• Setup shared internet connection on virtualbox with fixed IP

  - by Tom

  I am a web developer and until recently I have been using ubuntu as my OS. For many reasons, I have switched back to windows. I still want to keep my server on linux platform, so I setup my local server as a virtual machine. Everything works great, but i have a little struggle with the networking. Since I am working in different places and going around clients, I connect to all sorts of network with different settings. That means the possible IP range is very dynamic which causes issues when I work on my local server. At the moment I have a dynamic IP on my host and static IP on my guest. That way I can access the server from my host (by adding record to hosts file). I also have internet connection on the guest. But once i change networks, it does not work (assuming the network has different configuration). My question is, how to setup host-guest networking, so no matter what network I connect to, I can keep my static IP on guest, which is registered in hosts file on my host so I can access the webserver and also I will have internet connection on the guest? Hope it make sense. Thank you

• Why does the wireless network icon have a red X over it when everything seems to work?

  - by Kristo

  I booted my almost brand new laptop running Windows 7 this morning and noticed a red X through the wireless networking icon in the system tray. At first I thought something was wrong, but clicking on it shows a good connection to my wireless network. I had no problem getting here to post this question. I'm very new to Windows 7 so I have no idea how to troubleshoot this myself. Is there an actual problem here? Can I fix the icon so it doesn't falsely display an error (I assume that's what the red X means)? Here's what I know: I can get here to post this question. There's at least one unsecured network available that I'm not connected to. I can see a bunch of wireless networks, presumably from my neighbors' houses. There are no other computers turned on in my house right now. The device manager shows no problems with any devices. I can ping my default gateway, DNS, and yahoo.com with no problem.

• pfSense routing between two routers with shared network

  - by JohnCC

  I have a network set-up using two pfSense routers arranged like this:- DMZ1 WAN1 WAN2 DMZ2 | | | | | | | | \___ PF1 PF2___/ | | | | \___TRUSTED___/ Each pfSense router has its own separate WAN connection, and a separate DMZ network attached to it. They share a common TRUSTED LAN between them. The machines on the trusted network have PF1 as their default gateway. PF1 has a static route defined to DMZ2 via PF2, and PF2 has a static route to DMZ1 via PF1. There is NAT to the WAN but internal networks (DMZ1/2 and TRUSTED) use different RFC1918 subnets. I inherited this arrangement, and all used to work fine. I made a config change to PF1 (relating to multicast), and machines on DMZ2 suddenly could not talk to TRUSTED. I rolled the change back, but the problem persisted. What I guess you'd hope would happen is that TCP packets would go DMZ2 - PF2 - TRUSTED and on return TRUSTED - PF1 - PF2 - DMZ2. That's the only way I can see it would have worked. However, PF1 drops the returning packets. I've verified this using tcpdump. I've worked around this by adding static routes to DMZ2 via PF2 to the servers on TRUSTED, but some devices on there do not support static routes so this is not ideal. Is there way to make this arrangement work decently, or is the design inherently flawed? Thanks!

• Network problems that might be related to NAT

  - by nenne

  Hello, I have an odd setup where there is a router(Router 2) routing between network network 1 and network 2. One router(Router 1) with nat for internet access that routes between internet and network 1. There are people in both of these networks. All the clients in network 1 can access the internet, the clients in network 2 can access the clients in network 1 and can also access the router 1. Router 1 can also access clients in network 2. However, the clients in network 2 cannot reach the internet. I cannot think about anything in the routing tables that would hinder this, since Router 1 can reach the clients in network 2 and vice versa. Can it be that nat starts the session between router 2 and the internet site/machine instead of the client and the internet machine? Does anyone have any ideas? I have very little control over router 2(its basicly an ISP vpn net service) but full access to router 1. Its an ubuntu 10.04 with iptables for nat/firewall setup.

• System With Two Network Adapters [closed]

  - by Synetech inc.

