[github] Public repo를 private으로 바꾸기

다솜돌이 Leave a comment

public project를 가져와서 혼자 몰래 뭘 해보고 싶을 때, Apache 2.0 License 등 derived works의 source code 공개 의무가 없는 프로젝트의 경우 private으로 바꿔서 작업을 해볼 수 있다.

다음과 같이 한다.

먼저 만들고 싶은 이름으로 github에서 project를 하나 private으로 만든다.

$ git clone --bare https://github.com/publicproject/project.git
$ cd project.git
$ git push --mirror https://github.com/myname/myproject.git

그리고 나서 실제로 clone해서 쓰면 된다.

$ git push https://github.com/myname/myproject.git

최신 코드로의 업데이트는 public repository를 여기다 remote로 추가해서 fetch & rebase하면 된다.

push는 public으로 fork해온 후 거기다 push 해서 pull request하면 될 듯.

SSH 접속 password 입력없이 RSA키로 접속하기

다솜돌이 Leave a comment

ssh 접속할 때마다 password 치기가 귀찮다…

클라이언트에서 키 생성

$ ssh-keygen -t rsa -N '' -q -f ~/.ssh/id_rsa

접속하려는 서버로 공개키 복사.

$ ssh-copy-id <account>@<server hostname>

위의 복사는 아래와 같은 동등하다. 위 명령을 했다면 아래를 할 필요는 없음.

$ scp ~/.ssh/id_rsa.pub <account>@<server hostname>:.ssh/authorized_keys

Ubuntu 20.04 내의 파일 저장 경로

WSL 1

%localappdata%\Packages\CanonicalGroupLimited.Ubuntu20.04onWindows어쩌고저쩌고\LocalState\rootfs\

예를 들어, C:\Users\dasom\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu20.04onWindows_79rhkp1fndgsc\LocalState\rootfs

WSL 2

\\wsl$ 를 입력하면 배포판이 보인다.

\\wsl$\Ubuntu-20.04

GUI

Xming 같은 Xserver를 사용해서 WSL로 설치한 Ubuntu 등에서 GUI 를 사용할 수 있다.

WSL 1을 WSL 2로 변환하기

WSL로 설치한 항목은 다음으로 확인 가능하다.

wsl -l -v

여기서 WSL Version이 1인 것을 다음과 같이 2로 바꿀 수 있다. 예제로 Ubuntu-20.04 를 바꾸고 싶다면 다음과 같이 하면 된다.

wsl --set-version Ubuntu-20.04 2

실행 시 기본 유저 바꾸기

명령 프롬프트에서 다음을 실행한다.

ubuntu config --default-user new_dasomoli

아래 글이 매우 정리가 잘 되어 있다.
