  • WAN and LAN setup for IPv6

    - by neu242
    We just got a IPv6 /48 range (a gateway and an IP address) for our company, but I'm unsure about how to set it up. We use FreeBSD 8.4 (pfSense 2.1) as a router/firewall. Currently we have IPv4 setup with a WAN towards the internet, and a NAT-ed LAN behind it for office PCs. We want to keep the LAN network for security, and we want IPv6 addresses from the /48 for all office PCs (without NAT). The WAN is configured with the IPv6 gateway 1111:2222:3333::1/48 and interface address 1111:2222:3333::2/48. But when it's configured this way, I guess it's impossible to fit the LAN on a /64 within the /48? I believe I should configure the WAN subnet on 1111:2222:3333:1::/64 and the LAN on a subnet like 1111:2222:3333:2::/64. Is this something I can configure myself, or do I have to ask the ISP to configure that routing for me?

  • Hyper-V can't connect from host to guest via RDC

    - by Mark
    As the title describes I would like to connect via Remote Desktop Connection to my VM. I want to use it as a Dev-machine and therefore would like to work full screen, as far as I understand RDC is the way to go. I have created an internal network connection within Hyper-V, assigned it to my VM, set a static IP/Subnet on guest (Win7 Pro) and host(Win8.1 Enterprise). It worked good for the first couple of times but now it seems to be broken or I have to do odd enable/disable network connection "dances" to get it running. Ping also doesn't work always so it does seem as if the guest and host would be "disconnected".. Is there something I can do so that the network connection always will be established?

  • Can't access certain web sites - reset router, any ideas?

    - by IniTech
    EDIT: This problem was resolved by my ISP - had to do with damaged fiber in one of their locations. Thanks to everyone that helped. Not sure if this is the right site (I'm a StackOverflow user) so I thought I'd give it a shot. I'm having trouble connecting to certain sites on any of the 3 machines that are on my LAN. The following sites are returning "Problem Loading Page - The connection has timed out" Sourceforge.net CNet.com Microsoft.com OpenDNS.com even my company's webiste I was worried about possible malware/virus, but I don't think that is the case (given the inability to access my company's site and the fact that all 3 machines are having the same issues.) I've tried with IE8, FF, and Chrome I have reset my router (WRT54G) and my machine(s) multiple times. EDIT: It is also worth noting that this page spins constantly and no avatars show up (I'm assuming it is trying to access gravatar.com with no success.) EDIT: I have the same issues directly connected to the modem. So, any router config is probably not the issue I'm a programmer, not a network guy - any ideas?

  • Creating ip alias on bonded interface ie. bond0:1

    - by bobothechimp
    System: HP Proliant DL360 G5 running CentOS 5.4 Bonded interface is working fine for a long time. I just went to add an alias the way I always have on a regular interface, and on first check it works (pinging on the local box) but it is not accessable from outside (iptables is turned off). In addition with this setup the normal network response started to decline, hanging for around a minute before I could get a prompt on login. Here are my config files: [root network-scripts]# cat ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no [root network-scripts]# cat ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no [root network-scripts]# cat ifcfg-bond0 DEVICE=bond0 BONDING_OPTS="mode=1 miimon=100" BOOTPROTO=none ONBOOT=yes NETWORK=10.2.1.0 NETMASK=255.255.255.0 IPADDR=10.2.1.11 USERCTL=no [root network-scripts]# cat ifcfg-bond0:1 DEVICE=bond0:1 BOOTPROTO=static ONBOOT=yes NETWORK=10.2.1.0 NETMASK=255.255.255.0 IPADDR=10.2.1.12 USERCTL=no any thoughts?

