  • Wireless Network Issue, Disconnecting Randomly From Network

    - by Surfer513
    I'm having an odd problem with my wireless network. Here is the background information: Server (Windows Server 2008) 1 to 10 end user machines connecting to the network Layer 3 Access Point (Asus WL-330 gE) connected to ethernet of Server and all machines connect to the network via the AP The end user machines get a connection to the server with no problems initially. But then connections are randomly lost throughout the day to the server/network. The wireless NICs of the machines still see the wireless network but are unable to connect to it. Then after some time the connection is regained automatically. I initially thought there was a problem with this particular AP, but then I took the same make/model AP out of storage and still ran into the problem. Any ideas what could be causing this??? Very confusing that the wireless nics on the end user machines can still see the network but not connect, and that the connections are randomly lost/gained. Thanks in advance!

  • What's wrong with my custom patch cables?

    - by stu42j
    I have a box of bulk Cat5e riser cable left over from when I had my house wired. I figured I could use this to make some custom length cables for connecting my computers, switches, etc. I had a crimper already so I bought a bag of RJ45 plugs. I made a few cables several years ago, but my experience/knowledge with this sort of thing is minimal. None of my cables are working. I don't have a tester so I just plug the cable into a computer and switch but I get no link light. I wired them them all straight-through and visual inspection doesn't show any problems. Any ideas what I might be doing wrong?

  • How do I configure an interface to have *both* a DHCP address and a static address in Ubuntu?

    - by Paul Hoffman
    In a lab setup, I want eth0 on a Ubuntu server box to get a DHCP address for talking to the outside world, and I also want to assign it a static 10.x.y.z address for talking to other boxes on the local network that have 10.x.y.z addresses. I want to do this by editing /etc/network/interfaces. The man page for /etc/network/interfaces is modeled after "here's a bunch of examples, I hope you can figure out the actual rules on your own". I don't see a way to give one interface two addresses using two different methods (static and dhcp), and initial fumbling didn't produce useful results.

  • Setup IPsec VPN using ASA5505 behind Juniper SSG5

    - by i_ch3ry
    I have been assigned to establish a Internet IPsecVPN connection between two sites using Cisco ASA5505 A site currently has following setup.(Same setup is expected in another site) Internet-----ADSL Router-----Juniper SSG5-----Intranet (Im not sure what is configured on SSG5 and if router is in bridge mode or if NAT is configured) I was thinking if I should install ASA5505 along with Juniper SSG5? Internet-----ADSL Router-----Juniper SSG5-----Cisco ASA5505(for vpn only)------Intranet or Internet-----ADSL Router-----Cisco ASA5505(for vpn only)-----Juniper SSG5------Intranet My question is if it is possible? What should be the normal way to achieve this goal? Thanks

  • How do I connect two computers with a LAN cable?

    - by John
    I have two machines - Windows XP and a laptop using Windows 7. I connected them with a WLAN cable. On the Windows XP machine, I set the IP address to 192.168.0.10. On the Windows 7 laptop, I set the IP address to 192.168.0.20. The laptop can see the Windows XP machine, but Windows XP machine cannot see the Windows 7 machine. But this does NOT concern me. I want to move the files from my desktop (Windows XP) to Windows 7 (laptop). That's why I'm going through all this. The problem is that when I try to connect from Windows 7 to Windows XP machine, I get this window: I don't understand what username/password is needed. I use none on the Windows XP machine. I tried all usernames - no success. Please explain in deep details how to solve my problem so I can connect to my Windows XP machine. EDIT: Maybe this can help: the Windows XP machine is named 'I' and '???????? III' is the name of the laptop. Both computers share one workgroup - WORKGROUP.

  • How to stop intermittent playback on airtunes (iTunes + Airport Express)?

    - by Alex B
    Is there a definitive answer for how to stop intermittent "skips" or pauses while playing music from iTunes to an airport express connected to my home stereo? When I read other forums I see a wealth of posts that say "I did XYZ and it's fixed" followed by "I tried XYZ and it didn't work." This does not appear to be signal strength related. The green light on the Airport Express does not turn to yellow/orange. Other wireless devices have no trouble connecting at the same or greater distances from the wireless router.

