To test the reachability of our servers, you can use the ping utility. Example of a successfully established ping connection:
roman@braiins ~ % ping eu.stratum.slushpool.com PING eu.stratum.slushpool.com (220.127.116.11): 56 data bytes 64 bytes from 18.104.22.168: icmp_seq=0 ttl=52 time=29.191 ms 64 bytes from 22.214.171.124: icmp_seq=1 ttl=52 time=59.535 ms 64 bytes from 126.96.36.199: icmp_seq=2 ttl=52 time=21.847 ms 64 bytes from 188.8.131.52: icmp_seq=3 ttl=52 time=56.541 ms 64 bytes from 184.108.40.206: icmp_seq=4 ttl=52 time=28.268 ms --- eu.stratum.slushpool.com ping statistics --- 5 packets transmitted, 5 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 21.847/39.076/59.535/15.716 ms
If for some reason the ping utility is not available, you can also use Telnet instead. Example of a successfully established Telnet connection:
telnet stratum.slushpool.com 3333 Trying 220.127.116.11... Connected to stratum.slushpool.com.
