  • NAT for Sprint Nexus S "Portable Wi-Fi hotspot"

    - by Jon Rodriguez
    I am on a 2010 Macbook Air connected to the web over wifi tethering on my Sprint Nexus S. I want to be able to host a few files using MAMP, but it seems that Sprint is running a NAT. When I query checkip.dyndns.org right now, it returns 68.27.228.75. However, trying to navigate to that IP fails (even though I do have MAMP's Apache running on port 80, as verified via loopback). When I whois 68.27.228.75, it appears to be a Sprint address, with NetName "SPRINTPCS" and OrgName "Sprint Nextel Corporation". So, is there some way I can circumvent Sprint's NAT to allow people to connect to my server that is running on a Nexus S Portable Wi-Fi hotspot?

  • DHCP not working after NetBIOS over TCP/IP disabled

    - by user27515
    I want to disable the "NetBIOS over TCP/IP" device in the device manager to free port 445. But after doing that my Internet stops working. I'm connected to a WLan router using DHCP on WinXP, and it is stuck forever in the "acquire network address" step. Why does it misbehave like that? I don't need NetBIOS!

  • redirect from mysite.com to www.mysite.com

    - by jml
    hi there, i know that this has been answered many many times, so if someone wants to point me to another thread that answers my question specifically, that is fine... for right now, my searches aren't yielding many results. so i have a website like mysite.com that has a flash swf embedded in it and i go to www.mysite.com ... all of the sudden, things don't work properly. i would like to get to the bottom of this, because it's not like the page just "doesn't load" at all; it loads and i can only do certain things; as if certain functionality is disabled (might be url requests for specific urls etc). do i need to manage this in my control panel? i wouldn't assume so, because the site loads; just has a crippled functionality from within the swf. i was thinking it might have more to do with my crossdomain.xml file; could this be the case? thanks for any tips or suggestions.

  • Connecting together DIR-615 and DIR-655

    - by ra170
    On my DIR-655 my internal network is: 192.168.0.x On my DIR-615 my internal network is: 192.168.1.x They are both connected to my firewall PIX 501 box The PIX itself is connected to the comcast modem. I briefly looked at the menu options on those router and they look similar, however I'm not sure what's the best way to connect those two together so that I can go between those networks. (printing, file browsing, etc.) I'm not sure if I have to do this somehow on those two router or on the PIX itself, or probably on all of them. If anyone has experience with something like that please let me know..

  • DrayTek Vigor 2920(n): VPN with VLAN restrictions?

    - by Dirk
    Hi, I'm currently installing a DrayTek Vigor 2920n router in a new office. This router is to be used for 2 seperate companies. For one of these companies, the router has a LAN-2-LAN (VPN) connection to a datacenter configured. The other company should not be able to access this other (VPN-)network. I'm aware of the capability of this router to have VLAN's, but I cannot figure out how to configure the VPN-connection to only be accessible for VLAN0 and not for VLAN1. I know I can also add another router to physically split both networks, but we bought the DrayTek with the idea that it could easily have the VPN-connection available for VLAN0 and not for VLAN1. VLAN1 can easily be in another subnet, that's fine, although, I don't know how to configure that on this DrayTek. Can anyone point me in the right direction? Thanks in advance, Dirk

  • How can I prevent OpenVPN from clobbering local route?

    - by ataylor
    I have a local network on 192.168.1.0 with netmask 255.255.255.0. When I connect to a VPN though OpenVPN (as a client), it pushes a route for 192.168.1.0 that clobbers the existing one, making my local network inaccessible. I don't to access anything on 192.168.1.0 on the remote machine; I'd like to just ignore it, while accepting the other routes that are pushed. My client is Ubuntu 10.10. How can I skip the one offending route?

  • TCP/IP networking working as expected, but can't access Windows Shares

    - by Pablo Santa Cruz
    I am trying to fix a Windows 7 Pro SP1 (32 bits) computer. I have a weird problem. It was working fine until two days ago (didn't do anything weird in that day), and suddenly windows network (accessing to Windows Shares, sharing my printer) stopped working. TCP/IP networks words without issues, since I can IM, use the WebBrowser, check my email, you name it. Any ideas on how could I attempt to fix this?

