• How to put fear of God (law) into Wi-Fi hacking neighbors [closed]

  - by Shakehar

  I live in an apartment and some new guys have apparently moved into one of the apartments. They have been shamelessly hacking into my WiFi. Mine was initially a WEP encrypted network and out of laziness I just limited and reserved the IPS on my router for the people in my house. Yesterday I had to free up an IP for a guest in my house but before he could join the network these guys connected in. I have changed my encryption to WPA2 and hope they dont have the hardware/patience required to hack into it, but there are many wi-fi networks in my apartment most of which are secured using WEP. I don't really want to call the police on them. Is there any way to deter them from misusing other people's wi-fi ? I have gone through I think someone else has access to my wireless network. What next? but I have already taken the steps mentioned there.

• Windows 7/8 can't connect to an N Router

  - by xenoterracide

  I have a router running OpenWRT backfire, with N and A/B/G being broadcast. A linux laptop, and a Mac laptop can see the N network and connect to it (or at least they could last weekend). But there is now a Windows 7 Desktop with a B/G/N wireless card, and a Windows 8 Laptop with a B/G/N wireless card that can't see the N network only the B/G broadcast. The B/G and N have different SSID's and Encryption ( WEP and WPA2 PSK respectively ). The N SSID isn't even visible. Does anyone have any suggestions as to how to troubleshoot further? Or what might be the cause? update wireless info Desktop Dell Wireless 1502 802.11b/g/n Atheros Communications Inc 9.2.0.412

• Vlan Tagging at Access Port in Switch

  - by singh

  I'm Confused from the fact that Vlan tagging is done at access port and trunk port always gets tagged packets (until its case of native vlan).But I still believe in other fact which says tagging happen only when a frame hit the trunk port which means trunk port gets untagged frame and tagging is not possible at access port. Would like to know where actually this tagging happens ? and also which command we can use to encapsulate 802.1q protocol to access port ? The way we do at trunk port is switchport trunk encapsulation dot1q Is the above command applicable for access mode also?

• VM connected to network but not to internet in VMware Player 6 on Windows 8.1 host

  - by user1257262

  So I am running Bitnami's MEAN stack in VMware Player 6.0.2 on Windows 8.1 and the VM connects just fine to the network: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG However, I am having a great deal of trouble getting the VM to communicate with the internet. No matter what sort of action I take (even something as simple as apt-get update), the machine just sits there and eventually fails to connect. Here is my VM's Network Adapter configuration: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG On my host Windows 8.1 computer, I actually have the VMware Bridge Protocol enabled but for VMware Network Adapters (VMnet1 and VMnet 8), but they are listed as having No Internet access in my Network and Sharing Center. I am not entirely sure if these adapters are relevant to connecting the VM to the internet, to be honest. This is the first time I have ever had an issue connecting a virtual machine to the internet. This problem is also happening with other VM's I am trying to run. Can someone tell me what I am doing wrong and how I can fix it?

• Remote reboot of windows to knoppix

  - by user64452

  I am attempting to develop an Auditing application. This audit application will be employed on windows networks. The Audit will need to discover Hardware and software details of all machines attached to the network (including Printers) I do not want to have to install this application on each workstation. The audit app. needs to discover all the ip addresses of all the networked workstations. I have been prototyping this app for the last couple of months and have decided to try a new tack Is this possible? a). You have a windows network, min Windows XP sp3 and upwards b). Maximum of 100 Networked machines (if that matters) c). I need to remotely reboot each WINDOWS machine in turn on the entire network and get it to startup using UNIX, say knoppix for example! d). however the knoppix live cd is only available from one of the networked machines Questions... Morphology? Longevity? Incept dates? Cheers DD

• Network Bridging on Linux for OpenVPN

  - by Coyote

  I've been following all the OpenVPN Bridge tutorials I can, but I'm still missing something. Does anyone know of a super detailed tutorial\explanation of bridging? If anyone has bridging running, can I get a copy of your interfaces file to see how you've got it going. (Obviously change the ip address, just please change them consistently.)

  - by Fr0zen1

  I know you are going to say that this has been answered already, but it hasnt. None of those solutions worked 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?

• 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?

• Real time audio streaming

  - by Josh K

  I have a remote computer running OS X. I would like to stream the audio from the microphone input over the network so I can listen to it. Primarily I want to do this because I'm out of the office but still need to communicate with people there. I would like to use VLC, but am not fully aware of the options available. I tried SoundFly (as recommended by another answer) but this didn't seem to want to connect. At this point I should note that I'm using a VPN network to connect to the remote computer (using Hamachi). I can open up ports / etc fine though, so I should be able to do this. Alright, I found Nicecase which does exactly what I want but I would prefer to not have to shell out $40 for it.

• WLAN adapter on Ubuntu Server inside Hyper-V

  - by Firefox333

  I need to set up an Ubuntu server as a router. However we need to make it wireless and wired. I need a WLAN adapter for the wireless part of the router. I get my Internet connection on my server through my wireless adapter from my host but it automatically sees it as an Ethernet adapter instead of as a wireless adapter. Is there any way of making a (virtual) wireless adapter on Ubuntu server 12.04 inside a hyper-v machine?

