  • Network tries to reindentify itself now and then

    - by Don Young
    When the computer starts up it connects itself to the router (ZTE 4G router) automatically, but after I have surfed the web for a while, it tries to identify itself, meaning you get that little blue circle next to the little screen at the corner. When browsing it does not cause any problems, but if I'm streaming a video the video will then stop, I'll have to refresh the page to make the video start again. And if I'm playing a game, LoL for example, the game will freeze for about 2 seconds then continue again (due to lost connection to the internet). I have no virus on my computer, although I had before. I have reset my router, restarted my computer, updated my ethernet driver, checked so that the IPv4 is set on automatic and tried different router channels. I have had this router for a few months and the problem just started recently. Here is the ipconfig screen:

  • How to set up dual wired and wireless connections?

    - by Col
    My laptop has both wireless and a wired connection capabilities. Can I connect to a router A using wireless and a separate router B using wired ethernet at the same time without having to switch back and forth? Thanks for replying so quickly. I wish to connect to two separate networks. The wireless connection is to router A which is connected to broadband internet. The wired connection is to router B which I wish to share files and a printer on 1 or 2 other desktops also using wired connections on B and maybe using synergy to have only one keyboard and mouse for 2 desktops. The wireless laptop is the only one required to have internet access.

  • jqgrid sample using array data, what am I missing

  • GET is not working for firstResource Rest example

    - by Anandan
    Hi, I am newbie to rest. I am using the following code example to understand the RESTlet. http://www.restlet.org/documentation/1.1/firstResource I am using RESTClient addon to firefox for testing. When i do GET on http://localhost/rest, i get a response "ok". But when i do GET on http://localhost/items, I get an error "404 Not found" Here's the sample code: public synchronized Restlet createRoot() { Router router = new Router(getContext()); router.attach("/items", ItemsResource.class); router.attach("/items/{itemName}", ItemResource.class); Restlet restlet = new Restlet() { @Override public void handle(Request request, Response response) { StringBuilder stringBuilder = new StringBuilder(); stringBuilder.append("ok"); response.setEntity(new StringRepresentation(stringBuilder .toString(), MediaType.TEXT_HTML)); } }; router.attach("/rest", restlet); return router; } ItemResource is same as provided in the link. and I use tomcat to run the servlet. Why am I getting the "Not found" error? Am i missing something here? Thanks & Regards, Anandan

  • Oracle Applications Cloud Release 8 Customization: Your User Interface, Your Text

    - by ultan o'broin
    Introducing the User Interface Text Editor In Oracle Applications Cloud Release 8, there’s an addition to the customization tool set, called the User Interface Text Editor  (UITE). When signed in with an application administrator role, users launch this new editing feature from the Navigator's Tools > Customization > User Interface Text menu option. See how the editor is in there with other customization tools? User Interface Text Editor is launched from the Navigator Customization menu Applications customers need a way to make changes to the text that appears in the UI, without having to initiate an IT project. Business users can now easily change labels on fields, for example. Using a composer and activated sandbox, these users can take advantage of the Oracle Metadata Services (MDS), add a key to a text resource bundle, and then type in their preferred label and its description (as a best practice for further work, I’d recommend always completing that description). Changing a simplified UI field label using Oracle Composer In Release 8, the UITE enables business users to easily change UI text on a much wider basis. As with composers, the UITE requires an activated sandbox where users can make their changes safely, before committing them for others to see. The UITE is used for editing UI text that comes from Oracle ADF resource bundles or from the Message Dictionary (or FND_MESSAGE_% tables, if you’re old enough to remember such things). Functionally, the Message Dictionary is used for the text that appears in business rule-type error, warning or information messages, or as a text source when ADF resource bundles cannot be used. In the UITE, these Message Dictionary texts are referred to as Multi-part Validation Messages.   If the text comes from ADF resource bundles, then it’s categorized as User Interface Text in the UITE. This category refers to the text that appears in embedded help in the UI or in simple error, warning, confirmation, or information messages. The embedded help types used in the application are explained in an Oracle Fusion Applications User Experience (UX) design pattern set. The message types have a UX design pattern set too. Using UITE  The UITE enables users to search and replace text in UI strings using case sensitive options, as well as by type. Users select singular and plural options for text changes, should they apply. Searching and replacing text in the UITE The UITE also provides users with a way to preview and manage changes on an exclusion basis, before committing to the final result. There might, for example, be situations where a phrase or word needs to remain different from how it’s generally used in the application, depending on the context. Previewing replacement text changes. Changes can be excluded where required. Multi-Part Messages The Message Dictionary table architecture has been inherited from Oracle E-Business Suite days. However, there are important differences in the Oracle Applications Cloud version, notably the additional message text components, as explained in the UX Design Patterns. Message Dictionary text has a broad range of uses as indicated, and it can also be reserved for internal application use, for use by PL/SQL and C programs, and so on. Message Dictionary text may even concatenate together at run time, where required. The UITE handles the flexibility of such text architecture by enabling users to drill down on each message and see how it’s constructed in total. That way, users can ensure that any text changes being made are consistent throughout the different message parts. Multi-part (Message Dictionary) message components in the UITE Message Dictionary messages may also use supportability-related numbers, the ones that appear appended to the message text in the application’s UI. However, should you have the requirement to remove these numbers from users' view, the UITE is not the tool for the job. Instead, see my blog about using the Manage Messages UI.