  • Route packets from one VPN to another

    - by Mike
    I have two OpenVPN servers (10.8.0.0 and 10.9.0.0) set up on my OpenSUSE server. Within one network, each computer is visible to any other one, but I'd like to make it so that computers are visible across networks. I'd like to route the packets like this: when a user (say 10.8.0.6) pings an address on the other VPN (10.9.0.6), the packets are routed to the 10.9.0.1 and then to the appropriate computer in this VPN. How do I achieve this using iptables or a different tool? I tried the commands at the end of this section with no avail.

  • Baidu spider is hammering my server and bloating my error_log file

    - by Gravy
    I am getting the following errors in my /etc/httpd/logs/error_log file [Sun Oct 20 00:04:15 2013] [error] [client 180.76.5.16] File does not exist: /usr/local/apache/htdocs/homes [Sun Oct 20 00:08:31 2013] [error] [client 180.76.5.113] File does not exist: /usr/local/apache/htdocs/homes [Sun Oct 20 00:12:47 2013] [error] [client 180.76.5.88] File does not exist: /usr/local/apache/htdocs/homes [Sun Oct 20 00:17:07 2013] [error] [client 180.76.5.138] File does not exist: /usr/local/apache/htdocs/homes These kinds of errors are so often, that my error log files are over 500MB! I have done an IP trace on the client address to find that it belongs to something called baidu. Beijing Baidu Netcom Science and Technology Co in China. Is there a way that I can just get apache to deny any incoming requests from some crummy spider that is repeatedly hitting my site??? Is there a better way of dealing with the problem? I am happy to completely block out China if it means that I can actually track real errors.

  • Limiting interface bandwidth with tc under Linux

    - by Matt
    I have a linux router which has a 10GBe interface on the outside and bonded Gigabit ethernet interfaces on the inside. We have currently budget for 2GBit/s. If we exceed that rate by more than 5% average for a month then we'll be charged for the whole 10Gbit/s capacity. Quite a step up in dollar terms. So, I want to limit this to 2GBit/s on 10GBe interface. TBF filter might be ideal, but this comment is of concern. On all platforms except for Alpha, it is able to shape up to 1mbit/s of normal traffic with ideal minimal burstiness, sending out data exactly at the configured rates. Should I be using TBF or some other filter to apply this rate to the interface and how would I do it. I don't understand the example given here: Traffic Control HOWTO In particular "Example 9. Creating a 256kbit/s TBF" tc qdisc add dev eth0 handle 1:0 root dsmark indices 1 default_index 0 tc qdisc add dev eth0 handle 2:0 parent 1:0 tbf burst 20480 limit 20480 mtu 1514 rate 32000bps How is the 256K bit/s rate calculated? In this example, 32000bps = 32k bytes per second. Since tc uses bps = bytes per second. I guess burst and limit come into play but how would you go about choosing sensible numbers to reach the desired rate? This is not a mistake. I tested this and it gave a rate close to 256K but not exactly that.

  • Strange requests coming from Korean Site

    - by Jim Jeffers
    Lately I've been finding a lot of strange requests like this coming to my rails app: Processing ApplicationController#index (for 189.30.242.61 at 2009-12-14 07:38:24) [GET] Parameters: {"_SERVER"=>{"DOCUMENT_ROOT"=>"http://www.usher.co.kr/bbs/id1.txt???"}} ActionController::RoutingError (No route matches "/browse/brand/nike ///" with {:method=>:get}): It looks like it's automated as I get a lot of them and notice the strange parameters they're trying to send: _SERVER"=>{"DOCUMENT_ROOT"=>"http://www.usher.co.kr/bbs/id1.txt??? Is this something malicious and if so what should I do about it?

  • how to pass traffic for port 80 not through openvpn?

