I'm trying to mount the home directory of the login node of the batch system at my office on my local machine using sshfs. However, when I run

export LOGLEVEL=DEBUG3
sshfs remotehostname:/user/myname $HOME/mounted/loginnodehome -o sshfs_debug

I just get this as an output:

SSHFS version 2.8

and then nothing. The command does not return, and I get no further output. I assume I have misconfigured something, but I really don't know what that could be, and I would need some hints as to where to start debugging this. Any suggestions?

Details: My home machine is running ArchLinux, the remote machine is running SLC6. Both use zsh as default shell. I have configured passwordless ssh using the standard PGP key method. I'm ready to provide further details on request.

    Try ssh or sftp to the same remote host, with -v. That will probably hang in the same manner as sshfs and for the same reason, and it will be clearer what the problem is. – Celada Mar 12 '17 at 12:23
  • Simply using ssh on the same remote host works flawlessly. About sftp I don't know, I've never used it. Could you provide an example command line to test? – carsten Mar 12 '17 at 12:27

    sftp remotehostname is the command to test. – Jakuje Mar 12 '17 at 12:35
  • sftp remotehostname hangs. Authentication seems to work, but using -v the last line is debug1: Sending subsystem: sftp – carsten Mar 12 '17 at 16:07

The problem is solved now. It was related to the authorized_keys file on the remote host, which read

command="/bin/zsh" id-rsa ...

Such that sftp andsshfs would try executing zsh upon login/authentication. Removing the command=... bit such that every line would start with id-rsa ... solved the issue.

I encountered the same problem. It turned out that I was trying to start sshfs, from inside a directory that no longer existed. That is, on the machine where I was running the sshfs command:

md -p /media/$USER/nomi && sshfs -o gid=$GID,uid=$UID nomi: /media/$USER/nomi

My current directory was inside a directory of a previously mounted sshfs, that ceased to be mounted. (I'm using sshfs to mount the hard drive of my laptop on my stationary computer, and the previous such mount got dismounted when I left my home with my laptop in hand. – Giving me trouble after having returned home with the laptop again, and trying to remount it.)

The solution in my case was simply to precede my the sshfs mount with a cd to my home directory (or any other, actually existing directory), like so:

cd
md -p /media/$USER/nomi && sshfs -o gid=$GID,uid=$UID nomi: /media/$USER/nomi
