HP ftp vs proftpd

[MikeL_4]

After installing proftpd on a server I cannot ftp to that server, but if I change back to using the origional ftp it works fine.

proftpd error:
421 Service not available, remote server has closed connection

root:[/root]:=>ftp mfl-hpux
Connected to mfl-hpux.
220 mfl-hpux FTP server (Version 1.1.214.4(PHNE_33412) Mon Sep 19 18:45:21 GMT 2005) ready.
Name (mfl-hpux:root):
331 Password required for root.
Password:

ftp> bye
221 Goodbye.
root:[/root]:=>ftp mfl-hpux
Connected to mfl-hpux.
421 Service not available, remote server has closed connection
ftp> bye

Any ideas as to why one works and the other doesn't ??

Hi Mike,

have you checked /etc/pam.d/ftp, and /etc/ftpusers file for authentication?

if not you can also read about how-to debug proftpd.

I don't know this software, but generally it's very unsafe to ftp with root account, because the password is transfered in plain text.

I can imagine to logon with root account is disabled by default. Did you try another user?

Thanks, the link provided information that showed the issue and I was able to resolve..

AS a extra question, do you have any information on setting up SSL Certificates using proftpd ??

Hi Mike,

Use below link for the SSL configuration on proftpd under "How to configure Proftpd for SSL/TLS authentication/encryption"

If you want a state of the art ftp then you need to install SSH

and use sftp. It's secure - why mess around with 3rd part sh!t?
Use sftp & sleep better at night.

My 2 cents,
Jeff

This time, I can only agree with Jeff!

Thanks, but our client does not want to use sftp, says it's not secure enough.