  • How to use jQuery Date Range Picker plugin in asp.net

    - by alaa9jo
    I stepped by this page: http://www.filamentgroup.com/lab/date_range_picker_using_jquery_ui_16_and_jquery_ui_css_framework/ and let me tell you,this is one of the best and coolest daterangepicker in the web in my opinion,they did a great job with extending the original jQuery UI DatePicker.Of course I made enhancements to the original plugin (fixed few bugs) and added a new option (Clear) to clear the textbox. In this article I well use that updated plugin and show you how to use it in asp.net..you will definitely like it. So,What do I need? 1- jQuery library : you can use 1.3.2 or 1.4.2 which is the latest version so far,in my article I will use the latest version. 2- jQuery UI library (1.8): As I mentioned earlier,daterangepicker plugin is based on the original jQuery UI DatePicker so that library should be included into your page. 3- jQuery DateRangePicker plugin : you can go to the author page or use the modified one (it's included in the attachment),in this article I will use the modified one. 4- Visual Studio 2005 or later : very funny :D,in my article I will use VS 2008. Note: in the attachment,I included all CSS and JS files so don't worry. How to use it? First thing,you will have to include all of the CSS and JS files into your page like this: <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.custom.min.js" type="text/javascript"></script> <script src="Scripts/daterangepicker.jQuery.js" type="text/javascript"></script> <link href="CSS/redmond/jquery-ui-1.8.custom.css" rel="stylesheet" type="text/css" /> <link href="CSS/ui.daterangepicker.css" rel="stylesheet" type="text/css" /> <style type="text/css"> .ui-daterangepicker { font-size: 10px; } </style> Then add this html: <asp:TextBox ID="TextBox1" runat="server" Font-Size="10px"></asp:TextBox><asp:Button ID="SubmitButton" runat="server" Text="Submit" OnClick="SubmitButton_Click" /> <span>First Date:</span><asp:Label ID="FirstDate" runat="server"></asp:Label> <span>Second Date:</span><asp:Label ID="SecondDate" runat="server"></asp:Label> As you can see,it includes TextBox1 which we are going to attach the daterangepicker to it,2 labels to show you later on by code on how to read the date from the textbox and set it to the labels Now we have to attach the daterangepicker to the textbox by using jQuery (Note:visit the author's website for more info on daterangerpicker's options and how to use them): <script type="text/javascript"> $(function() { $("#<%= TextBox1.ClientID %>").attr("readonly", "readonly"); $("#<%= TextBox1.ClientID %>").attr("unselectable", "on"); $("#<%= TextBox1.ClientID %>").daterangepicker({ presetRanges: [], arrows: true, dateFormat: 'd M, yy', clearValue: '', datepickerOptions: { changeMonth: true, changeYear: true} }); }); </script> Finally,add this C# code: protected void SubmitButton_Click(object sender, EventArgs e) { if (TextBox1.Text.Trim().Length == 0) { return; } string selectedDate = TextBox1.Text; if (selectedDate.Contains("-")) { DateTime startDate; DateTime endDate; string[] splittedDates = selectedDate.Split("-".ToCharArray(), StringSplitOptions.RemoveEmptyEntries); if (splittedDates.Count() == 2 && DateTime.TryParse(splittedDates[0], out startDate) && DateTime.TryParse(splittedDates[1], out endDate)) { FirstDate.Text = startDate.ToShortDateString(); SecondDate.Text = endDate.ToShortDateString(); } else { //maybe the client has modified/altered the input i.e. hacking tools } } else { DateTime selectedDateObj; if (DateTime.TryParse(selectedDate, out selectedDateObj)) { FirstDate.Text = selectedDateObj.ToShortDateString(); SecondDate.Text = string.Empty; } else { //maybe the client has modified/altered the input i.e. hacking tools } } } This is the way on how to read from the textbox,That's it!. FAQ: 1-Why did you add this code?: <style type="text/css"> .ui-daterangepicker { font-size: 10px; } </style> A:For two reasons: 1)To show the Daterangepicker in a smaller size because it's original size is huge 2)To show you how to control the size of it. 2- Can I change the theme? A: yes you can,you will notice that I'm using Redmond theme which you will find it in jQuery UI website,visit their website and download a different theme,you may also have to make modifications to the css of daterangepicker,it's all yours. 3- Why did you add a font size to the textbox? A: To make the design look better,try to remove it and see by your self. 4- Can I register the script at codebehind? A: yes you can 5- I see you have added these two lines,what they do? $("#<%= TextBox1.ClientID %>").attr("readonly", "readonly"); $("#<%= TextBox1.ClientID %>").attr("unselectable", "on"); A:The first line will make the textbox not editable by the user,the second will block the blinking typing cursor from appearing if the user clicked on the textbox,you will notice that both lines are necessary to be used together,you can't just use one of them...for logical reasons of course. Finally,I hope everyone liked the article and as always,your feedbacks are always welcomed and if anyone have any suggestions or made any modifications that might be useful for anyone else then please post it at at the author's website and post a reference to your post here.

