List disk info (Lowercase L)

fdisk -l

List hard drive model, serial and capabilities:

hddtemp -u C -n /dev/sda

What software a web server is running:

curl -I http://www.newegg.com

Kernel buffer messages:

Ping sweep a network with NMAP and just show up IP's:

sudo nmap -PO -sP -PE -n --open -v 10.1.1.1-10 | grep "scan report" | grep -v "host down" | sed 's/Nmap scan report for //g'

Only show down/available IP's:

sudo nmap -PO -sP -PE -n --open -v 10.1.1.1-10 | grep "host down" | sed 's/Nmap scan report for //g' | sed 's/ [host down]//g'

Ping a TCP port:

nping --tcp -p 80,443 www.newegg.com

Stress test packets per second with ICMP (5,000 pings sent at rate of 100k per second):

nping --icmp 10.1.1.1 --rate 100000 -c 5000

QoS EF ping:

ping -Q 0xB8 10.1.1.1

Packet capture (CTRL + C when done):

sudo tcpdump -i eth0 -w testing.pcap

View a packet capture for ICMP:

tcpdump -r testing.pcap -nnvvvSe | grep ICMP

That's about all I got right now.

Some "not so standard" useful IP address stuff:

ip addr show eth0
ip -s link show eth0

Supposedly, those are the new standards, ha ha ha.

Muscle memory has me stuck on

ifconfig

Only the people here will understand how many times I've typed ifconfig instead of ipconfig, or ipconfig instead of ifconfig. So annoying (yes, I annoy myself.)

Annoying yourself is fine. Arguing with yourself is fine... But if you start to hear voices arguing back... Then you should worry.

However, I do feel your pain.

Only voices I hear arguing back are telling me to do dishes, take out the trash, etc....

Those definitely aren't in my head

@scottalanmiller Have you tried glances yet? Just curious.

scottalanmiller

No, I have not.

scottalanmiller

Running it now...

quicky2g

Really liking glances.

My Ubuntu install:

sudo apt-get install python-pip build-essential python-dev
sudo pip install --upgrade glances
sudo pip install bottle

Optional for hardware sensors:

sudo apt-get install lm-sensors
sudo pip install PySensors

Just running "glances" at cli got me the interface. Web server worked like this:

sudo glances -w -B 10.1.1.1

Worked at http://10.1.1.1:61208

Ran a few simultaneous web server instances in the background for local network and Hamachi:

sudo glances -w -B 10.1.1.1 &
sudo glances -w -B 25.25.25.25 &

Definitely going into rc.local now.

Anyone get https working?

That's really nice. I've never used the web version before, just the cli.

Just shows how little I've actually dug into it beyond running sensor-config first, I didn't realize it had another display available. The command line version works so well, and it made so I wasn't jumping between top, iftop and iotop all the time. I was a happy geek.
