암호화 지원하지 않아 안전하지 않다라...

XDMCP is inherently insecure as it does not encrypt your traffic. XDMCP is analogous to telnet, and therefore they share the same security issues.

netsarang의 Xmanager는 XDMCP를 자체 지원하는데..

2단계 거쳐서 하라는거 보면 putty의 X11 포워딩 삘이..

아무튼 실험해보니..

putty + Xming으로

arcfour 설정해주니 썩 나쁘지 않은 속도로 반응


스트림 사이퍼.. 블록이 아니라 더 빠르게 응답하는 걸려나?

Update: Ben Harris has written an Internet-Draft (draft-harris-ssh-arcfour-fixes, now RFC 4345) describing a way of using Arcfour reasonably securely with SSH-2, and PuTTY now implements this. Note that this document defines the "arcfour256" and "arcfour128" ciphers; PuTTY still does not support the less secure "arcfour" cipher, and we have no plans to make it do so.

(Support was first added in 2005-04-22, but uonly under private names defined in an earlier draft: "arcfour256-draft-00@putty.projects.tartarus.org" and so on. Only from 2005-09-04 do we support the IETF names, which also appear in OpenSSH from 4.2.)

엥 다시 실행해보니..

XDMCP 보다 오히려 arcfour가 빠른 느낌이다 ㄷㄷ

xnest의 사용법의 예제...?

일종의 vm 처럼 보이는 기분 ㅋㅋㅋ

$ Xnest :1 -query localhost -geometry 1024x768
