  • Window 7 image in vmware will allow network connection out but not http

    - by Ormis
    I am currently trying to create a set of images to deploy on my network, but I've run in to a snag. When I create my own Windows 7 image I can successfully use NAT for connecting to the network but whenever I try to access a webpage I get nothing. To be more specific, All firewalls/iptables are disabled on my host machine, my virtual machine, and my network. I can do lookups and all addresses respond correctly (i'm even using Google's DNS). On the host OS i have full connectivity. On the virtual machine I can ping any device I want and all addresses resolve correctly. Within a browser I cannot reach any page via hostname or IP. I feel almost like port 80 is being blocked but i can't find any reason this would be the case. If anyone has had this occur before, I would love some insight to the problem. I understand this question is a bit out of the norm for stackoverflow, but I've run out of ideas. Thank you for any help you can provide.

  • Any way to stop VMWare workstation from dropping SSH connections?

    - by oljones
    I have VMWare workstation 8 with a few Linux guests. I have had problems maintaining an active SSH connection to my VMs when they are in bridged mode. I first read that the onboard realtek network cards were not well supported so I bought a Intel Pro/1000 GT card. This supposedly had support. But this made no difference. Connections via SSH are active for about the first 3 minutes then hang and die. I have changed the TCP Checksum offload on the Intel and Realtek NICs, but this only works some of the time and even then not for very long. The best I could do was about 20 minutes before the connection was dropped. Any ideas?

  • Sonicwall 3500 (Creating VLANS for usage of multiple SSID)

    - by Thomas Chia
    I have an issue here. Here is my setup: X0 - STAFF network | X2 - AGENT network | X4 - Wireless AP (for multiple SSID) Okay, basically I'm going to set up the wireless AP to be broadcasting 2 SSID, STAFF-WIFI and AGENT WIFI. When connected to STAFF-WIFI, the users will be connected to the STAFF network, while connected to the AGENT WIFI, the users will be connected to the AGENT network. Can someone explain in details how to go about setting up this configuration? Thanks!

  • How to calculate CIDR notation from entries in a routing table

    - by febreezey
    I have some entries in a routing table that were created using longest prefix matching, and I have to use those entries to determine the a.b.c.d/x notation (CIDR). This is an example entry: 11001000 00010111 00010. That was calculated from the range 11001000 00010111 00010000 00000000 through 11001000 00010111 00010111 11111111. I know the range is from IP addresses 200.23.16.0 to 200.23.23.255, but getting the /x for the subnet # doesn't make sense to me. Anyone know how to properly go about calculating it?

  • Share the DVB card on windows 7

    - by Bashar Kernel
    I have 2 computers connected to a router and I have a DVB card in one of them. I want to use the one DVB card to feed both of them. I read about it and I know that I want to share the DVB adapter with the Internet Connection Sharing on the LAN network. But when I use the connection sharing, I lose my internet access I tried to use "Bridge Connection", but then I also lost my internet access too. Can any one tell me how to fix this problem? And how to view the channels (for example how to use the VLC)?

  • why would you create two different subnets on the same physical network?

    - by xirtyllo
    I'm working at a messy location, one of the strange (for me) things is that on the same physical network there are two different subnets. Specifically some computers will have 10.0.0.0/24 and some others will have 172.16.0.0/24. There is only one DHCP server, which gives IPs on the 10.0.0.0/24 range, and there are two internet gateways, one with IP 172.16.0.1 and one with IP 10.0.0.1 . To give an example, I can easily swap one PC from one subnet to the other just by changing its IP and gateway settings. I am trying to imagine why they created the network this way, and which may be the possible advantages and/or drawbacks of having two different subnets on the same physical network. Any thoughts?

  • How can I get my routers to forward ports correctly?

    - by Giffyguy
    My network currently looks like this (simplified): Note that Router #2 is connected to the LAN interface of Router #1. This should be familiar to anyone who has seen a standard static-IP setup with an additional firewall for a residence or other small building. Router #1 is actually my cable gateway, but since it is a fully functional router/firewall, I am going to refer to it as a router. Now, I need to open various ports in both firewalls for incoming communication to my server - port 80 is a good example. So I've opened up port 80 in Router #2, and so far all incoming traffic at the public IP X.X.X.129 is being routed correctly. The problem is that I also need my server to respond to incoming traffic at the public IP X.X.X.130 on the WAN interface of Router #1. Naturally, I can't just tell Router #1 to forward port 80 to another public IP. Port forwarding is only supported when the traffic is being directed to the LAN subnet. I am willing to restructure my network topology if required, with the following conditions: Router #1 cannot have its WAN IP reassigned - X.X.X.130 is mandatory. Router #1 cannot be moved or disconnected from the cloud. The server cannot be given a second IP address. I would prefer the server to have a private IP address - e.g. 10.0.0.10 I'd like to keep Router #2, but it can have a private IP - e.g. 10.0.1.10 Following these rules, I need to get my server to receive incoming traffic on port 80 from both public IP addresses. Does anyone on SU know if this is possible? So far my only theories have been to set up a static route on either router, or to somehow combine my two subnets into a single subnet.

