I recommend FileZilla FTP Server. Its free. You can find it by Googling for FileZilla FTP Server.

Serv-U FTP Server is a commercial but affordable FTP Server. Have used for years with consistently good results. My clients and I use it just about every day.

In FileZilla, you can ban IPs after a set number of failed login attempts.
This is the case with most FTP servers.

There are no security vulnerabilities in FileZilla that I'm aware of.
Your security is only as good as the password you choose. ;)

I am not aware of any successful brute force attacks with Serv-U FTP Server. IP banning is an available function of this software too.

....For example...
the user1 login with password normally
then uploads script1.asp
that when browsing it from any browser will delete or destroy some files at my webserver !

FTP servers won't do this. Its up to the server's scripting language to stop this sort of script from running. All FTP does is allow you to upload and manage files on the server.

The scripting language will have a configuration to stop this. For example php has base_dir which you can set in the php.ini. safe_mode also helps stop users running malicious functions but it doesn't stop everything.

Maybe you didn't understand me...

I have a server...

Users are a type of clients have their own webpages and they have knowledge of ftp/web servers.

I want to stop using other directories throught Map Server (fso commands) etc... at my server i give php / asp / html - and DSN - MYSQL (in different directories) - the client select the language that he want to work own site...

sorry for bad english :-(

I'm afraid I don't understand you, no.

FTP servers allow the uploading of files to specific directories only. They don't stop filetypes being uploaded or bad scripts being uploaded.

Thats about all I can say to be honest unless you can explain better.

Like I said in a previous post, it is down to the configuration of the scripting language to prevent this by (in php) using something like base_dir.

Having never used ASP I can't advise on that one but in PHP you can start by using base_dir in the php.ini. You will either need a seperate installation of php for each user or you can use the switch command in the abyss config (which I have no idea how to do but it will be something like 'php-cgi.exe -switch base_dir_name' or similar). Turning on safe_mode in the php.ini will prevent the users using commands like system() and shell_exec(), which can be dangerous to the system.

The solution is to run Abyss Web Server in a user account which has no permission to see the directories in your system that you want to hide. This is doable using the Windows Explorer file permission dialogs.

@aprelium:

i don't think that is a suitable solution...
because:

webmaster that have folder webpage1 could see the other webmaster's folder webpage2 too and will have the ability to use server commands with asp code to delete files at webpage2...

Giving InetPub to Internet Public gives to all users access to each other folders

I already have to other directories administrator/password authenication only and uncecked Internet Public....

Sorry i have Greek Windows xp pro so.. i don;t remember exactly the en windows xp pro..

cyberd,

We now better understand your requirements. Having such a setup is not yet possible and will probably be provided as a new feature in the next major release.

Right now, all the web sites files have to be readable by the same user account which is used to run Abyss Web Server.

Still, we have developed a small tool to limit the execution of a CGI application/interpreter using Windows permissions. This may be a solution for you. Please contact us for more information.
