XWN740: Remote Access Lab #8
Question #1: Describe what happened. Why do you think this happened?
Answer: It returned a error message (as below). I think it's because there is a security rule that blocks incoming connection to default display.
[joker@localhost ~]$ xterm -display 142.204.141.146:0
xterm Xt error: Can't open display: 142.204.141.146:0
Question #2: Describe what happened.
Does this work when issuing the above command to run the
xterm application in server2 (i.e. the other way around)?
Answer: Yes it works on both servers.
Question #3: Try to provide a useful example how using this remote access method
would be useful for yourself in the future...
Answer: One of the useful way to use remote access is for running application in thin client. Since the application running on the target client will use the resources from source server, the target client dose not require to install any heavy packages, libarary to the application.
Question #4: What happened?
Answer: It returned an error message says the server is already running.
Question #5: What happened? Did you notice any difference between the -query method used?
Question #6: What happened? Which server is this xeyes application running from?
If you are not certain, create some test files in each server's home
directory, and issue the same command, but with the xterm application
instead of the xeyes application....
Question #7: Provide your own example how you would think this method of ssh
using tunneling would be useful for you in the future....