  • Setup LAN to serve webpages and voip and access to the web site from inside LAN with domain name

    - by Mauricio Arias
    I'd like to know if it will work: I have my domain and I´m serving a webpage in a nginx to the internet, but if I type my domain in my laptop inside LAN I access to my modem/router configuration, I cannot access to the web server unless I type the IP address. I would like to add a Bind server after the modem/router - (port forward, ports 80 and 5060), if the request is www.mydomain.com bind should resolve the nginx IP address and serve it, and if it is a voip request should address to the voip server and if I'd like to access to the website from inside LAN I'd like to type mydomain.com. Could I do it with this configuration? Do I need something else? Thanks in advace!

  • Multiple vlan issue with procurve switch

    - by Chris-AZ
    I have a cisco asa5505 as my rtr/fw(10.1.3.254). I have vlan 1 and vlan 3. Vlan 1 is my default all access vlan. Vlan 3 is my Guest(dmz) vlan. I can't seem to get a dhcp ip address when my laptop is plugged into port 42 on my procurve. I have plugged my laptop directly into the firewall and it gets a dhcp ip fine(the firewall is dhcp server). the firewall is plugged into port 41. Only vlan3 needs to go over port 41. I'm sure I have a bonehead config problem however I'm about ready to pull out what little hair I have left. vlan 1 name "Computers" forbid 45 untagged 1-41,43-44 ip helper-address 10.1.1.16 ip address 10.1.1.1 255.255.255.0 tagged 46-48 no untagged 42,45 exit vlan 3 name "Guest Wireless" ip helper-address 10.1.3.254 ip address 10.1.3.1 255.255.255.0 tagged 41-42,44-48 exit

  • Setting reply priority on Wifi network with QoS?

    - by Omega
    When using a Station and Access Point that support QoS over Wifi, is it possible to set the priority (= Traffic Identifier = TID = QoS channel) of the reply? For example when sending a ICMP ping request using a high priority (= QoS channel), is it possible to force the station to use that same priority (= QoS channel) when sending the reply? A related question: Is it possible to force the station into using a different QoS channel?

  • configuring two network interfaces in ubuntu 10.04.1

    - by Bill Smith
    I have got two NICs configured on a VM - each is tied to a specific network, one is a DMZ, the other is an internal network. I want MySQL to listen on the internal network only and Apache on the DMZ listening for HTTP and HTTPS. But as soon as I add the second interface I run into trouble. I can hit HTTP on either interface, but can not hit 3306 on the internal network for MySQL. Here's the config... could someone sanity check this please? auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.153.24.230 netmask 255.255.255.240 network 10.153.24.224 broadcast 10.153.24.239 dns-nameservers 8.8.8.8 auto eth1 iface eth1 inet static address 10.153.24.195 netmask 255.255.255.224 gateway 10.153.24.193 broadcast 10.153.23.223

