bash is down

[Predrag Punosevac]

This is unrelated. OpenVPN client died on your machine. I just restarted. I
have seen this dying on Jerod's and Dan's machine which have some
funky tweaks but not on anybody's else. I just restarted VPN client and
everything else should work as expected now.

Next time you notice things are slow

ifconfig

you have to see tun0 interface. If you don't su - to the root account and

systemctl start openvpn-client at autonlab

FYI I have patched TLS stack on our OpenVPN (OpenBSD machine) server from
overseas to accommodate problems with TLS version 1.3 on OpenSSL used by
Linux client. OpenBSD server uses
LibreSSL. I don't want to enable legacy TLS version and unsafe chipers for
good reasons. As a matter of fact I am getting into a habit of making
system HIPAA compliant so that becomes my second nature (Artur will
appreciate this).

Cheers,
Predrag

P.S. If anybody's else desktop appears to be slow please let me know and I
will take care next time I am in front of the computer.
