  • Windows 8 ignores more specific route

    - by Lander
    OS: Windows 8 I have a cabled NIC (connected to router with ip 192.168.1.0) and a WIFI NIC (connected to a router with ip 192.168.1.1) . I want all traffic to go through the cabled NIC, except the 192.168.1.0/8 range should use the wifi-nic. This was working fine in Windows 7, without any manual configuration. In Windows 8 however, it's not.

  • pptpd configuration

    - by Ian R.
    I would like a little help on configuring pptp so I can use my server as a vpn server since I have 10 ip's on it and I travel a lot so that would really help me and my partners. I managed to install everything needed but my vpn client fails to connect due to some reason that I cannot understand. I know there are 2 files in pptp that you're supposed to edit so I will post my 2 files here: /etc/ppp/pptpd-options name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 proxyarp nodefaultroute lock nobsdcomp /etc/pptpd.conf option /etc/ppp/pptpd-options logwtmp localip xx.158.177.231 remoteip xx.158.177.103,xx.158.177.116,xx.158.177.121,xx.158.177.124,xx.158.177.125,xx.158.177.131,xx.158.177.134,xx.158.177.139,xx.158.177.142,xx.158.177.145 interfaces file eth0 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.231 Bcast:xx.158.177.255 Mask:255.255.254.0 inet6 addr: xx80::216:3eff:fe51:31ba/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:56352 errors:0 dropped:0 overruns:0 frame:0 TX packets:3xx15 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4884030 (4.8 MB) TX bytes:6780974 (6.7 MB) Interrupt:16 eth0:1 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.103 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:2 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.116 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:3 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.121 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:4 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.124 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:5 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.125 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:6 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.131 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:7 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.134 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:8 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.139 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:9 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.142 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:10 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.145 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:286 (286.0 B) TX bytes:286 (286.0 B)

  • How do I enable spell checking within an NSTextField on Mac OS X?

    - by Luke
    I have an NSTextField that I would like to enable "as-you-type" spell checking. When I load my application I can do this from the Menu Bar Edit Spelling and Grammar Check Spelling While Typing. I would like this option to be enabled by default. Within IB I can enable this for a NSTextView but I would like to use NSTextField for this part of the UI. Thank you.

  • Is a clear and replace more efficient than a loop checking all records?

    - by Matt
    I have a C# List, that is filled from a database.. So far its only 1400 records, but I expect it to grow a LOT.. Routinely I do a check for new data on the entire list.. What I'm trying to figure out is this, is it faster to simply clear the List and reload all the data from the table, or would checking each record be faster.. Intuition tells me that the dump and load method would be faster, but I thought I should check first...

  • Why cast null before checking if object is equal to null?

    - by jacerhea
    I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

  • How can I test email generating without creating and checking 1,000 addresses?

    - by twpc
    I am working on generating emails using Java. I would love to use some sort of system where I can send out mass emails and ensure that the emails were received by the intended recipient (A. My code to send the emails worked and B.The emails were not marked as spam). How can I do this without setting up (and keeping track of) a couple hundred email addresses and then checking each one individually? Thanks!

  • Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in file

    - by Jian Lin
    Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in files (pushing it)? It can be important that: 1) You never know it is in an inconsistent state, so you try for 2 hours trying to debug the code for what's wrong. 2) With all the framework code -- potentially hundreds of files -- if some files are inconsistent with the other, can't the rake db:migrate or script/generate controller cause some damage or inconsistencies to the code base?

  • IP address reuse on macvlan devices

    - by Alex Bubnoff
    I'm trying to create easy to use and possibly simple testing environment for some product and got some strange behaviour of macvlan's. What I'm trying to achieve: make a toolset for one-line start/stop of lxc containers(via docker) bound to external ip(I have enough of it on host machine). So, I'm doing something like this: docker run -d -name=container_name container_image pipework eth1 container_name ip/prefix_len@gateway and pipework here does this: GUEST_IFNAME=ph$NSPID$eth1 ip link add link eth1 dev $GUEST_IFNAME type macvlan mode bridge ip link set eth1 up ip link set $GUEST_IFNAME netns $NSPID ip netns exec $NSPID ip link set $GUEST_IFNAME name eth1 ip netns exec $NSPID ip addr add $IPADDR dev eth1 ip netns exec $NSPID ip route delete default ip netns exec $NSPID ip link set eth1 up ip netns exec $NSPID ip route replace default via $GATEWAY ip netns exec $NSPID arping -c 1 -A -I eth1 $IPADDR And it works for first time per IP. But for second time and later packets for containers IP isn't getting into container, while all configuration seem fine. So it looks like this: External machine ? ping 212.76.131.212 ....silence....

Can this be caused by not a bug in macvlan implementation? Is there any tools I can use to debug that configuration?