  • Cannot delete a SharePoint web application

    - by Vijay
    What I have? I have normal web application and it has 3 site collections with name, "PDirectory". Other than this I have only Central administration web application in the farm. What I want? I want to delete that web application, "PDirectory". What problem am I facing? I am not able to delete the web application. I get below error when I try to delete it but, the site collections got deleted! Error: An object in the SharePoint administrative framework, "SPWebApplication Name=XXX Parent=SPWebService", could not be deleted because other objects depend on it. Update all of these dependants to point to null or different objects and retry this operation. The dependant objects are as follows: SPFarm Name=SharePoint_Config SPFarm Name=SharePoint_Config at Microsoft.SharePoint.Administration.SPConfigurationDatabase.DeleteObject(Guid id) at Microsoft.SharePoint.Administration.SPConfigurationDatabase.DeleteObject(SPPersistedObject obj) at Microsoft.SharePoint.Administration.SPPersistedObject.Delete() at Microsoft.SharePoint.Administration.SPWebApplication.Delete() at Microsoft.SharePoint.ApplicationPages.DeleteWebApplicationPage.BtnSubmit_Click(Object sender, EventArgs e) at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) Can somebody tell me how I can delete this web application? Thanks in advance!

  • Web server with static IP from cable provider

    - by Dmitri
    I have a subscription to 5 static IP addresses. I want to run a web server from behind a router. My network config is as follows: Server's local address is 10.1.10.2, has IIS running on it, port 80 and 443 (IIS is not my fault, had to be done) the server's ip address is static, the subnet mask is 255.255.255.0, gateway is 10.1.10.1, which is the local address of the cable modem / router / gateway thingy. All looks to be in textbook order as far as the LAN goes. I can get to anything on my LAN from any computer on my LAN, whether they have static IP or get it through DHCP from the cable modem/router thingy. however, I have no internet access form any of my LAN computers. I called Comcast tech support and they say they can connect to my modem/router just fine and can actually use it to ping any computer on the internet or any computer on my LAN from the router/modem (i checked, myself, this is in fact the case). However, nothing on my LAN has internet connectivity. I tried pinging the DNS servers, nothing. I tried directly typing in web sites' IP addresses, nothing, so doesn't seem to be a DNS issue. Any Ideas? What malfunction of a router could be causing such weird behavior? nay ideas or educated guesses are very much appreciated.

  • Can't connect to LAN when connected to D-Link DIR-615

    - by Senseful
    I'm have a D-Link DIR-615 Wireless N 300 Router. I didn't use the CD it comes with to set up the network. Instead I configured it manually through the router's settings that are accessed via a web browser. The main changes I made are: Secured the router so that a password is required before clients can use the wireless internet. Broadcasting 802.11N only (not B or G). I can connect to the router just fine and I'm able to access the internet. The only problem is that I don't see any of the other computers