sshfs – mount files over ssh

Mount a file system on a different computer via ssh:

sshfs -o follow_symlinks user@server:/home/user/ /path/to/mount/point

server is the other computer, user is your username on the other computer and /home/user/ is the folder you want to include from the other computer. /path/to/mount/point is the place on your drive where the files will be located. It needs to be a folder that exists and is empty.

To get rid of the mounted folder again use

umount /path/to/mount/point

Executing a command on a remote server

This is probably a very old hat for Linux-savy people. You can use ssh to execute commands on a remote server, just pass them on as an additional argument:

ssh me@my.server.de "cd bla ; ls ; python test.py "

I use double quotes (“) istead of single quotes (‘) to interpret variables. Different commands are separated with semicolon (;). You can use any command you like, but for some reason when I call some GUI I don’t get the output on the command line until the window is closed.

Open SSH folder in Dolphin using a SSH-key

Dolphin allows you to connect to folders on other machines per SSH, but there is no option to specify a key file. But you can add the key to your general SSH configuration (with the added benefit that you also won’t have to specify the keyfile anywhere else, no more -i on the command line!). This is how it works:

  1. Locate your private key file, say it’s ~/.ssh/myidentity_rsa.
  2. Open or create the file ~/.ssh/config and add the lines
    Host myhost.net
      HostName myhost.net
      IdentityFile ~/.ssh/myidentity_rsa
    
  3. Type fish://user@myhost.net/path/to/folder/ into the location bar.
  4. Now it should ask for the passphrase to your key.

Done!
