[Tech] Lock keyring in gnupg

[marcoc1@dada.it]

Ho due problemi durante l'importazione di nuove chiavi
in gpg 1.2.1.
Il keyring si trova su un disco criptato con bestcrypt.

Questo e' il file di configurazione

keyring pubring.pgp
secret-keyring secring.pgp
load-extension idea
keyserver pgpkeys.mit.edu

(uso l'estensione .pgp per compatibilita' con la 
versione windows di pgp)

[marcoc@ef98 marcoc]$ gpg --keyserver pgp.mit.edu --search-key toad@
gpg: searching for "toad@" from HKP server pgp.mit.edu
gpg: DBG: increasing temp iobuf from 8192 to 16384
Keys 1-10 of 239 for "toad@"

... e la chiave non viene importata

Se metto la directory .gnupg in locale, l'addizione funziona, ma
invece di iserire la chiave in pubring.pgp ( che e' puntato via
gpg.conf) me la mette in un file pubring.gpg che crea
ex-novo

Qualche idea? Grazie mille.   Marco
