The truncate is easier to use with sudo than >. It's also easier with find -exec.

comment Disable local delivery in Sendmail
@Rodrigo example.com. with a trailing dot is a canonical FQDN. The example.com without dot is relative and thus imprecise, for example it could mean example.com.yourdomain.org. depending on your OS settings. This is exactly the same difference as between /etc/passwd and etc/passwd

comment SSL Certificate Location on UNIX/Linux
@cweiske This seems to be historical OpenSSL convention, not formally standardized, and a very unwieldy one in my opinion. My earliest trace is this version: rpm.pbone.net/index.php3/stat/4/idpl/38501/dir/redhat_other/com/…

comment How does this kind of SSL work?
@BurhanAli Popular browsers don't show the first SAN in this situation, they show Common Name (CN) field from the certificate. This is a bug on their part, a legacy behavior that is now outdated. Lets hope they start to pick up a correct SAN in the near future.

comment choosing the right SSL certificate
@TerenceJohnson I run quite a large ecommerce payment gateway with around 3k payments/day. Last month we made a decision to drop EV certs in favor of plain-old ones. As of now, not a single payer complained about this and the traffic haven't shrinked.
