Today I got again problem with PHP 7 running despite I have disabled php7.0 apache module: phpinfo was showing php 7 using fastCGI ...
... So if after you follow the below instructions you face this situation, you may need to disable the proxy_fcgi apache module:

sudo a2dismod proxy_fcgi proxy; sudo service apache2 restart

1. Re-Install PHP 5.6

What worked for me was this guide: http://www.lornajane.net/posts/2016/php-7-0-and-5-6-on-ubuntu

Actually is not required to remove php7.0, you can install php5.6 together ( also because you will have dependency problem with phpmyadmin package that required php7.0)

Remove all the stock php packages

List installed php packages with dpkg -l | grep php| awk '{print $2}' |tr "\n" " " then remove unneeded packages with sudo aptitude purge your_packages_here or if you want to directly remove them all use :

sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`

Add the PPA

sudo add-apt-repository ppa:ondrej/php

Install your PHP Version

sudo apt-get update
sudo apt-get install php5.6

You can install php5.6 modules too for example

One of the changes introduced in Ubuntu Wily Werewolf is persistent stateless names. It means your network interfaces in ifconfig output will no longer follow the ethX pattern. This solves major problems with predictability of an interface name on Ubuntu if you have multiple cards. This applies to ethernet, WLAN and WWAN interfaces.

This originally started off due to Dell devices and SLES has defaulted to the nomenclature earlier. It’s nice to see Ubuntu adopting the same too. Both udev and systemd are involved in this change.

The udev naming convention follows different schemes:

  1. Names incorporating Firmware/BIOS provided index numbers for on-board devices (example: eno1)
  2. Names incorporating Firmware/BIOS provided PCI Express hotplug slot index numbers (example: ens1)
  3. Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0)
  4. Names incorporating the interfaces’s MAC address (example: enx78e7d1ea46da)
  5. Classic, unpredictable kernel-native ethX naming (example: eth0) – depreciated

systemd naming convention will use the same convention from above in the below order:

  1. if that information from the firmware is applicable and available
  2. if that information from the firmware is applicable and available
  3. if applicable
  4. in all other cases
  5. is not used by default, but is available if the user chooses so

It’s unlikely this will bother you. However, if you want to fallback to the older nomenclature, you need to make some changes in udev:

Edit /etc/default/grub with your favourite editor, e.g. nano:

sudo nano /etc/default/grub

Find this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change it to:

GRUB_CMDLINE_LINUX_DEFAULT="text"

Update GRUB:

sudo update-grub

For systems that use systemd

This is an additional step for systemd releases, e.g. Ubuntu 15.04, the steps above for grub are still necessary.

說到 Log 分析大家都會先想到用 AWStats 來分析,沒錯這絕對是一個最好的解決方式,但如果你只是要簡單的分析一些資訊,就可以利用一些簡單的 shell 組合來撈出你要的資料

這篇主要是針對 Apache 的 access log 來進行分析,並提供以下範例給大家參考

取得前十名 access 最多的 IP 位址

Linux 底下很方便使用的網路設定管理工具 Network Manager, 具備圖形化的操作介面.

沒有圖形化介面的使用者, 可以使用 nmcli 來設定你的網路連線 .

Usage: nmcli [OPTIONS] OBJECT { COMMAND | help }

在Linux中用xl2tpd建立L2TP协议的VPN连接需要两个配置文件,一个是给xl2tpd的配置文件,一个是给pppd的配置文件(xl2tpd会调用pppd)。

    为说明方便,我们假设我们要建立的VPN连接的名字为testvpn,连到的l2tp服务器地址为xxx.xxx.xxx.xxx,用户名为someone,密码为passwordstring。那么该xl2tpd的配置文件应该如下所示:

在 Windows XP 的命令列輸入任何指令的回應, 預設都會是英文語系, 當你的系統換成 Windows 7 或以上系統時, 假設你的預設語言是繁體中文, 則你執行程式的回應就會是中文.

看起來沒有甚麼問題,  但實際上當你寫了一隻測試程式是根據指令回應的字串做判斷時, 就會產生問題.

以 ping www.hinet.net 來說, 你會去抓 Received = 4 或其它值,

當回應字串為中文時, 就會變成 "收到 =4 "

看起來很便利, 但是會搞死人...

To configure passive mode for vsftpd you need to set some parameters in vsftpd.conf.

pasv_enable=Yes
pasv_max_port=10100
pasv_min_port=10090

This enables passive mode and restricts it to using the eleven ports for data connections. This is useful as you need to open these ports on your firewall.
iptables -I INPUT -p tcp --destination-port 10090:10100 -j ACCEPT

If after testing this all works then save the state of your firewall with

service iptables save

which will update the /etc/sysconfig/iptables file.

To do this is CentOS 7 you have to use the new firewalld, not iptables:

適用對象 :

  • 不小心對 3dp 產生好奇心的人
  • 想了解 3dp 原理的人
  • 擔心這個又擔心那個 , 想要最好 , 但卻不行動的人
  • 有耐心的人 因為文太長 XD

我目前也只是一個剛玩沒多久的新手

因為好奇所以跟社團直接購買了一個 prusa i3 的套件 , 省掉一些找料上的時間損失
我的裝機經驗只有 prusa i3 但目前大多數的 3dp 概念都跟 prusa i3 差不多

她從小左眼幾乎全盲,右眼一使用過度,就容易暈眩、昏倒;她不能開車、走路容易撞牆,做任何事情都比別人吃力,連剪指甲都會剪到手!

除此之外,從小就很窮(曾經住在廁所般大的破房子裡)、自卑、自閉、內向、又笨、又口拙、畏懼上台、外表不起眼、臉上有『北斗七星』、個性又很悶…

常被家人和同學嘲笑是笨蛋,連父母都說:『從沒看過這麼笨的小孩!根本是個二愣子!』從小注定是連父母都不看好的『人生失敗組』!

大學延畢唸了五年,五年來都在跟朋友、同學調頭寸,窮到天天被錢追著跑,為了借錢看盡臉色,是標準的『月光光、心慌慌、苦哈哈』借錢姊!

大學畢業之後,不但找不到工作,還背了60幾萬的學貸,被笑說恐怕要到老了才還得完!她從此認清,命中注定『窮得只剩下自己可以靠』!
