Hi,

Was looking at the raspberrypi this morning and it brought me to the

Lots of people have answered your question. If it turns out none of

You

can have index.html have a small bit of javascript to pull up a
different website depending on the requested URL. If you use nginx,
it's even easier because you simply configure nginx.conf to do that

you: Much cleaner. I think Apache has something similar, and 20 years
ago I could tell you how to do it, but 20 years is a long time.

Also, if you're speaking of web servers, many shared hosting web
web hosts allow you multiple domain names.

and some hosting services have all that pretty much built in.  you just 
put your web server files in the right subdirectories (hint - there is 
a subdir who's name is the domain of interest), and there you go.

Thanks David!!

I have a static IP.

Last year I configured an old laptop with a private IP running LAMP + 
BIND + Postfix + Dovecot and used port forwarding.


After this discussion I'm thinking I need a router capable of routing 
multiple IPs that would replace my consumer grade router however it 
is not fully clear to me.


Thanks for your help!!
Keith

Most hosting providers share a single IP among multiple accounts
coming into a server. There are two separate IPs for DNS hosting on a
totally different server. If you want your own dedicated IP for your
account, you can usually get it. But I can’t think of any that let
you set up a separate IP for individual services unless they’re on
separate servers in different facilities. I’ve had hosting accounts
where they share a pool of IPs among hosting accounts, and I’d have
up to 6 IPs, but each account only had one IP and all of the services
used that one IP.

The only situations I’ve heard where people are using multiple IPs
is to have backup internet providers, like Cox, CenturyLink, etc, in
case one of them goes down. In those cases, you need a router designed
to handle multiple (usually two) WAN ports where one is primary and
the other is a failover.

I have a business account with Cox Cable which allows me to run 1 or

using Ubuntu, Apache, MySQL, PHP, plus Postfix and dovecot, plus
BIND.  I'm a PHP dev so I felt pretty good about that achievement.

I only have 1 public IP and everything on my network has a private
IP.  I used port forwarding to get the web server to work.

Supposedly I can get multiple IPs from Cox.  On several occasions
I've asked the level 1 how I would configure 1 or more servers on
the public IPs they can provide and they do not know how.

At some point in the future I'm thinking I'd like to create a
publicly facing group of PIs to run as a web server (or maybe
more)... 1 for HTTPS, 1 for DNS, 1 for mail, and 1 for MySQL (on a
private IP ?).

I assume I would use the Cisco gizmo that has coax in and RJ45
out... the out would go into a small switch which would route each
IP to the appropriate PI based on the BIND config.  I assume I can
plug my Netgear router into the switch that currently has multiple
devices connected to it on private IPs, and which provides WIFI.

I assume I can add a router in between the Cisco (modem?) and my
Netgear and everything would work as it does now.  The added router
would then be in place to deal with any additional IP address that
Cox would provide?

Thanks in advance for any help!!

Re: Public raspberrypi https/mail/dns... on Cox Cable

2023-07-22 Thread Keith Smith via PLUG-discuss 

Thank you to everyone who replied.

As you know I have a SOHO/business connection to COX.

Last year I configured an old laptop as a web server. It was LAMP + BIND 
+ Postfix + Dovecot.  I created two name servers on a domain with my 
static and public IP.  I then set port forwarding on my "router", and it 
worked.  Everything in my office is on a private IP.


I may never use anything more elaborate, however at some point I may 
want more than one IP, just for the fun of it, and the level 1's cannot 
tell me how to use multiple IPs.  Seems it might be as simple at getting 
a router that can deal with multiple IP addresses and plug it into the 
Cox "Modem".


Thanks!!
Keith

I dunno squat about what goes on inside of those boxes, but routers
typically have a WAN port and a bunch of “internal” ports that
are all RJ-45 plugs.

If you can get Cox to send traffic for a group of IPs to your modem,
then they should all come out the ethernet side as well, right?

Remember that their modem is NOT a “router”. You can plug a
router into it, tho.

If the public IP addresses are unchanging, you could use the techniques
I mention in my previous piece of response to direct it to the proper
IP address. And if you don't like the user seeing a bare IP address,
you can procure domain names for each IP address.

you could use a switch between cox and then use any combination of rasp
pi's and routers set to static IP's and maintain several firewalls
Intrusion protection geo blocking ect on each but a single device is easier
to maintain

others here are correct cheap consumer routers rarley have the option to
handle multiple ip's
better routers do. It is built in ipfire ( my choice of routers) on a old
computer with 2-4 network cards or in a vm also works and I think it is
available in
pfsence or opensence and DDWRT just add a alias IP and then port forward to
the server you want it togo to.

Buddy who ran cox business had 6 ip's.  stacked them on the router and
provided different SNAT/DNAT to the boxes behind.  There was some
configuration fiddliness with the modem, but this was years ago.  any
reasonable router would be able to do this, the main question is how the
modem handles it.

Re: Public raspberrypi https/mail/dns... on Cox Cable

2023-07-09 Thread David Schwartz via PLUG-discuss 
AFAIK, the Cox router can be configured to either run DHCP or as a Static IP 
address. Either way, it can only listen to one IP. They do run DHCP from the 
local hubs, but the IPs themselves rarely change, and you’re sharing them with 
the whole neighborhood.

Most hosting providers share a single IP among multiple accounts coming into a 
server. There are two separate IPs for DNS hosting on a totally different 
server. If you want your own dedicated IP for your account, you can usually get 
it. But I can’t think of any that let you set up a separate IP for individual 
services unless they’re on separate servers in different facilities. I’ve had 
hosting accounts where they share a pool of IPs among hosting accounts, and I’d 
have up to 6 IPs, but each account only had one IP and all of the services used 
that one IP.

The only situations I’ve heard where people are using multiple IPs is to have 
backup internet providers, like Cox, CenturyLink, etc, in case one of them goes 
down. In those cases, you need a router designed to handle multiple (usually 
two) WAN ports where one is primary and the other is a failover.