  • Configuring VLAN's on two HP procurve switches

    - by pan
    Trying to route a new ISP (Microwave link) from one of my out buildings to my computer room and hence my firewall. Old ISP came direct into firewall. In the outbuilding the Microwave modem connects with cat5 to HP Procurve 2524 switch. Because this ISP is coming through my internal network, I plan on using a new vlan called "airspeed" only for this ISP traffic. Up until now I've just been using the Default_vlan on both HP switches (4108 + 2524). So far I've been unable to ping from my laptop to the ISP modem both of which are on the new vlan 2 ("Airspeed"). No traffic needs to cross from vlan 2 to vlan 1 so I've left the ports as untagged. I've used the subnet provide from my ISP as the new vlan 2 subnet. Can anybody see what I'm doing wrong here? I've added the configuration of both switch below. Rough diagram: Microwave modem (Gateway IP 77.75.00.49) | HP 2524 switch (port 24) | HP 2524 switch fibre link | HP 4108GL switch fibre link | HP 4108GL switch (port D1) | Laptop configured with IP 77.75.00.50 (for testing but will be connected to firewall) And my 4108GL config: ; J4865A Configuration Editor; Created on release #G.07.21 hostname "HP ProCurve Switch 4108GL" cdp run module 1 type J4864A module 2 type J4862B module 3 type J4862B module 4 type J4862B ip default-gateway 128.1.146.50 snmp-server community "public" Unrestricted snmp-server host 128.1.146.51 "public" Not-INFO snmp-server host 128.1.146.38 "public" vlan 1 name "DEFAULT_VLAN" untagged A1-A3,B1-B24,C1-C24,D2-D24 ip address 128.1.146.203 255.255.0.0 no untagged D1 exit vlan 2 name "Airspeed" untagged D1 ip address 77.75.00.51 255.255.255.248 exit Finally my 2524 config: ; J4813A Configuration Editor; Created on release #F.04.08 hostname "HP ProCurve Switch 2524" cdp run ip default-gateway 0.0.0.0 snmp-server community "public" Unrestricted snmp-server host 128.1.146.51 "public" Not-INFO snmp-server host 128.1.146.51 "public" snmp-server host 128.1.146.38 "public" vlan 1 name "DEFAULT_VLAN" untagged 1-23,25-26 no untagged 24 ip address 128.1.146.204 255.255.0.0 exit vlan 2 name "Airspeed" untagged 24 ip address 77.75.00.51 255.255.255.248 exit no aaa port-access authenticator active

  • Windows 8 unable to connect to WPA2 AES Wireless Network

    - by user170193
    I'm running Windows 8 and am unable to connect to my home wireless network. I've tried restarting the router, patching the drivers to the next version, patching the drivers to the last version, running windows update and patching the chipset drivers to the latest version. So far nothing has worked. My computer can get on the internet via USB tethering on my phone or an open WiFi connection, but it is unable to connect to my home WPA2 AES secured wireless network. It sees the network, attempts to connect, gets a limited connection and then drops the connection. All the other wireless devices in my household have no problems. I have the new Dell XPS 12, running Windows 8 using an Intel Centrino Advanced-N 6235 wireless adapter. I've refreshed windows twice now to try different driver configurations. I've tried uninstalling all the Dell software, I've tried uninstalling all the Intel software and reinstalling just the drivers. I've tried turning switching the ability for the Wireless driver to turn the computer off or on. I've tried setting up the connection manually from desktop mode. I've tried switching it on and off using the wireless button on the keyboard and in the software. So far nothing has allowed me to connect to the secured network. It just keeps getting a limited connection, dropping the connection and retrying. It's driving me crazy, any ideas, anything I missed? Thanks.

  • Windows user account just for accessing network shares on a Windows 7 machine

    - by Paulo
    I would like my Xbox (Xbmc) to access my Windows 7 shares without having Guest accounts enabled and without using my Administrator account login details. I have tried making it an account called Xbox and this works fine but the Xbox account appears on the login page for Windows. Is there a way to create an account that is purely for accessing shares without it appearing as a user account????

  • iSCSI connection timing out on ESX 3.5 against a NetApp storage appliance

    - by Jesse1973
    I get a timeout on iSCSI on different ESX hosts (3.5) at different times. It is puzzling, as both the ESX hosts as windows and other guests are experiencing timeouts. The iSCSI network is segregated on a private network. Here is an export of vmkiscsid.log from last night: 2010-02-10-12:30:38: iscsid: an InitiatorAlias= is required, but was not found in /etc/vmware/vmkiscsid/initiatorname.iscsi 2010-02-10-12:30:38: iscsid: LogLevel = 0 2010-02-10-12:30:38: iscsid: LogSync = 0 2010-02-10-12:30:42: iscsid: Login Success: iqn.1992-08.com.netapp:sn.101197719,default,192.168.73.2,3260,2001, 0x1 2010-02-10-12:30:42: iscsid: connection1:0 is operational now 2010-02-16-02:03:35: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-02:03:39: iscsid: connection1:0 is operational after recovery (2 attempts) 2010-02-16-04:02:27: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-04:02:32: iscsid: connection1:0 is operational after recovery (2 attempts) Should i edit the timeout value on the ESX host for iSCSI? This may work around the problem but will not solve it.

