I know who chose these address ranges. Unfortunately, he is dead, so I cannot ask him exactly why he chose them, but I can make some well informed guesses. There isn't much online dating prior to the mid-1990s, when the Internet really started to take off. What history of the Internet exists is mostly in the RFCs which define it, which date back to 1969, at ...

your subnet and your range are in different networks. the range definition must be in the same network the subnet defines. Also, set your subnet address to .0, not 1. .1 is a host, .0 is a network. finally, every option must end with a semicolon (;) ... subnet 192.168.56.0 netmask 255.255.255.0 { range dynamic bootp 192.168.56.25 192.168.56.200; ...

When it "fails", you can see you get an SOA record from a real root server so that means your name server went out the usual path and tried to find the answer out on the Internet. The reason for that is your forwarder (172.21.2.1) didn't respond quick enough so it fell back to finding the answer the normal way. To stop this, you need to add forward only to ...

A better approach to this (and the method Microsoft recommends you do) is not expose a RDP port to the outside at all. Instead expose a VPN port that the user can connect to, then once on the VPN connection they can connect to the RDP server. This will allow you to restrict which users have VPN access separate from which users have RDP access. If you don't ...

See the answers posted here. "In your case both source and destination IP address are in the same subnet, so the destination is directly reachable and the packet is thus delivered directly without router involvement. That's why you see only a single hop in the traceroute output."

There are a number of open-source network simulators that meet your requirements. They all create and connect virtual machines to form a virtual network running on a host PC. Students can run open-source networking software, such as quagga, on each VM and use other open-source tools, such as Wireshark, to monitor activity in the virtual network. Some ...

This is a little late, but may help others search around. OneDrive does not want any part of a network drive, but you can trick it into using a mapped network drive as its primary storage by creating a Symbolic link. Here's the quick and dirty steps: Create folder on the root of your C drive (e.g. C:\Share) Create a folder inside of that called ...

This is caused by a bug of IE9. If you stop the proxy service it will return a RST packet and IE9 will add the proxy to the bad proxy list. If your proxy server is actually down and there will be a TCP timeout IE9 will not put your proxy to the bad proxy list. In order to solve this bug, you have to install following hotfix: ...

I had a shell script for doing something like that a long-long time ago but, sorry, could find it. So I can only give you the pointers to the solutions I implemented back then. I'm writting mostly from memory so some examples are missing: I had one routing table per uplink (ip route ... table 101, ip route ... table 102). That goes into ...

Take a backup of your documents and personal stuff, format the harddrive and reinstall Windows 7. That is the easiest and safest solution.

I got the same problem yesterday on a Galaxy Note 3 with Chrome. Clearing the app data helped for me. More details: Every website I went to redirected to this url with an error system-check-elotpdux.in/js?t=sjdhehdjsjdi (long string) The page says "not found" Before the redirect there's actually another one to an IP: 94.249.192.105/index.html I ...

Yes, we had the problem in Italy on the last days: primary DNS server on router/modem modified to 94.249.192.105 -> ransomware (javascript) downloaded from this same server by any device on the LAN and multiple sites and services blocked. See also ...

Why not just open Control Panel - All Control Panel Items, right click on the link for Network and Sharing Center, choose Create Shortcut, that'll put a shortcut on your desktop, you can rename the shortcut to whatever you like - then move it to your system root folder and voila! open it from the Run command or copy to a flash drive for portability.

It's not possible to do it in 100%, but there's a hackway for doing it partially. This trick changes some registry keys to achieve it. It helped me to change computer name in network (remember to run it as admin and restart network adapters after it). It also changed the computer name in System Properties window and in some other places. If you change ...

The largest LAN that I know of belongs to San Diego City Schools. All internet traffic is funneled through a gateway that prohibits the students from accessing sites with mature content (and a bunch of other sites as well). From their gateway, the information goes to each of the schools in the district (by fiber I believe). As you can see from the map, the ...

