Here's the thing: I have two applications, written in C++ and running on two machines with different OS (one Linux and one Windows). One of this process is in charge of updating an XML file on a NAS (Network Attached Storage) while the other one reads this file. Is it possible to synchronize these two processes in order to avoid reading of the file at the same time it's being modified? You could create a lock file on the server that is created before you do a write, wait then write and delete on completion., Have the read process check for the token before reading the file. Edit : To address

方案前文: 建立一个家庭私有云盘方案系列教程+N2n+Nextcloud 上一篇: 家庭私有云盘系列教程-本地搭建家庭NAS方案 上文已经提到在公网上创建N2N中心节点及客户端节点,这里也不再提起。 作为后续内容,这将说明下在公网服务器使用Nginx转发tcp流量到内网上。 安装Nginx #安装编译支持库 mkdir /mnt/tools -p cd /mnt/tools yum -y install gcc automake autoconf libtool make yum install gcc gcc-c++ #安装PCRE wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.40.tar.gz tar -xzf pcre-8.40.tar.gz -C ./ cd pcre-8.40 ./configure --prefix=/usr/local/pcre make && make install cd .. #安装zlib wget http://zlib.net/zlib-1.2.11.tar.gz tar -xzf zlib-1.2.11.tar.gz -C ./ cd zlib-1.2.11 ./configure --prefix=/usr/local/zlib make &&

Nas 系统的虚拟化方案

Nas 系统的虚拟化方案 https://zhuanlan.zhihu.com/p/55025102 对搞技术的人来说,Nas 是个理想的玩具,既然是程序员用的 Nas ,自然要专业一点,不能像小白一样买台威联通或者群晖往哪里一放就行,如果这样,就没有必要继续往下读了。 就像有人喜欢买成品车,有人喜欢自己改装车;有人喜欢傻瓜相机,有人喜欢机械相机。如果你喜欢 DIY,想让自己家里的硬件发挥更大用途,让自己的 nas 系统更专业些,那么请继续。 有人说,生命的意义在于奉献;还有人说,生命的意义在于付出;然而对于 Nas 玩家来说,生命的意义只有两个字 -- “折腾”。 有人问:“Nas 还能玩出一朵花来?”,答案是:“当然能”,折腾 Nas 第一步就是上虚拟化环境,有这个基础,后面才能更好的搞其他东西。所以今天我们先把 Nas 虚拟化这个纲领性的问题给说清楚说透彻。 Nas 系统为什么要虚拟化? 首先是让一台物理机可以安装多个不同的隔离的操作系统,Nas 很多都是魔改 Linux,一机多用的话,除了可以自由的安装其他主流 Linux 发行版外,你还能装台 Windows 来跑迅雷。 其次,而对于程序员,往往还需要另外一个干净的标准 Linux 发行版作为一个开发/折腾的环境,比如 Ubuntu / Debian / Centos 这些,虚拟化后,你可以自由的折腾你的发行版

How do I fix the error below? Your PHP installation appears to be missing the MySQL extension which is required by WordPress. I use my NAS with a telnet connection.

Python referencing old SSL version

I have a Dropbox upload script on an old nas box I have, recently I've been getting the following error SSL certificate error: [Errno 1] _ssl.c:504: error:0D0890A1:asn1 encoding routines:ASN1_verify:unknown message digest algorithm I think this is due to openssl being out of date on the box So I download openssl, built it from source and installed it, now when I run the following it appears to be updated correctly. openssl version OpenSSL 1.0.1h 5 Jun 2014 But it would appear Python is still referencing an old version, how would I update this? python -c "import ssl; print ssl.OPENSSL_VERSION"