  • Check packet vlan tag using Tap virtual interface

    - by ankit
    Hi all, I am trying to learn how to implement virtual interfaces using the Tap driver. So far my understanding is that using the tap driver I can create a virtual interface and then have a userspace program attach to this interface to analyse the data coming into this device. Now what if I attach a cisco switch to my LAN interface using a TRUNK link, forward all the packets coming into the LAN interface to the virtual tap interface and then in my program attached to this interface do some coding to analyze the vlan tag in the packet and only allow certain vlans to be forwarded to the WAN interface ? Does this sound plausible or is there is flaw in my basic understanding ? Thanks for the help! ankit

  • Changing subnet-mask of class-c network host to 255.255.0.0

    - by Prashant Mandhare
    We have a existing class-c network with IP address range 11.22.33.44/24 (just for example). My domain controller has been configured within this subnet. So all servers within this subnet have subnet mask configured to 255.255.255.0. Now we have got a new subnet with IP address 11.22.88.99/24 (note that only last 2 octets have changed). I want all new hosts in this new subnet to join my existing DC. For this we have configured firewall properly so allow this. (so there is no issue with firewall). But initially I was not able to join hosts in new subnet in existing domain. Later I doubted on subnet mask used in domain controller (255.255.255.0) and for testing purpose I changed it to 255.255.0.0, it worked like charm, i was able to join subnet-2 hosts in subnet-1 domain. Now i am wondering whether it will be good practice to change subnet mask of a class-c network to 255.255.0.0? Can any issues arise due to this? Experts please provide your opinion.

  • Best free (or cheap) ASP.NET based CMS for a club/association?

    - by marc_s
    I've been looking for a simple, intuitive ASP.NET based CMS to handle my club/association site. It should be based on ASP.NET so I can add some extra specific pages offer a membership system, e.g. I want to be able to define members which can e.g. comment posts, while anonymous users can only read (no active participation) have features like news, forums, blogs, picture gallery be simple and easy to use I've been looking at GraffitiCMS: so far my favorite, but it has no forum, and no membership system, and no future, it seems - no development whatsoever in over a year :-( Sitefinity: had extreme trouble even getting it installed, and when it's finally up and running, I find it overly complicated and not intuitive at all Umbraco: same problem - hard to install, hard to get up and running, the intro videos on their site are only available to paying subscribers (what's up with that deal???)..... DotNetNuke: seems like a major overkill Community Server: seems like a major overkill - and seems to be more and more commercial, only Any others I've missed that I should have definitely looked at ??

  • Setting up Windows 2008 with VPN and NAT

    - by Benson
    I have a Windows 2008 box set up with VPN, and that works quite well. NPS is used to validate the VPN clients, who are able to access the private address of the server, once connected. I can't for the life of me get NAT working for the VPN clients, though. I've added NAT as a routing protocol, and set the one on in the VPN address pool as private, and the other as public - but it still won't NAT connections when I add a route through the VPN server's IP on the client side (route add SomeInternetIp IpOfPrivateInterfaceOnServer). I know I can reach the server's private interface (which happens to be 10.2.2.1) with remote desktop client, so I can't think of any issues with the VPN.

  • Automatically repair network connection when it goes down.

    - by Spines
    Every hour or so my wireless router goes down, and everyone connected loses internet for a couple minutes. If I right click on my network connection and choose repair, I usually get internet back quicker. Is there a way I can automatically have it try to repair the connection once it goes down? Can I write a program to do this if there isn't a built in windows setting? BTW I'm using Windows XP. EDIT:My router is a Linksys WRT110 with Firmware Version: 1.0.04, and I have cable internet. The signal is 100%. I live in an apartment complex and there are about 15 other wifi networks visible to me, not sure if that has any effect.