  Hi, My system has a NIC (Marvell Yukon) built-into the motherboard, but I also have a D-Link (RealTek) card. I figure that using the D-Link and disabling the Marvell makes the most sense, though I'm wondering if maybe the built-in one has better throughput (not that my Internet connection is so fast). Also, I'm wondering about the merits of using both at the same time. My router has four ports and I have experimented with enabling and plugging both NICs into the router. I was able to connect to the Internet, but the pattern of usage seemed irregular (which adapter was chosen for the transfer and any given point). I also considered bridging the two, but am having difficulty in finding out what exactly creating network bridge does in the context of the Windows Network Connections window. I am familiar with the concept of connecting networks, so it seems to me that birding two connections on the same segment is pointless at best (and can cause problems like loops?) Does anyone have any tips on what to do if a system has more than one NIC and any clarification on the bridge option? Thanks a lot.

• Remote reboot of windows to knoppix

  - by user64452

  I am attempting to develop an Auditing application. This audit application will be employed on windows networks. The Audit will need to discover Hardware and software details of all machines attached to the network (including Printers) I do not want to have to install this application on each workstation. The audit app. needs to discover all the ip addresses of all the networked workstations. I have been prototyping this app for the last couple of months and have decided to try a new tack Is this possible? a). You have a windows network, min Windows XP sp3 and upwards b). Maximum of 100 Networked machines (if that matters) c). I need to remotely reboot each WINDOWS machine in turn on the entire network and get it to startup using UNIX, say knoppix for example! d). however the knoppix live cd is only available from one of the networked machines Questions... Morphology? Longevity? Incept dates? Cheers DD

• How to resume XMPP groupchat window in Irssi (using bitlbee)?

  - by mcnesium

  I use Bitlbee to chat in XMPP-networks within my IRC-client Irssi. This works great so far, and recently I started using XMPP Multi User Chats as an alternative to IRC-channels. I set up a channel using chat add <account> <[email protected]> in the &bitlbee control window, set chan <room> set autojoin true and entered /join #room in the &bitlbee window to join that groupchat. It then appears as a unique Irssi window in the status bar. This seems to work ok too, but with one exception: Since I idle in the channels 24/7 my irssi has to cope with the every-night-24h-DSL-disconnection by the ISP. After it automatically reconnects, it does kind of rejoin that XMPP-groupchat, but the traffic of the groupchat does not go back to the unique irssi window, but keeps flooding &bitlbee with messages from root telling me about a Groupchat Message from unknown JID <jid>: <message> - which is the traffic of the groupchat. The unique groupchat window is gone after the reconnect, and I will again have to go /join #room in &bitlbee to get it back. Even worse, the window number is unused before I rejoin the groupchat, and if I get a query from any network, the window nests in that unused window spot, so I will first have to remove that query from the spot, and then move the rejoined groupchat to that window number. I want my groupchat window to resume after the reconnect just like every other IRC channel too. How can I get this done? Any ideas?

• Hyper-V VM's cannot access Host resources, and vice-versa

  - by Agent

  I have several Hyper-V vm's running on this Win2008 R2 Server box, and up until a reboot of the host server, all the VM's were able to access shared folders on the host. Now, they can't even ping the host server. From what I've seen, I need to setup an Internal only network through Virtual Network Manager in Hyper-V. I set this up, then tried to enable the Microsoft Virtual Network Switch Protocol option in this Internal Only NIC, but I get popups saying: Your current selection will also disable the following features: Microsoft virtual network switch protocol Which is absolutely stupid, considering the protocol is what I'm ticking the checkbox to Enable! As of now, on the host, I have 2 NICs: Physical - This NIC on the host machine does have the MVNS protocol enabled Virtual Network Adapter - Created through Hyper-V Virtual Network Manager as an External type of network. Trying to enable MVNS on this NIC also produces the error above. I've tried enabling Client for Microsoft Networks on the physical NIC for IPv6, but everytime I do that, all the VMs lose Internet connectivity and I cannot RDP into them. Anything else I can try?

