Multiple servers with same IP but different ports - problem listing in ARD

Hi - I have no problem connecting to multiple Macs behind a single IP (router) using different ports, port forwarding, dyndns, etc., etc.
The problem I'm having is that in the list of computers in ARD, it won't let you have more than one with the same IP address. When you create the second with the same IP, it clears the first one, giving it an IP of 0.0.0.0. They are on different ports, but that's not counted as part of the IP, so it still gets cleared. I use different dyndns domain names, but ARD instantly converts them to an IP when creating the entry, so that doesn't help either.
Are there any workarounds?

And it's still impossible if they all have the same external IP. The whole stroy? See http://discussions.apple.com/thread.jspa?threadID=1321008&tstart=0
On option is to setup a VPN(=Virtual Private Network) as described in the thread I mentioned

Multiple entries in ARD with same ip, but different ports?

I always learn so much from these forums...thanks to all of you who take the time to answer.
I established 5900/3283 for my primary mac (mac 1) behind my router at home and then configured port forwarding to have a public port of 15900 mapped to the secondary machine (mac 2) at 5900. I have dyndns set up in my router and when connecting from the outside with ARD to the dns name without specifying the port, it connects to mac 1 without problem and reports mac 1 as the name in ARD. Great, no problem.
When I add the 15900 port to the dns name, ARD still shows the mac 1 as the name, but connects to mac 2. Can I fix this to correctly reflect the name of Mac 2? Also, it does not seem possible to have two clients in the ARD list with the same ip address, but different ports. Can this be fixed? Lastly, how do I connect 15900 and 13283 ports in one listing for the port forwarded mac, i.e. how do I enter xxx.xxx.xxx.xxx:15900 and xxx.xxx.xxx.xxx:13283?
Thanks,
ed

ARD won't save multiple computers with same IP and different port!

I'm trying to access multiple computers over the internet behind a firewall with port forwarding.
I can access each computer, but ARD won't save the IP address and port (in IP Address column of ARD 3.1) of multiple computers with the same IP address. It will only save ONE. I've tried 'add by address', adding a list for each computer or adding a list for all those computers. Nothing has worked. ARD will actually change the first computer's IP address to 0.0.0.0
Example: Static IP address
Computer 1 xx.xxx.xxx.xxx:51 (public port 51 is forwarded to port 5900 on computer 1)
Computer 2 xx.xxx.xxx.xxx:52 (public port 52 is forwarded to port 5900 on computer 2)
Computer 3 xx.xxx.xxx.xxx:53 (public port 53 is forwarded to port 5900 on computer 3)
Has Apple really overlooked this or am I missing something? Isn't this how most people would remotely manage multiple Macs offsite?
Thanks

ARD cannot do this as you're asking. If your
workstations get their addresses from an NAT device
rather than being "real", the ports also need to be
forwarded in the router to the workstation's internal
IP address. ARD uses port 3283 for the reporting and
updating function, so if your Macs are getting their
IP addresses through NAT, since you can only forward
a port to a single workstation, you can only get
reports, push package/files to etc. for a single
workstation.
ARD uses the VNC protocol for observation and
control, though, and there are a range of IP
addresses for that protocol, starting with 5900. ARD
uses 5900 by default, so that port would be forwarded
to the first workstation. You would, I believe, need
to install VNC servers on the systems (since the ARD
client cannot listen on any port other than 5900
while VNC servers can be set for other ports such as
5901, 5902, etc. You would then forward 5901 to the
second workstation (and on to 5902, 5903, etc.). You
can then use the following information:
Remote Desktop 2: How to specify a port number
for a VNC client
to connect.
The only other options are: 1) to run the ARD
administrator on a workstation on the network, and
then take control of that system from outside, either
via VNC or another copy of ARD, or 2) set up a
virtual private network (VPN) so that when you
connect from outside, your admin system is officially
part of the local network.
Hope this helps.
That definitely helps. I have ARD installed on my MBP and on a workstation on the LAN. I have used ARD from the MBP to control ARD on a workstation on the local network, but it can get a little tricky. I already have VNC setup on all the workstations. I used to use COTVNC prior to purchasing ARD 3.1.
I guess what I'm really asking is...
How do I add a list of workstations and save the settings (same IP address for each workstation with different ports?) to control/VNC via ARD?
I simply want a list that shows each workstation, so I can control/VNC them using ARD offsite.
Name: Computer 1 IP Address: 123.123.123.123:5901
Name: Computer 2 IP Address: 123.123.123.123:5902
Name: Computer 3 IP Address: 123.123.123.123:5903
I don't want to have to manually type in the IP address into ARD every time.
Will ARD simply not add another computer to the list if it has the same IP address but different port number as a computer already on the list? I haven't been able to find a way to make ARD do this.

