Hi, i have a question if linux is able to do the same thing that commercial wan simulators do (which cost 7000 $ or more). Basicly i want to use the following setup. Linux Router Machine 192.168.0.1 192.168.1.1 Eth0 192.168.10.1 Eth5 192.168.2.1 Eth1 192.168.100.1 WEB Server. 192.168.3.1 Eth2

Hi guys, I''m running a freenas domU (FreeBSD 8.3 based, ZFS v28, 2 vcpus mapped to the same HT capable core) to serve storage for all purpose including other domUs running on the same host. I did some study to understand how well it works and the result is kind of confusing. In summary, the network performance between domains on the same host is worse than expected. And NFS service to

Hi, I am testing tinc for a very large scale deployment. I am using tinc-1.1 for testing. test results below are for tinc in switch mode. all other settings are default. test is performed in LAN env. 2 different hosts. I am getting only 24.6 Mbits/sec when tinc is used. without tinc on the same hosts/link I get 95 to 100 Mbits/sec using iperf.

I'm running rsync via ssh on two machines connected with 100 Mbit/s Ethernet cards (at high speed) via a Linksys switch. It's all right here in a single closet. I'm sending large files (initial transfer, nothing preexists on the destination machine) and seeing transfer rates in the 2 Mbit/s range. The CPUs on both machines are more than 90% idle, and I upped the --block-size to 256

Who mentioned fax? :-) Native CAPI isn't an option for us (unfortunately), as our service is a point-to-point service, which the AVM CAPI drivers don't support. We've now got another problem -- we're now able to make calls -- once. The kernel panics as soon as someone terminates a call (and, so it would seem, at various other times too). This has only been occuring since mISDN

I have a strange problem with VLANs with Xen 3.0.4. I signalled it on Xen-users list, but found no definitive solution to it. I configure VLANs so that they are available in dom0; domUs don''t know that they use VLANs. I use a stock "network-bridge" comming from Xen for setting up networking: #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge"

I''ve just uploaded 0.9.11-pre7. save/restore should be working for 32 bits on both SMP and UP, and maybe for 64 bits although it''s not tested. If someone could test migration it would be much appreciated. The installer seems to not install the drivers under 64 bit environment... but they can then be installed manually. Not sure why at this point.

Hopefully this is not too off topic. I have a server in which I'm creating an Exchange Information Store backup using ntbackup. The .bkf file it creates is 112GB. My goal was first to rsync it over to a local linux server, and then rsync just the changes over the internet to another linux server. I do this with other Exchange .bkf files (in the 4GB to 20GB range) and it seems to work well
