Os arquivos transitam pelo sistema A quando do sistema A do Windows eu inicio uma cópia do arquivo de \systemB\c$\folder1 para \systemB\c$\folder2?

Não é um grande problema quando os arquivos são pequenos e não numerosos, mas por outro lado, vale a pena remotamente para a máquina? Ou o Windows é inteligente o suficiente para apenas ordenar que o systemB faça a própria operação de cópia?

eu tenho uma corrente.pem

-----BEGIN CERTIFICATE-----
// My server cert signed by intemediate CA
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
// My intermediate cert signed by root CA
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
// My self signed root cert
-----END CERTIFICATE-----

bem como um server.key.pem

-----BEGIN RSA PRIVATE KEY-----
// Private key for server cert
-----END RSA PRIVATE KEY-----

Em seguida, hospedo um servidor que atende à cadeia com a chave privada do certificado de folha

openssl s_server -accept 1443 -cert chain.pem -key server.key.pem

Mas quando tento verificar a cadeia do openssl, ela falha

openssl s_client -connect 127.0.0.1:1443 -CAfile ca.cert.pem

Não parece que está apresentando o certificado intermediário ou raiz para que possa verificar a cadeia. O que estou perdendo aqui?

No meu cenário, o cliente teria a chave pública do certificado raiz confiável. Posso estar entendendo mal um monte de conceitos, sou novo nisso.
