openssl又被爆出新漏洞(CVE-2016-2107)(升级脚本)OpenSSl 密码库的维护人员发布了一个高危安全漏洞的补丁(CVE-2016-2107),这个漏洞可以让攻击者在web服务器上解密登录证书或者执行恶意代码。当连接使用AES CBC加密并且服务器支持AES-NI的情况下,中间人攻击者可以使用padding oracle攻击来解密流量。填充检测被重写来确保读取的字节总是相同的,并且对MAC和填充字节进行比较。但它不再检查是否有足够的数据来包含MAC和填充字节。影响:高危修复方案:OpenSSL 1.0.2 用户请更新到1.0.2h版本OpenSSL 1.0.1 用户请更新到1.0.1t版本https://www.openssl.org/news/vulnerabilities.html#y2016----------------------------分割线登录SSH上操作wget http://down.wdlinux.cn/in/openssl201605.shsh openssl201605.sh如果能顺利执行完成,不出什么错,就升级完了

Touchscreen This page is a documentation of my dealings with various touchscreen devices I've encountered. In my experience, most modern devices work out of the box with both 10.04 LTS or 12.04 LTS, but lack the proper calibration or configuration. Some older devices, especially those embedded in laptops such as GD Itronix line of rugged computers, use serial interfaces which lack the configuration to work in Linux. The methods documented here should work with other distros as well. Global Dynamics Itronix GoBook XR-1This is a rugged laptop I picked up from ebay for a good price, which the seller wiped with Ubuntu 10.04 due to the expense of Microsoft's Windows relicensing fee. The device has an integrated serial touchscreen, and the manufacturer is notorious for hiding any and all documentation on legacy devices such as this one. With a little trial and error however, it's relatively simple to configure this and similar devices. This method should work for most G...

Rsync+sersync环境:centos 7 or centos 7.1  x64前言:一、为什么要用Rsync+sersync架构?1、sersync是基于Inotify开发的,类似于Inotify-tools的工具2、sersync可以记录下被监听目录中发生变化的(包括增加、删除、修改)具体某一个文件或某一个目录的名字,然后使用rsync同步的时候,只同步发生变化的这个文件或者这个目录。二、Rsync+Inotify-tools与Rsync+sersync这两种架构有什么区别?1、Rsync+Inotify-tools(1):Inotify-tools只能记录下被监听的目录发生了变化(包括增加、删除、修改),并没有把具体是哪个文件或者哪个目录发生了变化记录下来;(2):rsync在同步的时候,并不知道具体是哪个文件或者哪个目录发生了变化,每次都是对整个目录进行同步,当数据量很大时,整个目录同步非常耗时(rsync要对整个目录遍历查找对比文件),因此,效率很低。2、Rsync+sersync(1):sersync可以记录下被监听目录中发生变化的(包括增加、删除、修改)具体某一个文件或某一个目录的名字;(2):rsync在同步的时候,只同步发生变化的这个文件或者这个目录(每次发生变化的数据相对整个同步目录数据来说是很小的,rsync在遍历查找比对文件时,速度很快),因此,效率很...
现实中,服务器可能会因为各种原因而crash掉,从而造成数据丢失或者服务的暂时不可用。为了提高服务的可用性以及数据的安全性,就需要对数据进行备份,以便数据恢复或者服务的动态切换(将访问请求动态重定向到备份服务器)。常见的备份方法是定时的rsync任务或者远程拷贝。但这种方式,如果定时的间隔较大,那么服务器宕掉后,还是会丢失部分数据,动态切换的服务也不是宕机前的最新状态。为了支持实时数据同步,Linux 2.6.13 内核中新引入文件系统变化通知机制inotify,一旦对文件系统有改动,就会触发相关事件任务。通过结合rsync,inotify能够很好地完成实时同步任务。主服务器:1.1.1.1 备份服务器:0.0.0.0配置步骤:1. 主服务器,备份服务器上安装rsync:sudo yum install rsync 2. 主服务器上安装inotify-tools:sudo yum install inotify-tools 3. 备份服务器上添加配置文件/etc/rsyncd.confreadonly=no chroot=no uid=root gid=root hosts allow=1.1.1.1 hosts deny=0.0.0.0/32 max connections=10 log file=/var/log/rsyncd.log pid file=/var/run/rsyncd.pid lock file=/var/run/rsync.lock auth users=tongbu secrets file=/etc/rsync.pass [websit...
