业务需要,调用了很多implants来执行对应系统上的命令, 但是无论怎么指定interactive.py中execute方法参数, 命令执行超时时间总是30.
后面通过扩展execute方法增加一个grpc超时参数后解决;具体方法如下:
async def execute_ex(self, exe: str, args: List[str], output: bool, timeout: int = 60) -> sliver_pb2.Execute:
'''Execute a command/subprocess on the remote system
:param exe: Command/subprocess to execute
:type exe: str
:param args: Arguments to the command/subprocess
:type args: List[str]
:param output: Enable capturing command/subprocess stdout
:type output: bool
:param timeout: grpc超时时间
:type timeout: int
:return: Protobuf Execute object
:rtype: sliver_pb2.Execute
'''
execute_req = sliver_pb2.ExecuteReq(Path=exe, Args=args, Output=output)
req = self._request(execute_req)
req.Request.Timeout = timeout * 1000000000 * 2 # 秒需要转换为纳秒单位
rpc_timeout = timeout + self.timeout
return (await self._stub.Execute(req, timeout=rpc_timeout))
