ubuntu的基本环境的初始化

基本环境的配置

apt install -g openssh-server vim


SSH服务器发送了一个意外的数据包

解决方案1：改用XSHELL 6来连接就行了

解决方案2：改sshd的配置文件，让它向下兼容

①在/etc/ssh/sshd_config配置文件最后面添加下面一行：

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


源的配置

#scp -rp /etc/apt/sources.list /etc/apt/sources.list.bak
#sudo vim /etc/apt/sources.list
