For testing purposes I added a new user to the system and noticed, that this user can not access remote network destination.
[test@Sailfish ~]$ curl -I https://www.github.com curl: (6) Could not resolve host: www.github.com [test@Sailfish ~]$ nslookup www.github.com net.c:156: socket() failed: Permission denied net.c:156: socket() failed: Permission denied (null): can't find either v4 or v6 networking
Looking at all local accounts, it seems that only root, nemo/defaultuser, inet and net_raw have this ability.
What controls such network access and where could I extend the list of users that have access…? Thanks!
