In Windows, like. Serv-U ftp, it can monitor the server who is upload, download, what file is being upload or download , etc

how about in proftp, any tool that can monitor the proftp activiates ?

Take a look at pure-ftpd (www.pureftpd.org) very nice very configurable and many options.

Hope that helps.

I'm talking on proftp server , not pureftp server

The reason I posted that link was because I don't think you can do what you are wanting to do with proftpd, not that proftpd isn't a great FTP server. I use it on a few of my servers but I also sometimes need more flexibility which proftp doesn't have. pure-ftp is a secure and stable alternative which does all that you are wanting and more. maybe an alternative, maybe not. If not, sorry I told ya. Good thing about linux is you have many programs and options to choose from, its up to you if you choose not to use them.

However, if you do find some tools that do what you are wanting please by all means post them so I know in the future.

Thanks,

pureftp can do the followings ?
1. assign bandwidth control, max. connection on a group and
assign user on that group . such that I don't have to set individual user

2. can it limit the ftp command ?
e.g. in proftp
<Directory /home/ftp/incoming>
<Limit LIST>
DenyAll
</Limit>
</Directory>

with this setting, after uses login, they can only see a empty directory. But actually, there are files inside.