in my LAN. When I try connecting to another Wi-Fi router that I have (which is connected to the same network), I can see all of the computer's on my LAN just fine. Therefore, I'm guessing that the reason I can't connect to the LAN is not a problem with my computer and is a problem with the router instead. I'm on a MacBook Air running Mac OS X 10.6.6. I tried contacting D-Link technical support, but they only try to help you if you have problems connecting to the internet. They aren't really concerned with problems that have to do with the accessing PC's on the same network.

  • Port forwarding + shared connection with Ubuntu

    - by Joey Adams
    Because my wireless router's ethernet ports are defective, I set up a shared wireless connection from my laptop (which has wifi) to my eMac (which does not) via a crossover ethernet cable. The laptop is behind a router as 192.168.1.131, and the eMac is behind the laptop as 10.42.43.1 . The laptop is running Ubuntu 9.10 (Karmic). I achieved the shared connection through NetworkManager Applet. I right-clicked on the network icon at the topright, went to Edit Connections, selected the Wired connection named "Auto eth0", clicked "Edit...", went to the "IPv4 Settings" tab, and selected the Method "Shared to other computers". The eMac can now access the Internet. Now I want to enable port forwarding. There's a game I want to play that needs port 6112 forwarded (both TCP and UDP) in order to host games. I set up the router to enable port forwarding for 192.168.1.131 (the laptop), but port forwarding still isn't available on the eMac. I suppose I need to pretend my laptop is a router and configure port forwarding on it, indicating that incoming connections to the laptop (192.168.1.131) should be forwarded to the eMac on the shared connection (10.42.43.1 ). Thus, packets coming into the router on port 6112 would be redirected to the laptop (by the router), then to the eMac (by the laptop). My question is, how would I do that on Ubuntu (in light of NetworkManager's presence)? Also, if I can't get this to work, does anyone mind hosting a comp stomp? :D

  • Limit bandwith on network of computers

    - by Joseph34123
    We have network in office of approximately 10 computers sometimes when someone downloads something for work (e.g. syncing email with an attachment or Dropbox), everyone slows down. I could limit each computer in office but the problem is that we have an open WiFi network, and I cannot access the computers that use it. We have one main DSL router "Netopia 3347" and another router connected to it on wire for public wifi is "Linksys WRT110". I cannot change the setup we have and don't want to. There's 2 approaches here: Set office computers download limit in each computer and then I need to find out how I can set a download limit for the wifi network such as in the router settings. It's a Linksys router and I did not see the option for this, so maybe I need new router for WiFi? Don't bother with each computer and put some "specific hardware" or another computer before router so all traffic goes trough it and I can then assign priority maximum speed for each IP address. Question is what hardware do I need?

  • iptables: allowing incoming for 192.168.1.0/24 allowed incoming for all?

