What does mchat ?
Mchat is a very simple and small application I have written for
teaching multicast to my students.
Mchat sounds like for Multicast Chat. Mchat provides a way to communicate
between several users exchanging simple text messages as IRC'users do.
When an user sends a message to the other members of the group,
each member receives the same message, prompted by the string
[user@host]. Any member can participate at this forum, both
in transmit and reception.
How to install mchat ?
To build mchat, just type make.
To install mchat, just type make install.
How to use mchat ?
To start mchat in mode line, only type mc. It starts with a
default group address, a default port and a default ttl=16
limiting the scope in the site.
To start mchat in a xterm window, type mchat.
You can change theses parameters using the following syntaxe:
# mode line
$ mc -t ttl dest/port
# mode xterm
$ mchat -t ttl dest/port
Mchat can be also launched by sdr if its plugin is installed in ~/.sdr/plugins.
The name of this plugin is "sdr2.plugin.S42.text.udp.mchat" and its
content is:
media:text
proto:udp
tool:mchat
icon:text
fmt:mchat
{
fmtname:mchat
}
flags:-t $(TTL)
flags:$(ADDRESS)/$(PORT)
The script-shell mchat started by sdr launches mc in a xterm window.
