Managing Sun RPC Services
Use the Sun RPC services table to control Sun RPC traffic through the security appliance based on established Sun RPC sessions. To create entries in the Sun RPC services table, use the sunrpc-server command in global configuration mode:
hostname(config)# sunrpc-server interface_name ip_address mask service service_type protocol {tcp | udp} port[-port] timeout hh:mm:ss
You can use this command to specify the timeout after which the pinhole that was opened by Sun RPC application inspection will be closed. For example, to create a timeout of 30 minutes to the Sun RPC server with the IP address 192.168.100.2, enter the following command:
hostname(config)# sunrpc-server inside 192.168.100.2 255.255.255.255 service 100003 protocol tcp 111 timeout 00:30:00
This command specifies that the pinhole that was opened by Sun RPC application inspection will be closed after 30 minutes. In this example, the Sun RPC server is on the inside interface using TCP port 111. You can also specify UDP, a different port number, or a range of ports. To specify a range of ports, separate the starting and ending port numbers in the range with a hyphen (for example, 111-113).
The service type identifies the mapping between a specific service type and the port number used for the service. To determine the service type, which in this example is 100003, use the sunrpcinfo command at the UNIX or Linux command line on the Sun RPC server machine.
To clear the Sun RPC configuration, enter the following command.
hostname(config)# clear configure sunrpc-server
This removes the configuration performed using the sunrpc-server command. The sunrpc-server command allows pinholes to be created with a specified timeout.
To clear the active Sun RPC services, enter the following command:
hostname(config)# clear sunrpc-server active
This clears the pinholes that are opened by Sun RPC application inspection for specific services, such as NFS or NIS.
