Any tool where I can test a web site with slow connectivity? E.g.:
A web server running at Location A
and from Location B want to test the web site hosted at location A with various speeds
How is the loading of the web site from location B at 256kbps, 512mbps etc..
I'm running Lucid Alpha 1. Installed it about two weeks ago. Until a few days ago, the wireless networking was the best I've witnessed on any o.s. However, after last Wednesday's updates, connectivity now lags about 10-30 seconds whenever I open any web-page or access the repositories via aptitude. Granted after it gets going, it's fine. I noticed this same behavior in 9.10. I tested my XP connection and found no problems. .

The connectiviy is pretty fast when I try and connect the same from fedora 8 machine but it very slow when I try and connect it from fedora 11 system. I have tried using TS client but even then it is pretty slow. I have also tried using an Nvidia 8400 graphic card and Nvidia 9600 on Fedora11 OS.
I have also tried using Fedora12 OS as well. Is there any thing specific I can check on Fedora11? Or do I need to do some thing on my windows 2003 machine?
As promised the finished (pretty much finished) wireless script can be downloaded here the wireless_script is a diagnostic tool for wireless issues. It will return all relevant information to help diagnose a wireless connectivity problem, return connectivity stats and attempt to fix common problems such as blocks. It comes in cli - wireless_script_1.2.sh or gui - wireless_script_zenity_1.2.sh'
Let me know any issues you have with it. My contact details are in the readme.txt (also the wireless results.txt generated by running the script includes code tags for forums - so please copy and paste the whole document when pasting on forums to enable this function)
Wife's laptop has AR5001 Wireless Adapter laptop model is Toshiba Satellite A215
Problem : Wireless networking randomly loses connectivity and can not regain connectivity, the only apparent solution is a full power down , this is not even certain to work. The card works under Windows, she hates Windows. (I love her for this) I know it's not faulty hardware , because it will work for days on end under Windows without problems.
Things I've tried : madwifi drivers (any and all versions available) : These increase stability of the signal and seem to delay the inevitable however it still happens. When using these drivers the only option is to unload them modprobe -r then reboot then remove them again and re add them. It makes no sense why this works, and if I don't remove them prior to rebooting it will not work.
ATH5K drivers : These are pretty much junk, results are unpredictable at best, sometimes it will work perfectly for a few hours, sometimes it will not work at all. Nothing is repeatable, I can't seem to force whatever condition is causing this. rfkill does not show the wifi being blocked (hard or soft), unblocking it anyway does nothing, only way to make this work and it's iffy is to fully power down wait 5-10 minutes turn it back on and it MAY decide to work.
Firmware update : Updated the Toshiba BIOS to the latest version of the firmware 2.0 no joy here either. Same issue both sets of drivers.
Tried different distros and kernels : I've tried Mint 9, 10 ,11 ; Ubuntu 10.10, 10.04 , 9.10 and 11.04 (which is currently installed) , Fedora and OpenSUSE. All are giving the same problems. I have also tried a slew of different kernels no joy from any of them (I'm not at the computer with the issue now I will post exactly what kernel versions I've used when I have access to the machine).
Another useful bit of information, the hard switch to disable/enable wifi WILL disable it but turning it back on does absolutely nothing. The hotkey does nothing at all. The bios does not have an option to disable or enable the wireless card.
I will also post the typical lsmod , lspci , iwconfig all that good stuff when I get back to the computer in question. I'm probably just going to buy a PC card for it and give up on that one, but this is driving me insane and I would really like to see it resolved even if I do replace the hardware.
I'm learning via baptism by fire method here, and need to test PHP connectivity to a local postgresql 8.3.9 setup. (CentOS 5.5 x86_64). I have got PHP and Postgres both working; I can pull up a test PHP page via web browser, and I can login to postgres via the command line. What I can't figure out is how to test PHP connectivity to the local DB.
I found this test script:
Code:
<?php
$conn = pg_connect ('dbname=template1');
?>
Which I've named, testdb.php - when I run ./testdb.php from the CLI though, I get:
Code:
./testdb.php: line 2: ?php: No such file or directory
./testdb.php: line 3: syntax error near unexpected token '"dbname=template1"'
./testdb.php: line 3: `$database=pg_connect ("dbname=template1");'
I've seen a LOT of pages describing the internal code of the PHP file, but as a newb to this, I don't know how to execute this test. I've ran chmod 755 against the file to verify permissions, but this didnt effect the results. I've also done a "chmod +x testdb.php"
Code:
PHP 5.1.6 (cli) (built: Mar 31 2010 02:39:17)
I realized I wasn't doing this:
Code:
php testdb.php
but when I do, I get this error message now:
"PHP Fatal error: Call to undefined function pg_connect() in /var/www/html/testdb.php on line 3"

