[-- Attachment #1 --] Hi! I was wondering if you know any reasons why my network might be slow (abnormally slow). Let me tell you about it. I have a FreeBSD server / firewall running. I have a cable modem that runs into the server. the server does its stuff and passes everything along to 2 computers hooked up to my internal network. When I connect my computer to the cable modem directly I get speeds up around 500 - 600 k/s but when its through the server speeds are drastically slower around 150 - 200 tops. Also, I have samba running, but that seems very slow too. If I run an MP3 off the server it is very choppy, however this seems to be local to the server alone. If I play MP3's or what not off the other computer on the network things are faster than ever. (d/l from the server seems the same way) All this leads me to the conclusion that something is wrong with the server. I don't know what, but let me explain how I have it set up. The server has 2 D-Link ethernet cards (I've had a good history with them...) in it. 1 connected to the cable modem the other to the internal network hub. All ethernet cards on the network are 10/100, but the hub is 10baseT (soon to be 10/100 as well). The server is set up for DHCPD from the outside, but I was having issues doing that internally so right now the internal IP's and stuff are all static. That is about all there is to it. Funny thing is I had the same setup (minus samba) running at school a few months ago and speeds were fantastic. Therefore I don't know if its the network cards, the hub, or some wacky configuration in the server itself. This problem existed before samba worked so I don't think that is the culprit at all. If you have any hints or experience with this please let me know. Thanks! -Mark [-- Attachment #2 --] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=iso-8859-1"> <META content="MSHTML 6.00.2716.2200" name=GENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=#ffffff> <DIV> <DIV><FONT face=Arial size=2>Hi!</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>I was wondering if you know any reasons why my network might be slow (abnormally slow).
