Disable dns lookups for mysql

In a small environment VPS or VDS, there’s very little reason to rely on DNS resolution inside MySQL.
You can disable it by adding ‘skip-name-resolve’ to your my.cnf (section mysqld) or by using the ‘–skip-name-resolve’ command line argument. Remember: If you disable DNS lookups, you will need to set permissions using IP addresses rather than host names!

Noninteractive package installation on Debian squeezy – debconf way

Once you have many Debian servers, maintenance would be a problem. Sometimes, I would like to install Debian package in all of these servers. However, it takes too much time to ssh into every hosts, and answer the installation questions one by one.

Thanks for the debconf(1), it’s quite easy to do non-interactive installation, since debconf already provide a noninteractive frontend. All you need to do is set the configuration before you install the package. It can be done by debconf-set-selections.

smtpd_sasl_auth_enable = yes
smtpd_sasl_authenticated_header = no
smtpd_sasl_exceptions_networks =
smtpd_sasl_local_domain =
smtpd_sasl_path = 
smtpd_sasl_security_options = noanonymous, noplaintext
smtpd_sasl_tls_security_options = noanonymous, noplaintext
smtpd_sasl_type = cyrus

    smtpd_sasl_type = dovecot | cyrus
    smtpd_sasl_path = private/auth

This example uses a pathname relative to the Postfix queue directory, so that
it will work whether or not the Postfix SMTP server runs chrooted.Regardless of the
SASL implementation type, enabling SMTP authentication in the Postfix SMTP server
always requires setting the smtpd_sasl_auth_enable option:
