  • Two network adapters on Ubuntu Server 9.10 - Can't have both working at once?

    - by Rob
    I'm trying to set up two network adapters in Ubuntu (server edition) 9.10. One for the public internet, the other a private LAN. During the install, I was asked to pick a primary network adapter (eth0 or eth1). I chose eth0, gave the installer the details listed below in the contents of /etc/network/interfaces, and carried on. I've been using this adapter with these setting for the last few days, and every thing's been fine. Today, I decide it's time to set up the local adapter. I edit the /etc/network/interfaces to add the details for eth1 (see below), and restart networking with sudo /etc/init.d/networking restart. After this, attempting to ping the machine using it's external IP address fails, but I can ping it's local IP address. If I bring eth1 down using sudo ifdown eth1, I can successfully ping the machine via it's external IP address again (but obviously not it's internal IP address). Bringing eth1 back up returns us to the original problem state: external IP not working, internal IP working. Here's my /etc/network/interfaces (I've removed the external IP information, but these settings are unchanged from when it worked) rob@rhea:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary (public) network interface auto eth0 iface eth0 inet static address xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx network xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx gateway xxx.xxx.xxx.xxx # The secondary (private) network interface auto eth1 iface eth1 inet static address 192.168.99.4 netmask 255.255.255.0 network 192.168.99.0 broadcast 192.168.99.255 gateway 192.168.99.254 I then do this: rob@rhea:~$ sudo /etc/init.d/networking restart * Reconfiguring network interfaces... [ OK ] rob@rhea:~$ sudo ifup eth0 ifup: interface eth0 already configured rob@rhea:~$ sudo ifup eth1 ifup: interface eth1 already configured Then, from another machine: C:\Documents and Settings\Rob>ping [external ip] Pinging [external ip] with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for [external ip]: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), Back on the Ubuntu server in question: rob@rhea:~$ sudo ifdown eth1 ... and again on the other machine: C:\Documents and Settings\Rob>ping [external ip] Pinging [external ip] with 32 bytes of data: Reply from [external ip]: bytes=32 time<1ms TTL=63 Reply from [external ip]: bytes=32 time<1ms TTL=63 Reply from [external ip]: bytes=32 time<1ms TTL=63 Reply from [external ip]: bytes=32 time<1ms TTL=63 Ping statistics for [external ip]: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms So... what am I doing wrong?

  • bluetooth GPS device in J2ME emulator / Wireless Toolkit

    - by hsmit
    I'm developing a j2me application for my mobile phone (a Nokia). I'm using WTK (Wireless Toolkit) to test my code. Because I'm using a GPS device via a Bluetooth connection, I would like to be able to extend the emulator with bluetooth possibilities. Has anyone experience with BT & WTK? according to this article there is no way to do it by default. Any other ideas?

  • Can't attach EC2 instance to Network Interface

    - by Ian Warburton
    When trying to attach a network interface, it says... No instances were found for this availability zone. My instance is in us-east-1c and my network interface is in us-east-1b. Is that significant? If so, how do I create the VPC in the same zone and if not then why this error? EDIT: I've re-created the VPC and the Network Interface is now us-east-1c and the EC2 instance is also us-east-1c. Same error message though!

  • Installing Win7 over PXE through Serva fails on Loading Network Resources

    - by Armand
    Trying to install Win7 OS to a Lenovo E335 with no DVD/CD. I have to do it either over PXE/Network or USB. Although I am able to get passt the installation menu of Serva, it fails on Loading Network Resources ... FAILED No NIC/Driver, ABORTING! This is the only log on the Serva Client PC and nothing on the Serva-server. Would appreciate if someone can tell me how to go pass this error. THe network card works fine, it has already loaded the Windows installation structure on a X: drive on the new laptop. Another detail: I am using a normal Ethernet Cable to connect the PCs. Should this be enough or a crossover cable is a must in this case?

  • "No active network adapters found" Hyper-V 2008 R2

    - by mnemosyn
    I fiddled around with the virtual network settings of my Hyper-V server, because Windows Update failed to run in the VMs. I set the flag that makes the NIC exclusively usable by the VM. Now, the host system tells me it has no active network adapters. What does that even mean? According to netsh, there are three enabled network connections. I tried to restart the NICs using devcon.exe (the correct x64 version), but that doesn't make any difference - still, devcon reports the NICs are there and they are activated?! Is there any way I can force the host to re-enable the NICs?

