環(huán)境：

ssh secure shell client3.2.9 + PC win10 + 遠(yuǎn)程主機(jī)Linux Ubuntu4.4.0

如題：新建連接之后彈出server responded “Algorithm negotiation failes”錯(cuò)誤

解決：

在Linux主機(jī)上編輯sshd_config，執(zhí)行命令

sudo vi /etc/ssh/sshd_config

在配置文件末尾添加

Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc

MACs hmac-md5,hmac-sha1,umac-64@openssh.com,hmac-ripemd160,hmac-sha1-96,hmac-md5-96

KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group1-sha1,curve25519-sha256@libssh.org

重啟sshd服務(wù)

sudo? etc/init.d/ssh restart

連接正常

報(bào)錯(cuò)原因：ssh升級后，為了安全，默認(rèn)不再采用原來一些加密算法，需要手工添加進(jìn)去
