升级SSH ssh，

wget http://www.ctohome.com/linux-vps-pack/webmin/upgrade-openssh.sh;sh upgrade-openssh.sh;

 

升级成功后会自动重启ssh服务，效果图如下：

 ==========      SSH Version    ============
OpenSSH_5.5p1, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008


[root@225845 ~]# ssh -V
OpenSSH_5.5p1, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

如果你发现还是ssh4.x版本，而且提示有错误：

openssh-clients-5.5p1-24.el5.i386 from centalt has depsolving problems
  --> Missing Dependency: libedit.so.0 is needed by package openssh-clients-5.5p1-24.el5.i386 (centalt)
Error: Missing Dependency: libedit.so.0 is needed by package openssh-clients-5.5p1-24.el5.i386 (centalt)
 You could try using --skip-broken to work around the problem

那么，先需要安装libedit0类库，如下：

centos 5.x 32位用如下命令安装

rpm -Uvh ftp://ftp.pbone.net/mirror/atrpms.net/el5-i386/atrpms/stable/libedit0-3.0-1.20090722cvs.el5.i386.rpm

centos 5.x 64位用如下命令安装

rpm -Uvh ftp://ftp.pbone.net/mirror/atrpms.net/el5-x86_64/atrpms/stable/libedit0-3.0-1.20090722cvs.el5.x86_64.rpm
