Download

[Binaries] (https://github.com/42wim/gomphs/releases)

Usage

Needs to be run as root (raw sockets for icmp)
When using hostnames with ipv4 and ipv6 addresses, preference goes to ipv4. (-expand option shows both)

# gomphs
Usage of ./gomphs:
  -c int
        packets to send (default 99999)
  -expand
        use all available ip's (ipv4/ipv6) of a hostname (multiple A, AAAA)
  -file string
        ip addresses/hosts file to ping, space seperated (e.g "8.8.8.8 google.com 2a00:1450:400c:c07::66")
  -hosts string
        ip addresses/hosts to ping, space seperated (e.g "8.8.8.8 google.com 2a00:1450:400c:c07::66")
  -i int
        Ping interval in Milliseconds (default 1000)
  -labels string
        labels matching the hosts, must be the same amount of values as the hosts
  -nocolor
        disable color output
  -port string
        port the webserver listens on (default "8887")
  -showrtt
        show roundtrip time in ms
  -timestamp
        enables timestamp instead of ping count
  -web
        enable webserver

no options

. host is up
! host is down

showrtt

Add -showrtt on commandline

When rtt > 1s it will just show ">1s"
When rtt < 0ms it will just show 0

After 25 pings the header will be repeated

expand

Add -expand on commandline

When using expand this also prints an extra (onetime) header so you know what ip addresses belong to what number. See examples.

webserver

Add -web on commandline

The web GUI is by default available via http://<server-running-gomphs>:8887/stream
Use -port to use another port.

When an IP address/host isn't reachable, this will drop to -10 on the Y-axis.

Examples

using web, expand and showrtt

# gomphs -hosts="facebook.com slashdot.org www.linkedin.com" -showrtt -expand -web

using expand

Facebook resolves into 2 addresses (ipv4/ipv6), see 5 and 6 in example.
When using expand this also prints an extra (onetime) header so you know what ip addresses belong to what number
