SSH/SSL 源码编译安装简易操作说明-服务器评测

安全加固需求，由于某盟扫描系统主机有SSL系列漏洞，客户要求必须修复；
解决方案：将SSH/SSL升级到最新版本，删除SSL旧版本（实测不删除旧版本某盟扫描无法通过）。
当前版本：OpenSSH_5.3p1, OpenSSL 1.0.1e-fips
当前最新版本：OpenSSH_7.3p1, OpenSSL 1.0.2h

1.查看SSH/SSL当前版本
2.下载最新的SSH/SSL
3.源码编译安装SSL
4.源码编译安装SSH
5.删除SSL旧版本
6.写在后面

1.查看SSH/SSL当前版本

查看SSH/SSL当前版本：
ssh -V
openssl version

[root@test0823 ~]# ssh -V
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013

[root@test0823 ssh]# openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013

备份ssh配置文件：
tar zcvf /etc/ssh.tar.gz /etc/ssh/

[root@test0823 ~]# tar zcvf /etc/ssh.tar.gz /etc/ssh/  
ssh/  
ssh/ssh_host_dsa_key.pub  
ssh/ssh_host_rsa_key.pub  
ssh/ssh_host_rsa_key  
ssh/sshd_config  
ssh/ssh_config  
ssh/moduli  
ssh/ssh_host_dsa_key  
ssh/ssh_host_key.pub  
ssh/ssh_host_key

2.下载最新的SSH/SSL

3.源码编译安装SSL

本次测试所有源码包均默认上传到服务器的/root目录下。
需要先安装SSL，再安装SSH

3.1 解压SSL源码包

[root@test0823 ~]# tar -zxvf openssl-1.0.2h.tar.gz 
[root@test0823 ~]# cd openssl-1.0.2h

3.2 配置并编译

复制下面的命令执行：

./config --prefix=/usr         \
         --openssldir=/etc/ssl \
         --libdir=lib          \
         shared                \
         zlib-dynamic &&
make depend           &&
make

操作如下：

[root@test0823 openssl-1.0.2h]# ./config --prefix=/usr         \
>          --openssldir=/etc/ssl \
>          --libdir=lib          \
>          shared                \
>          zlib-dynamic &&
> make depend           &&
> make

3.3 安装SSL

复制下面的命令执行：

make MANDIR=/usr/share/man MANSUFFIX=ssl install &&
install -dv -m755 /usr/share/doc/openssl-1.0.2h  &&
cp -vfr doc/*     /usr/share/doc/openssl-1.0.2h

操作如下：

[root@test0823 openssl-1.0.2h]# make MANDIR=/usr/share/man MANSUFFIX=ssl install &&
> install -dv -m755 /usr/share/doc/openssl-1.0.2h  &&
> cp -vfr doc/*     /usr/share/doc/openssl-1.0.2h

3.4 验证SSL版本

openssl version

操作如下：

[root@test0823 openssl-1.0.2h]# openssl version
OpenSSL 1.0.2h  3 May 2016
[root@test0823 openssl-1.0.2h]# ssh -V
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013

4.源码编译安装SSH

4.1 解压SSH源码包

[root@test0823 ~]# tar -zxvf openssh-7.3p1.tar.gz 
[root@test0823 ~]# cd openssh-7.3p1

4.2 配置

4.2.1 配置前准备

复制下面的命令执行：

install  -v -m700 -d /var/lib/sshd &&
chown    -v root:sys /var/lib/sshd &&

groupadd -g 50 sshd        &&
useradd  -c 'sshd PrivSep' \
         -d /var/lib/sshd  \
         -g sshd           \
         -s /bin/false     \
         -u 50 sshd

操作如下：

[root@test0823 openssh-7.3p1]# install  -v -m700 -d /var/lib/sshd &&
> chown    -v root:sys /var/lib/sshd &&
> 
> groupadd -g 50 sshd        &&
> useradd  -c 'sshd PrivSep' \
>          -d /var/lib/sshd  \
>          -g sshd           \
>          -s /bin/false     \
>          -u 50 sshd

4.2.2 配置并编译

复制下面的命令执行：

./configure --prefix=/usr                     \
            --sysconfdir=/etc/ssh             \
            --with-md5-passwords              \
            --with-privsep-path=/var/lib/sshd &&
make

操作如下：

[root@test0823 openssh-7.3p1]# ./configure --prefix=/usr                     \
>             --sysconfdir=/etc/ssh             \
>             --with-md5-passwords              \
>             --with-privsep-path=/var/lib/sshd &&
> make

