Thanks for your help.
As soon as I connect (after “^Ec;”), when I press enter once the remote system CLI (Command Line Interface) of the switch will send a “login:” prompt. However, it shows it twice like if I had pressed enter twice. So I can’t login because the same happens to the passord…
I am trying to “buy” a dynamic DNS to give public access to my lab, so anyone can come in, check it, change it, try it, etc. By the way, I forgot to mention that I am using getty as the Telnet client. So the full lab environment is:
An Intel IBM-PC;
CentOS 4.2 (Linux kernel 2.6);
The standard IBM PC serial pors (COM1, COM2);
The config I published in my first e-mail;
Getty as the Telnet client;
Logging in as “root”;
An Alcatel switch and a 3Com ADSL modem as console to be remotely accessed;
Any help will be appreciated!
It sounds like your TTY may be set for "local echo"... if
have NOTHING connected to the port, and use telnet to connect,
and then type, you see the characters, correct? The 'double
characters' come from your terminal displaying what you type,
and then the character is returned from the remote device...
In normal operation, you would NOT see what you typed...it
would only be sent to the 'far end', and you would rely on the
far device to return your keystrokes...
To test this theory, conect it to something that wants a password
to log in...type the username as norlam (you will see the double
characters, but the far end will only see one of each)...when you
type the password, one character will be "clear text", and the other
will be an asterisk (*, if the system masks the input), or you may
only see the single clear-text password if the system doesn't show
any masking characters.
Take a look at your termcap?
