Estou usando uma conexão ssh com um servidor remoto. Eu ofereço uma chave rsa. Agora migramos o cliente para um novo servidor. O servidor antigo era o RHEL 5.11, o novo é o RHEL 7.4.
Eu uso a mesma chave rsa de antes. A conexão recebe um "debug1: O servidor aceita a chave: pkalg ssh-rsa blen 277" Mas então ele recebe "debug2: input_userauth_pk_ok debug3: sign_and_send_pubkey: RSA debug3: send packet: digite 50 debug3: receber pacote: digite 51 "e recusa a chave.
Eu uso a mesma chave para conectar-me a outro servidor sem problemas e ainda posso me conectar ao servidor remoto usando o cliente antigo. Infelizmente não consigo ver os logs do servidor remoto.
O cliente antigo usava SHA1 - os novos usos SHA256. Isso poderia ser um problema?
