Estou conectando a uma instância do ubunto, executando alguns testes do Apache / JMeter, e tentando usar o scp para pegar os arquivos de log dos testes.
Eu conecto com o seguinte comando:
ssh my-host.amazonaws.com -l my-username
Consigo me conectar e posso executar os testes. No entanto, eu ainda tenho que executar um comando scp sem um erro.
Estou usando o seguinte comando:
scp [email protected]:~/my-file-name.jtl ./
Eu recebo imediatamente o seguinte erro:
Permission denied (publickey).
Alguma ideia de qual poderia ser o problema? Eu tenho direitos para se conectar à máquina em primeiro lugar. Além disso, o nome de usuário "my-username" é compartilhado por alguns usuários de teste, e outros são capazes de executar o comando scp sem problemas.
Edit: aqui está minha saída de tentar o comando scp com o argumento -v:
my-username@ip-xx-xx-xxx-xx:~$ scp -v
[email protected]:/home/ubuntu/jmeter.log ./
Executing: program /usr/bin/ssh host my-host.amazonaws.com,
user ubuntu, command scp -v -f /home/ubuntu/jmeter.log

Welcome to Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-95-generic x86_64)
Você não está executando os dois comandos da mesma máquina ou do mesmo usuário.
Uma saída diz que /home/ubuntu/.ssh/id_rsa é usado, outro diz /c/Users/jdoe/.ssh/id_rsa
Então você provavelmente está usando a chave errada no caso do scp, vindo do diretório errado.
