passwd

ssh connection

ssh root@127.0.0.1 -p 50022

• Other target

ipconfig # use this command e.g. 192.168.1.xxx

ssh -p 50022 root@192.168.1.xxx

use static ip

• IP address: 192.168.1.99
• Subnet mask: 255.255.255.0
• Gateway: 192.168.1.1
• DNS server: 8.8.8.8

add ssh key

ssh-keygen -t rsa -b 4096 -C "ryansoq@gmail.com"
cat /root/.ssh/id_rsa.pub

clang format

if clang-format --version &> /dev/null
then
   clang-format -style=WebKit -i main.cc
   clang-format -style=WebKit -i example.cc
fi
// clang-format -style=file -i activations.h
