Connect to FTP/SFTP in Dolphin or transfer Nautilus Bookmarks

On the left hand side of the Dolphin window, click Network. There will be a item for adding a network location like ftp or scp. Dolphin is a great file manager...

If you just want a quick connection, you can click the navigation breadcrumbs on above the file list (or Ctrl+L) and type directly:

sftp://{username[:password]}@{domain}/{path}

SFTP in Dolphin is implemented as fish

fish://{username[:password]}@{domain:port}/{path}

If you want to connect using a key file.

1. create a config file in path ~/.ssh/config

2. config file may look like this

   Host <any-host-name-of-your-choice>
        HostName <provided host name, must be the address>
        User <username to login>
        Port <if you have a port, else remove this line>
        IdentityFile ~/.ssh/<valid key path>.key
   

3. Save the file, in Dolphin Address bar type sftp://<any-host-name-of-your-choice>

4. this will connect to server using dolphin and private key file.

1. On the left hand side of the Dolphin main window, is a network link
2. Click on the network link
3. There will be a symbol for adding a network folder, double click it and a pop up window will happen.
4. Select ftp option from the list and another new window will pop up.
5. You are now at the Net Work Information place. Type a name for your network folder.
6. Next enter your user name.
7. Then enter the server name.
8. Press the save and connect option.
9. A pop up will appear and will hang, will play pretend its working for infinity
10. Could never get it to work.

I am not sure how exactly Dolphin works, seems like its using KIO under the hood so:

sudo apt install kio-extras

Added sftp for me.
