Bandwidth limitations can be imposed by such programs in artificial ways. Under unix the ftpd demon can be fired up in two ways. For anon users it can be fired up as a lower priorty process and thus will run less often resulting in a lower load on the CPU,DISK and www server. For account users it can be run at another priority. There are a Number of ways to accomphish this. you can create a background process to renice the ftpd for anon usres. -- for more info email me at : joseph@joseph.dswnet.com Sr Sys.
