Can I open a port range in the firewall for one host?

Can I open a port range in the firewall for one host? In other words, I want to be able to open ports 54001 to 54050 to allow one remote host in my LAN to access that port range in my Mac Server. Is this possible? Currently, the only option I see is to open individual ports for all external hosts (eg http or https)
Thanks in advance!

Which version of OS X Server are you using?
Server 2.2 and earlier includes an interface to a software firewall that can be configured to open specific ports very easily. Descriptions of how to configure the firewall can be found in the documentation for these versions.
Server 3.x no longer has an interface to the software firewall - it is still there, but you need to use other methods do configure it. A popular example of such a method is the icefloor utility.
Apple suggest that for Server 3 you delegate firewall duties to an external router. Server 3 includes the ability to configure the firewall component of Apple Airport routers 'automatically'
if you connect a machine running Server 3 directly to an Airport Router the router appears in the LH pane in the Server.app window (usually second line, below the entry for the server itself), and you can control what services are 'enabled' through the firewall there.
a more common solution perhaps is to use a non-apple router, and configure the firewall (and so open specific ports) through whatever control interface is provided for that router. There are many many kinds of hardware router you could use, and the control interfaces used vary widely - so you will have to consulting the documentation for your own router to work out how to do this.
If you post information about your software versions, and hardware configuration, it is possible that you can get more specific help with the tasks involved in opening the ports.
Hope this helps.

What port-range in the firewall of a Socks (e.g. JSocks) server?

Hi there,
I am using the JSocks implementation of a socks v5 server.
Some of my questsions are quite general (not only specific to JSocks) and I hope that someone knows the answer. Unfortunately the forum of JSocks (sourceforge) is only rudymentary so I think this place is better to answer my questions.
However...
As I understand the socks proxy, the server waits on a specific port - normally 1080 and processes the client requests (bind, connect, accept...).
For example one client requests a bind. Then the socks server opens a port locally on the socks host and (if successful) replies the new listening port and ip to the requesting client. ...
(Forget authentication, cascaded proxies and ip-ranges at this point!)
Now, if other clients should be able to access this port, the firewall (if any) needs to allow connection to this port.
My questions:
What should be an adequate port range for the socks proxy? With other words: what is the port range of the new ports that are created for the requesting clients?
How schould a seperate firewall be configured not to conflict with a socks proxy?
Specific to JSocks (if somebody knows this he wins a virtual cookie): What is the port range that JSocks uses if it opens (generates) new ports for its clients?
Where is the port range defined in the jsocks - I havent found any?
Imagine that on the same machine there are other running applications that are listening on predefined ports. (e.g. 8080, 21, ...) - what is the best way to exclude the ports in jsocks?
Any hints and explanations are welcome!
Edited by: krafzig on Oct 28, 2008 8:27 AM

You only need one port.OK, initially I need only - lets say port 1080.
But then for example a client c1 requests a bind. The socks server opens a new socket for the client (e.g. on 50000) and tells the client on which port on the socks he is now listening, right?
In order to allow client c2 to connect to this new port the firewall needs to allow access to the new port (50000) first.
So there are more ports - there might be hundrets or thousands, right?
If its on a seperate box it doesn't matter. If its on the same box it should manage different ports.yes, different ports!
However, it should allow access to the ports that the socks opens for the clients, right?
Optimal would be a dynamic adaptation of the firewall, whenever the socks opens a new port the firewall grants access.
I assume its configurable, so its up to you.No, unfortunately it is not configurable. At least I havent found anything.
Probably won't either.???
Don't use ports already used. `netstat -a` will list all the used port on that box. obviously, and Jsocks allows to configure reusage of ports by flag true/false;
Has anybody setup a socks proxy with a firewall and knows how this is/should be done normally?
Has anybody experiences with JSocks?

How disable the firewall for only one NIC (aka adapter)

Hi people,
in winXP it was super easy to disable the firewall for one specific "adapter"
(just to need to uncheck)
so in Win7 how we disable firewall for one adapter ?
thx people :D

I have found it :D

Tecra M1 - Modem doesn't work (can't open a port)

I have a problem: After reinstalling WinXP and drivers on my Tecra M1, modem doesn't function. It even can't diagnose itself - there always comes a warning: "Can't open a port (COM). It may be used by another device or application". I installed the latest Toshiba drivers for the modem, but nothing changes. How can I fix it? Looking forward for your advices!
Best regards.