  • Configure an Azure VM for Dynamic DNS for Cloud Services

    - by Adam
    I am trying to setup an azure VM with proper DNS to allow multiple cloud services to communicate across cloud service boundaries. As I understand it, I need to provide my own DNS server. I do not have any on-premise infrastructure, so I am trying to configure an Azure VM to act as my DNS. This SO question (http://stackoverflow.com/questions/21858926/azure-how-to-connect-one-cloud-service-with-other-in-one-virtual-network) is very similar to my setup. This article (http://msdn.microsoft.com/en-us/library/windowsazure/jj156088.aspx) describes my particular case: Name resolution between virtual machines and role instances located in the same virtual network, but different cloud services Here is what I have done: Created Azure Virtual Network and declared subnets for each of my cloud services. Created an Azure VM (Windows 2012 R2) with DNS enabled RDP to the VM and enabled the DNS role and installed features Added the appropriate NetworkConfiguration xml section to each of my cloud services .csfg files Re-deployed my cloud services I have verified that I setup the virtual network and networkconfiguration properly because my cloud service hosts are able to communicate with each other if I use the internal ips. However, name resolution doesn't appear to be working, and it doesn't appear that my cloud service roles can communicate with my DNS server. How do I configure my VM so that my different cloud services roles register themselves with my DNS server? EDIT: I think I am 1 step closer to getting this to work. The cloud services that I was using are in an old affinity group which is not supported by VMs, so I was unable to add my VM into my virtual network. I created a new VNET in a new affinity group with my VM added into it. However, I still don't know how to configure the azure VM's DNS server so that the cloud services register themselves for name resolution. Also, an added bonus guaranteed to get a +1 would be to explain if it is possible to register a DNS entry for the VIP for an internal endpoint of my cloud services so we can get load balancing. Thanks!

  • Does HP 8530w support Wifi 802.11n?

    - by FoxyBOA
    According to vendor site HP 8530w supports 802.11n draft mode. My Windows 7 tell me that network card is 5100 ABG and know nothing about N mode (guys from Intel forum mentioned, that 802.11N versions must ended with N letter, e.g. 5100 ABN). Not sure if it matter, but my laptop model id is #FU462EA. How could I check that my Wifi card compliant with 802.11n (I suspect that "draft N" could have two "special" meaning: doesn't work with 802.11n at all or requires special activation of the mode). Any hints are welcome.

  • Anytime I upload something, my internet slows down extremely. What can I do?

    - by Earlz
    Title says it all. For a bit more info though: Basically, I have Time Warner cable internet. My speeds maintain a stable 2Mbit/s upload and 20Mbit/s download with average ping times around 30ms. This crazy thing happens though when I upload anything. I went to upload a 200M file to my server today through sftp and my internet completely choked up. I speed tested it during this upload and my ping time was around 800ms, download speeds of 0.2Mbit/s and Upload speeds of 0.3Mbit/s. Note, I wasn't downloading anything during this time either. It is just straight upload. What is it that causes this phenomenon? My router is OpenBSD. Is there anything I could set up to fix this problem(by queues or some such), or is this a problem with cable internet?

  • How to stop a infinite running process(ztail) started by a ssh session after that session is closed

    - by Sanath Adiga
    I have a peculiar problem. My server supports multiple ssh session simultaneously, so that multiple admins can manage it simultaneously. We have a command which calls ztail to show the compressed log files and when the current ssh session is closed (without pressing ctrlc, to stop the tail command), the command should ideally stop working. But what I observed when I start a new ssh session is that the process ztail is still running in the background and consuming CPU, even though the previous session was closed. How can I determine when the session is closed, so that I can use that variable/flag to close/stop any commands initiated by that previously closed session?

  • Instant connection to wireless network but delayed internet access on Mediacom with Windows 7

    - by David
    I have Mediacom cable internet and their provided modem/wireless router a Cisco DPC3825. Each of the laptops experiencing the trouble have Windows 7 64-bit. When connecting to the wireless network each computer will take a second or two to connect and then toggle from "no internet access" to "internet access" however, no websites are accessible for about five minutes after connecting. After that, there aren't any problems. It happens on all 3 of the laptops I have available and none of them have problems on any other network. It seems like my phone doesn't have the delay issue when it connects. I've power cycled the modem/router along with a DNS flush. I have some of the DNS servers manually set to Google DNS addresses and one just default. I've contacted and had Mediacom support try all its tricks. They changed the SSID and password along with resetting the thing remotely a handful of times. It was installed just this month and seemed to pass the tech's checks upon installation. Nothing in the settings has been changed, but it's been exhibiting this problem from the get go. This guy seems to be having the same problem, but no solution was posted. http://www.dslreports.com/forum/r27372861-IA-Connection-to-Mediacom-wireless-Modem-no-internet- Help greatly appreciated.