• Network Sniffing and Hubs

  - by Chris_K

  This will likely seem naive to the experts... but it has been on my mind lately. For years I've been using ntop and a cheap 4 port hub to sniff client networks to determine who's doing what -- and how much. Great way to see what's going on when they call and say "Geeze, the network seems really slow today." No need to bring in a managed switch (or access the existing one) and no need to configure spanning or mirroring. I just drop in the hub inline where I want to measure. Lately I noticed it is just about impossible to buy a real honest-to-goodness hub anymore. While looking for a new one, I had someone tell me that I should be sure to get a full-duplex hub or I'd only be seeing half the traffic when I monitor. Really? I've been using a crusty old Netgear DS104 all this time. No clue if it is half or FD. Have I really been understating my measurements? I'm just not bright enough about the physical layer to really know... Side note: Just ordered a Dualcomm Ethernet Switch TAP as a hub replacement. Seems like a nifty gadget. Any notes or tips about it would be welcome in the comments :-)

• Linux Centos 6 becomes unavailable from time to time - OS&network issue

  - by adoado0

  I am encountering following problem. There is one server (DL160 G5) running Centos 6.3 with default kernel 2.6.32-220.2.1.el6.x86_64 - at this point I'd like to add that issue appeared also at older version - 6.1 and older kernel (do not remember exactly which version). There is cPanel installed and from time to time it becomes unavailable (network connection). What I've checked is (via KVMoIP): load average is completely normal it does not lack memory or disk space when problem occurs no console notifications checked all access logs and there is no sign that it can be caused by a client script cannot even access local interface (127.0.0.1) or main IP address running tcpdump I can only see packets arriving to server - no responses all services seem to be running properly (mail,sql,http,ssh) checked crontab and all clients' crontabs too network port utilisation is low ( up to several Mbits) arriving packet rate is low - hundreds per second (according to tcpdump) console (via kvmoip) works fine, no lags there is no conntrack at this server there is no ipv6 at this server flushing iptables, unloading modules does not resolve problem restarting network does not resolve problem, no errors appear it also occurs when two sepearate networks are configured (and multiple gateways) as well as one IP, one default gw and one network is configured - so it seems network configuration independent it seems to repeat randomly (load,packet rate,bandwith usage,load independent) checked server with different rootkit detection tools - it seems to be clean server has been rebooted, it did not change anything there are no interface errors it apperas randomly can be once a week or several times per day It usually works fine after 1-15 minutes. What I can also check? It is definitely OS issue - there is traffic at interface only in one direction when problem occurs, can not even ping loopback. Any ideas? Recommended checks? Anything I did not checked above.

• Concurrent users with Quickbooks?

  - by airietis

  I work in a company with 3 people who regularly use the same Quickbooks file. However, they work remotely on different networks. I need to implement a solution that allows all three of us to access Quickbooks at the same time remotely (and each make changes at the same time). We have a spare desktop PC that can be utilized as a server. So, my question is: what is the cheapest and most hassle-free solution to solving this problem? I've considered using application cloud hosting, however, it is very expensive ($40 per user a month) and we are on a tight budget. Is it possible to install Quickbooks on my own server, and have them connect to it remotely? If so, what is the best way to accomplish this? Remote desktop protocol? Or is there a built in feature for this with Quickbooks Premier 2013? EDIT: As MDMarra mentioned, I am looking for a solution that offers true simultaneous access. Will using a dedicated server and having users connect to a VPN be a viable solution?

• What is the correct approach i should use for an application that requires amazon S3 uploads and SimpleDB data management?

  - by Luis Oscar

  I am developing an application for iOS and that is going smoothly, the problem is that I am very new at server sided things. I am totally confused about how to correctly use Amazon Web Services for this purpose. What I want to do is very simple. I want my application to be able to query a servlet hosted in EC2 to be able to retrieve pictures and data based on some criteria from S3 and SImpleDB respectively. Also the application should be able to upload pictures into a S3 bucket and register the information in the SImpleDB. My main concerns are security and costs, So far i was using Amazon Token Vending Machine but I haven't been successful when trying to customize it, and while researching I discovered that on the long run it is very expensive. The ultimate goal is to handle a "social" picture service for my iOS application. Being able to register new users, authenticate these users. See what permissions they have to which pictures from the bucked. And all this without having to worry about Third party people from accessing the private pictures of my users. Sorry for this question but I am really clueless about how to handle this... I have tried reading many articles but all these server stuff looks very scary.

• How do I setup routing for two companies with different Internet connections on the same LAN?

