Ubuntu installation package actually does not bring the OpenSSH server, so to telnet to the Ubuntu host using SSH, you need to first install the SSH server:
sudo apt-get install Openssh-server
After installation, start the SSH service:
Sudo/etc/init.d/ssh start
sudo service ssh start
Where the port defaults to 22.
Winscp+putty is commonly used in Windows as an SSH client. Since Ubuntu uses UTF-8 encoding by default, the encoding of the two tools is configured separately, otherwise the Chinese display is garbled.
WINSCP, set "Environment"-"File name UTF-8 encoding" to "on".
In Putty, "window---translation" in the "Received data assumed to is in which character set:" Select "UTF-8" in the drop-down list. After returning to the session interface, select "Default Settings" and save to note the configuration, which will be loaded automatically the next time you run it.
