How do we setup our Steem witness and seed nodes if we have no Ubuntu Linux experience?  What are the exact commands we need to use to become a witness for Steem and get our servers online?  Hopefully this guide will make it ridiculously easy to get started in the command line interface even without ever having used Linux before!  To get to this tutorial, here are a few posts that will lay the foundation to go straight through this guide!  Skip ahead to just view the commands!

1. **Launch a Steem Witness Today** at https://steemit.com/witness-category/@jerrybanfield/launch-a-steem-witness-today shows the list of posts most helpful to me for starting my Steem witness with **no previous experience using Ubuntu Linux** combined with an introduction to what is a witness, why become one, who are witnesses, and what else do we need to do besides maintain the server?
2. **Steem Witness Basic Training** at https://steemit.com/witness-category/@jerrybanfield/steem-witness-basic-training goes deeper into everything about being a Steem witness with answers to every single question I encountered during my first months of learning to be a witness combined with 11 steps to start the server from zero.  The only thing missing from that post is the exact list of commands and troubleshooting which I share in this post!
3. **How to Start Getting Steem Witness Votes** at https://steemit.com/witness-category/@jerrybanfield/how-to-start-getting-steem-witness-votes looks inside the most challenging part of being a witness in earning votes.  I share what I did to get started and now primarily write posts like this to earn more votes along with participating in the comments, steemit.chat, and steemspeak.com.
4. **Steem Witness 14,542 Reporting For Duty** announces the launch of my witness server and campaign at https://steemit.com/witness-category/@jerrybanfield/steem-witness-14-542-reporting-for-duty which I hope is useful in creating a post to use as the URL when broadcasting a new witness to the network!

To begin, we need hosting and access to our Ubuntu Linux server usually with a username or root plus a password.  Long story short I have my hosting with @privex through witness @someguy123 with the server specs listed below.  See more hosting options in [Launch a Steem Witness today](https://steemit.com/witness-category/@jerrybanfield/launch-a-steem-witness-today).

## My Witness and Seed Server Specifications!

64GB DDR4 RAM
2x Intel Xeon E5-2630 V3
2x 240GB SSDs
1Gbit/s connection

These servers are capable of handling a top 20 witness load of a block every 63 seconds with minimal misses and are much higher than are needed to run the very basics at a level less than the top 20!  If we want to make an effective campaign, it is easier to setup and launch our witness with servers able to serve at the very top instead of starting with something cheap and promising to upgrade.  In the event of a disaster or attack, every witness ideally would have servers capable of processing a block every 63 seconds ESPECIALLY every witness in the top 30 and preferably witnesses in the top 50.

# Ubuntu Linux Absolute Beginner Basics!
___
* Left click highlights and copies text.
* Right click pasts text.

# Access the Server!
___
* On Windows 10, download Putty at [https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html) to get connected.  Enter your username and IP address to get started.

![putty initial connection.jpg](https://steemitimages.com/DQmTec9euGpszViqbr8ERNU1BNfz1eaQVA3TcGiETeeuT8e/putty%20initial%20connection.jpg)

* On Mac, go to Applications > Utilities, and open Terminal.  Make an SSH connection to the server by using the syntax below.  Substitute root for your username if needed, say yes to connect, and then enter the password:

> ssh root@IPaddress

# Update and Secure Ubuntu Linux
___
___

## Update Server Password!
___
With access to our server, we start by changing the password a long secure password.  Generate and store the password securely in something like https://www.lastpass.com/ or a password manager to avoid losing access to the server or having the password guessed.

> passwd

Try copying and pasting the password once and then typing it again to verify it works.  Test login with new password by reconnecting to the server.

> logout

## Download Ubuntu Linux Updates and Apps!

Switch to root directory to get to work!

> cd /

Download the updates new programs and text editors!

> sudo apt-get update

Install text editor nano

> sudo apt-get install nano

Change directories and copy the sshd_config file into a new file in case of mistakes with command *cp*!

> cd /etc/ssh/
> sudo cp sshd_config sshd_config_0

List the files in the directory to verify the copy and get comfortable using *ls* to see inside the directory!

