That is not a 1.
That is a lowercase L
For even more detail, do this:
ls -ll
It will list files, sizes, creation dates, ownership, and any symbolic link relations.
Also, a degree in computer science is not needed, but a passing understanding of how a linux box works kinda is, since that is what this really is.
In a nut shell, it looks like files were created by different linux users. (The OS uses special users and groups that are baked into the box for various purposes, most notably to give running software an identity to run under. Files created by those pieces of software will have the file’s ownership assigned to that user account they were run under. Samba, the window file share service, respects linux file ownership and permissions. If the samba user you are logging in as does not have appropriate access to the file, samba will restrict that access. This includes read access. Without read access, you cannot see the file.)
We just want to see what users are owning what files. We will help you fix any problems, but we cannot fly blind. The most common cause of mixed ownership comes from using both windows file share, and using the wdsync utility to copy/move files. The wdsync program uses a different software process running on the mycloud than does the windows file share, and it runs under different user credentials. As such, files created with the wdsync program inherit different ownership and permissions than those created using the windows file share features. This has been a problem in the past, and if you like, I can link you to the thread where it came up.
As for what SSH IS, here is a quick primer.
SSH is a protocol for accessing the hidden command line interface of the mycloud’s linux OS. You have to enable it in the web GUI, then you connect to it using something like PuTTY. For the curious, it stands for (S)ecure(SH)ell. Another term for a command line prompt is a “shell”. SSH uses encryption to assure that your activity with the remote shell is prevented from being eavesdropped on, hence the “secure” part.
Basically, we need you to get access to the command line so we can help you do some actual administration of your system.
