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

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)

My thanks to all that responded to my posting about measuring network performance.? Helpful suggestions are always very much appreciated.? The type of testing that we were attempting does not appear to be a major topic of interest on the list but the additional information below may be helpful to some users. Initial reports of an issue with |dd not being recognized was questioned so several more

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''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.

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. 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 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

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.

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services.? This begged a question about why every computer would not have a radio module to receive time.? Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned

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

Hello all, I would like to introduce our group's new bioinformatics package to you: pathfindR <https://cran.r-project.org/package=pathfindR> This tool is designed to improve pathway enrichment analysis by firstly identifying active subnetworksin differential expression/methylation data using a protein-protein interaction network. It then performs pathway enrichment analysis

We have been fortunate to hang onto one of our summer interns for part time work on weekends during the current school year. One of the intern's jobs is to load documents and data which are then processed.? The documents are .txt, .docx, and .pdf files. The data files are raw sensor outputs usually captured using ADCs mostly with eight bit precision.? All files are loaded or moved from one