  • KVM/Libvirt bridged/routed networking not working on newer guest kernels

    - by SharkWipf
    I have a dedicated server running Debian 6, with Libvirt (0.9.11.3) and Qemu-KVM (qemu-kvm-1.0+dfsg-11, Debian). I am having a problem getting bridged/routed networking to work in KVM guests with newer kernels (2.6.38). NATted networking works fine though. Older kernels work perfectly fine as well. The host kernel is at version 3.2.0-2-amd64, the problem was also there on an older host kernel. The contents of the host's /etc/network/interfaces (ip removed): # Loopback device: auto lo iface lo inet loopback # bridge auto br0 iface br0 inet static address 176.9.xx.xx broadcast 176.9.xx.xx netmask 255.255.255.224 gateway 176.9.xx.xx pointopoint 176.9.xx.xx bridge_ports eth0 bridge_stp off bridge_maxwait 0 bridge_fd 0 up route add -host 176.9.xx.xx dev br0 # VM IP post-up mii-tool -F 100baseTx-FD br0 # default route to access subnet up route add -net 176.9.xx.xx netmask 255.255.255.224 gw 176.9.xx.xx br0 The output of ifconfig -a on the host: br0 Link encap:Ethernet HWaddr 54:04:a6:8a:66:13 inet addr:176.9.xx.xx Bcast:176.9.xx.xx Mask:255.255.255.224 inet6 addr: fe80::5604:a6ff:fe8a:6613/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:20216729 errors:0 dropped:0 overruns:0 frame:0 TX packets:19962220 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:14144528601 (13.1 GiB) TX bytes:7990702656 (7.4 GiB) eth0 Link encap:Ethernet HWaddr 54:04:a6:8a:66:13 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:26991788 errors:0 dropped:12066 overruns:0 frame:0 TX packets:19737261 errors:270082 dropped:0 overruns:0 carrier:270082 collisions:1686317 txqueuelen:1000 RX bytes:15459970915 (14.3 GiB) TX bytes:6661808415 (6.2 GiB) Interrupt:17 Memory:fe500000-fe520000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:6240133 errors:0 dropped:0 overruns:0 frame:0 TX packets:6240133 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6081956230 (5.6 GiB) TX bytes:6081956230 (5.6 GiB) virbr0 Link encap:Ethernet HWaddr 52:54:00:79:e4:5a inet addr:192.168.100.1 Bcast:192.168.100.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:225016 errors:0 dropped:0 overruns:0 frame:0 TX packets:412958 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:16284276 (15.5 MiB) TX bytes:687827984 (655.9 MiB) virbr0-nic Link encap:Ethernet HWaddr 52:54:00:79:e4:5a BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) vnet0 Link encap:Ethernet HWaddr fe:54:00:93:4e:68 inet6 addr: fe80::fc54:ff:fe93:4e68/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:607670 errors:0 dropped:0 overruns:0 frame:0 TX packets:5932089 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:83574773 (79.7 MiB) TX bytes:1092482370 (1.0 GiB) vnet1 Link encap:Ethernet HWaddr fe:54:00:ed:6a:43 inet6 addr: fe80::fc54:ff:feed:6a43/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:922132 errors:0 dropped:0 overruns:0 frame:0 TX packets:6342375 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:251091242 (239.4 MiB) TX bytes:1629079567 (1.5 GiB) vnet2 Link encap:Ethernet HWaddr fe:54:00:0d:cb:3d inet6 addr: fe80::fc54:ff:fe0d:cb3d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:9461 errors:0 dropped:0 overruns:0 frame:0 TX packets:665189 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:4990275 (4.7 MiB) TX bytes:49229647 (46.9 MiB) vnet3 Link encap:Ethernet HWaddr fe:54:cd:83:eb:aa inet6 addr: fe80::fc54:cdff:fe83:ebaa/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1649 errors:0 dropped:0 overruns:0 frame:0 TX packets:12177 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:77233 (75.4 KiB) TX bytes:2127934 (2.0 MiB) The guest's /etc/network/interfaces, in this case running Ubuntu 12.04 (ip removed): # This file describes the network interfaces available on your system # and how to activate them.

  • Why the parent page get refreshed when I click the link to open thickbox-styled form?

