Cellframe Node usage Wiki

This guide will work on Debian/Ubuntu

Build from sources:

Linux Prerequsites

To successfully complete of the build, you need to have the following packages to be installed (packages are named as in Debian GNU/Linux 10 "buster", please found the corresponding packages for your distribution):

• libsqlite3-dev
• libmagic-dev
• libz-dev
• traceroute
• build-essential
• cmake
• dpkg-dev
• debconf-utils

Please use the command below to install dependencies listed above

sudo apt-get install build-essential cmake dpkg-dev libz-dev libmagic-dev libsqlite3-dev traceroute debconf-utils xsltproc libpq-dev

MacOS Prerequsites

Install latest XCode from App Store or directly from official Apple site. Install Homebrew from brew.sh, if you have Apple Sillicon chipset pls setup it to /opt/homebrew as recommendent on the Homebrew site. Then install cmake and sqlite

brew install cmake sqlite3 zlib

Generaly thats all what you need

Get all cellframe-node sources

This command fetch sources from gitlab and build them.

git clone https://gitlab.demlabs.net/cellframe/cellframe-node.git --recursive

Build cellframe using cmake framework

Get into directory with cellframe-node and execute the following commands

mkdir build
cd build
cmake ../
make -j$(nproc)

-j$(nproc) nrpoc parameter depends on your machine capacity - number of processor cores. As a result, you should be able to fine make files in your build folder which will be used by cpack command to create an installation package.

Build cellframe-node packages for MacOS

Right now you can just type make install and it will install all the files in your system at /Applications/CellFrameNode.app

Build cellframe-node package for Linux

Use the following command cpack from the build directory to create cellframe-node installation package:

cpack

Install from local package

If everyting went well you should be able to find the following file in your build folder cellframe-node-5.2-0-Debian-21.10-amd64-impish-dbg.deb

Please use dpkg command to install it:

sudo dpkg -i ./cellframe-node-5.2-0-Debian-21.10-amd64-impish-dbg.deb

In some cases there is a following command required to be executed

sudo apt --fix-broken install

Install from DemLabs official public repository

• Create file /etc/apt/sources.list.d/demlabs.list with command sudo nano /etc/apt/sources.list.d/demlabs.list with one line below

• For Debian 11:

  deb https://debian.pub.demlabs.net/public bullseye main
  

• For Debian 10:

  deb https://debian.pub.demlabs.net/public buster main
  

• For Debian 9:

  deb https://debian.pub.demlabs.net/public stretch main
  

• For Ubuntu 18 (Bionic):

  deb https://debian.pub.demlabs.net/public bionic main 
  

• Then download public signature and install it:

  wget https://debian.pub.demlabs.net/public/public-key.gpg
  sudo apt-key add public-key.gpg
  

• Then update your apt cache and install the package (apt-transport-https should be installed):

  sudo apt-get update
  sudo apt-get install cellframe-node
  

During installation it asks some questions

Debian package questions

All this could be changed after in configs

• Auto online If true, the node goes online after he starts and then try to keep this state automatically

• Debug mode If true - produce more log output in files. Suggested to set true until the testing period

• Debug stream headers Dump stream headers in logs, set it true only if you want to get more debug information about stream packages passing through. Suggested false for almost everybody

• Accept connections Enable/disable listening network address. Set false if you don't want to accept network connections to your node

• Server address Network address used for listentning. Set 0.0.0.0 if you want to listen all network interfaces on your computer

• Server port (optional, usually don't ask) Server port, 8079 by default but sometimes better to set it to 80 or 443 to masquarade service as web service.

• Subzero: Enable network Set true if you want to connect your node with Subzero (testnet)

• Mileena: Node type (role) Select node type (or node role) from suggested list with short descriptions. By default suggested to select full (testnet)

• Minkowski: Enable network Set true if you want to connect your node with Minkowski (KelVPN testnet)

• Bacbone: Enable network Set true if you want to connect your node with Backbone (Mainnet)

How to configure VPN service share

To share VPN service you must have a node with master role.

