Simply put, I would like to determine which (outgoing) ports are open and which are closed on my company's network. They have a firewall blocking most ports...so far I can only get through port 80 and port 443. I know for example, ports 23, 25, 110 and 6667 are blocked. So I may be over-thinking this, but what I think I need to do is find a way to listen on all ports (or at least a select list) on an external computer, then scan that computer's IP from inside the network to see what connects... The catch: I would like to open these ports for connections without having to install servers that actually use those ports. If we're talking a couple hundred ports, I don't want to install and configure a couple hundred server apps. (or all 65535?) Does anyone know of an app that will open 'fake' ports on a system and respond with some sort of generic server type? I know I've seen such an app before, but I just don't remember what it was called, and my google skillz are not coming through this time. Side note: I originally thought what I was looking for was a "leak tester" ...but this isn't quite right, as it is testing incoming ports, not outgoing ports. Thanks,

Where can I find detailed information on anti-virus software comparisons? I've heard of and seen some charts that display details such as catch rates and etc but have never known the exact source. Something like this perhaps: http://virus.untangle.com/ but a more broad spectrum, preferablly one that includes AVG and Avast! Also what is the best firewall for Windows Vista?

I have a Mac running OSX and use programs like Coda and Transmit to send out files. However, on certain networks, the only access I have to the net is via an http proxy (with no https, even!) . I understand there are ways to tunnel sftp over http but could not find an easy guide (or set of tools) to do so in a way where I can attach such tunneling to one profile (ie. CUSTOMER or WORK) and not have the proxying happen on another profile (ie. HOME) [more inside]

This is so embarrassing. I'd post it anonymously if I didn't think I'd have to provide more info. Anyway...I set up my new iMac last night and didn't even think about the firewall 'til this afternoon. So it was off for something like 12 hours of broadband, static-IP connectedness to the Net. How hosed am I, and is there anything I can do to put some or all of the horses back in the barn?

I have recently started a new job in charge of IT in a small lab <10 people. A while back the lab was badly hacked into and data etc. was lost (there is evidence this was an inside job btw). As part of my remit I am in charge of making sure this doesn't happen again. The company has a site license for anti-virus software so that is not an issue however we currently have no anti-spyware, personal firewall or rootkit / trojan detector etc. What I'm looking for is one or more products which I can install on the user's workstations which are effective in these areas. The most important point apart from actually working of course is that I can centrally administer the software and monitor what is going on - edit firewall rules etc. So what products would you recommend that might satisfy these requirements. Oh yeah all users including myself are running Windows XP so cross platform is not a problem.

I need to set up a wireless network at home. Here are my parameters: I have one business computer (the main desktop) that is plugged into the cable modem and has many firewalls and will not be on the wireless network. I want to have a reasonably secure but easy to use wireless router (with good range) that will work for both pc's and mac's hooked up to the cable modem. What is the best router to use and will I run into trouble with the desktop/firewalls? I've set up a network with an airport before and it was very easy. I'm looking for the same experience. thanks!

Warning: Networking Geekery Ahead Once upon a time I was able to use VNC viewer (the binary executable, not the java viewer) on my work Windows XP PC to connect to VNC server on my home Windows XP PC via Port 443. This allowed me to view and control my home desktop in a window on my work PC and thereby do an end run around the restrictive web filter/firewall at work. It was slow, but it was still useable and reliable.

I stopped using it for a couple of weeks when I lost my USB key. I recently found it and tried my VNC connection again from work. It doesn't work now. [more inside]
