5364 :: Create a firewall / Net IDS with Nim lang

• dmknght (orginal) [2019-10-16T19:13:48+02:00] view original

  Hi everyone! I am wanting to create an application firewall (opensnitch like) with Nim lang and add more features. I also want to monitor packets and block packets by signatures (snort / suricata like). So i searched for packet sniffing lib for nim lang and the only thing i found was libpcap from dom96 github repo which was out of dated and i couldn't use it anymore. So i would like to ask suggestions from nim lang members and devs about using nim lang for my idea. Thanks in advance (sorry for my bad English).

  What traffic capturing speed do you want to achieve? DPDK is a monster, perhaps https://kukuruku.co/post/capturing-packets-in-linux-at-a-speed-of-millions-of-packets-per-second-without-using-third-party-libraries/ is enough?

  Hi! Thanks for your URL. It is really really great. I think i'll try netmap or DPDK
