Hi I have the following very basic configuration for a delay pool on RH9 squid 2.6stable6-3. acl ttt 192.168.140.30 delay _access 1 allow ttt delay_parameters 1 25600/102400 The entries is in that order in the config file. What is strange is that I start with small values for delay_access, something like 500/1000. I then start to download a iso file in windows with firefox and keep an eye on the speed which is consistent with the settings. When I then increase these values and do a squid -k reconfigure the download speed increases steadily until it reaches the new limit. The strange part is that when I decrease these values again and do a squid -k reconfigure the download speed shown in firefox does not decrease at all. Am I missing something obvious or is this perhaps a problem with Firefox. I know using firefox to measure traffic is not the most scientific way but it works reasonably well. What I am trying to achieve is to limit our WSUS server downloads during the day with a delay pool. However everyone else must still be able to access the -- Groete Gerhardus Geldenhuis Registered Linux User #193352
