    Cool tks for the update , I have previously sent 1 shielded ZEN to my node in one translation, preparing for securenode not on testnet , is it necessary to break down to 5 x 0.25 ZEN ?

      It definitely works better to have 3-5 transactions for the shielded ZEN address instead of just one.

        Rolf,

        Just sent the 5 transactions, I don’t have any record in my wallet of them but they all went through as “successful” and they are aren’t showing up when I check the node balance. Does this just need more time?

        I’m assuming there wasn’t an issue going from a T to a Z?

        Thanks

    This is great – thank you. I am however stuck at the certification verification. For some reason, when i run getnetworkinfo, the tls_cert_verified returns as “false”.

    Is it possible this can take some time to kick in? All the certificates are in place and trying as instructed. Thanks

      there was an error in my guide earlier on the cert instructions. I have updated it. Maybe try again?

        Thanks for getting back to me. I have tried the entire process again and still, no luck… “tls_cert_verified”: false

        Is it something to do with running it as a user? Are there any alternatives here?

        The certificate seems to generate just fine, just doesn’t seem to be verified…

        Thanks again.

          Try checking that there are no type-o’s in the tls cert and key paths in the zen.conf file and that you used YOUR paths and not the one in the guides.

          You can test your cert from outside by using openssl from another linux server. For example, to test the cert on one of my systems type:
          openssl s_client -showcerts -connect znode.blockoperations.io:19033

          after you get the cert type Q to exit the session.

          For anyone who continues to get this error, try this, I have got it to true now.
          1) after this
          FQDN=
          echo ” is $USER”
          echo ” is $FQDN”
          sudo cp /home/$USER/.acme.sh/$FQDN/ca.cer /usr/share/ca-certificates/ca.crt
          sudo dpkg-reconfigure ca-certificates
          2) in the GUI popup, the first item “ca..” is not check with a star. I left this as default, however, it seems this needs to be checked.
          3) Do that with the space bar, so that all items are checked with a star
          4) tab to the ok button and then retry the process from there.

    Hey Rolf thank you for inspiring newbies like myself to join the mining pool.

    Would this rig be able to mine BCH?

    Is it feasible that I mine ETH on this rig and trade it for BCH or would I lose out?

        probably. You need to select the unselected ca at the top of the list, tab to the ok, then hit enter. It should accept a new intermediate certificate.

    Hi Rolf,
    Thank you for this awsome guide.

    Unfortunately I’m stuck in part 2.5 at the section:

    When the updated zen files are done compiling, replace the zen node files:
    zen-cli stop
    sudo cp src/zend /usr/bin/
    sudo cp src/zen-cli /usr/bin
    zend

    I get the following error: cp: cannot stat ‘src/zend’ : No such file or directory

    I did a reinstall. TLS is true now. I can test my cert with openssl on port 9033. On port 19033 I get a connection refused.

    When I do a telnet localhost 19033 on the server the connection is also refused

    • Rolf
      October 30, 2017 @ 10:43 pm

      That’s a lot of progress! The node will either listen on port 9033 if it is running on mainnet, or on port 19033 if it is running testnet.

      To change to testnet, stop zend with a `zen-cli stop` command, edit the ~/.zen/zen.conf file and uncomment the `testnet=1` directive, then start the zen node software with the `zend` command.

      It should now be listening on port 19033 and showing testnet:true in the results of the `zen-cli getinfo` command

      If you do a full 1:1 Network Address Translation rule on your firewall it will work just fine. I have some nodes running private IP addresses on the LAN with a firewall providing NAT services.

    My node is registered and up, but states my cert isn’t valid. The node says otherwise when running a zen-cli getnetworkinfo:

    “protocolversion”: 170002,

      That block of text is designed to be pasted directly into the command line.

      It will create the correct file and fill it with the right information without you having to open a text editor at all. Go ahead and give it a try and I think you will like it.

    Hey man great guide!, I just have a couple of questions, maybe they are to obvious and I haven’t understood clearly.

    I wanted to run the node first without testnet, since I don’t have the 50 testnet Zencash yet, if this possible, or testnet is mandatory?.

    The other question is how the node will the the T_Address of the wallet where the 42 Zen are stacked, after sending the 1 Zen transactions split x5? Thanks man

      yes you can run it without testnet. Should run just fine. Tracker won’t work, but the node will.

      Definitely send the funds to the Z_address first, because the change gets send to a different T_address on your wallet

        Hey man, thanks for the reply, I still don’t know if I’m getting it. I just want to be sure of something, I have real ZenCash, I don’t remember where I read that I shouldn’t send real ZenCash to the node. So I haven’t done the part where I have to send 1 zen split in 5 transactions. So that’s why I was asking if it was ok to do this part with real Zen and not tesnet ZEN and run the node without testnet mode.

        If the tracker won’t work, it is still qualify as a secure node to receive payments? Also I haven’t seen where to configure the T_Address (where the 42 ZENs are) to get the rewards, it is when I run the node setup.js command?. Thanks again.

        Hi,

        Same problem as @erbobby here.

        Where to set the staking address?

        It seems like we only put the T-Address when we using the tracker, so the T-address is the address where we put our 42 ZEN in?

        If so, I still didn’t find any information for staking address when we don’t run on the testnet.

        I don’t know how to solve this problem, plz help or just point out where I can get such information.

        Thank you very much!

          It looks like we set the staking address via securenode tracker.

          So if the mainnet is on, the securenode tracker will be updated too?

          Because for now, the tracker is only support testnet

          The process of this article is still persistent when the mainnet is on? Or we have to change something? ( except testnet=1 => #testnet=1 ha)

    cat < > /etc/monit/monitrc
    ### added on setup for zend
    set httpd port 2812
    use address localhost # only accept connection from localhost 
    allow localhost # allow localhost to connect to the server
    #
    ### zend process control
    check process zend with pidfile /home/$USER1/.zen/zen_node.pid
    start program = "/home/$USER1/zen_node.sh start" with timeout 60 seconds
    stop program = "/home/$USER1/zen_node.sh stop"

    This is what I get running the setup without testnet. I already have 1 real ZEN on the Z_address on the node. If I switch to testnet I will loose the ZEN I have there?

    Retrieving zen rpc config….
    This version should only be run on testnet. Please reconfigure zen.conf with testnet=1

    zen-cli z_gettotalbalance

    Why exactly shouldn’t one be root when setting up the VPS?
    Seems weird to add another user and annoyingly use sudo for everything. This is a fresh box, so what’s the big deal? Even if you screw it up, just blow it away and start it again.

    Am I missing something? I mean, *maybe* it’s bad practice versus typing sudo a million times? I guess what I’m asking is whether it inherently compromises the secure node by setting it up as root?

    Hi.. i have been trying to install zencash node and i m following ur tutorial step by stey..

    But when i run the commance

    sudo apt-get install zen # to install zen
    Reading package lists… Done
    Building dependency tree
    Reading state information… Done
    Package zen is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source

    E: Package ‘zen’ has no installation candidate

      I also received this error. I resolved the error by using the 64-bit version of Ubuntu. When I was downloading Ubuntu the 64-bit option said it was for AMD processors but I had an Intel processor. I later found out the though it says AMD only it also works on Intel.

    Thanks for the tutorial, very helpful. I am getting an error with Lets Encrypt. Pretty sure I just don’t know what I’m doing. Does anyone have a tutorial to send on setting that up? Basically, when I enter:

    sudo ~/.acme.sh/acme.sh –issue –standalone -d $FQDN

    I get the error message:

    new-authz error: {“type”:”urn:acme:error:malformed”,”detail”:”Error creating new authz :: DNS name does not have enough labels”,”status”: 400}

    I don’t think I even properly setup the domain or any of that though. Any help would be greatly appreciated! Will donate Zen!

    You need to rebuild the database using -reindex to change -txindex.
    Please restart with -reindex to recover.

      zen-cli z_sendmany “zc_address_old_node” “[{\”amount\”: 0.001, \”address\”: \”zc_address_new_node\”}]”

    Thanks for putting this guide together! Very helpful! I’m using DigitalOcean and trying to set this up as instructed, but have come across an issue when installing the Lets Encrypt certificate.

    I’m stuck here where we input the following:

    FQDN=
    echo ” is $USER”
    echo ” is $FQDN”
    sudo cp /home/$USER/.acme.sh/$FQDN/ca.cer /usr/share/ca-certificates/ca.crt
    sudo dpkg-reconfigure ca-certificates

    Once I enter that into terminal, this is what I’m getting:

    [email protected]:~#
    [email protected]:~#
    [email protected]:~# sudo crontab -e
    crontab: installing new crontab
    [email protected]:~# FQDN=mydomain.com
    [email protected]:~# echo “root is $USER”
    root is root
    [email protected]:~# echo “mydomain is $FQDN”
    mydomain.com is mydomain.com
    [email protected]:~# sudo cp /home/$USER/.acme.sh/$FQDN/ca.cer /usr/share/ca-certificates/ca.crt
    cp: cannot stat ‘/home/root/.acme.sh/mydomain.com/ca.cer’: No such file or directory
    [email protected]:~# sudo dpkg-reconfigure ca-certificates

    On the next step, when I paste this in..

    FQDN=
    zen-cli stop
    cat <> ~/.zen/zen.conf
    tlscertpath=/home/$USER/.acme.sh/$FQDN/$FQDN.cer
    tlskeypath=/home/$USER/.acme.sh/$FQDN/$FQDN.key
    EOF
    zend

    It’s returning this..

    Zen server starting
    [email protected]:~# Error: Cannot find TLS key file: ‘/home/root/.acme.sh/mydomain.com/mydomain.com.key’

    Any thoughts? Greatly appreciated!

    Dear Rolf,
    While putting the instructions together and sharing is a great idea, the instructions themselves are poor and do not produce repeatable results and require end user troubleshooting to check.
    a) instructions should include the full directory paths and not just a “cd” – often i was getting lost and having to trace back which directory I should be in.
    b) Part 3 claims to be a consolidation of part 1 & 2, but this isn’t the case; there are many other steps and setups that would be missed if only a part 3 was completed. There is then some mix and match required between part 2 & 3 in order to wrestle with it and try to get a working config.

    I’m currently going through iterations of builds trying to get my own set of instructions, serially without having to repeat steps.

    hmm okay; for tls_cert_verified = false;

    1) delete the /home//acme.sh & /home//.acme.sh
    2) re-download the scripts and issue the FQDN certificates.
    3) if you have re-created the certificate or re-running thru the config, make sure you untick the ca.crt in “sudo dpkg-reconfigure ca-certificates” save, then re-copy the ca.crt file, then re-enter the “sudo dpkg-reconfigure ca-certificates” and tick. This seems to have changed the tls_cert_verified from false to true

    To be honest, I was quite excited about zencash and the idea of being part of a managed node network. Great I thought something to be involved.

    Alas, I fear its going to end in tears because hardly anyone is going to be able to get a node running based on these instructions. Also, to be honest, it just looks very very very bad indeed.

    I’m a IT consultant of almost 30 years standing. Worked on hpux, solaris, linux, windows, in telcoms, defence, public sector etc etc. Been there done it. Not an expert but I know a bit.

    I’ve spent hours getting this to work on the test network and to be honest, I’ve given up. Its that bad.

    Honestly, Rolf, I know I’m not the only one saying this. Great idea and you like a really clever guy but please get someone to help you with the documentation. At the moment, zencash is a non-runner in my eyes because of this poor documentation.

    First of all, awesome guide ROLF! I’ve been building nodes for the past 6 months and this one was the most fun and free of issues. I had some cert issues but, was able to get past them. Now, my node is up and registered and running but I want to automate some tasks. I went through the monit guide but I’m getting a problem in that when I reboot, the zend service does not automatically start.

