Kubuntu cant add new ssh network folder

Question

I'm trying to add a remote ssh network folder in Kubuntu 11.04.

I can connect to this remote server via konsole ssh

: ssh 10.3.140.111

However when I try and add a "new network folder" from the network section of dolphin I get the following error message

Unable to connect to server. Please check your settings and try again.

Trying to connect using konsole and dolphin...

: dolphin sftp://user@10.3.140.111:22/home/user

gives me another error:

Connection to host The host key for this server was not found, but another type of key exists.

An attacker might change the default server key to confuse your client into thinking the key does not exist.

Please contact your system administrator.
is broken.

I can't seem to find any help for this issue, any ideas?

Answer 1

Remove the known_hosts file:

user@nixbox:~$ cd ~/.ssh
user@nixbox:~/.ssh$ ls
known_hosts
wolf@nixbox:~/.ssh$ rm known_hosts

Then try to add folder again and click 'yes' for the key. The file will automatically be recreated.

Answer 2

1. close Dolphin
2. open terminal and enter:
   $ ssh-keygen -R 10.3.140.111
3. open Dolphin and enter into the address bar:
   sftp://user@10.3.140.111:22/home/user
   (the port number is optional since it is the default 22 in this case)
4. Click "yes" to the dialog that comes up
