openssh升级到6.2p2

yum -y install  pam-devel openssl-devel

安装zlib

tar zlib-1.2.8.tar.gz

cd zlib-1.2.8

./configure --shared

make && make install

远程升级可以安装dropbear 替代openssh,防止丢失ssh连接,dropbear默认使用22端口,启动dropbear前 修改openssh的默认端口,或者启动加 -p 端口

下载地址:https://matt.ucc.asn.au/dropbear/releases/

(dropbear兼容性不好,我升级的redhat7.3只能使用dropbear-0.40,大家自己试试,make出错)

tar jxf dropbear-0.40.tar.bz2

./configure  --prefix=/usr/local/dropbear/sbin/dropbear

make && make install

mkdir /etc/dropbear

/usr/local/dropbear/bin/dropbearkey -t dss -f /etc/dropbear/dropbear_dss_host_key

/usr/local/dropbear/bin/dropbearkey -t rsa -s 4096 -f /etc/dropbear/dropbear_rsa_host_key

启动dropbear

/usr/local/dropbear/sbin/dropbear (-p 端口)

tar zxf openssh-6.2p2.tar.gz

cd openssh-6.2p2

./configure --prefix=/usr --sysconfdir=/etc/ssh \

--with-pam --with-zlib --with-md5-passwords

rpm -qa | grep openssh

openssh-server×

openssh-×

rpm -e --nodeps openssh-×

rpm -e --nodeps openssh-server-×

mv /etc/ssh /etc/ssh.bak

mv /usr/bin/ssh /usr/bin/ssh.bak

make && make install

cp  contrib/redhat/sshd.init /etc/rc.d/inin.d/sshd

chmod +x /etc/rc.d/inin.d/sshd

chkconfig  --add sshd

不要断开ssh,启动新安装openssh

修改ssh端口,启动openssh

/etc/rc.d/init.d/sshd start

查看当前ssh版本