    - by user333205
    Hi, all: I'm using Thickbox 3.1 to show signup form. The form content comes from jquery ajax post. The jquery lib is of version 1.4.2. I placed a "signup" link into a div area, which is a part of my other large pages, and the whole content of that div area is ajax+posted from my server. To make thickbox can work in my above arangement, I have modified the thickbox code a little like that: //add thickbox to href & area elements that have a class of .thickbox function tb_init(domChunk){ $(domChunk).live('click', function(){ var t = this.title || this.name || null; var a = this.href || this.alt; var g = this.rel || false; tb_show(t,a,g); this.blur(); return false; });} This modification is the only change against the original version. Beacause the "signup" link is placed in ajaxed content, so I Use live instead of binding the click event directly. When I tested on my pc, the thickbox works well. I can see the signup form quickly, without feeling the content of the parent page(here, is the other large pages) get refreshed. But after transmiting my site files into VHost, when I click the "signup" link, the signup form get presented very slowly. The large pages get refreshed evidently, because the borwser(ie6) are reloading images from server incessantly. These images are set as background images in CSS files. I think that's because the slow connection of network. But why the parent pages get refreshed? and why the browser reloads those images one more time? Havn't those images been placed in local computer's disk? Is there one way to stop that reloadding? Because the signup form can't get displayed sometimes due to slow connection of network. To verified the question, you can access http://www.juliantec.info/track-the-source.html and click the second link in left grey area, that is the "signup" link mentioned above. Thinks!

  • Object reference not set to an instance of an object- Linked List Example

    - by Zoro Roronoa
    I am seeing following errors : Object reference not set to an instance of an object! Check to determinate if the object is null before calling the method! I'am new with C#,and I made a program for Sorted Linked Lists. Here is the code where the error comes! public void Insert(double data) { Link newLink = new Link(data); Link current = first; Link previous = null; if (first == null) { first = newLink; } else { while (data > current.DData && current != null) { previous = current; current = current.Next; } previous.Next = newLink; newLink.Next = current; } } It says that the current referenc is null while (data current.DData && current != null), but I assigned it current = first; Please Help ! The rest is the complete code of the Program! class Link { double dData; Link next=null; public Link Next { get { return next; } set { next = value; } } public double DData { get { return dData; } set { dData = value; } } public Link(double dData) { this.dData = dData; } public void DisplayLink() { Console.WriteLine("Link : "+ dData); } } class SortedList { Link first; public SortedList() { first = null; } public bool IsEmpty() { return (this.first == null); } public void Insert(double data) { Link newLink = new Link(data); Link current = first; Link previous = null; if (first == null) { first = newLink; } else { while (data > current.DData && current != null) { previous = current; current = current.Next; } previous.Next = newLink; newLink.Next = current; } } public Link Remove() { Link temp = first; first = first.Next; return temp; } public void DisplayList() { Link current; current = first; Console.WriteLine("Display the List!"); while (current != null) { current.DisplayLink(); current = current.Next; } } } class SortedListApp { public void TestSortedList() { SortedList newList = new SortedList(); newList.Insert(20); newList.Insert(22); newList.Insert(100); newList.Insert(1000); newList.Insert(15); newList.Insert(11); newList.DisplayList(); newList.Remove(); newList.DisplayList(); } }

  • Can any web-based email program let user paste an image (not link) as part of the email instead of a

    - by Jian Lin
    I think back in the old days, some email programs let users Paste an image right inside the email content. (maybe WinMail or Outlook?) So for example, we can write some text, embed an image, and then write some more text, and embed another image. The recipient will get the email content in the above text-image-text-image order (instead of having all images attached at the end of email) Can any web-based email program do that? Note that the image is not just a link, but a complete file. For example, Gmail lets us paste an image, but it is actually just a link to some web location. Can the actual file content be embedded instead?

  • WordPress > Optimizing a query to show recent posts with a "View All" link when postcount exceeds ma

    - by Scott B
    I have a setting in my theme that allows the site owner to set the maximum number of posts ($maxPosts) to display in a "Recent Posts" menu. I'm using a custom script to generate the recent posts (because the Recent Posts widget does not highlight the current page, which I need for my css). My menu also is set up to display a "View All" link below the post listing, but only if the actual post count is $maxposts I'm trying to work out the best method for getting the post count and comparing it to $maxposts in order to determine whether or not to show a "View All" link. I'm sure there's probably a better way, but here's my code. I'm looking to optimize it to support very large post counts... $cat=get_cat_ID('excludeFromRecentPosts'); $catHidden=get_cat_ID('hidden'); $myquery = new WP_Query(); $myquery->query(array( 'cat' => "-$cat,-$catHidden", 'post_not_in' => get_option('sticky_posts') )); $myrecentpostscount = $myquery->found_posts; if ($myrecentpostscount > 0) { //show the menu if ($myrecentpostscount > $maxPosts) { //show "View All" link } } I really only need to determine if the total post count from the query is greater than the maxPost setting in order to determine whether to show the "View All" link, so I'm wondering if, in the case there are thousands of posts matching the criteria, to avoid performance issues, I don't need to get a count of all of them. I just need to count up until the point of maxPosts + 1, and that's where I'm struggling a bit because the user could elect to make maxPosts = -1 which means they want to show all posts. But this would be impractical, so I would probably set a upper limit of 20...

