Turn off auto-sense for the media type for both cards. They may be trying to negotiate a speed and are failing. Although im pretty sure you would still get a link if it was physically connected.

Just a thought.

Boston_Bob

Yeah,

Ive read this and tried it. No luck, doesnt clear the registry entries that request the same IP the next time it goes to DHCP. I dont think Microsoft has any documentation on this issue and I was hoping someone had something unofficial or had played with the registry entries pertaining to ...

Hi guys,

I have a problem I kinda doubt anyone will have an answer for, but i thought I'd give it a shot anyway.

Here's the deal. At work I have a number of Windows 98 machines, all of them are having the following problem. It is all related to DHCP, but please keep in mind for business/political ...

This guy has ported OpenSSH to Win32 (Im assuming thats what you are using at work, if not SSH is native to most linux, *nix environments and will work on MAC OS X). You can set up the server at work and use any SSH client you like on your home machine, including ...

I dont know much about cable degrading (thats a new one to me) but as far as DSL goes the less stops, breaks, and outlets between your modem and your provider the better. Keep it away from flourecent lighting and other wiring too. Your best bet if you are experincing problems is to make sure you ...

set a rule on your router to forward requests on ports 6666-7000 to the internal IP of the server. Also known as port forwarding.

Boston_Bob

If you REALLY dont want your ISP tracking you then get a shell account somewhere that uses OpenSSH. Then tunnel all your traffic over an encrypted link using an SSH client to your shell account. It will act like an encrypted proxy. The only connections in your ISP's logs will be over port 22 to the ...

If you are going to connect this network to the internet you cannot use the 202.188.x.x addresses. These address are owned by "TMnet Telekom Malaysia". If you use them you will be effectively cutting that portion of the internet from ever communicating with your network. Not to mention if yor router ...

Boston_Bob

You dont HAVE to run a firewall.

However Ive seen far too many people who think they know how to set up their machine get hacked cuz they didnt. Now maybe this is because I work in a university environment, where things tend to be a little bit worse as far as computer tomfoolery.

A trojan doesnt ...

Boston_Bob

Well a T1 and DSL are different beasts. Im guessing you have a DSL at 1.5Mbit, which is the same speed as a T1, altrhough still not the same thing.

NT Server can act as a router for your purposes, I have never set it up with more than just a few static entries, so I cant really give you advice on ...

Hi,

I recently went to my parents house and found that AT&T had blocked many ports/applications from working over their network. I know this may not be news to you all, but I havent been on a residential connection in 5 years. (University's OC-3 aint too shabby :) ) Now I understand they dont want ...

packet sniffing is the act of reading data packets straight off the wire. Some network cards can be set in promiscuous mode, then it can read any traffic on the wire, not just traffic meant for it. Someone sniffing in promiscuous mode can therefore see what you are downloading/viewing/chatting/etc ...

Boston_Bob

Just so you know thats the same card I had the problems with.

Boston_Bob

What kind of NICs are in your machines? I have seen some lower end cards do some crazy stuff with autonegotiating the ethernet speed and duplex level (duplexity?? :) doesnt sound right :) ). Try setting the speed to all the same values starting with 10Mbit and moving up as far as it will let you. I ...

IIRC the BEFSR4.1 is not wireless, it has a 4 port switch. Unless the original poster just got the model number wrong, the post about WEP doesnt make much sense.

However to start diagnosing this, you have to make sure you are connected from the bottom up. Do you have link lights (the LEDs) on your ...

Boston_Bob

First, if you go to the school I'm sure they have a tech support desk. They can walk you through this. (Trust me, we have heard it all)

Second, if you're just staying there for a day or two (orientation/whatever) its most likely that you cant connect to their network unless your MAC has been ...

Boston_Bob

have you tried putting a sniffer on that interface to see if its trying to find something over your network? (dont know why it would...) Im not familiar with what the problem is, but Im interested in what it could be doing.

Take a look at http://www.ethereal.com .

Boston_Bob

if the URL starts with [url]https://[/url] instead of [url]http://[/url]
you are using SSL, it encrypts traffic so it cant be read if someone intercepts it.

I did not say that I know this is your problem but I have seen XP have issues with it. In combination with ICS these issues could be ...

Boston_Bob

Im sure your banking site uses SSL (if not you should dump them ASAP :) This might be the issue. Have you tried other sites with SSL?

I have seen problems with XP and connecting to some SSL sites, although I cant give you a reason or solution as I have not seen one myself. All I can say is that it ...

Boston_Bob

have you tried checking or replacing your cabling? sounds like a loose or bad cable.

Boston_Bob

sorry im not fast enough for you....

Tell you what, we'll trade, you do my programming homework and ill try to troubleshoot your networking problem from across the atlantic.

seeing that im taking the time to consider your problem and try to help you, a few manners seem to be in order. It is now ...

Boston_Bob

ok fair enough, i have never done any extra large captures with the Win32 version......thats what unix is for

Boston_Bob

by "real" i wasnt trying to imply that others were "fake" or that others werent "real", just that in my experience ethereal was a solid performing, well documented, well tested, reliable sniffer. I have heard not so good things about other Windows based sniffers listed in the above postings.

if we ...

Boston_Bob

I know someone else said this but if you want a real sniffer install ethereal. The windows port is very solid on Win2K, I dont know about XP.

Boston_Bob

ok,

i think i might have an idea of what is occuring, but unfortunately not an easy solution. It sounds like both of you are behind some sort of firewall that your respective ISP put in place. It lets outgoing traffic through but filters some incoming traffic. This is a very general statement, i ...

Boston_Bob

no worries, i didnt take anything the wrong way :)

you did get me thinking about some stuff though....the technolgies/languages you mentioned as being able to de-compile are all (with the exception of Java, can't forget the IBM jikes compiler, and several projects to turn Java into native machine ...

Boston_Bob

thanx for the link, that's perfect....i had done a search on msdn and google and that didnt find that page..oh well

Boston_Bob

Thank you for pointing out some of the finer points of what i was saying. I was just trying to keep my answer simple, Hamid doesn't seem like a programmer/hacker

I was just trying to get a point across in easy to grasp terms.

Boston_Bob

i see, i get it now, are those machines owned by the school? (that dont have restrictions)

also it sounds like they might have an application level firewall/filter running (example: even a proxy over port 80 failed, this is assuming it failed because the traffic was not pure HTTP) so what about ...

there is no *exact* way to "un-compile" or reverse engineer assembly code and get the original source.

It can be done to an extent, there are several tools which do this (names of which escape me at the moment) but the results you get back will not be the original source code. This lies in that ...

Boston_Bob

Hamid,

I think you may be using "resource code" and "source code" to mean the same thing in your questions. It is commonly (at least where i live) referred to as just source code.

Yes, most companies consider their source code to be company property and in some cases have patents on it. When you ...

Boston_Bob

are you both on @home?

did @home give you any other info? more details than just a "security" reason?

I've heard of them blocking certain ports before for residential users, but if the rest of the internet can see your server...? Is it just your friends IP thats blocked? Can you try other machines ...

Boston_Bob

getting 2 IPs is not going to speed up your connection over DSL at all. Over cable it could depending if your ISP caps you per IP (this is a hypothetical situation, i really dont know if any do this). Most likely it wont make a difference over cable either. Your speed is not determined by how many ...

Boston_Bob

Bill,

What was the purpose of arp spoofing? I know how this works but how did you think it was going to change the speed of your connection?

(not flaimbait, im just curious
