SFTP - CyberDuck doesn't work, but WinSCP does? Server exited on signal "PIPE"?


I'm having issues connecting remotely to a server. Here are the details:

I am running Mac OS X Server, 10.4.11. The G5 (the server in question) is located in the main building and we have a satellite office that connects to it via SFTP. We have both PCs and Macs. Macs would connect using Cyberduck, and PCs connect with WinSCP. After doing some updates yesterday (not 10.4.11, but stuff like Quicktime, iTunes, Java, maybe Security update but I don't remember, etc), Cyberduck cannot stay connected. WinSCP does not have a problem.

Thinking that it may be a Cyberduck related issue, I tried other software like FireFTP (Firefox add-on), CuteFTP and sftp itself from the command line. I notice that it does successfully connect, but then terminates the connection.

Something interesting to note: my admin user, which is the only "local account" does not have any problems. I can connect with all the above stated programs.

Also, I can connect via ssh with any user as well via the command line.

I ran sftp -v from the command line and noticed that I was in fact connecting to the server, then being disconnected. Here are some of the errors I receive:

sftp -v user@myserver.com
....
....
....
debug1: allot of stuff before this then the interesting part -
debug1: Next authentication method: keyboard-interactive
Password:
debug1: Authentication succeeded (keyboard-interactive).
debug1: channel 0: new client-session
debug1: Requesting no-more-sessions@openssh.com
debug1: Entering interactive session.

debug1: channel 0: free: client-session, nchannels 1
debug1: fd 0 clearing O_NONBLOCK
Transferred: sent 1968, received 1928 bytes, in 0.1 seconds
Bytes per second: sent 31433.7, received 30794.8
debug1: Exit status -1
Connection closed

Also, I can't recreate the error I got at one point, but I also received an error stating:

Server exited on signal "PIPE"

Any ideas?

Thumbs down Update

The fix was very, well, un-Linuxish.

I downloaded 10.4.11 Combo Updater and installed it. After a reboot, all was well. I believe that the previous updates I did had something to do with the issues.

Sorry to post Mac issues on the Linux boards, but I really thought it had something to do with SFTP.
