Estou tentando conectar-me a um servidor Ubuntu 16.04.3 LTS de um Desktop Ubuntu 16.04 LTS e recebo o seguinte registro SSH:
ssh -vvv -p portno [email protected]

No lado do servidor eu obtenho o seguinte log no auth.log
Did not receive identification string from xx.xx.xx.xx
Eu recebo a mesma mensagem para dois usuários diferentes
Eu tentei duas outras máquinas Ubuntu e Windows da mesma rede de origem para conectar ao servidor e foi bem sucedido!
Quando estabeleço uma conexão vpn do Ubuntu do meu desktop para um terceiro servidor e tento conectar-me ao meu servidor usando o SSH, ele é bem-sucedido!
Estava funcionando bem antes disso e estou me perguntando o que mudou no computador que causa isso!
