DOpus makes too many connections on FTP sync

Hi Forum,

I'm trying to sync folders with large numbers of small files from my hard disk to a FTP location. I have to use the folder syncronization dialog in DOpus to do that since many (thousands of) files are already online.

Every couple of minutes DOpus looses connection and I have to wait like 10 minutes until I can re-open the FTP session. The server says that I have too many connections already open (obviously it only allows like two simultaneous connections).

Is there anything I can do about that in DOpus?

I have the same issue, when uploading to my media server (TViX). It only allows one connection. It happend just now, when I created a new folder. I have to manually reboot the TViX to gain FTP access to it again.

Sincerely

This is more a problem with the server. Possibly you need to get the admin to allow you to have more than one connection.

DOpus only opens connections as needed and for a synchronize it will generally only use one connection. Generally O[pus will reuse the same physical link if it can unless you try to do multiple things on the one link, such as copy a file then force a directory read of another folder.

Have a look at the FTP Log and see if you can close down any excess connections before you start the synchronize copy.

Thanks for your response

The firmware of the TViX hardware device only allows one connection, and will block if you start another connection. I started the connection in one tab in one lister and didn't try to do multiple things (as I have had this problem before). I just changed directory and created a new folder, when Opus created a second connection, which blocked the TViX.

From my ftp log

250 Changed to /disk1/Series
257 "/disk1/Series"
257 MKD command successful.
Opening Connection 192.168.1.110:21
Timeout on Command 1001
See FTP Log for more details.
Connection closed
Opening Connection 192.168.1.110:21

In this case there is no need for Opus to create a second ftp connection. Could there be something in my configuration that courses a refresh that makes a second connection?

I don’t think that this is a problem with the server. You cannot expect ever system admin in the world to allow an unlimited amount of ftp connections just because a user’s ftp program requires it to function.

I have used Opus for my Tivo and have not seen the specific issue.

But, yes some servers will only allow one connection. From the log you give, I'm not quite sure what you are seeing. The server is timing out the connection so when you do the second action, Opus does not actually have an open connection so it is making the connection again, maybe.

Set the server to have longer timeouts, or turn on NOOP keep alives in Opus FTP prefs.

Talk to me privately via direct email with some more details and I can look at it further.
