Permission problems - http is 0775, (root:http), I am in http -- still can't write??

[David C. Rankin]

Guys,

I have run into a permission problem I can't understand. I need write access
to the webserver on my laptop (that's where the developement happens). I have
always just made myself a member of the webserver group and give the group
write access to the document root (some applications require it). Today,
setting up the webserver, I did the same thing only to be met with a
permission denied message when I attempted a copy -- Huh?

Here are the details:

16:59 alchemy:/srv/http> l
total 8
drwxrwxr-x 2 root http 4096 2009-10-31 22:53 .
drwxr-xr-x 4 root root 4096 2009-10-31 22:53 ..
16:59 alchemy:/srv/http> grep http /etc/group
http::33:david
16:59 alchemy:/srv/http> touch testfile
touch: cannot touch `testfile': Permission denied

This is in konsole in kde4. I can't understand why the touch failed (I could
just be confused at the moment as well). I am a member of the http group
(added with gpasswd -a david http, not just edited like usual), the http group
has write permission to the http directory. But, when I try to write to the
http directory --> I get the error.

Can anyone see the error in my logic? (diplomatically, of course) What's the
trick?

Did you log out and then log back in for the group changes to take effect?

And what is the output of:
$ groups
?

Don't know if "gpasswd -a" is failing, I use:
# usermod -a -G groupname username

Another possibility is use newgrp $groupname if you don't want to log out,
it works for one terminal session.

It's there:

06:44 alchemy:~> groups
... lp wheel uucp http ...

It got to the point I just had to chown -R me:http /srv/http, I had to get the
webserver up. I don't know what the issue was, but even with group write
permissions properly set, I couldn't.

sheepishly -- Uh... Log out?  I think we have an answer. Why log out? I
changed group permission hundreds of times without having to log out. What's
the catch here?

Two different things:

- Changing group permissions, takes immediate effect.
- Changing group membership, requires logout/login.
