具体操作是这样，我在
vi /etc/network/interfaces 添加静态ip之后，
auto lo
iface lo inet loopback
auto eno1
iface eno1 inet static
address 192.168.0.174
netmask 255.255.255.0
gateway 192.168.0.1
nameservers 8.8.8.8
sudo /etc/init.d/networking restart
之后又重启了
ssh的时候就出现了以下情况
ssh [email protected]
The authenticity of host '192.168.0.174 (192.168.0.174)' can't be established.
ECDSA key fingerprint is SHA256:XQIbi6qISHKG+3CwH4GxO5/XgWsD2bUK+ygTJqEAsvE.
Are you sure you want to continue connecting (yes/no)? yes
输入密码提示密码不正确
ssh -o StrictHostKeyChecking=no [email protected]
输入密码
再次ssh，正常输入密码，问题解决。
