• IPtables and Remote Desktop with Proxy

  - by Sebastian

  So I setup a windows 2008 web server R2 on VirtualBox. Currently using Bridged Network. I can remote desktop to the machine hosting the VM (10.0.0.183) but cannot remote desktop to the VM itself (10.0.0.195). The remote port on the VM set to 5003. VM setup to accept remote connections (windows side). We also use a proxy for our internet, and I added these rules under NAT. (centOS 5) on our proxy box. -A INPUT -p tcp --dport 3389 -j ACCEPT -A REROUTING -i ppp0 -p tcp --dport 3389 -j REDIRECT --to-port 5003 -A FORWARD -d 10.0.0.195 --dport 5003 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT I've been trying for hours and hours and just cannot get it to work. I also used freedns so that we can use a domain name to connect too this VM over the internet. (the DNS points to our external IP address). If we don't get this right we will have to purchase a PPoE from an ISP to connect to this VM remotely, but I know that there is an alternative route if I can just get this port forwarding right!

• Routing connections through VPN based on hostname (not IP range)

  - by Michal M

  This bugs me immensly. I need to connect to client's network through VPN. But I definitely do not want to send all the traffic through client's network so this option is out of question. What I need basically is for the OS to know that all client's network subdomains (*.example.com) need to go through the VPN connection. I tried a couple of options: Changing order of services and setting the VPN on top, but this works the same as "Send all traffic over VPN connection". Using "VPN on Demand" option from network advanced options, but this feature is quite rubbish to be honest. Seems to work only in Safari (?!) and it doesn't route the connection, but it basically triggers the OS to connect to the selected VPN. The reason I need it to work based on hostnames rather than IP range is simple - my client has a lot of servers inside his network and it's impossible for me to remember all IPs. They are all within a range, but this doesn't help me remembering. Another option would be to put the VPN connection on the bottom of network services and untick "Send all traffic..." and then put all known hostnames in hosts file, but considering there could be hundreds of servers (therefore hostnames and ips too) it ridiculous job. And if new server appears on the network I'd need to edit the hosts file again. Sisyphean labours. However this works on Windows very simply. If a hostname is not available through default network interface, then it seems to try VPN connection and this works brilliantly. So, how can I achieve that on Mac, then? I know client's internal DNS addresses if that is of any help (like directing a certain domains through a different DNS)? PS. Using latest version 10.6.6. PS2. I am using VPN to access intranet, version control servers (svn://), samba shares and for SSH access to servers.

• Dependency Properties Made Easy

  ok so I found that for some reason I thought I did a post on this before and I couldn't find it. So I thought I would make a new post as simple as possible. Here is a simple dp:public readonly DependencyProperty ResistanceProperty = DependencyProperty.Register("Resistance", typeof(double), typeof(AnimatingPanelBase), null);public double Resistance{get{return (double)GetValue(ResistanceProperty);}set{SetValue(ResistanceProperty, value);}}Nice and simple right? why bother you ask, well the biggest...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Synchronized Property Changes (Part 4)

