Hi,

I wanna chat with my friend via text messages.
The first thing I thought was IRC, but I don't like the idead of connect with a big server, to private chat.
Is there a chat system with direct connection and a self hosted files?
How this is instant messaging, I don't need a 24h server maintaining my account up, i'll just need to be connected while i'm chatting.

Since i can do this, can i also share video and others files with him?

You could try the Mumble/Murmur combo. It's similar to Teamspeak or Raidcall, where you can can have chat rooms with audio and text. Mumble is the client part, and Murmur is the server part. You can connect to public servers, which is what I think you don't want. Or you can install Murmur on your machine and use yourself as a server that your friends can connect to.
Limitations: Can't send files (I don't think), and you must be connected to the server to receive messages.
But, it's open source... so that's nice :P

henriqueleng,

There is talkd or ytalk.
You all ssh in to the same system and run talk.

For file sharing you can use sttp.

talkd predates the internet ...

henriqueleng,

You can use w or who to see who is logged in.
Test that on you own system.

There are ssh clients for Windows (PuTTY) Embedded Systems, (dropbear).
I've not used BSD but SSH is a key remote system admin tool, it will be there.

Another questions.

If "Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers." (wikipedia) How it work for example with IRC servers?
I imagine something like:
MYCOMPUTER ----SSH--> IRC SERVER ----SSH---> USERSCOMPUTER

Can I implement under this connection tunnel a chat protocol like SIP, too make thing easier?

You can use tox.

There are a lot of clients for tox.
- uTox is a lightweight client for windows/linux/osx/android. (possibly supports audio calls)
- Antox is a more popular android client
- toxic is a nice CLI client for linux (supports audio calls, tested and works)
- venom is a GUI client for linux (doesn't seem to support audio calls)

They are available in gentoo-overlay-tox: https://github.com/fr0stycl34r/gentoo-overlay-tox.

It's pretty straightforward and requires no registration. DHT so it's peer-to-peer (UDP hole punching so mostly direct communication). It also uses good cryptography like ed25519 and AES so it should be secure for now.

You can always setup your own irc server. Inspircd is easy enough to setup. There's also unrealircd, both in portage.

Then your friends can connect to your ip, or you could use some dynamic domain name service such as dyndns or no-ip so that they can connect using a domain name.

After some fails with SSH, i tried tox and really liked it. Awesome.
I'm using toxic the (cli client) wich I installed from the overlay, and i tried a audio call with other client (utox) on windows, everything worked.
