最近因为绿盟扫描到AIX5.3 AIX6.1系统有openssh高危漏洞，OPENSSH6.4之前的都报高危漏洞，IBM官网上也只有最新的openssh6.0安装文件供下载，没办法只有自己试验的用源码来安装升级，期间各种报错，搞了差不多一周的时间，才顺利的安装的把openssh版本升上去了。以下是安装步骤
1，修改/etc/profile文件
cp -p /etc/profile /etc/profile_bak
/etc/profile文件添加
export LIBPATH=/opt/freeware/lib
export PATH=$PATH:/usr/local/bin:/usr/local/sbin
source /etc/profile
2，安装openssl1.0.1g
从http://www-frec.bull.com/recherche.php下载所需的opensslRPM安装包，并安装：
openssl-1.0.1g-1.aix6.1.ppc.rpm
openssl-devel-1.0.1g-1.aix6.1.ppc.rpm
root@SHDNSDB02:/home/weihu>rpm -Uvh openssl-1.0.1g-1.aix6.1.ppc.rpm
warning: /var/ssl/openssl.cnf saved as /var/ssl/openssl.cnf.rpmorig

root@SHDNSDB02:/home/weihu>rpm -Uvh openssl-devel-1.0.1g-1.aix6.1.ppc.rpm

接下来需要安装zlib，由于没有安装GCC，需要首先安装GCC
从http://www-frec.bull.com/recherche.php下载GCC RPM包，并下载相关的倚赖安装包，并安装：
2503gcc-cpp-4.8.1-2.aix6.1.ppc.rpm-with-deps.zip
gcc-4.8.1-2.aix6.1.ppc.rpm
首先将2503gcc-cpp-4.8.1-2.aix6.1.ppc.rpm-with-deps.zip解压出来

root@SHDNSDB02:/home/weihu>type gcc
gcc is /usr/bin/gcc
到此GCC已经安装好。
接下来编译zlib,我用的zlib版本是zlib-1.2.5.tar.bz2，解压并编译它
(*注意这里一定要安装，否则会报错：configure: error: *** zlib.h missing - please install first or check config.log ****)
root@SHDNSDB02:/home/weihu>bzip2 -d zlib-1.2.5.tar.bz2
root@SHDNSDB02:/home/weihu>tar -xvf zlib-1.2.5.tar
root@SHDNSDB02:/home/weihu>cd zlib-1.2.5
root@SHDNSDB02:/home/weihu>./configure
root@SHDNSDB02:/home/weihu>make
root@SHDNSDB02:/home/weihu>make install
编译openssh,并将openssh源码包打包成
root@SHDNSDB02:/home/weihu>gzip -d openssh-6.6p1.tar.gz
root@SHDNSDB02:/home/weihu>tar xvf openssh-6.6p1.tar
root@SHDNSDB02:/home/weihu>cd openssh-6.6p1
root@SHDNSDB02:/home/weihu>./configure
root@SHDNSDB02:/home/weihu/openssh-6.6p1>contrib/aix/buildbff.sh (*这条命令生成BFF格式可安装文件，如果脚本最后没有生成openssh-6.6p1.bff文件，你需要检查LIB_ PATH是否设置好，并且source /etc/profile让设置立即生效，同时需要make clean清空上次configure的文件，然后再次./configure并执行buildbff.sh文件*)
root@SHDNSDB02:/home/weihu/openssh-6.6p1>ls -lat openssh
openssh-6.6p1.bff openssh.xml opensshd.init
openssh-exec(): openssh.xml.in opensshd.init.in
root@SHDNSDB02:/home/weihu/openssh-6.6p1>ls -lat openssh-6.6p1.bff
-rw-r--r-- 1 root system 4966400 Oct 16 16:17 openssh-6.6p1.bff
在当前目录下安装openssh-6.6p1.bff文件
root@SHDNSDB02:/home/weihu/openssh-6.6p1>inutoc .
(*注意运行上面的命令出现此错误sh: 0403-057 Syntax error at line 1 : `(‘ is not expected.，只需要删除当前目录下的openssh-exec(): 文件即可正常运行*)
root@SHDNSDB02:/home/weihu/openssh-6.6p1>installp -acgNQqX -d . -f .toc
到此OPENSSH安装成功
这个时候看ssh版本还是以前的
root@SHDNSDB02:/>type sshd
sshd is /usr/sbin/sshd
关闭sshd
root@SHDNSDB02:/>stopsrc -s sshd
备份老版本sshd，建立软链接到新版本
root@SHDNSDB02:/>mv /usr/sbin/sshd /usr/sbin/sshd_bak
root@SHDNSDB02:/>ln -s /usr/local/sbin/sshd /usr/sbin/sshd
启动ssh
root@SHDNSDB02:/>/usr/sbin/sshd
Could not load host key: /usr/local/etc/ssh_host_rsa_key
Could not load host key: /usr/local/etc/ssh_host_dsa_key
Could not load host key: /usr/local/etc/ssh_host_ecdsa_key
Could not load host key: /usr/local/etc/ssh_host_ed25519_key
建立KEY文件
root@SHDNSDB02:/>/usr/local/bin/ssh-keygen -t rsa -f /usr/local/etc/ssh_host_rsa_key
root@SHDNSDB02:/>/usr/local/bin/ssh-keygen -t dsa -f /usr/local/etc/ssh_host_dsa_key
root@SHDNSDB02:/>/usr/local/bin/ssh-keygen -t ecdsa -f /usr/local/etc/ssh_host_ecdsa_key
root@SHDNSDB02:/>/usr/local/bin/ssh-keygen -t ed25519 -f /usr/local/etc/ssh_host_ed25519_key
重新开启ssh服务
root@SHDNSDB02:/>/usr/sbin/sshd
至此ssh服务启动完成，可以正常远程连接
查看以下ssh服务进程和OPENSSH的版本
root@SHDNSDB02:/>ps -ef|grep sshd
weihu 44957866 5767496 0 14:38:48 - 0:00 /usr/sbin/sftp-server -m /etc/ssh/sshd_config

root 7340288 1 0 13:09:44 - 0:00 sshd: weihu [priv]
root 7406052 1 0 16:58:54 - 0:00 /usr/sbin/sshd
root@SHDNSDB02:/>sshd -v
unknown option -- v
OpenSSH_6.6p1, OpenSSL 1.0.1g 7 Apr 2014

[-E log_file] [-f config_file] [-g login_grace_time]
[-h host_key_file] [-k key_gen_time] [-o option] [-p port]
[-u len]
做到这一步openssh的版本就算是升上去了，但是有一个问题还未解决
root@SHDNSDB02:/>stopsrc -s sshd
root@SHDNSDB02:/>startsrc -s sshd
上面的命令无法对ssh进程产生重启和关闭的作用，而且当我重启系统后，ssh是不会自启动的，还好开启了telnet，这个问题暂时还未解决，希望看到此文的网络大牛们给指导指导。
