Networking scripts

This is my collection of random networking scripts. It started as just a brute force DNS enumerator, but also now has an unnecessarily fast port scanner. I've marked scripts that can pretty easily kill stuff with a *

Convoy *

• Scans any CIDR IP range and port range using AF_XDP linux kernel sockets
• Millions of ports scanned per second with a single core
• sudo convoy -r 0.0.0.0/0 -b 443 or sudo convoy -r 0.0.0.0/0 -b 1 -e 1000 for a range

DNS Enum *

• Scans every permutation of A-Z and 0-9 on a DNS server
• ~3.8 Gibps with 10 processes
• Still slow due to exponential growth
• This is not an optimal approach if the DNS server has PTR records

Port Scanner *

• Scans all non-dynamic ports on a specific /16 subnet in 36 minutes, or the first 1000 in 30 seconds
• ~2 Gibps, ~2 million connections, with 85 cores used (most networks cannot handle this)
