scp permissão negada após 'endurecimento' com bastilha

4

Eu recentemente "endureeci" dois servidores Ubuntu usando Bastille , e agora obtenho permissão negada: scp sempre que eu tento arquivos scp.

    O login do
  • SSH funciona bem.
  • Eu tentei adicionar uma pasta / scp-dump com 777 permissões e ainda receber o mesmo erro, então não acredito que seja um problema de permissão.
  • O acompanhamento /var/log/auth.log não fornece informações, exceto

  • Usar o sinalizador -v com scp produz o seguinte:

Alguma ideia de onde a permissão negada pode estar vindo, arquivos de configuração que eu posso pesquisar ou outros logs que eu deveria estar olhando?

zsh:1: permission denied: scp parece não ter permissão para executar scp no lado remoto; verifique as permissões lá. Você já tentou executar scp nessa máquina para extrair os arquivos de outro lugar (vs. push)?
