My FTP Server is being attacked

[Laurijan]

Hi!

Need some advice from you tech-gurus!

I got my no-ip client running , besides that a program called Home FTP Server which is having no SFTP or SCP mode just FTP mode.
I gave a friend an user name and password so that he can access my shared folder.
After I activated the server and after he was connected for about 24 hours I saw that someone is trying to logging with the user name administrator and varios passwords - mainly names. I had to stop the server.
It is normal that Crackers/Hackers try to gain access?
Who knows how an outsider (Cracker) which a newer gave me FTP servers adress can attack me like that and are there any better FTP Server programs around preventing that from happening again?

Yes, its called password protection. If you expose your server to the internet via FTP... then you've exposed your server to the internet. LOL.

Just put on a decent password, or create a "secret port number ofr your FTP" and you are done.

i think what the original poster means is that there are repeated attempts to login on his ftp server via port 21 .. yes that's normal. i like to call it internet background noise :)

move ftp to another port and use proper passwords
