The "talk" command allows you to talk to other users on the same system, which is useful if you're both SSH'd in from somewhere. Using it is very simple; to talk to someone the command is just
talk <username> <tty>
Of course, you can talk to users on another system as well:
talk <username>@<hostname> <tty>
In either case, the tty is optional. It is used if you wish to talk to a local user who is logged in more than once to indicate the appropriate terminal name. "tty" is of the form 'ttyXX', or 'pts/X'.
- First, install the inetutils package, which contains talk and talkd. These also rely on xinetd, so install that as well. You might also need the screen command; it's in the screen package.
pacman -S inetutils xinetd screen
- Configure the xinetd service entry by editing
/etc/xinetd.d/talkand setting "disable = no".
- If you are using tcp_wrappers or something similar, add an entry to
- Now start xinetd:
systemctl start xinetd.service
- If you're on the local system, you might need to start a screen session to make yourself show up on the "w" and "who" commands -- you need to show up there or talk won't work.
- Allow write access in your terminal if needed:
Talk should work now.
Using systemd directly
First, create the following two files in

Then activate the talkd daemon:
$ sudo systemctl start talkd
Now, the Lennart is strong in you!
