[CLUE-Tech] groups

[Mike Staver]

Ok, so let me see if I have this correct - in /etc/passwd, is the second 
column of numbers the group id?  If so, I just need to create a group in 
/etc/group, assign it a number that's not already being used, and then 
I'm ok.  My only question remains then - how do I give ownership of a 
file or directory to a group and not an individual?  I have used the 
following command on a directory:

chgrp ftpguys /home/ftp_files

so, an ls -l shows:

drwxr-xr-x    2 staver   ftpguys         4096 Apr 30  2002 ftp_files

Then, in /etc/group I have:

ftpguys:x:512:cguest,chris,boz

Then, in /etc/passwd I have:

cguest:x:507:512::/home/files/./Castle_Productions:/etc/ftponly
chris:x:508:512::/home/files/./Castle_Productions:/etc/ftponly
boz:x:509:512::/home/files/./Castle_Productions:/etc/ftponly

Yet, when I ftp in as one of these accounts, I don't have read/write 
permissions in the directory I want.  Am I missing something?
