A VPN does not prevent the attack -- presumably because the attacker is aware of the server I am using.
If they are in position to monitor your traffic to be able to send RSTs to you, they can just as easily send fake RSTs to the server, which you can do nothing about. Once that's done, the server will stop sending you data anyway, and the resets received ...
The server OS is openSUSE Tumbleweed 32-bit and its DNS server was already configured by YAST2. Taking a look at /etc/named.conf indicates the named working directory:
# The directory statement defines the name server's working directory
Also /etc/named.conf indicates the zone file relative ...
Actually, the problem just required a bit more patience.
In case anyone else has the same question, I'll leave it here.
Right-click on the "Movies" folder icon in "My PC" screen, select "Properties" in the bottom.
Go to "Location" tab, click "Move". In Explorer window, select "Network" and type the ...
If the old router was statically configured to be 192.168.1.2, that means it is still 192.168.1.2 today. It can't have been affected by the DHCP server's change, because it wasn't using DHCP to obtain the address in the first place. (Which is also most likely why it doesn't show up in the "connected devices" list.)
You cannot access it currently, ...
I have a main router from ISP - 192.168.1.1, dhcp enabled, range
33-127. I have connected a secondary router(tp link) as an AP -
192.168.1.2, dhcp enabled, range 128-254. how to fix this ? any alternative on how to run only 1 dhcp to to fix this ?
In a small network like this, you really need just one DHCP server. More than one causes issues as you see....
DHCP server must be setup on a host with a network already configured.
It does not assign the IP for the host it is running on.
So first you have to defined a fixed IP for this host. Then this fixed IP will be the gateway IP for the other PCs you will connect.
Note : as soon as you know how to setup a fixed IP , you have better to begin your test without ...
Calvin Thomas shared some of the greatest wisdom concerning pulling Ethernet cable.. Sadly it is only us Professionals who have pulled lots of cable, throughout many different environments, whom understand the value in pulling LOTS OF SPARE runs.
So let me expand on the topic:
I pull a minimum of 3x what I need; and,
Always give a plentiful extra amount of ...
Any host can disguise as a network printer, as long as it speaks the same protocol – that's how print servers work. Most operating systems will allow you to add a network printer by its URL.
There are a few standard print job submission protocols that are spoken by network printers – IPP (port 631), HP JetDirect (port 9100), and occassionally lpr (port 515).
I manage a Windows 10 Pro system setup as a basic file server for multiple users.
Windows 10 Pro is not designed to be a server operating system. Sure, you can set up file sharing, printing, but you will very quickly hit licensing limits. For example, Windows 10 Pro will allow only 20 concurrent share connections.
Use Windows Server 2019, or a Linux-based ...
NAT is an abbreviation for Network Address Translation.
SNAT is Source NAT, or, NAT for traffic in the direction of Source, or Internal network, to a Public or other network IP translation.
DNAT, similarly, is Destination NAT, for traffic coming from an external Public or other network to a private networks destination, performing an IP address translation.
First, 169.254.x.y is the internal"DHCP not found" address. You cannot connect through that.
Your host wireless connection should show up as Ethernet to a Guest machine. I see that here.
If you use Bridged networking, you can communicate readily between machines.
If you use NAT networking, you can still communicate, but I use IP addressing for this ...
After trying multiple accounts that were in the Administrator group (this is a corporate device), the local Administrator account was used. Once the local Administrator account was logged in, the software successfully installed with the Network option.
There is no reason why the driver should not have respected the Administrator privileges of the domain ...
I also had the same issue for a long time in Ubuntu 18.04 (Your connection was interrupted / Network Change error). How to fix it.
Check Network Settings (Disable IPV6). Further you can execute the following code:
sudo nano /etc/sysctl.conf
and add the following code
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
I think you should also adjust same MTU size in PLC adapters, as well as Fritbox router, otherwise it won't work.
It is not sufficient by reducing MTU on client computers, rather every element of your network.
A low MTU has its pros and cons.
Usually, enterprise networks don't mix routing and Wi-Fi in the first place. If you've reached the point where you need VLANs, then your router should be just a router, with a bunch of standalone Wi-Fi access points connected to it via Ethernet.
So yes, if you want a home lab then get a standalone router, then try connecting your "range extender" ...
The computer can send any kind of data over its network interface – if you're connected to Ethernet, then the OS is in full control of the Ethernet frames that it sends. It's the OS, not the network hardware, that handles IP, ARP, and other protocols.
Rather, the only question is how regular programs on that computer are able to send data without having an ...
First of all, let's make this clear:
The permanent option --permanent can be used to set options permanently. These changes are not effective immediately, only after
service restart/reload or system reboot. Without the --permanent
option, a change will only be part of the runtime configuration.
If you want to make a change in runtime and ...
This is possible to implement with other SSH clients, just more tedious – e.g. with PuTTY (or its command-line counterpart plink) you have to manually start a connection to A, then to B, then to C (or the other way around? I didn't 100% understand.)
In PuTTY, this might be possible by saving connection profiles through the GUI and loading them through plink.
My solution is specific to wired network. If you have two computers on a subnet and each have static ip and if you are trying to ping virtual machine ip on the first computer from the second computer on same network.
From the Virtual Box go to Settings -> Network
Then choose Bridged Adapter from Attached To dropdown menu. Make sure to choose appropriate ...
Try running nslookup against each server specifically.
One problem with bare nslookup is that it does not follow the same DNS server selection logic as Windows itself; rather, it just looks at the first server in the list and always uses that. So if you have multiple servers (which you most likely do, some of them IPv4 and some IPv6) and the 2nd or 3rd is ...
You can install some VPN-server packages like wireguard or openvpn.
