Hi! Could somebody tell me, what is difference between these two prio parameters in http://lartc.org/lartc.html#AEN2241 1) tc class add dev $DEV parent 1:1 classid 1:10 htb rate ${UPLINK}kbit burst 6k prio 1 ^^^^^^ AND 2) tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 match ip tos 0x10 0xff flowid 1:10

help(qt) states that: "ncp non-centrality parameter delta; currently except for rt(), only for abs(ncp) <= 37.62" so I would expect that calling qt with non-centrality parameter exceeding 37.62 should fail, instead e.g. calling > mapply(function(x) qt(p = 0.9, df = 55, ncp = x),35:45) gives: [1] 40.21448 41.35293 42.49164 43.68862 44.82945 45.97048 47.11170 48.25310 [9]

Hi! There is one thing I can''t do. In my country we have to pay for "foreign" internet. Local internet is cheap and fast, but foreign is slow and expensive. So I want do following: mark every packet with iptables, where --set-mark 1 for foreign internet, but --set-mark 2 for local internet next when I got all traffic marking, I need to assign traffic to users so I make

For a same configuration in which the default policy is drop and only one connection is accepted in rules, continuous pinging to devices will stop squarely in 4.0.15 as soon as a very basic firewall is enabled whereas in 4.4.26.1, pinging will still continue after the firewall is enabled. All tests are done with proper reboot of the unit3 where the firewall is applied: unit1 <---> eth4

I can ping the virtual Linux servers NetBIOS name and access a share. Perhaps someone can examine the attached named.conf file for errors and/or omissions. My virtual Linux server (172.17.60.6) has been configured as a WINS server, and a PDC. I am not, however, certain how to configure it as a DNS server beyond what is in the attached named.conf file. Here are the results of pinging the

Hello, I have just setup some ipfw rules to checkout some traffic to one of my boxes. I have three servers, only one of which has weird traffic. It is getting ping'd on a five minute interval from approx 3 to 8 different ip addresses within the same second. For example: May 3 20:20:03 gaspra kernel: ipfw: 65002 Deny ICMP:8.0 202.160.241.130 xxx.xxx.xxx.xxx in via dc0 May 3 20:20:13

Hi. The configuration script is at the bottom. My configuration looks similar to this: imq0 | 1:1 (12mbit) | 1:2 (10mbit) | 3:0 | 3:1 (256kbit) / \ 3:2 3:3 icmp (rest) both 3:2 and 3:3 have rate 1kbit ceil 256kbit Icmp bucklet have priority 1 (better), "rest" bucklet have prio 2 (worse) I tested the script with heavy download

Hello all! I've got a Fedora Core 3 box running Samba 3.0.8. It serves a variety of roles, including mail server and samba server. The mail server is quite fast, but the smb server generates lots and lots of TCP retransmissions (as seen in ethereal). The general consensus is that this is new in the last few weeks. One user has been reporting speed problems for some time, but no metrics were

Thanks Jean-Marc and Benjamin for the answers. One follow-up question. If I use a repacketizer as Jean-Marc suggested by combining two 60ms frames to form a 120ms frame, without extracting individual frames and using a new TOC, I would need to have a "de-packetizer" that does the exact opposite of repacketizer. De-packetizer would need to separate this 120ms frame into two 60ms frames

Hi Jean-Marc, A simpler question. How does opus_encode() generate packets of 20ms (SILK-only or Hybrid)? Concatenating two 10ms frames or doing it straight with just one 20ms frame?

hi all friends has tc filter an priority of rules , like iptables, let me explain it : with iptables, when the packet find a rule to go, it doesnt see the rest of rules, and how is the behavior of tc filter ?? see it : one packet from 10.10.10.1:2421 going to 11.11.11.1:110 what rule above it will be shaped ?? 1 ) tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src

Hey there guys. I have successful postfix + mysql + sagator + clamav + spamassassin + dovecot setup (it was a really crazy month full of tweaking :]) and the only thing i miss is some per maildir specific filtering. i decided to use sieve. everything is fine except that dovecot's deliver process doesn't see the actual .dovecot.sieve file with filtering rules in the root of a maildir.

I am using the script below to simulate a very high bandwidth connection.I find that I could not turn the bandwidth knob up to 100Mbit.I have had a look at this generally,but could not find an answer.any help would much appreciated as i have spent a lot of time on this and have not found any answers anywhere. In my test,I have four network cards and their rate are all 1000Mbps. my scripts:

Hello everybody, I''m new to Xen so forgive me if this is already well known issue. I''m using Ubuntu server 7.04 (feisty) with Xen 3.0.3 Everything works perfectly, apart from networking in NAT mode. With bridging it works, with NAT it works, well, quite strange. Namely, pings go through and name resolution works. But when I try to use anything substantial, then

Hi there, I would need some help with my configuration. I have tried a long time, but did not find my error. Thus I would really appreciate your help.

Hello everyone, Please excuse these basic questions but I am new to Linux and I am getting desperate for answers. We are running redhat linux and after many hours of investigation I am unable to get a certain ip rule and ip route command combination to work. These are the software versions installed.

I have a router with 3 network interfaces like in the following ASCII diagram below. All interfaces are 100mbit. There is tcp traffic being sent from net1 to net3 and from net2 to net3 and the tcp connections consume as much bandwidth as possible. There is a pfifo queue on the egress interface eth0 of the core router with a limit of 10 packets. net1 --> (eth1) router (eth0) -> net3

Is there a reason why opus_repacketier_cat is limited to 120ms packets? It seems 120ms frames can only be combination frames, that is, only constructed by combining smaller frames of the same config. If this is true, then why stop at 120ms and not support longer packets? Regards, -- Daniel. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I have a 12 channel PRI with SNOM 190's and asterisk CVS from January. Most calls are fine, all incoming calls are fine, but I am getting echo on a significant number of outgoing calls. The person on the other side hears a perfect call, but the SIPphone side gets to hear themselves. It happens 100% of the time to some numbers (outgoing only), and only sporadically to others. Has anyone

We're being ping-flooded by the Nachi worm, which probes subnets for systems to attack by sending 92-byte ping packets. Unfortunately, IPFW doesn't seem to have the ability to filter packets by length. Assuming that I stick with IPFW, what's the best way to stem the tide? --Brett Glass
