Delving into the AWS world, I have created two buckets in my AWS. The first one called BucketA (holding the files) and the second one called BucketB (holding the log files). BucketA will be hosting images which will be accessible from the outside world as these are not sensitive. Let's assume the images are called image1.png, image2.png, image3.png and the pattern continues.

Both my buckets are in the same region.

The web addresses for each file is as follows: (these are sample links and are not real and at the moment apparently someone owns them and they are in an access denied mode)

• https://s3.amazonaws.com/logging-bucket-444324324/image1.png
• https://s3.amazonaws.com/logging-bucket-444324324/image1.png
• https://s3.amazonaws.com/logging-bucket-444324324/image1.png

My goal is to accomplish the following: To know which IP address, at what time opened and viewed a certain image.

I have set the Log Delivery for S3 log delivery group in BucketB to read and write, and for BucketA I have enabled the Server access logging and set the Target Bucket to be BucketB.

Now, for testing purposes, I am trying to enter the links above, but I am not getting any logs written in the BucketB.

1. Can I accomplish what I am trying to accomplish by this method? (I Know I might use AWS CloudTrail with Data Events but I want to use good-old Server Logging)
2. Does this type of loggin work on basic link visit? Or it has to be done programmatically with a specific HTTP GET request so that a log appears?
3. Do I need to add any type of Bucket Policy or ACL than the ones automatically generated by allowing log access using the normal web console?
4. Does a request gets logged even if the access is denied to that object ?

There is a similar question here: S3 logs do not appear in targeted bucket which was solved by deleting all the buckets and creating new ones, which isn't really providing a solution to the problem and is the aws version of an IT saying Please restart the computer and it should work.

My mobile app will be serving images from my Ubuntu VPS.

Basically I have the images organized in a folder \DATA

What happens is, whenever an image is needed from the mobile application, a request comes to my back end, where it fetches the link of the image and sends it back to the user so that the link would open the image on the phone. For example, http://myexamplesite.com/Data/Image001.jpg

The images that I have are in sequential order. (Image001, Image002, Image003, etc).

What I want to achieve is, if someone finds the link http://myexamplesite.com/Data, and tries to access it via the browser, to deny him access. My goal is to make the images accessible only when it comes via a request from the mobile.

I am using Server version: Apache/2.4.18 (Ubuntu 16.04) Server built: 2016-07-14 T12:32:26 MySQL: V5.7

Is such a thing possible on Linux?

On a CentOS Linux 7.3.1611 I have VirtualMin installed. From the Edit Users on the left I have created a new user with FTP access not to use the root account everywhere.

However, whenever I try to login via winSCP using both FTP & SFTP, I get either a username password error (case of SFTP) or getting a connection error (case of FTP)

Is this a common issue and how can I fix it?

I have a 2 domain controllers.

The clients can login to the AD normally and everything works fine.

I want to accomplish the task of unifying all the Desktop Wallpaper Backgrounds of all the user and put the logo of the company. However it is not working.

Below is an image of how I am trying to accomplish the needed outcome:

Unfortunately, it is not working. Any ideas? Also, does it have to do anything with having a second domain controller? (which by the way, gets the users and groups replicated correctly)

I am trying to apply a scenario from the Cisco CCENT book where a 2811 Router uses VLANs. I have applied the network as is in the book inside my Packet Tracer.

Here is the section in the book and next is my implementation and the error I am getting.

//book example

Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname Corp
Corp(config)#enable secret myPassword
Corp(config)#interface vlan 1
Corp(config-if)#description myDescriptionIsAwesome1
Corp(config-if)#ip address 10.1.1.1 255.255.255.0
Corp(config-if)#no shutdown
Corp(config-if)#int f1/0
Corp(config-if)#description myDescriptionIsAwesome2
Corp(config-if)#no shutdown
Corp(config-if)#int f1/1
Corp(config-if)#description myDescriptionIsAwesome3
Corp(config-if)#no shut


//my implementation in Packet Tracer

Router#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname Corp
Corp(config)#enable secret myPassword
Corp(config)#interface vlan 1
Corp(config-if)#description myDescriptionIsAwesome1
Corp(config-if)#ip address 10.1.1.1 255.255.255.0
Corp(config-if)#no shutdown
Corp(config-if)#
%LINK-5-CHANGED: Interface Vlan1, changed state to up
int f1/0
%Invalid interface type and number
Corp(config)#

I get the %Invalid interface type and number error. What can be the reason? Is there anything I should add to the router after adding it in the packet tracer works space? Moreover, how do I create the Virtual Switch once I have set the router? Is it through the GUI or it is automatically done?

We have dedicated internet connection an our ISP has provided us with some real IP addresses.

We have several servers which we use, including a one that has a real IP on it as they enter to the server remotely from outside office and work.

Many people have suggested me that this is a bad idea as the server might be attacked and compromised given its public exposure via the real IP.

However, it is true that the IP is exposed, and maximum an attacker can do is reach the login screen and get stuck there as he does not have the password.

• What other things can go wrong while having a real IP on the server (Microsoft Server 2012)? and why usually it is a bad idea, (if it is at all)
• What are methods that I can use to enhance the security of the IP? (as low cost as possible)

I have 2 IPs on my Windows Server 2012. 1st is local the 2nd is real public.

Whenever I try to login using RDP from a windows 8 from inside the network of the local IP, I can easily log in. However, whenever I try using the public IP, I get the below error.

The server is on a domain and I am specifying the domain name as such NomainName\administrator

Things I have done till now:

added the ADMINISTRATOR account to the Remote Desktop Users built in group.
inside Control Panel\All Control Panel Items\System and under Remote Desktop Settings, the settings are turned on to allow remote connections.
The built in firewall is stopped (temporarily) to test if that is the issue.
The ANTIVIRUS KASPERSKY's firewall is stopped (temporarily) to test if that is the issue.

Any ideas?

One of my servers is shutting down randomly (we think power issue)

I am using the below command to get the dates of the shut down Get-EventLog System | Where-Object {$_.EventID -eq "1074" -or $_.EventID -eq "6008" -or $_.EventID -eq "1076"} | ft Machinename, TimeWritten, UserName, EventID, Message -AutoSize -Wrap

however I am looking for an internal or even a third party GUI app that gives me some user friendly data about the times and the reasons of shut down.