  • How can I make an AJAX link work once it is moved out of the iFrame?

    - by KcYxA
    Hi, I am using an iFrame with a form that return some content with an AJAX link. I am then moving the returned content out of the iFrame into the main page. However, then the ajax link does not work and the error "Element is null" is created once the link is clicked. How can I move content from the iFrame and still have the AJAX link working? Here's the code returned by the iFrame: <span id="top"> <a id="link8" onclick=" event.returnValue = false; return false;" href="/item_pictures/delete/7"> <img src="/img/delete.bmp"/> </a> <script type="text/javascript"> parent.Event.observe('link8', 'click', function(event) { new Ajax.Updater('top','/item_pictures/delete/3', { asynchronous:true, evalScripts:true, onCreate:function(request, xhr) { document.getElementById("top").innerHTML = "<img src=\"/img/spinner_small.gif\">"; }, requestHeaders:['X-Update', 'top'] }) }, false); </script> </span>

  • Is real-time or synchronous replication possible over WAN link?

    - by johnnyb10
    The company I work for is looking to implement truly real-time file replication with file locking over a WAN link that spans over 2000 miles. We currently have a 16-drive SAN setup in our east coast office. We also have an office out in Colorado that will have the same exact SAN setup. The idea is to have those two SANs contain the same exact data at all times, which will allow us to work with the same data pool, and which will also provide use with an offsite backup solution, should a failure occur on either end. We're running Server 2008. The objective is to enable users in the east coast office to work on files and have those changes be instantly updated on the Colorado SAN as well. We also need there to be file locking so that there will be no conflicts or overwritten changes if users attempt to work on the same file. Is this scenario even possible, at speeds that would make the files usable? And if so, what software would we need to pull this off? As I understand it, DFS-R does not provide file locking, so if we used that, we would need to go with a third-party product like Peerlock. But I don't even know if DFS-R is an option. Can it replicate quickly enough over a WAN link? Can any product? It seems that if we were to use synchronous replication, the programs would be unacceptably slow, as every write would have to wait for confirmation from the other end of the link. But if we used asynchronous replication, what kind of latency would we be looking at? There is a product from GlobalScape called WAFS that claims to provide "File coherence with real-time file locking, file release, and synchronization" and says that "As files are modified, changes are mirrored instantly using intelligent byte-level differencing to minimize the impact on network bandwidth". So this sounds like synchronous replication, but that doesn't even seem possible, given physical limitations such as the speed of light. If anyone has any experience with this kind of setup, or knows whether it's even possible, I'd appreciate your input and suggestions, including recommendations for software that we should check out.

  • Invert linear linked list

    - by ArtWorkAD
    Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

  • Most efficient way to store list structure in XML

    - by Mike
    Starting a new project and was planning on storing all of my web content in XML. I do not have access to a database so this seemed like the next best thing. One thing I'm struggling with is how to structure the XML for links (which will later be transformed using XSLT). It needs to be fairly flexible as well. Below is what I started with, but I'm starting to question it. <links> <link> <url>http://google.com</url> <description>Google</description> <link> <link> <url>http://yahoo.com</url> <description>Yahoo</description> <links> <url>http://yahoo.com/search</url> <description>Search</description> </link> <link> </links> That should get transformed into Google Yahoo Search Perhaps something like this might work better. <links> <link href="http://google.com">Google</link> <link href="http://yahoo.com">Yahoo <link href="http://yahoo.com/search">Search</link> </link> </links> Does anyone perhaps have a link that talks about structuring web content properly in XML? Thank you. :)

  • When clicking an irc:// link, a new instance of chatzilla opens instead of the existing one being used.

    - by WebDevHobo
    That is my problem in a nutshell. I'm running Win7 32-bit. I have chatzilla on XulRunner, so not as the Firefox add-on. When I clock any irc:// link, a new instance of Chatzilla will be started. I have a lot of startup-commands set, so all those will be executed. I stop the new instance before it takes off, but this is rather annoying. Firefox application setting just link to the path where the executable is, with no option to set any command-line stuff to make the existing instance be used. Is there any firefox or windows setting that I can manipulate, so that when firefox calls chatzilla.exe, the existing instance is used instead of a new one opened?

  • Can you link an NTFS junction point to a directory on a Network Attached Storage?

    - by Zachary Burt
    I'm using Windows, and I want to use Dropbox to back up a folder outside my Dropbox directory. So I want to create a junction point from my target directory to my Dropbox folder. Accoding to the Wikipedia article on NTFS junction points, which the Dropbox answer links to: "Junction points can only link to directories on a local volume; junction points to remote shares are unsupported." I am looking to link to a directory on networked attached storage, which would not be a local volume, I believe. What should I do?
