As a rule, only use /etc/hosts for hosts that cannot be resolved by DNS (i.e.: local network) or NFS hosts that provide critical filesystems (because the resolver might not be reachable at /etc/rc.d/mountcritremote time). -- Mel Problem with today's modular software: they start with the modules and never get to the software part. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

You would also have to deal with the name server issues to get the web stuff (ports 80 and 443) directed to your single IP. If you do the name service, that is easy. If you have to beg another service, then that could be the hardest part. jerry Oh and for reference, I am not talking about web redirects. _ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: DNS and IP
Of course, just setup a virtual host in your httpd.conf file point the dns to the same ip. Apache will take care of the rest.

Re: DNS and IP
Hi, Of course, just setup a virtual host in your httpd.conf file point the dns to the same ip. Apache will take care of the rest. To be a litthe bit more precise, in your Apache configuraton you need something like: NameVirtualHost 10.0.0.1 VirtualHost 10.0.0.1 ServerName www.first-server.com ... /VirtualHost VirtualHost 10.0.0.1 ServerName www.second-server.com ... /VirtualHost BUT you will not be able to configure SSL on both sites, it will be either one or the other. You need on distinct IP per site to configure SSL.

Hi Brian,
to be more generic in the answer, you can map as many FQDN (fully qualified
domain name) as you want to a single IP via DNS (you can even enable wildcard
records in certain DNS server software that will match *.yourdomain.com to a
default IP).
That tells {client_software} that {this_FQDN} is {this_IP}.
{client_software}will use that information in whatever form is suitable to
{client_software} - in most cases it will contact {server_sofware} running in a
server (or group of servers) running as {this_IP}. It is up to
{server_software} to determine how the request from {client_software} is
handled.
For a variety of {server_software}, there is support for named based virtual
hosts, where the server will behave differently depending on what FQDN the
client is attempting to contact : web servers, FTP servers, etc. Others don't,
because it doesn't make sense, or because the protocol used doesn't support
such thing (HTTPS, for example).
If you want a more specific answer, you need to defined what you want to do.
Odds are, you are talking about websites - the other replies to your mail
should have answered that point.
Best,
B

To be even more specific: the domain name of the recipient is
specified at ISO-OSI level 7 in the HTTP protocol with a Host:
header like this:
Host: www.example.com
This header, alongside other HTTP headers is received on port 80
of your web server, and it's up to your web server to route that
to the right virtual domain by serving the correct files...
By the way, if you're using Lighty (lighttpd), you can host
virtual domains as well:
