Try running Wireshark on the new computer to see the details about the traffic. You'll be able to determine if the machine is trying to send out spam once it has an Internet connection, and you can see where that traffic is destined, as well as any other outbound connections the system is attempting to initiate.

The manual should have directions for backing it up. It depends on the manufacturer, but most if not all of them have a menu option to backup the config, once you're able to access (login) to it.

I think this thread has gone on far too long. It was questionable to begin with, and it's turned into "Why I can't wait to surf for pr0n until I get home from school."

If you're at school, and they don't want you surfing, give it up. In case you haven't realized it yet, everything you do at school gets LOGGED, and it's just a matter of time before you get caught. Bypassing filters/proxies isn't that difficult to begin with, so if you haven't figured it out by now, either find someone at school who knows how, or wait until you get home from school to read your MySpace/FaceBook/whatever pages.

Flames by script kiddie wannabes will be diverted to /dev/null, so save your breath..

I think all the conversations talking about bypassing proxies should be banned/removed/modded. But hey, that's just me.

(They're there for a reason, people!)

Create a new A record (www) and give it the IP of the webserver, and create a pointer record and it should resolve fine. You might have to force a dns flush on the clients to see f it works right away.

The link is broken. Try http://dansguardian.org/ instead ;).

My bad :)

After reading the dig article "Kids Outsmart Web Filters" which links to a CNet News Article. I was wondering what measures you have used or know that have been used to bypass internet filters. I have the sole interest of securing internet access in my schools.
Thanks guys!

I've had a lot of success using Dan's Guardian (with Squid) on FreeBSD for schools. Drives kids crazy :)

You can't. To sniff it would mean that someone else has the username/password, and you would sniff it out of the network traffic to the router. Since you don't KNOW what it is, you can't sniff it. You'll probably have to reset the router, then reset your username/password, and restore the backup of the config that you saved when you configured the router. You did backup the settings, right? :)

If you allow traffic out on TCP 443, here's one way of bypassing your proxy. I've been doing this for awhile now. Of course, it's just a matter of finding out which ports are blocked from the inside and finding one that's open in the event 443 is closed, but you get the idea.

I could also do ARP spoofing, IP spoofing, or a number of different things to get around it, depending on how you've implemented it.

Considering it's a used system with someone else's version/license of XP, and according to rellie1977 he wanted to format the drive anyway, it's HIGHLY ADVISABLE that the drive get reformatted. Plus, there's no worries of whether or not the system is infected with viruses, malware, etc. if a clean O/S is installed on a fresh partition.

No worries :)

If you still need help, let me know.

Cheers.

If you want to repartition and format the hard drive, boot the system with a Windows 98 boot disk and type fdisk which will bring you to the screen you will need to define the partitions for your system. Then format and reinstall your O/S of choice. This will get rid of the dual boot issue, provided you wipe out all partitions with fdisk. If it's still a problem, try fdisk /mbr which rewrites the master boot record of the drive.

You can sign up for a free service @ http://freedns.afraid.org and have it take care of the reverse DNS for you, as long as you already have a domain registered. The instructions are on the site, and it's what I use for my personal site hosted on my personal server. No blah.dyndns.com or anything, just www.yourdomain.com They also provide a script that will automatically update your IP if it changes, so the domain will always resolve.

It depends on the switch - some models don't require them, others do. If you don't want to spend the money on switches, since you already have 2 hubs, just connect the hubs together with a crossover cable. There should be ports marked on the hubs to indicate where the uplink ports are located. The user manual should also tell you which ones they are, and how to connect them.

You'd have to configure your XP box as a router to do that, and I'm not entirely sure it has that capability. Would it be possible to use your Linux box as your firewall/router/gateway? You could use iptables to handle the routing and the firewall rules, including NAT, which might be your better option.