• Lan DNS not working after reinstall of Ubuntu 13.10

  - by DrorCohen

  I upgrade my Ubuntu desktop to 13.10. When I say upgrade I mean installed on a new partition from scratch (old partition is available if To the problem: I'm trying to ping a host (Drobo-FS server) by it's host name. I get "Unknown Host". However pinging from another computer on the same lan - works fine (a laptop with 12.04 lts). for that matter every ping from the 13.10 to the local lan by hostname fails, ping with ip works. I don't have a local DNS server but somehow all the other computers in the network find each other by host name - only this new one fails... help appreciated...

• syslog log of TCP packet

  - by com

  Occasionally, I noticed a lot of following messsages in syslog Nov {datetime} hostname kernel: [8226528.586232] AIF:PRIV TCP packet: IN=eth0 OUT= MAC={mac} SRC={sourceip} DST={destinationip} LEN=60 TOS=0x00 PREC=0x00 TTL=63 ID=20361 DF PROTO=TCP SPT=39950 DPT=37 WINDOW=14600 RES=0x00 SYN URGP=0 On the Internet, I found that DOS attack may cause such type of output, unfortunately, I don't understand what does this log mean. The only thing is clear for me is this log is related to network. The source host is the host where nagios is installed. Does it mean nagios somehow does behave well? And what does it mean at all?

• Outbound ports to allow through firewall - core requirements

  - by dunxd

  This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support email and web access, which I know everyone will need: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working? I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

• Blacklist a single access point of a wireless network

  - by Zr40

  At my university, one of the wireless access points is failing. When something tries to associate to the network using that access point, it deassociates the client, claiming 802.1X authentication failure. Other access points do work normally using the same credentials. The issue has been reported, but after a month it still has still not been fixed. Now, I'm looking for a way to blacklist the access point's BSSID, so the OS prefers other access points on the same SSID. How can I blacklist specific BSSIDs in either Mac OS X Snow Leopard or Windows 7?

• Connect a Sitecom WL-174 to another wireless router

  - by Thijs Wouters

  I used to connect via a Sitecom WL-174 directly to ADSL internet. There were some pc's which connected wirelessly and some connected with a wire. Now we got another provider and we need to use the router which came with it. It is also a wireless router. It works perfectly. But I need to connect the other pc's which were connected with a wire previously. Is it possible to connect the Sitecom router wirelessly to the other router? If so, how? Thanks.

• Why is a network ID not needed to connect to an IP address?

  - by baddogai

  I know how IP basically works, and knows that an IP address composed of a network ID portion and a host ID portion, but when I type a IP address, say 8.8.8.8 into the web browser, I didn't supply any subnet mask information. So, how does the browser know where the dividing line is between the network ID and host ID? Since 8.8.8.8 may mean 8.8.8.8/8, 8.8.8.8/24 etc. In a nutshell, the IP address I supplied is ambiguous.

• Forward public port to localhost

  - by Dan

  I have a process running on my Ubuntu 12.04 server that insists on binding to a public IP address. I only want it accessible from localhost, and NOT the outside world. I've been trying to work out a way to forward 1.2.3.4:8888 to 127.0.0.1:8888. I saw something about iptables not wanting to forward connections to loopback, and I haven't been able to make it work with xinetd either. It's also important that the connection not only be available on localhost, but be inaccessible on the interface it's trying to run on. Is this even possible?

• How to connect to internet 2 or more pcs with an usb wifi adapter

  - by bhaoahd

  In one pc I have an USB Wifi adapter (Realtek RTL8187L Chipset), from there a 10 meters cable to an outdoor antenna. With that I connect to a public Access Point. Now I want to be able to connect more computers to internet using that same connection that comes from the outdoor antenna, what options do I have to do this? I do have another usb wifi adapter with a small omni antenna, and a router encore ENHWI-G/A. This router can be used as a Wifi AP, but it needs a modem that works with the RJ45 connector. Is there a way I could take internet from the outdoor antenna, and create another AP indoor using that router to "repeat" that wifi that comes from the outdoor antenna? If creating this second AP is not possible, should I use some sort of local network between computers, connect my main PC with the outdoor antenna, and share the connection through the lan? (I would really prefer to have a second AP indoor so I can connect other devices like a Palm, but I am not sure how could this be possible with this router and the usb wifi adapter)

• Uploading to YouTube makes all browser tabs and devices disconnect

  - by fabsenet

  Whenever I upload a video to YouTube all other browser tabs behave like there is no connection at all. It even affects my phone and other computers on the network therefor I think it has to do with my router. When the upload is done everything works normally again. I never observed this behavior with any other upload. My router is a Fritz!Box 7390 and my uploading PC is connected through a 1000mb/s switch (wired) to the router. Uploading through another browser does not change anything. I understand that other sites become slow as the network resources are limited, but stopping altogether feels wrong. speed.io measures for my internet connection: 40.894 Kbit/s down, 2.685 Kbit/s up, 29 ms ping, 2.048 con/m connects

• Sharing a printer on Windows home network