    After some troubleshooting, I believe it is because I’m not using the sudo command in front of the zend command in the script. I’ve tried to figure out how to run it but everything I see suggests not using sudo inside the script. I guess it could be something with my user as well but its in the sudo group.

    Here is the line from the zen_node.sh script I’m talking about.

    eval “/bin/su -c ‘/usr/bin/zend 2>&1 >> /dev/null'”

    Any ideas on what I do to get this to work?

    Thanks in advance!

      I wouldn’t do this Mark if I was you, the instructions are not perfect so you will need to be able to troubleshoot when things goes sideways and you need to be able to administer your own Linux server. So if you do not know how to do that then avoid this at all cost.

      Support wise there is none that I noticed so far, slack community is shutdown discord you need to be invited but I haven’t found out how to.

      For me and another mate we are both sysadmins so when we set this up and had problems we bounced ideas between ourselves to figure out the problems.

    Takes quite a long time to figure out that the guide misses 2 things.

    1) After command “sudo apt install monit” you need to start monit in daemon mode by “sudo monit”

    2) Changes in file “/etc/monit/monitrc” missing the parameter “and”, so has to look like:
    set httpd port 2812 and
    use address localhost # only accept connection from localhost
    allow localhost # allow localhost to connect to the server an

    —————————-

    In addition I have a question according to the required “”:
    It is mentioned that this address should be created by the swing wallet and the 42 Zen have to be send to this transparent address.

    Am I right, that the “” could be any created transparent address, not only the one of the node itself (figure out by: zen-cli listaddresses)?
    This means on the node I have a balance of private funds of 1 Zen and on my e.g. windowns client machine with full synced chain the 42 Zen, right?

    Node:
    zen-cli z_gettotalbalance
    {
    “transparent”: “0.00”,
    “private”: “1.0096”,
    “total”: “1.0096”
    }

    Windows client:
    E:\Zen\app>zen-cli z_gettotalbalance
    {
    “transparent”: “42.00000001”,
    “private”: “0.00”,
    “total”: “42.00000001”
    }

    Or have the 42 Zen also be on the node to get a total of ~43 Zen?

      An answer to your question may be in the ZenCash discord group.

      – On the other hand, I wanted to ask you something in particular and it’s the following:
        * the address T_ADDR can be any address?
        * How do I know that my node is synchronized?
        * Does T_ADDR have to be a new address?
        * T_ADDR must not have transactions?
        * My master node appears in the online tracker, I also have the balance of 1.1 ZEN in the masternode’s
      armored address.

        Thank you!!

        Ya tengo mi primer nodo operando y produciendo. Sin embargo hace unos dias cree un segundo nodo en google cloud services. El nodo opera super. Esta up, sin embargo tengo problemas con la validación del certificado en el tracker. He reinstalado, cambiado dominio, y pues al verificar con zen-cli getnetworkinfo, el certificado tls esta marcado como true. Sin embargo no me lo valida el tracker. me sale el siguiente mensaje “Cert Valid: false No peers found yet with connections to this node.” He probado mil cosas, reinstalado letsencrypt, pero no logro conexion. He revisado el firewall el puerto 9033 aparentemente esta abierdo pero nada sigo sin poder validar el certificado. Tendras alguna idea al respecto?

        Gracias de Antemano

        Juan

        Gracias de antemano

    Hi Rolf, Am traing to transfer Zens from Arizen wallet to Z address on the node. That is returning errors on Arizen about Z address being incorrect and that it has to start with Zn. What gives?

      Arizen does not do shielded transactions, only transparent. Use the swing wallet if you want a GUI wallet that can send to shielded addresses.

    Cloud you add the info that we need to have at least 43 ZEN for being able to properly set up a secure node at the top level of your wonderful guide, please ?

    Especially, it is not nice when you have pasted 2 days for being able to set the SSL certificate and you just arrive to the point saying that you need to send 42 ZEN to the T address 😀
