Unable to negotiate with xxx.xxx.xxx.xxx port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha1

[root@zscp1 ~]# cat /root/.ssh/config
Host *
KexAlgorithms +diffie-hellman-group1-sha1
Ciphers +aes128-cbc

原因是Terminal找不到支持的密钥交换方法，因为新版Openssh中认为SHA1这种hash散列算法过于薄弱，已经不再支持，所以我们需要手动去允许对于SHA1的支持 

支持算法  Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc
