I have a web request log with the following structure:
[ts, app, controller, action, method, url, elapsed]
I would like to see requests that are taking elapsed > 1000 grouped by app, controller and action, is this even possible with AWS CloudWatch?
I am working on a software that I need to test with different types of NAT, and I would like to set up a test environment I can reconfigure in different NAT modes.
I would like to have:
(a)---192.168.3.0/24[NAT] ---- 192.168.1.0/24 ---- [NAT]192.168.2.0/24---(c)
This layout would allow me to connect to devices from two NATed networks, that is what I need to perform some testing.
I have a server with Windows 2012 I would like to add two additional NICs ( a and b), but what software may I use to create those networks and the different types of NAT?
Other option, is to install Linux. Is still iptables the right tool for the job? Would it be possible to do what I want?
Cheers.
Which is the default connection backlog value for TCP in Windows? I have tried to find it but no luck.

Do load balancers remove the HTTP header indicated in the "Connection" header? As far as I know, headers indicated in the "Connection" header are not supposed to be populated further than the first hop.
Thanks.
We have a F5 Big-IP load balancer that handles the SSL, so the servers behind it get HTTPS rather than HTTP (SSL off loading). I don't have version handy, but in the login page I can see "Copyright 1996-2010", so I guess it is not latest version :)
How will that schema work with WS and WSS? Will the WSS handshake hit the load balancer, and then be forwarded as WS handshake to the web server?
Thanks.
I was just thinking and that idea came to my mind.
Let say I have hosts A and B inside my local area network. I have a Router, and a host C in the internet. I know that when initiating the connection, the source port is chosen randomly, but what happens if two hosts chose the same when initiating to the same host:port?
A:10123 -> C:80
B:10123 -> C:80
How would the router know which packets belongs to each one?
Cheers.
I have a Windows 2008 R2 Server that switchs off on his own. and it does not look like a hardware problem since I can see in the log how all services are stopped and after:

There is no UPS. It is not a virtual machine.
I have switched now from "Balanced" to "high performance" to see what happens.

Before the UserPnP event, there is an event from 4 hours before. All those "7036" are "the XXX service entered stopped state"
Probably it does not explain anything, but this is the UserPnp event:

I have read "Scalability: 1-way" in the specifications of a server. What does it means?
The server is :
HP ProLiant ML110 G6 TV X3430 2.40GHz 4-core 1P 1GB-U Non-hot Plug 250GB SATA LFF 300W PS
I have enabled in my Web.config the GZIP compression, and I'm glad that it automatically adds the HTTP header "Vary: Accept-Encoding".
The problem is that IIS is overwriting the "Vary:*" that ASP.NET returns by default.
The issue is that in POST calls, the "Vary" header has to be "*", because it means the response depends on things that are not in the URL or the HTTP headers... as far as I know. A POST call with a "Vary:Accept-Encoding" could be wrongly cached, am I right?
What I want to do is tell IIS to respect the previous "Vary" header if any.

I'm a software developer finishing a web application. The app uses the database "DB1" in my SQL Server 2008 "SQLServer_1".
I would like to create a limited user that the web app will use in its connection string. This users will be allow to execute a list of stored procedures, nothing else. So the user shouldn't be allowed to execute adhoc SQL or other stored procedures out of that list.
I have a little mess between "user" and "login", I don't really know where should I create the new "account".
Which are the steps I should follow?
Thanks in advance.
I have this problem with my IIS7:
C:\Users\vtortola.dk>%windir%\system32\inetsrv\appcmd.exe list site
ERROR ( message:Configuration error
Filename: redirection.config
Line Number: 0
Description: Cannot read configuration file due to insufficient permissions
. )
Every time I try to publish an ASP.NET app to my computer, I cannot use it because IIS cannot read the configuration file, and I don't know how to fix this problem.
I've found the file at C:\Windows\System32\inetsrv\config, and the permissions are for:
Is this correct? What might be wrong?
