php - Image file permission - image resizer -

-

PHP mySQL

Hi, I have an interesting problem. I have a form in my CMS Allows to upload images to the server. The script transforms the images into a thumbnail (170px height) and a larger image (600px height). Thumbnail size is around 16000k and large images are approximately 160,000k in size. I do not set file permissions and just let it happen automatically when I go to the site I can see thumbnails but I can not see images of full size and I tracked this problem below on file permissions. There are RW-R-R permissions in thumbnails and RWs in larger pictures - - Permissions - that is, the public is not allowed to see large images. I save big images with the name of the original and I save the thumbnail with the thumbnail by adding the thumbnail to the end. Why do large images have different permissions, when they are uploaded and rewritten by the same script and when I do not set the file permissions? Does it have something to do? I get this problem when production uploads images to the server, not when working on my local machine. Thanks Andrew

How are you changing the size of the pictures? Are you using an external program?

This is just an estimate, but here

  1. an image uploaded by the administrator
  2. to upload the php script file upload.jpg rw- The image resizer program calls the php script to create image_thumbnail.jpg
  3. Image resizer writes image_thumbnail Jpg as rw-r-- Php script call image resizer program
  4. image resizer overwrites image.jpg, but without permissions Rw- (644)
  5. - --- (600)

Note that part to Ikshn is where it changes the image. Check Jpg to 600px, and then allow permissions for originally uploaded images. If they are 600, then your problem is.

However, a simple chmod will solve your problem.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