  - by Geertjan

  The next step is to activate the undo/redo functionality... for a Node. Something I've not seen done before. I.e., when the Node is renamed via F2 on the Node, the "Undo/Redo" buttons should start working. Here is the start of the solution, via this item in the mailing list and Timon Veenstra's BeanNode class, note especially the items in bold: public class ShipNode extends BeanNode implements PropertyChangeListener, UndoRedo.Provider { private final InstanceContent ic; private final ShipSaveCapability saveCookie; private UndoRedo.Manager manager; private String oldDisplayName; private String newDisplayName; private Ship ship; public ShipNode(Ship bean) throws IntrospectionException { this(bean, new InstanceContent()); } private ShipNode(Ship bean, InstanceContent ic) throws IntrospectionException { super(bean, Children.LEAF, new ProxyLookup(new AbstractLookup(ic), Lookups.singleton(bean))); this.ic = ic; setDisplayName(bean.getType()); setShortDescription(String.valueOf(bean.getYear())); saveCookie = new ShipSaveCapability(bean); bean.addPropertyChangeListener(WeakListeners.propertyChange(this, bean)); } @Override public Action[] getActions(boolean context) { List<? extends Action> shipActions = Utilities.actionsForPath("Actions/Ship"); return shipActions.toArray(new Action[shipActions.size()]); } protected void fire(boolean modified) { if (modified) { ic.add(saveCookie); } else { ic.remove(saveCookie); } } @Override public UndoRedo getUndoRedo() { manager = Lookup.getDefault().lookup( UndoRedo.Manager.class); return manager; } private class ShipSaveCapability implements SaveCookie { private final Ship bean; public ShipSaveCapability(Ship bean) { this.bean = bean; } @Override public void save() throws IOException { StatusDisplayer.getDefault().setStatusText("Saving..."); fire(false); } } @Override public boolean canRename() { return true; } @Override public void setName(String newDisplayName) { Ship c = getLookup().lookup(Ship.class); oldDisplayName = c.getType(); c.setType(newDisplayName); fireNameChange(oldDisplayName, newDisplayName); fire(true); fireUndoableEvent("type", ship, oldDisplayName, newDisplayName); } public void fireUndoableEvent(String property, Ship source, Object oldValue, Object newValue) { ReUndoableEdit reUndoableEdit = new ReUndoableEdit( property, source, oldValue, newValue); UndoableEditEvent undoableEditEvent = new UndoableEditEvent( this, reUndoableEdit); manager.undoableEditHappened(undoableEditEvent); } private class ReUndoableEdit extends AbstractUndoableEdit { private Object oldValue; private Object newValue; private Ship source; private String property; public ReUndoableEdit(String property, Ship source, Object oldValue, Object newValue) { super(); this.oldValue = oldValue; this.newValue = newValue; this.source = source; this.property = property; } @Override public void undo() throws CannotUndoException { setName(oldValue.toString()); } @Override public void redo() throws CannotRedoException { setName(newValue.toString()); } } @Override public String getDisplayName() { Ship c = getLookup().lookup(Ship.class); if (null != c.getType()) { return c.getType(); } return super.getDisplayName(); } @Override public String getShortDescription() { Ship c = getLookup().lookup(Ship.class); if (null != String.valueOf(c.getYear())) { return String.valueOf(c.getYear()); } return super.getShortDescription(); } @Override public void propertyChange(PropertyChangeEvent evt) { if (evt.getPropertyName().equals("type")) { String oldDisplayName = evt.getOldValue().toString(); String newDisplayName = evt.getNewValue().toString(); fireDisplayNameChange(oldDisplayName, newDisplayName); } else if (evt.getPropertyName().equals("year")) { String oldToolTip = evt.getOldValue().toString(); String newToolTip = evt.getNewValue().toString(); fireShortDescriptionChange(oldToolTip, newToolTip); } fire(true); } } Undo works when rename is done, but Redo never does, because Undo is constantly activated, since it is reactivated whenever there is a name change. And why must the UndoRedoManager be retrieved from the Lookup (it doesn't work otherwise)? Don't get that part of the code either. Help welcome!

• OpenVPN / iptables restrict some access

  - by RitonLaJoie

  I want to create an openvpn service on a dedicated server I have, for some friends so that they are able to play online games faster. Is there an easy way to restrict which traffic I allow them with iptables ? It seems iptable is not very easy to maintain and we can easily get kicked out of our own server. Rebooting on a rescue mode every time I would get kicked out because of bad iptable rules would just be a pain. As far as I understand, the tun interface would be providing the access. Which kind of rule in iptables would I have to implement to restrict their access to only 1 ip ? Also, I don't want this vpn to be the default gateway for all the traffic. I guess I should go with the option of pushing a route to the clients so that they connect to the IP of the game server through the VPN and use their regular routes through their ISP for all the other traffic ? As a side not, it seems Openvpn AS is not very robust. Is there some other (commercial is ok) product that would give me the same administration options through a web interface ? Is Webmin the only other solution ? Thanks !

• cannot connect to my nginx server from remote machine

  - by margincall

  I thought that it's iptables problem.. but it seems not. I really have no idea about this situation. I'm getting a server hosting(CentOS). I installed Nginx + Django and nginx uses 8080 port. A domain is connected to the server. When I executed "wget [domain]:8080/[app name]/" in the server, it worked. Of course, "wget 127.0.0.1:8080/[app name]/" has no problem. (wget [server ip]:8080/[app name]/, either) However, from other computers, connecting was failed. (message says, no route) I checked my firewall setting. I excuted these commands. iptables -I INPUT -p tcp --dport 8080 -j ACCEPT iptables -I OUTPUT -p tcp --sport 8080 -j ACCEPT iptables -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT /etc/init.d/iptables restart I don't really understand all options of commands and I think there were useless commands, but I just tried all googled iptables settings. But still I cannot connect to my server. What should I check, first? I don't know this is important, but add to this post. On 80 port, an apache server is running. It works fine, I can connect to apache from other computers. There is DB connecting issue, (PHP to MySQL) but I think that it is just PHP coding bug. please excuse my low-level English. I'm not native English speaker.. but I tried to explane well as far as possible. Thank you for reading this question.

• It is okay to set MASQUERADE at 2 network interfaces in a Linux server?

  - by Patrick L

  There is a Linux server with 3 network interfaces, eth0, eth1, eth2. IP forwarding has been turn on in this server. eth0 is connected to 10.0.1.0/24. Its IP is 10.0.1.1. eth1 is connected to 172.16.1.0/24. Its IP is 172.16.1.1. Server A can ping router C at 172.16.1.2. eth2 is connected to 192.168.1.0/24. Its IP is 192.168.1.1. Server A can ping server B at 192.168.1.2. Router C is able to route to 172.16.2.0/24 and 172.16.3.0/24. [10.0.1.0/24] | 172.16.2.0/24------| | [C]------172.16.1.0/24------[A]------192.168.1.0/24------[B] 172.16.3.0/24------| We have set MASQUERADE at eth0. When server B (192.168.1.2) connect to 10.0.1.0/24, IP MASQUERADE will happen at eth0. Can we set MASQUERADE at eth1? Is it okay to set MASQUERADE at more than 1 network interfaces in Linux?

• How do I tunnel an HTTPS proxy through a virtual machine (VMWare)

  - by Kyle

  I have a personal setup at home using VMWare Workstation. I also have a set of Virtual Private Machines that run Squid, and therefore provide me HTTPS proxy tunnels. Using Proxifier, I can tunnel all traffic for given applications through these tunnels. However, I also have a few virtual machines for dev/staging/experimentation/etc. I generally just use NAT to provide Internet access to the machines, and if I need to use these proxies, I can just setup Proxifier (or a Linux equivalent) to pipe the traffic through them. No problem. But... I got to thinking: Wouldn't it be great if I could assign these proxy tunnels to a virtual machine, so that when I start up the VM, it has instant-on access through the tunnel and not my local connection? (EDIT: Of course, it would USE my local connection, but it would tunnel traffic through the proxy.) To be more clear: I want a solution that binds the proxy to a VM, so that when I start the VM, I don't have to use a proxy client to connect to the tunnel - I am already piping all traffic from that VM through that proxy. I did a bit of searching, and the closest thing I could find was this: How to route public static IP to a virtual machine on a vmware ESXi host? Which wasn't all that applicable. The proxies are protected by user/pass but do not filter by IP. Again, they are HTTPS proxies setup through Squid. Any ideas on how to make this happen? Thanks a ton.

• How does everyone set up AWS for PHP with a git workflow while worrying about distributing EC2?

