Hi all, Here is my setup: Host1 ---> Router ----> Host2 When i run ttcp -t on Host1 while ttcp -r in Host2, the bandwidth that i can get is about 860 Kbytes/s, which is less than 7Mbps. But i am using NIC 10Mbps for all machines. Why is that so? Currently, i am experimenting with the example efcbq. I am using MGEN (a UDP traffic generator) to send 2 flows of traffic (EF and

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

Sooner or later everyone needs to install a package that is not included on the official installation CDs/DVD. Until now I just used rpmseek.com and Rpmfind.Net but of course this is far from optimal for security and compatibility to reasons. So what is the recommended way to get and install "non official" packages that are not part of the repository?! Thorsten

Hi Folks, I'd like to install cyrus-imapd 2.4 in CentOS6. Found rpm cyrus 2.4 for CentOS6 on rpmseek. cyrus-imapd-2.4.17-30.1.x86_64.rpm But there are conflicts with postfix 2.6.6. Can I ignore this conflicts or is there a suitable version of ppstfix available? Thx Timothy

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 don't read this list, so if anyone wants to respond could they please copy me so that I see what is happening. After several exchanges between myself, Marc Schwartz and Peter Dalgaard, we have come to the following conclusions: a) Shift-Return does not cause a segfault on most terminals, only Kde's Konsole. b) The bug is easily reproducable there. c) The "real"

Is there a reason why you need 2.4 vs. the 2.3 package from the CentOS6 repos?

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

Hallo Steff, mach dir keine Sorgen es wird nix gesperrt reduziert oder ?hnliches bei ?berschreitung xD Ich muss gleich einkaufen, Besorgungen machen f?r den Urlaub. Bin um 13:00 Uhr wieder da.

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

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

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

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

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.

Hi all, I have started the rsync in deamon mode. When I use the following command: rsync --port 9876 u018::treeA it seems to work fine but no files are copied from the server. Using rsync without the deamon works fine. I tried to debug it a little bit, but I am unable to figure out what's wrong. 337:david@u050 /export/treeA> rsync -r -vvv --port 9876 u018::treeA opening tcp

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 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:

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 Guys, I have experienced an issue when the smbd stops responding, and after cannot kill the process, using SIGTERM or SIGKILL. A reboot cured the problem. I had the same problem once again a couple of days later. I realised that both times I had changed my smb.conf file directly, using vi, and shortly before the hang occured. The changes to the file were very minor, and the two were

Using a default xen3.0.1 setup for dom0(rhel4 distro) and domUs (gentoo, rhel4, centos4.2 distros, ttylinux) with the domUs all having dhcp turned on, is there an easy way to tell from within the dom0 what ip addresses were assigned to the domUs after bootup?
