FTP and Telnet are similar in that they are defined as OSI layer 7 (application) protocols.
They are different in that they use different ports for sending and receiving messages and are used for different purposes. FTP is used to sending and receiving files across a network. Telnet is used to send commands remotely to another network device.
Both can be used to control a computer remotely through commands, but Secure Shell (SSH) is more secure than the older Telnet protocol.

Both telnet and rlogin are used to remotely log into another server and control it remotely. They do the same thing, but are actually different protocols.
Telnet requires the user to specify their username and password to log in.
Rlogin does not require additional authentication if the account name is the same between systems.
* ping only check connectivity, whereas telnet is remote access * ping does not need password while telnet does * ping is lay2-3 and telnet is lay7
Telnet is unencrypted, while SSH is encrypted, and thus more secure.
Both are used to connect the remotely situated computers.

SSH is more secure than Telnet.
ssh
SSH
Pinging a server just checks that Particular system is present on the network. Telnet or SSH are application to login the server from remote and use the services provided by the server. In TELNET DATA is not encrypted so it's easy to hack. In SSH DATA is encrypted so it's safe.
Telnet is non secure, travel data in open form you can easily theft/capture data, ssh is secure transmission of data over network, telnet is little bit faster than SSH, because it is not encrypting data, SSh is little slower than telnet because encrypt data when transmitting over network
rsh and ssh are similar in that they can execute commands on remote systems. The main difference between the two (besides the actual TCP ports) is that rsh traffic is not encrypted and therefore a security risk; ssh traffic is encrypted. The other main difference is that ssh is a secure replacement for telnet, whereas rsh can log into a remote system using the rlogin protocol, which is similar but not the same as telnet.
Use of SSH or VTY ACLs.
You don't. Use telnet, rlogin or ssh.
Putty uses port 22, the same as telnet and ssh.
*encryption
It will require you to SSH to the router rather than telnet. You will have to use a program like Putty or some other SSH client.
The command is bad configurate.
