Backup failure with error code 48

Hi, I am having a trouble with backup of few Linux clients as they are failing with error code 48. 

Ping, bptestbpcd is perfectly fine. 

In Host properties>>Clients>>client name(Check to make sure that configuration is set to access the server).

    Hello,

     

    This usually relates to name resolution, forward and reverse.

     

    Make sure you can do nslookup of the IP address and the name, and also that bpclntcmd -hn /-ip work correctly.

     

    Then finally, if you've just added the dns entries or hosts file entries, run

    bpclntcmd -clear_host_cache on master, media, and client.

    This may relate to Netbackup client using reverse DNS lookup (get host by IP address). This can be disabled on the client by running:

    bpclntcmd -reverse_name_lookup prohibited

    Thanks to all. Issue was due to host file missing entry that was done and issue was fixed. Thats why issue was related to name resolution else connectivity among client and server was OK. Thankyou !!
