Proftpd woes

[karrot-x]

This has been extremely annoying for a long period of time. My proftpd server is extremely slow, 10-15 seconds to load a directory with 3 files in it, 10 seconds to upload a 2KB text file when the user has a 768kbit upload. I've tried many things and can't seem to find the problem.

Tried:
1. Increasing the buffer size allowed for the proftpd server.
2. Turning off ReversDNS lookups.
3. Turning off indent lookups.
4. Turning off Iptables firewall to see if that was the problem.
5. Rebuilt proftpd from clean sources to see if that was the problem.
6. Searched the net to see anything else.

All of the above has been giving me blanks. I hope that somewhere has expereinced this problem and knows how to fix it!

I am wondering if ServerBeach has some kind of network monitor level not allowing a certain amount of FTP bandwidth? Or is there something on the server network configurations that would cause this?

Thank you in advance,

I'm having the same problem. FTP is not working in any sense of the word. its slow, disconnects, times out, screws up the files being transfred, etc. takes 30 or more seconds to list a directorys contents, not realy dependendt on the contents more its just slow and broken.


I'm thinking its related to firewall issues.

any help?

Hey, I never found a solution to the proftpd problem but I did have great success with vsftpd. The moment I installed it solved the problem. I spent over 2 weeks trying to solve it with different methods and it just wouldn't budge. This is the best help I can give you. Also with the vsftp you're more secure :0.

Still trying to fugure out why the ftp is crippled. its really waseting a lot of time.

Does you have the ip_conntrack_ftp iptables module loaded? Most GUI FTP Clients (all of them probably) use passive FTP which requires the connection tracking to work properly.

Hi there all.
I have had this problem befor :bang: And has finally found the problem.

Server 1
- ProFTPD Version: 1.2.10 (stable)
- Scoreboard Version: 01040002
- Built: Tue Jul 12 21:36:42 SAST 2005

I have three network connections.
eth0 - Internal network
eth1 - Internet
eth2 - Wireless communaty

Whenever I disable eth2 everything works fine but as soon as eth2 comes back up ProFTPd goes into the slumps. Disabling it causes ProFTPd to run normally again.

Server 2
- ProFTPD Version: 1.2.10rc3 (devel)
- Scoreboard Version: 01040002
- Built: Fri Oct 1 08:33:21 SAST 2004

I have another Server standing right next to it with these connections
eth0 - Internet
eth1 - Internal network

Here I have exactly the same problem except that here it occur whenever I enable eth1 wich is the internal network.

Any ideas?
