Eu tenho uma configuração padrão:
Cliente (Windows 2019) -> Proxy HTTP -> Servidor SSH (Ubuntu) -> Servidor
Quero encaminhar minha porta local para o servidor.
Consigo me conectar com sucesso do cliente, usando esta configuração para o servidor. Não especifiquei nada relacionado ao proxy na minha chamada
ssh -v -p 22 -N -C -L 50000:WinServer:8080 user@SSHServer
Acho que isso significa que a implementação do OpenSSH está selecionando a configuração de proxy padrão do sistema cliente. Quero especificar explicitamente o proxy para poder isolar minha solução da configuração da máquina cliente.
Tentei a opção ProxyCommand da seguinte maneira:
PS C:\scripts> ssh.exe -vvv -C -L 50000:WinServer:8080 -o ProxyCommand="ssh.exe -v -W %h:%p -p proxy-port proxy-host" user@SSHServer

Minhas restrições:
- Não consigo alterar nada no proxy. Na verdade, minha solução será implantada em vários clientes, portanto não devo assumir nada além de um proxy HTTP.
- Tenho capacidade limitada para adicionar/alterar software no cliente. Gostaria de usar o recurso padrão da Microsoft, se possível. Qualquer software de terceiros precisaria ser qualificado, e isso é uma dor.
Qualquer orientação seria muito apreciada.
Obrigado,
