Site to site FXPing problem

[Waazaap]

Hi,

I'm kinda new to FXPing but I got this:

- Windows NT stro (FXPable), wanna FXP to a Unix (non-FXPable)

I assume that I need to set the FXPable one to "uploading" and the non-FXPable to "downloading" right?
I'm not behind a firewall or a router. Just a hub.
OS is Windows XP Pro and I'm using FlashFXP 2.0 RC2 build 862.

The problem is that it looks like it is going to start, but it freezes at the STOR command.
It looks like this:

TYPE A
200 Type set to A.
PASV
227 Entering Passive Mode (193,219,146,68,12,41).
LIST -al
150 Opening ASCII mode data connection for file list
226 Transfer complete.
TYPE I
200 Type set to I.
PASV
227 Entering Passive Mode (210,121,128,12,11,129).
PORT 210,121,128,12,11,129
200 PORT command successful.
STOR kal-slam.002
550 kal-slam.002 : Overwrite permission denied
Transfer Failed!

I don't get it since I'm a FXPing n00b, please help! ;)

TIA!

550 kal-slam.002 : Overwrite permission denied
seems like you don't have permision to write to that dir. contact site admin and make sure all permisions are set correctly

But do both FTP's have to be at PASV mode or just always one? And which one, the receiving FTP or the sending FTP? :confused:

[MxxCon]

for fxp to work one site must be in pasv mode and one in regular (port). which one is depends on networking config. if both sites require that you connect using pasv mode, like firewalled servers, then fxp between them will not be possible.

[Waazaap]

And how about the advanced settings, I mean the "uploading" and "downloading" tabs?

Uhm, am I nuts here or ...
in the first post he says, unix isn't fxpable, .. so why fxp with it?

[Waazaap]

Well cause the NT one is FXPable.

NT (FXPable) -> UNIX (non-FXPable) should work right?

[MxxCon]

no
both sites must support fxp in order to work

[Waazaap]

Thanks for helping me out dudes, I'm just an FXP n00b lol.
Just the last few questions:

NT -> UNIX and vice versa, both sites must be FXPable or do they both always have to be FXPable in order to FXP?
Because I have read multiple times that just 1 has to be FXPable in order to FXP.. :confused:

And what do I need to do with the advanced options like "uploading" and "downloading"?

Thanks for helping me out! :D

FXP works by simulating pasv upload/download on one site and "active" download/upload on the other.
in order for FXP to work sites must allow for PORT command to have ip other than the one used during login and must accept incoming data connections from ips other the one used during login.
it is possible for a site to allow only port w/ other ip OR incoming connecitons from other ip, however with most ftpd if FXP is disable, both of these "features" are disabled.

i don't want to sound like i'm brushing you off, but consider reading some ftp RFC's. there are not extremely complex and will let you understand what exactly is going on during ftp/fxp session.

It all comes down to the network configuration, and the way each admin configured his FTP. As far as I know there is no sure way to know if 2 FTP's can perform FXPing but to try it yourself.
