Tip #816   Graph connections to hosts

The command below will print a ascii art graph of connections from you are making to different hosts

netstat -an | grep ESTABLISHED | awk '{print $5}' | awk -F: '{print $1}' | sort | uniq -c \
 | awk '{ printf("%s\t%s\t",$2,$1) ; for (i = 0; i < $1; i++) {printf("*")}; print ""}'

You may need to check the output from "netstat -an" to check the host is in the 5th column, if not change the first "awk" to the right column number.
