When reviewing the magma guide, you may stumble across some unfamiliar concepts and highly technical terms. If you encounter an undefined term that is difficult for you to understand, please feel free to open an issue to request the definition be added to this glossary. Similarly, more experienced users should feel free to contribute and add new terms to the glossary whenever they see fit.
This glossary, like all other sections of the magma guide, will be updated on a rolling basis.
Ping is a tool used to send network packets (
ICMP ECHO_REQUEST) to a
destination host and waits to elicit a response (
ICMP ECHO_RESPONSE) in order
to determine if the destination host is reachable and the round-trip packet time
taken to reply.
Example output of ping tool to
PING magma.lavafeld.org (22.214.171.124) 56(84) bytes of data. 64 bytes from 126.96.36.199: icmp_seq=1 ttl=54 time=22.7 ms 64 bytes from 188.8.131.52: icmp_seq=2 ttl=54 time=23.5 ms 64 bytes from 184.108.40.206: icmp_seq=3 ttl=54 time=22.9 ms --- magma.lavafeld.org ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 22.798/23.085/23.548/0.330 ms
Traceroute is a tool used to track a packet through the network to a specific destination host. It shows the IP addresses and the round-trip packet times as it traces the route to the destination.
