Píše mi to:

Server not installed or NX access disabled.

A nemůžu na to přijít.

Už to na Gutsy Gibbonovi někomu funguje? Mám nejnovější verze deb balíčků přímo z nomachine.com a stále autentizační chyba.

Máš vygenerovaný privátní key pro ssh ? Zkoukni návod na : https://help.ubuntu.com/community/FreeNX
hodně štestí ;o)

[Marek_]

Díky za reakci, klíče jsou použity ty defaultní. Ty to máš v provozu? Nebo jen píšeš, co tě napadlo?
Popř vypsal bys mi tu tvůj soubor /etc/ssh/sshd? Problém je, že se v příkazu ssh -i client.id_dsa,key to ptá na heslo nx uživatele, alespon myslím.

[Rastafar]

me na tady toto hlaseni pomohlo pridat usera nx do AllowUsers do /etc/ssh/ssh_config

cely soubor vypada ted takto (upozornuji ze mam SSH nastavene na port 40099):

Zkousim se na to pripojovat z druheho pocitace z windows a neni problem. Funguje jak spusteni nove session, tak shadow (nastavuje se v klientovi).

Po uprave tech konfiguraku je samo nutne restartovat ty daemony, takze:

Kód: [Vybrat]

sudo /etc/init.d/ssh restart
sudo /usr/NX/bin/nxserver --restart

Ten NX sem instaloval primo z deb baliku stazenych z http://www.nomachine.com/download-package.php?Prod_Id=5

Je tu nejaky limit na delku zpravy, tak sem to musel rozdelit...

At se dari

[Marek_]

přesně tak, z těchto balíků už mi to taky jede, natrápil jsem se s tím hodně, prostě nejdřív to nešlo a až s novou verzí ano.

Je ještě jiná metoda, a to balík freenx přímo v repozitářích, ale s tím jsem se trápil ještě víc.
Děkuji, ale toho nx uživatele jsem tam měl, přečetl jsem o tom snad všechny diskuze na webu. Prostě to pak záhadně začalo jít, takže ani nevím, co bylo špatně.
