I try to sshfs mount a remote dir, but the mounted files are not writable. I have run out of ideas or ways to debug this. Is there anything I should check on the remote server?
I am on an Xubuntu 14.04. I mount remote dir of a 14.04 Ubuntu.
local $ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty
I changed the /etc/fuse.conf
local $ sudo cat /etc/fuse.conf
# /etc/fuse.conf - Configuration file for Filesystem in Userspace (FUSE)
# Set the maximum number of FUSE mounts allowed to non-root users.
# The default is 1000.
#mount_max = 1000
# Allow non-root users to specify the allow_other or allow_root mount options.
user_allow_other
And my user is in the fuse group
local $ sudo grep fuse /etc/group
fuse:x:105:MY_LOACL_USERNAME
And I mount the remote dir with (tried with/without combinations of sudo, default_permissions, allow_other):
local $sudo sshfs -o allow_other,default_permissions -o IdentityFile=/path/to/ssh_key REMOTE_USERNAME@REMOTE_HOST:/remote/dir/path/ /mnt/LOCAL_DIR_NAME/
The REMOTE_USERNAME
has write permissions to the dir/files (on the remote server).
I tried the above command without sudo, default_permissions, and in all cases I get:
local $ ls -al /mnt/LOCAL_DIR_NAME/a_file
-rw-rw-r-- 1 699 699 1513 Aug 12 16:08 /mnt/LOCAL_DIR_NAME/a_file
local $ test -w /mnt/LOCAL_DIR_NAME/a_file && echo "Writable" || echo "Not Writable"
Not Writable

$ whoami
LOCAL_USER
$ cd
$ mkdir test_mnt
$ sshfs -o allow_other,default_permissions -o IdentityFile=/path/to/ssh_key REMOTE_USERNAME@REMOTE_HOST:/remote/dir/path/ test_mnt/
$ ls test_mnt/
I see the contents of the dir correctly
$ ls -al test_mnt/
