I want to mount an sshfs folder at boot under Mac OSX: I'm using Macfusion right now, that is a GUI for MacFUSE, but I have to mount the folder manually.
How can I achieve that?
If you maintain a remote machine, it can be really useful to mount that machine's filesystem locally to move files around. MacFuse and
First, make sure you can ssh to your remote machine without entering a password. Do the setup in Leopard finally supporting ssh-agent at login and verify that it works:
If it logged you in without prompting for a password or passkey, you're ready to proceed.
Figure out where you want to mount your remote volume. I wouldn't recommend using
mkdir -p /mnt/HOSTNAME
(Obviously, you'll replace
Then make sure you can mount your remote site as a volume without specifying a password using
Set VOLUME_NAME to whatever you want your volume to be named in the Finder. I used HOSTNAME. PATH is optional; set it to whichever directory you want to mount on the remote host. If it's not set, it'll use your home directory.
If you get no error messages,
and when you do an
Unmount the volume you just mounted:
Now comes the tricky party. You'll need to create a LaunchAgent item to mount your volume at login. This in itself is pretty easy. However, if your system is anything like mine, this item won't have its SSH_AUTH_SOCK set properly, so it won't be able to login to the remote host without using a password. You'll have to manually set the SSH_AUTH_SOCK yourself.
First, create a wrapper around
Basically, this file sets SSH_AUTH_SOCK to the most recent socket in your tmp directory. In most cases, this should be the proper one. It's unlikely to fail, and there's no security issue if it does.
Now you can finally create the launchd plist file. Put this in
(If your host's path is, say,
Now load the plist file and run it to see if it works.
If you see no error messages, see if the volume was mounted properly:
If your remote files show up, then great! You're done!
If not, use
to unload the file before making edits to it, then use
I'd like to add something to dag729's very complete answer.
If you have Lion and have now OS X Fuse instead of the old MacFuse, then the procedure above won't work out of the box because the path of sshfs is different.
If that's the case for you, look where sshfs is in your installation using
and put that path in the /opt/local/bin/sshfs-authsock script.
In my installation, that path is /usr/local/bin/sshfs and therefore my script is:
I can confirm that the rest is still valid.
