• Why are there unknown URLs in router log?

  - by Martin

  I recently looked at my router log. Why are a lot of requests that I don't send originated from a computer in my home network? They do not look like 3rd-party advertisements / images embedded in a page. The request have patterns, such as: top-visitor.com/look.php www.dottip.com/search/result.php?aff=8755&req=nickelodeon+games www.placeca.com/search/result.php?aff=3778&req=wireless+cell+phone www.bb5a.com/search.php?username=3348&keywords=flights www.blazerbox.com/search.php?username=2341&keywords=colorado+springs+real+estate www.freeautosource.com/search.php?username=sun100&keywords=vehicle www.1sp2.com/search.php?username=20190&keywords=las+the+hotel+vegas www.loadgeo.com/search/result.php?aff=10357&req=winamp www.exalt123.com/portal.php?ref=seo2007 www.7catalogs.com/search.php?username=la24&keywords=shutter www.theloaninstitute.com/search.php?username=kevin&keywords=webcam www.grammt.com/search.php?username=2530&keywords=bob And there are hundreds of these requests send within a second. So what's happening?

• Can't ping self

  - by Paddy

  I have a wireless internet connection setup on my Mac. (v10.5.6) Am connected to the internet and everything is running smoothly. I recently discovered a quirky behaviour while setting up apache web server. When i typed in my dynamic ip (http://117.254.149.11/) in the webbrowser to visit my site pages it just timed out. In terminal i tried pinging localhost and it worked. $ ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.063 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.056 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.044 ms But if i pinged my ip it would just time out. $ ping 117.254.149.11 PING 117.254.149.11 (117.254.149.11): 56 data bytes ^C --- 117.254.149.11 ping statistics --- 10 packets transmitted, 0 packets received, 100% packet loss Pinging any other site works though. I am completely stumped. Any help would be greatly appreciated.

• Create access point (uap0) on debian 7(arm) - not found?

  - by ethrbunny

  I'm working with a fanless PC that has an ARM chipset, 2 eth plugs and a wifi card (among other things). If I install debian 6 on it all three network interfaces are available at boot time. Today I tried to install debian 7 and had numerous errors indicating that the wireless card isn't supported. uap0: error fetching interface information: Device not found SIOCSIFADDR: No such device uap0: ERROR while getting interface flags: No such device uap0: ERROR while getting interface flags: No such device No such device ERR:UAPHOSTCMD is not supported by uap0 ERR:Command sending failed! No such device ERR:UAPHOSTCMD is not supported by uap0 ERR:Command sending failed! I've tried comparing the kernel module list to the working system but there are too many other differences to make something obvious enough (to me) stand out. How would I get started debugging this problem?

• New entries on the GRUB

  - by Kiewic

  Hello. I updated my Ubuntu, and after that there were two new lines on my GRUB screen. Ubuntu 9.04, kernel 2.6.28-16-generic Ubuntu 9.04, kernel 2.6.28-16-generic (recovery mode) Ubuntu 9.04, kernel 2.6.28-11-generic Ubuntu 9.04, kernel 2.6.28-11-generic (recovey mode) Ubuntu 9.04, memtest86+ Other operating systems: Microsoft Windows XP Home Edition Do I have two kernels installed? Do the old entries are still useful? Each kernel takes up space? :P And that's not all, when a get into the old version of Ubuntu, the wireless card stops working on any Ubuntu version until I get into Windows and then go back to Ubuntu. Thanks for your help.