  • Windows - Use Local Service and/or Network Service account for a windows service

    - by user19185
    I've created a window's service that monitors files on a specific directory on our Windows OS. When a file is detected, the service does some file I/O, reads the files, creates sub-directories, etc. This service also uses database connectivity to connect to another server. My plan is to have the service run as the default "Local Service" account. Since I need to allow write/read privileges, which apparently the "Local Service" account does not do by default, I'm going to explicitly set "Full Control" privileges for the "Local Service" account on the folder that I'm reading/writing to and from. I believe the above is a good . My question is, for the folder that I'm reading and writing to, do I need to setup a "Network Service" role with full control access? I'm wondering since my service uses database connectivity to another server, if I'll need the "Network Service" account setup. I may be misunderstanding what the "Network Service" account does.

  • Need help diagnosing network performance issues

    - by tokes
    I am currently working in a developing country as a system analyst for a government department. My area of expertise is software projects, but I've come across a few issues with the network setup in my office. (Unfortunately, being a developing country, there's not a lot of professional help available for this sort of thing.) Most recently, I am trying to diagnose a problem with slowness on the network. Our office is connected to the internet via an ADSL wireless modem/router (called Router). The modem is connected via ethernet to a switch (called Switch). The modem also acts as a wireless access point (called Wireless1), though because it is in a room at the end of the floor, it's range is limited. There are ethernet ports installed around the office. The cables of these all lead back to the same switch. In closer vicinity to the bulk of the client computers, there is another wireless router that acts as an access point for those clients (called Wireless2). That router is connected via ethernet to a wall port, and therefore to Switch. There is also a Windows server which acts as a DNS server (called DNSBox) which is located in the same room and is connected directly to Switch. ---Internet----------| Router/Wireless1 192.168.10.1 ---------------| |----|=========| DNSBox | |-------------------- 192.168.10.4 --------------------| Switch |---Other clients---- | |-------------------- |----|=========| Wireless2 ------------------| 192.168.10.198 One final thing to mention about the network setup. All clients are configured with manual IP addresses. Their router/gateway is set to the IP address of Router, and their DNS server is set to the IP address of DNSBox (with a secondary IP set to an external IP - that of our ISP's DNS server). Here are the symptoms we are experiencing: Clients connected to Wireless2 AP experience slow and unstable connections to the internet. (Slow here is defined as speeds of ~1KB/s, though ping response times seem to be as normal.) Clients connected via ethernet to Switch also experience the same slowness. Clients connected to Wireless1 AP (i.e. connecting via wireless directly to the ADSL modem) experience normal connections to the internet. Clients connected via ethernet to Router (i.e. connecting via ethernet directly to the ADSL modem) also experience normal connections to the internet. I also tried to gauge the connection performance between two machines on the network via ethernet: A file transfer between two clients who were both directly connected to Switch was the fastest; A file transfer between one client directly connected to Switch, and one client directly connected to Router (which is directly connected to Switch) performed much slower; A file transfer between two clients directly connected to Router also performed slowly. Things I have attempted to diagnose the problem: Restarted Switch -- no change. We tried unplugging ethernet jacks from Switch 4 at a time and testing the internet connection. The thought here was that perhaps a client on the network has contracted a virus, and is possibly spamming the network with traffic? (Not very technical, I know.) Unfortunately we couldn't get any significant increases in performance using this method. There were a couple of times when it seemed to be better, but then the connection speed quickly dropped back to slow/dead pace. I didn't want to unplug all jacks from Switch because I was concerned that users might be affected or that I would re-plug in the jacks incorrectly (should I even be worried about that? a port is a port on a switch, right?) I tried swapping the ethernet cable used to connect Router to Switch -- no change in performance. I tried swapping the port used on Switch for Router -- no change in performance. Anyone got any ideas on what this could be? Should I be mentioning specific brand names/models of the hardware used? Virii outbreaks are common in this country/office -- what could I be doing to figure out if a virus is at fault? If it is a virus, it doesn't seem to be generating a lot of traffic to/from the internet, because a) I can still get a good speed if I am directly connected to Router / Wireless1 and b) our ISP data usage has not risen suspiciously. Thanks for your help! Update #1 Here are the specs of some of the hardware: Switch is an Edimax ES3132RL 32-Port 10/100 Rackmount Switch Router is a D-Link DSL-G604T Update #2 I just tried unplugging everything except a laptop and Router from Switch. Speeds are still slow. I guess that means that Router / Switch are not being flooded? It seems more and more likely that the cause is something to do with the interaction between Router and Switch. However, I still can't find any useful resources on setting the LAN speed for either (and I'm not well-versed in these advanced networking configurations).