Manage site with same IP but different port

My computer was updated from Windows XP to Windows 7 and I'm still using CS6. I can not manage two different sites with the same IP address but one has a different port number.
I have it set on Docuemnt Root but apparently it doesn't matter because I'm having the same issue if I change it to site root.
This is what I get to preview:
file:///B:/Admin/facility-management-leasing/facility-management/forms.shtml instead of
http://168.40.15.60:81/Admin/facility-management-leasing/facility-management/forms.shtml
I have the same IP address with out a port to another location
I'm getting file:///W:/news/Announcements.html instead of http://168.40.15.60//news/Announcements.html
Please help this is past frustrating!!!!!

Using multiple SSIDs with same name but different PSKs

I have a central WLC 2504 controller that is being used for remote site FlexConnect 1141 APs. They all advertise three different SSIDs. One SSID is a global SSID that is the same at every office. One is a hidden SSID using 802.1x machine auth.
The one I am trying to get working is the local office guest network. These SSIDs are all the same at each office but should have different PSKs. They are local to the office, therefore would only ever be applied to a specific FlexConnect group.
I understand why in theory this is generally not a good idea but given these are for remote sites I'd like it to be possible. I always get this message though:
"WLAN with duplicate SSID and L2 security policy found"
Is there a way around this? New WLC code that allows it maybe?

I was able to configure three (more I think possible) WLANs with same SSID name and all are WPA2-AES-PSK on the same WLC and all are enabled at hte same time.
Note that you can not have any of those broadcasting on same AP group. Each WLAN can be only broadcasted on a separate AP group. For your sites, It will probably need you to define an AP group for each site to broadcast different WLANs on different sites.
You can do that if all your WLANs have an ID of 17 or higher. (the reason is, WLANs of 1-16 are by default broadcasted on the default AP group. and because those can not be on the same AP group - including the default one - then you can't have them with WLAN IDs 1-16. i.e on same - default - AP group)

Multiple Devices with Same ID but Different Contacts

My family and I all use one apple id on one computer. I have 5 kids so they all wish to share music and such on their multiple devices.
But, they wish to keep their contacts separate.
Is there an easy way to do this?
I have heard of having several iClouds, but I wish to not do this if possible.
Thanks!

If you are comfortable still using the same AppleID, you can always purchase more storage at a very low cost. Just go to settings>icloud>storage & backup>and change storage plan. You can upgrade for as little as $10. Hope this helps!

Mounting multiple directories with same name on different severs to a single mount point on another server

We have a requirement where in we have multiple solaris servers and each solaris server has a directory with the same name.
The files in these directories will be different.
These same name directories on multiple severs has to be mounted to a single directory on another sever.
We are planning to use NFS, but it seems we can not mount multiple directories with same name on different severs to a single mount point using NFS, and we need to create multiple mount points.
Is there any way we can achieve this so that all the directories can be mounted to a single mount point?

You can try to mount all these mount points via NFS in one additional server and then export this new tree again via NFS to all your servers.
No sure if this works. If this works, then you will have in this case just an additional level in the tree.

Two methods with same name but different return type?

Can I have two methods with same name but different return type in Java? I used to do this in C++ (method overloading or function overloading)
Here is my code:
import java.io.*;
public class Test{
public static void main(String ar[]){
try{
//I give an invalid file name to throw IO error.
File file = new File("c:/invalid file name becasue of spaces");
FileWriter writer = new FileWriter(file ,true);
writer.write("Test");
writer.close();
} catch (IOException IOe){
     System.out.println("Failure");
//call first method - displays stack trace on screen
     showerr(NPe);
//call second method - returns stack trace as string
        String msg = showerr(NPe);
        System.out.println(msg);
} // end of main
public static void showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     String stackTrace = sw.toString();
     System.out.println("Null Ptr\n" + stackTrace );
}//end of first showerr
public static String showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     return sw.toString();
}//end of second showerr
} // end of class
[\code]

Overloading is when you have multiple methods that have the same name and the same return type but take different parameters. See example
public class Overloader {
     public String buildError(Exception e){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( e.getClass().getName() )
               .append( " : " )
               .append( e.getMessage() ) ;
          return buffer.toString() ;
     public String buildError(String msg){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( msg ) ;
          return buffer.toString() ;
     public String buildErrors(int errCount){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( "There have been " )
               .append( errCount )
               .append( " errors encountered.") ;
          return buffer.toString() ;
}Make sense ???

