#1793 IOProtocolExt needs timeout

Jeff Fritz

I have a trigger to synchronize with a remote kdbx via IOProtocolExt using scp.

For some reason or another (my guess is network issues), occasionally when I trigger the sync --

the status bar sits at "Uploading file..." and the Sync window sits at "Synchronizing... (Saving database...)" and does nothing until I kill the keepass process. Cancel button is greyed out at this point in time.

suggest some sort of timeout or cancel button that is not greyed out.

Using Windows 7 x64, Keepass 2.23, IOProtocolExt

    I tried again after the above error. The trigger was somehow disabled and I had to re-enable it. The problem happened again and attached is a screenshot of a debug message.

    Perhaps this is an issue with my individual sftp connection (not scp as I thought previously). Either way I suggest the following:

    • would be great if some more detailed/useful/user friendly output could be shown
    • how do I tweak the referenced "Optimize connection buffer size" option? Can't find it anywhere.

    One more minor note. Again, not sure if this is a problem with my openssh/remote_backups user configuration or if it is a IOProtocolExt issue.

    After doing this attempted synchronization twice, there are many ssh connections left open by the attempted synchronizations (see screenshot). Wondering if there is exception handling to clean up any open connections if a sync is not successful.

    For the initial connection attempt, you can specify a custom timeout in 'Tools' -> 'IOProtocolExt Options'. For broken connections, WinSCP's default reconnect timeout is 120 seconds.

    Best regards,
