작년에 ubuntu server 17.10을 설치했었는데…
citrix receiver가 안되서리..
ubuntu를 다시 설치했다.
이번엔 18.04 LTS 버전으로 설치했다.

Create a bootable USB stick on Ubuntu

https://tutorials.ubuntu.com/tutorial/tutorial-install-ubuntu-server

내 USB는 4GB짜리인데.. 다행히 2GB 공간만 있으면 되다니. 충분하고.
Startup Disk Creator 라는 프로그램만 있으면 되는데 없대서 설치했고.
튜토리얼 따라하니, 별 무리 없이 만들어졌다.

Install Ubuntu Server

https://tutorials.ubuntu.com/tutorial/tutorial-install-ubuntu-server

일단 USB로 부팅

‘Language’ 는 English 로
‘Keyboard’ 도 English 로
‘Install Ubuntu’ 로 선택하고
‘Network’ 설정하고, 집이나 보니 DHCP로 알아서 잡힌다.
‘Storage’ 는 파티션에 자신 없으니.. ‘Use An Entire Disk’로 선택했고
‘Profile’은 예전처럼 jin, jinia로 하고

- hostname : jin  
- user : jinia

  • 크롬브라우저 설치 (인증서 또 추가해야함)

  • Visual Studio Code

  • Citrix Receiver ( Debian Package에서 Full Package와 Web Package 둘다 설치)

나중에 확인할 것

  • remount

    file system table 의 options을 수정함. remount 하라고 하던데…
    /etc/fstab 파일을 수정하는 것임. options값을 바꿨음.

sudo vi /etc/fstab

nameservers의 addresses는 xxx.xxx.xxx.xxx 로 되어있으니, 적당히 본인이 사용하는 DNS ip를 적길..

  • Firefox 실행해서 인증서(POSCOICT_CA_256.cer) 추가

    리눅스 PC에서 인정서 가져올 디렉토리(extra) 생성했고.. extra 디렉토리에서 ftp로 확보한 인증서 파일 가져왔음.

    Firefox 실행
    -> 메뉴(우측상단)
    -> Preferences
    -> Privacy & Security
    -> Certificates
    -> View Certificates
    -> import
    -> Other Locations
    -> /usr/share/ca-certificates/extra/POSCOICT_CA_256.cer
    -> Check All (3 Trust)
    -> OK

cd /usr/share/ca-certificates
ls -al
sudo mkdir extra
cd extra
sudo sftp root@192.168.41.141
cd /usr/local
get POSCOICT_CA_256.cer
quit
ls -al
