Remote access
SSH remote access port Default: 22 (factory setting)
Firewall rules for SSH
remote access
You can define an alterative port. However, if you have defined an
alternative port, then the external remote station conducting the remote
access must specify the port number defined here in front of the IP address
when specifying the address.
Note
Additionally to the new selected port, the standard port 22 for SSH remote
access keeps open.
Example:
If this TAINY xMOD can be accessed from the external network using the
address 192.144.112.5, and if port 22222 has been defined for the remote
access, then this port number must be specified in the SSH client (e.g.
PUTTY) at the external remote station:
SSH -p 22222 192.144.112.5
Example for console:
New Adds a new firewall rule for SSH remote access that you can
then fill out.
Delete Removes a firewall rule for SSH remote access that has been
created.
From IP
(External)
Specify here the address(es) of the computer(s) for which
remote access is allowed. You have the following options:
IP address or address range: 0.0.0.0/0 means all addresses.
To specify a range, use the CIDR notation - see Chapter 11.
Action Define how access to the specified SSH port will be handled:
Accept means that the data packets can go through.
Reject means that the data packets are rejected, and the
sender receives a message about the rejection.
Drop means that the data packets are not allowed through.
They are discarded without the sender receiving any
information about where they went.
Log For each individual firewall rule you can define whether the
event should be logged when the rule takes effect - set Log to
Yes,
or not - set Log to No (factory setting).
The log is kept in the firewall log, see Chapter 6.4.
