我正在使用以下命令来执行远程命令：

ssh -T -F ${ssh_config_path} ${remote_user}@{remote_host} '... here is command string ...'

ssh_config 文件如下所示：

Host __DASUSM__
    User MES
    Hostname ${remote_gateway_host}
    Port ${remote_gateway_port}
    IdentityFile ${identity_file_path}

Host *
    ProxyCommand ssh -F ${ssh_config_path} -q __DASUSM__ -W %h:%p
    ForwardAgent yes

例如，我在主机服务器中尝试了以下命令，它按预期工作。

ssh -F ${ssh_config_path} ${remote_user}@{remote_host} ls

但是，当我在 jenkins 中使用“Execute Shell”来执行它时，它不起作用。以下是详细错误：

为了比较，我粘贴了在主机服务器中运行良好的日志。

同时，我测试了以下，他们得到了相同的结果read failed。

/bin/bash << EOF
ssh -vv -F ${ssh_config_path} ${remote_user}@{remote_host} '... here is command string ...'
EOF

/bin/bash <<< "ssh -vv -F ${ssh_config_path} ${remote_user}@{remote_host} '... here is command string ...'"

ssh 127.0.0.1 << EOF
ssh -vv -F ${ssh_config_path} ${remote_user}@{remote_host} '... here is command string ...'
EOF

但如果我不使用输入重定向，它是有效的。

/bin/bash -c "ssh -vv -F ${ssh_config_path} ${remote_user}@{remote_host} '... here is command string ...'"

即便如此，我仍然无法让脚本在 jenkins 上运行。
期待你的答案...

===== 附加信息 (2018/11/05-2) =====

作为临时解决方法，使用 python 通过不在网关后面的第三/当前服务器执行远程命令。

python << EOF
import paramiko
with paramiko.SSHClient() as ssh:
  ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy)
  ssh.load_system_host_keys()
  ssh.connect("127.0.0.1", username="root")
  _, stdout, stderr = ssh.exec_command("ssh -T -F ${ssh_config_path} ${remote_user}@{remote_host} \"${command}\"")
  exit_status = stdout.channel.recv_exit_status()
  if exit_status != 0:
    # this is a demo, maybe you should raise an error
    print("error: " + "".join(stderr.readlines()))
  else:
    print("result: " + "".join(stdout.readlines()))
EOF

实际上，使用python直接执行它仍然会出错（如subprocess.run），因此使用paramiko模块来解决它。
