Linux ssh权限被修改问题修复

测试：/usr/sbin/sshd -T

配置：

sh "chown root:root /etc/sudo.conf -R"

sh "chown -R root:root /etc/sudoers.d"

sh "chown root:root /etc/sudoers"

   sh "chown -R root /usr/libexec/sudo/"

sh "chmod 644 /usr/libexec/sudo/sudoers.so"

   sh "chmod 440 /etc/sudoers.d"

    sh "chmod 4755 /usr/bin/sudo"

    chmod -R 600 /etc/sudo.conf

    chmod -R 600 /etc/sudoers

    chown -R root:root /var/empty/sshd

    chmod -R 711 /var/empty/sshd

    chmod -R 600 /etc/ssh

 

ssh 免密登录：

chmod -R 700 /root/

chmod 600 /root/.ssh/id_dsa

chmod 644 /root/.ssh/authorized_keys /root/.ssh/id_dsa.pub
