To ensure the availability of port 32775, perform the following steps:

1. As the root user, use a text editor to add the following statements at the beginning of the /etc/rc.net file as follows:

   /usr/sbin/no -o tcp_sendspace=16384

   /usr/sbin/no -o tcp_recvspace=16384

   /usr/sbin/no -o tcp_keepidle=80

   /usr/sbin/no -o tcp_keepintvl=20

   /usr/sbin/no -o tcp_ephemeral_high=65535

   /usr/sbin/no -o tcp_ephemeral_low=42767

   /usr/sbin/no -o udp_ephemeral_high=65535

   /usr/sbin/no -o udp_ephemeral_low=49152

2. Save the changes and close the file.
3. Reboot the server (shutdown -Fr) for these settings to take effect.
4. Enter the following command from the command line and verify that your change took effect:

   no -a | grep ephemeral