• Forwarding wifi traffic to wired pc

  - by brydgesk

  I'm trying to play around with Wireshark on my home network, and was wondering if there is a way to create a new connection on my PC that receives all wifi packets on the network. The PC is a wired Windows 7 machine, and I'm using DD-WRT on an Asus RT-N16 router. I'm not trying to hack anything, I have full admin access to the router itself. My searching has led me to articles about client bridges and repeater bridges, but none of them seemed to apply entirely to my situation. I'd like to continue using my standard wifi connection, but make my PC act as a repeater that receives all wifi traffic. Again, the PC has no wireless connection. I've used tcpdump which is installed on the router itself, but I'd be more comfortable analyzing the packets in Windows, as I'm trying to learn Wireshark. Thanks

• Linux Bridge, Samba netbios name/hostname access

  - by Christopher Wilson

  I am currently running a linux bridge in the following configuration ADSL Modem: 192.168.1.1 Linux Bridge: eth0: 192.168.1.2 eth1: no address Wireless Router: 192.168.0.1 My issue is that i cannot access the "Linux Bridge" shares using the WINS name of the server via client systems (yes i understand it is a transparent bridge but i can access it via the 192.168.1.2 address this is not on the same subnet as the client systems). This is the global section of my SMB.CONF [global] unix extensions = off os level = 20 netbios name = server guest account = nobody server string = 447 Server security = share #unix extensions = no #wins support = yes #wins server = 192.168.0.1 name resolve order = wins lmhosts hosts bcast interfaces bridge1 eth0 eth1 lo bind interfaces only = yes Can i access a bridged server using it's WINS name to access samba shares?

• Using URL rewrite module for http to https redirect

  - by johnnyb10

  Following ruslany's suggestion on the URL Rewrite Tips page here, I'm trying to use URL Rewrite to redirect http:// requests for my site to https://. I've written and tested the rule using a test site I set up, and so now the final piece is to create a second site (http) to redirect to my https site. (I need to use a second site because I don't want to uncheck the "Require SSL encryption" checkbox on my existing site.) I'm an IIS newbie so my question is: how do I do this? Should I create a site with the same name and host header, only it will be bound to http? Will IIS let me create a site with the same name? I don't want to screw anything up with my existing site (which is a SharePoint site, currently used by external users). That site currently has http and https bound to it. So my assumption is that, using ISS (not SharePoint), I will create a new site (http only) with the same name and host header as my existing site, and add the URL Rewrite rule to the http site. And then I guess I should remove the http binding from my existing site? Does that seem correct? Any advice, gotchas, etc., would be appreciated. Thanks.

• How to use my computer to control a lamp?

  - by nona urbiz

  I've been researching computer automation systems, but everything I've found has been overkill for what I'm interested in. Can anyone help me control a lamp that is on my desk, plugged in the wall beneath the desk, with my computer (also on the desk, usually). What got me thinking is that I have the lamp plugged into a Belkin extension cord/surge protector that came with a wireless switch that toggles the power going to 6 of the eight sockets. Can I somehow hook my computer into this? I'm not too afraid to get into some wiring type thing, but do have a somewhat limited budget. It'd also be cool to get a dimmer in the loop too. thanks aha. after more research, i have realized what i'm looking for is instructions for a DIY version of this that won't look so ugly, and that i can build a UI for rather than shortcuts.

• wireshark not seeing all packets on WiFi

  - by Caffeine Coma

  I'm using Wireshark on OSX, trying to sniff my home network over WiFi. While I can see packets that are sent to/from the host I'm sniffing on, I'm not seeing anything else that goes over the WiFi. It's like I'm not in promiscuous mode or something (the promiscuous mode box is in fact checked). The router is an Apple Airport Extreme, protected by WPA2. I'm attached to the network I'm trying to sniff, so I'm confused about why I can't see other traffic. Edit: I solved this by the following: Plug Macbook directly into the Airport Extreme router Enable "internet sharing" on Macbook, with no password. Bind wireless device (the one I wanted to sniff) to the WiFi hotspot generated by Internet sharing in step 2. Run Wireshark on the Macbook, bound to device en1. Don't forget to disable sharing after you're done. :-)

• Disabling networkmanager for a specific interface

  - by bdonlan

  I'd like to do some experimentation with hostap without disabling my primary wireless interface. How do I tell networkmanager to keep its hands off a specific interface or interfaces while allowing it to continue managing all other interfaces normally? I'm using Ubuntu 9.04. (Wasn't sure if this should go on superuser or serverfault, as networkmanager isn't much of a 'server' tool - if it belongs on serverfault please feel free to move it) Edit: I've tried adding this to /etc/network/interfaces: allow-hotplug wlan2 iface wlan2 inet static address 192.168.49.1 netmask 255.255.255.0 But this has no apparent effect, even after restarting NetworkManager. Here's my /etc/NetworkManager/nm-system-settings.conf: [main] plugins=ifupdown,keyfile [ifupdown] managed=false Edit[2]: Looks like I needed to restart nm-system-settings, then NetworkManager.

