Verifying Samba's PGP signature

According to Jerry Carter of the Samba Team, only about 22% of -all Samba downloads have had a corresponding PGP signature download (a very low percentage, which -should be considered a bad thing). Even if you're not downloading from a mirror site, verifying PGP -signatures should be a standard reflex. + The disadvantage of the unpacked trees is that they do not support automatic + merging of local changes like CVS does. rsync access is most convenient + for an initial install. +

With that said, go ahead and download the following files: -

+$  wget http://us1.samba.org/samba/ftp/samba-pubkey.asc
 

 The first file is the PGP signature for the Samba source file; the other is the Samba public
 PGP key itself. Import the public PGP key with:
-
-     $ gpg --import samba-pubkey.asc
+
+	$ gpg --import samba-pubkey.asc
 

 And verify the Samba source code integrity with:
