The combination of an escape character and a dot (.) works as an escape sequence. This escape
sequence is typically used to quickly terminate an SSH connection when the server reboots or
malfunctions.
For the escape sequence to take effect, you must enter it at the very beginning of a line. If you have
entered other characters or performed operations in a line, enter the escape sequence in the next
line. As a best practice, use the default escape character (~). Do not use any character in SSH
usernames as the escape character.
Examples
# Use the 192-bit Suite B algorithms to establish a connection to Stelnet server 2000::1. Specify the
client's PKI domain and the server's PKI domain as clientpkidomain and serverpkidomain,
respectively.
