yum install telnet-server
vi /etc/xinetd.d/telnet 
#默认telnet禁用root账户登陆，修改telnet配置文件，将配置文件中的disable         = no<修改为yes
 
vi /etc/securetty
 
#增加
#pts/0
#pts/1
#pts/2
#如果登录用户较多，需要更多的pts/*
 
/etc/init.d/xinetd start #启动xinetd进程。

yum install -y gcc openssl-devel pam-devel rpm-build pam-devel 
wget http://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.7p1.tar.gz
rpm -e `rpm -qa | grep openssh` --nodeps
tar -zxvf openssh-7.7p1.tar.gz 
cd openssh-7.7p1
./configure --prefix=/usr --sysconfdir=/etc/ssh --with-pam --with-zlib --with-md5-passwords --with-tcp-wrappers
make && make install
 
vi /etc/ssh/sshd_config
#sed -i '/^#PermitRootLogin/s/#PermitRootLogin yes/PermitRootLogin yes/' /etc/ssh/sshd_config
#或手动修改PermitRootLogin no 修改为 PermitRootLogin yes 允许root远程登陆
 
service sshd restart 
#重启openssh
ssh -V
#查看版本
 
cp contrib/redhat/sshd.init /etc/init.d/sshd
chkconfig --add sshd
chkconfig sshd on
service sshd start
service sshd restart
chkconfig --list sshd

/etc/init.d/xinetd stop && vi /etc/xinetd.d/telnet
将之前改过的disable=yes又改回去成no.
随后再将修改iptables将23端口关闭,并重启iptables服务.
至此,可以再开ssh登录,用ssh -V查看版本号.
