CentOS 7 firewalld and iptables firewall setup allow multicast traffic

CentOS 7 remove firewalld and enable iptables.service

1. 關閉及停止使用 Firewalld:
systemctl status firewalld
systemctl disable firewalld (Loaded: loaded, Active: active)
systemctl mask firewalld (Loaded: masked, Active: active)
systemctl stop firewalld (Loaded: masked, Active: inactive)
sudo reboot -h now

2. 安裝 iptables
yum install iptables-services

3. 啟動及設定開機執行 iptables
systemctl status iptables.service
systemctl enable iptables
systemctl start iptables

現在已經可以用 iptables, 增加及剛除 rules 的方法跟以前 Centos 5, 6 相同.

如果上述命令沒有 lokkit，可以自己用 yum install lokkit 安裝。事實上 lokkit 也只是設定 iptables 把 http 和 ssh 打開，如果原本就有開了也不用執行或手動自己設定 iptables 也可以。
sudo lokkit -s http -s ssh

Reference
https://www.digitalocean.com/community/tutorials/how-to-migrate-from-firewalld-to-iptables-on-centos-7

New iptables default rules:
[ricky@thrift1 bin]$ sudo iptables -S | tee ~/firewalld_iptables_rules
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited

Edit the rule file so accept udp packets so that
sudo vi /etc/sysconfig/iptables
      8 -A INPUT -p udp -j ACCEPT
      9 -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
     10 -A INPUT -p icmp -j ACCEPT
     11 -A INPUT -i lo -j ACCEPT
     12 -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
     13 -A INPUT -j REJECT --reject-with icmp-host-prohibited
     14 -A FORWARD -j REJECT --reject-with icmp-host-prohibited
     15 COMMIT

Restart to make it effective

sudo sh -c 'iptables-restore -t < /etc/sysconfig/iptables'

systemctl restart iptables.service

Linux CentOS 7 SSH Connection Refused after Reboot

Description

On CentOS 7, I am using SSH fine for a month. After doing some operation with "systemctl status/mask/disable/restart firewalld" followed by "sudo reboot -h now", I cannot use ssh and got "connection refused" after reboot.

Problem

ssh 127.0.0.1

connection refused

Log

journalctl -u sshd | tail -100

Bad configuration option:ForwardX11Trusted

ssh failed

Solution

Comment "ForwardX11Trusted" option in sshd_config file as follows.

sudo vi /etc/ssh/sshd_config

X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost no
#ForwardX11Trusted yes

Outcome

journalctl -u sshd | tail -100

}

Design Pattern and Idiom

C++
NVI Idiom (Non-virtual interface, by creating a public non-virtual function that calls virtual private function that can be overridden by child class)

Java
"Double-Checked Locking" idiom, by checking null once, locking if null, and double checking null again, then initialize. It seems correct but it just works sometimes because by chance it is possible that thread B access the variable while thread A is locking and is partially creating the object. The correct solution is that after Java 5 the field should be declared volatile. The Java volatile field is equivalent to C++ atomic data member, allowing atomic assignment, and hence when thread B sees the variable it must be atomically fully created.

Installing CMake 3.7.0 on Windows 10

1. Download https://cmake.org/download/ > Platform > "Windows win64-x64 ZIP" > "cmake-3.7.0-rc1-win64-x64.zip", unzip as "C:\Program Files\cmake-3.7.0-rc1-win64-x64"

Note: It seems lucrative to download the common MSI file "cmake-3.7.0-rc1-win64-x64.msi" BUT it is used to install the CMake GUI which is designed to build the binary from CMake source files but NOT for installing the binaries. So DON'T waste your time to download the MSI file.

2. Add CMake's bin folder "C:\Program Files\cmake-3.7.0-rc1-win64-x64\bin" to System Envoronment Variables Path similar to JDK 

3. Run cmd.exe > "cmake --version" to verify the installation
C:\Users\rickypc>cmake --version
cmake version 3.7.0-rc1
CMake suite maintained and supported by Kitware (kitware.com/cmake).
