I need to test network card throughput and speed between two computers, one is running Fedora and other running Windows 7. Usually I would use netperf to perform this task, however I can't find Windows build of netperf. Can anyone recommend any network evaluation tool, similar to netperf (clien/server) which has both Windows and Linux versions.

I'm interested in testing the difference between using the proprietary ATI driver and the open source driver and also the performance under various distributions.
What's the best software to benchmark graphics cards?
I just got a graphics card ATI installed on my fedora 10. I would like to see the functioning of the same with some kind of game. Any suggestions for game under fedora 10 to see the graphics application.

You can try to start the mysqld daemon with:

and use the command line tool /home/mosty/mysql/bin/mysql to connect to the mysql database and look at the grant tables:

View 1 Replies View RelatedI have a 10.04 install with 2 network cards. wlan0, and eth0. wlan0 is the internet connection. eth0 is the local network. I want to be able to have internet connection sharing between eth0 and wlan0. I have set everything up, using firestarter.
is there a way of testing the eth0->wlan0 routing from the machine itself? The routing table looks sound, but I would like a quick way of confirming it. Is there a tool, like PING or TRACEROUTE which will let me say "ping [URL] going through eth0" ?

I have pc with two NIC's (eht0 and eth1). I want to test throughput switch/router.I can ping on both interfaces.Connection Diagram:
eth0 -> Patchcord -> testing devices -> Patchcord -> eth1
I run two iperf:
-s -B 192.168.1.10 (eth0)
-c 192.168.1.20 -B 192.168.1.20 (eth1)
Results:
[ 3] 0.0-10.0 sec 4.45 GBytes 3.82 Gbits/sec
The test results are false because I use 100Mb/s NIC's. I can't use two pc's for test.I tried to do the same test under windows 7 x64 it and works properly, but under windows xp there occurs the same problem like under ubuntu.
I'm running Ubuntu 10.04 Server. I can't get my Wireless Card & Wired Card to work at the same time. My interfaces file is incorrect, when I comment out 1 of the interfaces the other works. I have attached my interfaces file.

View 2 Replies View RelatedI've installed Ubuntu 10.10 on an old box to use as an office print/fax and file server. I tried the server edition but I had no chance with command line programming so I've just used normal Ubuntu.
Ubuntu itself is working fine and I've installed my HP Officejet printer and it's fully working on the Ubuntu box. SAMBA and CUPS are installed.
I've then added the printer onto my Vista machine and here's where the fun starts. The Vista box sees the printer on Ubuntu, adds it with no problem and happily prints test pages, but I can't get it printing anything else.
I can't for the life of me find any reason why it would print a test page, but not print from Word, adobe or even a browser.
I do not know much at all when it comes to setting up hardware--servers, switches, etc.
I have a 1701HG 2Wire wireless router that I use for my home network. I have an old pentium 3 tower that is just laying around, and I want to be able to host my projects on it for testing. Basically, I just want to be able to do everything on my laptop and then upload it to the server for testing.
I have set up an Ubuntu LAMP server on the desktop and am able to do everything I want via SFTP; however, I want to be able to type in "projectx.local" in a browser on my laptop to go to one test site, "projectz.local" to go to another, etc.
Is this possible, since I do not have the server set up as my gateway? It is merely connected to the router like everything else.
Set up a server with Bind, Dovecote, Apache etc. Registered a domain and made all the necessary things for it to work. The server can send/receive mail on my domain, but when I try to look up the site I have it returns a lookup failure. I know Apache is working as I can browse the site when I used my ip address but I can't when I use the domain name. Anyone got a few tricks I could try to dumb down and find the possible failures I did when setting this up?

I want to do this so that when my automatic backups run they actually go to the remote location or fail. Currently, if there is a network problem that prevents the network share from mounting, the files simply get copied to the folder (e.g. /media/backupmount) and end up filling up my small local hard drive.
View 3 Replies View RelatedBeen helping a user who recently upgraded to 11.04 as his networking stopped after the upgrade. One thing I noticed was that he could not get ping to work.Then checked my 11.04 machine and it also fails to ping using Network Tools. I know the network is OK as I am using my Ubuntu machine to write this. Ping from the command line is fine so it is only the Network Tools ping test that appears to be broken.
Asked another Ubuntu 11 user to check his machine and he also cannot get ping to work even though his machine appears to be fine. Again this is only using the GUI tool.I know it is not hardware as I can dual boot and in XP everything is fine and I can ping all my systems. Also I am sharing a folder from my Ubuntu and my Mac shares the folder just fine. The Mac can also ping everything except the Ubuntu box. Command line ping works so it is not a basic network problem.So as far as I can tell the Network Tools ping test is not working. Has anyone else seen this or can confirm that it is broke. How do I report this or get it fixed?
My current setup is a slack based distro with Squid 3.0 running in transparent mode with WCCP. Web filtering and AV scanning works great but we need to go a step further and introduce port filtering into the setup. I can easily accomplish this with iptable entries but only if I point to the proxy directly; the goal is to do this completely by interception. So far I've had no luck doing this with iptable entries or with squid ACL's and I am wondering if there's something that I am missing or just not doing correctly. So far during testing I've just been testing with common IM chat ports such as MSN and Yahoo. I am currently trying to setup a test lab with squid and 2 NICs with one NIC connected directly to the internet but this is not a route I would like to go.
View 1 Replies View RelatedI recently installed Xubuntu on my old P3 laptop (Compaq Armada E500 if anyone is familiar). The laptop is a bit old, so both wired and wireless networking is done via PCMCIA cards. I have 2 cards installed, one for each purpose. I can't find the dongle for the wired card right now, so I am trying to use the wireless card. I am able to find the network I want to connect to, and type in the password since the network is secured. It tries to connect but then pops up again asking for the password (I know it is correct). Is this card supported by linux/compatible? I tried finding drivers online but the sites that had drivers were down.
View 1 Replies View RelatedJust installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.
I succeeded in setting up a vnc server on a fedpra9 tested it locally and it was successfully connected but no connection done from other machine in the network , even though they can see each othervnc server is pingable se linux is disabled

View 4 Replies View RelatedI have Fedora 10 with 2 nic's and have used the firewall tool, network manager, etc.,then disabled the firewall front end and wrote my own iptables rules but can not even enable eth1 to use it. Tried 2 different common cards (like a network everywhere 10/100) Service network restart says eth1 not there.
Right now Ive:
eth0 connects direct to internet via my cable ISP.eth1 I've set as 192.168.1.1, netmask 255.255.255.0, gateway I wasn't sure but I set as my IP on eth0 isp supplied. DNS wasn't sure, just left blank.
But I can't even enable eth1 to test those settings.
then with gui firewall crap disabled I wrote my own iptables ruleset: (kernel flagged for ip forwarding)
with all chain policies set to allow.
Code:
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -j DROP
iptables -t nat -A POSTROUTING --out-interface eth0 -j MASQUERADE
iptables -A FORWARD --in-interface eth1 -j ACCEPT
And on the slackware box (ethernet switched btw) I set up static IP 192.168.1.100 w/ eth1 on fedora
as gateway.
But like I said, fedora refuses to enable eth1. Been reading and googling last night and all morn.
