Connect without VPN

If you are sitting at CBMR, you can connect directly to the server without VPN. If this doesn't work by default you can do the following:

1. Disconect cable network
2. Open Keychain Access on your Mac
3. Use the search bar to search for net.ku.dk when under the "all items" tab, under the default keychains-login window in the left hand side
4. Delete the found certificate
5. Put in the network cable again
6. A prompt will appear, and ask you to login. use [email protected] and your normal KU password

Mount the server locally

You can mount the server locally, so you can browse files via you your Finder via sshfs.

If you have a newer Apple Silicon Mac (M1 or newer), you need some additional actions to enable sshfs, described here:

Once installed, you can mount the server via:

sshfs [email protected]:/ /Users/abc123/esrum -o transform_symlinks -o follow_symlinks -o defer_permissions
