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

NY needs to do something to reinvent themselves. They need to look to Europe and build out a serious public transportation system. NY is too deep to go to the low tax systems that Texas or Florida do to inspire growth. They and California need to go European with high taxes and huge social services to make it work. They could do it, if they are smart about it. They need a LOT of rail and they need it to really work, unlike it is today. But the I90 corridor and the ST corridor are so dense and linear that they could, even with all the open space, pull off a European style structure out there if they were smart.

NY city should just become it's own state then the rest of us in upstate NY can quit paying for their turd shaped island. Taxes are high enough already. We just need to be smarter how we use them.

List disk info (Lowercase L)

fdisk -l

List hard drive model, serial and capabilities:

hdparm -I /dev/sda

Hard drive speed:

hdparm -t /dev/sdd

Hard drive temperature:

hddtemp -u C -n /dev/sda

What software a web server is running:

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

Kernel buffer messages:

dmesg

File transfer with active speed:

rsync --progress --recursive source/* destincation

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.

I honestly don't like htop very much. I prefer regular top. I find the output more useful.

htop works much better to see multi-CPU utilization though. Filtering is really nice too.

Hardware commands are always great:

lspci

Anything in /proc

I LOVE LOVE LOVE htop

I use SNMPv3 alot from the CLI:

snmpbulkwalk -v 3 -u myusername -a SHA -A myauthpass -l authPriv -x AES -X myprivpass 10.1.1.1 system

"sl" is one of my favs.

Should I create a new thread for this? Got through the installation and when I ran zerotier-cli /controller to verify installation, I got "missing authentication token and authtoken.secret not found (or readable) in /var/lib/zerotier-one". I tried restarting the zerotier service and also a full reboot of the ubuntu server.

EDIT: I did check the contents of the aforementioned directory and did see the authtoken.secret file but not sure what the other would be if it weren't the same thing...

This should do the trick:

sudo zerotier-cli /controller

My best friend interviewed with that company. They wanted him to build their server and network infrastructure from scratch. He turned down the job to work somewhere else.

LandLine - as to your questions about VOIP or copper - I'm assuming it means the use of a traditional telephone in the home, which would include VOIP if that's tied into your typical home phone. But again, these are crazy questions that need more information before you gather any meaningful information from the data.

Yeah, but landline doesn't MEAN that. If you have a landline over VoIP, would you even know? To a normal user, a landline is a phone to their house rather than their cell phone. Maybe to IT people we would just to the POTS conclusion, but that is not what the question asks nor what non-technical people would even be able to determine.

You're right to a non-technical person Laneline means your normal home phone. I know I am using VOIP, because Cox home telephone service is VOIP converted to copper in the home.

These days, tons of people are on VoIP and have no idea. Maybe half!

It totally makes since, why manage two separate networks if you don't absolutely need to.

I think some of these old school voice guys still want a security blanket where they don't have to think about a data network. Guess I can understand to a degree but you have to keep evolving to stay relevant.

@scottalanmiller said:

Why are the lengths of the bars different? There was nothing to indicate what the length indicated. Seems fishy.

Think I just figured it out. If you read the small print they had 1,006 adults in the survey but not all of them matched each category so the pool of answers was less for some.

@scottalanmiller said:

They mentioned keeping one and losing the other. They don't make sense to ask separately.

They do?

Are you saying that asking if losing the Internet includes phones? Or that losing email is because they lost the Internet?

And where did they find people with consistent ideas as to what they were answering? Most people will think that Facebook messaging is a form of email and that email is a form of social media. Maybe they are. So how does one answer?

I always wonder where they find these people too. Can't remember a time when I was ever asked for input on major survey results that come out on the internet or news. Is there like 100 people that just sit in a room all day and answer surveys???

I decided to go with Ubuntu mostly because of @quicky2g posting the screen captures

Happy to help! I only tried doing the server because of @dafyre and his awesome scripts!

That's surprising. Every Proliant we've ever had, including DL380s, has been staggeringly loud.

~That's because whoever sold him the server took half the fans....

Ha I double checked

And.... they really did steal them?

Oh no, haha they're all there.

Maybe they're clogged with dust and don't spin anymore.

Or someone stuck a cat in your server

I've got my own little fan club now, though. I took pictures of what I had for lunch and showed it around to everybody. Now I'm being followed by a policeman, a hot nurse, and two guys in white suits that are carrying handcuffs and straight jackets.

Lolololol....but we all want to know more about the hot nurse

Tell the guys in white suits to give her the handcuffs.

I need a distraction from other things I am working on today and I was thinking about trying to stand up a zero tier controller in a VM. Which linux distro should I use?

CentOS, Suse Leap and Ubuntu would be my suggestions.

Wasn't too bad on Ubuntu server:

Dependencies for build

sudo apt-get install git make gcc g++ libsqlite3-dev

For API and script stuff

sudo apt-get install curl php5-cli php5-curl

Install

git clone https://github.com/zerotier/ZeroTierOne.git
cd ZeroTierOne
make ZT_ENABLE_NETWORK_CONTROLLER=1 installer
sudo ./ZeroTierOneInstaller-linux-x64-1_1_2
sudo service zerotier-one restart

I have been thinking about this board:

http://pcpartpicker.com/part/gigabyte-motherboard-gaf2a88xmd3h

• Micro ATX
• Supports up to 64GB of RAM.
• Has RAID (I don't intent to use it)
• OnBoard Ethernet 1 x 10/100/1000 Mbps
• ONBOARD USB 3.0 HEADER(S)
• 8 SATA 6 GB/S Connectors

Why build a server without RAID?

Software RAID and XenServer work very nicely together.

That's not without RAID, though. that's still with RAID.

I always assume when someone says without RAID they mean without hardware RAID. I think that was the correct assumption in this case.

that's a really weird way to say that you want RAID.

Do you want dinner?

No

Hey, where is my food?

You said you didn't want dinner!

I meant... I didn't want a salad.

huh?

I was thinking the same - if I see no mention of RAID, or a specific request for no RAID card, I'm pretty much assuming there is no RAID. I would never assume they are using software RAID - it's just no that common in the SMB world.

And yet it is common enough that anyone mentioning building their own storage is almost assumed to be choosing ZFS specifically to do software RAID. To the extent that nearly every discussion in SW comes down to a complete assumption that you would disable hardware RAID and run software RAID instead.

In some regards, it is completely ignored in the SMB. And in certain groups in the SMB it is so common as to be blanket assumed.

Who uses ZFS? Is that really that common?

Was it the creator of ZFS that murdered someone or is that another Linux technology? Can't remember.

Wasn't that Mcafee?

I was thinking of ReiserFS.
