Connecting from HULFT-HUB Server
HULFT-HUB Server uses TCP/IP for communication. It uses host names to identify the machines with which it communicates. Therefore, verify that connections can be established by the host name (using the 'ping' command).
Before performing the tasks described in Connectivity Test, make sure that the hosts can be accessed by using their host names in the connectivity test environment.
Examples of using the 'ping' command in HP-UX11.23 are as follows.
-
Example: Connection check results during normal operation (remote host name: uxhost1)
$ ping uxhost1 PING uxhost1: 64 byte packets 64 bytes from 172.16.52.44: icmp_seq=0. time=0. ms 64 bytes from 172.16.52.44: icmp_seq=1. time=0. ms 64 bytes from 172.16.52.44: icmp_seq=2. time=0. ms ^C ← Press Ctrl + C ----uxhost1 PING Statistics---- 3 packets transmitted, 3 packets received, 0% packet loss round-trip (ms) min/avg/max = 0/0/0 $
-
Example: Connection check results in the event of an error (remote host name: uxhost2)
$ ping uxhost2 ping: unknown host uxhost2 $
The command name or the execution results differ based on the OS or the IP version used. For more details, see the manual of each operating system.
If you are using HULFT-HUB Server for UNIX/Linux-ENT in a cluster configuration, setup and preparations for the cluster environment are required in addition to the above tasks. For details about the installation and environment setup procedures in a cluster environment, see HULFT-HUB Server Clustering Manual.
