my ssh journey

WD My Cloud Mirror
ssh root@X.X.X.X
Unable to negotiate with X.X.X.X port 22: no matching host key type found. Their offer: ssh-dss
ssh -oHostKeyAlgorithms=+ssh-dss root@192.168.178.20
Add your host key in to ~/.ssh/config
Host wdnas
HostName 192.168.178.20
HostKeyAlgorithms=+ssh-dss
check if the host key already cached
# Host X.X.X.X not found in /Users/XXX/.ssh/known_hosts
remove the locally cached keys
ssh-keygen -R X.X.X.X
Check if it works.
