32 NetBackup Troubleshooting Guide - UNIX
7. Verify that the hosts file or its equivalent contains the NetBackup server name. On
UNIX and Windows clients, the hosts files are:
◆ %SystemRoot%\system32\drivers\etc\hosts (Windows NT/2000)
◆ C:\Windows\hosts (Windows 98 or 95)
◆ NetWare clients: SYS:etc\hosts
◆ /etc/hosts (UNIX)
8. Verify client-to-server connectability by using ping or its equivalent from the client
(step 3 verified the server-to-client connection).
9. If the client’s TCP/IP transport allows telnet and ftp from the server, try these as
additional connectivity checks.
10. For a Macintosh or NetWare client, ensure that the server is not trying to connect
when a backup or restore is already in progress on the client. Attempting more than
one job at a time on these clients, results in a “can’t connect” or similar error.
11. Use the bpclntcmd utility to verify basic client to master server communications.
When run on a NetBackup client, the -pn and -sv options initiate inquiries to the
NetBackup master server (as configured in the server list on the client). The master
server then returns information to the requesting client. For more information, see
“Using bpclntcmd” on page 35.
12. Verify that the client operating system is one of those supported by the client
software.
Verifying Host Names and Services Entries
This procedure is useful if you encounter problems with host names or network
connections and want to verify that the NetBackup configuration is correct. Several
examples follow the procedure.
Note For more information on host names, refer to Appendix B in this manual and to the
“Rules for Using Host Names in NetBackup” appendix in the NetBackup System
Administrator’s Guide.
1. Verify that the correct client and server host names are configured in NetBackup.
a. On Windows NT/2000 servers, Windows clients and NetWare nontarget clients,
check the General tab in the NetBackup Configuration dialog box and the Servers
tab in the Specify NetBackup Machines dialog box. To display these dialog boxes,