> ls

Open the sshd_config file to edit the port and disable root login

> sudo nano /etc/ssh/sshd_config

Change to PermitRootLogin to no because this will disable anyone logging into the server as the root.  DO NOT DO THIS if you have been using root so far up until this point. Instead, stop and create a new user before continuing.

> PermitRootLogin no

Change the port number to a new number between 1000 and 65535 because this will make it difficult to find the port to login on.

> Port #

Use control + o to save and enter to confirm then control + x to exit!

> sudo service ssh restart

## Create Public and Private Keys for SSH Login!
___
1. Get PuttyGen.exe at [https://the.earth.li/~sgtatham/putty/latest/x86/puttygen.exe](https://the.earth.li/~sgtatham/putty/latest/x86/puttygen.exe)
2. Make a strong passphrase for additional security otherwise anyone with the private key file can login
3. Copy the "Public key for pasting" into a pub_key.txt file with notepad.
4. Save public key calling it pub_key.
5. Save private key as private.ppk

We now have three files that help us log into our server which are

1. pubkey.txt
2. pub_key
3. private.ppk

Now we need to get this setup on our server.

## Add the Public Key to the Ubuntu Linux Server!
___

Make .ssh directory or if it already exists and an error comes up, continue to step 2.

> mkdir ~/.ssh

Modify folder access.

> chmod 700 ~/.ssh

Change directory into the folder.

> cd ~/.ssh      

Create or read a file for the key.  If blank, paste the public_key.txt in.  Save/overwrite the file and close.

> nano authorized_keys

Load the updates.

> sudo service ssh restart

Set so only root can access.

> chmod 600 authorized_keys

> logout

## Test login with the key to verify it works!

Go to SSH and auth in Putty.  Put the private key file in along with the rest of the server info and save as a preset.

![putty private key file.jpg](https://steemitimages.com/DQmU1YXh2FEwbFGHBkmaZksiUaidnKRKGLRMzdR59bfQ1rD/putty%20private%20key%20file.jpg)

Verify the key works to log in so we can continue by disabling password logins.

## Disable Password Logins!
___

Open the sshd_config to disable password access.

> sudo nano /etc/ssh/sshd_config

Remove if commented out and overwrite and exit.

> PasswordAuthentication no

Load new protocols.

> sudo service ssh restart

## Remove IPv6 Listening
___

Add AddressFamily inet to the end of the sshd_config file to disable IPv6 listening.

> echo 'AddressFamily inet' | sudo tee -a /etc/ssh/sshd_config

> sudo service ssh restart

## Install and turn on UFW

Install Uncomplicated Firewall and proceed with typing y to continue the installation.

> sudo apt-get install ufw

Check the status to confirm it is inactive.

> sudo ufw status

> sudo ufw default allow outgoing

> sudo ufw default deny incoming

> sudo ufw allow ssh

Set the UFW to allow a customportnumber equals to the port selected to connect with ssh earlier.  For a webserver port 80 or whatever is set needs to be open along with any other program wanting access.

> sudo ufw allow #

> sudo ufw enable

## Avoid Block Misses with NTP to Sync Time!
___

> sudo apt-get install ntp

> cd /etc

Copy the original file in case of problems.

> sudo cp ntp.conf ntp0.conf   

Open the conf file in text editor nano.

> sudo nano /etc/ntp.conf

Add these at the end and overwrite!

> minpoll 5
> maxpoll 7

Enable and restart.

> sudo systemctl enable ntp

> sudo systemctl restart ntp

We now have the server ready to use for a seed node or a witness node!  I started with the seed node because it was good practice and a lot easier.  While a seed node is technically not required to be a witness, it is highly recommended if we want people to take our campaign for witness seriously and vote for us!

# Seed Setup!
___
___

Install Steem Docker by @someguy123 to make installation simple!

> sudo apt install git curl wget

> sudo git clone https://github.com/Someguy123/steem-docker.git

> cd steem-docker

> ./run.sh install_docker

Logout and log back in to get started.

> logout

Change directory to steem-docker to run commands.

> cd steem-docker

>./run.sh install

After the install is complete, download the existing blocks to speed up setup!