  - by Parris

  Hello, I have been looking for something like heroku but for php, and after much frustration (and almost finding what I need, but not quite) we decided to just go with AWS without any other abstraction. We are using PHP 5.3 (and CakePHP 1.3), and are currently using git. Ubuntu seems like the easiest way to get both of those on there and we will most likely use that. We aren't really going worry about outgoing email. We are using smtp through gmail, but will most likely switch to some other service eventually. I had 3 questions: 1) I have been looking at Zend Server, and I am not quite sure how that is more beneficial than xampp. Perhaps it is not? 2) I suppose to make the application scale we would need multiple instances of some ec2 ami. Then just duplicate it and such. The question then becomes how do we make sure all EC2 instances are up to date? 3) I understand the concept of load balancing to some degree. I understand that in 1 region you select a bunch of servers and have it load balance across them. The question then becomes well how about world wide? How do I make it so that traffic is directed to the correct ec2 server? I have heard of route 53, and tried signing up for that, but nothing appears in my control panel. Also perhaps it is just a DNS thing with my domain registrar? AHHH... some tutorial would be helpful!

PoolDict[key].Add(obj); PoolDict[key][0].Add(obj); } I'd like to replace the line after //PlaceHolder with code that will assign a gameObject to an existing array in a list that's associated with a key. How could this be done?

• mdadm: Replacing array with entirely new drives

  - by hellfur

  I have a server with three 500GB drives, with most of my data in a RAID5 configuration spanning the three of them. I just purchased and installed four 1TB drives, and the intention is to move off of the old drives and onto the new ones. I have enough SATA ports and power connectors to power all seven of my drives at once, so I've kept the old RAID running while I figure out what to do with the new drives. My question is: Should I create a whole new array on the 1TB drives, then move everything over and reconfigure linux to boot from the new md arrays? Or should I just expand the array, swapping out each of the three 500GBs with the 1TB, then adding the final drive? I've read up on the mdadm extending drive setup, and it makes sense, but I imagine I would use one of the drives as a full backup while I move things over, then add that drive back into the array once things are up and running on three of the 1TB drives, so there's some complication in going that route as well... I'm just not sure which is safer/recommended.

• What ports, besides 80, need to be available to send (only send) email using phpmailer to gmail over SSL?

  - by Wobblefoot

  Using phpmailer I keep getting a 110 timeout and "Unable to connect to host" when sending email from my web server. The authentication details are right and they work on another server I have (login, pwd, ports etc and gmail acct set up for SSL connections on 465), but it's failing on my new server. FIREWALL: I allow related/established, port 80 and a port for SSH on INPUT, then this on OUTPUT: 7906 474K DROP tcp -- any any anywhere anywhere tcp dpt:smtp 0 0 ACCEPT tcp -- any any localhost.localdomain yw-in-f109.1e100.net tcp dpt:submission 0 0 ACCEPT tcp -- any any localhost.localdomain gx-in-f109.1e100.net tcp dpt:ssmtp 0 0 DROP tcp -- any any anywhere anywhere tcp dpt:submission 9 540 DROP tcp -- any any anywhere anywhere tcp dpt:ssmtp This output chain works on my other server and disabling it doesn't get mail delivered either. WEB SERVER: Varnish (80) Nginx (8088) Drupal 7 PHP5-FPM APC MySQL All works beautifully, except for outgoing email. What else could it be? I understand phpmailer does NOT require a local MTA or procmail (this is sort of the point - I don't want the security or admin overhead of a full blown MTA on my web server). Am I wrong? Do I need an MTA as well? What local ports and programs are used to authenticate over SSL and route mail using phpmailer? Any ideas at all greatly appreciated - wasted a day on this nonsense already!

• How to remove items from an arraylist without shrinking the list [migrated]

  - by user73710

  I have a case where I am using the ArrayList to keep a list of items that are keyed by their position in the list. Other objects reference the ArrayList items by their position. If I delete one of the items from the list, I don't want the list to shrink because that would invalidate all other references to items in the list (e.g. item 2 is now in position 1). My solution to the shrinking array list problem is to null the position in the arraylist so that the list will not shrink. I am curious whether this will free the memory formerly held by the item at that position. If there is a better way to accomplish this requirement, I would like to know about it.