Well someone has been putting up this attack on my game-server ports. For those of you who don't know what type of attack this is, so its an attack which is actually masked to us because the attacker uses his machine to send packets to a machine called source which reflects the packets to destination. Based on this, the UDP port under Flood at the destination starts making outgoing connections to that IP and gets rejected which uses up more than 5mb/second bandwidth instantly.
I've worked out on some security for this and now need a tool to test this against my machine. I've used PentBox but that's not really powerful to do anything. As I search Google, I find something called Trinoo but can't download or test it.
I've been looking for a good data integrity test tool for linux, but I'm having trouble finding one. Basically I'm looking for an application that will generate a heavy I/O load to a raw device and then perform some kind of data verification on the device. I my case the raw device will be md raid5 array.
View 1 Replies View RelatedTwo part question:
1. what tools are recommended for designing web pages?
2. What tool sets are recommended for maintaining them?
I suspect that the first question really addresses the second rather than the literal question because of the source of the request. Here's the environment. A small church wants to post and maintain a website. Various non-tech persons will be responsible for maintaining much of
the content of the site. This tells me that they want/need a site that contains the necessary content maintenance tools within the site itself, not a tool on the individual desktops with the only real need for the design/dev tools being for initial construction of the site and a GOOD book on site design to guide construction of the site in the first place.
As part of my testing, I need to find a tool that will write/read IO to a volume. I need it to fill the volume and then read and verify that the write was successful. hroughput stats would be a plus, but right now, IO verification is a must.I need the volume to write, read, verify, then repeat until the volume is full.Can anyone point me to a free tool that can manage this?

View 3 Replies View RelatedI'm having difficulty accessing http://egrants.ed.state.pa.us/v2/default.asp while using Ubuntu 11.04 and Ubuntu 10.04.I've tried chrome, firefox and opera as well as three different ISPs. My Windows machines don't seem to have this problem.
A little background:My agency has several offices, some with different ISPs, but with essentially the same setup: ISP router/modem --> Ubuntu Server with Squid/Dansguardian --> Switches, etc.When we first started encountering this problem I thought I had to have had something going on with Squid/IP Tables or something of that sort. I connect my laptop (running Ubuntu 11.04) directly the ISPs modem/router and have the same slowness. I figure that maybe the site is having problems. I ask the other tech in my office to try it out (he's running Windows 7) and he has no slowness with the site when connected directly to the ISPs modem/router.For the time being I've circumvented the filter box for the Windows users who need access to this site, but I'm not certain that's the best solution.I contacted the site's tech support several times and just gotten a "we'll call you back".Any suggestions on things I can check/change with my setup to get this working?
I am having problems with website load speeds. I have fendora 15 and windows loaded on my machine. When I am in windows the internet connection is fine but when I am in fedora everything is slow. I am connecting wirelessly to a netgear router using a D-Link DWA-552 XtremeN Desktop Adapter
I have not installed anything for the wireless card.
I have tested my speeds from here [url] and I know that I am getting around 7000kb down.
I have gone into firefox to about:config and set network.dns.disableIPv6 to true... but everything is slow.
I just installed FC14 on 2 different PCs. It takes over 40 seconds for either of them to open some webpages, ie amazons home page. It is not my internet connection. I can open the same webpage on both my Windows PCs in less than 5 seconds. I was using FC9 up until 1 month ago, and I believe it took about 15 seconds to open amazon, but I never actually timed it. I spend many hours a day on the internet and have used FC for many years. I have been very happy with it. Until now. My PCs are 1.8GHZ single processor and 2.4GHZ dual processor. Do I have to revert back to FC9 to fix this, or use a different distro?
View 4 Replies View RelatedI have a server with two ethernet ports. I configured eth0 to be static, set at 10.1.10.148. I plugged in another router into the other ethernet port in order to configure that router. I configured eth1 to use dhcp. Using /etc/network/interfaces rather than gnome network manager. When I did this, I lost internet connectivity (internet routes through eth0 of course)
- Why did I lose internet connectivity?
In order to recover internet activity, I had to disconnect the new router on eth1 of course, and do sudo ifdown eth1. That wasn't enough however. After rebooting numerous times and pulling out my hair, I finally tried configuring eth0 as dhcp, rather than static, and this fixed the problem.
- Why didn't sudo ifdown eth1 solve the problem? What information was saved between reboots that somehow remembered that I plugged in the new router? Because my thinking was if /etc/network/interfaces was identical, and the network topology was identical, after a reboot everything should be restored, but it wasn't.
How can i check my FTP is working properly or not? or check out this connectivity?

