A modern port scanner and icmp scanner. Fast, effective.
Fast scan network by sending icmp, tcp/udp packets, inspired by nmap but doesn't depend on nmap.

you will need root privileges to execute
you can icmp a cidr，ipaddress, separated by commas, set timeout argument as a global execute time limit, use seconds as unit.
$ sudo ./rscan icmp 1.1.1.1/28,1.0.0.0/24 --timeout 10
rscan|icmp|1.0.0.55|
rscan|icmp|1.0.0.116|
rscan|icmp|1.1.1.12|
....
send 272 ips, receive packets from 272 ips
you can still set a env named RUST_LOG to get more log info
$ sudo RUST_LOG=debug ./rscan icmp 1.1.1.1/28,1.0.0.0/24 --timeout 10
or
$ export RUST_LOG=debug
$ sudo ./rscan icmp 1.1.1.1/28,1.0.0.0/24 --timeout 10
use tcp as argument, add ports options
$ sudo ./rscan tcp 1.1.1.1/28 --ports 80,443 --timeout 10
rscan|tcp|1.1.1.10:443|
rscan|tcp|1.1.1.3:80|
rscan|tcp|1.1.1.7:80|
...
udp scan based on icmp reply with Port Unreachable for udp packets if udp port is not open, please make sure timeout is big enough to receive all icmp for all udp packets, so the udp scan cannot guarantee 100% accuracy.
Each ip limit sends udp packets at least 0.5 seconds apart.
$ sudo ./rscan udp 10.30.6.0/24 --ports 151-165 --timeout=50
rscan|udp|10.30.6.165:161|
rscan|udp|10.30.6.200:162|
...
Use the arp protocol to scan intranet devices
$ sudo ./rscan arp 10.30.6.0/16
rscan|arp|10.30.6.10|0c:73:eb:92:0c:ef|
rscan|arp|10.30.6.14|0c:73:eb:94:5e:ed|
rscan|arp|10.30.6.15|20:ce:2a:70:d0:8a|
rscan|arp|10.30.6.16|0c:73:eb:90:d6:73|
rscan|arp|10.30.6.17|e4:f1:4c:57:84:da|
rscan|arp|10.30.6.18|e4:f1:4c:57:82:62|
rscan|arp|10.30.6.26|00:90:0b:99:85:fc|
rscan|arp|10.30.6.57|ac:1f:6b:e6:33:96|
