I'm a bit confused, so i hope i will not make too many mistakes. I'm using by some weeks, look at list archive, ifb to handle income traffic, mimic what i do by some years, eg htb more or less like ''wondershaper'' example script. On the same time, all my users go to internet by the way of a squid proxy, with c-icap as ICAP module, so files tend to be downloaded by squid, scanned and then server to clients. Also, i've enabled the ''poor's man WSUS'', eg ignoring ''partial content'' request to microsoft update sites. After enabling ifb/htb/sfq for ingress, i've found that works, but because fo the control and the fairness added, some trouble arises. Example: 1) i was upgrading a CentOS server (normally i use debian, but...) and yum have a default timeout on download too little, so they stared to download a file, proxy start the download but pass too little data, yum timeout and pass over a next mirror, proxy start the download but pass too little data... After some minutes, bandwidth hog occurred (http still have ceil at 100% of the bandwidth). 2) i was doing some test on a W7 box (normally, i still use XPsp3), and probably w7 update are a bit more ''aggressive'' then xp one; again, after some time bandwidth hog occurred. Clearly, i can tackle some parameters (eg, the amount of data c-icap/squid send while waiting for the full file, to prevent timeout; or stop to ignore ''partial content'', seems now even worst that honouring it), but i've a doubt: using a proxy, all the http connection came form an unique internal IP; this can confuse/prevent ''fairness'' of sfq, leading to worster performance and so, more frequent timeout? Apart the squid ''dumb'' confiuration, can i have missed something? Thanks. -- dott.
