The Secure Shell port (SSH)

It sets the Abilis CPX lower level port. It can only be an TCP port.

Value "NONE" isolates the SSH port.

This parameter is used for setting how the port has to behave if data compression is active.

The port connected to the X.25 network is defined NETWORK port; the one connected to the user equipment USER port.

The NETWORK port sends compressed data and expands the received ones; the USER port compresses the received data and sends the expanded ones.

The SSH port can be only USER.

The changes made on this parameter are immediately activated, without the need of initialisation commands.

If MCAU is set to NO, Abilis CPX transports, without any changes, the cause and diagnostic code of the CLEAR packets; it also uses the F0 cause code and the suitable diagnostic one for all the CLEAR packets internally generated.

If MCAU is set to YES, Abilis CPX forces the cause code of the CLEAR packet sent to the value 00 (DTE originated), either for the external CLEAR and the internal ones

The changes made on this parameter are immediately activated, without the need of initialisation commands.

Maximum length of COR packet size (in bytes).

It sets the local IP port used by the SSH port. The IP number assigned by default to the SSH process (according to recommendations) is 22.

This parameter has got only informative value and cannot be modified.

It activates and set the value of the "Keep-Alive" time-out.

The "Keep-Alive" procedure, by sending the homonymous packets, keeps on the TCP connection even if data are not exchanged. The parameter set the idle time interval (in seconds) which precedes the activation of such procedure.

If the parameter is set to NO, the procedure is not active.

If its value belongs to the interval [15-65535], the procedure will be activated only when the correspondent time-out will run-over.

It selects the directory where HOST and SERVER keys are stored.

This parameter must be a physical full path in DOS notation, i.e. starting with a drive letter in the range ['A'..'Z'] and ending with the backslash ('\') character. Accepted values are strings of up to 128 ASCII extended characters in the range [32..255]. Spaces are allowed and strings holding spaces must be written between quotation marks (E.g.: "C:\My dir\"). The case of the entered string is preserved.

This parameter set the prompt of the commands interpreter of the SSH Server port.

The local IP address, expressed in Dotted Decimal Notation and in square brackets (e.g. [xxx.xxx.xxx.xxx] ), always precedes the prompt defined by the user.

It is possible to use string from 0 up to 16 ASCII characters characters in the range [33..126], spaces are not allowed.

For deleting the SSH Server identifier this parameter has to be left without value: "S P PO:xxx PSER:", where "xxx" stands for the SSH port identifier.

It selects the autoconnection mode for the SSH Server.

The default value is "YES". In this way the SSH Server automatically generates a connection request, using information configured in parameters CDO: and UDO:, whenever it receives a login request from a Client SSH Server.

This parameter selects the idle time interval after which the connection is closed (in minutes).

It sets the SSH Server password, which is asked at the connection.

It is possible to use from 0 up to 16 ASCII characters in the range [33..126], spaces are not allowed. No differences between low and high case characters are made.

Once it is set the new password will be, encryptly, saved on disk through the command "SAVE CONF".

Every time the user wants to access the SSH Server, he will need to insert the password.

For deleting the password this parameter has to be left without value: "S P PO:xxx PWD:", where "xxx" is the SSH port identifier.

It sets the called address field of the SSH Server outgoing call. The default value, jointly with the parameter AC: set to "YES", allows to connect to the Control Port.

It sets the User data field [1] of the SSH Server outgoing call. The default value, jointly with the parameter AC: set to "YES", allows to connect to the Control Port.

This parameter selects the number of SSH Server processes predisposed on the SSH port.

The parameter configures the IP address of enabled source SSH Client system.

The allowed values are shown in the following table:

IP addresses of class D and E are not currently supported.

The value '*' means "any Ip address" and it is used to enable SSH requests received from any SSH Client.

The parameter configures a list of IP addresses of enabled SSH Client systems.

It must be set to the name of an IP or IR or RU or MR list. The referenced list must already be defined in the Elements Lists service.

The value '#' stands for "no list".

This parameter selects the SSH Server RSA key length (in bits).

This parameter selects the SSH Server RSA key regeneration time (in minutes).

This parameter selects the host RSA key length (in bits).

This parameter selects the maximum number of authentication attempts for a SSH Client.

This parameter selects the cryptography algorithms that are supported by the SSH Server.

It can be set to "ALL", i.e. all ciphers, or it can be a combination of the following available ciphers:

This parameter selects the authentication method that is supported by the SSH Server.

This parameter set the prompt of the commands interpreter of the SSH Client port.

The local IP address, expressed in Dotted Decimal Notation and in square brackets (e.g. [xxx.xxx.xxx.xxx] ), always precedes the prompt defined by the user.

It is possible to use string from 0 up to 16 ASCII characters characters in the range [33..126], spaces are not allowed.

For deleting the SSH Client identifier this parameter has to be left without value: "S P PO:xxx PCLI:", where "xxx" is the SSH port identifier.

It sets the called address field of the SSH Client incoming call.

It sets the User data field of the SSH Client incoming call.

This parameter selects the maximum number of SSH Clients processes predisposed on the SSH port.

This parameter selects the default cipher type of SSH Client.

It can be one of the following available ciphers:

If it is set to "AUTO" value, the SSH Client will try to select the cryptography algorithm automatically.

This parameter selects the maximum number of unsuccessful inputs of password for the SSH client.

This parameter selects the cryptography algorithms that are supported by the SSH Client.

It can be set to "ALL", i.e. all ciphers, or it can be a combination of the following available ciphers:

This parameter selects the authentication method that is supported by the SSH Client.

It shows the current state of the the SSH port.

It shows the number of channel on the SSH port. The maximum number of the available channels is given by the number of Server processes (configuration parameter ser:) summed to the number of Client ones (configuration parameter cli:).

It shows the type of the process active on the channel: the abbreviation "SERV" identifies the Server process, the one "CLNT" the Client process.

It shows the current state of the connection, towards the Connection Oriented Router.

It shows the current state of the connection, towards the TCP port.

It shows the IP local address used by the connection, whose state has not to be READY.

It shows the IP local port used by the connection, whose state has not to be READY.

It shows the IP remote address used by the connection, whose state has not to be READY.

It shows the IP remote port used by the connection, whose state has not to be READY.
