sending mail on lan...

[Jerry LeVan]

hi all,

I misspoke yesterday when I said my fedora box used a caching  
nameserver...

What it does do is use a control file nsswitch.conf which can be used
to give a lookup order for the c library when looking up (among other  
things)
host to ip-addresses translations.

An entry in this file that controls dns looks like

hosts:	file dns

This tells the C library to check /etc/hosts before trying dns
which is why (I think) that smtp can send mail to the other
hosts on my lan...

I don't think that the lib C on Mac has this capability...
