This would be best suited but i didn´t realize that OpenVPN-2.4x do not
accept 1024 bit anymore. All testers seems to oversee this too and the
OpenVPN change log didn´t pointed it out clearly...

Started to make a $problemmessage section where we can put also some
other potential or real problems like e.g. check for 'no MD5 for
signature anymore', 'Soon needed RFC3280 compliance for the
certificates' . There is surely more...
Good idea ?

Should be like above written displayed then above the main settings
section like $errormessage.

Except a little longer time for the handshake the clients won´t realize
this since the DH-parameter takes only place on server side.

Should we do an automatic DH generation of 2k via update.sh with the
next update ?

Best,
