ssh and telnet

In networking world lot of people use ssh and telnet but they don't have more idea
in this protocol.actually one of my friend also ask me some question related with these things.Ok now you can follow this blog and get some idea.



SSH - secure shell(normally it use port 22)

SSH is network related protocol but it work in application layer which use SSL.SSL(443) make trusted relation ship.And also SSH Basically it is secured. It is most often used by network administrators as a remote login / remote control way to manage their business server.


#######for your knowledge--- SSL is most often used for transmitting credit card, tax, banking, or personal information to a business server.##########


Telnet - port 23-Application layer


Telnet is normal way u can connect to the server and work.Telnet send the data's in Ascii format and its not a secure shell.so we must't use telnet and ftp becoz hackers
can easy to identify our data.
