Linux下的网络配置 - CentOS 6.x 文本关键字：Linux、CentOS、网络服务、eth0、网卡配置项 一、查看网络信息 通常我们查看本机的网络是否正常，主要需要知道的就是网卡是否在正常工作，相关的网络信息（IP地址、广播地址、子网掩码等）是什么。除此之外，我们需要测试当前机器是否连入互联网，或者是否能够与网关正常通信。 1. ifconfig ifconfig是一个最常用的，可以查看和设置各网卡的工具。 直接使用ifconfig命令：列出所有当前已启用的网卡信息 使用ifconfig和网卡名称：具体查看某一块网卡信息 2. ping 使用ping命令可以用于测试网络的连通性，可以方便我们排查问题，通常首先会检查网关的连通性，随后是外网的某一地址，如：百度。 检查与网关的连通性 检查与外网某一地址的连通性 二、修改网络配置 1. 网卡配置项 DEVICE：设备名称 TYPE：网络类型（以太网等） ONBOOT：开机时是否自动启用（yes/no） HWADDR：MAC地址（物理地址） BOOTPROTO：网卡获取配置的方式（dhcp/static/none/其他） IPADDR：IP地址 NETMASK：子网掩码 GATEWAY：网关地址 BROADCAST：广播地址 DNS：DNS服务器地址 NAME：网卡名称 USERCTL：普通用户是否可以控制（yes/no）

问题 I know I'm an idiot, but I can't pull the domain out of this email address: 'blahblah@gmail.com' My desired output: '@gmail.com' My current output: . (it's just a period character) Here's my code: import re test_string = 'blahblah@gmail.com' domain = re.search('@*?\.', test_string) print domain.group() Here's what I think my regular expression says ('@*?.', test_string): ' # begin to define the pattern I'm looking for (also tell python this is a string) @ # find all patterns beginning with

Why does WCF complain over identity check failure?

由 ≡放荡痞女 提交于 2019-12-18 14:09:15
问题 I'm creating a WCF application where I'll be using certificates to encrypt the communication between the client and server. In my development environment, I want to use a test certificate / self signed certificate which I've created using makecert. (Only the server will have a certificate, the client won't). I've installed the certificate into a certificate store, and everything is working fine. On the client, certificateValidationMode is currently set to "false", since I'm working with a

Http Request - Bypass DNS [.Net]

由 一个人想着一个人 提交于 2019-12-18 13:21:39
问题 Is it possible (and if yes, how) to bypass DNS when doing a HTTP request ? I want to hit directly a front-end with an HTTP request, without getting through NLB but with the correct host header. As I have the IP of my server, I just need to bypass the DNS. I tried to use WebRequest, replacing the URL with the IP and setting the Host header, but this header is protected. How can I do that ? Do I need to create the HTTP request myself ? Note: editing host file is not an option 回答1: At the time

Don't change the default /etc/resolv.conf . 回答1: @holys "github.com/miekg/dns is too heavy for me" It's not that heavy: package main import

Can I temporarily override DNS resolution within a .NET application?

由 狂风中的少年 提交于 2019-12-18 11:49:18
问题 I have some wrapper code that runs a set of NUnit tests that scan live websites for certain response codes. I'd like to run these tests against a different server. When running manually, I can do this by editing the /etc/hosts file in Windows\System32\drivers and temporarily setting www.mysite.com to 10.0.0.whatever Is there any way I can do the same within a .NET console application - temporarily override a DNS record or somehow intercept the resolution and return a different IP address?

URL Redirection and 1and1

由 一世执手 提交于 2019-12-18 09:55:49
问题 I've got an app up and running on Heroku. I've purchased a top level .com domain from 1and1 (I have other sites there, so I thought that would make life easier). When I attempted to redirect to my Heroku app, I was not allowed to modify the CName alias record like I have done for other sites - which were all subdomains. I was given two options: Frame redirect or HTTP redirect, I've tried both. The frame redirect doesn't seem to function at all - the page stays blank. The HTTP redirect does

Is there a way to make a websocket reachable through a SRV DNS record?

由 只愿长相守 提交于 2019-12-18 09:45:26
问题 I swear I googled this. I was wondering if there is any way to connect to a WebSocket service by resolving a SRV DNS query. In principle, this sounds reasonable to me, e.g., in a situation where the port where the service is going to be listening depends on the host and there is not a fixed port. For example: Server A listens with a WebSocket on port 1234. Server B listens with a WebSocket on port 1235. Server NS assigns a CNAME to A, and a CNAME to B. It also adds a SRV entry that points to
