Solved X11 GUI not working in putty

I was having all kids of issues trying to get a RETS server admin GUI display up and running. It uses java and the first error I was receiving from the command line was

Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

I am sshing into the server with putty on Windows. The error above led me to download and install Xming. After downloading and installing I went to Putty > Connection > SSH > X11 > Click enable and set display location to 127.0.0.1:0.

Still no dice. It wasn’t getting any error in putty window, but learned if you right click putty window > Event Log will give you tons of information. I found this gem:

2013-11-03 17:20:26 Remote debug message: No xauth program; cannot forward with spoofing.

of course, xauth wasn’t installed. I ran the follow to install and had gui up in no time.


yum search xauth

yum install xorg-x11-xauth

Another thing to look at is your sshd_config make sure you have the following set X11Forwarding yes

Finding the Google Places Reference String

The illusive Reference String. A client needed to pull their reviews from google and after research I found out that I needed to use the getDetails() method to gather this information. Upon going to their API docs, I was left with this

This method takes a request, containing the desired Place’s reference value.

If only they told you how to get the value…ugh… After playing around with it, I found that the textSearch() method included this value in its response. I put together a client side script that uses a jQuery geocomplete plugin to get the lat/lng to pass the textSearch() method to retrieve the Reference String. You only need to know the address of place you are searching for.

I am not going to provide the script for it, but if you view source you can pull the appropriate code. ——> Find Google Places Reference String Now

How to add a favicon to Yahoo Store Checkout

If you want to add your own custom favicon to your store checkout then follow these 2 simple steps.

1. Upload your icon to the “files” section of your account and copy the https:// version. This way you won’t get a security warning at checkout. note: IE pretty much only accepts .ico and .jpg so if you are trying to tailor to the 12.1% market then you will want one of those extensions.

2. Then on each of your checkout pages you would put the following in the “HTML Head Section” note: I am using single page checkout, but all checkout pages need the code for it to show up on all pages of checkout

<link rel="icon" href="https://lib.store.yahoo.net/lib/youraccountnumber/icon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="https://lib.store.yahoo.net/lib/youraccountnumber/icon.ico" type="image/x-icon" />

1 2	<link rel="icon" href="https://lib.store.yahoo.net/lib/youraccountnumber/icon.ico" type="image/x-icon" /> <link rel="shortcut icon" href="https://lib.store.yahoo.net/lib/youraccountnumber/icon.ico" type="image/x-icon" />

You could also paste the two lines of code above into your “Head-tags” global variable in the store editor to have a favicon on call pages. Good Luck 🙂

Save remote image to server with PHP

I was working on a project where I was using an API to connect to Amazon to pull book details via ISBN. I needed to store the remote images on my server to be associated with the product that was being created and I put together these few lines of code to do so. It obviously will need to be reworked for your own needs, but the logic is below.

//Remove Image Url
$imageUrl = "http://www.removeimageurl.com/some/remote/image.jpg";
//Get File Extension
$extension = substr(strrchr($imageUrl,'.'),1);
//This is the name you will give the image
$name = $wholedata["name"];
//Remove all the junk from the $name
$match = array("/\s+/","/[^a-zA-Z0-9\-]/","/-+/","/^-+/","/-+$/");
$replace = array("-","","-","","");
$newName = preg_replace($match,$replace, $name);
$newFilename = strtolower($newName.'.'.$extension);
//New File name with new Extension
$extension = substr(strrchr($filename,'.'),1);
$new_file_name = strtolower('main_'.$newName.'.'.$extension);
//Put the remove file in current directory of server.
file_put_contents($new_file_name, file_get_contents($imageUrl));

//Remove Image Url

$imageUrl = "http://www.removeimageurl.com/some/remote/image.jpg";

//Get File Extension

$extension = substr(strrchr($imageUrl,'.'),1);

//This is the name you will give the image

$name = $wholedata["name"];

//Remove all the junk from the $name

$match = array("/\s+/","/[^a-zA-Z0-9\-]/","/-+/","/^-+/","/-+$/");

$replace = array("-","","-","","");

$newName = preg_replace($match,$replace, $name);

$newFilename = strtolower($newName.'.'.$extension);

//New File name with new Extension

$extension = substr(strrchr($filename,'.'),1);

$new_file_name = strtolower('main_'.$newName.'.'.$extension);

//Put the remove file in current directory of server.

file_put_contents($new_file_name, file_get_contents($imageUrl));

———————————————————————-
If you wanted to use directories on server you could (remove the last line above and) do something like

// Set server Path correctly
$saveDir = $_ENV["DOCUMENT_ROOT"]."/images/"; 
//Assign Write Privileges to Directory
chmod($saveDir,0777); 
//If chmod worked, and it is writable then write else fail
if(is_writable($saveDir)) {
    file_put_contents($saveDir . $new_file_nam, file_get_contents($imageUrl));
} else {
     exit("Failed to write to directory ".$saveDir);
}

// Set server Path correctly

$saveDir = $_ENV["DOCUMENT_ROOT"]."/images/";

//Assign Write Privileges to Directory

chmod($saveDir,0777);

//If chmod worked, and it is writable then write else fail

if(is_writable($saveDir)) {

file_put_contents($saveDir . $new_file_nam, file_get_contents($imageUrl));

} else {

exit("Failed to write to directory ".$saveDir);

}

This WordPress code tag BS is pissing me off and I will be finding a plugin to allow all this to be copied and pasted easily 🙂