To create multiple files with same content but with different names

Hi SapAll.
here i have got a tricky situation on Idoc to File Scenario.
in my interface of an Idoc to file ,there is requirement to create multiple files with different file names but with same content based on one Idoc Segment.
which means there will be one Zsegment with two fields in the idoc,where one field with (content refers to the name which file name should start with .so lets say if this segment is repeated for 3 times then PI should create 3 files in the same directory with same content but with different file names (from the filed).
so here for now iam using one reciever file communication channel.
can any body give me the quick answer.
regards.
Varma

What do you mean by different names?
when i make proper setting in the Receiver Channel....on how to create the filename (what to append) like add Timestamp, counter, date, messageid.....even in this case you will ahve file with different names and that too from same File channel.
You can perform multi-mapping in XI/ PI and then your File channel will place the files in the target folder with relevant names. You cannot use Dynamic Configuration with Multi-Mapping!
If you intend to use different File channels, then do the configuration as required (normal)...even over here you can follow multi-mapping.
Do not use a BPM!

Abhishek.

Importing files with same name but different extensions

Hope I will be clear enough.
Lets say that instead of sending a file from Lightroom to an external editor, I open it directly in Photoshop.
When I'm done, I save the edited photo using the same name but in a different file format : IMG_1333.cr2 > IMG_1333.psd or IMG_1333.tif, and selecting the same folder location.
Then, I come back into Lightroom and synchronise the folder.
Why is the knew version of the picture not showing up beside the original file, despite the different extension ?
I notice that the different extensions ( .psd or .tif ) are recorded in the sidecar files field in the Metadata panel.
Of course, everything works fine if the file name is modified ( or just by selecting the "copy" option in Photoshop's "save as" dialog box ). Lightroom synchronise dialog shows the new photo to import.
So, why is Lightroom not making a difference between files with the same name but different format extensions ?
Thanks for any hint :-)
Gilles.

Gilles-
I think your problem is likely that you have the option to stack the copy with the original turned on. First, right-click on one of these photos and go to the stacking menu. If Unstack is not grayed out then you have a stack -- select Unstack to reveal all copies.
To change the automatic stacking of edited copies from Photoshop, when you next choose to edit a file, in the bottom left corner of the dialog is the check box for unstacking. Clear it, and that choice should "stick" until you change it again.
Hope this helps!

Three types of restaurant menus with same dishes but different prices.

Hi,
I have to artwork three types of menus for a small restaurant chain. These menus have the same dishes and same background but different prices per restaurant. I will be sending three high res PDFs to print and would like to know if there is a way of doing this without creating three versions of the menues. I know I could create layers and have a layer per restaurant with the text boxes on, turning off and on as I create my PDFs for print but can I have text within the text block that I can turn on and off? Two text blocks, one with prices and one without, is not an option becaues the text all needs to run round together. The reason for this is if a dish needs to be amended it only has to be done once to the master dish. I hope this makes sense.
Many thanks!

Hi Guys,
Thanks very much for your speedy responces!
With regard to the data merge method I am not sure this would work for me because there is a lot of text and I need them to flow from page to page so would need all the text and prices in one text block (I hope I have understood your method correctly MW Design!). I have just had a look at the Conditional Text method and that seems as though it might work for me but one issue I might have is if one dish is removed form a menu all together then the text will run up from another block. I am sure there is a way once I have the master menu done to force the text to the next text block after the last dish I want on that page and then enlarge the text block a little to accommodate any movement of the dishes on that page, I will look into that!
Thanks very much for your help.
PS InDesign never ceases to amaze me!!

WRT160Nv2-Problem with Single Port forward to multiple servers with same internal port numbers.

