sessão de sombra FreeNX

Eu tenho o servidor FreeNX (Ubuntu 10.04) instalado e os usuários podem fazer o login bem. O problema surge quando os usuários gostariam de sombrear uma sessão. Simples e simples não funciona, embora o usuário cuja sessão está solicitando ser sombreado seja apresentado com a caixa de diálogo de confirmação (então, isso é um começo), mas falha logo após a confirmação. Usar a versão NoMachine não é uma opção, pois precisaremos de mais do que o máximo permitido sem pagar um preço absurdo.

Eu verifiquei que a mudança de AGENT_EXTRA_OPTIONS com e sem "-nolisten tcp" não tem efeito. Os usuários têm um limite de 5 sessões (portanto, 1 usuário + 1 sombra não ultrapassa esse limite) e o limite geral da sessão é suficientemente alto para nossos propósitos (por enquanto, estas são as duas únicas sessões).

Se alguém tiver alguma informação adicional para resolver este problema, seria muito apreciado.

A configuração do servidor:

cat /etc/nxserver/node.conf | grep -ve '^#' | grep -ve '^$'
SSHD_PORT=1209
DISPLAY_BASE=1001
SESSION_LIMIT=25
SESSION_USER_LIMIT=5
DISPLAY_LIMIT=25
ENABLE_PERSISTENT_SESSION="all"
ENABLE_MIRROR_VIA_VNC=1
ENABLE_DESKTOP_SHARING=1
ENABLE_SESSION_SHADOWING_AUTHORIZATION=1
ENABLE_INTERACTIVE_SESSION_SHADOWING=1
NX_LOG_LEVEL=7
NX_LOGFILE=/var/log/nxserver.log
SESSION_LOG_CLEAN=0

O nxserver.log como o usuário tentando sombrear tentativas: (usuário principal: "xxxx", sombreamento do usuário: "yyyy", no host: "host"):

Eu ainda não encontrei ninguém com isso funcionando corretamente com o Ubuntu e o Gnome em qualquer um dos lançamentos 10.04 e além.

Debian Squeeze Falha de montagem de convidado virtfs Linux 9p Onde o gentoo armazena o mongodb.conf? Deseja alterar a localização do dbpath

score 1 · Answer 1

O problema está no patch-getparam-url-decode.patch do time da freenx. Enquanto por si só o patch é som, ele tem um efeito colateral que faz com que getparam () retorne a primeira ocorrência de configuração do parâmetro, enquanto o código original estava retornando por último.

Essa diferença faz um truque sujo nas sessões de sombra, e nxnode tenta iniciar a sessão de sombra na mesma tela da sessão original.

A correção é editar / usr / lib / nx / nxnode: getparam e revertê-lo para o original:

 getparam()
 {
       stringinstring "&$1=" "$CMDLINE" || return 1
       echo "$CMDLINE" |  tr "&" "\n" | egrep "^"$1"=" | awk -F= '{ VAL=$2 } END { print VAL }' | sed 's|%24|$|'
       return 0
 }

A equipe do freenx saberá como corrigir isso corretamente em Python.

== fix-getparam-url-decode.patch ==
Add handling of '=' in the CMDLINE.
This was an issue when we were passing a command line for unix type of
 gnome-session --session=2d-unity
The '=' was not getting decoded and gnome-session would die.

Você está tentando liberar o FreeNX para um monitor existente? Tenho certeza de que não está funcionando. Aqui está uma solução adicionando em vnc mas no SUSE.