>./run.sh dlblocks

When the download finishes, adjust the shared memory.  8 GB is minimum and 12 GB at least is recommended.  Do not use more than you have!

> sudo ./run.sh shm_size 16G

Replay to get up to date!

> ./run.sh replay

Finished with at 100% and showing the newest blocks!  Check with 

> ./run.sh logs

That is it for a seed node!  To get a seed node added to the list at https://status.steemnodes.com/ contact @wackou who maintains this list on [steemit.chat](https://steemit.chat/direct/wackou).

# Witness Setup
___
___

Setting the seed node up is great practice for bringing the witness node online because almost all of the steps to do the seed are the same along with a lot more to do the witness!  If we follow the steps the way I did, we setup the seed node completely first to gain confidence and then start with the witness node from the beginning using the same process for security that we did on the seed node stopping just at the seed node steps and skipping down here instead!  Ready?

## Install Steem Docker and Prepare The CLI Wallet.
___
> sudo apt update

> sudo apt install git curl wget

> git clone https://github.com/Someguy123/steem-docker.git

> cd steem-docker

> ./run.sh install_docker

> logout

> cd steem-docker

> ./run.sh install

> ./run.sh dlblocks

Wait for everything to finish!  If permission errors here or a previous step, back up one level to home/user and chown user:user -R steem-docker to fix.

Next, we get to work making our Command Line Interface or CLI wallet because we need to manage our Steem account with the witness!

> ./run.sh remote_wallet

> suggest_brain_key

Save the public and private key securely for later.  Read all the CLI wallet commands at https://steemit.com/steemhelp/@hannixx42/cliwallet-commands-v0.

Exit the wallet with Control + D and then change the shared memory to a minimum of 8G or recommended at least 12G.  I use 16 GB because I have enough memory.

> sudo ./run.sh shm_size 16G

Overwrite and exit the file to finish.

## Edit Config.ini to Prepare to Launch!
___

Make a copy in case of a mistake!

> cp data/witness_node_data_dir/config.ini data/witness_node_data_dir/config0.ini

Open the config.ini file to edit.

> nano data/witness_node_data_dir/config.ini

Edit in the following format with your witness name instead of mine along with the private key from the CLI wallet saved earlier and the shared file size chosen.

>witness = "jerrybanfield"
> private-key = 5xxxxxxxxxxxxx
> shared-file-size = 16G

In the config.ini, find p2p-endpoint = 0.0.0.0:2001 and delete it because we are not running a seed!  Save and close the file with  press CTRL-X on nano and hitting enter to say yes to saving.

Finally, we disable port forwarding for seeds!

> nano .env

With the file blank, add these lines and save

> PORTS=
> DOCKER_NAME=witness

## Get Online!
___

We are now nearly ready to replay, get synced, and broadcast our witness!  I was so excited to do this and hope you are too!  First, we need to replay the blockchain as we did on the seed to get updated.

> ./run.sh replay

Wait until it is fully synced and bringing new transactions like this.

> ./run.sh logs

1050512ms th_a       application.cpp:507           handle_block         ] Got 31 transactions on block 13566376 by jerrybanfield-- latency: 141 ms

For best performance, check active seed nodes at https://status.steemnodes.com/ by pinging each and building a list in the witness_node_data_dir/config.ini file of the lowest latency nodes.  Then

For example,

> ping seed.jerrybanfield.com

Then edit the seed node list to those pinged successfully at the best speed.

> nano data/witness_node_data_dir/config.ini

If a server restart is needed because of updating the config file, do a quick restart!

> ./run.sh restart

Now time to open the wallet and broadcast our witness which is the final step to getting online!  This assumes you wrote a post to include in the URL which you have ready to use.  If not, use a profile link and update it with the new post or get the post written first!

> ./run.sh wallet

Now we need to make a super secure password to keep our CLI wallet locked because anyone getting into it can use it with our active key!

> set_password "mysupersecurepass"
> unlock "mysupersecurepass"

Import the active key from our wallet on steemit.com under the "permissions" tab and replace with your own.

