TDE kftpgrabber and kasablanca FTP clients - connect, but no file list ever retrieved

All, I've testing both ftp clients in applications (kftpgrabber and kasablanca). Of the two, kasablanca will connect, but does not display any remote contents in the file areas. I can issue commands e.g. PASV, help, dir, and the log output shows the remote server sees the command and responds by changing directories remotely and issues the CWD response showing successful directory change, but no file listing is ever available. (tried both with/without [x] correct pasv) Here is the sample log window output: 220-Gesellschaft fuer wissenschaftliche Datenverarbeitung mbH Goettingen 220-==================================================================== 220-This is a Linux PC (Dell PE-2650, 2 CPUs P4/2800, 12 GB RAM) 220-running SuSE-Linux-8.2 with SuSE kernel 2.4.20-64GB-SMP. 220-/pub is ext3, a 2 TB Partition within a Transtec T6100F16R1 220-IDE/FC Raid array with 15+1 SATA disks Hitachi 240 GB Raid5 220- 220-For questions and other contacts to the ftp-admin, mailto:emoenke@gwdg.de 220-All transfers are logged.

PASV 200 Type set to A. list 227 Entering Passive Mode (134,76,12,3,232,67) I do not know where the list or transfer went, but it never made it into my window. I then tested with opensuse/kde3/kftpgrabber and I was able to connect and retrieve a directory listing and transfer files. The same with gftp, login to the same server and it works just fine. This looks like it may be a generic tde issue with ftp clients. This only effects applications/<ftp clients>. Konqueror ftp works fine in TDE. Type: ftp://david@server/home/david into the addressbar, the askpass dialog pops up and the connection and listing is perfect. So whatever kftpgrabber and kasablanca do differently is not working, but what konqueror does -- works! kftpgrabber likewise shows a connection with the remote server being made, but no file listing is ever displayed. The big issue with kftpgrabber is a race condition that occurs when the listing/handshake fails or when connection over ssh is attempted. It effectively locks the side of kftp the connection occurs on (left/right) and then pegs the CPU at 40-50%. Quitting kills the hung connection. A sample of the kftpgrabber connection log is: [01:53:37] KFTPGrabber logger initialized. [01:55:41] *** Connecting to nirvana:21...

Both clients show similar behavior - like some part of the ftp-ioslave isn't communicating correctly resulting in no listing. Can someone test and confirm this behavior. Thoughts? Suggestions? Small potatoes apps, but curious neither are not working. -- David C. Rankin, J.D.,P.E.
