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

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@

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?

Remove the known_hosts file:

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

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

This removes all keys, not just the problematic one. – scai Feb 11 '13 at 12:59
  1. close Dolphin
  2. open terminal and enter:
    $ ssh-keygen -R
  3. open Dolphin and enter into the address bar:
    (the port number is optional since it is the default 22 in this case)
  4. Click "yes" to the dialog that comes up

If you have a non-standard port number on the remote server, the IP address is not enough. You need to include it in step #2 (brackets and quotes are all part of the command): ssh-keygen -R '[]:22200' – IQAndreas Dec 1 '15 at 15:52

use fish://user@

instead of sftp and it'll work just great.

you can also set up your ~/.ssh/config to store ip, username, port etc so then you can just type fish://myserver/ in dolphin

Don't know why this answer is downvoted. I tried and it works. Just choose fish not sftp in the Add Network Folder dialog. – pram Feb 8 '14 at 17:25
Worked for me (the other option not involving removing all keys did not), now can anyone explain why? – erb Jul 4 '15 at 14:25
