안녕하세요.


오늘은 U5PVR 에 Spreed WebRTC 서버를 설치해 보도록 하겠습니다.


먼저 하기 글을 참고해 주시길 바랍니다.


http://djjproject.blog.me/220896389747



Spreed WebRTC 서버는 WebRTC 를 이용한 영상통화를 웹페이지에서 구현하는 것입니다.


크롬, 파이어폭스, 오페라 등과 호환이 가능하고 엣지 브라우저와는 호환이 되는지 모르겠습니다.


안드로이드 크롬에서 작동 가능하고 여타 아이폰에서 크롬을 설치했다고 해서 동작하지는 않습니다.



1. 네트워크 구조 이해하기


대부분 네트워크를 사용하시는 분은 아래와 같이 2가지의 구조로 연결이 되어 있을 것입니다.


(공유기를 2개 통하는 그런 구조는 예외. 너무 귀찮아져서 뺍니다.)


(U5PVR 이 상당히 과장되게 그려졌네요 ㅎㅎ..)



Spreed WebRTC 는 미디어 릴레이가 필수 입니다.


사진에서 순서대로 첫번째 두번째라고 하면, 첫번째는 U5PVR 위치가 NAT 환경이고 두번째는 공인아이피에 바로 물린 상황입니다.


공인아이피에 물린 경우에는 stun server 만 경유하면 음성 및 영상이 릴레이가 됩니다. 

(이 경우에는 구글의 오픈 서버를 이용하면 되기 때문에 문제가 없습니다.)


그러나 NAT 상에 물린 경우에는 미디어와 영상을 turn 서버에서 릴레이 해야합니다.

turn 서버에 음성과 영상이 경유 되어 사용자끼리 통신이 되기 때문에 서버에 부하가 많이 참으로 무료로 제공되는 서버는 거의 없습니다.


U5PVR 에 turn 서버를 꼭 두지 않아도 되고 다른 서버에 turn 서버를 설치해서 운영해도 됩니다.



2. Spreed WebRTC 서버 설치하기


먼저 빌드환경을 구축해야 함으로 의존성 패키지를 설치합니다.

테스트를 진행하기 위해서 서비스를 시작합니다.


root@u5pvr-debian:~/spreed-webrtc# service spreed-webrtc start

3. Spreed WebRTC 테스트하기


테스트는 먼저 내부망에서 한번 해 보도록 하겠습니다.


외부망의 경우 미디어 릴레이 관련 문제가 생기기 때문에 아직은 안됩니다. ㅎㅎ


PC 에 마이크가 없어서 핸드폰으로 한번 테스트 진행 해 보았습니다.


웹 브라우저로 https://192.168.100.35:8443 으로 접속합니다. 셀프 사인이기 때문에 보안에 위험하다? 는 에러가 뜹니다만 제낍니다.


그리고 마이크 권한 설정을 해 준다음 아래처럼 사용이 가능합니다.




예전에 찍어둔 스크린샷 입니다. PC 에서는 이렇습니다.



정상적으로 잘 됩니다.



4. U5PVR 이 공인아이피를 받는 경우


이 경우에는 STUN 서버만 설정하시면 됩니다.


Spreed WebRTC 서버 설정파일을 수정합니다.


root@u5pvr-debian:~/spreed-webrtc# nano /etc/spreed-webrtc-server/server.conf


[app]

; HTML page title

;title = Spreed WebRTC

; Version string to use for static resources. This defaults to the server

; version and should only be changed when you use your own way to invalidate

; long cached static resources.

;ver = 1234

; STUN server URIs in format host:port. You can provide multiple seperated by

; space. If you do not have one use a public one like stun.spreed.me:443. If

; you have a TURN server you do not need to set an STUN server as the TURN

; server will provide STUN services.

stunURIs = stun:stun1.l.google.com:19302        # 언코멘트 후 google stun 주소를 넣습니다.

; TURN server URIs in format host:port?transport=udp|tcp. You can provide

; multiple seperated by space. If you do not have at least one TURN server then

; some users will not be able to use the server as the peer to peer connection

; cannot be established without a TURN server due to firewall reasons. An open

; source TURN server which is fully supported can be found at

; https://code.google.com/p/rfc5766-turn-server/.

