Thanks Manuel, supscan is working, but sup from client does not.
After setting the whole stuff in debug mode, I saw

More precisely, I second what Tim says about the "anon" account which is
mentionned absolutely nowher, neither the manpages, nor various docs
across a Google search.
In fact a query "NetBSD+anon+user" directed me right to this PR.
An for the manpages :
[root@arnor man]# grep -w -r anon man*
man1/sup.1:.B anon
man1/sup.1:.B anon
... dozens of matches concernig UVM ...
and that's all.
Creating the account is not enought : it must be activated...
Which rights are granted to him ? How to close the security hole it
opens ?
Thanks for clarification and help
