RE: VNC v4.1.2 and XFINITY Modem

Phillip,

I want to thank you for your offer to help me. I totally understand how
things works. I went ahead to check. I noticed that VNC icon shows 10.0.0.4
and ipconfig tells me that IP address shows 10.0.0.4 and the Default Gateway
is 10.0.0.1 so, from the kitchen, I would do:

http://10.0.0.4:5800

It should work just fine.

Johnny :)

A couple of clarifications are needed:

Your modem/router has an internal address and an external address, as I
explained last time.  The whole local network shares the external address,
and the router works out who sent what for the purpose of delivering replies
from the Internet.

On the internal side, most routers take for themselves the address ending in
'1', so if your local addresses all begin 10.0.0.something, then the router
will usually have 10.0.0.1  (although there are some which take 10.0.0.254,
just to be different).  That means that the machine running the VNC server
probably isn't 10.0.0.1, because that's (probably) the address of the
router.  The router dishes out to other machines addresses on demand in that
range, usually (but not always) starting with 10.0.0.2, 10.0.0.3, etc.  So,
the address of the machine running VNC needs to be established before you
can connect to it.

To find out the IP address of the machine running the VNC server, you can
put the mouse over the VNC icon in the system tray (bottom right) and
usually a tool-tip will pop up showing the address.  Alternatively, you can
start a command window on that machine, and type:
ipconfig
... and look for a line beginning "IP Address" or "IPV4 Address".  Look for
addresses starting 10.0.0.   and you'll soon spot what you need.

Phillip,

Finally! My explanation worked out for you!!! Thank you for your lengthy
message. I totally understand now what the requirement is with the
Port-Forwardings. That is why they recommended a static IP address. You
explained why - now, I understand your description very long message. Ohh, I
got it, if I need to do a 'local' address, I should do -- I know, it is
10.0.0.1 so, it will be: http://10.0.0.1:5800 :)

I don't need to worry anything with 'public address' someone told me if I
want a static IP address from Comcast, they gonna charge me some more money.
Someone is the Network Administrator, also is on Comcast, too. Oh well. I
will just do a 'local' address for now.

Thank you very much for a good explanation.

Cheers,
Johnny :)

Ok - that's clear.

A router is a bit like a transformer.  While a transformer has high voltage
on one side, and low voltage on the other, a router has 'public' (or
'external') Internet addresses on one side (accessible from anywhere) and
'private' ('local' or 'internal') addresses on the other (accessible only
within the local network).  So when you connect from the kitchen, you need
to use the 'local' address beginning 10.0.0.whatever, and when you're in the
coffee shop or school campus, you'll need to know the 'public' address (and
have port-forwarding working).  The problem is, that your public address
usually changes from time to time (look up DHCP or Dynamic Addressing if you
want to know more about this).  When you're at home, try running ipconfig in
a command window, to see the local address that the computer has (it will
begin 10.0.0.something on your network).  Then visit the website
www.whatismyip.com, and you'll see the current public IP address.
Different!  To solve the problem of changing public addresses, you can get
your service provider to give you a fixed or static address (charges usually
apply) or you can use a dynamic dns service, like no-ip.com.  All these
things take a while to get your head around, so if you can get a
knowledgeable friend to fix it up for you then you can concentrate more on
the stuff you care about!  But I hope that's given you something to be going
on with.

If you really want to understand all this, it'll be important to get your
head around dynamic addressing.  The computers on your local network will be
issued with an address by the router, so they will all have related
addresses (probably starting 10.0.0.*  - some routers use 192.168.1.* or
192.168.0.*  - these specific address ranges are *only* used for pr

Hello, Philip!!

 

I got a good news for you!! I went to the kitchen to access my laptop via my
local Wi-Fi. I tried http://10.0.0.4:5800   and it
worked OK, however, Firefox showed nothing. I tried Internet Explorer, it
requested me to get Java since my laptop doesn't have Java yet.

 

I have a question, though.

 

My laptop is running on Windows 7. I need to know which is the best so far
my XP system uses Sun Micro System's Java that I downloaded off of
www.sun.com   . Which is the best, the Sun's or
Microsoft's Java?

 

Let me know.

 

Thanks!

 

Johnny :-)

That's great.  Well done.

I use the Sun Java, from www.java.com, but that's just through following
links that have been offered at various times.  Never had a problem.  In
Firefox, I believe Java is a separate plug-in.
