iis ftp : Can I limit the network bandwidth for FTP (in IIS 5/6)?
Occassional, our users are using the FTP service to update some huge file
(e.g. 1GB) to my server, it consumed much of the network bandwidth (consume above 50% bandwidth in task manager) within my network. It did not only slow down the whole network during the upload moment but also can absolutely affect other users. I know that there is an option to limit the bandwidth for whole web site. However, I can't find any option to limit the bandwidth in FTP service. Any
Hi Bernard,
I've checked with the setting in IIS 5 as well, I also can't find any setting in IIS to control FTP bandwidth. Now my production web/ftp server is running IIS 6.0, do you mean that I can't do anything to avoid this concern if no available budget for me at that moment? Can you also introduce any third party solution? Thanks, Alan [quoted text, click to view] "Bernard" wrote:

You are better of with third party solution.
in IIS 5 I think you will have the control for http and ftp service. but then again, the throttling feature is not a good one. with IIS6. the ftp part has been removed. -- Regards, Bernard Cheah http://www.tryiis.com/ http://support.microsoft.com/ http://www.msmvps.com/bernard/ [quoted text, click to view] "Alan T" <AlanT@discussions.microsoft.com> wrote in message news:DB08C0DD-737D-40FB-99BF-7AA7B0841BD9@microsoft.com... > Occassional, our users are using the FTP service to update some huge file > (e.g. 1GB) to my server, it consumed much of the network bandwidth (consume > above 50% bandwidth in task manager) within my network.

Thanks for your information first!
In IIS 5, according to your message, right mouse computer name I just can limit the total no. of connection & connection timeout value in FTP Service Master Properties but not the bandwidth throttling inside WWW Service Master Properties. In additional, this throttling setting does not affect FTP service in IIS 6.0. Is that correct?

In IIS 5, I believed is at the master properties, right mouse computer name

Oops, I oversee this section in IIS 5.0.
:-p Hmm, in IIS 6.0, I think I've to find another workaround... Anyway, Thanks Bernard. Alan [quoted text, click to view] "Bernard" wrote:

Is there a free-of-charge replacement to a product "Attenuate II"
Some firewall or router allow you to control bandwidth... or you can google

Actually, I don't have any solid idea to limit the bandwidth in FTP service.
Perhaps I would like to check in detail my existing setting first as my server is running on NLB mode. Right now, I still don't confirm the reason of the high traffic when using FTP. It will take time to find the root cause of it. Alan [quoted text, click to view] "Bernard" wrote:

Yes, I'd checked the FTP log and believed the high traffic was caused by the
huge file was uploaded/downloaded by the users. And I'm quite sure such action is normal from client side. BTW, I'm using two servers connected to a network switch and the switch was then connected to the backbone of our network, I'm not sure whether this general "switch flooding" or just simply "huge file" issue. (As I know, switch flooding only affect all nodes attached to the same switch) Alan [quoted text, click to view] "Bernard" wrote:

You can look at the ftp log file ?
see if any illegal file was uploaded or huge file was downloaded by end users. -- Regards, Bernard Cheah http://www.tryiis.com/ http://support.microsoft.com/ http://www.msmvps.com/bernard/ [quoted text, click to view] "Alan T" <AlanT@discussions.microsoft.com> wrote in message news:45543996-3518-4689-AE3B-B05A1B01B331@microsoft.com... > Actually, I don't have any solid idea to limit the bandwidth in FTP service. > Perhaps I would like to check in detail my existing setting first as my > server is running on NLB mode.

Maybe, I'm not too sure on the switch flooding part.
since you have the ftp log file, you should be able to summarize the total in / out bandwidth and compare with the bandwidth report. See if it take up most of the bandwidth. -- Regards, Bernard Cheah http://www.tryiis.com/ http://support.microsoft.com/ http://www.msmvps.com/bernard/ [quoted text, click to view] "Alan T" <AlanT@discussions.microsoft.com> wrote in message
