All,

I have a funny story to tell you, but I also have a question.

Yesterday, our e-mail server kept timing out, and our Internet  
connection was at a crawl for many hours of the day. I called  
SoverNet, our Internet provider, and I was told that we were using  
our entire bandwidth. This morning, same thing. I decided to  
download, and install ethereal on a windows box, and I started  
sniffing - yes, without reading the manual. While the program was  
sniffing, I got a call from [someone] in the district that has very  
few security restrictions because this [someone] can be trusted, and  
needs more access than other people. Anyhow, this person was needed  
help with something else in his/her room, which I fixed, but then  
said person said his/her computer was acting slow, and wondered if he/ 
she stopped a few downloads if it would speed up her computer. I took  
a look, and said person was downloading 28 large files at one time.  
We discussed what happens when too many large files are downloaded at  
one time, and that problem was resolved.

This is a funny story because I accidentally found the problem, but  
I'd like to know more about sniffing programs. The data that I got  
back from ethereal, out of the box didn't help me find the problem  
right away - I did only run it for a minute though just to play with  
it. Can anyone give me advice on reading ethereal data, or any other  
network sniffing solutions? Also, I installed ethereal on a regular  
PC box in my office - I'm guessing the box should be in front of our  
firewall to get better data, or maybe right behind it, as I wouldn't  
be able to see our internal IP addresses in front of it?

Thanks,
Bryan
