You could use Iperf (http://dast.nlanr.net/Projects/Iperf/), if your ISP agrees to install an Iperf server at his end of the connection. When we had a similar problem here, the ISP refused to do so. Since the ISP believed only readings from MS Windows/Linux (and not *BSD), we put a machine running Linux at our end, and by downloading large files with wget(1) from high bandwidth servers like `kernel.org', convinced them that we were not getting what we should have been.

Quoting Kiffin Gish [EMAIL PROTECTED]: I am having problems with a slow Internet DSL-connection, especially while surfing around the web. Try starting with bing and choose some points you can test from both in and out of your local network. Bing should be in the ports collection.

Unplug your router, plug in a PC to the adsl-modem. Set the PC to your router's external IP address, DNS, and gateway. Test the speed. (If your ISP won't provide a speed test, Google for DSL speed test and pick an appropriate one.) If you got your ISP to visit you, this is what they would do. They won't (and shouldn't) believe anything else. Your web sites will be down for less than 5 minutes. -gayn Bristol Systems Inc. 714/532-6776 www.bristolsystems.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Well - consider the fact while you run a few webservers, users browsing to those sites are only abable to access it by my above example, 128k. Now, imagine several users from the world accessing those same sites. Do you see where the issues are? Your provider may very well be telling you the truth. You may be saturating your pipe without even knowing it. -- Best regards, Chris It is morally wrong to allow suckers to keep their money. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
RE: Lousy network performance ...
Turn on SNMP on your router plugged into the adsl modem and use a tool like mrtg to graph the circuit utilization. Also, access your adsl modem's error counters and find out what your signal to noise ratio is, what your received decibel level is, if your taking errors, and such. Some of the consumer modems do not have these counters accessible and can only be queried via the DSLAM operator. Your service provider is right to push the problem back to you because it almost certainly is not their network. If it was their network you would notice a definite change at different time of days - if they are overloaded then at 4:00am you should get lightning speed. If your DSL sucks at that time then it's your problem, not their network. Unfortunately for you, however, your service provider didn't explain to you what you need to do to properly troubleshoot this. It could possibly be that you ASSUMED the problem was their network and pissed them off when you called in. I would suggest you call them again, politely, and ask, not demand, that they check signal levels and error counters on your phone line. If they can't do this then have them refer you to the telco that can. One other piece of advice for you, if your goal is to prove the ISP is wrong then you ought to just find another ISP. Your goal should be to find out the cause of the slowness, not in assessing blame. If your using a consumer ISP it is likely the first level tech support people probably cannot help you since their main job is helping people fix their misguided PC desktops, and they usually aren't even allowed to touch the back end equipment. But they can in fact hurt you badly by simply not passing you to the upper-level tech people who could help you. So, be nice to them.
