proftpd transfer disconnect issue
 

Hello,

I seem to be having a small issue w/ my install of proftpd. I'm not sure if this is the correct forum for this, but I'll post my question and move it if needs be.

To my question... I have installed proftpd 1.2.9 on my Fedora Core 1 box and everything is working great except one problem. Every time I try to download or upload something to my ftp site, proftpd decides that after 10 minutes I'm done. At first I thought is was a session timeout, but it isn't because I've stayed connected for more than 10 minutes. Then I thought it was a transfer size limitation, but I've sent successfully sent files to it (from my local network) and I've sent over 1GB to it and it still keeps accepting more. Each file took less than 10 minutes to transfer so I stay connected.

But whenever I start a big file transfer outside of my local network it ALWAYS quits after 10 minutes of transfering (both upload and download.) I've looked everywhere for help. Documentation, FAQs, Web searching, and I've searched the forums here and I cannot find anything to help me out. I've looked at all of the server directives and set all appropriated settings to eliminate the problem to no avail. It has to be something simple I'm missing.

After a week of working on this, I decided to start off fresh from the basic.conf file that comes w/ proftpd in the sample-configurations directory and started over from there, but no dice.

I AM running IPTables, but I've put rules in place to allow unrestricted access from the machines both inside and outside my local network. And I don't see anything unusually from the proftpd error log either.

Does anyone out there have any suggestions that I could try? I'll post my proftpd.conf file if necessary.

Thanks a million,
Chris

Try connecting to your FTP server from inside and outside your LAN but not doing anything, to establish whether it is a timeout.

If the problem only occurs when doing transfers from outside your LAN I'd look at the ISP's setup, e.g. are you using a proxy server to connect to FTP. They may be transparently proxying FTP traffic.

Passive mode can cause very flaky connections if it's not working correctly.

Same problem here, I'd be very happy if this case could be solved (know that you're not alone dudaman ;)!)

Interestingly enough, I noticed (well, I think.. the kernel log wasn't activated by default.. wtf) my Fedora core 1 reboots itself.
I'm getting a bit tired of fedora's bugs.
Hmm this post is a bit old, have you found anything yet?