  - by Clint Miller

  Here's the setup: Two companies (A & B) share office space and a LAN. A 2nd ISP is brought in and company A wants its own Internet connection (ISP A) and company B wants its own Internet connection (ISP B). VLANs are deployed internally to separate the two companies' networks (company A: VLAN 1, company B: VLAN 2, shared VOIP: VLAN 3). With separate VLANs it's simple enough to use separate DHCP servers (or separate scopes on the same server) to assign the default gateway to each company's gateway for their Internet connection. Static routes can be created on each gateway to point traffic destined for the other company's VLAN or the voice VLAN so that all nodes are reachable as expected. However, I think this is a form of asymmetrical routing, right? (The path from node A1 to node B1 is not the same as the path back from node B1 to node A1). Can I set up policy-based routing to correct this? In that case, can I assign the same default gateway to every device on all VLANs and create a routing policy on a L3 switch to look at the source address and forward traffic to the appropriate next hop? In that case, I want the routing logic to go like this: If the destination address is known, forward the traffic (traffic destined for a different VLAN). If the destination address is unknown, forward the traffic to ISP A's gateway if the source address is on VLAN A; or forward the traffic to ISP B's gateway if the source address is VLAN B. Am I thinking about this problem in the correct way? Is there another way to solve this problem that I am overlooking?

• Network bandwidth usage dashboard?

  - by SkippyFlipjack

  I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)

• Bind9 not doing anything with forwarded query responses?

  - by Rykaro

  I have a Bind DNS server that is the local production DNS server and a Windows 2008 R2 domain controller which provides DNS for a lab environment with the domain xyz.lab. I've configured the Bind DNS to forward DNS requests for the domain xyz.lab to the Windows DNS server with this config: zone "xyz.lab" { type forward; forward only; forwarders { x.x.x.x; }; }; zone "x.x.x.in-addr.arpa" { type forward; forward only; forwarders { x.x.x.x; }; }; And Bind options are (the all_internal acl includes the subnets of both the production and lab networks as well as the loopback of the bind server): allow-query { all_internal; }; allow-recursion { all_internal; }; allow-transfer { none; }; notify no; minimal-responses yes; version "unknown"; Unfortunately, when I do an nslookup or dig on the bind server for a host on the lab domain, the request times out. The logs on the Windows 2008 DNS server show it receiving the query and responding to it and a network packet trace shows the query responses arriving at the Bind DNS server. The servers reside on the same switch with a router providing connectivity between the layer 3 subnets (production and lab are on different subnets) and there is a round trip time of between 3ms and 5ms on pings between the two servers, so I don't think there is an issue with latency causing a timeout of the query. In summary a query-response arrives back at the Bind server and the nslookup/dig times-out. Why does the Bind DNS not seem to be doing anything with the query responses when it receives them?

• Sizing Switches for Storage and Production

  - by Untalented

  Couple questions. Should you always completely separate the storage network switches from production switches or are VLANs fine to segment this traffic? Is there a golden rule here? How do you properly size a switch for your environment based on the specifications the manufacturer provide (Throughput, Forwarding Throughput, Stacking Throughput, Max Mac)? If you have two switch options and one has a maximum Mac address of 8,000 vs. another with 16,0000. What does this really mean to me? How do make sure one vs. another is sized properly for me? Besides VLAN and Jumbo Frame support, is there any other "Must" haves for a virtual environments production or storage networks? There is a wealth of knowledge on sizing SANs and such, but this seems equally important and it's quite challenging to find as much information. -- Just to add some tidbits of information for the environment. This setup above is referring to the data centers which supports two different locations which have about 100 users between the two in total. The storage traffic will be iSCSI and will be 3 ESXi Hosts and one SAN housing about 2.7TB of data. Since there is currently no storage network in place (no SAN), I'm having a hard time regarding #2 to really determine what backplane throughput and switch specifications will be sufficient.