• PPTP VPN on Server 2008 Enterprise

  - by Mike K

  I asked this question on Server fault and was told that was not allowed so im moving it here. I am running Windows Server 2008 enterprise in my HOME network inside of vmware workstation. I am running this on my home network to setup a PPTP VPN connection at home. I have correctly setup everything I needed to make it work, including opening all the ports, 1723 and 43 (GRE). I am able to connect just fine, but when I connect I dont have internet unless I uncheck use remote gateway. The thing is, I want to use the remote gateway to route all my traffic through that connection. Can someone tell me why this isnt working and how to get it to work. When I have remote gateway checked, and I do an ipconfig I dont get a remote gateway for the VPN connection, its 0.0.0.0 when id assume if connected properly should be 192.168.1.254 (my ATT Home Router). Also, if I cant get the remote gateway issue to work, and I have to uncheck that box to get internet, does this mean my VPN session is no longer encrypted? I am fully aware the PPTP VPN is the weakest VPN encryption out there but still having that extra layer of security when im on an unsecure wifi connection makes me feel a bit better. Thank you for all your help in advance. Someone told me I need to setup a gateway or router configured on the server. If thats the case, how go I go about telling the remote co

• [deb-5.0] Setup DNS on my server so I can put my IPs in as nameservers of my domain provider

  - by Maurycy Zarzycki

  Basically, my unmanaged VPS provider doesn't supply me with nameserver which I can use with my domain provider to route domain to my server. As I've been told: You need to configure the custom DNS server in your VPS, to setup the custom nameservers. Please refer the following article that would help: http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch18_:_Configuring_DNS Once you configure the nameserver records, please update the domain registrar panel with the custom nameserver details. I tried to follow this guide but it seems to be a bit outdated, and I am complete newb with non-windows systems. I also scanned the google for other articles which could help me with this problem but, alas, nothing I found was of any value for someone who doesn't know this stuff better than his own pockets. I realize this is quite a complex thing to do, but maybe there is some way to automate it? Or a better solution, like a paid service which would act as my nameservers (this one would be interesting), or even hoped to find some company which "rents" people to do stuff like that. Blah, any help will be appreciated, I am at a complete loss here. I can follow some of these steps, but then I soon find that half of the files which are mentioned in the article are somehow not existing anywhere on the server which confuses me, and once we get to the point of creating Zone I can't really decipher all the things written there :/. As per title, my system is Debian 5.0.

• Why can't I get 100% code coverage on a method that calls a constructor of a generic type?

  - by Martin Watts

  Today I came across a wierd issue in a Visual Studio 2008 Code Coverage Analysis. Consider the following method:  private IController GetController<T>(IContext context) where T : IController, new() {     IController controller = new T();     controller.ListeningContext = context;     controller.Plugin = this;     return controller; } This method is called in a unit test as follows (MenuController has an empty constructor): controller = plugin.GetController<MenuController>(null);  After calling this method from a Unit Test, the following code coverage report is generated: As you can see, Code Coverage is only 85%. Looking up the code results in the following: Apparently, the call to the constructor of the generic type is considered only partly covered. WHY? Google didn't help. And MSDN didn't help at all, of course. Anybody who does know?

• 3 Server, is this a cluster scenario?

  - by HornedBeast

  Hello, At the moment I have one Ubuntu server, 9.10, running with a simple Samba share, a mail server, DNS server and DHCP server. Mostly its just there for file sharing and email server. I also have 2 other servers that are exactly the same hardware and spec as the first, which have an rsync set up to retrieve the shared folders and backs them up. However, if the first server goes down, all of our shares disappear along with our mail and the system must be rebuilt. Also I tend to find if people are downloading a large amount from the file server, no-one can access there emails - especially in the morning when everyone is signing in at once. Would it be more beneficial for me to have all 3 servers, all running the same services, doing the same thing with some sort of cluster with load balancing? In short, how can I get the best out of my 3 hardware servers? I'm not really sure where to begin looking, or how to go about such a setup where 3 servers are all identical, but perhaps one acts as the main load balancer?? If someone can point me in the right direction, or if this simply sounds like one of those Enterprise Cloud's that is now a default setup in Ubuntu Server 9.10+, then I'll go down that route. Cheers in advance. Andy

• iphone: Help with AudioToolbox Leak: Stack trace/code included here...

