  • Setting up Windows network on Xen

    - by samyboy
    I'm trying to install a Windows XP server in a Xen environment. The OS is booting fine. Unfortunately I can't figure out how to set up the network settings. Dom0 is a Debian Lenny currently hosting around 10 Linux virtual servers. Windows tells me I have a "limited connection". It can't get any DHCP response, nor access other hosts in the network Here is the Xen's client config file: kernel = '/usr/lib/xen-3.2-1/boot/hvmloader' builder = 'hvm' memory = '1024' device_model='/usr/lib/xen-3.2-1/bin/qemu-dm' acpi=1 apic=1 pae=1 vcpus=1 name = 'winexchange' # Disks disk = [ 'phy:/dev/wnghosts/exchange-disk,ioemu:hda,w', 'file:/mnt/freespace/ISO/DVD1_Installation.iso,ioemu:hdc:cdrom,r' ] # Networking vif = [ 'mac=00:16:3E:0A:D0:1B, type=ioemu, bridge=xenbr0'] # video stdvga=0 serial='pty' ne2000=0 # Behaviour boot='c' sdl=0 # VNC vfb = [ 'type=vnc' ] vnc=1 vncdisplay=1 vncunused=1 usbdevice='tablet' Server config (/etc/xen/xend-config.sxp) (network-script network-bridge) (network-script network-dummy) (vif-script vif-bridge) (dom0-min-mem 512) (dom0-cpus 0) (vnc-listen '0.0.0.0') Since I use Debian I had to create a link like this: /etc/xen/qemu-ifup - /etc/xen/scripts/qemu-ifup What did I do wrong? Please tell me if you want some more info (logs, etc)

  • Java Desktop Application For Network users

    - by Motasem Abu Aker
    I'm developing a desktop application using Java. My application will run in a network environment where multiple users will access the same database through the application. There will be basic CRUD opreations (Insert, Update, Delete, & select), which means there will be chances of deadlock, or two users trying to update the same record at same time. I'm using the following Java Swing for Clients (MVC). MySQL Server for database (InnODB). Java Web start. Now, MySQL is centralized on the network, and all of the clients connect to it. The Application for ERP Purpose. I searched the internet to find a very good solution to ensure data integrity & to make sure that when updating one record from one client, other clients are aware of it. I read about Socket-server-client & RESTful web services. I don't want to go web application & don't want to use any extra libraries. So how can I handle this scenario: If User A updates a record: Is there a way to update User B's screen with the new value? If user A starts updating a record, how can I prevent other users from attempting to update the same record?

  • Cannot mount a CIFS network share over VPN

    - by Aron Rotteveel
    I have setup u VPN connection to our Windows 2008 server at the office and it seems to work fine. For some reason, however, I still am not able to access the network shares over a VPN connection using my standard fstab entries. When I am physically connected to the network, it works fine, but now when trying this over VPN I get the following error: mount error(110): Connection timed out Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) My /etc/fstab looks like this: //server2008/share /mnt/share cifs iocharset=utf8,credentials=/home/aron/.smbcredentials,uid=1000 0 0 As said, it works fine when physically connected, but over VPN it just wont work. Any help is appreciated. EDIT: It seems the Windows firewall is making things harder on me. When I turn it off, I get a bit further, although I still get the following error message: Unable to find suitable address. The strange thing is that I have file sharing added as an exception to the firewall. Port 137-139 and port 445 are open, which should suffice, shouldn't it? EDIT Jan 20th: Still not working. When I have the firewall turned on, it times out. When I turn it off, I get the not suitable address error. Turning the firewall off is not an option, by the way.

  • Is it possible to search an apt repository via a web browser?

    - by Bryan
    I've installed the beta version of Ubuntu 10.04 server edition (x64), but the system doesn't have an internet connection. Is there a way I can find out what packages are in the apt repository with nothing more than a web browser? The reason I'm asking, is because I will have an internet connection available when the production system goes live, but it simply isn't possible to internet connect my development system.

  • Tips and Suggestions IP Address Re-Addressing?

    - by RSXAdmin
    Hello serverfault Universe, My ever evolving and expanding local area network is currently using a class-C address. My network consists of multiple subnets depending on site/location. 192.168.1.x is site HQ 192.168.5.x is secondary site 192.168.10.x is so on and so forth. Long story short - I have inherited this network design from the previous admin who has left the company which started off with a dozen people and now has just over 300 full time/part time employees. We do not yet have client VPN access; but we do have site to site VPN setup. My question is, in preparation for outside client access to my network via Cisco ASA, I would like to re-address the HQ site because I understand a 192.168.1.x or 192.168.0.x are not very good choices for a company subnet - it may conflict with a home user's LAN when connecting to my LAN, I believe? Through your experience, does anyone out there have any suggestions and tips on how I can proceed with re-addressing my subnets. If I designed this network I would have gone with a 10.0.0.0 (mask 255.255.255.0) so I am leaning towards changing it to fit. Thank you.

