Update on Xubuntu livecd: Internet Bugs 2013-07-20 22:27
After a quite time I tried to remake the Ubuntu Linux Live CD according to the guide I posted before. After some digging I finally noticed the file /etc/resolf.conf didn't get created after livecd booted up.
As in the picture above, /etc/resolv.conf gets recreated by typing sudo dhclient eth0 in the console but some problems may still be there.
Reference on similar bug here:
Edit: This can fixed removing the /etc/resolv.conf if it exists before making the cd, and making a sym-linking in the chroot environment to other file as shown below.
ln -nsf ../run/resolvconf/resolv.conf /etc/resolv.conf

//get the file (e.g. image) and output it to the browser
$ch = curl_init(); //open curl handle
curl_setopt($ch, CURLOPT_URL, $_GET['url']); //set an url
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //do not output directly, use variable
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1); //do a binary transfer
curl_setopt($ch, CURLOPT_FAILONERROR, 1); //stop if an error occurred
$file=curl_exec($ch); //store the content in variable
//send out headers and output
header ("Content-Type: ".curl_getinfo($ch, CURLINFO_CONTENT_TYPE)."");
header ("Content-Length: ".curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD)."");
} else echo
'Curl error: ' . curl_error($ch);
curl_close($ch); //close curl handle