  - by editor guy

  Part of this app is a "Scream" button that plays random screams from cast members of a TV show. I have to bang on the app quite a while to see a memory leak in Instruments, but it's there, occasionally coming up (every 45 seconds to 2 minutes.) The leak is 3.50kb when it occurs. Haven't been able to crack it for several hours. Any help appreciated. Instruments says this is the offending code line: [appSoundPlayer play]; that's linked to from line 9 of the below stack trace: 0 libSystem.B.dylib malloc 1 libSystem.B.dylib pthread_create 2 AudioToolbox CAPThread::Start() 3 AudioToolbox GenericRunLoopThread::Start() 4 AudioToolbox AudioQueueNew(bool, AudioStreamBasicDescription const*, TCACallback const&, CACallbackTarget const&, unsigned long, OpaqueAudioQueue*) 5 AudioToolbox AudioQueueNewOutput 6 AVFoundation allocAudioQueue(AVAudioPlayer, AudioPlayerImpl*) 7 AVFoundation prepareToPlayQueue(AVAudioPlayer*, AudioPlayerImpl*) 8 AVFoundation -[AVAudioPlayer prepareToPlay] 9 Scream Queens -[ScreamViewController scream:] /Users/laptop2/Desktop/ScreamQueens Versions/ScreamQueens25/Scream Queens/Classes/../ScreamViewController.m:210 10 CoreFoundation -[NSObject performSelector:withObject:withObject:] 11 UIKit -[UIApplication sendAction:to:from:forEvent:] 12 UIKit -[UIApplication sendAction:toTarget:fromSender:forEvent:] 13 UIKit -[UIControl sendAction:to:forEvent:] 14 UIKit -[UIControl(Internal) _sendActionsForEvents:withEvent:] 15 UIKit -[UIControl touchesEnded:withEvent:] 16 UIKit -[UIWindow _sendTouchesForEvent:] 17 UIKit -[UIWindow sendEvent:] 18 UIKit -[UIApplication sendEvent:] 19 UIKit _UIApplicationHandleEvent 20 GraphicsServices PurpleEventCallback 21 CoreFoundation CFRunLoopRunSpecific 22 CoreFoundation CFRunLoopRunInMode 23 GraphicsServices GSEventRunModal 24 UIKit -[UIApplication _run] 25 UIKit UIApplicationMain 26 Scream Queens main /Users/laptop2/Desktop/ScreamQueens Versions/ScreamQueens25/Scream Queens/main.m:14 27 Scream Queens start Here's .h: #import <UIKit/UIKit.h> #import <AVFoundation/AVFoundation.h> #import <MediaPlayer/MediaPlayer.h> #import <AudioToolbox/AudioToolbox.h> #import <MessageUI/MessageUI.h> #import <MessageUI/MFMailComposeViewController.h> @interface ScreamViewController : UIViewController <UIApplicationDelegate, AVAudioPlayerDelegate, MFMailComposeViewControllerDelegate> { //AudioPlayer related AVAudioPlayer *appSoundPlayer;

• asp.net mvc 3 iis 7.5 404 error

  - by dm80

  Well works fine on my dev machine. Deploys fine from visual studio 2010 using msdeploy to IIS 7.5 with a site named apps.mydomain.com/myapp. So essentially I want to browse to http://apps.mydomain.com/myapp but when I do I get 404 error. I have Windows authentication enabled only on the site everything else is disabled. I have installed hotfix http://support.microsoft.com/kb/980368. App pool .NET 4 integrated pipeline. I have tried classic pipeline also but doesn't work. Edit 2 executed %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir still doesn't work What am I doing wrong or do I need to do anything else?
