Obviously first time poster here. I have been set the task of creating a network diagram for each of our clients in the business i work for. After identifying ip adresses of firewalls name servers and the like im got to the point where i found it impracticle to go through 254 ip address and check for a responce. (Im doing this work remotley through a VPN/Putty combination)
As im new to scripting (Only started about a week ago) im not sure on much of the basics so have been making my way through man pages and google sites all week
So my question. So far, my code is as follows:
Code:
#!/bin/bash
#Author: John Crombie
#Small script to ping all ip's within a range specified and to write to file all ips that return a responce.
echo Debugging!
echo xxx.xxx.xxx.x Successfull Pings:>/home/johnc/Scripts/inprogress/ipSearch/ping.log
#for i in {1..254}
for i in {1..5}
do
ping -c 1 xxx.xxx.xxx.$i>>/home/johnc/Scripts/inprogress/ipSearch/ping.log
done
(Replace xxx with correct IP naturally)
Now the problem. While it does what i want the log files is a little clumsy to go through so i want to do the following:
1. send all ip address with no responce to ping to /dev/null
2. go from the sample output below to just the ip address of the successfull ping attempts.
EXAMPLE:
Before:
PING xxx.xxx.xxx.253 (xxx.xxx.xxx.253) 56(84) bytes of data.
PING xxx.xxx.xxx.254 (xxx.xxx.xxx.254) 56(84) bytes of data.
64 bytes from xxx.xxx.xxx.254: icmp_seq=1 ttl=63 time=33.3 ms
--- xxx.xxx.xxx.254 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 33.368/33.368/33.368/0.000 ms
After:
xxx.xxx.xxx.254
So the thoughts i had on this was that i need to firstly add some additional constraints on the ping command and then to pipe the ping.log file through a grep comman of some kind and finishing of with some sort of restrictive redirection on the results of grep....
But i would really value some input.
Let me know if i can provide anymore info or this inst clear. Or its in the wrong forum?

HOBBITCLIENT.CFG(5) File Formats Manual HOBBITCLIENT.CFG(5)NAME
hobbitclient.cfg - Xymon client environment variables
DESCRIPTION
Xymon programs use multiple environment variables beside the normal set of variables. For the Xymon client, the environment definitions
are stored in the ~xymon/client/etc/hobbitclient.cfg file. Each line in this file is of the form NAME=VALUE and defines one environment
variable NAME with the value VALUE.
SETTINGS
BBDISP The IP-address used to contact the Xymon server. Default: Chosen when the Xymon client was compiled.
BBDISPLAYS
List of IP-adresses of Xymon servers. Data will be sent to all of the servers listed here. This setting is only used if
BBDISP=0.0.0.0.
BBPORT The portnumber for used to contact the Xymon server. Default: 1984.
BBHOME The Xymon client top-level directory. Default: The $HOBBITCLIENTHOME setting inherited from the "runclient.sh" script which starts
the Xymon client.
BBCLIENTLOGS
The directory for the Xymon clients' own logfiles. Default: $BBHOME/logs
BBTMP Directory used for temporary files. Default: $BBHOME/tmp/
BB Full path to the bb(1) client program. Default: $BBHOME/bin/bb.
Commands
Many extension scripts expect a series of environment variables to point at various system utilities. These are included in the file
when the client is built.
INHERITED SETTINGS
Some environment variables are inherited from the "runclient.sh" script which launches the Xymon client:
MACHINEDOTS
The hostname of the local system. Default: Taken from "uname -n".
MACHINE
The hostname of the local system, with dots replaced by commas. For compatibility with Big Brother extension scripts.
BBOSTYPE
The operating system of the local system, in lowercase. Default: taken from "uname -s".
HOBBITCLIENTHOME
The top-level directory for the Xymon client. Default: The location of the "runclient.sh" script.
