PRING -- ICMP Ping implemented in Rust
This project is just for fun, scratching an itch around fiddling with ICMP and Rust.
The command supports a subset of the usual ping commands:
-4, --ipv4-only Use IPv4 only
-6, --ipv6-only Use IPv6 only
-c, --count <count> Number of ECHO_REQUEST packets to send
-I, --interface <interface> Source interface name to use for sending packets
-i, --interval <interval> Interval in seconds between sending each packet [default: 1.0]
-s, --payload-size <payload-size> Packet paylod size [default: 56]
-t, --ttl <ttl> Time-To-Live count [default: 128]
Running PRING
The program uses raw sockets for ICMP, and therefor needs additional permission to run for a normal user. This adds the necessary permissions:
$ sudo setcap cap_net_raw=eip target/debug/pring
Caveats
The IPv6 implementation is not perfect. Occasionally on the receiving end, the utility captures Router Solicitation and Router Advertisement messages.