4.3 安装SSH

复制下面的命令执行：

make install &&
install -v -m755    contrib/ssh-copy-id /usr/bin     &&

install -v -m644    contrib/ssh-copy-id.1 \
                    /usr/share/man/man1              &&
install -v -m755 -d /usr/share/doc/openssh-7.3p1     &&
install -v -m644    INSTALL LICENCE OVERVIEW README* \
                    /usr/share/doc/openssh-7.3p1

操作如下：

[root@test0823 openssh-7.3p1]# make install &&
> install -v -m755    contrib/ssh-copy-id /usr/bin     &&
> 
> install -v -m644    contrib/ssh-copy-id.1 \
>                     /usr/share/man/man1              &&
> install -v -m755 -d /usr/share/doc/openssh-7.3p1     &&
> install -v -m644    INSTALL LICENCE OVERVIEW README* \
>                     /usr/share/doc/openssh-7.3p1

4.4 验证SSH版本

[root@test0823 openssh-7.3p1]# ssh -V
OpenSSH_7.3p1, OpenSSL 1.0.2h  3 May 2016

4.5 重启sshd服务

将之前的sshd重命名备份，做一个sshd的软连接：

mv /usr/sbin/sshd /usr/sbin/sshd.OFF
ln -s /root/openssh-7.3p1/sshd /usr/sbin/sshd

使用 service sshd restart 重启一下服务

[root@test0823 openssh-7.3p1]# service sshd restart
Stopping sshd: [  OK  ]
Starting sshd: /etc/ssh/sshd_config line 81: Unsupported option GSSAPIAuthentication
/etc/ssh/sshd_config line 83: Unsupported option GSSAPICleanupCredentials
/etc/ssh/sshd_config line 97: Unsupported option UsePAM
[  OK  ]

上面的报错并不影响sshd正常启动，为了不再显示上述提示，可以注释掉相关配置行：
vi /etc/ssh/sshd_config
注释掉 81，83，97 三行。

再次重启sshd服务就不会有那三行的提示报错。

允许root用户ssh登录（默认可能就是允许，如果不允许，可以在文件末尾追加下面的一行配置到配置文件，或者直接vi编辑修改）

echo "PermitRootLogin yes" >> /etc/ssh/sshd_config

5.删除SSL旧版本

之前没有删除旧版本的SSL,SSH是因为不了解相关联的程序，
但是最后扫描发现如果不删除旧版本的SSL，某盟的扫描依然会扫出SSL的系列漏洞。

查看rpm安装的openssl相关包：

rpm -qa|grep openssl

对旧版本的SSL（这里是openssl-1.0.1e-42.el6.x86_64）进行删除：
rpm -e openssl-1.0.1e-42.el6.x86_64
直接尝试删除会提示如下库文件的依赖：

[root@test0823 ~]# rpm -e openssl-1.0.1e-42.el6.x86_64

记录好依赖的这两个库文件

libcrypto.so.10
libssl.so.10

然后忽略依赖删除：

rpm -e --nodeps openssl-1.0.1e-42.el6.x86_64

做新的软连接映射：

[root@test0823 openssl-1.0.2h]# ln -s /root/openssl-1.0.2h/libssl.so.1.0.0 /usr/lib64/libssl.so.10
[root@test0823 openssl-1.0.2h]# ln -s /root/openssl-1.0.2h/libcrypto.so.1.0.0 /usr/lib64/libcrypto.so.10

如果是最后删除的openssl，那么还需要注意openssl软连接的情况，如下：

[root@test0823 apps]# ln -s /root/openssl-1.0.2h/apps/openssl /usr/bin/openssl

然后再次扫描已经没有SSL相关漏洞了。

SSH/SSL 源码编译安装简易操作说明

3.源码编译安装SSL

本次测试所有源码包均默认上传到服务器的/root目录下。
需要先安装SSL，再安装SSH

3.1 解压SSL源码包

`[root@test0823 ~]# tar -zxvf openssl-1.0.2h.tar.gz [root@test0823 ~]# cd openssl-1.0.2h`

3.4 验证SSL版本

openssl version

操作如下：

`[root@test0823 openssl-1.0.2h]# openssl version OpenSSL 1.0.2h 3 May 2016 [root@test0823 openssl-1.0.2h]# ssh -V OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013`

4.源码编译安装SSH

4.1 解压SSH源码包

`[root@test0823 ~]# tar -zxvf openssh-7.3p1.tar.gz [root@test0823 ~]# cd openssh-7.3p1`

4.2 配置

4.4 验证SSH版本

`[root@test0823 openssh-7.3p1]# ssh -V OpenSSH_7.3p1, OpenSSL 1.0.2h 3 May 2016`
