#1196 closed defect (wontfix)

Connection closed due to timeout while transferring extremely long files

There is a problem with transferring extremely long files (multiple gigabytes in size) that the connection gets closed during the transfer. My assumption is that there is a timeout on the server side that closes the whole connection when no command (is there a separate command channel?) gets sent for a given time. It's not the problem of the current file position because the transferred size is always less than 2GB (so it's not a 32 bit number limitation).

Have you tried the setting in Preferences > Connection > Send no operation to keep connection alive?

Yes I tried this setting (I tested it with both being set/cleared).

  • Resolution set to wontfix
  • Status changed from new to closed

You might want to try a SCP transfer or find out what setting is causing the server to close the connection. (There is no seperate command connection for SSH).
