:Hello people, i hope you can enlaight me a little.
:I installed my DFBSD, configured it, instelled a lot of services
:(apache22, sendmail, imap, dns, pop3, webmail, php4, php5, perl, some

:line between them, and what each of them means.
:Can u please point me to some place with a nice explanation? I am
:googling it but only find some technical stuff about them and no the
:Thanks for any help
In almost all cases you set your machine's hostname to your fully
qualified domain name. So for example if your domain is 'mydomain.com'
and you want to name your machine 'mymachine', then the fully qualified
domain name for your machine would be 'mymachine.mydomain.com' and you
would put this line in your /etc/rc.conf:
Many BSD's have a utility called 'hostname' which can be used to
set the hostname manually but usually you do it by specifying it in
/etc/rc.conf and the boot sequence will set the name.
Many BSD's also have a utility called 'domainname'. This utility
is only used for an obscure protocol called NIS and should not be
used. It can cause confusion, though. Just don't use it.
When you set up your DNS resolver you can specify shortcuts. For
example, all of my <blah>.dragonflybsd.org machines have an
/etc/resolv.conf that specifies this line:
You would have a line like this:
What this line does is allow you to shortcut the name you use to
access your machine. That is, you can just go 'ping mymachine'
instead of having to say 'ping mymachine.mydomain.com'.
