When adding the line

post-up ethtool -K eth0 tx off

to /etc/network/interfaces at the bottom (replace eth0 with whatever is your Ethernet adapter name)

Speed should go back to normal

In Windows, you can disable “transmit checksum offloading” from the properties of the network adapter in device manager!

On my computer, the Realtek RTL8169/8110 NIC has that option (IPv4 Checksum offload) in the dropdown with values of either

Disabled
RX & TX enabled
RX Enabled
TX Enabled

So we probably want to chose RX enabled in a XEN DOM0
But to my surprise, although Windows reports a RealTek RTL8139C+ in the DOM0 Windows Vista, the above options are not available, what is avaialable is

Task Offload with 2 optiopns in the drop down (0- All Dissabled 1- Chksum , 2- Chksum & TCP_Segment), i chose the first

Now, i rebooted the machine (I am almost sure that is not requiered, i did it for other reasons), and downloaded the file that is downloading relativly slowly,

The issue is often the cable etc…

ifconfig (General data, see what number your eth adapter has, mine is eth0 on this PC)
ethtool -i eth0 (tells you what driver you are running)
ethtool eth0 | grep Speed (See what speed we are running on)
lspci -nn lists (Lists the hardware, your eithernet should start with Ethernet controller)
ethtool -s eth0 speed 1000 autoneg off (Force gigabit, if the cable can not support it, light should go out on the switch)

As if it was not enough that when i want to install Yahoo messenger, i have to look for a custom installation button and untick the Yahoo toolbar, now it asks me if i want to upgrade messenger, i restart firefox, and there it is, they installed it

Dear Yahoo, if i went out of my way to not install your toolbar, i certainly don’t want it to install without telling me when i upgrade, Does that make any sense to you, i understand it is getting hard with LIVE and GOOGLE eating out on your share, but that is also a reason why i don’t want your toolbar

Anyway, in firefox you can uninstall the toolbar from the add-ons menu, and for explorer, you will need to go to control panel, Programs (In vista and 7), than uninstall it.

NOTE: Not only does it install a toolbar, it also changes my front page to yahoo.com.

1- By Domain name, when you host people’s websites, you need to monitor there traffic, both Email and web, it may be worth mentioning that the only way this can be done is through log filres, he reason behind that is that HTTP and Email requests are pointed at IP addresses and Hostname (Domain name) is only available as data within the stream, something only parsed by the web server and the MTA (Mail transfer agent). Some software to analyze Log files exists and can give you the answers to Domain based network traffic.

2- By PORT, Ethernet card, and IP, For such uses i recomment IPTRAF for live monitoring, and ….

3- By Virtual machine in environments such as XEN, in that case you can use the ifconfig command to see every virtual adapter’s traffic usage.

I will come to this post with more soon.

NOTE, for windows network captures (packet sniffers), i have always used a windows utility called wireshark (previously etherial), Microsoft released a very similar utility called Microsoft Network Monitor 3.4 that is compatible with Windows XP and above, When i simply want a graph of usage, i have once used a utility that does the trick called bwmonitor that is for $25, but it does provide you with a 30 day testing period (There is certainly a different application that can do the job and most probably a free one too, i just used this because it was the first i found)

Yet, godaddy has it in reverse, if you visit http://www.godaddy.com/, you can clearly see the canonical page is set to to http://www.godaddy.com/Default.aspx, yet when searching for godaddy, google still displays http://www.godaddy.com/

The exact Canonical name meta tag is like this on the godaddy website

    <link rel="canonical" href="http://www.godaddy.com/Default.aspx"/>

My own explanation: It seems (i think) google has certain exceptions like the default index page, where google knows the names of the popular default index pages, and treats them as an exception .

I would love to hear everybody’s thoughts about this

Cheers, and have a nice weekend everyone.

