I have installed Apache and Proftp. I just started with them, but I want to make this quetions.
My apache server address is 192.168.1.5 and there is index.html-page in /var/www/html/rogk. So if I put the Firefox search line "192.168.1.5/rogk" the index.html-page open ofcourse.
The question is, how do I have to configure the "/etc/proftpd.conf", that when "rogk" logs in ftp, the opening folder is /var/www/html/rogk? I think that's how the webservers work, or is it?
I hope this wasn't a stupid question. Because I'm newbie and finnish is my main language, the man pages are little bit difficult to me,but I'm learning more all the time.

Most ftp clients have options to set the folder when you login. If your's does not then you can set that directory up as the user's home directory so long as it isn't used for anything else.

With proftpd, the user rogk home has to be /var/www/html/rogk (edit it in /etc/passwd). Then in /etc/proftpd.conf uncomment the line that says:

DefaultRoot ~

Then restart proftpd with proftpd restart, and you should be able to log in using rogk and it will chroot into the directory.

Thank you very much scuffell. That's the thing I meant.
