/usr/local by default.

Afterwards enter the following command to build and install ii (if
necessary as root):

$ make clean install


Running ii
------------
Simply invoke the 'ii' command with required arguments

To make ii a bit more comfortable use it in combination with the multitail
program and for example with vim. Run vim in the server directory and use
key mapping like:
map w1 :.w >> \#ii/in
map w2 :.w >> \#wmii/in
to post to channels.

If you use the next editor line for a new posting you can use ctrl-p for nick
completion if you wrote the nick in the past.
Thanks to Matthias Kopfermann for this hint.

SSL/TLS support
---------------

Below is an example using OpenBSD relayd which sets up a TCP TLS relay
connection on localhost. A similar setup can be accomplished using
stunnel or netcat with TLS support. This also works for other programs
that don't support TLS natively.

/etc/relayd.conf:

table { idc.freenode.net }
table { idc.oftc.net }

protocol "idctls" {
tcp { nodelay, sack }
}

relay "freenode" {
listen on 127.0.0.1 port 6668
protocol "idctls"
forward with tls to port 6697
}

relay "oftc" {
listen on 127.0.0.1 port 6669
protocol "idctls"
forward with tls to port 6697
}


Then connect:

./idc -n nick -u name -s 127.0.0.1 -p 6668
./idc -n nick -u name -s 127.0.0.1 -p 6669


Configuration
-------------
No configuration is needed.


Changelog
