You will first study a simple Internet ping server written in Python, and implement a corresponding client. The functionality provided by these programs is similar to the functionality provided by standard ping programs available in modern operating systems. However, these programs use a simpler protocol, UDP, rather than the standard Internet Control Message Protocol (ICMP) to communicate with each other. The ping protocol allows a client machine to send a packet of data to a remote machine, and have the remote machine return the data back to the client unchanged (an action referred to as echoing). Among other uses, the ping protocol allows hosts to determine round-trip times to other machines. You are given the complete code for the Ping server below. Your task is to write the Pin...

We are having an issue with COPP dropping our DHCP AND TFTP packets. Cisco Switch 9000 series, we want to move our traffic to this switch but when we do the COPP in the switch keeps dropping our DHCP AND TFTP traffic. I need a example config for allowing traffic for icmp, dhcp, tftp through the copp or find a way to disable that traffic on ports. You cannot disable COPP on the Cisco itself. Older versions you could use skip but not current IOS.

There are a few different libraries in this code that could be useful to other programmers: WebSockets Secure client ICMP package that sends multiple pings simultaneously and measures the results Linux system / performance data collector Remote web shell client

I need a Python programmer to write a small enough .py file, that can either read from .pcap file or from live input.

Objectives - Develop tools that can used on hosts to communicate, send data, files, etc. and create a testbed to demonstrate the approach. - Consider options to detect misuse of ICMP in the ways that have been created above, or by existing available tools. Implement and evaluate detection solutions. - Develop a tool similar to hping or fping. Example: Terms and conditions: * Payment would only be processed once all the mile stones are achieved. * Contract will be made once showing some parts of the script.

Hello, Think We are living in a country in Middle east.... we have servers and we have Run OpenVPN UDP/TCP + Cisco Anyconnect + L2TP on them. also on some of them Wireguard and Outline... everything was ok till last 10 days. from 10days ago till now Government can find OpenVPN , Cisco Anyconnect and L2TP Servers. then they Block the Server IP Address !!! nothing work anymore... SSH , tcp , udp icmp , ping .... they Blocking the IP. Well I think they can Read UDP header packets right? because we changed IP then they blocked after two day!! then re change then re block another IP .... Is there any way available to hide UDP packets from them? I Searched in google and found this: What do you think about UDP2RAW method?! did you tried or what do you think

When the celery client send a task request through the broker: - I want to scrap this url: a.b.c The worker2 should respond and execute the task, and return the result back to the celery client.