Node base configuration

Open /opt/cellframe-node/etc/cellframe-node.cfg with command sudo nano /opt/cellframe-node/etc/cellframe-node.cfg and find next section:

# VPN stream channel processing module
[srv_vpn]
#   Turn to true if you want to share VPN service from you node
enabled=true
#   List of local security access groups. Built in: expats,admins,services,nobody,everybody
network_address=10.11.12.0
network_mask=255.255.255.0
net=KelVPN
wallet_addr=
receipt_sign_cert=my_awesome_cert

Turn enabled parameter to true thats enable VPN service on your node. Then, the next lines network_address and network_mask usually you don't need to touch. Default configuration reserves network addresses for 254 connections at one time, if you have more - change network mask to smth like 255.255.0.0 and network address to 10.11.0.0 thats gives you 4095 local addresses. Thats important - all the addresses are local and used only inside virtual private network (VPN). For this address and mask also should be configured OS - should be present DNS server, switched on IP4 forwarding and configured NAT. Example of such configurations are below. The next line net sets the name of the network on which the service will be shared. Line wallet_addr sets the address of the wallet to which the payment for the service sharing will be sent. Line receipt_sign_cert sets the name of the certificate for signing receipts. Must match the master node certificate.

Pricelist config

To set the price for VPN services, you need to create an order with the corresponding values. An example of creating an order will be presented below. If you do not create an order and enable VPN sharing the service will not start. To share service for free turn allow_free_srv parameter in [srv_vpn] section to true and create order with zero price.

DNS server install

Install DNS server, it could be any other than Bind9 but for example we will use exactly thats one - did we test this with any other? at a least a couple of others?

sudo apt-get install bind9

Switch on IPv4 forwarding

Open /etc/sysctl.conf with command sudo nano /etc/sysctl.conf and find line

# Uncomment the next line to enable packet forwarding for IPv4
#net.ipv4.ip_forward=1

Uncomment net.ipv4.ip_forward=1 as the comment above suggests. Then after you've changed them and saved changes, implement them with:

sudo sysctl -p

Then after reboot they will be implemented automatically - do we need to specify a reboot command?

Configuring firewall with NAT

Easiest way is to install arno-iptables-firewall with the next command:

sudo apt-get install arno-iptables-firewall

It would ask next questions:

• Do you want to manage the firewall setup with debconf answer Yes
• External network interfaces answer with you network interface thats used for internet access. Usually its eth0 or wifi0 but could be different, examine you network configuration first.
• Open external TCP-ports answer 8079 or what the port do you configured for cellframe node when it was installed
• Open external UDP-ports: answer same as in previous
• Internal network interfaces answer tun0 if you haven't configured any other VPN servers. If they are - find what the tunnel number is biggest and list all of them here with your tunnel name (tun<max number plus 1> )
• Internal subnets here should be network_adddres/network_mask from VPN service configuration, 10.11.12.0/255.255.255.0 in our example
• Should be restarted answer No becase we need some more configs

Now lets increase config ask level and reconfigure the package with the next command:

sudo dpkg-reconfigure -plow arno-iptables-firewall

For answers where you'll see right answers just press enter to skip them. Then the next questions should appears:

• Is DHCP used on external interfaces? usually answer Yes, answer No only if you have static network configuration for external connections
• Should the machine be pingable from the outside world? answer Yes because we use pings for network speed measurements
• Do you want to enable NAT? answer Yes
• Internal networks with access to external networks: here you list internal networks again, 10.11.12.0/255.255.255.0 in our example
• Should the firewall be (re)started now? now answer Yes and have everything ready for routing

How to run

If the node is installed in your system you need only to check it if its runned on your system

  sudo service cellframe-node status

And if its not runned - start it. Start after reboot should be automaticaly executed.

  sudo service cellframe-node start

To stop it use the next command:

  sudo service cellframe-node stop

How to publish service in network

Obtain node address

First you need to publish you public IPv4 and/or IPv6 addresses (for current moment we support only IPv4)

sudo /opt/cellframe-node/bin/cellframe-node-cli net -net minkowski get status

It should print smth like this

Network "minkowski" has state NET_STATE_SYNC_CHAINS (target state NET_STATE_ONLINE), active links 3 from 4, cur node address 374C::CEB5::6740::D93B

Publish IP address in nodelist

Look at the end of address, thats you node address, 374C::CEB5::6740::D93B use it to update information about your node, as in example below:

sudo /opt/cellframe-node/bin/cellframe-node-cli node add -net minkowski -addr 374C::CEB5::6740::D93B -cell 0x0000000000000001 -ipv4 5.89.17.176

Here is cell 0x0000000000000001 used by default until we haven't finished cell autoselection. Then ipv4 address is 5.89.17.176 replace it with your public IPv4 address. Same could be added ipv6 address with argument -ipv6

