GDM + XDMCP dzia

kleofas · Post autor: **kleofas** » 21 kwietnia 2009, 23:34

Witam,

Potrzebne mi jest środowisko do pracy zdalnej, do którego można się połączyć z dowolnego miejsca przez protokół X11. Natknąłem się na protokół XDMCP. Skonfigurowałem gdm do serwerowania zdalnych sesji, ale... No właśnie. Lokalnie działa, a zdalnie już nie chce. Kiedy próbuję się zalogować mam taki oto log (w syslogu):

Na routerze wszystkie porty mam przekierowane do serwera, ale zdaje mi się, że nie w tym problem - po próbie logowania na serwer otrzymuję pusty ekran w kratkę + kursor (standardowy blank), a na serwerze pojawia się nowa instancja Xservera, więc połączenie raczej ok. Nie wiem jednak dlaczego serwer się zapętla i koniec końców nie dostaję gdmgreeter'a. Googlam już od tygodnia i mało informacji się doszukałem. Próbowałem konfiguracji ręcznej oraz przez gdmsetup. Niestety nic, co znalazłem, nie pomogło. Napisanie tego posta to mój akt desperacji i po prostu rozłożenie rąk.

Pozdrawiam.

Prawdę mówiąc nie rozumiem tego loga (a raczej nie czytałem zbyt uważnie).

Długo walczyłem z KDM+XDMCP i w końcu jakoś go zmusiłem do działania, jak z GDM nie wiem.
Tak czy siak XDMCP przez internet działa bardzo wolno. Potrzebne jest, o ile dobrze pamiętam, pasmo rzędu 1-2MB/s od serwera do klienta żeby ładnie chodziło. Z pobieraniem (tam gdzie klient) najczęściej nie ma problemu gorzej z wysyłaniem (tam gdzie serwer).
Technologia ta, moim zdaniem nadaje się tylko do połączeń LAN. Zdalnie spróbuj przez VNC (troszkę inaczej działa - bo "podgląda" zalogowana sesje Xów) lub NX (tuneluje X przez ssh i robi sporo bajerów optymalizacji tego co faktycznie przesyła).
A całkiem z innej beczki - o ile Ci to pasuje - możesz spróbować postawić Xserwer po stronie klienta i tylko uruchamiać zdalnie aplikacje. Nawet to działa - oczywiście też bez cudów z prędkością, ale na upartego da się

Trochę nie na temat ale myślę że coś pomoże

Zmieszałeś mnie nieco - o ile wiem VNC śle bitmapy, a XDMCP wywołania funkcji XServera. Być może się nie znam, ale wydaje mi się, że VNC jest wolniejsze od zdalnego X11. Czy mógłbyś podzielić się swoim konfigiem KDM oraz Xaccessem, ewentualnie wysłać mi na PW jeśli nie chcesz upubliczniać? Z KDM też próbowałem, ale nic mi się nie udało, błąd segmentacji łapał przy próbie połączenia (podobno według historii jakiejś listy mailingowej to jakiś stary błąd w Debianie) i szczerze mówiąc nawet wolałbym KDM od GDM.

W pliku kdmrc cala sekcja XDMCP wyglada tak:

Kod: Zaznacz cały

[Xdmcp]
Enable=true
Willing=/etc/kde3/kdm/Xwilling

Xaccess zostawilem tak jak jest, bo tylko do testow tego potrzebowalem. Restart kdm i dziala

Edit: Przepraszam, w Xaccess wpisalem po prostu '*' w wolnej linii zeby dac dostep z kazdego miejsca.

VNC sle bitmapy, ale tylko te fragmenty, ktore musza byc przerysowane, dodatkowo je kompresuje i potrafi uzywac mniejszej ilosci kolorow. XDMCP (X11) wysyla wywolana funkcji, ale w postaci nie zmienionej. Poza tym duzo programow uzywa praktycznie jednej funkcji - postaw pixel. Czyli: polozenie X, Y, oraz kolor w 24bitach, co daje duze wymagania.. VNC nawet jakby wysylal calosc za kazdym razem, to nie podaje polozenia pixela. Dodatkowo X11 ma wieksza czestotliwosc odswiezania pozycji myszy niz VNC co tez wymaga wiekszego transferu.
Co do tego co napisalem o XDMCP glowy nie dam, ale widze ze dziala wolniej. U mnie w domu polaczenie laptop-stacjonarny przez WiFi czasem zdycha, natomiast VNC leci bez problemu na komputer zdalny z neostrada 1MB.

GDM + XDMCP dzia

GDM + XDMCP działa lokalnie, a z zewnątrz juŻ nie.
