RedHat Linux 5 NetBackup client backups fail with a NetBackup Status Code 57 (client connection refused).
client connection refused
Run the following Linux RedHat command to verify that the xinetd package is installed:
rpm -qa | grep xinetd
If installed the output will look similar to:
If there is no output generated the xinetd package needs to be obtained from RedHat and installed on this client.
If the xinetd package is installed and the client is failing with a NetBackup Status Code 57 (client connection refused), check that xinetd is running by executing the following command:
ps -ef | grep xinetd
If running, the output looks similar to:
root 5040 1 0 11:41 ? 00:00:00 xinetd -stayalive -pidfile /var/run/xinetd.pid
If xinetd is installed and not running, the Redhat operating system will need to be configured so that xinetd is started each time the system boots.
Once xinetd is installed and running, the following commands can be used to verify that vnetd and bpcd are listening:
netstat -a | grep bpcd
netstat -a | grep vnetd
The output from these commands should show the following outputs, respectively:
# netstat -a | grep bpcd
tcp 0 0 *:bpcd *:* LISTEN
# netstat -a | grep vnetd
tcp 0 0 *:vnetd *:* LISTEN
If bpcd and vnetd are in a listen state and backups continue to fail, additional troubleshooting needs to be performed and may require contacting NetBackup support.
Additional items to check:
Run the following command to verify the correct client binaries are installed:
Compare the output from this command to the required NetBackup client binaries as indicated in VERITAS 6.x NetBackup (tm) Operating System Compatibility List (refer to the related documents below).
Run the following command to determine if iptables firewall rules might be blocking connectivity:
