Large Files With Apache and Anon FTP

[jspilon]

Hi all,

I need your advice and help ! I have customers that need to store and transfer large files. When they do so it knocks down my server . What i would like to know how to do and to know if possible:

- Limit number of connections to a file
- Limit resource to file downloads ( bandwith, etc.. )
- Is it better to have customers use anon ftp instead ? less resources are used ?!
- Disable memory caching of larger files than x MB ...

If you have any other suggestions please send them in, if you know any of the things above please help!!! =)

Regards,
jspilon

What problems do you experience? High bandwidth or many processes?

There is more process than usual and i ping the server for over 1100 ms responses... as well as the server to respond very slow

machine has 1gb ram and is celeron 2.4

thanks

You should check using the following ProFTPD control directives (/etc/proftpd.conf)

MaxClients -- Limits the number of users that can connect
MaxClientsPerHost -- Limits the connections per client machine
MaxClientsPerUser -- Limit the number of connections per userid
MaxConnectionRate -- Maximum TCP socket connection rate
MaxHostsPerUser -- Limit the number of connections per userid
TransferRate -- Configure upload, download transfer rates
RLimitCPU -- Configure the maximum CPU time in seconds used by a process
RLimitMemory -- Configure the maximum memory in bytes used by a process
RLimitOpenFiles -- Configure the maximum number of open files used by a process

Complete docs at:
http://www.proftpd.org/docs/directives/linked/by-name.html

I don't believe that using Anonymous would gain you any noticeable amount on resources.

Also I would not use a Celeron CPU, except on a test server...

Would CacheMaxFileSize Directive help me prevent large files from being cached to memory ?
