Verify the Firewall Settings
For the SL4000 and STA to communicate using SCI, the firewall settings must be properly configured.
- Verify the following firewall settings:
- Firewall is running
- Check hosts.allow and hosts.deny files if using those OS services
- REJECT rules are not interfering with the inbound and outbound SCI ports (such as 7103, 7102, and 7026)
- Port forwarding from 162 to 7029 (port 7029 may be different if you have customized it)
- Network router configuration between the STA server and library
To verify, open a terminal session and login as the root user. Issue the following:
# systemctl status iptables # more /etc/hosts.allow # iptables -L
- If needed, use the iptables command to remove or modify the firewall rules to
allow SCI communication. For example:
# iptables -D INPUT 5
WARNING:
Removing or modifying firewall rules can create security risks and must be done by a qualified security administrator.
- Verify the iptables settings:
- Verify iptables rules were been saved correctly using the service
iptables save command.
# service iptables save
- Verify the iptables server is enabled. For example:
# systemctl status iptables # systemctl start iptables # systemctl enable iptables
- Verify iptables rules were been saved correctly using the service
iptables save command.
