"Operation not supported on socket" while mounting

[dberzano]

While attempting to mount a certain remote volume:

I am on Mavericks. sshfs version info:

> sshfs --version
SSHFS version 2.5 (OSXFUSE SSHFS 2.5.0)
OSXFUSE library version: FUSE 2.7.3 / OSXFUSE 2.6.2
no mount point

The same volume mounts correctly on Linux:

> sshfs --version
SSHFS version 2.4
FUSE library version: 2.9.0
fusermount version: 2.9.0
using FUSE kernel interface version 7.18

The remote SSH server runs on an Android device with OpenSSH_6.2p2 and the sftp service works just fine.

I am not sure if this is a sshfs problem or an OSX FUSE problem...

Thanks!

Similar behaviour here: sshfs on Mavericks works fine with OpenSSH_6.6p1 on Android. The describes problem occurs when the sshd is a Dropbear.

[mjfwalsh]

I get exactly the same error with both Dropbear (SSHDroid) and OpenSSH (6.1p1). Both servers work fine and work with ssh, Cyberduck and sshfs on linux (Ubuntu running on VirtualBox).

On OpenSSH I get

I get the same issue when trying to mount a phone running OpenSSH from Yosemite.

[intuited]

Same issue here when attempting to connect with sshfs (recently installed via brew) to two Android 4.x phones running SSHDroid. ssh and scp to the phones work without issues, as does sshfs to other (non-SSHDroid) hosts. sshfs to the phones from an Ubuntu client also works without issues. Running OSX Mavericks.

[dymk]

+1, OSX Yositmite 10.10, trying to sshfs into a phone running SSHDroid

sshfs --version
SSHFS version 2.5
OSXFUSE library version: FUSE 2.7.3 / OSXFUSE 2.6.4
no mount point

[bfleischer]

Please update to the latest version of osxfuse, @dymk. Version 2.6.x has been outdated for a really long time and does not even support Yosemite. Updating osxfuse to the latest version will not fix this issue but it contains a lot of other bugfixes.

[cimocimocimo]

+1 OS X 10.11 and latest devel version of spacemacs. Also using OSXFuse 3.7.1

I'm able to browse directories and open files from spacemacs but get the error:

basic-save-buffer-2: Opening output file: Operation not supported on socket, /Users/username/Sites/example.com/mountpoint/testing.txt

I AM able to edit and save this file using vanilla emacs through the command line however. This makes me think the issue is with Spacemacs somehow.
