Introduction:

Do you know what’s SSH? Okay, here I’d like to bring some useful information about SSH. And if you’re looking for a reliable web hosting who can support SSH, this is the correct place you’ve arrived.

What’s SSH?

SSH is Secure Shell - A network protocol that allows data to be exchanged using a secure channel between two networked devices.

SSH was Used primarily on Linux and Unix based systems to access shell accounts.

SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notably passwords, in plaintext, leaving them open for interception. The encryption used by SSH provides confidentiality and integrity of data over an insecure network, such as the Internet.

SSH Features:

Secure Remote Logins: Suppose you have accounts on several computers on the Internet. Typically, you connect from a home PC to your ISP, and then use a telnet program to log into your accounts on other computers. Unfortunately, telnet transmits your username and password in plaintext over the Internet, where a malicious third party can intercept them.[3] Additionally, your entire telnet session is readable by a network snooper.
Secure File Transfer: Suppose you have accounts on two Internet computers, me@firstaccount.com and metoo@secondaccount.com, and you want to transfer a file from the first to the second account. The file contains trade secrets about your business, however, that must be kept from prying eyes. A traditional file-transfer program, such as ftp, rcp, or even email, doesn’t provide a secure solution. A third party can intercept and read the packets as they travel over the network. To get around this problem, you can encrypt the file on firstaccount.com with a program such as Pretty Good Privacy (PGP), transfer it via traditional means, and decrypt the file on secondaccount.com, but such a process is tedious and nontransparent to the user.Using SSH, the file can be transferred securely between machines with a single secure copy command. If the file were named myfile, the command executed on firstaccount.com might be:$ scp myfile metoo@secondaccount.com:When transmitted by scp, the file is automatically encrypted as it leaves firstaccount.com and decrypted as it arrives on secondaccount.com.
Access Control: Suppose you want to permit another person to use your computer account, but only for certain purposes. For example, while you’re out of town you’d like your secretary to read your email but not to do anything else in your account. With SSH, you can give your secretary access to your account without revealing or changing your password, and with only the ability to run the email program. No system-administrator privileges are required to set up this restricted access.
Port Forwarding: SSH can increase the security of other TCP/IP-based applications such as telnet, ftp, and the X Window System. A technique called port forwarding or tunneling reroutes a TCP/IP connection to pass through an SSH connection, transparently encrypting it end-to-end. Port forwarding can also pass such applications through network firewalls that otherwise prevent their use.

How to use SSH?

SSH is a protocol that can be used for many applications across many platforms including UNIX, Microsoft Windows, Apple Mac and Linux. Some of the applications below may require features that are only available or compatible with specific SSH clients or servers. For example, using the SSH protocol to implement a VPN is possible, but presently only with the OpenSSH server and client implementation.
