Finally, you can put all that into a shell script so you
never have to type it again.
$ cat > bin/tophosts
#!/bin/sh
sed -rn 's/.*[^0-9]([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+).*/\1/p' ${1+"$@"} |
uniq -c |
sort -n |
tail -n 20 |
sed -r 's/(.*) (.*)/echo \1 \2 `host \2`/' |
sh |
awk '/NXDOMAIN/ { print $1, $2 } !/NXDOMAIN/ { print $1, $NF }'
^D
$ chmod +x bin/tophosts
$ tophosts
30 216-210-236-195.atgi.net.
31 host248.orcasinc.com.
31 211.101.226.193
36 host248.orcasinc.com.
36 relato.pro.br.
... et cetera ...
Whose turn is it to advocate Python today?
Thanks Bob...
I can't get this to work just yet, but I'll play with it some more...
Question (remember - I'm stoopid): where is this script getting the IP
addresses from? I don't understand the first part of:
$ sub='s/.*[^0-9]([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+).*/\1/p'
$ sed -rn "$sub" logfile1 logfile2 logfile3
