L.S. After upgrading to F36 I have problems accessing the F36 server with ssh form OpenVMS machines. The problem is probably (again) that OpenVMS only supports "old" keys. In the past I added the following to my sshd_config: Ciphers +aes128-cbc MACs umac-64-etm@openssh.com,umac-128-etm@openssh.com,hmac-sha2-256-etm(a)openssh. com,hmac-sha2-512-etm@openssh.com,umac-64@openssh.com,umac-128(a)openssh.com,hmac- sha2-256,hmac-sha2-512,hmac-md5,hmac-md5-96,hmac-sha1,hmac-sha1-96 KexAlgorithms curve25519-sha256(a)libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384 ,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group-ex change-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 This worked in F35. Probably some encryptions are disabled. How can I enable them again? Regards Jouk Pax, vel iniusta, utilior est quam iustissimum bellum. (free after Marcus Tullius Cicero (106 b.Chr.-46 b.Chr.)
