Wireshark sounds like what you want actually. There is very little framing or structure to WebSockets after the handshake (so you want low-level) and even if there was, wireshark would soon (or already) have the ability to parse it and show you the structure. Personally, I often capture with tcpdump and then parse the data … Read more
When you run WSL-2, a machine like a vitural machin run on your window device. Windows will create a local network, same your LAN, and connect WLS-2 to this network. On your WSL2, you can run ip a | grep eth0, result look like: 5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default … Read more
An IP address ending in .0 is perfectly legal these days. However, some devices (and firewall policies) believe that it isn’t. In the old “classfull” addressing scheme, IPs from 192.0.0.0 to 223.255.255.255 were considered “class C” space, i.e. they had an implicit subnet mask of 255.255.255.0. So, back then, you couldn’t actually have a .0 … Read more
I wouldn’t say that something uses a wire-level protocol or doesn’t – I’d talk about which wire-level protocol it uses. Basically, if something’s communicating with a remote machine (even conceptually) then there’s some data going across the network connection (the wire). The description of that data is the “wire-level protocol”. Even within that, you would … Read more
Give the guest two network adapters, one NAT and the other Host-only. The NAT one will allow the guest to see the Internet, and the Host-only one will allow the host to see the guest. One of them also allows the guest to see the host. I’m not sure which, but I know it works … Read more
Based on the output provided, the box has 2 network interfaces, 1 is the default NAT and the other private – ask you said. The reason why you are not able to access the web site hosted within the VM thru the private interface: it could be that host eth0 or wlan0 IP address is … Read more
Adding the host-flag with value “0.0.0.0” should allow you to access the webserver from any device on your local network. This should work: ng serve –host 0.0.0.0 For an explanation: https://github.com/angular/angular-cli/pull/1475#issuecomment-235986121
In case of ssh port, Vagrant solves port collisions by itself: ==> ubuntu64: Fixed port collision for 22 => 2222. Now on port 2200. However, you still can create unavoidable collision by: Creating first vagrant env (it will get port 2222 for ssh) Suspend that env (vagrant suspend) Create second vagrant env (it will again … Read more
Editing the DNS nameserver in /etc/resolv.conf file helped me. Change your existing nameserver to google nameserver i.e., x.x.x.x to 8.8.8.8 Comment your nameserver IP and add something like this : #nameserver x.x.x.x nameserver 8.8.8.8 should work.
A TCP/IP connection is always made to an IP address (you can think of an IP-address as the address of a certain computer, even if that is not always the case) and a specific (logical, not physical) port on that address. Usually one port is coupled to a specific process or “service” on the target … Read more
