Mount with sshfs and write file permissions

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 Clarification 0 ------ In response to user3188445's comment: $ 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/ total 216 drwxr-xr-x 1 699 699 4096 Aug 12 16:42 . drwxr----- 58 LOCAL_USER LOCAL_USER 4096 Aug 17 15:46 .. -rw-r--r-- 1 699 699 2557 Jul 30 16:48 sample_file drwxr-xr-x 1 699 699 4096 Aug 11 17:25 sample_dir $ touch test_mnt/new_file touch: cannot touch ‘test_mnt/new_file’: Permission denied # extra info: SSH to the remote host and check file permissions $ ssh REMOTE_USERNAME@REMOTE_HOST # on remote host $ ls -al /remote/dir/path/ lrwxrwxrwx 1 root root 18 Jul 30 13:48 /remote/dir/path/ -> /srv/path/path/path/ $ cd /remote/dir/path/ $ ls -al total 216 drwxr-xr-x 26 REMOTE_USERNAME REMOTE_USERNAME 4096 Aug 12 13:42 . drwxr-xr-x 4 root root 4096 Jul 30 14:37 .. -rw-r--r-- 1 REMOTE_USERNAME REMOTE_USERNAME 2557 Jul 30 13:48 sample_file drwxr-xr-x 2 REMOTE_USERNAME REMOTE_USERNAME 4096 Aug 11 14:25 sample_dir
