Administration > SSH
SSH (Secure Shell) is a program to log into another computer over a network to execute commands in a
remote machine and to move files from one machine to another. It provides strong authentication and secure
communications over insecure channels. It is intended as a replacement for rlogin, rsh, and rcp.
SSH is a command line interface. Access via SSH is encrypted.
For access via SSH
,
you need SSH Client, which most Linux systems already include. For MS Windows, the
program
PuTTY
is very common as a SSH client.
Status
This screen opens with
Status
as the only prompt. Once it is checked and saved, SSH is enabled and the
other options display.
SSH requires name resolution for the access protocol, otherwise a time-out occurs with the SSH
registration. This time-out takes about one minute. During this time it seems as if the connection is frozen,
or can’t be established. After that the connection returns to normal without any further delay.
Allowed Networks
The networks that are to be allowed to access the MultiAccess using SSH must be enabled.
The default setting
Any
in
Allowed Networks
means everyone is allowed to access the SSH service.
Networks are be defined in
Networks & Services > Networks
menu
.
Caution:
The default setting (
Any
) allows everyone to access the SSH service. For security reasons we
recommend that you restrict the access to the SSH service. You should delete access from all other
networks!