  • WAMP, DD-WRT, Using DNSMasq to access multiple virtual hosts via aliases on local network

    - by christian
    I've updated my question to coincide with my progress I am attempting to configure WAMP on my development machine. I would like to use it in conjunction with DD-WRT's DNSMasq feature to access multiple virtual hosts via aliases (dev1.local,dev2.local,etc.) over my local wireless network. I have followed the following tutorial which allows me to setup virtual hosts and access on local network by ip addresses. http://www.logicspot.com/web-development-2/viewing-a-locally-hosted-website-with-your-smartphone/ I've got this up and running. For simplicity sake I'd still like to setup DNSMasq to connect via aliases. I have followed the following tutorial http://www.question-defense.com/2008/12/29/add-static-dns-entries-to-dd-wrt-router-firmware And the aliases load on my development machine, but I can not access via the aliases on my mobile devices connected to the local network. I can however access via IPs. Thanks for any help you can provide

  • Recommended ADSL/ADSL2 router that supports PPTP VPN dial-out, 802.11n and gigabit ethernet?

    - by Throlkim
    I'm looking for a new router to provide a VPN tunnel for my home network. My plan is to pass all internet traffic over a PPTP VPN provided by the router, which should ensure that the connection stays alive and only passes traffic over that protocol. I'm normally quite a fan of Draytek routers, and their 2710n does seem to feature VPN dial-out but it lacks Gigabit ports (though I can make do with that if the VPN support is good enough). Has anyone got any suggestions or personal experience in a similar setup? I'm happy to consider anything that supports dd-wrt (as I believe that supports VPN-out, though I may be wrong). Bonus points for models available in the UK.

  • Mac OS X: How do I disable SSID Broadcasting with Internet Sharing over Airport?

    - by Jack Chu
    I'm currently using Internet Sharing from my Ethernet over Airport on my Macbook Pro, however I don't want my SSID broadcasted†. There doesn't seem to be an option in Sharing/System Preferences to hide my ssid or prevent broadcasting. Any ideas? † My parent's restaurant has a wifi router, but it's on the roof level where the cable was installed. The signal it gets is weak, but works for the macbook. Their iPhones and 802.11G based computers can't get the wifi connection, maybe 802.11N on the macbook gets better penetration. I figure they could use the airport sharing from the laptop. For a restaurant type setting I don't think having WPA or WPA2 is super important. There's nothing sensitive or insecure on the network, so I figure hiding the SSID would be good enough for their purposes. It's not even active 100% of the time.

  • Windows Service and Group Policy unable to access network share on Win2008 Domain

    - by Terence Johnson
    I have one computer on my domain that has suddenly stopped receiving software updates via group policy. Domain logins still work, and group policy on the machine is still being updated, so it knows that there are new packages to install and where to look for them, but every time it tries to install a package, it throws a 1622 error (location not found). Logged in users can reach the same network shares, and every other computer on network is installing the packages. Further investigation found that other services running as "System" on the problematic computer are also unable to authenticate to network shares. How do I diagnose/fix this computer's account in Active Directory? The computer account exists, and is a member of "Domain Computers" - or is there something else I should be looking at?

  • Remote Desktop, Host: 2008, Client: Windows 7, The remote computer requires Network Level Authentica

    - by deerchao
    Hi, today I accidently changed one option of Teminal Services, I checked "Allow connections only from computers running Remote Desktop with Network Level Authentication". After that, I can't connect to my server any more. The error says: The remote computer requires Network Level Authentication, which your computer does not support. But my client pcs(both home and at office) are running Windows 7, as far as I know, it shoud support NLA; And in About dialog of Remote Desktop Connection there says "Supports Network Level Authentication". My server is running Windows Server 2008, placed in IDC center; I could connect to it before I change the settings. All other sevices(like IIS, SQL Server) are running normally. For clients, I tried two PCs running Windows 7, and two virtual windows XP machine running in Virtual PC and Virtual Box, all of them gives the same error message. Is there a way I can make things right without go to IDC which is far away? Thanks.