• VPN: Disable class based route addition for Windows XP/Vista

  - by brgsousa

  Paraphrasing this SuperUser link: When you set up a VPN, the Windows default is to enable "Use default gateway on remote network." A new default route is added to the routing table pointing to the remote network's gateway, and the existing default route has its metric increased to force all Internet traffic to traverse the tunnel and use the remote network's gateway. All traffic uses the VPN, and traffic destined for the outside world is directed to the remote gateway. When the VPN drops, the route to the remote gateway is removed and the original default route is set back to the original metric. Unchecking "use default gateway on remote network" means that new default route isn't added, so Internet traffic goes out the local gateway, but a new classful route is added to the routing table, using the local adapter's IP, pointing down the VPN. Only traffic destined for the classful network of the local adapter goes down the VPN. This may not be what you want. Checking "Disable class based route addition" means that classful route isn't added to your machine when the VPN starts up, and you'll need to add the appropriate routes for networks that should be routed through the tunnel. But, the option "Disable class based route addition" is available ONLY for Windows 7. How can I do something like that for Windows XP or Vista since they don't have that option? I have searched about for that but, no solution yet.

• Windows Update broke Wirless driver - Can't get it working again

  - by private_meta

  I naively installed a driver update incoming from Windows Updates yesterday. That caused my Wifi on my Notebook (HP ELitebook 2740p) to break. The network is working as I tried it with my other mobile devices. When installing said driver, it told me that the installation failed. I tried to do a system restore, which did not help getting wifi connectivity back. The device said it was working, but did not get any wifi connection and did not discover any networks. What I tried next was to uninstall the device from my Device Manager and install either the current drivers found through windows, then I tried the same with the current drivers on the HP driver page. both of those attempts failed. It always tells me that installation failed when I uninstall and reinstall drivers. If I try to update the broken driver via internet, it tells me it is up to date, and in the device manager it still views as broken. Next, I 'played' around a bit and reinstalled drivers, and I managed to install drivers from 2012, and when trying to update drivers manually and picking drivers that match the device, it lets me choose between drivers from 2010 and 2014. 2014 would be the current one, picking the 2010 driver leads to the driver being accepted. However, no wireless network can be found. I'm pretty much out of ideas by now, short of reinstalling. The only option I can still think of was that the device broke at the exact moment I installed the new windows driver, but I find that a bit unlikely. Any help would be appreciated fixing this issue.

• Why host and vmware guests fail to get MAC of each other?

  - by Georgiy Nemtsov

  I have Windows 7 64bit host running VmWare Workstation 8 with two CentOS 6.3 guests. All guests adaptors are bridged with statically assigned ip's. Connectivity bitween host and guests was fine for many days running this setup. And today while I was working suddenly host and guests became unreachable for each other. While both host and guests could connect to internet and connect to other mashines in my networks. On guests arp -a showed for host ip address: ? (192.168.1.3) <incomlete> on eth0 On host arp -a showed for guests ip 192.168.1.19 00-00-00-00-00-00 192.168.1.20 00-00-00-00-00-00 All other arp records was OK. Deleting arp-caches didn't help neither on guests nor on host. After that I disabled and reenabled network adaptor on my Windows 7 host. And the problem was gone. arp -a now shows correct MACs on all instances. As I suppose the issue was about expiry of arp cache. For some reason host and guests couldn't get their MACs. Hope somebody knows what it is all about? I am preparing guests to work in production and don't want to face such problems in future! Also I was supprised while investigating this issue from another mashine that could connect both on guests and host. On that mashine arp -a showed same MAC for host and two guests.

• How many bootable partitions are possible to have on one hard drive?

  - by draiden

  This may not be the correct place to post this; if that's the case, just let me know and point me in the right direction please! I'm thinking of building a box that needs to be lightweight and portable, and would need to be able to boot multiple installations of windows. I am needing to have multiple installations so that I can, for example, plug the box in to the network at one location, boot in to that location's partition, and have full access to everything I would normally need to do on a computer that has already been set up on that network. Then, when I go to the next client, I would be able to do the same thing, with the new location's partition, and have all of those network settings, drive mappings, etc., available there. Obviously I'd need to go through and set them all up on the different locations/networks, I'm not expecting it to magically know where I am and what I'm doing. It would be like I'm carrying around a computer that is configured for each place I need to go in one little box, instead of having to have multiple computers or having to reconfigure all the settings and such every time I go to another client. Or is there an easier way to do this that I haven't learned of?

