[SDN}Mininet + ONOS 튜토리얼

ODL(OpenDayLight) 쪽에 데드락이 절려버려서 이러지도 저러지도 못하고 있다가

ONOS를 발견해서 해보고 있습니다 

현재 테스트 환경은 Ubuntu 18.04 LTS (GNU/Linux 4.15.0-23-generic x86_64) 입니다.

먼저 mininet 설치 

mira@opendaylight:~$ sudo apt-get install mininet

역시 편한 apt-get

mira@opendaylight:~$ sudo mn --test pingall

sudo: unable to resolve host opendaylight

이걸 키고 해당 머신의 8181 포트로 http://192.168.0.19:8181/onos/ui/login.html 들어가면 웹인터페이스가 열림

물론, 항상 저상태로 둘수는 없을것 같은데, init폴더에 데몬을 올릴수 있는 스크립트가 있을것 같아서 저걸로 키고 끄면 될듯

일단 테스트가 우선이니

GUI Configuration Notes

• The onos-gui feature must be installed in ONOS.
• The GUI listens on port 8181.
• The base URL is /onos/ui; for example, to access the GUI on localhost, use: http://localhost:8181/onos/ui
• The GUI has been developed to work on Google Chrome. The GUI has been tested on Safari and Firefox and minor compatibility adjustments have been made; these and other browsers may work, but have not been extensively tested, and are not actively supported, at this time.
• The key bindings associated with any view will work on any keyboard. The "Cmd" (⌘) key on an Apple keyboard is bound to the same key as the "Windows" or "Alt" keys on Windows or other keyboards.
