Resolution Date 2021-04-19

We disabled some deprecated, less secure ssh key exchange algorithms on the ssh server shipped by the Exasol installation. The following key exchange algorithms were disabled:

  • diffie-hellman-group-exchange-sha1
  • diffie-hellman-group1-sha1

We do not expect any compatibility problems from this change if modern ssh clients are used.