• 1 PC, 2 consoles (as in 2 monitors, keyboards and mice)

  - by ciuly

  I have this desire to "kill 2 birds with one shot". Currently, I have 1 server running round the clock, 1 laptop that runs about 8 hours a day, 7 days a week, and a desktop that runs about the same length of time. All 3 are ... old, to say the least. So there is a great need to upgrade (well, the server might handle its job for another year or so, but that only depends on how much time I have to put it to "work"). Now, I'm "dreaming" of only one PC. I'm thinking vmware's ESX. So there will be a VM for the server, a VM for the "laptop" and one for the "desktop". And obviously I'll have to somehow "link" a set of monitor/keyboard/mouse with one of the laptop/desktop VMs. The server doesn't need such things, obviously (it doesn't have them at this moment either). Is something like this possible? ESX is not a requirement, it's just something I found that answers part of my problems, but there still remains the 2 KVM set that needs connecting and "linking" to appropriate VM. Why I would want to do this? well, first of all, it's much cheaper to upgrade one PC than 3. Then, the power consumption is obviously lower. Plus the extra space.Plus it allows me to better separate networks and services. Thanks.

• setting up vpn server

  - by Lock

  I need help in visualising how to setup our VPN box when we move to our new network with Telstra. We have a safe@office 500P, which has a public IP and a private IP of 192.168.19.2. It is physically connected to our router, which has 4 different interfaces, one being 192.168.19.1. On the VPN box, we have a static route to forward everything to 192.168.19.1 which is the router, and from there it works out where to go. Now, we are moving to a Telstra WAN and things are setup a little differently. Our head office router has only 3 interfaces- 1 is for the link to the switch that has the fibre connection (so our route to the internet and other branches), 1 is for our 10.10.20.x network and one is for the local branch network. I really have no idea how to set this up as with the new setup, we will not have a port for it to plug into on the router. Could I just plug it into the 10.10.20.x network? Would I have to give it a public IP or can we just forward through the ports that it would use? Another suggestion was to VLAN our switch into two networks- one for the 10.10.20.x network and one for the network the VPN currently sits on (192.168.19.x), and setup the router to trunk between the port and the switch. Not sure how to do this. Sorry VPN's are definitely not my strong suit. Any advice appreciated!

• How to block access to addresses outside network (internet)

  - by devnull

  I have a homeserver, that is now connected to the internet with an own network device (ath0 - 192.168.1.x). It also has one more network interface (eth0 - 192.168.0.x). Soon I will get a second internet line that will be connected the second network. The server then has both networks with different internet lines available, but i only want it to connect to the internet on the old ath0 interface - not the new eth0 (192.168.0.x). Background of that constellation is that the new line has a volume-limit in traffic - the old hasn't and i need the new line for all mobile devices and laptops. The devices should be able to use the new network to connect to the internet and the server. The homeserver is a debian 6 with iptables and some already written rules for it. I need now a rule to block all outgoing internet access on the eth0 interface - i guess it could be something with --target != 192.168.0.0 but i did not succeed in finding the proper solution. Edit: found the solution: iptables -A OUTPUT -o eth0 -d 192.168.0.0/24 -m state --state NEW,ESTABLISHED -j ACCEPT With that setting, all traffic that uses the eth0 interface is only allowed if the destination is inside the network 192.168.0.x - all other traffic is denied .

• Automatic switching of network card when vm is moved

  - by spock

  I have two hosts in a pool and I used to be able to move the vm around and they will start without any problem. But after I played around with some network setting, which I don't remember what, I started getting "This VM needs storage that cannot be seen from that server" message. As you can tell I am a beginner with Xenserver. Here is the very simple environment: 2 host servers with their own local hard disk and network card. One is a Pool master. Problem: Power off a vm and move vm from one server to another, or clone one vm to the other server. It used to be able to start up right away. Now, I need to delete one of the network that does not belong to the server, then it will start. Otherwise, the above error msg popup. The two networks (one for each network card in each host) are in the Networking tab of the vm, as well as in the host's networking tab. I googled but all I got to empty the DVD drive, which is not the problem here. Thanks in advance!
