    Re: How to use talk command?

    I encountered the talk command when I was looking for a way to message people on my network... Is there another way to do this?
    I was looking for something that did popup windows, like when you leave a message on a locked screen...

    I've never used talk outside a lan so I cannot comment on how to do it. But let me point out that you can also chat with netcat or cryptcat. First install it:

    Code:
    sudo apt-get install cryptcat
    In the first machine use

    Code:
    cryptcat -nvlp <port_number> -k <password>
    and the in the second use

    Code:
    cryptcat -nv <ip_number> <port_number> -k <password>
    Works similarly to netcat. I think cryptcat is better for net chatting as it sends everything encrypted. While chatting I prefer that one sides starts his lines with the plus sign so they are easier to see.

    Note that there is also socat which can use openssl:
