linux network无法启动解决

/service network start 报错:Bringing up interface eth0:  Device does not seem to be present, delaying initialization. [FAILED] 

解决办法:ifconfig -a 查看eth0的HWaddr值

打开/etc/sysconfig/network-scripts/ifcfg-eth0 文件

修改为:

 

DEVICE=eth0

BOOTPROTO=static

ONBOOT=yes

IPADDR=你的IP

NETMASK=255.255.255.192

HWADDR=00:16:3E:F2:A0:9C

 

重新启动network服务,得以PING通

Centos L2TP相关错误解决

Centos一键安装L2TP脚本下载

也可以参见:CentOS VPS创建l2tp VPN服务

#bash l2tp.sh 安装完成之后,ipsec verify 验证测试环境。

可以参见:VPNs----手把手教你用Openswan建立linux对linux的IPSecRSA连接

出现几点错误:

The Centos L2TP related error solve

Checking for IPsec support in kernel [FAILED]
Checking that pluto is running [FAILED]

这两个错误可以不管,运行“/etc/init.d/ipsec restart
”之后,重新“ipsec verify
”出现新的错误:

Centos L2TP相关错误解决

解决新的错误,需要在终端运行:

for each in /proc/sys/net/ipv4/conf/*
do
    echo 0 > $each/accept_redirects
    echo 0 > $each/send_redirects
done

继续“ipsec verify”,已知的错误成功解决。

L2TP错误解决成功

如果出现不能访问外网的情况,则补充下启用转发:

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Ecshop随机替换链接问题

这点不得不说很恶心,不尊重用户。

在二次开发一个Ecshop项目,文章页面刷新,无意中发现链接会被随机替换成Ecshop官方链接:"Powered by ECShop",包括网站logo部分的链接也可能会被替换。

追查了一下,最后发现问题出在调用的js文件“/js/common.js”这里,里面有onload的执行代码,具体为:

onload = function()
{
    var link_arr = document.getElementsByTagName(String.fromCharCode(65));
    var link_str;
    var link_text;
    var regg, cc;
    var rmd, rmd_s, rmd_e, link_eorr = 0;
    var e = new Array(97, 98, 99,
                      100, 101, 102, 103, 104, 105, 106, 107, 108, 109,
                      110, 111, 112, 113, 114, 115, 116, 117, 118, 119,
                      120, 121, 122
                      );

  try
  {
    for(var i = 0; i < link_arr.length; i++)
    {
      link_str = link_arr[i].href;
      if (link_str.indexOf(String.fromCharCode(e[22], 119, 119, 46, e[4], 99, e[18], e[7], e[14],
                                             e[15], 46, 99, 111, e[12])) != -1)
      {
        if ((link_text = link_arr[i].innerText) == undefined)
        {
            throw "noIE";
        }
        regg = new RegExp(String.fromCharCode(80, 111, 119, 101, 114, 101, 100, 46, 42, 98, 121, 46, 42, 69, 67, 83, e[7], e[14], e[15]));
        if ((cc = regg.exec(link_text)) != null)
        {
          if (link_arr[i].offsetHeight == 0)
          {
            break;
          }
          link_eorr = 1;
          break;
        }
      }
      else
      {
        link_eorr = link_eorr ? 0 : link_eorr;
        continue;
      }
    }
  } // IE
  catch(exc)
  {
    for(var i = 0; i < link_arr.length; i++)
    {
      link_str = link_arr[i].href;
      if (link_str.indexOf(String.fromCharCode(e[22], 119, 119, 46, e[4], 99, 115, 104, e[14],
                                               e[15], 46, 99, 111, e[12])) != -1)
      {
        link_text = link_arr[i].textContent;
        regg = new RegExp(String.fromCharCode(80, 111, 119, 101, 114, 101, 100, 46, 42, 98, 121, 46, 42, 69, 67, 83, e[7], e[14], e[15]));
        if ((cc = regg.exec(link_text)) != null)
        {
          if (link_arr[i].offsetHeight == 0)
          {
            break;
          }
          link_eorr = 1;
          break;
        }
      }
      else
      {
        link_eorr = link_eorr ? 0 : link_eorr;
        continue;
      }
    }
  } // FF

  try
  {
    rmd = Math.random();
    rmd_s = Math.floor(rmd * 10);
    if (link_eorr != 1)
    {
      rmd_e = i - rmd_s;
      link_arr[rmd_e].href = String.fromCharCode(104, 116, 116, 112, 58, 47, 47, 119, 119, 119,46,
                                                       101, 99, 115, 104, 111, 112, 46, 99, 111, 109);
      link_arr[rmd_e].innerHTML = String.fromCharCode(
                                        80, 111, 119, 101, 114, 101, 100,38, 110, 98, 115, 112, 59, 98,
                                        121,38, 110, 98, 115, 112, 59,60, 115, 116, 114, 111, 110, 103,
                                        62, 60,115, 112, 97, 110, 32, 115, 116, 121,108,101, 61, 34, 99,
                                        111, 108, 111, 114, 58, 32, 35, 51, 51, 54, 54, 70, 70, 34, 62,
                                        69, 67, 83, 104, 111, 112, 60, 47, 115, 112, 97, 110, 62,60, 47,
                                        115, 116, 114, 111, 110, 103, 62);
    }
  }
  catch(ex)
  {
  }
}

大概261行开始。只要有加载这个js文件的页面就会有可能被替换成官方链接。

将这段代码去掉后就不会出现随机替换站内链接的情况了。

鄙视下Ecshop。。开源不能这样开!
