On 8.1 (KDE 4.4.5) I used Dolphin on my local PCBSD box to do file operations on a remote server using the FISH protocol. After upgrading to PCBSD 9 (KDE 4.7.3), when uploading files to the server (specifically drag and drop from one pane - local, to another - remote), only part of the file makes it (about 80%), reporting an error, "Connection to the host XXX is broken". Same problem exists in Konqueror. No problem uploading files using SCP from the console however, and no problem using FISH with other file operations like move ,copy, delete, or downloading files. I had no problems using FISH with Dolphin using KDE 4.7.4 on Ubuntu 11.04 with the same remote server. No problems uploading files with Filezilla. Does not appear to be a KDE issue unless it was fixed in 4.7.4 but I could find no discussion of this on KDE. Not sure how to troubleshoot this.
