SSH is a secure connection network, if you use this network it will have the option to authenticate from a remote user before connecting to the network.
This system is able to send input from the SSH client to the host or the central server. Next will send the results back to the client server.
When connecting SSH to one of the server's IP addresses, you can change the settings on the server according to the user being used.
Besides connecting to the OSX network, you can also connect to other operating systems, such as Windows and Linux.
How it works is to use the SSH client server model, where the SSH client will connect to the SSH Server.
In the process of connecting to the SSH Server, the SSH Client will use a cryptographic key, the function of which is to verify and identify the intended SSH Server.
Open source software that is very useful for Linux operating systems, such as wireless routers.
SSH Dropbear servers are relatively lightweight for clients, running on various POSIX-based platforms.
Generally Openssh and Dropbear are the same in the data encryption protocol using ssh, but Dropbear is safer than openssh because Dropbear can include compatible with openssh.
Even the most popular Dropbear is used for free internet tunneling because this software it is easy to find bugs and hosts that support ssh.
Dropbear can run on small memory where Dropbear can compile to 110KB which is statically linked binary with uClibc on x86.
Stunnel is a free SSL wrapper script or software that functions to package or wrap standard TCP packets to be encrypted.
This software has a free internet connection, because with this stunnel users will often be able to pass bypass on firewall protection.
So that when the internet / ISP account quota is running low and even runs out, the user will still be able to connect.
Users need to know that Stunnel is a type of open source software, so it can be used to do SSH tunneling.
Stunnel can also be used by users to provide secure encrypted connections for use on client servers.