• trouble with internet connection - slow to open web pages if they open at all until I put VPN on and then they open ok

  - by Caroline Coleman

  I am having problems with my internet connection. At the moment I am on a mac and connected through a netgear wireless router. The internet connection either won't open a webpage at all or if it does it takes ages. However if I turn my VPN on the pages open at a normal speed. Also skype functions OK and I seem to be able to download files ok. I have tried connecting with a wire between the router and the computer and it makes no difference.

• LinkSys WRT54GL + AM200 in half-bridge mode - Setup guide recommendations?

  - by Peter Mounce

  I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. My ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

• Seasgate GoFlex NAS + Horrible Speed = Bad Experience

  - by Jon H

  I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up?

• How can I make a vpn network login the default behavior for logging into Windows?

  - by Danny

  To login to the machine, I have to login to our domain. When I am at work, the unauthenticated wireless permits access to the domain. However, the internet is not available until I connect via the vpn. From home, I have to connect via the vpn first, then I can login to the domain. I have successfully setup a network logon with the vpn (following the directions found here). And for the most part it works correctly. (There is an issue with logout/login I haven't figured out just yet). As I currently have to Switch User and select the Network Login button, I'd like to know if it is possible to have the network login the default behavior when logging into the system. This is mostly a usability issue than anything else.

• Why is my connection to Playstation Network so unreliable? [closed]

  - by jammus

  Hello friends. I'm 28 and my girlfriend is 24. Our home internet connection is pretty reliable, it's almost always up and can get fairly high download speeds. However, my experience with the Playstation Network is pretty frustrating. I'm always getting kicked off or getting quite high latency. Are there any tips or tricks that you might help my on-line gaming run more smoothly? I'm using a wireless connection for the PS3, is this likely to affect things?

• Prevent users from Router 2 seeing Router 1 computers

  - by Patrick Robert Shea O'Connor

  I've got 2 Netgear N300 (WNR2000v3) routers. Here's my setup: Modem Router 1 Private Users/Router 2 Public Wireless Users on "Guest" Network. I want to prevent users who are connected to Router 2's "Guest" network from accessing anything that is connected to Router 1. There is an option when setting up the "Guest" network called "Allow guest to access My Local Network" which I thought if unchecked would do this very thing; however, I can still access files and such of computers connected to Router 1. Router 1 assigns 192.0.0.x IP addresses, Router 2 assigns 10.0.0.x IP addresses, how can they even see each other? Do I need to change the subnet or something else?

• Accessing Windows from Linux/Mac by name using TCP/IP

  - by stevekuo

  What are some solutions to access Windows by its computer name from Linux and Mac using TCP/IP. That is, from terminal I want to be able to ping my Windows PCs using its host name. My setup is: Various machines running Ubuntu, Windows XP and OS X. Networked using a consumer grade wireless router which provides DHCP. The only DNS is the ISP's, which resolves Internet names and not local host names. The Windows machines can ping each other by name. The Ubuntu and OS X machines can only ping Windows by IP address (name doesn't work).

• Replacing DropBox with: Amazon S3 + SSL + GPG/TrueCrypt + Mounting on OSX ??

