Configuring ports for operation of the Worker server

Perform the necessary steps for configuring ports if a firewall is enabled on the server.

To configure ports for operation of the Worker server:

1. Open access to ports 3128 and 9046. To do so, run the following commands depending on the utilized operating system:
   • CentOS or Red Hat Enterprise Linux:

     firewall-cmd --add-port=3128/tcp --permanent

     firewall-cmd --add-port=9046/tcp --permanent

     firewall-cmd --add-port=705/tcp --permanent

   • Ubuntu:

     ufw allow 3128

     ufw allow 9046

     ufw allow 705

   • Debian:

     apt-get install iptables-persistent

     iptables -A INPUT -p tcp --dport 3128 -j ACCEPT

     iptables -A INPUT -p tcp --dport 9046 -j ACCEPT

     iptables -A INPUT -p tcp --dport 705 -j ACCEPT

   • If you use SUSE Linux Enterprise Server, in the /etc/sysconfig/SuSEfirewall2 file, specify the FW_SERVICES_EXT_TCP="3128 9046 705" parameter.
2. Apply the changes. To do so, run one of the following commands depending on the utilized operating system:
   • CentOS or Red Hat Enterprise Linux:

     firewall-cmd --reload

   • SUSE Linux Enterprise Server:

     rcSuSEfirewall2 restart

   • Debian:

     netfilter-persistent save

   If you are using Ubuntu OS, the changes are applied automatically.

Ports are configured for operation of the Worker server.
