[BackupPC-devel] Bug Report: Perl gethostbyname return wrong value

[brian schwartz]

I think i may have found a small bug. I just started using BackupPc, and found that every time i used a host name; it did not work, but the with an IP it did work. After a few test i found the problem is with perl trying to lookup the host by gethostbuname, and that it returns true all the time. On the other hand nmblookup works fine, but is nevcer used since the program thinks gethostbyname worked.Bellow i triued to prove it ***@n00b-Server:~$ smbtree -bPassword: THE_BRUCESTER_N \\N00B-SERVER n00b-Server server (Samba, Ubuntu) \\N00B-SERVER\PDF PDF \\N00B-SERVER\print$ Printer Drivers \\N00B-SERVER\share \\N00B-SERVER\IPC$ IPC Service (n00b-Server server (Samba, Ubuntu)) \\LAPTOP Dell 5150 Laptoptimeout connecting to 208.69.32.132:445timeout connecting to 208.69.32.132:139Error connecting to 208.69.32.132 (Operation already in progress)cli_start_connection: failed to connect to LAPTOP<20> (208.69.32.132).

Bellow i triued to prove it best.

If gethostbyname() returns successfully then BackupPC believes it.
Something must be wrong with your DNS setup or perl configuration.
