Use acpi and notify-send to report current temperature every five minutes.

works best in a shell script run at startup. It will ping localhost once and output to null, after it does that, acpi is called for temperature in fahrenheit and piped through to another loop that feeds notify-send for a tooltip. After waiting five minutes, it will start over.

ping 8.8.8.8

User: petrus

Functions: ping

Up

Test internet connectivity

8.8.8.8 and 8.8.4.4 are two Google public DNS.

As their address is really simple, it's easy to use this command to test if Internet is reachable.

Beware of large corporate networks however, that may use this address on router's loopbacks interfaces.

Tags: Network ping beep console server daemon rc.local

Up
Down

Make a server's console beep when the network is down

This is like ping -a, but it does the opposite. It alerts you if the network is down, not up. Note that the beep will be from the speaker on the server, not from your terminal.

Once a second, this script checks if the Internet is accessible and beeps if it is not. I define the Net as being "UP", if I can ping Google's public DNS server (8.8.8.8), but of course you could pick a different static IP address. I redirect the beep to /dev/console so that I can run this in the background from /etc/rc.local. Of course, doing that requires that the script is run by a UID or GID that has write permissions to /dev/console (usually only root).

Question: I am not sure if the -W1 flag works under BSD. I have only tested this under GNU/Linux using ping from iputils. If anybody knows how portable -W is, please post a comment.

Check a server is up. If it isn't mail me.

For some reason the 2&>1 does not work for me, but the shorter stdout/stderr redirection >& works perfectly (Ubuntu 10.04).

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)..

for i in {1..254}; do ping -c 1 -W 1 10.1.1.$i | grep 'from'; done

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 flood

A ping flood is a simple DoS attack where the attacker overwhelms the victim with ICMP Echo Request (ping) packets. It only succeeds if the attacker has more bandwidth than the victim (for instance an attacker with a DSL line and the victim on a dial-up modem).

In this command replace 192.168.1.100 with victim IP address.
