Syncthing : Synchronize Files / Directories

Copy files or directories from one location to an another localtion by [Syncthing]. This example is based on the environment like follows. +----------------------+ | +----------------------+ | dlp.srv.world |10.0.0.30 | 10.0.0.51| node01.srv.world | | +----------+----------+ | | | <-------------> | | +----------------------+ sync +----------------------+

[1]	Install Syncthing on all hosts.

# install from EPEL [root@dlp ~]#  dnf --enablerepo=epel -y install syncthing python3-bcrypt

[2]	Configure Syncthing with any user on all hosts.

[cent@dlp ~]$  systemctl --user start syncthing [cent@dlp ~]$  systemctl --user stop syncthing # generate password [cent@dlp ~]$  python3 -c 'import bcrypt, getpass; print(bcrypt.hashpw(getpass.getpass().encode(), bcrypt.gensalt()).decode())' Password: $2b$12$RXw/VJ1vBm..... [cent@dlp ~]$  vi ~/.local/state/syncthing/config.xml # line 54 : change like follows <gui enabled="true" tls="true" debugging="false" sendBasicAuthPrompt="false"> # change to the address this server listens <address>10.0.0.30:8384</address> # set admin user (any name you like) and generated password <user>serverworld</user> <password>$2b$12$RXw/VJ1vBm.....</password> <apikey>cFdXMg.....</apikey> # line 95 : delete the line blow <unackedNotificationID>authenticationUserAndPassword</unackedNotificationID> [cent@dlp ~]$  systemctl --user start syncthing

[3]	If Firewalld is running, allow ports for services.

[root@dlp ~]#  firewall-cmd --add-port=8384/tcp success [root@dlp ~]#  firewall-cmd --runtime-to-permanent success

[4]	On any client computer, go to the configured address of one of your Syncthing hosts and log in with the admin user you configured.

[5]	Click [Actions] - [Show ID].

[6]	Copy the connection ID that is displayed.

[7]	Log in to the other Syncthing host and click [Add Remote Device] in the bottom right.

[8]	In the [Device ID] field, enter the connection ID displayed on the other host, and in the [Device Name] field, enter the name of the host to be synchronized (any name), and click the [Save] button.

[9]	When you return to the host for which you confirmed the connection ID, a message will appear indicating that a connection request has been made. Click [Add Device] to add the host to which you want to connect.

[10]	You will see the host that has requested a connection. Now go to the [Sharing] tab.

[11]	Check the host that requested the connection to synchronize the default folder [/home/(username)/Sync] and click the [Save] button.

[12]	When you return to the host that made the connection request, a message will appear indicating that a synchronization request has been made. Click [Share] to add the folder to be synchronized.

[13]	Now that the synchronization setup is complete, add or remove files on both hosts to verify that they are syncing properly.