  • Configuring vlans on Cisco SG200 series switch with Ubuntu server

    - by nixnotwin
    I created a vlan on Ubuntu with vconfig tool with 21 as id and eth1 as the host port. I connected eth1 to one of the ports on the swtich (GE23) as all ports trunk by default. In the webgui I created a vlan named test with the id 21 and I made GE2 are port as an access port. In port to vlan mapping I selected vlan 21 and added it port GE2 by selecting untagged option. I have assigned 192.168.1.1/24 as the ip of eth1.21 on Ubuntu. If I connect another cleint pc to GE2 port with a ip of 192.168.1.2/24 I cannot ping the server ip (192.168.1.1/24). Ping from server to client also does not work. I inspected packets that are sent out eth1 on the server and I could see the vlan 21 tag. And I connect the other end of the cable to a different Linux pc and inspected the packets but no vlan tags can be seen. What could be preventing me from getting vlans working? Edit 1 screenshots:

  • Two identical fiber optic broadband lines working as one

    - by Katafalkas
    I have been trying to find an answer to this, but all I can find is hobbyists trying to connect their Linksys devices to get some magic out of them. I am looking for a way I could combine two 100Mbit fiber optic lines into a single connection for our office. I assume it involves some Cisco learning or something similar. Do I need to configure some big router to load-balance the NATing in some way? I assume that many of you have done something similar and hope someone could share their knowledge or at least provide me some tips on how to do this.

  • Finding all domain names that resolve to the same ip?

    - by Janak
    Lately I've been tracking a spammer on craigslist. I recently discovered that he's added a new technique to his arsenal, he registered a whole bunch of domain names but they all resolve to the same ip address. Is there any way to take an ip address and get a list of all the domain names that resolve to that ip?

  • Wake On Lan for Fedora 12

    - by Toymakerii
    I have a fedora 12 box that I am using as a sandbox for web development and a few other toys. The box gets really hot so I would like it to sleep/hibernate when no one is using it, however most of the people connecting to the box will not be able to access it physically. Is it possible to set up a Wake On Lan that wakes up the machine when it detects an SSH connection? A google search didn't yield much information. (or atleast I wasn't smart enough to register it as useful!)

  • linux to linux, 10TB transfer?

    - by lostincode
    I've looked at all the previous similar questions, but the answers seemed to be all over the place and no one was moving a lot of data (100GB != 10TB). I've got about 10TB that I need to move from one raid to another, gigabit net, XFS file systems. My biggest concern is having the transfer die midway and not being able to resume easily. Speed would be nice, but ensuring transfer is much more important. Normally I'd just tar & netcat, but the raid I'm moving from has been super flaky as of late and I need to be able to recover and resume if it drops mid process. Should I be looking at rsync?

  • How to Set Linux Bonding Interface to Gigabit

    - by Kyle Brandt
    I have enabled Linux active backup mode bonding. Each interface is a gigabit interface, but the bond interface seems to end up at 100 Megabit: bonding: bond0: Warning: failed to get speed and duplex from eth1, assumed to be 100Mb/sec and Full. ... bnx2: eth0 NIC Link is Up, 1000 Mbps full duplex, receive & transmit flow control ON ... bonding: bond0: backup interface eth1 is now up ethtool apparently can't provide info on bond: sudo ethtool bond0 Settings for bond0: No data available So does this mean I am operating at 100 or 1000 Megabit (My guess is 1000)? If it is only 100, what options in the ifcfg scripts or the modprobe bonding options do I need to sett to make it 1000?

  • SOHO NETGEAR wireless router disconnects when downloading torrents

    - by Lirik
    I have a NETGEAR WGT624 router at home which dies when there is a heavy torrent load. I open up my torrent client and it downloads for about 5 to 10 minutes and it continues to increase the number of seeds (goes up to 70-80 seeds), but after that the router simply fails and I have to restart it in order to get an internet connection again. Is there any way that I can fix this? New router firmware? Change some router options? Feed it a cookie? Anything?

  • Looking for software to create a personal hotspot on Mac OS X (not using the built-in ability)

    - by Fred
    I got my nifty little MacBook Air today. Since I will be going on travel I was hoping to use my iPad 3G as screen extension with Air Display. It works being in a shared WiFi network. Sadly Apple is a bit restrictive on the tethering with their mobile devices such as the iPad. Now I read iOS 4.3 will enable the iPad to use tethered networks. But the feature will not be working for iPad 3G. I assume their big partner telecom companies fear everyone will quit their internet contract with them. So I want to create a personal hotspot on my MacBook and use it on my iPad. But the iPad is not able to use this network. The network is visible but not usable. On Windows there is this connectify program which lets the PC act as wireless router. Does anybody know a similar program for Mac which would turn it into a wireless router? Or is there something I don't see with Mac OS X's builtin features?
