SUMMARY Can't transfer files in Dolphin with ssh (fish). The transfer starts then after a few second, a dialog box appears "Could not write file". This corresponds with an event in the ssh access log (/var/log/auth.log) on the destination: Mar 21 00:49:13 server sshd[473651]: Received disconnect from x.x.x.x port xxxxx:11: disconnected by user Mar 21 00:49:13 server sshd[473651]: Disconnected from user user x.x.x.x port xxxxx Mar 21 00:49:13 server sshd[473392]: pam_unix(sshd:session): session closed for user user Mar 21 00:49:13 server systemd-logind[831]: Session 189 logged out. Waiting for processes to exit. Mar 21 00:49:13 server systemd-logind[831]: Removed session 189. This was tested on a variety of different files on a local, wired connection for both the target and destination. Also, there is a second problem. The speed for transferring a file 20x slower than scp. With scp the speed is is 20MB/s. With Dolphin sshfs (fish), it is 1.15MB/s. This speed is not useful. STEPS TO REPRODUCE 1. Create a fish connection in Dolphin. 2. open two tabs in Dolphin, one local tab containing the file to be copied and one remote tab. 3. drag the file from the local tab to the remote tab. 4. Observe that the file transfer starts then after a few second stops with the error reported above. OBSERVED RESULT Files can't be transferred, the transfer is always terminated. EXPECTED RESULT The file transfer should just complete. scp and sftp not using Dolphin work as expected. Dolphin sshfs does not work. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.24.1 (available in About System) KDE Plasma Version: 5.24.1 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Even if the disconnect issue is solved, the slow speed is still way too slow to be used. Please consider there are two issues in this issue report.
