Trying to connect = results in a SSH kex error.

[OK9UWU]

So I've got an RB711 with ROS 6.49.18 installed (tried on ROS7, same error), but whenever I try to connect to it, I get this error code.

[2025/05/02 14:41:00.987075, 1] ssh_kex_select_methods: kex error : no match for method mac algo client->server: server [hmac-sha1,hmac-md5], client [hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,hmac-sha2-256,hmac-sha2-512]

Any advice?

Try adding

Host *
    MACs +hmac-sha1

to user config ~/.ssh/config or system-wide config /etc/ssh/ssh_config.
You can replace * with RB711's host/IP address.
