Very strange problem !!!

MrPat · 10-03-2002, 09:43 AM

Hi, i know router problems have been discuss before, but i haven't seen something similar to my problem.

I have at home 2 computers. One is on Debian-Linux .. and uses ProFTPD. My network is behind a Linksys Router.

In my Forwarding Tables, i've forward Ports 20-21 TCP and UDP to my Linux computer's network adress.

When i connect directly to my server i can upload anything to it. But when i'm trying for example to transfer from site-to-site the transfer jammed at the STOR command. I dunno why, but even if i'm trying to send with the PORT command, it always enters PASS mode.

I tried to activate DMZ host on my Linux computer's network adress .. still no change !

Can somebody help me ??

P.S: My proftpd is configure to accept site-to-site .. coz on certain site-to-site-transfer, it works but only 10% of all transfers.

try adding the directive PassivePorts 50000 51999 (or any other range you want) to your proftpd conf file and then forward that port range to your linux box.

STOR ls-lr? wtf? thats not right at all.

MrPat · 10-03-2002, 12:38 PM

STOR ls-lR means .. STORING the file ls-lR

hehe sorry for the misunderstanding

Is your ftp server configured to allow site to site transfers. ProFTPD does not allow it by default.

ftp.uk.debian.org does not allow fxp transfers, however you may be able to get away with it since your ftp server is the same ip as you're connecting with the ftp client.

MrPat · 10-03-2002, 01:06 PM

My IP is not the same, because i'm at work now, and my ftp server is at home .. !! And yes I have enable site-to-site transfer with ProFTPD !

Do u have a ftp, where i could test, instead of Debian's ftp ?

Oh well then that's probably why it failed.

I am not aware of any public ftp servers that allow site to site transfers.
