Your modem is just a modem. And if you set your router to AP mode, then it's just an access point. That means you have no router. Without a router, you can't have more than one device using your Internet connection. That explains why your phones don't work. If you want help troubleshooting the configuration that should work, you'll have to tell us what goes ...

It may be because, your router has a channel number which your system doesn't support. I also had the same problem. To solve this, you have to go to router settings and edit it's channel number. Most probably it might be selecting automatically. You set that to a lower value. Eg 1 or 3

Without knowing what specific network card you have in the system, this is the best I can provide: http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-8200/drivers Also, this system doesn't use a 64-bit processor, nor does it support the RAM requirements of at least 4GB for any 64-bit Windows Operating System. So no, it would not ...

I suppose you mean Cat5.. the cable. Rather than the ethernet protocol. If you wanted ethernet the protocol then maybe you'd want some kind of ethernet over IP with KVM Extenders. I haven't really tried that.. So, ethernet aside. Yeah.. Any KVM Extender. Or if you google for VGA over Cat5 then you'll see that specifically for VGA. e.g. I see a company ...

So, are any ideas how to force Windows 7 computer to share Internet both wirelessly and via wire? I would not suggest you using Windows 7 as a software router. The ICS is a limited NAT component. Windows 7 doesn't support acting as a software router by default. You need some routing software to achieve your goal. Besides, any Linux distribution can easily ...

Do I need to configure service C to bind on x.x.x.2 only? The simple answer is Yes. Normally, the OS doesn't determine the address used by services. OS just give the choice to application. If a service bind to 0.0.0.0, it means that the service listen on any available address on the OS.

Actually, this issue is not related to Azure. The root cause if this issue is that the default gateway has been changed when we establish a VPN connection. Please follow the steps below to resolve your issue: Configure your VPN client to don't use VPN server as default gateway. Add some static route entries to make sure that the client is able to access ...

Getting a better router/access point setup will help your speed if the issue is with your LAN (and from what you describe it is), but it will not allow you go faster then 3mbps (ie about 300kbyte per second). Range extenders are generally a bad idea as they greatly reduce the available bandwidth. The "correct" solution is to cable multiple access points ...

In VirtualBox, the network connection is by default set to NAT. This means that there's a virtual router in place that allows internet traffic to go through, but blocks everything else, unless you open the specific ports. There are a few routes you can take here. Either open the ports or change the network to a bridged network type. The problem with the ...

I am using a TP-Link TL-R480T+ Broadband router with load balance. I use it to split up different computers and services on the two existing internet connections, which clearly eases the load. What does not work, is to combine the two connections to one, if you use a "point-to-point" connection, like loading web pages or accessing FTP. On the other hand you ...

What guest OS's do you use? I use Windows 10 and my guest OS's are connected. In your guest settings (Virtualbox), go to network adapter, and set the attachment to NAT. If your guests are Windows 7 or later, then set the adapter type to "Intel PRO/1000 MT Desktop" and check "cable connected". My XP 32-bit guest's adapter type is set to PCnet-Fast III.

Here's an extremely simple way of looking at it, that those new to Subnetting found it very easy to follow. So you're given your networks, and are told to break them up into smaller networks. Lets says that we have the 172.18.0.0 /16 network, and we want to break it up into smaller networks. To do that, we need to borrow some host bits from our given ...

Continued from: http://serverfault.com/questions/49765/how-does-subnetting-work/49836#49836 Your ISP gives you the range the network ID 192.168.40.0/24 (11000000.10101000.00101000.00000000). You know that you'd like to use a firewall / router device to limit communication between different parts of your network (servers, client computers, network equipment) ...

IP subnets exist to allow routers to choose appropriate destinations for packets. You can use IP subnets to break up larger networks for logical reasons (firewalling, etc), or physical need (smaller broadcast domains, etc). Simply put, though, IP routers use your IP subnets to make routing decisions. Understand how those decisions work, and you can ...

It's because the predefined "CSV" format always includes the Node column. See the XSL transform file here: %WINDIR%\System32\wbem\en-US\csv.xsl It's been that way since XP days. Why MS decided to do that, I'm not sure.

Whether you use robocopy of Windows Explorer doesn't matter. The computer you run the command on always acts as middle-man in the transfer and all traffic passes through that computer. So yes: It would be much more efficient to push the files from the remote server to the remote clients. That way all traffic stays on the remote site.

if you want dnsmasq to serve IP addresses from the same subnet to different interfaces you can edit the interfaces declaration in the dnsmasq.conf look under interfaces in the man page here.

This sounds like a problem with reverse path filtering. Edit (as sudo) the file /etc/sysctl.conf on the Debian machine, make sure to have the two lines as follows: net.ipv4.conf.default.rp_filter=0 net.ipv4.conf.all.rp_filter=0 save, reboot the machine, see whether you still have the problems in question. If not, then the easiest way to solve would be to ...

POE can be anything up to 48 volts. While there are some standards (802.3af), there are many systems which run lower voltages - 12 volts is common. 802.3af can push out about 15 watts - which is quite a lot. Generally the higher the voltage the higher the amount of watts which can be pushed through a cable. (802.3at - which I know little about can push ...

POE treats each pair as a single conductor, and can use either the two data pairs or the two spare pairs to carry electrical current. Power over Ethernet is injected onto the cable at a voltage between 44 and 57 volts DC, and typically 48 volts is used.

Turns out there was some bad routing going on from my ISP to the server that was apparently resulting in the connection being capped at 100kb/s. The datacenter was aware of an issue with the traffic from my ISP and suggested that I get rerouted. I switched my local machine's public IP to a different subnet which ultimately got me a different path to the ...

Teamviewer isn't supported on ARM processors. I've seen that there's an x86 emulation I believe called exagear that can do that and get Teamviewer on the pi... although that seems like the long way around to solve the problem. I would solve it this way.... Setup an openvpn server out in the wild. Make it a port that no one in their right mind would ...

Some "datacenters" offer the gigabit connection shared between several servers. Thus when others transfer a lot of data, your connection speed will decrease. First verify your plan details - that you indeed have guaranteed 1 gigabit speed at all times. DDoS cannot be ruled out - but datacenters generally can identify and block this kind of traffic - so they ...

Just get your ISP to forward the port to a static or reserved IP in your LAN and make sure your camera has that IP - a static or reserved address will always be given to the same device. It will be much simpler than trying to find a much more complicated method that your device probably doesn't support or will mean you installing additional hardware (...

If you ISP supports IPv6 then you might be able to connect your phone to an IPv6 broker and therefor bypass the router. If they don't then you are left with VPN option, then again you can go two ways. Setup up a VPN server at home and have you ISP do the port forwarding to allow you to connect the phone to VPN. (This is only good if your ISP provides ...

The amount of power contained in PoE is the amount of power injected by the PoE power supply. A quick look at the manual for your device shows that it comes with a "power injector" which is how the voltage from your AP's own power supply gets into the Ethernet cable. Another way to understand, in the case of slower Ethernet (under gigabit speeds), cables ...

Electric voltages can be adapted, reduced and increased. That's how the 12V DC adapter turns 230V AC or 110V AC into 12V DC. Similarly, this is how PoE-compatible devices (like your AP) will reduce the 37~57V of PoE to 12V, 5V or 3.3V, depending on the voltages they need for their internal components (some ICs can't bear voltages above 1.8V, yet you feed ...

Problem (sort of) solved! Thanks to @grawity I investigated the output of traceroute6 and found out that the IPv6 I used did not work.

According to http://www.manualslib.com/manual/864771/D-Link-Dir-803.html?page=102 the router has the ability to send the syslog to an external device that is running a syslog utility that can be used to store every request into a file or database - allowing you to keep much more of the logs. Syslog is real-time so you'll want the "database" server to be on ...

how do I filter SSL traffic without throwing errors in client browser without fiddling with students devices? Fortunately you cannot! Because if you could, anyone could and there would be no internet as we know it. Would it help to have real certificate from trusted CA not to throw any errors? No, it would not, because DigiCert would sign a ...

Using certificates would require you to create at least one certificate per website accesed by your users (certificates contain the domain name). DigiCert seems to be installed (in Windows at least) as a trusted root CA so that could work, and would need verification on non-windows computers. However, I would recommend that you re-evaluate what has been ...

Its difficult to say why its failing without seeing a full output of the rules, but my guess is that this rule is being inserted after a more permissive rule allowing it. Note that you have used "-A" which appends the rule to the end of the table. If you use "-I" instead it will prepend it which is probably what you want.

Normally, the source ports are randomly generated unless you have specifically defined. So a better way to block certain port at destination side. You can reference to the answer Rakesh Pant suggested.

Ping would be enough if it is really just about outages. You can use gping which provides a graphical result of the measures. A ping won't affect the traffic. As for alternatives, the question you linked in the first place has already some very good ones like mtr or MRTG.

Any part of a server can be made redundant, but there can be significant tradeoffs which might be deal-breakers - depending on what you are doing - The biggest one in many cases is redundant sites - even if you have 2 PC's if they are situated far from each other, latency can play havock with your IO.

By default the Guest runs using a NAT network, meaning that it is secured to not let anything get out unless you make it possible. A virus can always come in the Guest, but it will then be contained inside the guest.

You'll need to first disable the Sharing settings under System Preferences -> Sharing and turn them off on the left by unchecking them which will automatically remove them from the Firewall allowed list.

To scan the status of a range of IP addresses, this is nice and simple: sudo nmap -sn 192.168.1.2-20 Where: -sn: Ping Scan - disable port scan Note: In previous releases of Nmap, -sn was known as -sP.. I did this on Mac OS X (which is based on BSD). I am not sure if the Linux version has any differences.
