Estimados compañeros: tengo una duda sobre R; cuando ejecuto la prueba t, R calcula una t experimental y le calcula su probabilidad asociada y la compara con P=0.05 (valor por defecto). Mi duda es si para calcular este area, tipifica primera a z y luego entra en la tabla de z y la calcula y la presenta en pantalla. De otra manera no veo como asociar un valor de t a una probabilidad (la

...lows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq?

...:) If I set the burst/cburst parameter to, let''s say, 1500, the command "tc -s -d class show dev eth0" says that the value is 1499b/8 instead of the (correct?) 1500b/8.

I visited yesican.chsoft.biz and the author proposes a way to match packets by less than some size . Here is the thing: match u16 0x0000 0xffb0 at 2 With this match he says that packet with less than 80 bytes will match the rule. Well, 0xffb0 translates to 1111 1111 1011 0000 (which is -80 BTW). So, if I am correct any packet with bits 4 and/or 5 set (together with any of the 4

Hi All How to classify packets belonging to a FTP session? Port 21 session is easy. but what about data transfers? Their port numbers (both) are above 1024. I was thinking about ip_conntrack_ftp. Something like: iptables -A FORWARD -p tcp --sport 1024: --dport 1024: \ -m state --state ESTABLISHED,RELATED -j CLASSIFY --set-class X:Y But what if I also have ip_conntrack_irc, for instance.

...Of course it is big!, it''s my LAN class, limited to 90Mbit/s... Is there any better alternative to the above, given the great difference in rates and the fact that I won''t NEVER share bandwidth between 1:1 and 1:2?

Hello all, I got this problem while trying to shape traffic with iptables MARK and HTB. MARK: targinfosize 8 != 4 --set-mark gives "invalid argument" error message. Kernel version is 2.4.29 (some patches from patch o matic applied) Iptables version 1.3.4 Intel x86 architecture. I saw this problem discussed in a few places, but the discussions didn''t come to a conclusion

I want to stop shaping from running on my box, without rebooting it. What''s the best way to get rid of any tc rules? I have tried "tc qdisc del dev eth0 root" which appeared to be successful but traffic through my box is still very slow.

I have found a few bugs in tc, and have produced patches for them. Two require changes to tc, one to the kernel. Where should I post these patches? -- Regards, Russell Stuart

Hi, all: I''m involved in the study about the QoS,but have some problems , hope someone could help me answer: 1. Why most traffic shaping implement in the egress side (Uplink) rather than the ingress side(Dnlink)?(e.g. why put the police rule on the smaller bandwidth side but not put on the larger side) 2. I can''t differ the functionalities exactly

...ne doesn''t :? because in the output of "tc filter show" the only difference is that the first one matches "at 20" and the second one "at nexthdr+0", which should be identical :?????

...nd informative, it''s not enough (for me) to know how to solve this problem. I don''t want to use any other qdisc because I need a classful one and I don''t fully understand CBQ (I understand HTB MUCH better).

Hi there, yesterday I came across the "Vocera Communication Badge" and now I'd like to know if anyone here has played with that thing (or even just seen it in real life), and if a price tag can be found for this device? Too bad they don't use SIP... ;-( http://www.vocera.com/ http://www.heise.de/newsticker/data/tol-25.12.03-001/ Cheers, Philipp ** Wireless Specifications