  • Setting up virtual network in VMware workstation

    - by Saif Bechan
    I am playing around with VMware workstation and am trying to set up a small virtual network. I am having a little trouble with this I hope somebody can help me out. I want to have all the different virtual machines to have different internal IP adresses so I can ping them SSH etc, from within my windows machine. I am directly connected to the internet without a router, so using a bridged connection does not seem to work. The other options NAT and host-only do not seem to work also. I think i need to create a new adapter. I am testing this out with a virtual image of linux debain 5.0 lenny. I have WMware Workstation 7 with virtual network editor. Can anyone guide me in the right direction.

  • Network with bridge and port forwarding?

    - by rafek
    Hi! Below is my current (and planned) home network configuration. I would like to connect my non-wifi-capable desktop to my home network. The question is: HOW? What device do I need? The primary requiremen is that I need to be able to forward ports to my desktop. How would I achieve this? Is there something like "double port forwarding"? Could anyone please explain this configuration to me? Thank you in advance!

  • Same network same switch but computers can't talk "ping"to eachother [closed]

    - by Sue
    Possible Duplicate: How does IPv4 Subnetting Work? Each computer(all 2 of them) can ping the router but can't ping each-other and firewall is off. Same default gateway, IP address very similar (just two number away at end) but the subnet mask is different between these two computers. One ends in 192 the other 224. There is a switch between them that then connects to the router. Why can't the computers ping each-other?

  • Throttling bandwidth on a per group basis

    - by Robreylen
    I am wondering if it is possible to create a bandwidth shaping/throttling script that shapes traffic based on user group. That is, if user1, user2, are in user group group1, they will have 1mb/s download and 1mb/s upload, whilst if user3 and user4 are in group2, they will have 256kb/s download and 256kb/s upload. I've read a bit about this and I found some iptables and TC implementations of a per user solution, but I have not seen anything for a user group. Hopefully it can be simply implemented in form of a custom iptables rules and script running with TC or the like. Here is a script I was looking into that does a system wide throttle: http://atmail.com/kb/2009/throttling-bandwidth/ I assume it is possible to do user group throttling since it is possible for throttling on a per user basis. Thanks for any info you can provide for this question.

  • Download videos from youtube as I see it

    - by Sab
    This may seem a somewhat strange requirement : I want to download youtube videos as I see it. I know that I would have to capture the packets using a program like wireshark , and I do know that this is possible. So lets say I have 3 computers on my network and 1 smartphone. Lets say I view a youtube video on my phone. I now want this video to be recorded on any one of the computers so that I can see it later(record in the sense capture the packets so that I dont have to download it again and waste my bandwidth). Are there any programs which will do this for me? The reason I want this is I use IMediaShare to view youtube videos on my Tv. Now once I see a video if I want to see it at a later point of time I have to download the entire video again.

  • Why is Windows 7 not following all routes?

    - by GigabyteProductions
    My computer is connected to my secondary router that's running the 192.168.42.0/24 network and my computer also has a route that directs anything on that network to the router, but for anything on that network other than the router itself, it get's the ICMP response of Reply from 192.168.42.194: Destination host unreachable. (with 192.168.42.194 being my computer). Every other network works, like all of the internet, or addresses on my primary router like 192.168.1.*, just not on the 192.168.42.0/24 network... route print returns: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.42.1 192.168.42.194 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 192.168.42.0 255.255.255.0 On-link 192.168.42.194 276 192.168.42.194 255.255.255.255 On-link 192.168.42.194 276 192.168.42.255 255.255.255.255 On-link 192.168.42.194 276 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 192.168.42.194 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 192.168.42.194 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 0.0.0.0 0.0.0.0 192.168.42.1 Default =========================================================================== The only time anything is supposed to send an ICMP Host Unreachable response is when there's no route to it, right? So, why is my own computer sending that to ping or tracert when I have the route of 192.168.42.0 with the mask of 255.255.255.0? An IP address of 192.168.42.2 surely fits into that route. If I explicitly add a route for the IP address i am trying to access, it works, like: route add 192.168.42.2 mask 255.255.255.255 192.168.42.1 (the 192.168.42.1 right after mask is gateway, or the device to send the packet to so it can route it further), but why wont it work for the implicit route that's automatically on the table? I disabled my firewall, too (I use Comodo if anyone thinks this still serves as a problem). I'v even tried explicitly adding the gateway of 192.168.42.1 to the 192.168.42.0/24 route instead of it routing through 0.0.0.0's gateway, which is what On-link does. but that didn't work either, so it's not a gateway specification problem. If the host was really unreachable, it would be the router's IP address (192.168.42.1) sending that to me... This network is all of my creation, so there's no problem such as an administrator locking me out, because i am the administrator.

