Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Ping scanning without nmap

Usefull for when you don't have nmap and need to find a missing host.

Pings all addresses from 10.1.1.1 to 10.1.1.254, modify for your subnet.

Timeout set to 1 sec for speed, if running over a slow connection you should raise that to avoid missing replies.

This will clean up the junk, leaving just the IP address:

for i in {1..254}; do ping -c 1 -W 1 10.1.1.$i | grep 'from' | cut -d' ' -f 4 | tr -d ':'; done

Ping sweep without NMAP

This version combines the best of the other suggestions and adds these features:

1. It scans a /16 subnet

2. It is very fast by running the ping commands in the background, running them in parallel.

3. Does not use the "-W" option as that's not available in older ping versions (I needed this for OS X 10.5)

prefix="10.0.0" && for i in `seq 25`; do ping -c 1 $prefix.$i &> /dev/null && echo "Answer from: $prefix.$i" ; done

Ping scanning without nmap

Not really an easier solution. But an example using && for (if last command returned 0). You can use || for (if last command returned other than 0)..
