The nmap -f --badsum 192.168.1.10 command is most likely to avoid detection by the client's IDS, as it will use two techniques to evade IDS signatures or filters. The -f option will fragment the IP packets into smaller pieces that might bypass some IDS rules or firewalls. The --badsum option will use an invalid checksum in the TCP or UDP header that might cause some IDS systems to ignore the packets.
