Hello, I have the following proplem. My DiffServ configuration is working fine when I do ping, but when I use mgen the packets are not detected at the core router. Here is my core router configuration: #!/bin/bash tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 set_tc_index tc filter add dev eth1 parent 1:0 protocol ip prio 1 tcindex mask 0xfc shift 2 tc qdisc add dev eth1 parent

Dear friends. I use ConstrOptim( ) and got error message "initial value not available". My understanding of "initial value not available" is that one of the following 3 cases happens: 1.The objective function is not well defined at the point of the initial value. 2. The differentiation of the objective function is not well defined at the point of the initial value. 3. The

Hey all, im experimenting with dovecot stats service, and graphing the result. My initial results are kind of interesting. Check out this graph showing connected sessions and users: http://grab.by/dReu At first I thought maybe one of our 35 imap servers was having issues sending data, but all individual servers show this patters. Here is a bunch of individual servers: http://grab.by/dReC

One of our summer interns has stayed on working part time on weekends during the school year.? This schedule presents an opportunity for technical investigations and some needed performance testing.? The last weekend assignment included data rate testing on one specific network pathway. Checking out previous network testing was the first assignment. Some five year old, archived SPARC/Solaris and

Hi, I''ve setup a Xen server host (suse, xen 3.0.2) with vlan as follows: server-eth0 <-> vlanXY <-> vbridgeXY <-> domU-eth0 That is: vlan''s are managed in the physical host (for better security). The setup is working, i.e. I can connect to/from domU-eth0 from hosts in the same vlan. The problem is: it seems I loose "many" packets.

Dear Friends. I found something very puzzling with constOptim(). When I change the parameters for ConstrOptim, the error messages do not seem to be consistent with each other: > constrOptim(c(0.5,0.3,0.5), f=fit.error, gr=fit.error.grr, ui=ui,ci=ci) Error in constrOptim(c(0.5, 0.3, 0.5), f = fit.error, gr = fit.error.grr, : initial value not feasible > constrOptim(c(0.5,0.9,0.5),

Hi, I have set up sth very similar to the example "efcbq" in TC. Here is my network setup: [Host1]---------eth0[router]eth1----------[Host2] I send udp traffic from Host1 to Host2, passing thru router. I run the efcbq code on dev eth1. After that, i run "tc -s qdisc". For each of the class (pfifo for EF; red for BE), there are parameters "drop" and

What is a good transfer rate to expect when writing from Windows XP/Vista to a samba network share in the following situation? * New client. Intel Core 2 Duo 6600 with 4GB memory, and Intel gigabit NIC. * New server. HP XW8400 with (currently) a single 5335 Xeon with 4GB memory, and integrated Intel gigabit. Running samba 3.0.25b, as included with CentOS (RHEL). * Netgear GS116 (gigabit)

Hi all, I need a little help, i am studing htb to control user bandwidth (download/upload) and I made a script as below to test. I am testing using ttcp tool from by linux box to other linux (192.168.200.51). my box <---- Linux = more than 128kbit mybot -----> Linux = get 128kbit But I want to control both ways, what am I missing? script: EXTIF=eth0 INTIF=eth1 TC=/sbin/tc DOWN=128

Greetings all, I am curious to know if either of these two sets of code is more efficient? Example1: ## t-test ## colA <- temp [ , j ] colB <- temp [ , k ] ttr <- t.test ( colA, colB, var.equal=TRUE) tt_pvalue [ i ] <- ttr$p.value or Example2: tt_pvalue [ i ] <- t.test ( temp[ , j ], temp[ , k ], var.equal=TRUE) ------------- I have three loops, i, j, k. One to test the all of

TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. My problem is: When I ping to P3.teql0 from P2 ("[P2]# ping 16.119.144.66"), the traffic can never go from P2.eth1, and all traffic only goes to P1.eth0. What P2.eth1 (16.119.144.33) did is broadcasting an ARP asking for the MAC address of 16.119.144.66, although I have specified the route to

I''m trying to get picture from ethloop and gnuplot. But the output seems weird. I still do not know why and want some examples.

TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. P1, P2 and P3 are three linux machines, and each has two network cards. P2 and P3 are connected in two ways: (1) directed connection between P2.eth0 and P3.eth0; (2) connection via P1. P1 acts as the gateway. TEQL is installed on P2 and P3 to load-balance packet transmission by round-robin sending packets

I'm trying to rsync a 8TB data folder containing squillions of small files and it's taking forever (i.e. weeks) to get anywhere. I'm assuming the slow bit is check-summing everything with a single CPU (even though it's on a 12-core server ;-( ) Is it possible to do something simple like scp the whole dir in one go so they're duplicates in the first instance, then get rsync to

Hi, I have been experimenting with linux bandwidth shaping through tc. Basically everything works fine, but because of the somewhat scarce and scattered documentation (I looked through the howto and the mailing list archives (and even in the kernel sources)) I still have some questions, probably like most of us ;-) What is the exact effect of setting a priority for a class? e.g. tc class

Hi, I have run into the following I bonded 6 NICs on my Cent OS server into a 600MB pipe. I use bond method 4 = dynamic Link aggregation. My Cysco Switch supports this apparently. However I only get increased bandwidth from my MAC by connecting via AFP. However when I connect via SMB I don't. I was told to change the sockect options to the following on my smb.conf file on my fileserver:

I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I would like to strip the DSCP and possibly replace it with normal ToS bits on egress traffic leaving my network. Leaving DSCP set is pointless, and could potentially cause problems with some ISPs that use DSCP internally I suppose. Setting ToS bits would seem ideal as most networks still honor it to varying

Last month Mark Williamson sent out a patch to unconditionally enable the trace buffer. I''d like to suggest that his patch be accepted and merged. I have performed some simple benchmarks to quantify the overhead associated with the trace buffer and calls, and found a negligable performance loss due to them. The actual number was .069%, and was gotten by timing a simple cpu-intensive

Hi: I am using a machine with the 2.4.26 kernel, and trying to compare the performance of the HTB qdisc with the HFSC one. I have the following simple script that allows me to have a video stream on port 1234 while it limits a ttcp UDP stream so that the video stream is unimpaired. #!/bin/bash tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1
