SecureCRT连接服务器时报错,报错信息为:
Key exchange failed. No compatible key exchange method. The server supports these methods: curve25519-sha256,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256
1、原因分析
错误原因是SecureCRT 7.0客户端支持的和kali作为ssh服务端支持的SSH秘钥交换算法不匹配。
Secure CRT 7.0的默认支持key exchange算法:
2、解决方法有以下两种
vi /etc/ssh/sshd_config
#加入下面的文本
KexAlgorithms curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1
#重启ssh
systemctl restart sshd.service
