Hacking through the limitations by iXSystems and get insecure wide links to work on TrueNAS Scale

SMB Symlinks on TrueNAS Scale.md

Take your own risk because wide links is explicitly not supported, may not survive after upgrade, and may conflict with the functionalities of SMB share.

1. Comment out the parameter blacklists:

cd /usr/lib/python3/dist-packages/middlewared
cp smb.py smb.py.bak
nano smb.py

Comment out the xxx links lines: https://github.com/truenas/middleware/blob/c1ef17656d3e4a893a71086db18783bfc05b2460/src/middlewared/middlewared/plugins/smb.py#L1167

2. Restart middlewared

systemctl restart middlewared

3. Add aux parameters: cli to enter CLI interface then, run sharing smb query to get a list of shares. Note the one you want to edit and look at its id. Then, run sharing smb update id Edit aux_params:

  aux_params:'wide links = yes

  follow symlinks = yes'

Tap on F10, close and save. Next, to modify the global options:

service smb update smb_options="allow insecure wide links = yes"
