You can test the connection to a TcLink by starting the TcLink with the debug argument ( tclink debug). Then you can telnet from any system to that tclink (e.g., telnet 10.1.1.1 7078). If there is a live connection, the linux tclink should display some information on the screen as a result of the telnet.
On linux, tclink communicates via the 7078 port. On Java, tclink communicates via port 7076 but doesn’t print anything.
If you are having trouble using YaST to configure the IP addresses of your NICs, you may use the following commands.
