After updating my QNAP TS-251+ server to the latest firmware revision and updating the Network and Virtual Switch manager, I came across a strange error that prevented any access to the network settings at all:
You don’t have permission to access /apps/netmgr/ on this server.
After some investigation I seem to have found the culprit in my case, that the ‘ /mnt/ext/opt/apps/netmgr’ folder is actually a symlink which links to itself, resulting in the error.
If you’re interested in trying my fix, open up an SSH connection and follow along with my commands as follows:
First, we check to see if the issue is actually a bad symlink:
[~] # ls -l /mnt/ext/opt/apps/netmgr lrwxrwxrwx 1 admin administ 19 Dec 30 01:36 /mnt/ext/opt/apps/netmgr -> /mnt/ext/opt/netmgr [~] # ls -l /mnt/ext/opt/netmgr/ lrwxrwxrwx 1 admin administ 19 Dec 30 01:36 /mnt/ext/opt/netmgr -> /mnt/ext/opt/netmgr [~] # ls -l /mnt/ext/opt/netmgr/ ls: /mnt/ext/opt/netmgr/: Too many levels of symbolic links
Next, delete them
[~] # rm /mnt/ext/opt/netmgr [~] # rm /mnt/ext/opt/apps/netmgr
And finally, replace it with our own symlink to the proper location.
[~] # ln -s /share/CACHEDEV1_DATA/.qpkg/netmgr /mnt/ext/opt/apps/netmgr [~] # ln -s /share/CACHEDEV1_DATA/.qpkg/netmgr /mnt/ext/opt/netmgr
I’m still having issues getting the latest beta netmgr to work, but I will update this if I make any progress.
Eventually I found a file that will manually run the netmgr installation via the command line. I had to run it twice, but in the end it finally was fixed!
