Checking connection with remote machine

HULFT connects to remote hosts and carries out file transfer by using the TCP/IP protocol. The remote machines that are counterparts in transfer are identified by their 'host names.'Therefore, you must verify the connection to each host by running a connection test with host name specified (using the PING command).

In addition, a local host has to satisfy all of the following conditions:

  • Active state of address '127.0.0.1' (LOOPBACK address)

  • Existence of 'Internet address: 127.0.0.1/Host name: LOOPBACK' in TCP/IP host table

In order to be ready for the communication test that will be explained later in this manual, make sure that the result of the connection test to the local host name of the machine is successful.

Note

If you are using a network in which a firewall is installed, configure in advance communication in HULFT to pass through the firewall.