  - by Matt Rogish

  So, right now we're using DropBox to share various data files around between approximately 10 Mac OS X systems. However, we already have an S3 account and everyone on the lowest DropBox plan of $10/mo seems too expensive. So, I am contemplating something that would allow us to replace DropBox with our own home-grown solution. We are all fairly technical people and/or smart enough to follow some steps, so if it's not as "user friendly" as DropBox we're all comfortable with that. There are plenty of docs out there that have bits and pieces of what I want but some of the tools don't seem to fit the requirements: Transport security via SSL to the bucket Encryption of bucket contents Bi-directional syncing Most of the scripts I can find on the internet use "duplicity" which appears to fail #1 (it doesn't look like duplicity supports SSL to S3 - the docs don't state but the protocol looks plain old http http://www.nongnu.org/duplicity/duplicity.1.html#sect6 ) Many scripts use gpg to encrypt files. This seems like it could work, however I have to make sure that each OSX client is able to use the same key to encrypt and decrypt files (key management is left to me to manage). Finally, most of the scripts use one-way replication, e.g. using Amazon S3 as a simple backup store. As we'd be using Amazon S3 as the "repository" they fail this one. Whew. So, I'd love a single tool that does this but after an exhaustive search I don't think one exists. I'd be happy just knowing which tools out there can fulfill my 3 requirements, after that I can stitch together the rest. Any thoughts? THANKS!

• What is the type/classification/term for an PC headset that does not go over the head or back of the

  - by FMFF

  How do I search in the leading auction site for the PC headset(earpiece + microphone) that does not have a band to go around or over your head - instead it is entirely like a cable, with the microphone attached in one of the wires leading from the ear piece? How is it called? I'm not talking about Bluetooth wireless headsets. I have one from Plantronics I got years ago, which they stopped making and I want another one, but don't know how to search. Simply searching for HeadSet or similar terms, brings mostly the newer ones which I don't want. Thank you.

• Torrent upload ratio not updated on Synology DS212+

  - by user179271

  I have a Synology DS212+ NAS running DSM 4.2-3211 (current version). I use it for several purposes including torrent download using Download Station and a tracker that needs authentication. My problem is that my download/upload ratio isn't updated, so it constantly falls down. My NAS is behind a router, and I configured the NAT to forward ports 6890 to 6999 to the internal IP address of the NAS. Here are the Download Station settings : TCP port : 6990, Sharing ratio : 900%, Sharing time : infinite, max download speed : 0 (no limit), max upload speed : 0 (no limit), BT protocol encryption : checked, max numbers of peers allowed by torrent file : 4000, DHT : checked, with port 6889. When the DHT option is not checked, the NAS doesn't upload any files. I don't know what is this option for. Can someone help me to solve this problem ? Did I miss any step, or does it come from the NAT ? How is the authentication managed by Dowload Station ? (Sorry for my english) Thanks.

• How to set up simple VPN for secure Internet connections over unencrypted Wi-Fi on Windows?

  - by Senseful

  I'm looking for a solution similar to the one in this question, except that I don't have a linux computer. I have windows computers that could be set up to accept VPN connections. Preferably I want to set this up on either Windows Server 2003 or Windows XP. I'd like to connect different devices (e.g. iPhone, iPad, laptops, etc.) that are on open unsecure wireless networks (e.g. the one's you see at places like Starbucks) to this VPN to ensure that all my data is secure. I found an article that shows that you can enable VPN connections on Windows XP. After following those steps, though, I'm not sure what to do. Which ports do I open on my firewall? Which VPN settings do I use on my devices such as the iPhone? Do I use L2TP, PPTP, or IPSec? What's the difference between these? Are there any other steps missing in that tutorial? I'm hoping that since Windows has this built in feature, that it will be much simpler to set up rather than having to deal with setting up something such as OpenVPN. If I follow those settings and enable port forwarding on port 1723, and then use the following settings on the iPhone: PPTP (IP Address) RSA SecurID: Off Encryption Level: Auto Send All Traffic: On Proxy: Off It shows "Connecting..." then "Disconnecting..." and the following error message: VPN Configuration A connection could not be established to the PPP server. Try reconnecting. If the problem continues, verify your settings and contact your Administrator. I'm using a user account that I enabled privileges to in the VPN settings on the Windows machine.
