i think that you should not put 64k users with upstream and downstream classes and filters for each of them on the same interface. You can repeat the handlers for each interface you have, so add more interfaces. You will need a incredible work/server/NIC to have this things. If the server crashes, you will have … Read more
The dsn=2.0.0 and a correct relay= means that Bell’s mail server has accepted the message. However, this doesn’t mean that it will allow the message to be delivered to the user’s mail box. In this instance the most likely explanation is that Bell South’s spam filters have cleaned your message out before reaching the user’s … Read more
Here’s the method that worked for me: Sync the files and databases with the new server. Perform a re-sync just before cut-off. Change the DNS to point to the new server. Forward the request coming to the old ip to the new server until DNS propagation completes. Here’s how I would do the step 4: … Read more
Usually for a large contract you should be able to negotiate at least read only access to their edge router. However even as building a new data center near one of our ISP connection (~40m cable) and a pretty big contract back then i was unable to get that. There was often some data leaking … Read more
This is an unfortunate irritation. Multiple DNS servers are supposed to be to increase reliability, but in practice it frequently has the reverse effect. The problem is that the client only waits so long for a response, and the server waits about that same amount of time. Say you have two DNS servers, A and … Read more
From what I’ve read on other answers, it feels like you’re asking specifically how your ISP is managing to add “blocked.aspx” to the end of your domain. If that’s the case, let’s look at a case study: You have a web server running on http://mysite.mine/, which a public, completely trustworthy DNS resolves to public IP … Read more
RFC 1035 says: MNAME The <domain-name> of the name server that was the original or primary source of data for this zone. although in practise this MNAME field in the SOA is mostly unused these days. However if you’re using DNS dynamic updates then it must refer to the name of the DNS server which … Read more
I just have to throw in my two cents: If you’re looking to “start a business” and are a programmer, go with a hosting provider. Less headaches, you have someone else to deal with the network and hardware issues. If you’re planning on hosting things for anyone other than yourself, DO NOT host it in … Read more
It sounds like in effect you want to pay a users ISP to zero-rate traffic to your site, similar how to some cell carriers allow you to stream video from certain websites without impacting your allocation. If you are a major company like Google or Netflix then this has a ghost of a chance of … Read more
I’m going to put this as gently as I can: Wireless networks (802.11) suck. The 2.4GHz band (802.11b, g, and some n devices) is a festering pit of radio noise. Everything from baby monitors to microwave ovens pollute this section of the spectrum, and the wanton proliferation of wireless networks has it so congested that … Read more
