At one time we had to check a number of branches. The following code shows the "ping" as run in a "do" loop followed by the "sed" control file. Run sed with the -n option and "p" something appropriate when you find "0 packets".
Code:
ping -c 1 $in >>mylog1 2>&1


/ ping statistics / {
                    N
                   / 0 packets / {
                        s/^....br//
                        s/ .*//
                        p
                      }
                   }


sed -n -f ping.sed mylog1 > mylog2

If mylog2 exists, the blooming thing is down.

dnping

DNPING(1)						      General Commands Manual							 DNPING(1)

NAME

       dnping - Loopbacks diagnostic packets through a remote node

SYNOPSIS

       dnping nodename [user pass] count
       or
       dnping nodename [options] nodename
       Options:
       [qsv] [-c number] [-i interval] [-p password] [-s size] [-u username] [-w timeout]

DESCRIPTION

       This  utility  sends  to  remote  DECnet  node  nodename the number of packets specified by count to test the link between the two systems.
       Optionally a username and password may be specified for the connection as well as several other options. NOTE that if  you  dnping  another
       Linux box it must have dnetd running.
       NOTE also that dnping is not really like an IP "ping" in that it needs a registered object at the other end to connect to. So, just because
       you cannot ping a machine does not, necessarily, mean that machine is not available, just that the MIRROR object is not available. There is
       not (to my knowledge) a low-level equivalent in DECnet of the ICMP ping message.

OPTIONS

       -c number
	      Number of packets to send (default 10)

       -d     Debug mode (default off)

       -i interval
	      interval between packets in microseconds (default 0)

       -p password
	      Access control password. If this is "-" then you will be prompted.

       -q     Quiet mode (default off)

       -s size
	      size of frame to send in bytes (40 data + 68 hdr)

       -t     timestamps mode (default off)

       -u username
	      access control username

       -w timeout
	      Specifies  a  timeout  (in seconds). If not response is received after this time then dnping will abort. The default is to wait for-
	      ever.

       -v     verbose mode (default off)

EXAMPLES

       Pings 10 packets through remote node "mv3100"

	   # dnping mv3100 10
       Make it look a bit like IP ping:

	   # dnping  -vti 1000000 marsha