If you copy the linux virtual machine (in this case is BackTrack 5 R 3 vmware version) from an external disk or from a directory to a new directory in your computer then run it at first time, there is a notification to “I Copied it” or “I Move it” . Usually if you choose “I Move it” and after entering the desktop by startx, then you’re trying to ifconfig ...

You can't use wildcards in /etc/hosts. There no way to do this without DNS server. You have two options: 1) Put every custom host that you need in /etc/hosts (you could automate it with a custom shell script) 2) Simply use a custom local DNS for this task. I would recommend dnsmasq. You just have to use --address=/local/127.0.0.1 parameter in dnsmasq, ...

The best I can offer you is something that may still only get you halfway there: On your host machine (your own computer) you'll want to be on the same network as this device (10.0.1.2 through 10.0.1.254 will be safe bets). My assumption is that this is already configured for you and the dhcp server is giving out addresses in that pool. Once all of that is ...

Just "two cents" more: e.g. mtr -nrwc1p --timeout 5 www.google.com is a nice replacement for traceroute (Hmm... don't know it if is available for windows) mtr --help or man mtr for more info.

will wireless devices such as laptops and phones roam freely from one network to the other? Yes, your device (laptop, phone or any wi-fi equipped device) will search for SSID's that you saved. If one is found (wether its from Jane Doe or John Doe), it attempts to connect. Once either networks has some security measures like MAC-filtering, you will get into ...

Wi-Fi clients can't tell, before they connect, what wired network a given AP will connect them to. So if you have two APs publishing the same SSID with the same security type and password (or no security at all), clients will roam to it thinking it's part of the same underlying network. If the two APs actually connect to two different underlying IP ...

Ethernet switches do not broadcast all traffic to all ports. A unicast exchange between two hosts on two separate switch ports will not be seen by a listening host on a third switch port under normal operating conditions. More expensive managed switches, with enterprise functions such as VLAN support often have port mirroring features, that serve as a ...

Looks like dnsmasq is starting correctly. You should test if dnsmasq is correctly working with nslookup test.local 127.0.0.1. To make sure the system is using dnsmasq, you have to update the /etc/resolv.conf to use nameserver 127.0.0.1 as first option. You can also use a custo upstream resolver configuration on dnsmasq with ...

I assume that your intranet is connected to the Internet? If so, it's probably behind a NAT router, which would mean that the IP allocation inside the network is different from outside. This is a commons network security measure. More info on HowStuffWorks: Network Address Translation allows a single device, such as a router, to act as an agent between ...

The manual for your Sitecom router appears to have instructions for setting it up in bridge mode. Looks like it's on the Wireless - Basic tab, second drop down.

This depends on your hardware. Research how to setup VLANs on your switch and edge router. Put each WiFi router into a seperate VLAN and tell your edge router to channel traffic from these VLANs over the additional WAN IPs.

Whew. This is a bit of a tricky one given your scenario. First off, router 2 shouldn't share an interface with router 1 that is also on their client-side interfaces. In your example, all 4 devices share the same LAN segment, which as an aside is in the non-routable (edit: across the "Internet") IP address range for the 192.168.x.y family. A better way ...

Your example is flawed. (I saw you edit it, it's still flawed.) In your example, Router 1 and 2 are on the same subnet (i.e. they have the same subnet mask). So Computer 1 is NOT going to send anything out of the default gateway, it is simply going to throw the packet out of the NIC and expect that a switch or the medium will get it to Computer 2. Now, if ...

I think I found an answer to your question. It looks like 10.0.0.1/8 is known to make some routers unresponsive. Try doing a 30/30/30 reset and using 10.0.0.1/24 http://lists.pfsense.org/pipermail/list/2011-November/000813.html

Yes, that’s possible. Open the “Network and Sharing Center”, select “Change adapter settings” (on the left). In the view that comes up now, select both your wired and wireless connection, right-click on one of them and select “Bridge Connections”. A guide with pictures is also available here.