    - by moti
    Is there a way to configure OpenVPN clients to route traffic for HTTP port 80 and HTTPS port 443 directly (i.e. not through the VPN), but through the regular default gateway the clients have. All other traffic should go through the VPN. My client is running OpenVPN on Windows and my current configuration looks like this: client dev tun proto tcp remote my-server-2 1194 resolv-retry infinite nobind persist-key persist-tun ca ../keys/ca.crt cert ../keys/client1.crt key ../keys/client1.key ns-cert-type server verb 3 route-metric 1 show-net-up dhcp-renew dhcp-release route-delay 0 120 hand-window 180 management localhost 13010 management-hold management-query-passwords management-forget-disconnect management-signal auth-user-pass

    Is there any way to connect the root of a domain name to a dyndns account? This question reveals how to get www.whatever.com to point to dyndns, but is there a way to get whatever.com itself to point to it? The domain is registered with GoDaddy if that matters.

  • OpenVZ multiple networks on CTs

    - by picca
    I have Hardware Node (HN) which has 2 physical interfaces (eth0, eth1). I'm playing with OpenVZ and want to let my containers (CTs) have access to both of those interfaces. I'm using basic configuration - venet. CTs are fine to access eth0 (public interface). But I can't get CTs to get access to eth1 (private network). I tried: # on HN vzctl set 101 --ipadd 192.168.1.101 --save vzctl enter 101 ping 192.168.1.2 # no response here ifconfig # on CT returns lo (127.0.0.1), venet0 (127.0.0.1), venet0:0 (95.168.xxx.xxx), venet0:1 (192.168.1.101) I believe that the main problem is that all packets flows through eth0 on HN (figured out using tcpdump). So the problem might be in routes on HN. Or is my logic here all wrong? I just need access to both interfaces (networks) on HN from CTs. Nothing complicated.

  • Problem linking two Cisco routers with a static route

    - by Chris Kaczor
    I'm trying to link two Cisco routers with a static route and I haven't been able to get it working as expected. Here is the basic setup: Router 1 - WRV210 - 192.168.1.1 - connected to cable modem Router 2 - RV120W - 192.168.2.1 I already have several machines on Router 1 that are working and I want to setup Router 2 with a few other machines on the different subnet. Here is what I've configured: Connected the WAN port on Router 2 to a LAN port on Router 1 Configured Router 1 to give 192.168.1.2 to Router 2 via DHCP Configured Router 1 with a static route (192.168.2.0 mask 255.255.255.0) to 192.168.1.2 using the LAN & Wireless interface Disabled the firewall on Router 2 (since it is covered by Router 1) Configured Router 2 to "Router" mode instead of "NAT" mode Configured Router 2 with a static route (192.168.1.0 mask 255.255.255.0) to 192.168.1.1 using the WAN interface From the research I've done I think that should be enough but things aren't working exactly as expected: Router 2 can ping 192.168.1.1 and 192.168.1.101 (a machine on router 1) A machine on Router 2 can ping 192.168.1.1 and 192.168.1.101 (a machine on router 1) ping 192.168.1.1 and 192.168.1.101 (a machine on router 1) Router 1 can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2) A machine on Router 1 can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2) can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2) Router 1 and a machine on Router 1 can ping 192.168.1.2 (Router 2 itself) I'm confused as to why Router 1 cannot talk to the 192.168.2.0/255.255.255.0 subnet. Any help would be greatly appreciated.

  • Managing two domains in one virtual server [on hold]

    - by Buddhika Ariyaratne
    I have a virtual server with Windows Server 2012 on which I need to run two applications for two separate customers. Both applications run on GlassFish in port 8080. The applications run on http://localhost:8080/roseth and http://localhost:8080/ruhunu My virtual server provider has given three IP addresses. How can a I assign one address for each application. For example, if a user type www.ruhunu.org, an arbitrary URL , I want to direct to http://localhost:8080/ruhunu and www.roseth.org to http://localhost:8080/roseth.

