Update my PC to Ubuntu 22.04 and while trying to SSH into the Router this error appears…
ssh root@XXX.XXX.XXX.XXX Unable to negotiate with XXX.XXX.XXX.XXX port 22: no matching host key type found. Their offer: ssh-rsa
Seems this is due to SSH using rsa encryption and it now being considered weak, and has been for a while. It seems the Openwrt 19.xx uses an older version of SSH.
Is there any way of updating SSH on the Router?
GL.iNet X750 V4.X beta seems to have disappeared from the Repository, so can’t try that.
I feel that this leaves an attack vector of the router open for possible exploitation. ANy help would be much appreciated.