  • Group Policy for IE Security Zones

    - by Doug Luxem
    We are currently using the following Group Policy to control the Internet Explorer security zones: User Configuration\Administrative Templates\Windows Components\Internet Explorer\Internet Control Panel\Security Page Then setting the Site to Zone Assignment List with the various values using the following chart: Value Setting ------------------------------ 0 My Computer 1 Local Intranet Zone 2 Trusted sites Zone 3 Internet Zone 4 Restricted Sites Zone This works well; however, users are then unable to edit (or especially add) to their zone settings. Is there a way to lock in our custom zone settings while still giving users the ability to add their own sites to the security zones? Yes, I do realize the slight security risk in opening this up.

  • Class hierarchy problem in this social network model

    - by Gerenuk
    I'm trying to design a class system for a social network data model - basically a link/object system. Now I have roughly the following structure (simplified and only relevant methods shown) class Data: "used to handle the data with mongodb" "can link, unlink data and also return other linked data" "is basically a proxy object that only stores _id and accesses mongodb on requests" "it looks like {_id: ..., _out: [id1, id2,...], _inc: [id3, id4, ...]}" def get_node(self, id) "create a new Data object from the underlying mongodb" "each data object can potentially create a reference object to new mongo data" "this is needed when the data returns the linked objects" class Node: """ this class proxies linking calls to .data it includes additional network logic operations whereas Data only contains a basic database solution """ def __init__(self, data): "the infrastructure realization is stored as composition by an included object data" "Node bascially proxies most calls to the infrastructure object data" def get_node(self, data): "creates a new object of class Object or Link depending on data" class Object(Node): "can have multiple connections to Link" class Link(Node): "has one 'in' and one 'out' connection to an Object" This system is working, however maybe wouldn't work outside Python. Note that after reading links Now I have two questions here: 1) I want to infrastructure of the data storage to be replacable. Earlier I had Data as a superclass of Node so that it provided the neccessary calls. But (without dirty Python tricks) you cannot replace the superclass dynamically. Is using composition therefore recommended? The drawback is that I have to proxy most calls (link, unlink etc). Any thoughts? 2) The class Node contains the common method .get_node which is used to built new Object or Link instances after reading out the data. Some attribute of data decided whether the object which is only stored by id should be instantiated as an Object or Link class. The problem here is that Node needs to know about Object and Link in advance, which seems dodgy. Do you see a different solution? Both Object and Link need to instantiate one of all possible types depending on what the find in their linked data. Are there any other ideas how to implement a flexible Object/Link structure where the underlying database storage is isolated?

  • I see files in filezilla, but the internet denies their existance

    - by Zach L.
    I am doing some updates to a 10-year old site, and I am baffled. Everything worked great locally, so I uploaded a bunch of stuff to the server using filezilla. Within filezilla I can see all of the files, but for some reason I get a 404 when trying to view them. It seems as though (at least for the folder Im currently checking) this is happening for items which are "farther down the list" alphabetically. I tried to re-upload a file individually but it didn't change anything. Is this an indication that I hit some sort of limit with the hosting company? And if so why can I still view the files from filezilla? Please offer guidance. I am at a loss.

  • Sending changes to a terrain heightmap over UDP

    - by Floomi
    This is a more conceptual, thinking-out-loud question than a technical one. I have a 3D heightmapped terrain as part of a multiplayer RTS that I would like to terraform over a network. The terraforming will be done by units within the gameworld; the player will paint a "target heightmap" that they'd like the current terrain to resemble and units will deform towards that on their own (a la Perimeter). Given my terrain is 257x257 vertices, the naive approach of sending heights when they change will flood the bandwidth very quickly - updating a quarter of the terrain every second will hit ~66kB/s. This is clearly way too much. My next thought was to move to a brush-based system, where you send e.g. the centre of a circle, its radius, and some function defining the influence of the brush from the centre going outwards. But even with reliable UDP the "start" and "stop" messages could still be delayed. I guess I could compare timestamps and compensate for this, although it'd likely mean that clients would deform verts too much on their local simulations and then have to smooth them back to the correct heights. I could also send absolute vert heights in the "start" and "stop" messages to guarantee correct data on the clients. Alternatively I could treat brushes in a similar way to units, and do the standard position + velocity + client-side prediction jazz on them, with the added stipulation that they deform terrain within a certain radius around them. The server could then intermittently do a pass and send (a subset of) recently updated verts to clients as and when there's bandwidth to spare. Any other suggestions, or indications that I'm on the right (or wrong!) track with any of these ideas would be greatly appreciated.