Hi
Did you install the drivers in the right order? Not? So do it!
Did you install any additional devices or software which could has a bad influence on the modem?
Check the modem status in the device manger. Can you see any yellow exclamation marks?
Try to start the modem test within the Operating system.
Check the Modem function under
Start -> Control Panel -> Phone and Modem Options -> Modems Tab -> Properties -> Diagnostics
by pressing the "Query Modem" button.
If the Modem Information window contain a list of AT commands (including ATI2, ATI3, ATI4 etc.), then the modem is correctly installed. The ATI5 command ends in with the number for the selected Regional settings (for example Germany = 06).
To change the Regional Setting please use the Toshiba Internal Modem Region Select Utility.

Can't open local port

Hello all
I would be very grateful for some help with this problem,I haven;t been able so solve and i have spend a lot of time on it
I have written my own client RTSP code,from this i can set the client ports i want to recieve and send RTCP and recieve RTP,and can read in the server ports
So i have something like 157.190.181.36 60972 60973 client
157.190.181.36 6972 6973 server
To handle RTP i have used RTP socket player or RX and may other RTP reciver options,as in the java solutions etc ,so that i can recieve RTP and create a player
When i run them i get the same eror from all error can't open local port
Further information
I am on a LAN,but hav tried my set up disconnected from the LAN through a hub set up
I have tried opening the ports before callled the RTP players i.e
on the client side
DatagramSocket RTPsocket3= new DatagramSocket(60972);
DatagramSocket RTPsocket4= new DatagramSocket(60973);
Through sniffers
I know the RTSP messages are OK
I recive an ICMP message destination unreachable
I am connecting to darwin streaming server and i can connect to this and play through apple quicktime player or JM studioTHANKS IN ADVANCE!

Hey...
I'm having a similar problem, because i'm developing an application that its serving RTP audio context streams. So the application would transmit a playlist of files over RTP, and it works fine for one file, but when i try to give it a new file, i always get the exception "Can�t open door: ...". This error occurs on the line that is marked with *****.
I'm creating a processor for each file i want to transmit, for the same port and same IP address, so when the first file ends i close the processor and create a new one with the same properties, but with a diferent file...
I really nead this to work, so if someone could help me on this it would be really appreciated... Thanks in advance...

Firefox can't open normally without going through the "this is embarrassing" routine; nor does it close down properly; it also sticks frequently, i.e. screen freezes for a minute or more; should I uninstall and re-install to try and debug?

Firefox can't open normally without going through the "this is embarrassing" routine; nor does it close down properly; I get the "end program" message and have to say "end now"it also sticks frequently, i.e. screen freezes for a minute or more; should I uninstall and re-install to try and debug?
- I've used Firefox exclusively for around 2 years.
- My outlook express has no problems
- other programs seem unaffected; it seems peculiar to Firefox.
- my main use is surfing the net, primarily entering competitions on line via specialist competition sites.
- every day at some stage(s) I have to switch computer off as Firefox has got very slow/sticky/freezes.
I'm not techy by any means, but I can only thing of un- and re-installing to hopefully start with a clean slate.

Sounds like something is keeping Firefox from closing properly. See this: <br />

How can I show a 0% range in the data value label on a bar chart thanks?

How can I show a 0% range in the data value label on a bar chart thanks?

I'm not sure what the question is.
I know that if you have a bar chart and one of the categories (X-axis) has bar (Y value) equal to 0%, no bar is plotted for that category. Even the addition of a stroke (line) around the bars doesn't make one appear for 0%. The only automatic way I know of to make it look like there is data in that category is to add the value labels to the bars. Inspector/Chart/Series, select one of the bars on the chart, click on "value labels". Another method that is a workaround is to fudge the number a little in your table so that instead of 0% it is a very small %. This will get you a thin line on the chart.
But if your question is about the value labels (the numbers that display on or in the bars) and you are not getting one for a bar that is supposed to be 0%, it probably means your table doesn't actually have a 0% in the corresponding cell. A blank cell in the table will not get a value label.
