I'm wondering if I can use netcat to listen to a UDP port and display ALL incoming packets, no matter where they're from. If I just do 'nc -u -l 1234' then netcat will listen for incoming packets and connect() to the source address of the first one it sees (I can see this w...
Description When I try to connect to a netcat server running in a container through an exposed port from the host, I cannot connect to the server. This happens only in rootful mode. Steps to reproduce $ limactl shell default $ sudo syste...
No worries, I was confused by the bit about "tried to configure VS Code using a port number and server address" - I thought you had it set up that way from both ends, and it worked. If you use attach-to-PID, host & port shouldn't be specified, since they're automatically configur...

I don’t fully understand what you want to achieve with the netcat test. Why do you expect port 5900 to be open? If you have not changed the settings in server.cfg, you should have port 4000 open on Ubuntu and connect to the iPhone there To check what ports are open on Ubuntu, us...
显然,如果攻击者把源端口修改为20或者53,就可以摧毁防火墙的防护。在使用UDP扫描时,先使用53号端口;使用TCP扫描时,先使用20号端口。注意..., Xmas Tree,Null和UDP扫描. 端口扫描(Port Scanning) 一个tcp连接扫描使用"-sT"命令如下: nmap -sT 192.168.7.12 隐蔽扫描...
This program successfully connects and sends the message to the netcat listener. Here is the KEXT that emits error 47 on sock_connect. Because of the error, I did not bother to include the send function. /* Follow the guide here: https://developer.apple.com/library/prerelease/mac/documentat...
