I've got a web site that shows up just fine for everyone except me. I get a big fat "page not found" when I navigate to it even though it works fine in proxy browsers, I've used ipconfig/flushdns and cleared my browser cache. I'm sure it's a DNS issue of some sort, but have no idea what else to do. Help?

I have an idea for a simple piece of software. It would involve intercepting browser requests, checking the requested url (probably not ip address, so before that conversion takes place) testing the url and redirecting if it passes the test. The test will itself make a network connection. [more inside]

How do I give my computers subdomain names on my local network? For example, mylaptop.mynetwork.com, mydesktop.mynetwork.com, momslaptop.mynetwork.com, kids.mynetwork.com and so on? Do I have to set up some kind of local DNS or is there an easier way to do it in the router? I am not concerned at this point about being able to access the subdomains from the WAN although that would be handy later. It's the LAN I'm interested in. (Obviously I am using Bonjour right now but for I want to use the subdomains too). I own mynetwork.com and it points to a static IP. My LAN router is firewalled behind that. It's a WRT54G running DD-WRT. I have a spare computer I could run DNS on but I'd rather not have to do that. Everything is Macs running OS X, mostly Leopard.

Every once in a while (time between failures ranges from 1 hour to a few days), Firefox on my laptop suddenly and permanently (until reboot) loses its ability to do DNS lookups. Every page comes up with "Firefox can't find the server at www.foo.com." Other apps (and computers on the network) continue to work fine. It seems random; I haven't been able to correlate it with anything else on the machine. Closing and restarting Firefox doesn't restore its DNS lookup ability, but rebooting does. Googling only turned up the advice to disable IPv6, which didn't help. I'm currently running Firefox 2.0.0.8 on a Dell Inspiron 8600 running XP Home, but it's been an issue since at least 1.5. My only extension is Better Gmail, and I've tried disabling all extensions in the past. I'm at my wit's end - do any geniuses here have a clue?

Is hacking just to find out the identity of someone illegal? The short story is I'm being harassed via email, have IP addresses, headers, all that, but not enough stuff that comes off as threatening enough to get anyone in authority to care. I downloaded and tried to use BO2k and realized I'm in over my head. I contacted a few "public" hackers and asked for help, but they claimed they don't do that sort of thing. I just want to know who this person is who knows my name and details about my family. I don't want credit card numbers, passwords, etc. Is what I want illegal? Is it _how_ I want it that's the problem? Public replies or emails welcome: painted_nails_20@yahoo.com

I have a domain that I would like to forward to a free wedding site. I naively registered it through Dreamhost before realizing they don't provide this service unless you also buy a hosting package. I then signed up for URL Forwarding through Doster ($5 fee), not realizing that they pop-up obnoxious ads before doing the forwarding. So now I'm looking for an alternative provider for ad-free URL Forwarding.

I manage my own DNS for domain names (I'm a tecchie, I know what I'm doing and jumping through someone else's hoops for DNService has always ended in tears). I've only got the one machine at a co-loc, and registrars get cranky if you give only one authoritative DNS server, or two that are in the same net segment. Where does a nerd get some reliable secondary DNS? The dozen places I've checked out so far insist that I move all my DNS to them, when all I want is for them to mirror my zones.

Help me get my domain back. My domain name expired. My spam filter ate the renewal messages so I never saw them. Simple as that. I'm scrambling to fix the problem but I'm having big problems reaching an actual human at namecheap.com (the domain registrar I used) to renew. To make things worse, I run a small ISP so this affects over 1000 people directly. What can I do? I have backup domains but that switch would be very painful for my customers.
