The user needs an account and password and responds appropriately when ftp or telnet asks for the credentials.
Telnet is similar to HTTP and FTP in that all three use the TCP protocol for connection-oriented
tcp
FTP is a File Transfer Protocol (a method of transferring files from one location to another.... Telnet would be more of an emulation/connectivity protocol where you can connect to another system and Signon / natigate through the other systems menu option / type commands etc.... eg. you could use Telnet as 5250 emulation and sign on to the iseries (AS/400) once, connected you can do whatever the host system/user security permits you cannot do this in ftp
telnet,FTP,e-mail etc
Students and professors will be able to Telnet to the server but unable to FTP files to and from the server.
Might be that remote server connectivity has been lost ..or pls check your ip or login credentials
Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. Through Telnet, an administrator or another user can access someone else's computer remotely. On the Web, HTTP and FTP protocols allow you to request specific files from remote computers, but not to actually be logged on as a user of that computer. With Telnet, you log on as a regular user with whatever privileges you may have been granted to the specific application and data on that computer. A Telnet command request looks like this (the computer name is made-up):telnet the.libraryat.whatis.edu The result of this request would be an invitation to log on with a userid and a prompt for a password. If accepted, you would be logged on like any user who used this computer every day. Telnet is most likely to be used by program developers and anyone who has a need to use specific applications or data located at a particular host computer.
FTP and Telnet are considered OSI layer 7 protocols. If you are blocking the service, then layer 3 or 4 (network or transport) is responsible.
Telnet- is an application layer program that enables a user to remotely login and use resources of a remote computer.
If you want better security, use secure shell (ssh) instead of telnet. Actually, don't use telnet at all if possible, as it transmits all information in plain text.
Telnet is an application layer protocol (Layer 7). Its functionality is similar to any of the layer 7 protocols, including DHCP, DNS, FTP, etc.
Using FTP, TELNET, SNMP, SMTP etc we can share resources in computer networking.
