hi,

i'm having the same problem as here #1671, but deleting the known_hosts did not help.

further more, i see, that with every "yes, store the key forever" klick, the key of the ftp server is added known_hosts again.
so i have a known_hosts with a lot of identical entries now.

any suggestions?

those are the only errors i see in the console:

11.11.11 22:44:48,081 Cyberduck: Error loading /Users/user/Library/Contextual Menu Items/Disk Inventory X Finder CM.plugin/Contents/MacOS/Disk Inventory X Finder CM:  dlopen(/Users/user/Library/Contextual Menu Items/Disk Inventory X Finder CM.plugin/Contents/MacOS/Disk Inventory X Finder CM, 262): no suitable image found.  Did find:
	/Users/user/Library/Contextual Menu Items/Disk Inventory X Finder CM.plugin/Contents/MacOS/Disk Inventory X Finder CM: mach-o, but wrong architecture

i'm running lion 10.7.2 and cyberduck Version 4.1.3 (9045)

i remember, having this "trouble" with snow leopard too. that was an earlier version of cyberduck.

the ftp-server shows: 220 NASFTPD Turbo station 2.x 1.3.2e Server (ProFTPD)
(its a qnap nas)

Can you login to a guest account in OS X and test if you get the same trouble.

Please reopen the ticket if you can provide more information. I actively close tickets that miss a timely response as it is unlikely to find a resolution then. In this case I just have no idea what might be going on and can only do wild guesses not much educated. We have to narrow down the possible causes and the first step is to try it with another account.

Hello, i have exactly the same problem;
The problem seems to occur when the SSH server is running on a non-default port. For example my SSH server is running on port 11111 instead of 22.

Steps to reproduce:

  • Delete ~/.ssh/known_hosts
  • Connect to mypc.homeip.net:11111
  • Unknown host key -> check 'always' -> allow
  • 1 line added to ~/.ssh/known_hosts
  • Disconnect
  • Connect to mypc.homeip.net:11111
  • Unknown host key -> check 'always' -> allow
  • 1 line added to ~/.ssh/known_hosts (total = 2 lines now)
  • Disconnect
    This continues forever, always adding another new line to the known_hosts.

So my guess is the problem probably has got something to do with the hashing of:

[mypc.homeip.net]:11111 ssh-rsa <hostkey>

for hosts with non default ports, versus:

mypc.homeip.net ssh-rsa <hostkey>

for default ports.

We do not take the server port number into account when verifying or adding keys, though.

I have tested here with running OpenSSH on port 222 on localhost with an empty known_hosts but cannot reproduce.
