sshfs: permission denied when trying to access specific folder

Question

I can access to my specific folder like this:

ssh -YX  xxx@xxxxxx.xxx.xxxx.xx
cd ../the/folder/I/want   

or with an absolute path

ssh -YX  xxx@xxxxxx.xxx.xxxx.xx
cd /the/absolute/path/to/the/folder/I/want

However I can't lsit from my distant home directory

ssh -YX  xxx@xxxxxx.xxx.xxxx.xx
ls ../the/folder/I/want 
-> ls: cannot access ../the/folder/I/want: No such file or directory

I can mount and access to my home folder with sshfs. However, if I try to mount the specific folder with sshfs, for instance:

sshfs xxx@xxxxxx.xxx.xxxx.xx:/the/absolute/path/to/the/folder/I/want   ~/mountpoint

I can see the mounted folder, but I have no permissions to access it. This is the result of ls -l local command:

d---rwx--- 1 root wheel 4,0K 4 nov 22:46 mountpoint

Is there a way to mount this specific folder?

Answer 1

This happens when there are folders that only give access to specific groups. Then sshfs can fail to see that one of the IDs in that group belongs to the user that mounted the drive.

You just have to add the option "-o defer_permissions", e.g.

sshfs -o defer_permissions xxx@xxxxxx.xxx.xxxx.xx:/the/absolute/path/to/the/folder/I/want   ~/mountpoint

It was a problem of permission. The issue was finally resolved when the administrator gave me all permission on the distant folder.
