Thank you all anyway
]]>Why don't you need a "username@" in fstab in this case?
I assume that it didn't cross the OP's mind that this command is not run as a normal user (his own user). If using sshfs from the command line, you can run it without specifying the username if it is the same on both machines. Of course, unless the OP is accessing the remote machine as root, this would not be the case.
