Description of Problem:
samba should recognize /yy parameters as network mask.

Version-Release number of selected component (if applicable):
samba-2.2.3a-6

How Reproducible:
Change a working smb.conf "hosts allow" directive to the xxx.xxx.xxx.xxx/yy 
format, and run smbclient -L BIGSERVER (locally, from BIGSERVER).

Works ok with: "hosts allow = 192.168.0.0/255.255.255.0 127.0.0.0/255.0.0.0"
... but not with: "hosts allow = 192.168.0.0/24 127.0.0.0/8"

I mark this as an enhancement because, although "man smb.conf" says that it 
recognizes ip/mask pairs, the example is written as "150.203.15.0/255.255.255.0"

Depending on the smb.conf configuration, you may get a "Not listening for 
calling name" or simply a "Connection failed".
