RE: Need advice from the experts

I might have inadvertantly deleted your original email, therefore I copied Denis' response to reply to you :) I have to laugh at the title of your email. I am not laughing at you. I am laughing because I once had a Network General instructor who would begin the class by asking if there were

Re: Software Based Traffic Generator

For a pure packet blaster, you can use a tool such as the Sniffer and play back trace files. At my place of work, we use a tool called Smartbits by Netcom systems. It is a bit more sophisticated than just playing back a trace file, as it measures such characteristics such as latency and

Re: sniffer

Hi Jim, Try Surf Control. It is a very comprehensive package for Web Monitoring and can even (without being in-line) prevent users from going to specific sites (I think it sends a TCP RST to the client). It writes out to MSAccess databse format, so if the report you need is not there (I

RE: Conflicting answers

Flow control is a pretty broad term. Some could argue that this is a transport layer function but in actual practice and implementation the question is right. Bridges do not provide congestive feedback or flow control, but routers certainly can. Here is just some food for thought: The data

Re: Telnet vs Ping

There are probably access lists employed on the router (or intervening routers) that deny ICMP echo requests or replies. When you are telnet'd in, type show ip access-list or view the running configuration (show run). Tom Kager ___ UPDATED Posting Guidelines:

Re: Sysco cert question

I am currently in the process of studying for it. Some much less motivated colleagues say "Certification is worthless. What really matters is if you know how to do your job" or "I don't have time to study". I am pursuing this as it will lend further credibility to my resume and compliment (or

RE: Integrator wanted!

Respectfully, I agree. When I first saw this post and the signiature I was in disbelief? A CCNA and a CCDA should know this material. It irked me because I worked hard to become certified and prefer not to see my certifications turn into paper. I also felt that this was Edgar's chance to cut

Blocking access from geographic location on the Internet

Hi Everyone, I have a need to block access to an application by geographic location on the Internet...This would not likely be attempted through access lists, but probably through firewalling technology such as Firewall-1 1) Can the domain name extension of an address be an accurate

Re: Technical Question

Hi Bruce, Yes. It is possible to configure 2 NICs in the same PC. You can also multinet (assign both IPs to the same NIC without adding another physical NIC). Keep in mind though, that NetBIOS will only bind to one of these logical interfaces. From the description of what services you are

Re: TCP Methodology

Essentially IP is responsible for addressing the packet so that it conveys information about the location of the destination and therefore can be routed. TCP is responsible for establishing and maintaining reliable communications. This means that if TCP A sends data to TCP B and this data is

Re: What is Keepalives???

Brian, I Hope that this is not a longer answer than you wanted, but here it goes: From a generic sense, keepalive usually refers to a mechanism that ensures that an established "connection" or "session" is still alive. It is used at different levels in the OSI stack. Here are some examples:

Call for Action: Victim's of All in One CCIE Study Guide

Fellow Victims, As you may already know, Roosevelt Giles', All In One CCIE Study Guide is chock full of misstatements and inaccuracies, such as mislabeled diagrams, and outright inaccurate information. Where is an erratum? I could understand the publisher saying that they no longer work
