HOWTO : Create a FTP server with user access (proftpd)

[dannyboy79]

I have read through all the posts here, read some 3rd party sites, and formatted my ubuntu box twice to try to get SSL/TLS secure ftp working.

My ftp works fine without encryption, however with encryption I get these errors.

WinSock 2.0 -- OpenSSL 0.9.8b 04 May 2006
[R] Connecting to 192.168.1.102 -> IP=192.168.1.102 PORT=21
[R] Connected to 192.168.1.102
[R] 220 ProFTPD 1.3.0 Server (Restricted-Access) [::ffff:192.168.1.102]
[R] AUTH TLS
[R] 234 AUTH TLS successful
[R] Connected. Negotiating TLSv1 session..
[R] error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
[R] Failed TLSv1 negotiation, disconnected
[R] Connection failed (Connection closed by client)
[R] Delaying for 120 seconds before reconnect attempt #1

Not quite sure...I have noticed other uses have had this similar problem, and any help would be much appreciated. Thank you in advance.

if you notice the handshake is attempting sslv3 and your server is using TLSv1, I am guessing the client you're using isn't using the correct encryption handshake protocol BUT with that said, I couldn't get TLS to work either. Kind of sucks if you ask me. Why don't you just tunnel in with SSH, that way all your ftp stuff will be encrypted within the SSH tunnel. I only have 1 port open, and that's for ssh and even that has Public/Private Key pair for authentification, so it's very secure. I then tunnel my x11vnc, my ftp, my mythweb all thru that tunnel.

I'm having trouble adding users.

I understand that multiple people can use the original user name, but I want some users to have a different home directory.

Can someone please explain how to successfully add users and be able to connect through smartftp

Thanks

[frodon]

You should find some examples in this thread, some users have posted configurations with several users and different home directory.

Hi
I have created proftp server on RHES, and it works fine, thanks to this post but I have some complaints when users try to log in. They say it is very slow when u try to log in and also when u browse the folders, some say it took them 2 min to log in. Download speed is good. Here is my profto conf file

I have successfully installed proftpd and run it as root. It works fine when I connect to it from inside or outside my local network.
I want to change the permissions so that the server runs as non root. However when I run it, I get the following error.

anoopk@app1:~$ sudo -u ftpuser service proftpd start

I have attached my conf file for the configuration details.

I have also tried adding the ip to the iptables
sudo iptables -A INPUT -p tcp -m tcp --dport 75 -j ACCEPT


I have searched on google and havent found anything to point me in the right direction, not sure if I missed anything in the forums either.
Any help will be greatly appreciated.
Thanks in advance,

I want to change the permissions so that the server runs as non root.

Why such a need ? It makes your computer more secure to require root rights to run or modify services

thx all for your help

[frodon]

The guide is for a standalone server no support is provided for the inetd mode. The line "ServerType inetd" shows that you are using the inetd mode.

[r0ot5]

I try using the standalone also & still giving me an error!

[frodon]

Then please give the error message, i can't guess what the problem is without error log.
