How do you change MAC Address?

Ever wanted to get a permanent solution for your mac address change? Most of you who use internet via LAN has this problem of setting the mac address from the commandline. You do it every single time 3/4 console commands to get the net ready to use in your Ubuntu. Now go make a file(macset) at your home with any texteditor where u’ll have the following lines. notice 22:11:2F:3B:C5:54 is the Mac address of your LAN. It will vary upon your ISP/local provider. Just write down your own mac there. now do
sudo chmod 0777 macset

on the file and when you turn on your pc

you just type

sudo ./macset

to run your file’s commands as shell script, et voila! 🙂

ifconfig eth0 down
ifconfig eth0 hw ether 22:11:2F:3B:C5:54
ifconfig eth0 up
/etc/init.d/networking restart

You can now check if your MAC has been set properly by applying the follwing command at command line

ifconfig | grep HWaddr

An Alternative proxy script to host your WordprssBlog anywhere else

Months ago renowend PHP programmer Hasin Hayder posted a nifty thing of only 10 line proxy. Now this code had been written by Ferdous just after that post had been made. I am using this code to host my blog temporarily. But I felt the need for blogging about it which might help many programmers to better understand the technics. Definitely Hasin bhai’s technic is on the top. But we had a thought in mind that Regular Expressions are a bit costly and on a Conversation with him on Gtalk he said if you can make an alternative to this not using regular expression I am gonna treat you 😛  So, you know this is done for the challenge as well. 😀 Comparing the time of execution it yeilded a bit slower than Hasin bhai’s script. I have added the main proxy syntax highlighted here.

Remember, you need the .htaccess file with this to make it work. Go get the code from Hasin bhai’s original post 🙂

< ?php
    $primary_url=""; //original url of your wordpress blog
    $secondary_url=''; //here the new hosted url should be specified
    $path =array_keys($_GET);
    $data_url = (!empty($path[0]))?$primary_url."/".$path[0]:$primary_url;
    $doc=new domdocument('1.0','UTF-8');
    $data = $doc->saveHTML();
    foreach($tags as $tag){
        $href = $tag->getAttribute('href');
        $href_new = str_replace($primary_url, "$secondary_url", $href);
        $data = str_replace($href,$href_new,$data);

    foreach($form_tags as $tag){
        $action = $tag->getAttribute('action');
        $action_new = str_replace($primary_url, "$secondary_url", $action);
        $data = str_replace($action,$action_new,$data);
    echo $data;

Now Your .htaccess file need to have the following codes:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{QUERY_STRING} (.+)
RewriteRule ^(.*)$ index.php?$1&%{QUERY_STRING}

RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1

উপরের তালিকাটি দেখে প্রশ্ন জাগছে কেন বা কি? তাইনা?

তালিকাটি হচ্ছে, বাংলাদেশের সব পিএইচপি প্রোগ্রামারের, যারা পিএইচপি’র কোম্পানী(Zend) থেকে পরীক্ষা দিয়ে উত্তীর্ণ হয়েছেন, বিভিন্ন সময়ে। তালিকার সবার শেষে রয়েছে এই ব্লগেরই(প্রথম আলো এবং সামহোয়্যারইন  ব্লগ এ এটি পোস্ট করার জন্য লিখিত) কারিগরী নির্মাতা হাসিন হায়দারের নাম। তার মানে তিনিই প্রথম বাংলাদেশের ছেলে যে এই সার্টিফিকেট এনেছেন। এই সার্টিফিকেটটি এখন অনেক ডিমান্ডিং। দেখতেই পাচ্ছেন, মাত্র ওরা ১৫জন(পোস্টটি প্রথম রচনা করা হয় নভেম্বর ২০০৮, তখন ৬জন জেডসিই ছিলেন বাংলাদেশে) আছে তালিকায়। সুতরাং এখানে নাম লেখাতে পারলে আপনিও হয়ে যাবেন কেউ-কেটা। 🙂

ZCE কী?

Zend Certified Engineer. পিএইপি ভাষাটি প্রথম ডাচ নাগরিক Rasmus Lerdorf অবতারণা করেন। পরে ইজরাঈলী দুই ছাত্র Zeeve Suraski আর Andi Gutmans একে এর বর্তমান রূপ দেন তাদের নামানুসারে পিএইচপি কোম্পানি’র নাম হয়েছে জেন্ড। Continue reading
