To check if a host is alive, use ping . If your system is configured to send more than one packet, interrupt ping with the Ctrl +C key combination:
[emmy@pc10 emmy]$ ping a.host.be
PING a.host.be (1.2.8.3) from 80.20.84.26: 56(84) bytes of data.
64 bytes from a.host.be(1.2.8.3):icmp_seq=0 ttl=244 time=99.977msec
--- a.host.be ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max/mdev = 99.977/99.977/99.977/0.000 ms
To check the route that packets follow to a network host, use the traceroute command:
[emmy@pc10 emmy]$ /usr/sbin/traceroute www.eunet.be
