In case you need to mount a remote folder so you can work with it like a local folder:

sshfs  navpex:/home/navabi/ai_sim_model/ ./navpex_folder/

This command uses the navpex ssh alias from the ssh config to mount the remote folder ai_sim_model as the local folder 'navpex_folder'. Under the hood SFTP is used to realize the access, but of course a the current user needs public-key access to the host iself.

To unmount the folder:

fusermount -u navpex_folder
