• Why my router alows to connect to the internet only after plugging the cord to laptop?

  - by gennad

  Hi all! I'm using Ubuntu 10.10. I have D-link dir-320 wireless router. When I turn on my laptop Lenovo G555, I'm trying to connect to router by it's usually unsuccessful. But if I'll pull the ethernet cord from the router and insert it into my laptop, everything will work well. And if after that I'll pull the ethernet cord from the laptop and insert it into the router, my laptop connects to the router and it will have Internet access via wifi. How to make the laptop directly connects to the Internet after booting without switching the cord?

• WinXP workgroup, 3 routers 3 computers

  - by Silvera

  I have 3 computers with WinXP x86, and 3 Cisco 1800 series routers. I'm trying to create a workgroup so that the 3 computers can share files with eachother. They can ping eachother (without any internet connection), and the routers setup is correctly configured (with interfaces, ip adresses, and ports). But none of the computers can see eachother, even though they are on the same network. My first question would be - can it be done the way it is currently configured - and, if yes, how, or can anyone point me in the right direction?

• iptables rule on INPUT between 2 ethernet cards on the same host

  - by user1495181

  I have 2 eth cards on the same host. Both connected directly with LAN cable. I set eth0 with ip - 192.168.1.2 I set eth1 with ip - 192.168.1.1 I set this rule: iptables -A INPUT -p tcp -j NFQUEUE --queue-num 0 There are no other rules. (I ran iptables -X,-F) I send TCP syn packet ( with c++ program by using raw socket) from 192.168.1.2 to 192.168.1.1 In wireshark i see that the packet received on eth0, but the iptables rule (above) dosnt apply for this packet. when i sent the packet to remote host and apply this rule on the remote host than it work correct. So, i guess that this is due to the fact that both eth cards exists the same host. . I need to create iptables INPUT rule for local eth card (dest and src on the same machine ). I need it for simplify test. Did i guess the problem correct? is there a way to bypass this? Ps - connected them via switch didn't help. the rule wasn't applied. Run on Ubuntu. TCDUMP show the packet: 10:48:42.365002 IP 192.168.1.2.38550 > 192.168.1.1.34298: Flags [S], seq 0, win 5840, length 0 but logging of iptables like this, has nothing: iptables -A INPUT -p tcp -j LOG --log-prefix '*****************' iptables -A OUTPUT -p tcp -j LOG --log-prefix '#################'

• How to set local alias for a machine?

  - by Alex G.

  I would like to set an alias on my local PC for a network machine. I know that it can be done by adding an entry in the hosts file as long as the IP address of the machine is also specified. However, the problem is that IPs are dynamically assigned by a DHCP server so I don't know for sure the IP address. Is there a way to define just an alias based on the machine's network name? P.S.: I'm running Windows Server 2008 R2.

• why would resetting the Netgear N300 router fix my Win 7 laptop's slow wifi?

  - by rjnagle

  In the past day the wifi download speeds of my Win 7 HP 64 bit laptop have slowed considerably. I am trying to troubleshoot the problem and to figure out whether it's hardware related (i.e., is the Intel(R) Centrino(R) Wireless-N 2230 the problem?) or router related. I have a Netgear N300 router connected to my modem. I'm using Speedtest to measure my speed. First, during my problem state, my ipad can download and upload at normal speeds. It's only my Win 7 laptop which is having problems. Because my ipad downloads at normal speeds, that would tell me that the problem is specific to the laptop (either HW or SW). But when I restarted my Netgear router, the laptop wifi problems disappeared. That just doesn't make sense. If we know that one device can connect properly to the router, why would a laptop have problems? What are some possible reasons why this might happen? Also, during my problem state, I noticed that on my laptop upload speeds were faster than my download speeds. Anybody have a guess about what might cause upload speeds on one device to be faster than another? Is there any actions i could take (or options to enable) so this problem won't occur. (I initially thought my problem might be software related or memory related -- Norton AV or browser plugins. But even after I disabled everything and made sure memory footprint was minimal, the slowdown was still occurring -- and it solved itself altogether when the router was reset).

• Internet connection sharing windows server 2008 R2

  - by This is it

  I have one windows server 2008 r2, and that server has 4 network interfaces (3 private, 1 internet connection). I would like to share internet connection with other 3 networks. Windows server firewall should make logs of data that is transfered. It should not be possible to connect directly to private networks from internet. How could I do it? Edit: I tried with NAT in RRAS, but it doesn't work. Here is the configuration: Server: IP private:192.168.0.1 IP public: xx.xx.xx.xx client IP:192.168.0.2 Default gateway: 192.168.0.1 Public and private interface added in NAT section of RRAS.

