NP-toys
My network programming toy projects.
Now projects are mostly from Computer Networking: A Top-Down Approach 's assignments.
I refactor the code and add features I want based on the assignments provided by the book.
代码稀烂，正在学习中

toy Web server
- can handle very simple HTTP request and send response.
- status code: 200, 400, 404 / method: GET are supported.
- very naive. Single-threaded, synchronous.
- been tested on Firefox/Chrome.
- A toy for learning. Might be improved in the future.
UDP ping program
- a simple ping server/client using UDP sockets
- determine round-trip time for each packet
- calculate packet loss rate
toy e-mail client
- a simple SMTP client that can send plain text.
- in other words, a clumsy implementation of reduced
smtplib. - just plain ascii, not support utf8/html/attach yet. May be improved someday.
toy Web proxy server
- a simple multi-threading HTTP proxy
- without tunnelling(CONNECT) support
- it works but is very slow. Trying to figure out why
- have a plan for proxy caching support
ICMP ping program
- a simple ICMP pinger
- output like real ping command
- must have root permission to run because of
socket.SOC_RAW
traceroute program
- a simple ICMP traceroute program
- both ICMP request and UDP request support
RTP/RTSP server
