I've been using paramiko for a while and everything has worked as expected, but when I moved out of my testing environment, I got this error when opening an ssh session
paramiko.ssh_exception.SSHException: Incompatible ssh server (no acceptable macs) After tracing down the error, I noticed that on my remote server, I'm missing some entries in my /etc/ssh/sshd_config file. Neither of my setups have these MACs listed:
- HMAC-SHA1
- HMAC-MD5
- HMAC-SHA1-96
- HMAC-MD5-96
However, it works in one and not the other. What could be causing this? I don't have rsa keys saved in either one (remote server does not allow for writing).
