I have the latest version of Ubuntu 20.04 and I am not able to connect via SSH to my GL-B1300’s anymore because the firmware only supports SHA1 as the hash for the DH key exchange which has been deprecated in the latest operating systems as it is considered to be insecure. I dug a little into this and found that dropbear buidls from 2016 supported SHA256 but my routers with the latest firmware all seem to be stuck on dropbear 2015.67-1, i.e. a 5 year old version. Is there a way to remove SHA1 and use SHA256 as I would like my router to have the most up to date security?
Are there any plans afoot to upgrade the firmware such that I can ssh to my router again? I assume if Ubuntu have done this, other versions of Linux and Windows cannot be far behind.
