Record Route 

Records route. Turns on the IP record route 
option, which will store the route of the 
packet inside the IP header. 

Use Broadcast Address 

Allows pinging a broadcast message. 

Adaptive Timing 

Adaptive ping. Interpacket interval adapts to 
round-trip time, so that effectively not more 
than one unanswered probes present in the 
network. Minimal interval is 200 msec. 

4.  Type values for how many seconds the ping command will execute, 

how many ping requests are sent, and the size for the ping packets. 
Default is 56, which translates into 64 ICMP data bytes when 
combined with 8 bytes of ICMP header data. If left blank, defaults are 
used. Optional. 

5.  Click Ping. If the results show a series of replies, the connection is 

working. The time shows you how fast the connection is. If you see a 
"timed out" error instead of a reply, the connection between your 
computer and the domain is not working. See 

 

(on page 278). 

6.  Press Ctrl+C to terminate the session. 

 

Traceroute is often used for network troubleshooting. By showing a list of 
routers traversed, it allows you to identify the path taken from your 
computer to reach a particular destination on the network. It will list all 
the routers it passes through until it reaches its destination, or fails to and 
is discarded. In addition to this, it will tell you how long each 'hop' from 
router to router takes. This can help identify routing problems or firewalls 
that may be blocking access to a site. 

 

1.  Choose Operation > Network Interfaces > Traceroute. 

2.  Enter the IP address or hostname of the target you wish to check in 

the Traceroute Target field. 

3. Select: 

Optional. 

 

Verbose 

Verbose output, which lists received ICMP 
packets other than TIME_EXCEEDED 
and UNREACHABLEs.
