Hi,
I've tried a lot to create an FTP user (in debian) in my server (with SSH access), i have the root permission on server.
I've followed those instruction :
# apt-get install pure-ftpd-common pure-ftpd
# groupadd ftpgroup
# useradd -g ftpgroup -d /dev/null -s /etc ftpuser
# pure-pw useradd remo -u ftpuser -g ftpgroup -d /home/pubftp/remo -N 10
# pure-pw mkdb
but when i try to connect with an FTP client, a problem occur (can't connect to the server).

Can anyone help me to solve this problem (i've lost 4 hours to do this, and i've followed many instructions in my search but no results).
Thank you

You could try to edit /etc/default/pure-ftpd-common .
In this file look for STANDALONE_OR_INETD=inetd and change it to STANDALONE_OR_INETD=standalone

I hope this helps. It did for me.

Sorry but i didn't understand what you asking me to do for getting solution to my problem.
The problem i have, that when i try to connect by ftp server using for example (filezilla or smartftp) i have those message:
Status: Connecting to My_Ip:21...
Status: Connection established, waiting for welcome message...
Error: Could not connect to server
Also when i try this command to test the server in SSH mode
/usr/sbin/pure-ftpd -S 127.0.0.1,21 -c 30 -C 1 -l puredb:/etc/pureftpd.pdb -x -E -j -R
I have this message:
Unable to start a standalone server: Address already in use

I've also changed proftpd.conf with "ServerType standalone" the same messages appears.
When i'm trying this command "dpkg -l | grep ftp"

ii dpkg-ftp 1.6.10 Ftp method for dselect.
ii ftp 0.17-12 The FTP client.
ii ncftp2 2.4.3-14 A user-friendly and well-featured FTP client
rc proftpd-common 1.2.10-15sarge Versatile, virtual-hosting FTP daemon
rc proftpd-mysql 1.2.10-15sarge Versatile, virtual-hosting FTP daemon (with
ii pure-ftpd 1.0.19-4 Pure-FTPd FTP server
ii pure-ftpd-comm 1.0.19-4 Pure-FTPd FTP server (Common Files)

Did i have more than one configuration for FTP connection.
I don't know what to do to resolve this problem.
Can i remove all installation of FTP configurations in my server and can you give all the exacts steps to configure FTP.
Thank you for your precious help.

Am I right that you try to use pro-ftpd and pure-ftpd at the same time? Because than I can imagine that problems occure.

So do you have any idea to resolve this problem. Thank you

Well... you cannot run two different ftp servers on port 21. So you either you have to set a different port for one server or you will have to run only one ftp server. I suggest that you pick one server and uninstall the other.
I have limmited experience with ftp-servers but 'till now I prefer pure-ftpd.
