I get this error when using rsync:
$ rsync -av server:file . Unable to negotiate with 10.1.1.50 port 22: no matching host key type found. Their offer: ssh-dss rsync: connection unexpectedly closed (0 bytes received so far) [Receiver] rsync error: error in rsync protocol data stream (code 12) at io.c(226) [Receiver=3.1.1]
How to fix it?