On my network I have 3 systems that I've set up as RDP hosts. And need to get to all three of them externally. So I'm trying to do the following single port forwarding.
RDP 1   Forward 4000 to port 3389 for 192.168.1.11
RDP 2   Forward 4001 to port 3389 for 192.168.1.12
RDP 3   Forward 4002 to port 3389 for 192.168.1.14
When I hit "Save Changes" I get the error "Port range already exists". So it's good that it won't let me overlap ports generally, but at the same time, I'm trying to send them to different IP address. There should be no overlap in this case. Please advise
I'm trying this on the WRT160Nv2 with firmware 2.0.02, which I had just bought this weekend.

kevj,
Thanks for your suggestion. I have now upgraded the firmware to 2.0.03 build 7. But I am still seeing the error message
As I mentioned previously, I'm trying to single port forward to multiple machines in the following way:
Machine 1:   Forward 4000 to port 3389 for 192.168.1.11
Machine 2:   Forward 4001 to port 3389 for 192.168.1.12
Machine 3:   Forward 4002 to port 3389 for 192.168.1.14
The error appears to be generated by the fact that 3389 is selected for multiple external port numbers, but the same internal port number. The router I believe isn't taking into account that the similar internal port numbers aren't taking into account the different internal ip address I'm trying to send this to.
This would be a standard sort of practice for running a live HTTP server on one machine, and a new beta HTTP server behind the router on a secondary machine on the same internal port, but different external port numbers for test purposes from the outside.
Please advise
Thank you.

Is it OK to have two SBS Servers with same name, on different subnets but connected over a VPN?

Hi Everyone,
I'm just about to connect up two SBS 2011 Servers with the same server name but on different subnets & domains over a VPN.
So for example both servers will have the name Server01, one would have an ip address of 192.168.85.5, the other 192.168.86.5, they both then would be connected over a VPN.
Can anyone foresee any issues with this configuration, like DNS & DHCP requests, adding new machines to the domain, mapping drives etc.
Many thanks,
Nick

Hi Larry & Strike First,
Thank you for your responses. I understand that this is an unusual situation. Basically I've recently taken over the IT support for this client. The client has just had a new phone system installed
& are asking if they can speak to each office internally, which can easily be done once I setup the VPN.
However I noticed whilst looking at this further that the Server names are the same, hence my question?
Am I right in saying that providing the workstations have a trust relationship with their own domain controllers through their individual domains on separate subnets, that hopefully there shouldn't be any DNS issues between the two domains and Servers?
I could build a new VM if you feel it would be better practice to do so?
Many thanks for your assistance,
Nick

Multiple Servers with same Remote Interface?

Is it possible to declare the same remote interface on multiple RMI servers? Secondly, is it possible to pick which RMI server will manage a particular request?
In other words, imagine if multiple servers could service a particular request that has the same signature, but the client wants to specify which server to send the invocation. An example would be the following:
public String getPhoneNumber(String pLastName) ;But the client should decide that server A should manage requests of last names starting with A-G, server B should handle H-P, and server C should handle Q-Z. The remote method invocation is the same, but the server upon which is should be invoked needs to be determined at runtime.
I realize this can be done multiple ways, with an interim proxy server that designates the server. However, I'm most interested in the ability within the RMI and/or JNDI standard to select and invoke methods on a particular server.
Thanks for any help.

"Server" is a little bit vague in this context.
My assumption is that you want separate RMI servers running on separate hosts. (Otherwise, why bother with multiple "servers"?)
That being said, it's not clear to me how you would expect RMI to sort out something as application-specific as you suggest. It sounds to me like you need your own registry/redirector. This is going to either be an rmiregistry rewrite by you, or - as was suggested by another poster - a proxy.

Is it possible to install two SAP system with same SID but different instance numbers on one host?

Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?
If yes, then how?
If no, then why?
Thanks in advance.

Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?
Yes, it is possible. If one is CI (PAS) and the second one is an AS (AAS). In this case there will be only one database.
If you are talking about two separate SAP systems with separate databases (Eg: A BI and an ECC) with the same SID then the problem will be with the database (Eg: Oracle)
The database will be installed under /oracle/SID/112_64 (ORACLE_HOME) unless one database is running on 10 G and in that case the ORACLE_HOME will be /oracle/SID/102_64
The next issue will be with the SAP file systems like /sapmnt/SID
The most important problem will be with the switch to the sidadm and orasid users and the conflicts there. If there is a need to stop one of the SAP systems and if you do a switch to sidadm and issue a stopsap command which system will be stopped ?
These are few of the many problems I can think of.
So if we are talking about two separate systems with their own databases I would rule out the possibility of having two systems with the same SID.
