Operating System

Operating System should be x86_64 and one of the following:

  • CentOS 7/8+
  • RHEL 7/8+
  • Debian 9/10+


Please make sure the time is correct, time zone may be any.

Service Management

systemd is used for Service Management , check :

command -v systemctl

(Expect result: /usr/bin/systemctl)


Use psql to check PostgreSQL Connection:

psql -h -U janusec -W janusec

If not OK, refer to Operation Management , PostgreSQL part.

Check version within PSQL Shell:

select version();

The version must be greater than 9.3.


netstat -anp | grep LISTEN | grep ':\(80\|443\)\s'

Janusec will use 80/443 , if other program occupied thest ports, you shoud change it before installation of Janusec.

If listen=true in config.json, Janusec will use 9080/9443 also, used for internal management.

netstat -anp | grep LISTEN | grep ':\(9080\|9443\)\s'

Nodes Sync

In order to sync correctly, requires:

  • Replica node use the correct time, error less than 60 seconds.
  • The node_key in /usr/local/janusec/config.json is the same with Node Management.


Log file is under /usr/local/janusec/log/


Please make sure nftables works well and there are no redundant rules that affect JANUSEC. Refer to Installation.

After JANUSEC started, the rules is like this:

[root@CentOS8]# nft list table inet janusec -a
table inet janusec { # handle 20
	set blocklist { # handle 2
		type ipv4_addr
		flags timeout

	chain input { # handle 1
		type filter hook input priority 0; policy accept;
		@nh,96,32 @blocklist drop # handle 3

More Information

If all above are OK, you can stop the janusec service, and switch to run it under console, to view more output:

#systemctl stop janusec
#cd /usr/local/janusec

If error found, you can sent to the bottom email, or submit an issue on https://github.com/Janusec/janusec/issues
