Centos7+Open***使用用户及密码验证登陆
我们上一篇文章介绍了Centos7+Open***使用证书验证登陆介绍,今天我们介绍Centos7+Open***使用用户及密码登陆验证,具体就补多少了,环境还是基于上一篇的更改来完成。
我们使用Centos7+Open***使用用户及密码登陆验证小下载一个验证脚本来完成用户验证登陆。
#!/bin/sh############################################################ checkpsw.sh (C) 2004 Mathias Sundman## This script will authenticate Open××× users against# a plain text file. The passfile should simply contain# one row per user with the username first followed by# one or more space(s) or tab(s) and then the password.PASSFILE="/usr/local/open***/etc/psw-file"LOG_FILE="/usr/local/open***/var/open***-password.log"TIME_STAMP=`date "+%Y-%m-%d %T"`###########################################################if [ ! -r "${PASSFILE}" ]; then echo "${TIME_STAMP}: Could not open password file \"${PASSFILE}\" for reading." >> ${LOG_FILE} exit 1fiCORRECT_PASSWORD=`awk '!/^;/&&!/^#/&&$1=="'${username}'"{print $2;exit}' ${PASSFILE}`if [ "${CORRECT_PASSWORD}" = "" ]; then echo "${TIME_STAMP}: User does not exist: username=\"${username}\", password=\"${password}\"." >> ${LOG_FILE} exit 1fiif [ "${password}" = "${CORRECT_PASSWORD}" ]; then echo "${TIME_STAMP}: Successful authentication: username=\"${username}\"." >> ${LOG_FILE} exit 0fiecho "${TIME_STAMP}: Incorrect password: username=\"${username}\", password=\"${password}\"." >> ${LOG_FILE}exit 1
我们然后进入open***的配置目录
cd /etc/open***/vi checkpsw.sh
然后将脚本文件粘贴,然后需要修改PASSFILE和LOG_FILE的路劲,根据自己的真是路劲修改
保存退出,然后我们需要修改open***的server.conf 文件,然后添加以下配置字段
auth-user-pass-verify /etc/open***/userauthdir/checkpsw.sh via-env 开启用户密码脚本:client-cert-not-required 取消客户端的证书认证:username-as-common-name 不要求客户端有证书script-security 3 system 消除以下警告
我们在修改前先看看上一篇的配置文件内容
我们为了更好的体现配置,将原来的server.conf文件进行过滤注释的内容,然后拷贝出来新建一个server.conf文件,然后将没有注释的内容添加到新建的server.conf文件中这样为了更好的配置和拍错。
我们上一节是在默认的server.conf文件里面直接修改的,所以我们需要将没有注释的内容过滤出来,我们先看看默认的配置文件内容

默认内容比较多,所以我们过滤一下
cat /etc/open***/server.conf | grep "^[^#|^;]"port 1194proto tcpdev tunca ca.crtcert server.crtkey server.key # This file should be kept secretdh dh2048.pemserver 10.10.10.0 255.255.255.0ifconfig-pool-persist ipp.txtpush "route 192.168.5.0 255.255.255.0"push "dhcp-option DNS 223.5.5.5"push "dhcp-option DNS 223.6.6.6"keepalive 10 120max-clients 100user nobodygroup nobodypersist-keypersist-tunstatus open***-status.loglog open***.logverb 5
我们在修改前首先要需要将将原来默认的进行重命名一下作为备份。
mv /etc/open***/server.conf /etc/open***/server.conf.bak2
然后我们在/etc/open***目录下vi server.conf文件,然后将过滤的内容粘贴修改即可
vim server.conflocal 192.168.5.20 #监听地址port 1194 #监听端口proto tcp #监听协议dev tun #采用路由隧道模式ca ca.crt #ca证书路径cert server.crt #服务器证书key server.key # This file should be kept secret 服务器密钥dh dh2048.pem #密钥交换协议文件server 10.8.0.0 255.255.255.0 #给客户端分配地址池,注意:不能和×××服务器内网网段有相同ifconfig-pool-persist ipp.txtpush "route 192.168.6.0 255.255.255.0" #允许客户端访问内网 6.0 的网段。push"dhcp-option DNS 223.5.5.5" #dhcp分配dnsclient-to-client #客户端之间互相通信keepalive 10 120 #存活时间,10秒ping一次,120 如未收到响应则视为断线comp-lzo #传输数据压缩max-clients 100 #最多允许 100 客户端连接user nobody #用户group nobody #用户组persist-keypersist-tunstatus /var/log/open***/open***-status.loglog /var/log/open***/open***.logverb 5
然后我们需要是使用用户和密码验证登陆,所以还需要添加以下语句
auth-user-pass-verify /etc/open***/checkpsw.sh via-envclient-cert-not-required username-as-common-name
我们添加后
port 1194 #监听端口proto tcp #监听协议dev tun #采用隧道ca ca.crt #ca证书路劲cert server.crt #服务器证书路劲key server.key #服务器秘钥dh dh2048.pem #秘钥交换协议文件server 10.10.10.0 255.255.255.0 #给客户端分配的地址,注意:不能和***服务器的内部地址相同ifconfig-pool-persist ipp.txt #访问记录push "route 192.168.5.0 255.255.255.0" #允许客户端访问的地址网段#push "redirect-gateway def1 bypass-dhcp"push "dhcp-option DNS 223.5.5.5" #DHCP分配的DNSpush "dhcp-option DNS 223.6.6.6"keepalive 10 120 #活动时间,10秒ping一次,120秒如果未收到响应视为断线#cipher AES-256-CBCmax-clients 100 #允许最大连接数#user nobody #用户#group nobody #用户组persist-keypersist-tunstatus open***-status.loglog open***.logverb 5client-cert-not-requiredusername-as-common-namescript-security 3auth-user-pass-verify /etc/open***/checkpsw.sh via-env
第三步:新建用户和密码认证文件,psw-file(这里的文件就是server.conf那个文件,注意存放时,路径和配置文件时的一致)
cd /etc/open***/vim psw-filetest123456 (前面是用户 后面是密码)
注:这里 psw-file的权限,尽量小点
chmod 400 psw-filechmod +x checkpsw.sh
修改好后,我们重启open***服务
第四步:修改客户端配置文件:client.conf(或者client.o***)
注销掉这两行
#cert client1.crt#key client1.key
再添加这一行,添加这行,就会提示输入用户名和密码
auth-user-pass
我们为了显示好看及好判断问题,所以我们需要把客户端的配置文件清空,然后编写有用的
clientdev tunproto tcpremote 192.168.5.20 1194resolv-retry infinitenobindpersist-keypersist-tunca ca.crt# cert client.crt#key client.key#remote-cert-tls serververb 5auth-user-pass
保存会,我们单击open***客户端,然后连接,会提示输入账户及密码
最后我们可以查看log确认登陆情况
tail -f /etc/open***/open***.log
tail -f /etc/open***/open***-password.log
