Eu preciso descobrir uma maneira de forçar RDP (Área de Trabalho Remota) a responder a uma porta específica Em vez de um RHP (Random High Port). Não estou perguntando como alterar a porta RDP "Listens", mas sim o contrário.
Estou tentando configurar um túnel experimental Avançar / Reverter SSH entre dois sistemas. Eu estou usando um terceiro sistema como um ponto de Pivot para esconder meu IP no túnel para a frente. Mas quero que o sistema em que estou Remoting através do túnel SSH Forward envie a resposta através de um túnel SSH reverso separado para uma porta "Especificada" em vez de um RHP. A idéia básica é que eu quero ser capaz de controlar quais portas eu quero ouvir e receber, e eu não quero que nada seja aleatório. Com isso dito, aqui está uma foto da minha configuração.
Editar: Todos os endereços IP da imagem foram alterados, o que tornará confuso mais tarde, quando você ler os registros que eu editei na pergunta. Os novos endereços IP são:
-
KGRAVES - 10.0.10.113
-
DEVILSMILK - 10.0.10.121
- DUCLAW - 10.0.10.120

Euprecisoqueaconexãodaáreadetrabalhoremotaseja"exibida" como se fosse proveniente de devilsmilk . Mas quero que duclaw envie a resposta diretamente de volta para kgraves-pc sem passar por devilsmilk . Então para kgraves-pc a RDP session está sendo enviada para o localhost que é então encaminhado via ssh tunnel através de devilsmilk to duclaw , mas os pacotes RDP que estão sendo recebidos em resposta a isso conexão são recebidas diretamente de Duclaw .
Meus comandos são os seguintes e todos eles são executados no mesmo console CYGWIN ssh em kgraves-pc , exceto pela conexão mstsc que fiz de outro terminal CYGWIN em kgraves-pc :

Conexão de área de trabalho remota estabelecida. E, como você pode ver, parece que está vindo de devilsmilk on duclaw . Mas de acordo com kgraves-PC está voltando de Devilsmilk . Então, o que eu pensava que estava acontecendo na verdade não era. Eu pensei que Duclaw estava enviando a sessão RDP de volta para kgraves através de um caminho separado, mas acontece que não foi. Eu não tenho certeza se estava funcionando da última vez e eu tinha uma configuração diferente ou se eu estava imaginando coisas. Mas agora que eu consegui tudo reconfigurado e voltando e rodando depois do meu problema com meus servidores ssh, ele definitivamente não está mais fazendo isso.
Issoéwiresharkemexecuçãoemkgraves-pcduranteasessãoRDP:
Portanto, meu problema ainda é que eu quero que Duclaw envie a sessão RDP de volta para o Kgraves-pc através de um túnel reverso totalmente separado. Isso é o que preciso acontecer e não consigo descobrir como fazer.
Não só preciso de duclaw para enviá-lo de volta em um túnel separado diretamente para kgraves-pc sem passar por devilsmilk , mas também preciso controlar para qual porta efêmera ele será enviado. Eu quero enviá-lo para a porta :44444 em vez de uma porta efêmera aleatória. Ele está usando :48809 aleatoriamente na depuração detalhada ssh impressa acima.
Espero que isso ajude, se não ... desculpe por confundi-lo ainda mais.