Create order for VPN service

To say world that you have VPN service you need to place order. First lets see the market, what orders are already present:

sudo /opt/cellframe-node/bin/cellframe-node-cli net_srv -net KelVPN order find -srv_uid 0x0000000000000001 -direction sell

It should print list if you've syncronized well before (should happens automatically by default) Anyway, lets create our order, changing price in it if you see in list thats market changed and you need to change prices as well. Here is exmaple based on our pricelist in previous examples: sudo /opt/cellframe-node/bin/cellframe-node-cli net_srv -net KelVPN order create -direction sell -srv_uid 1 -price_unit SEC -price_token KEL -price 100 -units 3600 -node_addr 374C::CEB5::6740::D93B -cert my_awesome_cert -region Russia -continent Europe

And then you just wait some for network synchronisation and your order will see everybody. Next restart your node. Provide the hash of your order to the network administrator so that your node appears in the clients list of servers.

Description of arguments

• -direction buy or sell, for VPN service publishing it must be sell
• -srv_uid Service UID, for VPN service set 1
• -price_unit Set SEC for Seconds
• -price_token Token ticker
• -units The number of units in one portion of the service, in this example 3600 seconds
• -price Price for the number of units specified in the parameter -units. In this example 100 datoshi for 3600 seconds of service. To share VPN service for free set this field to 0.
• -node_addr Address of node
• -cert Certificate of master node
• -region The region in which the node is located
• -continent The continent in which the node is located

More details about order operations you could find with call sudo /opt/cellframe-node/bin/cellframe-node-cli help net_srv More details about cellframe node commands in call sudo /opt/cellframe-node/bin/cellframe-node-cli help

SubZero testnet

Create wallet and token request

1. Install node according instructions above.
2. Create wallet

    cellframe-node-cli wallet new -w subzero_wallet
    Wallet 'subzero_wallet' (type=sig_dil) successfully created

3. Get wallet address:

cellframe-node-cli wallet info -w subzero_wallet -net subzero 
addr: mJUUJk6Yk2gBSTjcDHXxAerggncSK7DP8ZViVG2zrtbuW6uiCtTvXXn9kdcoBadGeBiujC7VsfemGv5BLbq2zcxoCR8GVRKfCmLtaedd
network: subzero
balance: 0

4. Send wallet address and request for tCELL amount of money to telegram channel: t.me/cellframe_dev_en
5. Waiting for answer from admin and execute command for network chains and gdb syncronization:

cellframe-node-cli net sync all -net subzero

6. See wallet balance:

cellframe-node-cli wallet info -w subzero_wallet -net subzero 
wallet: subzero_wallet
addr: mJUUJk6Yk2gBSTjcDHXxAerggncSK7DP8ZViVG2zrtbuW6uiCtTvXXn9kdcoBadGeBiujC7VsfemGv5BLbq2zcxoCR8GVRKfCmLtaedd
network: subzero
balance:
	5500000.000000000 (5500000000000000) tCELL

Balance replenishment

If you want increase amount of tCell on your wallet, you can wrote about it to SubZero admin.

Tokens transfer

1. You can transfer tokens from your wallet to other wallet. For doing this you need to know address of 2nd wallet. Execute command

cellframe-node-cli tx_create -net subzero -chain support -from_wallet subzero_wallet -to_addr rTDbDdeStfpodpLUevvYaxJBh2k739fjwusqtmAU72VoUCm88ERPw555jHXtrkoEGJfYEZ7Mmwssc3ajijG9eEqEZxV2FmZvYcvnAVZz -value 32100000
        transfer=Ok
        tx_hash=0x4E6D540F86CD46CBFA551F219A04BA2248FF474BB795EB5B2C524299458AD709

• to_addr - address of 2nd wallet (you can see it using command cellframe-node-cli wallet info -w <wallet_name> -net subzero )
• value - amount of tokens

2. Execute command for database syncing

cellframe-node-cli net sync all -net subzero

3. Waiting for a while root node have processed you request
4. Don't create more then one request on balance changing, until you get confirmation about processing current request. That requests will not be processed (it can be fixed in future)

and see your updated balance

cellframe-node-cli wallet info -w subzero_wallet -net subzero

Node notes

1. Token declaration operations, executing on node client (token_decl command) will be approved manually.
2. Token emission operations (token_emit command) will be processing automatically only for token owners.
3. Transactions (tx_create command) will be automatically processing as usual.

Remove cellframe-node

In order to remove cellframe-node, use the following command

sudo apt-get remove cellframe-node