  • Set up ad hoc wireless connection between Windows Vista and Mac OS X

    - by Skarab
    I have the following problem - Windows Vista does not connect to adhoc wireless network created on my Macbook. I have tried to create secured (with 40 bit key) and unsecured network but Windows Vista still has problems to connect. Windows VISTA informs me -- after 5 minutes of attempts - that setting up the connection -- with my adhoc network -- took too much time. My question: do I need to configure some settings on Vista to connect it to my Macbook? Maybe it is a problem with DHCP? Edited: I have tried the other way: http://superuser.com/questions/202890/set-up-an-adhoc-network-in-windows-vista-to-connect-to-and-share-the-internet-con

  • HTTP Protocal

    I have worked with the HTTP protocal for about ten years now and I have found it to be incredibly usefull for transfering data espicaly for remote systems and regardless of the network enviroment. Prior to the existance of web services, developers use to use HTTP to screen scrap data off of web pages in order to interact with remote systems, and then process the data as they needed. I use to use the HTTPWebRequest and HTTPWebRespones classes in order to screen scrap data from various sites that had information I needed to use if no web service was avalible. This allowed me to call just about any webpage and grab all of the content on the page. Below is piece of a web spider that I build about 5-7 years ago. The spider uses the HTTP protocal to requst webpages and then parse the data that is returned.  At the time of writing the spider I wanted to create a searchable index of sites I frequented. // C# 2.0 Framework// Creating a request for a specfic webpageHttpWebRequest webreq = (HttpWebRequest)WebRequest.Create(_Url); // Storeing the response of the webrequestwebresp = (HttpWebResponse)webreq.GetResponse(); StreamReader loResponseStream = new StreamReader(webresp.GetResponseStream()); _Content = loResponseStream.ReadToEnd(); // Adjust the Encoding of Responsestring charset = "";EncodeString(ref _Content, ref charset);loResponseStream.Close(); //Parse Data from the Respone_Content = _Content.Replace("\n", "");_Head = GetTagByName("Head", _Content);_Title = GetTagByName("title", _Content);_Body = GetTagByName("body", _Content);

  • Software vs Network Engineer (Salary, Difficulty, Learning, Happiness)

    - by B Z
    What are your thoughts on being a Software Engineer vs a Network Engineer? I've been on the software field for almost 10 years now and although I still have a great deal of fun (and challenges), I am starting to think it could be better on the "other" side. Not to degrade network engineers (i know there are many great ones out there), it seems (in general) their job is easier, the learning curve from average to good is not as steep, job is less stressful and pay is better on average. I think as software developer I could make the switch to networking and still enjoy working with computers and feel productive. I spend an enormous amount of time learning about software, practices, new technologies, new patters, etc...I think I could spend a much smaller amount of time learning about networking and be just as "good". What are your thoughts? EDIT: This is not about making easy money. Networking and Software are closely related, I love computers and programming, but if I can work with both, make more money and have less stress in my life and can spend more time with my family, then I am willing to consider a change and hence I am looking for advice that Do or Don't support this view.

  • Use wired LAN adapter by default

    - by Frantumn
    I am trying to find out if there's a way to set up network adapters so that if 2 are connected with network and internet access it will choose one over the other. Scenario: I have seen several computers running Windows 7 or Windows 8 where you are connected to a wireless network, working perfectly. Then when you plug in an Ethernet cable, it still shows the network icon in the taskbar as wireless. I would like to have my computer set up so that if there's an Ethernet cable plugged in, it uses that, and not the wireless adapter. 1) Is this possible / How? 2) Why does it stay on wireless over wired when given the option for both?

  • network manager says "device not managed"

  • Unable to print login-required images in IE

    - by Tim Fountain
    I have some images in a section of a site that require the user to be logged in in order to view. These images are served by a PHP script, which checks the user's login state and if valid, serves the binary data with the appropriate headers. This all works fine. The issue comes when a user tries to print one of these images. In Internet Explorer, when they go to print preview they get the broken image box with a red cross in the corner instead of the actual file. This is what gets printed also. All other browsers can print the images without issue. I have some images elsewhere on the site that are also served via. PHP but these don't require a login. These print fine. The PHP-powered HTML pages on the site that require a login also print fine in IE. It's just login-required images. The user hitting print preview does not seem to result in additional HTTP request to the server for the file. However I do see an additional HTTP request a few seconds later that comes from the same IP (may or may not be related), This request includes no host header, no REQUEST_URI and no user agent. The 'please login' page sends an appropriate 403 header. I've also added a far-in-future expires header to the image response itself to ensure that browsers can serve/print the files from their own cache but this hasn't made any difference. Why can't IE print the images and what else can I do to investigate or fix the problem?

