LinuxQuestions.org - FTP Permissions

First off lets install a FTP-server on your linux machine
go to non-grapichal mode ( textmode) login.

#download proftpd

command:

Code:

wget ftp://ftp.proftpd.org/distrib/source...1.2.10.tar.bz2

this will store proftpd in the direcotry where you executed this command

#installing/configureing proftpd
in the direcotry where you download proftpd

Code:

tar -xzvf proftpd-1.2.10.tar.bz2

cd proftpd-1.2.10 ( or the mapname of proftpd)

make

make install

#now proftpd is installed you have to configure the config file (proftpd.conf) that is located at /usr/local/etc/:

Code:

cd /usr/local/etc/

vi proftpd.conf

edit the following

Code:

# A basic anonymous configuration, no upload directories.  If you do not

# want anonymous users, simply delete this entire <Anonymous> section.

<Anonymous ~ftp>

  User                                ftp

  Group                                ftp



  # We want clients to be able to login with "anonymous" as well as "ftp"

  UserAlias                        anonymous ftp



  # Limit the maximum number of anonymous logins

  MaxClients                        10



  # We want 'welcome.msg' displayed at login, and '.message' displayed

  # in each newly chdired directory.

  DisplayLogin                        welcome.msg

  DisplayFirstChdir                .message



  # Limit WRITE everywhere in the anonymous chroot

  <Limit WRITE>

    DenyAll

  </Limit>

</Anonymous>

change <Anonymous ~ftp> into <Anonymous /your/direcorty/you/want/to/share> for example <Anonymous /home>

hit esc
shift + :
w
q

#now for the finishing touch

#give right to the map for testing ( nog save chmod)

Code:

chmod 777 path_of_the_map_you_gave_above

for example

chmod 777 /home

create 2 users with a group ( if then don't exist )

Code:

groupadd ftp

groupadd nogroup



useradd -g ftp ftp

useradd -g nogroup nobody

now you can start proftpd

Code:

cd /usr/local/sbin/

./proftpd -c /usr/local/etc/proftpd.conf

P.S.
all above works local. if you want some friends to access your ftp sever from outside your local lan, you have to edit IPTABLES if your running those, forward a port.
http://www.portforward.com/ here is some info about your router/modem.
you should forward 20 21 to the IP that your linux machine is running