> import_key 5zzzzzzzzzzzz

With the active key imported, we can now use the CLI wallet to get our witness added to the list!  Here is the command I used with switching out the public key for my own and the username and the URL.  Here was my exact broadcast.  Switch your username, url, and PUBLIC signing key in place of mine.

> update_witness "jerrybanfield" "https://steemit.com/witness-category/@jerrybanfield/steem-witness-basic-training" "STM7462wuSatDmQ6QGkuZPjohJrp2S79xgNjtsDfDgoB2c6HgaAEf" {"account_creation_fee":"0.200 STEEM","maximum_block_size":65536,"sbd_interest_rate":0} true

IF this error comes up

10 assert_exception: Assert Exception
!ec: websocket send failed: invalid state
{"msg":"invalid state"}
th_a websocket.cpp:164 send_message

Then Control + D to close the wallet and open it again.  Immediately broadcast the witness message again before the wallet locks.

## Price Feed Setup!
___

Witness are required to publish a price feed that pegs the SBD to Steem.  Here is the easiest way to do it automatically.  Start by changing directory to the home username such as

> cd /home/jerry

Download Steemfeed from GitHub.

> git clone https://github.com/Someguy123/steemfeed-js.git

Create the steemfeed-js directory to install in.

> cd steemfeed-js

Copy the example config file and add witness name plus active key.

> cp config.example.json config.json

> nano config.json

Close nano and run docker to build the feed.

> docker build -t steemfeed-js

Make sure the witness is synced first before the next step!

> docker run -itd --rm --name feed steemfeed-js

View results at 

> docker logs steemfeed

## Done Setting Up!
___

The beginning of our witness journey is complete and our witness should now be online!  Verify at https://steemd.com/@jerrybanfield except switch your username for mine and look for the witness info in the lower left.  It should say witness with an ID and the data submitted.  Below I will share some trouble shooting and basic errors with solutions I have encountered in the first month of being a witness that I hope are helpful!

# Problems and Solutions!
___
___

## Fastest Way to Get Help!
___
Join the witness channel at https://steemit.chat/channel/witness and start asking questions.  I have received consistent help there from @someguy123 which has helped me solve most problems quickly!

## CLI Wallet Issues!
___

If we lose or update our public key, try to dump the keys again including public and private within the CLI wallet using

> list_keys

If we use multiple wallets or want to make sure our account is synced correctly, use the commend below immediately after unlocking to verify the correct account is synced in the CLI wallet.

> list_my_accounts

control + D to exit the wallet

IF this error comes up

10 assert_exception: Assert Exception
!ec: websocket send failed: invalid state
{"msg":"invalid state"}
th_a websocket.cpp:164 send_message

We waited too long to send the message after unlocking the wallet.  Thanks to @drakos for answering this question and providing the solution!  Close the wallet and reopen and then send again immediately to update.  View all wallet commands at https://steemit.com/steemhelp/@hannixx42/cliwallet-commands-v0


## Miss a block?
___

After a month I just missed my first block fooling around updating my witness after @someguy123 successfully helped me to 19.1 without missing a block.  One of the most basic things to do after missing a block is to restart steem-docker in case it crashed.

> ./run.sh restart 

If it doesn't seem to start getting transactions after 5 minutes, then your blockchain or shared memory is corrupted and you might need to ask for help fixing that.

If a lot of blocks where missed or one was missed a long time ago, check the logs to see if the blockchain is current.

> ./run.sh logs



## Server restart commands
___

If the logs are behind and not getting new transactions, a replay may be needed to catch up after a restart.  Avoid running a replay if the logs are current!

> ./run.sh shm_size 16G
> ./run.sh replay

If known reboot needed, avoid replay with

> mkdir /home/user/shm
> cp -R /dev/shm/* /home/user/shm/

then

> ./run.sh shm_size 16G
> cp -R /home/username/shm/* /dev/shm/


## Steemfeed Troubleshooting
___

If the file is changed with a new active key after starting ...

> docker build -t steemfeed-js
> docker stop steemfeed
> docker rm steemfeed
> docker run -itd --name=steemfeed steemfeed-js

If price feed drops, here is a fix

> crontab -e

#Add this to the end of the file to help it restart

> 0 */2 * * *

> docker restart steemfeed