    - by nortally
    The internal side of my ISP router has three devices: ISP router 128.128.43.1 Firewall router 128.128.43.2 Server 128.128.43.3 Behind the Firewall router is a NAT network using 192.168.100.n/24 This question is regarding iptables running on the Server. I wanted to allow access to port 8080 only from the NAT clients behind the Firewall router, so I used this rule -A Firewall-1-INPUT -s 192.168.100.0/24 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT This worked, but UNEXPECTEDLY ALLOWED GLOBAL ACCESS, which resulted in our JBOSS server getting compromised. I now know that the correct rule is to use the Firewall router's address instead of the internal network, but can anyone explain why the first rule allowed global access? I would have expected it to just fail. Full config, mostly lifted from a RedHat server: *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :Firewall-1-INPUT - [0:0] -A INPUT -j Firewall-1-INPUT -A FORWARD -j Firewall-1-INPUT -A Firewall-1-INPUT -i lo -j ACCEPT -A Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT -A Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A Firewall-1-INPUT -m comment --comment "allow ssh from all" -A Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A Firewall-1-INPUT -m comment --comment "allow https from all" -A Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT -A Firewall-1-INPUT -m comment --comment "allow JBOSS from Firewall" ### THIS RESULTED IN GLOBAL ACCESS TO PORT 8080 ### -A Firewall-1-INPUT -s 192.168.100.0/24 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT ### THIS WORKED -A Firewall-1-INPUT -s 128.128.43.2 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPt ### -A Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited COMMIT

  • Multiple Set Peer for VPN Failover

    - by Kyle Brandt
    I will have two Cisco routers at Location A serving the same internal networks, and one router in location B. Currently, I have one router in each location with a IPSec site-to-site tunnel connecting them. It looks something like: Location A: crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location B set peer 12.12.12.12 set transform-set ESP-3DES-SHA match address internal-ips Location B: crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location A set peer 11.11.11.11 set transform-set ESP-3DES-SHA match address internal-ips Can I achieve fail over by simply adding another set peer at location B?: Location A (New secondary Router, configuration on previous router stays the same): crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location B set peer 12.12.12.12 set transform-set ESP-3DES-SHA match address internal-ips Location B (Configuration Changed): crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location A set peer 11.11.11.11 ! 11.11.11.100 is the ip of the new second router at location A set peer 11.11.11.100 set transform-set ESP-3DES-SHA match address internal-ips Cisco Says: For crypto map entries created with the crypto map map-name seq-num ipsec-isakmp command, you can specify multiple peers by repeating this command. The peer that packets are actually sent to is determined by the last peer that the router heard from (received either traffic or a negotiation request from) for a given data flow. If the attempt fails with the first peer, Internet Key Exchange (IKE) tries the next peer on the crypto map list. But I don't fully understand that in the context of a failover scenerio (One of the routers as Location A blowing up).

    I have a wired router to which my ubuntu laptop connects via ethernet. The wierless NIC of the laptop acts as a wireless hotspot on master mode. I use hostapd fo this. I have bridged eth0 and wlan0, so my wireless clients that connect to my laptop over wifi get ip from the wired router via dhcp, so the devices get registered at the wired router ( and the laptop is just an access point). I use the following commands to get my laptop+accesspoint working: sudo brctl addbr br0 sudo brctl addif br0 eth0 sudo hostapd /etc/hostapd/hostapd.conf & sudo dhclient -d br0 & sudo ifconfig wlan0 192.168.1.15 netmask 255.255.255.0 up sudo brctl addif br0 wlan0 These commands enable me to access internet on my wireless clients and also on the laptop which is acting as wireless accesspoint. But if I reboot the wired router (without rebooting the laptop that is acting as accesspoint), Internet access on the laptop+accesspoint gets lost, but on wireless clients it works fine. Even I have not been able to figure out a command which will reset the laptop interfaces to default settings, so everytime the router reboots, I have to reboot the laptop too to get into default settings so that I can re-enter the above mentioned commands. My first question is How can I have my bridge+accesspoint up and running even-though the router reboots? And is there a command to set the interfaces to a default state? (ifdown -a doesn't work, after issuing the command the bridge still remained).

