Photon Management Daemon Command-line Interface (pmd-cli)
Photon OS provides the Photon Management Daemon command line interface (pmd-cli).
Setup Steps
The pmd-cli utility is included with your Photon OS distribution. To make sure that you have the latest version, you can run:
tdnf install pmd-cli
Syntax
pmd-cli [connection_auth_options] <component> <command> [command_options]
Passed-in parameter values can be enclosed in single (') or double-quotes (") as long as you use matching characters to denote the beginning and end of the value. Unless a parameter value contains special characters or spaces, you can also omit quotes altogether.
Connection / Authorization Options
Local Connections
For local connections, you omit the connection and authorization options:
pmd-cli <component> <cmd> <options>
Permissions for the currently logged-in user apply when executing commands. This is the same as specifying –servername localhost.
Remote Connections
For connecting to a remote server (a server other than the local server), you specify two connection / authorization options:
--servername: name of the server--user: username of a user account on the server
Note: For authentication, you can specify the username (–user <username>) on the command line, but never the password. For security reasons, the system must prompt you for the password.
What follows are three options for remote connections.
System User
pmd-cli --servername <server> --user <username>
Lightwave User
Before using this method, the pmd server must be joined or should be part of embedded Lightwave.
pmd-cli --servername <server> --user <username> --domain <lightwave_domain>
Kerberos spn
Before using this method, the client must run kinit successfully.
pmd-cli --servername <server> --spn <service_principal_name>
Component
<component> is one of the following values:
firewallnetpkgusr
Firewall Management
The Photon Management Daemon provides CLI commands to help you get information about the firewall.
Syntax
pmd-cli [connection_auth_options] firewall <command> [command_options]
firewall help
Get help for firewall CLI commands.
pmd-cli firewall help
firewall rules
Get a list of the current persistent firewall rules.
pmd-cli firewall rules [command-options]
This command returns information about each firewall rule, such as the chain to which it belongs, the policy to enforce, the table to manipulate, and so on.
Add a new firewall rule.
pmd-cli firewall rules --chain <chain_name> --add <rule_specification>
Example:
pmd-cli firewall rules --chain INPUT --add "-p tcp -m tcp --dport 21 -j ACCEPT"
Note: To confirm that the firewall rule was added, run iptables -S. Running pmd-cli firewall rules lists only persistent rules.
Delete a new firewall rule.
pmd-cli firewall rules --chain <chain_name> --delete <rule_specification>
Note: To confirm that the firewall rule was removed, run iptables -S. Running pmd-cli firewall rules lists only persistent rules.
Make firewall rule changes peristent (add –persist flag)
pmd-cli firewall rules --chain <chain_name> --add <rule_specification> --persist
firewall version
Get the version number of the fwmgmt component on the server.
pmd-cli firewall version
