Como iniciar uma sessão no Windows
Depois do software Sun Ray Windows Connector ter sido instalado, é possível iniciar uma sessão no Windows em uma DTU a partir do sistema
Windows.
1. Faça logon em uma DTU.
2. Inicie uma sessão do Windows em um sistema Windows.
% /opt/SUNWuttsc/bin/uttsc <options> <hostname.domain>
Se o sistema Windows estiver no mesmo domínio que a área de trabalho Sun Ray, não é necessário especificar o nome do domínio. No
entanto, se preferir, você pode especificar o endereço IP completo em vez de <hostname.domain>.
A publicação do comando uttsc sem opções, apenas com o nome ou endereço de um sistema Windows, exibe uma sessão do Windows na
DTU Sun Ray, conforme ilustrado na figura a seguir.
3
Guia do usuário do Sun Ray Connector for Windows OS 2.2
O tamanho padrão da tela é 640 x 480 pixels.
Para exibir a sessão em modo de tela inteira ou modificá-la de outra forma, consulte a página do comando man uttsc(1).
Para exibir uma sessão em vários monitores com o comando uttsc, você deve ativar o XINERAMA na DTU Sun Ray.
Como iniciar uma sessão do Windows no Java Desktop System (JDS)
O pacote de integração JDS (Java Desktop System) da Sun para o sistema operacional Solaris oferece uma CLI denominada uttscwrap, que
melhora a integração do Sun Ray Windows Connector com a área de trabalho JDS no Solaris 10. O pacote de integração JDS está incluído na
pasta Supplemental da imagem do software Sun Ray Windows Connector.
Utilize uttscwrap quando iniciadores de menu ou de área de trabalho estiverem definidos para iniciar sessões ou aplicativos do Windows em
vários sistemas Windows.
uttscwrap fornece uma caixa de diálogo de logon que permite introduzir credenciais para autenticação baseada em senha (
username/domain/password). As credenciais podem ser salvas na caixa de diálogo para utilização posterior. No próximo início de sessão, a
caixa de diálogo exibirá as credenciais.
Nota
uttscwrap foi concebido para armazenar em cache as credenciais somente para a autenticação baseada em senha. Ele não
pode ser utilizado com a autenticação por cartão inteligente. Para a autenticação por cartão inteligente, utilize diretamente o
Sun Ray Windows Connector (/opt/SUNWuttsc/bin/uttsc).
As credenciais são salvas separadamente para cada combinação de servidor e aplicativo do Windows. Essa convenção permite salvar credenciais
diferentes das seguintes maneiras:
para aplicativos distintos no mesmo servidor;
para aplicativos distintos em servidores diferentes;
para sessões de servidor distintas sem aplicativos iniciados.
As novas credenciais salvas para um servidor ou aplicativo substituem as credenciais salvas anteriormente.

Guia do usuário do Sun Ray Connector for Windows OS 2.2
Etapas
Para iniciar o Sun Ray Windows Connector com uttscwrap, especifique, na linha de comando uttscwrap, os mesmos parâmetros utilizados
na linha de comando uttsc.
1. Faça logon em uma DTU.
2. Inicie uma sessão do Windows em um sistema Windows.
% /opt/SUNWuttscwrap/bin/uttscwrap <options> <hostname.domain>
Se o sistema Windows estiver no mesmo domínio que a área de trabalho Sun Ray, não é necessário especificar o nome do domínio. No
entanto, se preferir, você pode especificar o endereço IP completo em vez de <hostname.domain>.
Como bloquear uma sessão no Windows
Este procedimento descreve como bloquear uma sessão do Windows quando a sessão de um usuário sair de uma DTU Sun Ray específica.
Nota
A implementação desse recurso depende de tecnologia não disponível em interfaces padrão e não públicas do Sun Ray, bem
como do uso de determinadas interfaces públicas do Sun Ray para outros fins diferentes da sua finalidade. Por essa razão, este
recurso não é oferecido como um recurso suportado.
Um método comumente usado para implementar o bloqueio de sessão é enviar os pressionamentos de teclas de bloqueio de tela para a sessão
do Windows usando xvkbd, que é chamado por utaction.
Você pode chamar utaction em um script Xsession.d ou xinitrc.d da seguinte maneira:
#!/bin/sh
XVKBD=/usr/openwin/bin/xvkdb
/opt/SUNWut/bin/utaction -d "$XVKBD -text '\Ml'" &
Como xvkbd não está disponível por padrão, você deve modificar a configuração de XVKBD no exemplo para que identifique corretamente o
local de instalação do xvkbd.
Nota
A sequência de pressionamentos de teclas \Ml ativa o bloqueio do Windows para sessões do Windows 2003/XP. Talvez seja
necessário substituir a sequência de pressionamentos de teclas em outras versões do Windows.
Como configurar o acesso à página do comando man uttsc
Para que os usuários possam acessar o comando man diretamente, adicione a seguinte entrada à variável MANPATH:
/opt/SUNWuttsc/man
Se o pacote de integração JDS (Java Desktop System) (somente Solaris) tiver sido instalado, então a seguinte entrada deveria ser adicionada:
/opt/SUNWuttscwrap/man
Os usuários poderão, assim, exibir uma página de comando man digitando o comando seguinte:
% man uttsc
5
Guia do usuário do Sun Ray Connector for Windows OS 2.2
Como configurar o acesso aos comandos do SRWC
Para que os usuários possam acessar os comandos do SRWC diretamente, adicione a seguinte entrada à variável PATH:
/opt/SUNWuttsc/bin, /opt/SUNWuttsc/sbin, /opt/SUNWuttscwrap/bin
O caminho /opt/SUNWuttscrap/bin é necessário somente se os seus usuários estiverem usando o pacote de integração JDS.
Como configurar um atalho de área de trabalho para iniciar uma sessão do Windows
No momento, não existe nenhuma interface gráfica do usuário disponível para o Sun Ray Windows Connector. No entanto, é possível configurar
iniciadores para que os usuários possam usar ícones de área de trabalho ou itens de menu para se conectar à sessão do Windows.
Para obter detalhes sobre como configurar os iniciadores, consulte a documentação sobre a área de trabalho do seu sistema operacional.
Mapeamento de unidades de disco locais
Qualquer arquivo pode ser montado e mapeado do ambiente Sun Ray para o ambiente Windows. Os sistemas de arquivos dos dispositivos de
mídia removíveis, como unidades flash, conectados às portas USB do servidor Sun Ray podem ser mapeados para o ambiente Windows usando o
comando utstoraged, onde aparecem como unidades montadas localmente.
Nota
Os nomes de arquivos do Windows não podem conter os seguintes caracteres: :*?"<>|. Certifique-se de que as pastas UNIX
redirecionadas não contenham nomes de arquivos que utilizem esses caracteres.
Para que os usuários possam acessar dispositivos USB conectados a uma DTU Sun Ray a partir de suas sessões do Windows, consulte About USB
Device Redirection.
Troubleshooting Windows Session Connection
Problem: Unexpected Time Zone Value
uttsc only considers time zones listed in /usr/share/lib/zoneinfo/tab/zone_sun.tab (for Solaris) and
/usr/share/zoneinfo/zone.tab (for Linux), as valid zones that can be converted into the equivalent time zones in the Windows session.
If the time zone is set to a value other than those defined in these files, then the time zone value in the Windows session can be unexpected.
