Does any one have any objections to (re)configuring the mailing list so that it sets the Reply-To header so that replies are directed back to the mailing list (as a discussion list)? For WHAT? Real MTAs have L byside R and G All in favor? Any one against? Yes. Sorry guys, but I have to support Michelle here and refrain that anyone not familiar with the Reply-To problem in the context of mailinglists do a quick google on Reply To munging. It's really just some ugly workaround for old/broken MUA to set Reply-To for a mailinglist pointing back to itself.

Re: [LARTC] QoS for VoIP
Hi Craig, I would like to prioritise all VoIP traffic on a linux router. I am new to QoS, tc and TOS, to please be gentle. My logic works like this: 1) identify the VoIP packets 2) mark packets using iptables (with TOS?) 3) use tc to prioritise the marked packets. Is this logic correct? If not, where is it flawed? it can work, VoIP for me is H323, for SIP i haven't checked yet what their ports are.. I understand that VoIP used the udp protocol and has packet sized less than 250 bytes. Is simply reducing the MTU on the interfaces good enough to give better thoughput, without the lag of larger packets trying to pass though? Well, reducing MTU is most probably not a good idea, as you force more packets benig sent even when you can keep the overhead to just 1 packet with large payload. so i wouldn't do that.. VoIP (speaking of H323) is UDP traffic on random ports but can be limited by using either GnomeMeeting or nmproxy (http://www.cryogenic.net/nmproxy.html), thouch i haven't tried the latter so far.. As of GnomeMeeting you can simply use a match for UDP ports 5000-5003 (on a direct connection)... For OhPhone and OpenMCU etc. the ports may vary.. If you don't use H245 tunneling there's also some TCP ports involved (for GM 3-30010). Using a GateKeeper will also have another port-range.. but checking either source, mailinglist or support info of these products will shed some light where you'll be most lucky matching their packets.. Are there any good HOWTOS? None that i know of, sorry.. Good luck! ;) -- Best regards, Kilian signature.asc Description: Dies ist ein digital signierter Nachrichtenteil
Re: R: [LARTC] time window in CBQ
Hi Steve, is 64kbit/sec enough for VoIP ? I would have thought not.. but I do not have VoIP... Steve, what voip codec do you use? If you can select, use G723 (6.3 kbit/s) yep, 64kBit is fine with GnomeMeeting. You should use Speex8k though, as there's a huge protocol overhead that needs to be added to that number of x.y kBit/s.. (many small packets) Empirically Speex8k works fine and MS-GSM might also do. The G.723 does require a hardware extension and is not available with pure software. Feel free to search the GnomeMeeting archives for details on configurations. ;) -- Best regards, Kilian signature.asc Description: Dies ist ein digital signierter Nachrichtenteil
Re: [LARTC] Cant restrict netmeeting traffic
Hi Joel, From 3 days i m trying to restrict Netmeeting traffic. I have restricted the bandwidth to 30kbit per ip. but the machine with netmeeting. means when we use netmeeting the traffic goes very high to 450. all others things are not taking more than 35 traffic but when using netmeeting it shows 450 upload traffic. what can i do to restrict this type of traffic. netmeeting using h323 protocol some like that protocol can any one suggest me how to restrict it. i guess your best bet is to use a GateKeeper to make NM use only a small band of RTP (UDP) ports.. you can define the RTP ports in the gatekeeper.ini and then shape them to your desired speed. The Linux equivalent of NM, GnomeMeeting has already the small RTP-range builting by default, so you could also use that, if you have the option to use Linux as workstation. it'll be a bit of work to get your gatekeeper (for win there's a DUAL gatekeeper iirc) up and running, but that's your best bet. -- Best regards, Kilian signature.asc Description: Dies ist ein digital signierter Nachrichtenteil
