gping is a network tool to ping a target from a remote host. it works as client-server arch through gRPC protocol. it doesn't execute the ping shell command at the remote host instead it runs ping through Golang ping library. use cases can be measurement full mesh network latency between nodes / data center or ping targets from different data center without SSH access to remote host.
- ping from remote host through gRPC
- ICMP raw socket and UDP
- ping multiple hosts
- IPv4 and IPv6
- mutual TLS authentication

gping [options] host(s)
options:
--count value, -c value sets ping count (default: 4) [$GPING_COUNT]
--ttl value, -t value sets the IP Time to Live (default: 64) [$GPING_TTL]
--tos value, -q value sets quality of service in ICMP datagram (default: 0) [$GPING_TOS]
--size value sets the number of data bytes to be sent (data + ICMP header) (default: 64) [$GPING_SIZE]
--interval value, -i value sets wait between sending each packet in format ns,us,ms,s (default: "1s") [$GPING_INTERVAL]
--timeout value, -W value sets time to wait for an ICMP reply in format ns,us,ms,s (default: "2s") [$GPING_TIMEOUT]

--privileged, -p enables ICMP privileged mode [server] (default: false) [$GPING_PRIVILEGED]
--logs enables logging [server] (default: false) [$GPING_LOGS]
--help, -h show help (default: false)
--version, -v print the version (default: false)
note: server side supports unprivileged ICMP / UDP (default) and privileged ICMP / raw socket
If you use gping server in unprivileged mode, you need to run the below command on Linux:
sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"
in case of privileged ICMP (it enables w/ -p or -privileged) you should give the raw socket permission by the below or just run by superuser.
sudo setcap cap_net_raw+ep ./gping
