-problem with FTP connection

[Dennis41]

I start a previously saved FTP connection session. Password is required so I put it on. After a while the FTP connection dialogue disappears and nothing happens - no connection, no error or whatsoever message. Tried several times, still the same result. Two hours earlier it worked correctly! I mean - I was connected.
Using Total Commander 8.50 beta 15, WinXP Service Pack 3, 32 bit

Please turn on logging in Configuration - Options - FTP, then try to reproduce the problem and post the log here. You may replace sensitive names by others, but please do not delete anything.

I discovered that this problem occurs when I have an USB stick connected to PC. Strange behaviour. When I disconnect the USB stick the FTP connection works again.

OFFLINE4 is a connection timeout - TC 8.01 have a fixed timeout of 10 seconds.

Since you are using 8.50 beta, you can increase the timeout:

Please add the line
DataConnectTimeout=30
to the file wcx_ftp.ini, section [General]

You can edit the wcx_ftp.ini via Configuration - Change settings files directly. Make sure to add the line to the wcx_ftp.ini, not to the (also opened) file wincmd.ini.

I changed the settings according to your instruction and it seems that the problem is solved. At least the FTP connection for the time being I tried it was working fine, even with the USB stick connected to my PC.

Thanks for your help and for your time. Keep up the good work with Total Commander!!!

I just checked my code - there was no timeout at all in TC 8.01 and older, so an ftp connection could hang forever. It has been set to 20 seconds in TC 8.5 for these calls, not 10. I have increased it to 30 seconds now (for the next beta) for calls during the connection phase. I don't want to remove it completely, so I can detect a hanging connection and try to reconnect automatically.

Maybe it would be useful to set this timeout for 10 seconds as a default value and also give the user possibility to change to a few different options in the "Configuartion | FTP"