;turnURIs = turn:turnserver:port?transport=udp

; Shared secret authentication for TURN user generation if the TURN server is

; protected (which it should be).

; See http://tools.ietf.org/html/draft-uberti-behave-turn-rest-00 for details.

; A supported TURN server is https://code.google.com/p/rfc5766-turn-server/.

;turnSecret = the-default-turn-shared-secret-do-not-keep


이 후 서버를 재시작 하고 외부에서 접근해도 잘 작동합니다.



5. U5PVR 이 NAT 상태인 경우


이 경우는 U5PVR 이 공유기 밑에 물려있는 상황입니다.


이 상황에서는 어쩔 수 없이 turn 서버를 설치해서 운영해야 합니다.


turn 서버는 꼭 U5PVR 에 있을 필요는 없습니다. 단일화의 목적이니 U5PVR 에 설치해 보도록 하겠습니다.

잘 구동중입니다.


turnserver 설정파일을 아래와 같이 수정합니다.


root@u5pvr-debian:~# mv /etc/turnserver.conf /etc/turnserver.conf.bak    #기존설정파일 백업

root@u5pvr-debian:~# nano /etc/turnserver.conf

그 후 turnserver 를 재시작 합니다.

다음으로 공유기에서 3478 포트를 TCP/UDP 포트 모두 열어줍니다.


추가적으로 8443 포트도 TCP 로 열어줍니다.



다음으로 Spreed WebRTC 에서 turnserver 를 활용하도록 수정합니다.


root@u5pvr-debian:~# nano /etc/spreed-webrtc-server/server.conf



[app]
; HTML page title
;title = Spreed WebRTC
; Version string to use for static resources. This defaults to the server
; version and should only be changed when you use your own way to invalidate
; long cached static resources.
;ver = 1234
; STUN server URIs in format host:port. You can provide multiple seperated by
; space. If you do not have one use a public one like stun.spreed.me:443. If
; you have a TURN server you do not need to set an STUN server as the TURN
; server will provide STUN services.
;stunURIs = stun:stun1.l.google.com:19302        # stun 은 turnserver 에서 관리 함으로 언코멘트 합니다.
; TURN server URIs in format host:port?transport=udp|tcp. You can provide
; multiple seperated by space. If you do not have at least one TURN server then
; some users will not be able to use the server as the peer to peer connection
; cannot be established without a TURN server due to firewall reasons. An open
; source TURN server which is fully supported can be found at
; https://code.google.com/p/rfc5766-turn-server/.
turnURIs = turn:djjproject.iptime.org:3478?transport=udp        # turnserver 정보를 입력합니다.
; Shared secret authentication for TURN user generation if the TURN server is
; protected (which it should be).
; See http://tools.ietf.org/html/draft-uberti-behave-turn-rest-00 for details.
; A supported TURN server is https://code.google.com/p/rfc5766-turn-server/.
turnSecret = djj9405        # 언코멘트 후 turnserver 의 암호를 입력합니다.


turnURIs 의 경우 turn:아이피 or 도메인 주소:포트?transport=방식 입니다.


설정이 완료 되었습니다.


재시작 합니다.


root@u5pvr-debian:~# service spreed-webrtc restart

Killing Spreed Webrtc Server: done

Starting Spreed Webrtc Server: done

root@u5pvr-debian:~#


부팅시 자동실행할 경우 아래와 같이 설정하시면 됩니다.


root@u5pvr-debian:~# update-rc.d spreed-webrtc defaults



6. Test 고고@!


태블릿을 동원하여 실험을 진행했습니다.


델베뉴8프로 를 사용했고 전면에 카메라가 있습니다 ㅎㅎ..


반대부분은 넥서스5 입니다.


델베뉴8프로는 외부 다른 와이파이에 연결 / 그리고 넥서스5는 KT 망 사용 / U5PVR 이 있는 위치는 U+ 기업인터넷 (공유기 상태 NAT) 입니다.


이 상태에서는 turnserver 를 사용하지 않으면 작동이 되지 않습니다. 5번에서 정상적으로 설정을 했기 때문에 아래처럼 통화가 잘 됩니다 ㅎㅎ






매우 잘 됩니다 ㅎㅎ



감사합니다.
