Hi,
Hi,
When I have dowloads running, using my full internet pipe, which is just 1 mbit/s ADSL via dedicated router, DNS queries fail, meaning that anything internet related fails, in the entire house. It does not matter what machine is doing the download.
Aparently, the router is not capable of prioritizing and doing two things at the same time, like doing a download, and querying upstream DNSs.
You're lucky. My router simply ignores DNS requests even though it is configured as a DNS server by the ISP...
What would be the best strategy to at least paliate this? Maybe I should tell my machine to query some other DNS server outside, instead, in case it is just the router which can not do two things, but it may allow packages to go in or out... :-?
There was a script some years ago that configured the IP stack for traffic shaping, named wondershaper or something like that, that would reduce the throughput when sending and set traffic priority accordingly, so that the router does not choke and delay low-latency traffic, such as the DNS requests. There's also shorewall, which allows you to configure QoS in many aspects, but I don't know how much effect this may have if the router does not support QoS. Essentially, you'll have to configure traffic priority on another computer and maintain low enough throughput, so that the router simply forwards all the packets it receives without queuing them. Of course, you could also configure the programs that upload data not to saturate the bandwidth, if possible at all. -- Regards, Peter -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
