Estou tentando configurar o OpsCenter adicionando meu nó Cassandra localhost (para teste). As credenciais de login que usei para o SSH têm direitos sudo / root, mas recebo o erro:
scp: /tmp/tmpXInRfq: Permission denied
Eu posso entender que o protocolo SCP (que é aparentemente usado no OpsCenter) não pode fazer algo como executar um comando 'su'. Mas o que eu estou errado?

O que estou errado?
Obrigado antecipadamente!

OpsCenter usa um arquivo temporário na própria máquina do OpsCenter para facilitar o ssh. Portanto, em vez de ser um problema com as credenciais de login que não possuem direitos sudo, acredito que, na verdade, o usuário que está executando o OpsCenter não tenha permissões para criar arquivos tmp em: %código% Na máquina executando o OpsCenter. Você pode confirmar se o usuário que está executando o OpsCenter pode tocar em um arquivo nesse local?
Obrigado.