• NAT via iptables and virtual interface

  - by Alex

  I'm trying to implement the following scenario: One VM-host, multiple guest VMs, each one gets its own IP-address (and domain). Our server has only one physical interface, so the intended use is to add virtual interfaces on eth0. To complicate our situation the provider uses port-security on their switches, so I can't run the guest interfaces in bridged mode, because then the switch detects a "spoofed" MAC-address and kills the interface (permanently, forcing me to call the support, which I'm sure will get them a little bit angry the third time ;) ). My first guess was to use iptables and NAT to forward all packages from one virtual interface to another one, but iptables doesn't seem to like virtual interfaces (at least I can't get it to work properly). So my second guess is to use the source IP of the packages to the public interface. Let's assume libvirt creates a virbr0-network with 192.168.100.0/24 and the guest uses 192.168.100.2 as IP-address. This is what I tried to use: iptables -t nat -I PREROUTING --src public_ip_on_eth0:0 -p tcp --dport 80 -j DNAT --to-destination 192.168.100.2:80 That doesn't give me the intended results either (accessing the server times out). Is there a way to do what I'm trying to do, or even to route all traffic to a certain IP on a virtual interface to the VM's device?

• Router intermittently failing

  - by nomen

  My old Asus router died a few weeks ago, so I thought I'd set up my Debian box to deal with routing my home network. I have a few complications, but I adapted my configuration from a previously working configuration, and I don't see why I am having intermittent problems. But I am having them! Every so often, my SSH connections to the router (and to the Xen virtual machines hosted by the router) just drop. I am unable to use the router's dns server. I can't ping the router. Etc. All of these things work most of the time, but break down intermittently, for a few minutes at a time. (I can provide more details, but I'm not sure what will be helpful) /etc/network/interfaces: # The loopback network interface auto lo iface lo inet loopback # Gigabit ethernet, internal network auto eth0 allow-hotplug eth0 iface eth0 inet manual # USB ethernet, internet auto eth1 allow-hotplug eth1 iface eth1 inet dhcp # Xen Bridge auto xlan0 iface xlan0 inet static bridge_ports eth0 address 10.47.94.1 netmask 255.255.255.0 As I understand it, this is sufficient to create the network interfaces, and even do some switching between Xen hosts and my eth0 interface. I installed and configured Shorewall to manage routing between the bridge and my internet-facing interface: /etc/shorewall/zones fw firewall net ipv4 lan ipv4 /etc/shorewall/interfaces net eth1 detect dhcp,tcpflags,nosmurfs,routefilter,logmartians lan xlan0 detect dhcp,tcpflags,nosmurfs,routefilter,logmartians,routeback,bridge /etc/shorewall/policy net all DROP info fw net ACCEPT info all all REJECT info /etc/shorewall/rules DNS(ACCEPT) fw net DNS(ACCEPT) lan fw Ping(ACCEPT) lan fw ... and so on, these all work, when the router is accepting traffic at all. /etc/shorewall/masq eth1 10.47.94.0/24 Also, the router is currently "working", and I checked on a problematic client: arp infrastructure infrastructure.mydomain (10.47.94.1) at 0:23:54:bb:7d:ce on en0 ifscope [ethernet] I tried it when the router was down, and I (eventually) got the same response. It took about 30 seconds to return, though.

• How can I get windows to release an IPv6 address

  - by Mark Robinson

  I have a windows system with an IPv4 address and an IPv6 address and I'm trying to figure out how to release my IPv6 address. I've tried ipconfig /release6 and I get this error An error occurred while releasing interface Local Area Connection : The system cannot find the file specified. An error occurred while releasing interface Loopback Pseudo-Interface 1 : The system cannot find the file specified. No operation can be performed on isatap.{6B874193-B28A-4446-B6E6-8ADAC22E5090} while it has its media disconnected. No operation can be performed on IP6Tunnel while it has its media disconnected. I still have my IPv6 address at the end. I can release IPv4 address using ipconfig /release

• Simple server status page hosted externally available for users

  - by Chris

  I am looking for any kind of script - can be asp or php or any other web language - that gives me the ability to log outages and the current state of the network for our organisation. This would be similar to any major Telco's "Network Status" page, but I just want to tell the user's out there if the systems are up and running and have a history of recent outages. This would be for our remote user's so they could go to a webpage (externally hosted from our main site) and see that we are currently having problems with our network. What are other people out there using?

