In order to run a secure temporary chat server, boot from the Bootable CD, set the root password, configure networking and allow ssh inbound, add user IDs for the participants, and off you go. Here's a sample:
> passwd root New Password: don'tusethis Repeat New Password: don'tusethis > pump > ifconfig > service sshd start > adduser u1 > passwd u1 New Password: examplepassword1 Repeat New Password: examplepassword1 > adduser u2 > passwd u2 New Password: examplepassword2 Repeat New Password: examplepassword2 > adduser u3 > passwd u3 New Password: examplepassword3 Repeat New Password: examplepassword3 > adduser u4 > passwd u4 New Password: examplepassword4 Repeat New Password: examplepassword4
Please DO NOT use the passwords provided here - this will make your system very insecure indeed.
From each user's remote system, they can then participate by starting up two terminal windows. In one they run:
> sshsee
In the other they run:
> sshsay
The 'see' window provides a periodically updated (every 2 seconds) result of the last 20 lines of conversation while the 'say' window provides the ability to add to the discussion. User IDs, passwords, and the IP address will have to be provided to participants. If this syntax does not work, try ssh login and then, from each of two command windows type, respectively, see and say.
There is a combined 'see' and 'say' for people running X11. Just use:
> sshseesay
This should pop up a both a 'see' and a 'say' window on the screen, with the 'say' window below the 'see' window and smaller. Type into the 'say' window to operate. Type [ctrl]-C in each window to terminate it.
