Hi all,
Today I upgraded one of my machine from F21 to F22. After the upgrade I
cannot connect anymore to this machine using my OpenVMS system by means of
ssh. Looks like there is an cipher mismatch. How can I configre my sshd on
F22 to make it work again? (see logs for F22 & F21 below)
On the OpenVMS machine I see:
gigue-jj) ssh -v foxtrot
