i connect to a linux box with scp (SSH2)
I have a problem changing group ownership. Specifically when viewing the properties of a file or directory, there are many missing group names missing. There are only admin, dialout, cdrom, floppy, audio, video and plugdev groups. All the others are missing.
If I view the properties of a file/directory that has another group, the group name is shown correctly.
When I try to change the group by typing in the missing group name, I get for example (the user I login with has full permission)
Command 'chgrp "www-data" "rss4j.jar"'
failed with return code 1 and error message
chgrp: changing group of `rss4j.jar': Operation not permitted.
When I try to change the group with a custom command, I get the same error
Although I'm interested only for froup memberships, the user names are missing too
Am I missing something?
