SSH : Secure Shell
Using SSH [Secured SHell] is a very good mechanism to work on a remote system with full secured communication between client and server as the communicate is under SSL and no one sitting over the wire can read the encrypted data being transferred. SSH came up as a replacement to the old unsecured protocols like ftp,telnet. What all makes difference : - Security OpenSSH supports 3DES, Blowfish, AES and arcfour as encryption algorithms. These are patent free.Encryption is started before authentication, and no passwords or other information is transmitted in the clear. Encryption is also used to protect against spoofed packets. - Compression Requests compression of all data (including stdin, stdout, stderr, and data for forwarded X11 and TCP connections).The compression algorithm is the same used by gzipCompression is desirable on modem lines and other slow connections, but will only slow down things on fast networks. - Key based authentication [RSA / DSA] Strong authentication protects...
