Solaris ping report failed packet script
Hello,
on Solaris ping command does not report failed packet as in i.e. Windows (Connection timeout)
Instead it reports the sequence of the sent packet:

Code:
64 bytes from 10.80.4.120: icmp_seq=11. time=36.0 ms
64 bytes from 10.80.4.120: icmp_seq=12. time=35.9 ms
64 bytes from 10.80.4.120: icmp_seq=13. time=38.0 ms
64 bytes from 10.80.4.120: icmp_seq=14. time=35.8 ms
64 bytes from 10.80.4.120: icmp_seq=15. time=35.9 ms
64 bytes from 10.80.4.120: icmp_seq=68. time=50.2 ms
64 bytes from 10.80.4.120: icmp_seq=69. time=35.2 ms
64 bytes from 10.80.4.120: icmp_seq=70. time=36.0 ms
64 bytes from 10.80.4.120: icmp_seq=71. time=35.4 ms
64 bytes from 10.80.4.120: icmp_seq=72. time=35.8 ms

I am trying to create a script ie. while read line in order to check differences icmp_seq so if next_seq-prev_seq > 1 give a message like ping failed. Can somebody please help ?

Any attempts from your side?

Sorry for the code tags. Since it not actually code but a command output I thought it is not required.

I tried while read line to store seq no in perform the subtraction but no luck.

Howsoever, try
Code:
awk '
                {sub (/icmp_seq=/, "", $5) 
                }
NR==1           {last=$5
                } 
$5-last > 1     {print "ping failed"
                }
                {last=$5
                }
' file
ping failed

As Don Cragun always says:
"If you are using a Solaris/SunOS system, use /usr/xpg4/bin/awk or nawk instead of awk ."
