    Troubleshooting a T1 line

    We've been having a problem for a while now with one of our T1 circuits. It will drop repeatedly through the day for anywhere from 30 seconds to 15 minutes. The location is way out in BF Egypt and we dont have anyone at the site capable of doing physical troubleshooting. So I've been limited by...

    Registered to take CISSP Exam

    I took the plunge and registered to take it. A cool $500 bucks, plus the 60 for the official study guide. I had to put out my wallet with an 18-wheeler-sized fire extinguisher. Assuming they have a slot open, I'll be taking it August 29 in Austin TX. If I pass it, I'll be an "Associate of...

    Anyone use Postini?

    If you use Postini, what are your thoughts? Spam/virus blocking rate? False positives rate? If you use a different service, I'd like to hear about whatever you use, as well as if you compared services against each other in a live test. Not looking for do-it-yourself stuff here. We already...

    Problems with Cisco website?

    Haven't been able to get to it all morning. I can ping the IP for their site, and the wbsite resolves in DNS. I thought Websense was killing it at first, but I removed it from equation and still a no-go. One interesting thing is that I get a packet from their server with an incorrect checksum...

    Web filtering for the home

    My friend has recently asked me to network his home for him. He gave me an unlimited budget to work with (really, really, really big kid-in-a-candy-store grin), but of course I still want to give him the most for his money. Part of what he wants is a web filtering solution for his kids. He...

    Working LSASS (MS04-011) Win32 Exploit

    I just tested the exploit code for the LSASS vulnerability against an unpatched Windows XP Pro machine. It crashes the service successfully and initiates a shutdown timer. If you guys have unpatched systems, I'd suggest you patch 'em up at the first opportunity. They're already thinking a new...

    SSL VPN Concentrators

    Has anyone used Netscreen's (Neoteris's) offering? Anyone used Cisco 3000 series with the new 4.1 OS that supports SSL? I'm curious to see what people think about whatever product they use. If you've compared the Netscreen and Cisco with each other, what did you think? Thanks in advance.

    New worm spreading via ICQ

    This is a first. There's a new worm out there that is spreading via ICQ. It directs you to a link, where one of the IE and Windows exploits is used to drop a worm onto your system which then does some of the following things: 1) Collects financial data specific to a few sites (ie Wells Fargo...

    Troubleshooting Inverse-ARP on Frame-Relay

    I'm a little shady on this one...so hopefully some of you guys can help me out. If you need Inverse-ARP on a frame interface, and its not configured, what are the signs of the misconfiguration? Does the interface just not come up? Or will you encounter intermittent errors? Specifically the...

    Your take on Juniper acquiring Netscreen

    Juniper would be wise to not screw this up and leverage everything that Netscreen gives them. In my opinion, this gives them a great opportunity to expand out of the service provider arena. With Netscreen, they have some of the tools they need to move into the Large/Medium business area, big...
