BLACK BOX

Advanced Console Server
How it works
The Master box (BLACK BOX
®
Advanced Console Server) will perform two translation for
each packet. The destination IP address is translated in the PREROUTING stage. The source IP
address is translated in the POSTROUTING stage.
The command to start a telnet client session has not changed. As before, it looks like this:
telnet <clustering_ip> <master_port>
And it will have the same result as the command below issued from a local workstation:
telnet <slave_ip> <slave_port>
The command to start an ssh client session must have the following command line option:
-p <master_port>
The <master_port> will define at least the Slave box with which a connection is desired.
For example, you may use the following commands:
ssh -l <username1>:<server1> -p 7101 <master_ip>
ssh -l <username2>:<server2> -p 7101 <master_ip>
The above commands will respectively have the same result as the following commands
issued from a local workstation:
ssh -l <username1>:<server1> <slave1_ip>
ssh -l <username2>:<server2> <slave1_ip>
If the parameter <master_port> defines the local IP address assigned to the serial port, the
command can be simplified:
ssh -l <username1> -p 7101 <master_ip>
ssh -l <username2> -p 7102 <master_ip>
And it will have respectively the same result as the commands below issued from a local
workstation:
