问题 Port 8888 is already bound on my (OS X 10.13.5) system, by a process running inside a docker container: $ netstat -an | grep 8888 tcp6 0 0 ::1.8888 *.* LISTEN tcp4 0 0 *.8888 *.* LISTEN A python program which tries to bind to that port (using as close to the socket options of golang as I can manage), fails in the way I expect: import socket import fcntl import os def main(): sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) flag = fcntl.fcntl(sock.fileno(), fcntl.F_GETFL) fcntl.fcntl

问题 I want to access drives/folders/sub-folders/files on remote machines over network for a machine in C#. I know of a using WMI for this. However WMI might not be executable over remote machines due to security permissions. What are alternative way in C# to enumerate the folders/subfolders/files for remote machines over the network. Thanks! Gagan 回答1: Shared folders on a UNC path can be enumerated just like local directories, using the classes in the System.IO namespace, like Directory

问题 We have a networking problem in docker-swarm. The problem is below; we have virtualized environment over wmware ( vsphere 6.02) our servers are created from vmware say server1 and server2 we have a docker compose file defining a couple of services we have an overlay-network definition within docker-compose for docker-swarm when we deploy system using docker-swarm deployment is finished successfully, all containers gets ip from overlay network range. But the problem is if 2 containers (say

问题 Nomad has three different ways to map ports: Network stanza under group level Network stanza under config -> resources level port_map stanza under config level What is the difference and when I should use which? 回答1: First of all port_map is depricated, so you shouldn't be using that as part of task driver configuration. Up until Nomad 0.12, ports could be specified in a task's resource stanza and set using the docker port_map field. As more features have been added to the group network
