The network administor must have physical access to the device to establish a console connection whereas TELNET access can be established form a remote location. However telnet access depend upon a router with network access's, whereas a console connection can be used to access the router regardless of the router's configuration.
Telnet use port number 23,and connected to TCP
Telnet operates over TCP Port 23.
Because the telnet session is in clear text and programs can capture the passwords to log in to telnet sessions.
Port 23 is the traditional port used for Telnet. Telnet is basically a protocol to allow a user to connect to another computer or server in order to view information or log in. When this port is open, it is often an indication that a malicious piece of software has planted a backdoor in your computer to allow other users to access it without your permission.
Telnet is a protocol for transferring plain text over TCP .
because telnet sucks!!
In order to be able to telnet to a computer, it has to be running a telnet daemon or service. Windows XP does not run such a service by default. It can be activated (in the Professional version at least) in the Services console.
A user can access Cisco IOS through the console port using a direct physical connection via a console cable, which allows for initial device configuration. Alternatively, users can access IOS remotely via Telnet or SSH, provided that the device is configured for remote management and the appropriate network access is available.
hehehehe no comment!!!!!!!!!!!!!!!i am looking for an answer......
Telnet offers no encryption, everything sent is in clear text including passwords.
The correct answer is VTY.
Most inexpensive switches do not have the capability to log into them because they don't need to be managed or configured. For managed switches that do, either the use of Telnet protocol or a console port will allow access to the switch.
The entries specify four Telnet lines for remote access. Access will be permitted for Telnet using "c13c0" as the password
TELNET commands are primarily used to control the TELNET client and manage remote connections. Basic commands include open to connect to a remote host, close to disconnect, status to display connection information, and help to access a list of available commands. Users can also use control characters like Ctrl+] to access the TELNET command prompt for further commands. Additionally, commands such as set and unset allow users to configure various options for their TELNET session.
check that the login prompt on your console has changed, and use the "show session" command
If you connect to the router via the console port then you are physically making a connection with a physical cable to the router. This implies you have to be close to the router itself. Using telnet allows you to connect to the router from anywhere in the network, and doesn't require a physical cable connection.
Yes, but beware. Simply starting the telnet service on the PC will allow remote access, but telnet in known to be insecure. Also, additional configuration may be required if the PC being accessed remotely is not internet-facing, if in fact you are trying to access the remote PC over the web.
