Hello flichtenheld, plaisthos,
I'd like you to reexamine a change. Please visit
http://gerrit.openvpn.net/c/openvpn/+/1145?usp=email
to look at the new patch set (#2).
Change subject: Remove use of 'dh dh2048.pem' from sample configs, remove
'dh2048.pem' file
......................................................................
Remove use of 'dh dh2048.pem' from sample configs, remove 'dh2048.pem' file
Since commit bd9aa06feb41 (Jan 2015) OpenVPN has allowed to use
'--dh none' to disable traditional Diffie Hellman, since more secure
ECDH algorithms are available that do not use explicit DH parameters.
If configured with a suffiently high securelevel (3+), or if running in
FIPS mode, OpenSSL 3.5 will refuse 2048 bit DH files, making our tests
fail.
Thus, remove all the DH2048 stuff from our sample configs.
Github: triggered by OpenVPN/openvpn#819