• Limited connections to Ubuntu 12.04 server

  - by Luis M. Valenzuela

  I'm having a weird problem with my server. The server is inside my network, connected to a 3com switch which is connected to the router that handles the internet connection. The main purpose of the server is to host a php application. What's happening is that user 1 to 15 in the private network have no problems connecting to the server, when user 16 tries to connect a time out comes out and is unable to connect to the server. It's not just to the php application, but to any service from the server. When the 15 users are using the application, the server doesn't even answer to ping. I haven't set any special limit in Apache's ini file or MySql and the firewall is being turned off because the server is only to give service to the internal network. Is there a parameter in any of the network's card conf. files that might me causing this ? Or should I suspect from the router's or switches configuration ? UPDATE. Tomorrow, I'm gonna do some test on the server modifying two kernel params in : /etc/sysctl.conf The settings are: net.core.somaxconn which has the limit on simultaneous network connections to the server and kernel.shmmax which controls the amount of memory the system can use for managing connections.

• Any ideas why Ettercap filters aren't seeing packet data?

  - by Bryan

  I'm using an Ettercap filter to detect a query response coming back from a particular service on a remote machine. When I see a response from the service, I'm searching through the data in the packet to see if an offset is a specific value, and if so I'm changing the value at another offset. Trouble is, when I try this on a new virtual machine I built my Ettercap filter's no longer getting any data in the DATA.data variable available to it. if(ip.proto == TCP && tcp.src == 17867) { msg("Response seen!\n"); if(DATA.data + 2 == "\0x01") { msg("Flag detected!\n"); DATA.data + 5 = 0x09; } } The filter's getting applied to the traffic because "Response seen!" messages get printed out by Ettercap. However, "Flag detected!" messages do not. I think DATA.data is indeed empty because if I change my second "if" statement to check for DATA.data == "" then the "Flag detected!" message gets printed. Any ideas why this may be happening?! Also, if this is the wrong site to be asking questions like this, please let me know. I wasn't sure if it fit better here or somewhere like superuser or serverfault. By the way, this is a cross-post from StackOverflow... I should have posted on this forum instead I think. :)

• Switches with large MAC address table?

  - by user1290200

  Does anyone know which switches have a large MAC address table ? I see most switches having only 8K, but we need to store way, way more than that (hundreds of K). I know this may seem odd, but trust me, there's no other way we can make our setup work. The only thing we seem to be able to do is install Juniper routers that store up to 1M addresses, but that will get quite costly and we'd rather avoid doing that.

• Router won't connect to computer over cable

  - by yyy

  I have a Thompson 784 router that connects to the Internet. It works nicely enough. What is wrong is that I have a shielded Cat 5e cable that goes from my room to the router that's in a another room (~30 metres). Both ends are the same; both ends are done nicely; I've tested it with a cable tester and every wire connects. However, when i connect my computer to my router neither one will find the other. So would anyone be nice and please explain what is wrong. p.s.: I have tried many different cable ends (currently it on standard/A), the cable is tested both ways (as it should be) and yes I'm at my wit's end =(

• Planning office network [closed]

  - by gakhov

  I'm planning to setup my office network from scratch and want to ask professional opinions or tips. My office is connected to Internet with Cable connection (100Mb/s). The devices i would like to connect are VoIP Phone (RJ-11), TV (WiFi/LAN), 3 laptops (WiFi), a few smartphones (WiFi), iPad (WiFi), Kindle (WiFi) and, probably, MediaServer (WiFi/LAN). As you can see, the most load will be on WiFi connections (probably, even if TV supports WiFi it's better to connect it by LAN?). So, i need help to choose the best routers combination (or even one?) to support stable connections for all these devices and minimize the total number of routers/adapters. Any thoughts? Thank you!

• Identifying a CAT6 cable in a bundle

  - by Jon Tackabury

  We had a contractor wire up our office with all the cables leading back to a central location. The only problem is that he didn't label anything, so we have no idea which cables go to which room. One end of the cable is terminated in a wall-jack (in the rooms), the other end is un-terminated and will be punched to a patch panel. Is there a way to identify the cables without having to terminate them? We'd like to group the cables on the patch panel by room, but I don't want to crimp/punch each cable twice. Thanks!

• VLSM help required

  - by user68062

  I have confused myself following a VLSM tutorial and need to get my understanding confirmed, would this be the correct format, or am i away off again 172.31.0.0 VLSM this network address for as many subnetworks as possible, with no more than 14 hosts in each subnetwork. Show the subnet mask used. As the ip address is class b and contains 16 bits in the network portion, this means that we can have 2^16 = 65536 possible networks, to give each of these networks a maximum of 14 hosts we would use the subnet prefix \28 for each subnet. Is this correct? Thanks BB

• How to forward http traffic through a specific network adapter.