  • Windows 7 'Unidentified Network'

    - by Throdne
    So my internet was working last night before I went to bed and woke up to a computer that is showing unidentified network. I have tried multiple ways of fixing it. > route delete 0.0.0.0 > uninstalling drivers - restart - reinstall from downloaded drivers > ipconfig /release - /renew > static IP > speed & duplex from auto negotiation to 1.0gbps full duplex > and also changed my network address to no value to 1234567890ab (not in that order) nothing seems to work. I have Comcast internet and when I connect the computer to the modem it works perfectly. but when I connect it to my router again, Unidentified network. I know my router isn't faulty, because my macbook pro, server, NAS, iPhones, and iPads are still working. I have also tried moving the port on the router, still same problem. my router is a: Cisco Small Business RVS4000 motherboard: GIGABYTE GA-990FXA-UD3

  • Routing DHCP traffic over the internet

    - by rmanna
    i'd like to know if it's possible for the internet to be between a DHCP server and the network it's "assigned" to? so basically, something like this: -------------- ------------- ------------- | DHCP Server | | DHCP | | Clients | | |-----Internet-----| Relay Agent |------| 192.168.0.* | | | | 192.168.0.1 | | | -------------- ------------- ------------- the behavior i'm seeing is that the DHCP server is offering 192.168.0.* IPs and sending them back to 192.168.0.1, which it can't reach. i tried masquerading the packets sent by the relay agent but that doesn't seem to work. from what i've been reading, this is normal behavior since the DHCP server uses the GIADDR as the destination address for its OFFERs, and not the actual source IP of the packets it receives from the relay agent. sooo, given that my DHCP server needs to be "on the other side of the internet" as depicted above, how can i get this working? are there settings for dhcpd to do this or is creating a VPN containing the DHCP server and the relay agent the only way? thanks!

  • How can I determine the IP addresses allocated by DHCP on a router that I'm connected to?

    - by user234831
    This "router" is not a typical situation. I'm using my phone as a hotspot and can only configure a select number of DHCP options. I can manage the limit on how many devices/clients can use my phone as a hotspot. I have to select from a radio-button list with the options: 2,3,4,5, or 8 I can specify the DHCP starting IP address. In this case, it begins at 192.168.6.106 When I'm connected via WIFI to my phone, an ipconfig /all command shows me that the default gateway is 192.168.6.1 and my IPv4 address is 192.168.1.148. I have the luxury of connecting another device to the phone and that device was assigned 192.168.1.121. I've tried connecting to 192.168.6.1, hoping for some sort of router setup page that I'm used to seeing, but there is no such thing or maybe it's just a matter of incompatable operating systems. In summary, the "router" (phone) has an IP address of 192.168.6.1 and a DHCP server that begins at 192.168.6.106 and allows up to 8 connections. Normally, I would assume a range of 192.168.6.106 - 192.168.6.113, but connected clients are showing otherwise. How can I figure out which IP addresses are set aside by DHCP for clients?

  • Maximise network transfer speed of various applications

    - by Alex
    When using nc, scp, wget to transfer files between 2 machines on a dedicated 2Mbps link, I get speeds between 0.5 and 1 Mbps. However, when I use iperf -c 10.0.1.4 -t 20 -P 12 (for example) I can maximise the speed of the link (getting stable 2Mbps). Is there a way to make single stream transfers (such as those done by scp) to utilise all/most of the link? Some kind of tcp settings, or iptables...?