View 3 Replies View RelatedI use a laptop with a built-in WiFi card (Intel PRO/Wireless 3945ABG [Golan] using iwl3945 module). It's OK but sometimes is not very stable, occasionaly it simply dies and I have to reboot. It was even worse but I improved it by applying a new driver.I also have a very nice USB WiFi card (D-Link System DWA-140 802.11n Adapter [ralink rt2870]). It's much better and faster.
So the problem is that in Ubuntu 9.10 (2.6.31) I can use only the built-in one. The other one (D-Link) also works but I can't make it connect to my router. The built-in card connects to it but the D-Link even does not list it among possible connections (but it lists other possible connections which I do not want to use).The funny bit is that this problem disappears when I use an old Kernel (2.6.28-18 ) : both cards work fine and can connect to the router at the same time (obtaining different ip's). I then disable the built-in one and happily use the external card.
Unfortunately the old Kernel has issues with sound and video, so I would like to use the latest Kernel with the external card. I tried WICD but it didn't change anything.I can add that under the old Kernel the USB card is used as a ra0 device while the new Kernel lists it as wlan1.
I have an issue with my Dlink DWA 547 802.11n PCI adapter, I'm under LUCID fully updated.I have no trouble connecting to any wireless but after a few minutes I'm loosing the connectivity strenght (getting ping reply from my router that vary from 2ms to 200ms). But as soon as I'm rescanning the network using the command (sudo iwlist wlan0 scan) everything is fine (constant 1-2ms ping). I'm using wicd as network manager. I have tried to schedule a job in crontab to launch every 10min a network scan command, but didn't succeed to have it working, morehover I don't think that's the good way.
View 2 Replies View RelatedThe goal: ipv6 connectivity using 6to4 The problem: no connectivity on some internal hosts (mixed win & debian) and no ipv6-web access on any host. Let's start with my external box. It is headless debian lenny dhcp/local-dns & cache/firewall. It has the following interfaces after a reboot:

My understanding is that ipv6 will auto-configure itself and that the radvd file is all that is needed by the external host to give all the ipv6 enabled internal hosts ipv6 web access. My question: How is my external host misconfigured? Or are the problems specific to the internal hosts? I am assuming that I have issues on both the external and internal hosts since some of the internals have golobal ipv6 address and some don't. I do however wish to address the external host first.
I am installing fc12 in a datacenter that does not yet support fc12. I have fc12 successfully running on several other machines in a different unmanaged datacenter. Here is my problem. After booting the machine I run a data transfer intensive operation. I use scp to transfer a 1GB file. After some percentage, 10 to 30, the network appears to go away. No ping, ssh, traceroute, etc are successful (in or out). At the KVM console I can check the status of the network service, it indicates its up. Restarting network, turning off iptables, ifdown/ifup do not have any effect. Only a system reboot will temporarily allow network connectionifconfig show LOTS of RX errors and dropped packets.

I am working on a project to build an embedded board with WIFI connectivity. My present status:
- I have a embedded development board TS7200 .
- It has USB and Ethernet Port.
- I am able to get port Linux on it and run program to communicate between devices and a computer using socket programming and Ethernet.
I need help in deciding how to get WIFI connectivity to the board. I guess it would mostly be using WIFI dongle? Any suggestion for a WIFI dongle?How should I get it working? Where should I look for proper reading material? I am am planning to do some basic program practice using WIFI on my laptop. How can I do that ?
I have a Fedora Linux machine and a Windows XP machine and I want to enable TCP/IP connection between them using a cross-over cable. I have a type of middleware server running on the linux machine and I want to be able to run the client for the application on the windows machine and work that way. I have heard Samba as a solution but my understanding is SAMBA is mainly for file sharing.. and is not necessary for establishing TCP/IP connectivity. Is this a correct statement? How can I go about setting up TCP/IP connectivity between the two machines?
