Peter Stegnar's questions

I need to use SSL in a local network and I want to avoid browser invalid certificate error.

My idea is to generate self signed certificate and then use Certificate Pinning (HPKP) so to tell browser only this certificate can be trusted?

I currently explore all options related to this idea. I have tested with a self signed certificate and HPKP header (Public-Key-Pins) with value, like:

"pin-sha256="somedataencodedbase64=";pin-max-age=10;includeSubDomains"

Browser does not accept it as a secure. I still need to finish this test (with different self signed certificate and I need to make sure that SPKI is calculated properly ...

Now questions are:

• Are self signed certificate issued for given local host name (e.g. mylocalserver) and pinned in server response even valid? Will this even work?

• Does certificate pinning work for a local host names (this would mean, it only works with domain names)?

• Does pinned certificate have to firstly valid or thrusted by CA (this would mean self signed certificates can not be pinned - unless they are added to Trust Store on a client)?

• What would be the simplest another way to have a valid SSL locally, so I do not need to configure client (client Trust Store)?

• Can we seen certificate pinning as alternative of trusted CA? I read somewhere it is just additionally so this means certificate chain need to be valid first, then you can pin it?

• I also think more and more if this idea will even work. Because then we would see more use of this technique. Everyone would generate self signed certificate and just pin it ... And save few bucks on a CA trusted certificate ... Or what I am getting wrong or right about the whole concept?

How to mount Azure drive (attach disk) to the local windows? Does already exist some tool for this?

So use case is the following. I have a attached disk to the virtual machine in the azure. Now I would like to share this "attached disk" to my local windows. What is the simplest way to do it?

** I know there would be possibility to create local network thru VPN, and then "normally" share it. But lest say I am interested in even simpler option, because I would like that to access to this disk via multiple location.

How to determine a disk consuming service in Windows 2008 server? I have a problem on Windows 2008 server with a constant growing used disk space? How to determine which service consuming most of the disk? How to clean-up that disk? I have used Windows build-in program, "disk clean-up" but does not "find" those "growing" files? I am suspicions of the some logging service ... On the server is 40 GB disk, if I select all files on the C: disk and look properties, I get 12 GB (I have check option to see hidden files). Where are the difference? Where can I see the other 28 GB?

I would like to use all my monitors for the remote session (an option in RDC dialogue) if I connect (from Windows 7) to the one server with Windows 2008 R2 it works OK (I have remote connection on my all monitors) when do I connect to the another machine with Windows 7 it just wound not use all my monitors, but just one (full screen mode).

What do I missing here? Some setting on the Windows 7 RDP server?

Basically my question is:
How to establish multimonitor RDC connection from Windows 7 to another Windows 7 running computer?

I wonder what is the fastest and safest RAID combination for SATA drives and general use (some write, mostly read)?

RAID 0 is fast but utterly unsafe, RAID 1 is safe but slow, RAID 5 is safe but not so fast, especially on the cheap controllers (XOR calculations).

It seem that RAID 1+0 or RAID 10 is the best combination. You get mirroring for safety and striping for speed. Are there any other best or more optimal combinations? The only drawback of the RAID 10 is inefficient storage utilization.

I have phone 8 wire cable, shielded, with no pairs (wires go along to each other, no twisting).

I wonder if I can use this cable for wiring an Ethernet network?

Wires in the cable are in the following colors:

white green blue red brown grey orange yellow

I presume the problem with this cable is because the wires are not pair twisted and that's why to many interferences happen. Am I right?

UPDATE:

I have done some tests. I have connected very short cable (cca. 0,5m) and the network works fine at 1Gbps. I think the performance would dramatically decrease with the length of this cable, as I saw with 15m cable that is not working, router just blinking (as it try to establish the connection).

I would like to buy a 1000 Mb network switch and connect it with 100 Mb router which have DHCP server.

So I would like to know it computers connected on the 1Gb switch would be able to connect @ 1Gb network speed? I an not sure since DHCP server is 100 Mb, and it initialize the connection ... Would help if I would set manually IPs or this makes no difference?

I have problem with IIS and application pools. I have add a blank (with one test HTML file) web site with application pool. When I do a request to this web site in causes application pool of this site to stop. Why does the application pool stopping for each request?
This is happening with my ASP.NET application, so I decided to make a simple as possible test (this new basic web site with HTML file) and here is happening the same. Did I missed some setting? I am using a Windows Server 2008 R2. I have registered ASP.NET 2.0 framework to IIS.

I have installed some extensions:

• application warm up
• deployment extensions

I have a problem with delete, I would like to delete some folder which contains a number of files, and I am getting an error like:

Cannot delete Folder: The file name you specified is not valid or too long. Specify a different file name.

How on earth can I delete this? How to force to delete it?

I am using a VisualSVN. Today I have reinstall the OS (Win2003 R2) and then install VisualSVN on it. I have imported repositories, check access with browser, everythig looks fine.

After that I tried to update existing chekouts. If I try that I get:

Error: REPORT of '/svn/SomeRepo/!svn/vcc/default': Could not read chunk Error: size: Secure connection truncated (https://serverbase:8443)

On server (in event viewer) I get the following error:

Provider encountered an error while streaming a REPORT response.

But if I do a new chekout, then it work properly. How to "connect" existing chekout with server? I do not want to delete them an do new co, sience they may contain unchekined content.
