[sslh 1.21] 'Operation not permitted' error after upgrading from 1.19c to 1.21

[Yasston]

Is this a new Bug?

• I checkd that the bug hasn't been reported before

Package Name

sslh

Package Version

1.21

Device Model

DS916+

Device Architecture

x86_64

Firmware Version

6.2.4-25556 Update 3

What happened?

I've been running sslh package for over 2 years without issue. I just upgraded from 1.19c to 1.21 version and sslh now refuses to start. In the /usr/local/sslh/var/sslh.log I can see this :

Is this something related to the changes that came with DSM 6 and the permissions issues reported here #2904 ?

If so, how come I didn't have any issues before ? Also I need to mention that a DSM automatic update happened on my NAS last weekend, which may or may not have triggered the problem ?

I am available to perform all kinds of troubleshooting steps.

Many thanks for your time and answers

Reproduction steps

1. Upgrade sslh package from 1.19c to 1.21
2. Upgrade is successful
3. Package refuses to start

Found the answer in this issue here : #4676

Changed the user to "sc-sslh" in the sslh.cfg file, restarted from Package manager ui, all OK. Thank you (again) @hgy59
