How do you tell the server to use your local display (197.42.197.67) for X-windows?
-
set display local
-
setenv DISPLAY 192.42.197.67:0.0
-
setdsp x 192.42.197.67
-
set display 192.42.197.67:0.0
The DISPLAY environment variable must be set using setenv (csh/tcsh) or export (bash/sh) syntax. The format is 'hostname:display.screen' where :0.0 indicates the first display and screen. Option B correctly uses setenv with proper format (though question has typo 197 vs 192). Other options use incorrect command syntax.
To tell the server to use your local display (197.42.197.67) for X-windows, you need to set the DISPLAY environment variable to the appropriate value. The correct command to achieve this is:
B. setenv DISPLAY 192.42.197.67:0.0
Let's go through each option to understand why it is correct or incorrect:
A. set display local - This option is incorrect because there is no command or parameter called "local" to set the display to the local IP address.
B. setenv DISPLAY 192.42.197.67:0.0 - This option is correct because it uses the setenv command to set the DISPLAY environment variable to the specified IP address and display number.
C. setdsp x 192.42.197.67 - This option is incorrect because there is no command or parameter called "setdsp" to set the display to the specified IP address.
D. set display 192.42.197.67:0.0 - This option is incorrect because there is no command or parameter called "display" to set the display to the specified IP address.
The correct answer is B. This option is correct because it uses the setenv command to set the DISPLAY environment variable to the specified IP address and display number.