  • Bridging my laptop's wireless and wired adaptors

    - by stacey.richards
    I would like to be able to connect a desktop computer that does not have a wireless adapter to my wireless network. I could just run a network cable from my ADSL/wireless router to the desktop computer but sometimes this is not practical. What I would really like to do is bridge my laptop's wireless and wired adapters in such a way that I can run a network cable from my laptop to a switch and another network cable from the switch to a desktop computer so that the desktop computer can access the Internet through my ADSL/wireless router via my latop: +--------------------+ |ADSL/wireless router| +--------------------+ | +-------------------------+ |laptop's wireless adaptor| | | |laptop's wired adaptor | +-------------------------+ | +------+ |switch| +------+ | +-----------------------+ |desktop's wired adapter| +-----------------------+ A bit of Googling suggests that I can do this by bridging my laptop's wireless and wired adapters. In Windows XP's Network Connections I select both the Local Area Connection and the Wireless Network Connection, right click and select Bridge Connections. From what I gather, this (layer 2?) bridge will examine the MAC address of traffic coming from the wireless network and pass it through to the wired network if it suspects that a network adapter with that MAC address may be on the wired side, and vice-versa. If this is the case, I would assume that when the desktop computer attempts to get an IP address from a DHCP server (which is running on the ADSL/wireless router), it would send a DHCP broadcast packet which would pass through the laptop's bridge to the router and the reply would return through the laptop's bridge back to the desktop. This doesn't happen. With some more Googling I find some instruction how this can be done with Linux. I reboot to Ubuntu 9.10 and type the following: sudo apt-get install bridge-utils sudo brctl addbr br0 sudo brctl addif br0 wlan0 sudo brctl addif br0 eth0 sudo ipconfig wlan0 0.0.0.0 sudo ipconfig eth0 0.0.0.0 Once again, the desktop cannot reach the ADSL/wireless router. I suspect that I'm missing some simple important step. Can anyone shed some light on this for me?

  • IP queue buffer

    - by summerbulb
    I seem to have an issue with IP queue. I have a linux machine that I am using to run some experiments. The linux machine is configured to be a router, having two NICs, connecting two other computers, and managing their network traffic. All incoming packages are captured, using iptables, and analyzed by a C application. The application analyzing the packets has a built-in delay, as part of the experiment. So I have one very fast computer sending packets through my linux-router and a (relatively) slow linux-router that analyses and deals with the packets, one by one. This situation leads to the fact that when I fire up a sender application on one of the computers connected to the linux-router, my IP queue on the linux-router gets filled up (almost) instantaneously. The IP queue's max length is currently set to 1024, and if it overflows, the packets are dropped. This is expected and i'm OK with it. But, (and this is where it gets interesting), every now and then I get the following error: "Failed to receive netlink message: No buffer space available" At start, I thought this was due to the IP queue overflow, but after some analysis i found that sometimes I get the error even if the IP queue buffer did not overflow, and sometime I DON'T get the message even though the buffer DID overflow. When I run > cat /proc/net/ip_queue, I get the following table (also used to monitor the IP queue overflow): Peer PID : 27389 Copy mode : 2 Copy range : 65535 Queue length : 0 Queue max. length : 1024 Queue dropped : 1166875 Netlink dropped : 2916 Looking at the last two values, Queue dropped seems to refer to packets that did not manage to get into the IP queue because the buffer was full. I can see this value rise as I bombard the linux-router. Netlink dropped ( as it's name implies :) ) seems to have to do with the error i'm getting. I did my best to search for material on this error, but wasn't able to find anything that seemed to point me in the required direction. Bottom line: Why am I getting this error and what can I do to avoid it?

