The last days brought me deep to fiddling with Unix in general and ssh
in special.
First I tried to solve login problems with a sdf OpenBSD box I am
invited to access.
Normally sdf boxes run on NetBSD, this special box offered OpenBSD
instead.
My main reason to access it was the working python which I can't acces
with my regular sdf verified account. After a ssh key upgrade the
OpenBSD box was no more accessible from the outside world and ssh from
another box inside the sdf cluster was not possible because only ARPA
members had access to ssh on these machines.
So I tried a lot of tips, tricks and hacks finally ending up with
buying an ARPA membership (it is a one-time fee of 36$ for lifetime
membership) so I can access this box from inside.
This membership bought me aditionally and ironically besides ssh
Python and other scripting languages on the regular NetBSD machines
so the necessity to access the OpenBSD machine on amy cost was gone.
The rules on sdf are sometimes a little strange - a verified
non-ARPA member lacks access to Perl, Python and other scripting but
has access to c-compilers (I compiled a 2048 game listing written for
Linux successfully on both OSs).
So now there is a rabbit hole and the full access to sdf delivers a
lot of possibillities and fun ...
