POSIX Error 51 (11 posts)

    I'm connecting via Fetch to an Apple Xserve running 10.6.3. I configured the FTP service to use FTP Root and share Points. I set up an ftpuser and a Share FTPshare. I gave the box a 192.168.1.33 inside address. In the router I mapped an outside address to point to the 192.168.1.33 address. When I connect inside using the .33 address I can get in via Fetch without issue, I can get and put files. If I connect via the outside address I get. "connecting - POSIX Error 51, entering passive mode, 192,168,1,33,106,4. I'm connected but can't see any files. Can anyone let me know what's going on here? thanks, Rick

    Hi Rick,

    In order to give the best advice, we'd like to see a full transcript of your attempt to connect to the server with the outside address.

    So could you please do the following?

    * Quit Fetch.
    * Open Fetch again.
    * Try connecting to your server.
    * After you receive the error, go to the Window menu, and choose Fetch Transcript.
    * Copy the entire contents of the transcript window, and paste them into a reply to this message.

    We'll take a look and see if we can provide advice.

    Thanks,

    Hi Rick,

    Running an FTP server on a private IP address (e.g. 192.168.1.33) is difficult. In the transcript above your server told Fetch to make a passive mode data connections to port 4222 of 192.168.1.33, but of course that address is not accessible outside your network. Fetch tries to be clever and attempts to connect to port 4222 at 98.110.127.9 (your public address) instead, but your router does not know to forward that connection to your server.

    I would look into configuring your FTP server to use a certain range of ports for data connections (e.g. 4000-4999). Then configure your router to forward all of those ports to the Xserve at 192.168.1.33.

    Let us know how it goes.

    Thanks,

    Jim,

    I added ports 4000-4999 as you suggested on the router to point to 192.168.1.33.

    I turned on the OSX server firewall and added those ports as well. This is what I got.

    Did it now try using port 43458?

    Hi,

    You need to configure the FTP server to only use ports 4000-4999 for passive data connections, since those are the ports that will be forwarded from the router to the server. I do not know off the top of my head how to configure the Xserve FTP server to only use certain ports. If you do not find that information in the documentation, let me know, and I'll see if I can help.

    Thanks,

    Hey Jim:

    O.K. I tired turning on the OSX server firewall and opening up those ports 40000-49999. I changed the port mapping on the router. Didn't work so I ditched the OSX firewall.

    This is what I get:
    Using 192.168.1.33 - I get in and can get and put files, no problem. I try it via the outside address and I get the following:
    Connecting to 98.110.127.9 port 21 (Mac OS X firewall is allowing connections) (4/13/10 2:35 PM)

    It says connected but I can not see any files or put any files. I'm close.....close doesn't cut it.

    Thanks,

    Do you have access to the server logs? Do see any information there?

    Thanks,

    Jim / Sott:

    I wanted to get back you and let you know I think I figured it out ( Maybe ).

    I think I was getting the POSIX 51 error because I was running Fetch from my Mac that was on the non routing I.P. sub net 192.168.X.X then telling fetch to go to the outside address then back in port mapping to the 192.168.1.33 address. I found this out by connecting into my home mac via back to my mac then running Fetch from there and BAM! no problem with POSIX errors! I hope that I was clear? Does that make any sense?

    Thanks for your response,
    RIck