  • VLAN Through Switch Doesn't Work

    - by vcsjones
    I have the following scenario: I have a Cisco Aironet 1040 access point. I have it configured with two SSIDs, each going to a different VLAN. So: SSID internal : VLAN 90 SSID guest : VLAN 70 On the router side, I have a Cisco RV220W (with the radios now turned off) and have setup VLANs with like VLAN IDs. VLAN 90 : 192.168.90.0/24 VLAN 70 : 192.168.70.0/24 As far as DHCP is concerned, each VLAN has a "DHCP Server" in the router's configuration: So with the access point connected directly to the router, everything works great. I connect to the internal network, and I get a 192.168.90.x address, and the guest network gets a 70.xxx address. Next I introduced a Cisco SG200-50 PoE switch between the router and the access point. The port is configured as a trunk port, so the VLAN tags should go right through the switch back to the router. However, when something is connected to the access point, nothing works. It isn't able to get an IP address, and manually assigning one doesn't seem to let any traffic route. Given that the access point works correctly when connected to the router directly, I believe the switch is misconfigured. What am I missing here? What can I use to better diagnose what the problem might be? It's small business equipment, so CLI access is not available. Below are screenshots of the switch's config. The access point is connected to GE2.

  • linux routing issue

    - by Duc To
    Hi! I have 2 linksys routers which has linux running on it and using tomato firmware.. both has internet lines plugged on but only 1 acts as DHCP server (router 1) What I am having to achieve is that all packets goes to router 1 from internal IPs want to access internet will go out to that internet line but from 1 specific port, if router 1 detects packets from a specific source port (for ex: http port: 80), it will redirect that packet to router 2 and goes out to the internet from there.. I have found some documents which give solution that I will need a linux servers with 2 ethernet cards and then we plug both internet lines on that server and routing base on it but I do not want to do that because my boss does not want to have an extra work mantaining that server, besides, he says that the router itself already a linux one so why.. I tend to agree his points.. Can it be done or a seperate linux server acting as a router is a must? Thank you all in advance and really look forward in your replies.. I am newbie to linux network and it seems to be something out of my capacity to solve :( Your sincerely! Duc To

    What I have? I have normal web application and it has 3 site collections with name, "PDirectory". Other than this I have only Central administration web application in the farm. What I want? I want to delete that web application, "PDirectory". What problem am I facing? I am not able to delete the web application. I get below error when I try to delete it but, the site collections got deleted! Error: An object in the SharePoint administrative framework, "SPWebApplication Name=XXX Parent=SPWebService", could not be deleted because other objects depend on it. Update all of these dependants to point to null or different objects and retry this operation. The dependant objects are as follows: SPFarm Name=SharePoint_Config SPFarm Name=SharePoint_Config at Microsoft.SharePoint.Administration.SPConfigurationDatabase.DeleteObject(Guid id) at Microsoft.SharePoint.Administration.SPConfigurationDatabase.DeleteObject(SPPersistedObject obj) at Microsoft.SharePoint.Administration.SPPersistedObject.Delete() at Microsoft.SharePoint.Administration.SPWebApplication.Delete() at Microsoft.SharePoint.ApplicationPages.DeleteWebApplicationPage.BtnSubmit_Click(Object sender, EventArgs e) at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) Can somebody tell me how I can delete this web application?

  • Basic connectivity issues between Win 7 and XP mixed wired/wireless network.

    - by Pulse
    Setup: Windows 7 x64 Ultimate desktop hard wired to Asus WL500gp router (WL500gpv2-1.9.2.7-d-r1445 firmware) Several Bridged VirtualBox VM's running XP, 7, ubuntu server 10.04, Mint 9 and SuSE 11.2 Win XP Pro SP3 notebook with D-Link Airplus wireless network card. No firewall or other security software currently running on either platform (at least for the duration of the test) Situation: Router is acting DHCP server Clients are receiving correct addresses and additional parameters Internet connectivity is available from all clients Windows 7 sharing is set to Network type = work (not home group) NetBT is disabled on all clients using smb over TCP What I can do: I can ping the router and internet addresses from the wireless XP notebook I can ping the Win 7 desktop and any VM from the XP wireless notebook I can ping all devices from the router All VM's and 7 can ping each other and the router as well as Internet addresses What I can't do: I cannot ping the XP wireless notebook from either The Win 7 desktop or the VM's it alwats returns a destination host unreachable. Tracert resolves the name or the XP notebook but also returns a destination host unreachable. From the above it would seem that something is blocking connectivity in a single direction (from the Win 7 box to the Win XP notebook) only but the router can ping the XP notebook. Some fresh input would be most welcome, as this is beginning to drive me batty. Thanks