  • Defining a persistent static route on Mac OS X

    - by Charles Duffy
    How does one define a static route on MacOS X which persists through reboots? The only suggestion I've found on Google advises setting up a launchd service to run at boot, which seems like a horrible hack (does it survive a network restart without rebooting, for instance?) To set up the route I need temporarily, I can run the following: route add -net ${network} ${gateway} ${netmask} How would I make this persist?

  • Determining the State of a User using their Hostname

    - by PhpMyCoder
    Not sure if this is the right SE site. I figured this question doesn't belong on SO, but if you think it doesn't belong here either, I apologize. I've been looking into determining the location, specifically the state, of a user accessing my website. One of the options I've known about for a while is the GeoIP City Database, however this isn't the most cost effective solution and I'm cheap so I was looking for a less expensive way. Something that occurred to me was that my state was in the public hostname assigned to me by Comcast: (Dash Separated IP).hsd1.ma.comcast.net Could it be possible that other ISPs follow this same pattern of inserting the state abbreviation into their users' hostnames? I've been looking around for a list of hostnames for other ISPs, but I haven't found anything. Can anyone verify that this holds true for other major ISPs?

  • wireless to wired internet

    - by Mark T
    My wife uses an old computer which doesn't really like having an internet connection via a USB wireless adapter. I've tried several, and none have been satisfactory. The connection gets dropped often and it is frustrating for her. A wireless card also had the same trouble. Repositioning the computer made no difference. (Two laptops, nearby, connect just fine and stay up, so it isn't the router.) However, the computer always worked well when I had an Ethernet cable connected to it. I know there is a box which will connect to my wireless network and provide an Ethernet cable connection. But the terminology used is so complex, I can't tell what it is I really need. In case that wasn't clear, here it is in different words: What I need is just the opposite of a wireless router. My wireless router takes my cable modem's Ethernet connection and makes it available to wireless clients. What I want is a box which is a wireless client to my wireless router and provides an Ethernet cable connection that I can connect to any device. I need to know the right name for a box with such capabilities. If you know of some inexpensive examples, that would also be helpful. I'm running a wireless G network with a Linksys Router.

  • USB Wireless adapter that works with Windows 7 (32 and 64bit)

    - by Kjensen
    Can anybody recommend a USB wireless network adapter, that has Windows 7 drivers for both 32 and 64 bit? It also needs to reconnect to the network when the computer is brought out of sleep. I have three of these from earlier (from Allnet, trendnet and linksys), and just one of them has working drivers for Win7 64bit - but fail to return from sleep in a working state.

  • Share internet connection in OSX through existing wireless network?

    - by baloo
    It's easy to share your Internet with AirPort by checking "Internet Sharing" in the system preferences, but this option asumes you want to create a new wireless network. Is there an easy way to configure Internet sharing if you want to use an already existing network? I want my laptop to use the existing wireless AP and share its internet to other clients within this network. Tried manually running natd -interface ppp0 without luck

  • How can I disable internet for a specific interface in Windows 7?

    - by MGSoto
    I have two NICs on my machine, one which connects to my network and has my internet connection. The other connects to a buddy next doors network with his internet connection. I don't want Windows magically deciding which internet connection to use, I want it to use mine. I've had some success by blanking out DNS servers for his connection, but then I also lose hostname resolution on his network and I realize this doesn't solve everything 100%. How can I force Windows to use only my connection while avoiding the use of a router?

  • is there a way to prevent network manager from storing the password for a wireless network

    - by tolomea
    Our corporate wireless network uses continuously changing passwords with RSA tokens. So every time we need to connect to the wireless we need to enter a new password off the RSA token. For extra fun using the wrong password a couple of times in a row causes the users account to be locked. Network manager automatically stores and reuses the password, with the net result that it is constant getting my account locked. Is there some way to prevent it from storing my password for that network? Or perhaps someway to get the gnome keyring to not store it?