  • 14.04 LTS, 32-bit, Software Updater error "Failed to download repository information: Check your internet connection"

    - by Lucas W
    There isn't much to say about this one: when I run Software Updater, I get the above error message. That can't be good. Interestingly, when I click on "Settings..." and then close the settings dialogue that pops up, all of a sudden Software Updater successfully finds updates and installs them. I thought I should bring this to the attention of the Ubuntu community. sudo apt-get update returns the following: W: Failed to fetch http://ppa.launchpad.net/deluge-team/ppa/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead. I have screen captures, but I don't have enough reputation points to post them.

  • How to use a home network patch panel?

    - by Torben Gundtofte-Bruun
    I'm planning a home network in a house that's not built yet. One recommendation is to add network sockets in various rooms and have them all end in a central place, where it all connects using a network switch. So far so good. Another recommendation says to not connect everything directly to the switch, but to a patch panel which in turn is connected to the switch. I'm unsure why this is good. Is there any practical advantage of using a patch panel if you're not planning to re-wire things very often? How does a patch panel actually work? Let's say it has 24 ports. Does it have another 24 ports on the backside that go to the switch, or what? Wikipedia isn't helpful on this. Clarification: I am planning to run network cables through conduits inside the walls and terminated with network sockets in the wall (as opposed to having just conduits and long regular network cables that have a normal plug in each end). Going by RedGrittyBrick's answer, a patch panel is nearly unavoidable in that case.

  • Diagnosing Bootstrap 3 Glyphicon Button Icons Not Showing

    - by Paulb
    I have a glyphicons in Bootstrap 3. They work very nicely here: latest Chrome latest Firefox latest Safari latest Explorer latest Android At one facility, the glyphicons don't show. The buttons come up blank. How do I troubleshoot? They are security sensitive there. I don't have systems or network access.. and am not in a position to request that. Troubleshooting with advanced tools isn't going to happen. Here's what I have access to: Internet Explorer 9 Behind a very secure firewall Sometimes, I think the glyphs not showing is the IE 9.. but my code should be addressing that. Sometimes, I think their firewall is blocking the CDN. Can I enter a URL into a browser to test if the CDN is there? Sometimes, I think my FB share and like buttons upset this facilty's firewall, and they tie the whole thing down. Any suggestions at how I begin to research this? Or maybe you have an outright idea for IE 9 and glyphs (though my code is very-very close to the demo's which work).

  • Is there an easy way to configure an Ubuntu system to function as a proxy/file server from behind an NAT?

    - by amol.kamath
    Sorry for the long question, but the situation/desire is quite complex. Here is my setup: I have a laptop which I carry around everywhere and I have a desktop sitting at home, connected to the internet through a router using NAT. My objective is to create a connection from my laptop to my desktop that can allow me to (in order of priority): Use the desktop as a proxy server Access files on the desktop remotely Control said desktop from the laptop using VNC or similar. Now here is the scene. I have already looked up and tried several ways to achieve the above goals. Teamviewer - I used it and didn't like it. This is not an option. SSH - This seems ideal, I have figured a way to use this for both proxy and file sharing. However, I am currently unable to connect it due to the NAT. I have a separate thread trying to get that to work here. VPN - I've figured out how to use this method for proxy, but not file sharing. However this faces the same problem as the above: I can't get it to connect through the NAT. Does anyone have any other solutions for what I want? Otherwise, if there are solutions to connecting through the NAT, please tell me (in the other thread). Thanks

  • API Class with intensive network requests

    - by Marco Acierno
    I'm working an API which works as "intermediary" between a REST API and the developer. In this way, when the programmer do something like this: User user = client.getUser(nickname); it will execute a network request to download from the service the data about the user and then the programmer can use the data by doing things like user.getLocation(); user.getDisplayName(); and so on. Now there are some methods like getFollowers() which execute another network request and i could do it in two ways: Download all the data in the getUser method (and not only the most important) but in this way the request time could be very long since it should execute the request to various urls Download the data when the user calls the method, it looks like the best way and to improve it i could cache the result so the next call to getFollowers returns immediately with the data already download instead of execute again the request. What is the best way? And i should let methods like getUser and getFollowers stop the code execution until the data is ready or i should implement a callback so when the data is ready the callback gets fired? (this looks like Javascript)

  • Access points fighting for dominance?

    - by Phillip Oldham
    We have a small office with a large number of wireless devices (a mixture of desktop machines, laptops, and wifi-enabled phones) all working from a single Apple Airport Extreme which extends our wired network. I've added another Airport Extreme for resiliency, since we've been seeing a decrease in performance and (as far as I understand) access points can only handle a small number of clients. I set the new AP to extend the current network so that the clients weren't constantly switching between different wireless networks, however as soon as this AP was configured all the wireless devices started seeing network trouble, flicking on and off. I'm assuming that this is because both APs are reasonably strong, and the client can't decide which to use. What is the best route to follow to resolve this? What I'm aiming for is wireless resiliency; preferably having two APs share the network load, or if this isn't an option then having a primary AP with a "fail-over", should the primary go down for any reason.
