Proftpd is slow ftp server ?

centosfan · 12-21-2007, 08:27 AM

I have ubuntu server installed and custom coded control panel with proftd.
When i login to ftp it took 10 second to load which suck,i want to load it instantly.Should i simply install other ftp server and put it on another port to get instant load ?I have only one site on server and i am only user so i realy dont need feature of creating ftp account in control panel.What ftp server you would reccomend for ubuntu server ?

Proftpd is not slow at all, not on my system at least. It loads instantly and transfer speeds are amazingly fast. Are you sure that it is properly configured? How did you edit the proftpd config file in /etc? Here is my proftpd.conf from my previous Ubuntu; bear in mind that this was for internal use only and that you will need extra security settings if you want your server to be publicly available:

Well i think reason of slowness is beacuse host uses custom coded control panel for ubuntu and that cp install apache and all other componentes so i guess it install and configure ftp server(since you can add usernames in cp)
Here is copy paste of conf file:

Sounds to me like reverse DNS resolving problem, try turning it off.
Sorry, I can't recall an exact one-liner solution but it certainly did the trick for me, try looking to official site and documentation.

Add this line to your proftpd.conf:

UseReverseDNS off