0114 KOREA
See photo of the Conexant 878A
—————-
And the other has a
————-
Philips
SAA7130HL
RB3693.1 04
KSG05241
See photo of the Philips SAA7130HL
————
So, the real choice comes down to the following factors
Driver : Philips chip wins
The PC has Windows Vista, There is an open source driver available for the conexant chip, and a manufacturer driver (official) for the philips chip (That is now Trident).
——————
FPS : Same
Both support 30FPS
—————–
Resolution: Connexant wins
Philips chip: Display and Record Resolution: 640 x 480, 352 x 288, 320 x 240
Conexant chip: Supports up to 768 x 576 VGA resolution
————–
So if the open source driver works well with no memory leak, i will go with the connexant, if the driver gives me a hard time, i will switch to the philips

pecl install intl

resulted in

checking for icu-config… no
checking for location of ICU headers and libraries… not found

so to fix it i tried
apt-get install libicu38 libicu38-dbg

but still no luck

apt-get install libicu-dev

then

pecl install intl

Now the error has changed to

C++ preprocessor “/lib/cpp” fails sanity check

If i recall correctly, this means i don’t have G++

apt-get install g++

Now running
pecl install intl

returns

extension=intl.so needs to be added…

so i issue

echo extension=intl.so > /etc/php5/conf.d/intl.ini

now restart apache

/etc/init.d/apache2 restart

But an error states that there are now duplicate functions

So, i removed the idn.so and added the intl.iso and both functions seem to be working fine now !

If you have not installed file sharing while installing Debian lenny, you need to install them, the easiest way to do that is

run the command

aptitude

using the arrow keys and the enter key, expand “TASKS” then place the bar over File Server, then the plus sign to select it (Shift +), right after hit “g” then “g” on your keyboard to install them.

Once done, Download the following files and place them in /etc/samba/ replacing any existing files (Backup your own files)

wget http://www.linuxhowtodocs.com/samba_base.zip

unzip samba_base.zip -o -d /etc/samba

Now to adding users, from the following 3 commands, After the second and after the third command, you will be asked to chose a password for the user joe

useradd joe -m -G users
passwd joe
smbpasswd -a joe

Now with this out of the way, Edit the file /etc/samba/smb.conf

The following need to be edited

netbios name : Should become the name of the computer on the network, in windows, this is the machine’s name
hosts allow : If your network is like mine where PCs take IP addresses of the form 192.168.2.x, then this one should be 127. 192.168.2. where 127 is for the local machine, the following part of the IP is the part of the IP that prefixes the IP of all network machines that should be able to access this file server (usually you will change the 2 with a 0 or 1)
interfaces : 127.0.0.1/8 192.168.2.0/24, like above, if your IP subnet is not 192.168.2.x, change it here (usualy you will change the 2 with a 0 or 1)
remote announce : if your subnet does not start with 192.168.2. then change it to your own (usually you will change the 2 with a 0 or 1)
remote browse sync : if your subnet does not start with 192.168.2. then change it to your own (usualy you will change the 2 with a 0 or 1)

Now scroll down, you will see a sample folder, edit that to the folder you want to share, and copy it over and over again for any other folders that you want to share, You are done, now you should be able to open those folders from the network.

To begin with, if it is disk space you are looking for information about, the following command should display the useful disk usage information

df -h

If you want to know the size of all sub directories in a directory

Move to the directory containing the sub directories (if root, can take a long time)

du -sh *

Although i have no idea why, the change has instantly shown on all low cost registrars.
Sureley, the registrars that charge you $35 for a .COM bundled with the prestige of being there customer didn’t have to increase there prices.

Prices direct from Verisign have changed as follows

Verisign used to provide .COM to registrars at $6.86, now it is provided at $7.34, the .NET used to cost $4.23 and is not at $4.65

or if you like, this one is direct from Verisign “VeriSign announced that as of July 1, 2010, the registry fee for .com domain names will increase from $6.86 to $7.34 and that the registry fee for .net domain names will increase, from $4.23 to $4.65. ”

But low cost domain providers DID increase there prices, here are a couple of examples.

GoDaddy.com .com domains from $9.99 to $10.69 (7%)
GoDaddy.com .NET domains from $7.49 to $8.99 (20%)

vcheapdomains.com .COM domains from $7.99 to $8.49 (6.25%)
vcheapdomains.com .NET domains from $6.49 to $7.49 (15.4%)

Verisign increased there prices on October 1st 2008

A yearly increase in .COM and .NET prices is not surprising, as in 2008 the ICANN and Verisign revised agreement allows for Verisign to raise rates by 7% every year of their new contract and grants them a presumptive renewal of that contract.

So basically, in 2 years, Verisign can raise there prices by 14%, and no one can stop them.

Not long ago there were plans to take the .NET tld from verisign, but in court, big companies like IBM, Microsoft, and others testified that VeriSign is one of the most capable companies, and that the ICANN should renew the .NET contract, and so they did.

In any case, there is plenty of news about the new TLD system, and we will have to wait and see if any of the new TLDs will be of any real competition to the .COM and .NET
