I'm trying to create a simple WPA2 WiFi access point so that I can use WiFi more reliably when I'm far away from the router. I'm following this guide except I'm using a custom version of hostapd that has the driver for my USB WiFi dongle. I modify the hostapd.conf configuration slightly from the guide to create an open hotspot: interface=wlan0 ssid=WiFi chael=6 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 driver=rtl871xdrv ieee80211n=1 hw_mode=g device_name=RTL8192CU manufacturer=Realtek When I do this, everything works like a charm and I can browse the Inteet when coected to the AP from my phone. But, of course, an open AP is not desirable and I wish to create a WPA2 AP so I modify the...

I´ve purchased a new monitor with 144Hz refresh rate. My old monitor support 60Hz. It got me thinking: How does vsync for a window work when it cover both screens? Do developers (like myself) have to make any special considerations for this to avoid performance drops or tearing? This question makes the assumption that vsync sync towards the slower monitor. This is at best plausible when the refresh rates has a decent common divider, such as 60Hz for a 60Hz and 120Hz screen. However if I set my screens´ refreshrates to 60Hz and 144Hz the common divider is 6Hz, ie not very impressive. Indeed, my faster monitor could be set to 59Hz, making the common divider 1Hz. If the sync however really is f...

So I have a Telsec TS-9000 modem, and I'm testing an old computer, using Windows XP SP3, firewall disabled, antivirus disabled, not behind a router, the modem's DMZ is disabled, I forward the port 8080, tried other ports too, but whenever I test them on online PING services, like this one ttp://ping.eu/port-chk/, it tells me the ports are closed. Have already restarted the modem. And the IP being used for opening ports is 192.168.1.3, any other than that, my IP is dynamic, I don't know how to say that, perhaps one it's local IP and the other one is my ISP IP. I really need to open those ports. Also, when I go to firewall settings and hit the option Filter IP/Port, the first two options Outpu...

I am fairly green to the networking game but I will try to explain the best I can. I am using a Raspberry Pi 3. I have dnsmasq and hostapd to create a wireless access point. I was successful in doing so as well as port forwarding the inteet from ETH0. However, directions have changed. What I want to accomplish is to continue utilizing my RPI as a wireless access point yet without inteet access. What I would like to achieve is to have a wireless access point that hands out IPs (dhcp server) as well as an Etheet (access point?) static network that hands out IPs (dhcp server) if requested. I would like to have a setup like... rpi_eth0->static IP = 192.168.1.3 rpi_wlan0-> static IP = 196.168.1.4...

I have devised Audit workbooks with up to 21 pages with Yes/No tick boxes for each question. I have linked each tick box with the Yes/No cell for each question (very time consuming) but I need to now have a final score on the last page to add up all Yes (True) answers so i can then do another formula to calculate the percentage. I have not really got room to add another column on each page as space is limited. I was hoping there is a formula i can use at the end to cover from Page 1 to end?

I've recently installed Metasploitable 2 and I would like to set up it's network in the following way:I'm ruing Metasploitable 2 on a VirtualBox on my PC, and what I'd like to do is to be able to communicate with it through Kali Linux which is installed on my laptop (not virtually).

Let's say I am working on an .html (or any text-based) file in vim. Next, I need to open a new pane to work on the terminal. How can I achieve that?

I installed CentOS 7 on a virtualbox machine.When I set the network to NAT, ping gets packets back, wget gets pages and yum also works.However, if I shutdown the machine and set the network to Bridge, ping gets packets back but wget and yum hang. I have the below set up in /etc/sysconfig/nework-scripts/ifcfg-enp03 (but this file is not changed at all. Only the virtualbox setting for network is changed) TYPE=Etheet BOOTPROTO=dhcp NM_CONTROLLED=yes ONBOOT=yes NAME=enp0s3 DEVICE=enp0s3 ... Let's block ads! بخوانید...

Here's the challenge: I will be installing 10 TV screens into 10 different locations in my city. These are WiFi-enabled smart TV's that can be controlled via a software called MDC (Multi Display Control). MDC can only coect to screens that are on the same LAN. The problem is that I need to control all of them from a remote location. I will be able to use the locations WiFi, but will not have access to their router settings. What I've come up with: I'm not a network engineer, but I have been around computers for a while. This is my potential solution... I believe that I will need to create a VPN. The "smart TV's" can coect via WiFi or Etheet and have basic network settings (IP, Subnet Mask, R...

I'm still trying to get a remote access to the MS SQL Server on one of my Windows machine. I allowed the access on my Windows firewall as can be seen here and here. I also opened the port on CoMoDo FW as can be seen here. But trying to access the machine from the Linux with busybox telnet 192.168.1.4 1433 does not produce "Coected". The server itself does configured to accept the remote coections. What other settings I'm missing? Thank you. Let's block ads! بخوانید...

Back when I had Windows 8, I would run Hosted Networks from my computer all the time using the netsh wlan start hostednetwork code in the command line terminal. However, since I have updated to Windows 10, I have been unable to start a hosted network. I have looked all over for an answer and there is nothing. When I type netsh wlan show drivers the command line comes up with Hosted Network Supported : No but, it use to work, it use to be supported. In my research for trying to find out why this is, I have found many tutorials on saying to Enable the "Virtual Network Adapter" within the Device Manager with Hidden Devices shown, however that device does not appear. I have tried to scour the in...

I have a very strange behavior that I would like to understand on my home network. Sometimes I lost coection to outside (request timeout on ping 8.8.8.8 for few minutes) but I don't loose coection on already made link. For example I can have a google hangout call that will not drop but during this call I will see request timeout on 8.8.8.8 for few minutes. When I do an mrt and the coection drop. It drops on nearly all points. Coection seems to drop right after the router at home.

I've a little problem with my new virtualization setup. On my host machine (Windows 10 Pro) I just installed the current Version of Microsofts Hyper-V (via "Add Windows features"). My host Computer have two network cards.

I am having a problem with my HP Pavilion computer. Every time I type something, and start to use the shortcut Ctrl+Left Arrow key, it doesn't respond. The keyboard works perfectly fine overall, including other shortcuts but not this one. My laptop is an HP Pavilion x360 computer with Windows 10. It works after a while, but then when it goes to sleep or about to go to sleep mode, or at a small period of time--to which I don't know how long--it stops working. Sometimes it does not work without sleep mode. Please I really need your help. I have tried to contact HP support for it, but they suck. I keep being sent to tech-supports from outside the state who can't speak good English and caot unde...

I'm trying to sync the clocks on a Windows 7 (A) and a Windows 8.1 (B) computer on their own, private network by using the command (cmd on computerA): net time \computerB /set /y As I expect, this command gives me an access denied error, since the local administrator account on computerA doesn't have permission to computerB. I would like to set up an account, or allow Everyone or Guest permission on a specific area of computerB, so that this time sync can occur properly. Unfortunately, I can't seem to find any documentation about permissions related to this command, and because of that, I'm working under the assumption that this command will require administrative privileges on both machines...
