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'.

## Setup

### Using xinetd

1.  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` 
2.  Configure the xinetd service entry by editing `/etc/xinetd.d/talk` and setting "disable = no".
3.  If you are using tcp_wrappers or something similar, add an entry to `/etc/hosts.allow`: `talkd: 127.0.0.1` 
4.  Now start xinetd: `# systemctl start xinetd.service` 
5.  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.
6.  Allow write access in your terminal if needed: `$ mesg y` 

Talk should work now.

### Using systemd directly

Starting from inetutils 1.9.1.341-2, talk.service and talk.socket files are provided. Just upgrade and then activate the talk daemon:

 `# systemctl start talk.socket`  `# systemctl start talk.service`
