About ClamAV From:  Clamav.net ClamAV is an open source (GPL) antivirus engine designed for detecting Trojans, viruses, malware and other malicious threats. It is the de facto standard for mail gateway scanning. It provides a high performance mutli-threaded scanning daemon, command line utilities for on demand file scanning, and an intelligent tool for automatic signature updates. The core ClamAV library provides numerous file format detection mechanisms, file unpacking support, archive support, and multiple signature languages for detecting threats. The core ClamAV library is utilized in Immunet 3.0, powered by ClamAV, which is a fast, fully featured Desktop AV solution for Windows. In Qmailtoaster, ClamAV works side-by-side with SpamAssassin under Simscan to make sure all incoming email is free of virus and spam. Disable / Enable You can disable (and enable it again) ClamAV per domain or server-wide, make sure you know what you are doing and have a strong reason. Per Dom

CentOS-7  CentOS 7 default to  firewalld. It's not recommended to install iptables, please use firewalld yum install iptables system-config-firewall-tui setuptool firewalld default XML directory /usr/lib/firewalld and /etc/firewalld   ===================================================== firewalld  ========== >>> firewall-config ====> firewall-cmd <==== 在firewalld裡面, 是把網路分成幾個區域 (zone). 然後針對zone去設定過濾規則. 我們先看預設設定: [root@c7 ~]# firewall-cmd --get-active-zones public   interfaces: eth0 eth1 所以目前兩個網卡都是被指定在public(對外區域). 然後看看預設public區域的規則: [root@c7 ~]# firewall-cmd --zone=public --list-all public (default, active)   interfaces: eth0 eth1   sources:   services: dhcpv6-client ssh   ports:   masquerade: no   forward-ports:   icmp-blocks:   rich rules: 所以public zone開了DHCP跟SSH服務, 沒有指定port, 沒有限制連線來源, 也沒有開啟NAT功能. DHCP我沒有在用, 所以移掉: [root@c7 ~]# firewall-cmd --zone=public --remove-service dhcpv6-client success 因為eth0是內網, 所以我想把eth0改到trusted(信任區域): [root@

SSH login without password Your aim You want to use Linux and OpenSSH to automate your tasks. Therefore you need an  automatic  login from host A / user a to Host B / user b. You don't want to enter any passwords, because you want to call  ssh  from a within a shell script. How to do it First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase: a@A:~> ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/a/.ssh/id_rsa): Created directory '/home/a/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/a/.ssh/id_rsa. Your public key has been saved in /home/a/.ssh/id_rsa.pub. The key fingerprint is: 3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A Now use  ssh  to create a directory  ~/.ssh  as user b on B. (The directory may already exist, which is fine): a@A:~> ssh b@B mkdir -p .ssh b@B's pass

Advance Tip for VIM 7.X  multi-window ======================================= 1. open gvim with multiple windows.     vim -p file1 file2  Open all files in Tab under current directory at once    vi -p ./*.php 2. switch between tabs with :tabn and :tabp    switch between tabs with <gt>go next tab  and <gT> go prev Tab 3. goto Tab2 <2gt> 4. or assign tab function to function key F7 and F8 5.