  • Network issues with DNS not being found

    - by Anriëtte Combrink
    Hi there This is exactly like how our network looks like: Single server with a network router Everything is setup, but I cannot connect our Macs under the Login Options - Join... to this server. Our server's name is Toolbox and I have tried Toolbox.local, Toolbox.private, prepended the afp:// protocol to the name, but nothing, our Macs just don't want to connect this way. Our router has DHCP and gives out all the IP addresses naturally, would I have to add Toolbox.local to the DNS on the router and like it via static internal IP to the server? Our Macs keep giving the following error while trying to join the Network Account Server: Unable to add server Could not resolve the address (2200) What am I doing wrong?

    I am desperately needing a solution to binding certain applications to specific network interfaces. ForceBindIP seems to be my only solution. Although the website claims it works up to XP, Google says that many users running 7 have had it work successfully. I have UAC disabled, yet still: Does anyone know why this is happening? If not, does anyone know a viable alternative to ForceBindIP? I'm a gamer and I'm addictively trying to torrent on a secondary connection while playing games online.

  • Is is possible to change MAC address of a WiMAX USB adapter?

    - by Salman A
    Wondering if it is possible to change the MAC address of a WiMAX USB adapter (read WiMAX, not Wi-Fi) manufactured by Motorola, ZTE, Intel etc. I've tried a few tools that did changed the MAC address of the adapter to another valid MAC address (that I coped from another equipment made by same company) but then I was not able to connect to the network, the connection software took long time stating "obtaining IP address"; then few seconds after it got one said "lost IP address". Wondering if changing MAC address of such devices actually work.

  • What is the difference betweeen "Network install" and "Network Boot" options in virt-manager when installing a new virtual machine

    - by Marwan
    From my understanding of PXE (Preboot Execution Environment), I know that there must be some negotiation first between the booting client and a DHCP server to obtain network parameters (IP address, etc) in order for the client to be able to fetch the boot loader and kernel image from the boot server. In other words, and aside from being a "virtual" machine, we're talking here about a "bare metal" machine, so there must be some "pre boot" mechanism for those negotiations to take place, and this is exactly what PXE is all about. When I think about the "Network install" option, I can't figure out how the new VM would be able to fetch the boot images (bootloader and kernel) without the previously mentioned mechanism. So, here is a short version of the question: When provisioning a new virtul machine, how do you expect the "Network install" option in virt-manager to work behind the scenes? Many thanks.

Here is what is in the batch file: @echo off net use * /delete /y net use b: \\Server\Share /user:DOMAIN\Username password exit When the computer is restarted or logged off and back on, the task runs fine (according to the scheduled tasks window saying when it ran last) but the mapped drive doesn't show up. I'll open the command prompt and type "net use" and it simply says "There are no entries in the list". If I then right click on the task and run it, it works and the mapped drive shows up. I've checked the log and nothing shows up. I've tried adding a timer in the batch file so it waits 10 seconds (ping 1.1.1.1 -n 1 -w 10000nul) thinking that maybe the network wasn't connected, but that didn't work. What else can I try? Thanks!

  • Thinking of Powerline adapters for networking

    - by Henderson McCoy
    will powerline work as good as wifi I am now in a large house (renting a room) and the router is in the front of the house and I am in the back. Don't know if wifi will have the range and stability so I am looking at all the alternatives from running a long cable to powerline. looks like a powerline adapter set will cost about $50 http://www.bestbuy.com/site/Actiontec---500-Mbps-Powerline-Home-Theater-Network-Adapter-Kit/5215483.p?id=1218625358741&skuId=5215483 has anyone use these or other powerline adapters? how is powerlines speed? Are they more stable then wifi? powerline cost is good i am just currious about the performance

  • Network bottleneck/throttling issue

    - by Gavin
    Hi all, It's my first day at a new company and i've been given the task to find out an issue with the internet connection. I noticed that whilst I was downloading a large file, the network grinds to a halt, except for my download. At first I thought it was the internet connection/modem but it seems that whilst the lockdown occurs, I am unable to access any network device. Has anyone experienced this before and if so, do you have any pointers? Looking at the setup. They have an DSL modem that connects to a 10/100 switch. There are only 5-6 computers on the network. Cheers Gavin