I personally use WireGuard due to some reasons using UDP packets.
You can download the script via this link: https://github.com/Nyr/wireguard-install
wget https://git.io/wireguard -O wireguard-install.sh && bash wireguard-install.sh
Then choose a DNS server and a name, ...
There are 3 kinds of technologies for this task. (Within a scope of a single answer, I can only give an overview of them.)
1. Port forwarding
Your home computers have private IPs -- but the router that they are connected to the Internet through likely has a public IP on its external interface (that's true for most home Internet providers). If you find out ...
According to this
IEEE scientific paper, the smaller size you adjust for MTU, the better i.e. less packet loss.
Obviusly you need to config the same MTU on every LAN adapter within your network, for above mentioned approach to work out properly.
Not really suitable for copying big files, but could work in RT apps like small chunks in video streaming or P2P.
Is it possible that ISP didn't provide real public address for me but instead it gave me an address being a result of PAT?
Yes. Many ISPs now use Carrier-Grade NAT (although there are still many which don't).
For example, if your router shows that its ISP-assigned address is from the private 100.64.0.0/10 range, that's definitely an indication of CGNAT.
Is it possible that ISP didn't provide real public address
If ISP use Carrier-grade NAT (CGN), you'all receive an address that is not a pb for standard usage (web, mail) but you'll not be able to host your servers, ...
it gave me an address being a result of PAT
Some ISP supply only IP with only a range of ports (and not fixed public IP). Except if you ...
There were two issues preventing the V3500 shares from being browsed by another computer on the network.
The first was that the a registry subkey had been added:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters, with DWORD values AutoShareServer and AutoShareWks set to 0. This prevented the admin shares from being shared ...
It sounds like the ISP has the DHCP lease time set way too low at 30 minutes, meaning it forces the router to ask for a new IP address too often (at half time = every 15 minutes). I can imagine that if this is the case, their DHCP server is overloaded with requests from all customers, which might explain the delay time. Contact the ISP and tell them that. If ...
Just letting you guys know the issue I faced as I had been looking for a fix and came across this article.

You should just omit
You don't need it for connection within a broadcast domain (switch). Neither should you "make thing up" (the network switch is not connected to a router (does not have Internet acccess)).
On MAC there is a sharing option in system settings ...

I was able to get this to work. I am not sure if you are still facing this issue and my resolution will work for you. But, it is never a harm to try it out.
I noticed the containers that did not have a port to map/bind to the host has this issue of recognizing host.docker.internal to the host's localhost. Hence I used a dummy port for the container that ...
i understand that I need to port forward in order to be able to access it, but then I have an open port and it is my understanding that it is more or less like an open door in the network, is this the case and do I need to worry about such a thing or is it more like assign the port and tell no one
Ports are assigned to individual processes--a process will ...
it is my understanding that it is more or less like an open door in the network
No, that's not how ports work.
Being able to connect to a specific port (TCP or UDP) only lets you talk to the specific service that is listening for connections on that port. So if TCP port 22 on your computer is "open" by OpenSSH, it just goes to the OpenSSH server ...
The other answers are all true, but I'll elaborate a bit to set some more minor details straight.
The first thing to realize is - when you type http://app.example.com/path/to/resource.jpeg in your browser, the first thing your browser does is to use the DNS system to translate from app.example.com to your external IP address (you need to set this up yourself,...
In theory this would be possible easily: the phone already acts like a router, and it could allow the two subnets (USB tethering and Wi-Fi hotspot) to talk to each other; it could even bridge the two into a single subnet if it wanted.
Unfortunately, it seems that Android deliberately makes this impossible by blocking all packets going between the two subnets....
You could configure reverse DNS for all of your host's IP addresses, pointing to the canonical name. Most non-AD Kerberos implementations always use rDNS as part of the name canonicalization.
(The rDNS entries do not have to be global; they only need to be visible to the client. As long as the client can look them up, they don't even need to be in DNS – in ...
Some providers won't allow you to modify the router connected to their service to forward incoming packets to a particular internal IP:PORT.
AT&T does this on their fixed wireless, for example and last I looked Cox did the same kind of thing.
If they do, then it depends on the router and what s/ware it's running. If it has a DMZ setting you should be ...
Do I need to be running a DNS server [to do this]?
No. You need to be running a reverse proxy. Apache or nginx are both web servers that can be used for this purpose.
In short, you would create either a virtual host (Apache) or server block (nginx) for app.example.com, which would then be set up to forward requests for app.example.com to e.g. http://192.168....
This is a more complex question because it's not always Windows that makes this decision, so it's not always Windows that must be forced to prefer one vs the other (short of disabling IPv6 entirely, that is).
In Windows, when a hostname lookup returns multiple addresses, the OS uses an "address label" or "prefix policy" mechanism to sort ...
IPv6 does not inherently make for a bad wireless connection and should generally not be removed from a modern Windows system.
If your wireless is connected to a router using IPv4 internally (192.168.1.x) then it is already using IPv4.
Some cellular connections are now IPv6.
Get a newer, updated driver for your Windows machine, uninstall Wireless, restart the ...
You should assign static IP addresses to all network infrastructure devices and servers. If for some reason, their IP changed due to a lease expiring, you could experience outages and it would make troubleshooting difficult. Just imagine if the DHCP server went down, or someone else accidentally plugged in a device into the network with its own DHCP server,...
The fact that you can enter the admin page from the 192.168.0.x
network only means that it is accessible.
To access it from 192.168.1.x, you must enable Remote Management.
This gives you the ability to access your router from outside its sub-network
in order to view or change its settings.
The manual for the Nighthawk R7000P
specifies this for "Remote ...
