## Notes on specific pkgsrc binary packages 

- NMAP  

Fixed multiple QNX-specific issues:libpcap (getaddrinfo, atomic.h, DLT/LINKTYPE mismatch)
 - Fortified headers (__bvap)
 - libc++ thread/rune detection
 - getopt_long_only
 - sysexits.h
 - get_srcaddr() crash for raw scans



WHAT SCAN TECHNIQUES WORK :
  -sT: TCP Connect()
  -sU: UDP Scan

### TCP Connect ###
[root@qnxpi /data/pkgsrc/net/nmap]# /data/pkg/bin/nmap -sT -Pn -sV --open -T4 www.netbsd.org
Starting Nmap 7.98 ( https://nmap.org ) at 2026-04-04 18:38 +0000