  - by user18129

  i have the following scenario. Two laptops are connected via a router through the Ethernet ports. These two computers need to be able to communicate together. One computer also needs to access the internet through a different adapter (i.e. we will taking these two laptops two various sites where by the most common type of internet access will be wireless).In isolation all of the various adapters work fine (i.e. the internal network works fine, and the wireless connects to the internet). However,we try to turn on all of the adapters at the same time,the following occurs: If we bridge the two network connections together on the "Server" -The internet connection doesn't work through the wireless If we don't bridge the connections The internet connections don't work It seems like http traffic is trying to be sent through the Ethernet adapter (which of course is not connected to an internet connection). How can we solve this?

• Change TCP wait for ACK timeouts in Win7/WinServer

  - by maseth

  Is there any possibility to change default wait for ACK timeout in TCP network on Windows 7 or Windows Server ? I'm using very slow network ( 1200 bps ) and want to tweak TCP. When using default parameters network stuck on multiple retransmissions . If I'm able to change the ACK timeout and tx window size I think that it would work. On Windows XP it was possible but cant find any document for Win7 and Win Server.

• Any consumer routers with Outgoing VPN support?

  - by Brian Lacy

  When I'm working at home, I need to be able to connect to three different outgoing VPNs, two of which happen to use the same internal IP addressing schemes (192.168.0.*). I also need a static address for my VirtualBox VM so I can connect to my testing web server. Are there any routers which will allow me to connect to multiple outgoing VPNs and assign different internal IP addresses through NAT? Is such a thing even possible, or are there alternate solutions available? Thanks!

• Wireless range extender throughput extremely slow.

  - by Alan B

  I've got a Belkin 54G router connected to the internet, and a Belkin range extender model F5D7132. I can get the range extender connected to the parent router SSID no problem, in repeater mode as opposed to access point mode. My Windows 7 laptop connects to the extender, which has a different SSID, and it connects with the full 5 bars. The issue is that when going through the extender internet performance is murderously slow, even getting the config pages of the extender or router is bad. When I connect directly to the router, all is well.

• Windows 7 laptop with two active network connections will not perform DNS AAAA lookup under certain conditions

  - by Jeff Loughridge

  My laptop has two network interfaces. The Ethernet interface connects directly to my provider's edge router. It obtains an IPv6 address via SLAAC. I manually set an IPv6 DNS server. The wireless interface connects to a CPE router that doesn't understand IPv6. If the wireless interface is disabled, I can reach the IPv6 Internet with no problems using the Ethernet interface. I run into problems when both interfaces are enabled and the wireless interface get its IPv4 DNS server via DHCP. Let's look at two scenarios. Wireless interface obtains IPv4 DNS server via DHCP - The CPE router (192.168.0.1) sends its address as the DNS server. In this scenario, Windows 7 will not perform AAAA lookups. The browser uses IPv4 transit to reach dual stack web sites. I can't reach IPv6-only web sites using domain names. I can reach IPv6-enabled web sites using IPv6 literals instead of the domain name. Wireless interface is manually configured with OpenDNS DNS server - Windows 7 performs AAAA lookups using IPv6 transit (via the Ethernet). Everything works fine. My dual homed set-up is definitely not standard. Still, the behavior is very strange to me. A valid IPv6 interface exists in my Ethernet interface. Why won't Windows attempt AAAA lookups in scenario #1? I've included the output of ipconfig /all and netstat -rn.

• Kill UDP port that has no process?

  - by Chocohound

  I can't bind to UDP port 500 from my code (yes I'm running w/ sudo). The port is reported as "already in use" (Mac os X), but doesn't have an associated process: $ sudo netstat -na | grep "udp.*\.500\>" udp4 0 0 192.168.50.181.500 *.* udp4 0 0 192.168.29.166.500 *.* But sudo lsof doesn't show a process on port 500 (ie sudo lsof -i:500 -P reports nothing). How can I unbind port 500 so I can use it again? I believe I have a bad VPN client that isn't cleaning up after itself, but I can't get rid of this without rebooting the machine.

• Stack Managed Switches over a distance

  - by Joel Coel

  We have several buildings with stacked switches, where the distance between the stacked units is considerable... separate floors, or at opposite ends of a hallway. They are 3Com switches that stack using cat6 cabling. These switches are coming up on 12 years old now, and as I look around at replacements it seems no one supports this scenario any more. Stacking switches want to use fiber links (it more for me to run and terminate the fiber stacking cables than to purchase the switch) or other custom cables that seem only intended to jump up to the next unit in a rack. What have others done to support stacking over a distance? I'm considering breaking up the stacked switches into separate managed entities and just bridging from the root switch in the buildings, but I'd really like to avoid that for what I hope are obvious reason. The closest thing I've found are from netgear that use hdmi cables for the stacking connection... I could try to support that by running an additional cat6 line and re-terminating both links into a single hdmi port, but I have concerns over that approach as well.
