Debugging and Diagnostic Commands

XORP supports several operational commands in xorpsh that can be used for debugging or diagnostics purpose. The ping <host> command can be used to test if a network host responds to ICMP ECHO REQUEST packets:

 user@hostname> ping 10.3.0.2
 PING 10.3.0.2 (10.3.0.2): 56  data bytes
 64 bytes from 10.3.0.2: icmp seq=0 ttl=64 time=0.281 ms
 64 bytes from 10.3.0.2: icmp seq=1 ttl=64 time=0.244 ms
 64 bytes from 10.3.0.2: icmp seq=2 ttl=64 time=0.302 ms
 64 bytes from 10.3.0.2: icmp seq=3 ttl=64 time=0.275 ms
 user@hostname> ping 10.3.0.2
 Command interrupted!

The ping command can be interrupted by the Ctrl-C key combination. The traceroute <host> command can be used to print the route packets take to a network host:

 user@hostname> traceroute 10.4.0.2
 traceroute to 10.4.0.2 (10.4.0.2), 64 hops max, 44 byte packets
  1 xorp3-t2 (10.3.0.2) 0.451 ms 0.366 ms 0.384 ms
  2 xorp7-t0 (10.4.0.2) 0.596 ms 0.499 ms 0.527 ms

The traceroute command can be interrupted by the Ctrl-C key combination. The show host commands can be used to display various information about the host itself. The show host date command can be used to show the host current date:

 user@hostname> show host date
 Mon Apr 11 15:01:35 PDT 2005

The show host name command can be used to show the host name:

user@hostname> show host name
xorp2

The show host os command can be used to show details about the host operating system: user@hostname> show host os
