Legacy MACs and Ciphers: Why?
..., and legacy Ciphers (anything in cbc-mode, arcfour*(?)) enabled by default? My proposal would be to change the defaults for ssh_config and sshd_config to contain: MACs hmac-sha2-256,hmac-sha2-512,hmac-sha1 Ciphers aes128-ctr,aes192-ctr,aes256-ctr ...removing md5, truncated versions of sha1, umac64 (for which I can find barely any review), any cipher in cbc mode and other non-mainstream algorithms. Additionally, why does ssh_config prefer hmac-md5 over less broken algorithms? Even if the above reduction of attack surface were not to happen, ssh_config could be changed such that the client p...

OpenSSH performance with VIA padlock
Hello list, please spend a minute considering these facts and maybe there is something to improve: 1) VIA Eden based board can write AES256 encrypted information on HDD at > 60MB/s 2) iperf shows NIC speed 69MB/s 3) openssl tests have even better results 4) openssh can transfer AES256 encrypted information at < 27MB/s (and worse with HDD encryption) It is better with openssh 5.x, than
