This page describes the ports GroundWork needs and ports on other machines.
Ports GroundWork needs
In some cases, such as configuring firewall rules, it may be useful to know the ports that GroundWork needs, and what they are needed for.
|TCP/22||SSH console access|
|TCP/80||Web interface, GDMA|
|TCP/443||Secure HTTPS access (optional)|
|TCP/4913||Foundation Data Feeders|
|TCP/5432||PostgreSQL (typically, not needed from outside the GroundWork Monitor machine)|
|TCP/5667||NSCA passive check reception|
|TCP/5677||Bronx Event broker remote command reception|
Ports on other machines
Ports on other machines that you might want to allow the GroundWork server to access.
|TCP/22||SSH check access|
|UDP/161||SNMP check access|
|UDP/162||SNMP Trap forwarding|
|TCP/5432||PostgreSQL (used on a remote database server)|
|TCP/5666||NRPE check acccess|
Typical Linux iptables command syntax to open GroundWork server firewall
Typically Red Hat Linux comes with only port 22 open. This command shows you the rules in place:
This command adds a rule at rule number 5 (in a typical Red Hat install there are 4 ACCEPT rules before the first REJECT rule). It says you want to allow new connections from anyone to TCP port 80 (the port used for HTTP).
iptables -I INPUT -p tcp -m state --state NEW -s 0.0.0.0/0 --dport 80 -j ACCEPT
It's important to recognize that the version of Linux you are using may not honor this alteration through reboots of your system.
