I do not know if I was misinformed, but it does not have the exected result.
I was told that in order for a developer to have read/write access to /var/www the user had to be added to the www-data group.
I have already successfully enabled the user to log in using ssh. When I log in as that user using ssh, I can change to /var/www, and I can read the only file there (index.html). However, I can not edit it.
I added the user to www-data using the following:
usermod -a -G www-data theuser
When I do so, I can see in the group file that the user name has been added to the end of the www-data record. But nothing else seems to have changed. The user still can not edit anything in /var/www.
What did I miss?
