SecureCRT--解决Key exchange failed.No compatible key-exchange method
简介
本文介绍SecureCrt连接Linux的报错问题:Key exchange failed.No compatible key-exchange method
问题复现
我在使用SecureCrt连接Linux时,报了如下错误:
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
两种解决方法:
第一种: 升级SecureCRT为最新版,或者使用其他连接工具
第二种: 修改服务器,使其兼容老系统的算法
登录服务器后,在服务器里使用下面命令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
树莓派相同情况
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
