The Linux graphical X-window login offers additional Linux GUI tools for system management.
Tasks such as changing IP addresses and checking hardware are much easier within the
X-window GUI. However, if all iNEWS Servers have the GUI installed as part of the Linux
installation, it does take additional resources to run and requires additional hardware, such as
monitor, keyboard, and mouse. Some system managers might not want to run the GUI full-time so
as to reserve memory and other resources for the iNEWS Server processes.
While the impact of running the GUI is probably not terribly significant on modern hardware
with speedy processors and plenty of RAM, Avid does not test the software or system
performance with the GUI running. This editing alternative is not required or supported by Avid.
Before editing any system file, Avid recommen
ds you make a backup copy of the file.
Making a Backup File
When you want to make changes to a system file, begin by making a backup copy of the file, and
then edit the backup file. That way, if you make a mistake during the editing process, your
original file version is preserved.
To make a backup copy of a file:
t Use the copy command at the console in the following format:
cp <file pathname> <new pathname>
For instance, to copy the configuration file in the Site directory, type:
NRCS-A$ cp /site/config /site/config.backup
Viewing System Files
When viewing a system file, use the more command at the console.
The format is:
more <file pathname>
The more command allows you to view one page at a time, which is especially useful for really
long files. The cat command may also be used, particularly for smaller files.
To use the more command to view your copy of the configuration file:
t Type: NRCS-A$ more /site/config.test
