Python DNS Change Server

阅读更多关于 Python DNS Change Server

问题 What is the easiest way of changing the server that is queryed againest when using dnspython Ive been using the following, dns.resolver.query(hostname,type) However from the documentation it appears you can only change the file it looks at for its resolver servers. Any ideas ? 回答1: Resolver can load configuration either from the Windows registry or from /etc/resolv.conf . If you want to configure dns server manually, don't read system configuration (create it with configure=False ) and

Monitor defined DNS resolutions and change routes while writing back new IPs

阅读更多关于 Monitor defined DNS resolutions and change routes while writing back new IPs

问题 I have the problem that some FTP servers are not defined by IP anymore. Instead DNS names are provieded, so they may switch servers behind easily, while leaving customers with the problem of handling, because no routers and firewalls can get defined with DNS names (thank god it is this way). I had the idea to write a simple script to monitor defined DNS resolutions and change routes as needed by script. See the resulting scripts underneth in my answers. Thnx to MC ND. I am sure one could

How to redirect a root (naked) domain to www - heroku and zerigo

阅读更多关于 How to redirect a root (naked) domain to www - heroku and zerigo

问题 I have a domain example.com and www.example.com. I'm using Heroku and Zerigo for DNS.. Right now I have a forwarding from the root domain to the www.example.com from my Hostgator account but that's not working. I'd prefer to use Zerigo with the redirecting or by using an ALIAS. A lot of the articles I've found talk about ALIAS and ANAMES but I can't find those on Zerigo unless an ALIAS is specified by the letter A. Does anyone have a solution to pointing naked domains to their www using

问题 I use .net 3.5/c# I need to get server's IP, I was using this code: string strHostName = Dns.GetHostName(); IPHostEntry hostInfo = Dns.GetHostEntry(strHostName); string serverIpParam = hostInfo.AddressList[0].ToString(); return serverIpParam; However, after a switch to Windows 2008 server, my IP has letter format instead of usual format (digits). MSDN doesn't shed any light on this. Any ideas what I should change to get the server IP? Thanks 回答1: Did you looked at all the addresses that are

How to query authoritative name server to side-step propagation times?

阅读更多关于 How to query authoritative name server to side-step propagation times?

问题 I have a domain with 123-reg.co.uk and I've created a TXT record: I have tried to verify it has been applied by using both the dig and host shell commands, but it appears the TXT record isn't being found. For example... host -t txt integralist.co.uk ...returns: integralist.co.uk has no TXT record At first I assumed it might be a TTL issue and so I tried to use dig to query one of the authoritative name servers directly (thus avoiding a TTL caching concern), like so dig txt integralist.co.uk
