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://[email protected]: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?

Solution 1

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://[email protected]: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

Solution 2

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.

Solution 3

use fish://[email protected]:22/home/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

This removes all keys, not just the problematic one.

Worked for me (the other option not involving removing all keys did not), now can anyone explain why?

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 '[10.3.140.111]:22200'

FISH is a different (but very much alike) protocol than SFTP. More info here en.wikipedia.org/wiki/Files_transferred_over_shell_protocol My guess is that FISH has a different preference for SSH keys than SFTP? but that's all I can come up with

FISH didn't work for me and the error message was vague and unhelpful, SFTP did work for me after fiddling with my known_hosts file.