  • How to route HyperV VMs traffic through host VPN

    - by Random
    I'm using Windows 8.1 Pro with HyperV. I have several VMs for development, all of them connected with host via Internal adapter using network addresses: 192.168.10.0/24 Where: 192.168.10.1 is my host's Hyper-V internal NIC address. When I'm not in my office I use 3G usb dongle an dialup VPN connection. I would like to route traffic from all existing and future VMs through the VPN. In best scenario traffic would be routed only partially to the local company network addresses 10.1.1.0/24 I don't want to use sharing because I'm switching between WiFi, USB 3G dongle and VPN. Moving to other virtualization is also not an option for me.

  • How to set up DHCP-configured access through a Linux box?

    - by marcusw
    I would like an old desktop box to use my laptop as a router to access the internet. Here is my setup: I have one ethernet port in the side of my laptop which I want to use to get internet access to my desktop computer. The laptop is connected to the LAN via a wireless link. Both systems run Linux. The desktop autoconfigures itself using DHCP. The laptop is a Kubuntu system. I do not have any crossover cables, though wireshark on the laptop sees the DHCP requests from the desktop just fine, so I doubt that I need one. What do I have to do to make this work?

  • F5 BigIP upgrade from 9.x to 10.x

    - by mbuk2k
    Having a few difficulties upgrading a Big IP 3400 from 9.4.8 to any version 10.x image. The following are the versions I've tried: 10.1.0.3341.0 10.2.2.763.3 10.2.3.112.0 10.2.4.577.0 To upgrade I'm running the following command: image2disk --format=volumes BIGIP-10.1.0.3341.0.iso Obviously replacing the version number with the relevant image I'm trying to upgrade to each time. The F5 reboots, and starts copying packages however after 30 seconds or so just stops copying. The cursor in the console is still flashing but no matter how long it's left, the package doesn't copy. It seems to be a different package with each version/image (but always the same package per version) at point of freezing, which I'm guessing is suggesting a space issue? I've checked free space on the device and it has over 2GB free at root which should surely be enough? If anyone has any advice or pointers, it would be kindly appreciated. Thank you

  • Difference between "traceroute" and "traceroute -U"

    - by AndiDog
    The manpage of traceroute says that the "-U" parameter (UDP probing) is the default, but I'm getting different results every time. With "-U": traceroute -U www.univ-paris1.fr traceroute to www.univ-paris1.fr (193.55.96.121), 30 hops max, 60 byte packets [...] 13 rap-vl165-te3-2-jussieu-rtr-021.noc.renater.fr (193.51.181.101) 59.445 ms 56.924 ms 56.651 ms [...] 18 * paris1web.univ-paris1.fr (193.55.96.121) 23.797 ms 23.603 ms but the normal traceroute gives me another result (never reaches the final node) - it's either "!X" or just exits after the maximum of 30 hops: traceroute www.univ-paris1.fr traceroute to www.univ-paris1.fr (193.55.96.121), 30 hops max, 60 byte packets [...] 11 te1-1-paris1-rtr-021.noc.renater.fr (193.51.189.38) 28.147 ms 28.250 ms 28.538 ms [... non-responding nodes ...] 28 site-1.03-jussieu.rap.prd.fr (195.221.126.58) 85.941 ms !X * * Note: I tried this very often and always get the same results. The path in my local network is always the same. So what does the "-U" parameter actually change here? I'm especially interested what the reason for "!X" could be (communication administratively prohibited). EDIT: If that helps, paris-traceroute gives me the following for the last hop: 14 P(1, 6) site-1.03-jussieu.rap.prd.fr (195.221.126.58) 34.938 ms !5 !T2 which means that node discards the packet with TTL=2 and returns an unknown message (not "destination unreachable" or the like).

  • How do I configure custom routes when an interface is configured?

    - by ManicDee
    Other Superuser questions have addressed the issue of adding custom routes to access e.g.: multiple networks of a corporate network through one interface, while accessing the Internet through another interface. So assuming that I have a script to add specific routes when en0 is configured, and a separate script to add specific routes when en1 is configured, is there some way I can trigger those scripts to run automatically when Mac OS X/Darwin starts and configures those interfaces? Back in my Linux days, it was possible to add an option in /etc/network/interfaces along the lines of: iface eth0 inet dhcp up /usr/local/sbin/eth0-routes-up Is there something similar for Mac OS X?
