• Masquerade traffic from certain source IP to VPN connection

  - by Shuo Ran

  Network Setup: 10.0.0.1 Router: to internet 10.0.0.70 Server: Ubuntu based server,default gateway is 10.0.0.1 10.0.0.51 PC I created a PPTP connection(interface: ppp0) on Server to a machine on the internet, what I want to do is route all the traffic from certain IP address(10.0.0.51) through the PPTP connection and then to the internet. What I did are: Set the gateway on PC(10.0.0.51) as 10.0.0.70 Enabled ipv4 forward on 10,0,0,70 Add the masquerade rule to iptable: iptables -t nat -A POSTROUTING -o ppp0 -s 10.0.0.51 -j MASQUERADE After that, it seems none of the traffic from 10.0.0.51 be redirected to ppp0, instead these traffic are still going through 10.0.0.1 directly. Any thoughts on it?

• Xcode: iPhone screenshots no longer work

  - by Chris Newman

  I can't be sure when this stopped working because I haven't used it for a while, but it was possibly since I upgraded to the 3.2 SDK. In Organizer, when I select the "Screenshots" tab and press "Capture", nothing happens. I've tried this with three different devices and I've restarted my Mac. What's happened, and how can I fix it?

• Can't connect to web-server on local host behind NAT

  - by eyeinthebrick

  I got Ubuntu as host. I'm running a web-server on http://192.168.199.8:80. It is accessible from the local network, but when I'm trying to reach it by external IP, I go to my router's web-page. I arranged port forwarding on router for port 80 to my local IP 192.168.199.8. Unfortunately web-server is still unavailable via external IP. I checked whether the port is open via http://www.canyouseeme.org/. As it showed that the port is unavailable, I changed port used to 3659 (not forget to rearrange port forwarding rule). Although http://www.canyouseeme.org/ shows that port 3659 is open, I still can't reach my web-server. Where can the problem be?

• Retrieving Data in A NSTableView

  - by Heisennberg

  I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2). I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S Here's the code for the delegate : - (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { if ([[aTableColumn identifier] isEqualToString:@"value2"]) { [dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]]; } } Any idea ?

• IIS 7.5 Site being redirected from hostname to IP

  - by TuxOtaku

  So here's the problem. I have a site in IIS that is being redirected from the site's hostname to its IP address. The problem is, I haven't even set up redirects at all for the site; and yet when I analyze the headers that come through as the page loads, I see clear as day, "302 Temporary Redirect". What could be causing this? I thought perhaps it was something in my application's DB (it's a PHP/MySQL application), but I have ruled that out. I also thought that it might be a rewrite rule somewhere, so I deleted all my rewrite rules as well.

• PHP: Collect all variables passed to a function as array?

  - by Industrial

  Hi everybody, I was thinking about the possibility of accessing all the variables that are passed into an function, and merge them into an array. (Without passing variables into an array from the beginning) Pseudo-code: // Call function newFunction('one', 'two', 'three' ) ;// All values are interpreted as a one rray in some way // Function layout newFunction( ) { // $functionvariables = array( All passed variables) foreach ($functionvariable as $k => $v) { // Do stuff } }

• Centralizing / Abstracting MSSQL Data from Multiple Tables / Databases

  - by davemackey

  If one has a number of databases (due to separate application front-ends) that provide a complete picture - for example a CRM, accounting, and product database - what methods are available to centralize/abstract this data for easy reporting? Essentially, I'm wondering if there is a way to automatically pull data from multiple databases into a central repository that is continuously updated from the three databases and which can be used for reporting? I'm also open to alternative best practice suggestions?

• ModRewrite Domain

  - by Mike Knoop

  I've done a little research into ModRewrite rules and conditions but have not been able to find a satisfactory set of rules/conds which achieve the effect I'm looking for. Essentially, I have a directory on domain A (http://www.domaina.com/dir/) which I would like to redirect to a different directory on domain B (http://www.domainb.com/diff_dir/). Note that I only want to apply the rewrite rule if the user is attempting to access /dir/ on domaina. If they are accessing a different directory or root I do not want to rewrite the URL. Thank you!

• Does F# have an equivalent to Haskell's take?

  - by McMuttons

  In Haskell, there is a function "take n list" which returns the first n elements from a list. For example "sum (take 3 xs)" sums up the first three elements in the list xs. Does F# have an equivalent? I expected it to be one of the List-functions, but I can't spot anything that seems to match.

  Basically, I want to enter text into a text area, and then use them. For example variable1:variable2@variable3 variable1:variable2@variable3 variable1:variable2@variable3 I know I could use explode to make each line into an array, and then use a foreach loop to use each line separately, but how would I separate the three variables to use?

• Loop through Javascript array, print with string.

  - by Adam

  I have a simple array like: var myArr=["one","two","three"]; an I have a counting loop, which increases the value of var "i" by one. What I want to do is print the next value from the array each time the loop runs, next to a text string, like so: alert('value number '+myArr[i]+); But for some reason I can't get this to work. The following code works, so I'm assuming I'm not calling the counter right: alert('value number '+myArr[0]+);

• How to use enumeration types in C++? Apply within example.

  - by Sagistic

  I do not understand how to use enumeration types. I understand what they are, but I don't quite get their purpose. I have made a program that inputs three sides of a triangle and outputs whether or not they are isosceles, scalene, or equilateral. I'm suppose to incorporate the enumeration type somewhere, but don't get where and how to use them. Any help would be appreciated. // h8p466x1.cpp : Defines the entry point for the console application. // include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) { return 0; } include using namespace std; enum triangleType {scalene, isosceles, equilateral, noTriangle}; void triangleShape(double x, double y, double z); int main() { double x, y, z; cout << "Please enter the three sides of a triangle:" << endl; cout << "Enter side 1: "; cin >> x; cout << endl; cout << "Enter side 2: "; cin >> y; cout << endl; cout << "Enter side 3: "; cin >> z; cout << endl; triangleShape(x, y, z); return 0; } void triangleShape(double x, double y, double z) { if (((x+y) z) && ((x+z) y) && ((y+z) x)) { cout << "You have a triangle!" << endl; if (x == y && y == z) cout << "Your triangle is an equilateral" << endl; else if (x == y || x == z || y == z) cout << "Your triangle is an isosceles" << endl; else cout << "Your triangle is a scalene" << endl; } else if ((x+y) <= z || ((x+z) <= y) || ((y+z) <= x)) cout << "You do not have a triangle." << endl; }
