Prefer DNS name to last known IP

One of the most annoying behaviors of ARD is that is seems to care only about the IP of the client. I frequently lose connections to clients in our DHCP environment when the IP changes. ARD already knows the DNS name of the client, but it does not seem to even try to do a DNS lookup to try to reconnect when the IP changes. Does anyone know of a hack or other method to have ARD do a DNS lookup when it cannot contact a client?
Thanks!

Get Info on the client. Edit the info. Delete the IP address. You may, or may not, need to make an edit of some sort in the DNS field (so it registers a change). Save the new info.
This should force ARD to prefer the DNS name over the IP address.

Updating DNS Names

Hi Everyone - first post, so please bear with me whilst I learn the ettiquette here
I administer a classroom of about 30 macs (mainly G4 eMacs with about 10 power macs) for a postgraduate newspaper journalism class. We recently (last summer) decided to try to implement a more comprehensive management/imaging scheme for them, and bought apple remote desktop and a copy of Tiger Server.
The problem I'm currently having is updating the DNS name information in the Apple Remote Desktop application (server side). I've had all of the dns records for the machines updated to something human readable so that dns information can be used as part of an automatic renaming process on newly imaged machines. But ARD still displays the old names.
I've tried refreshing the dns cache on the server on which they're stored, as well as removing machines and re-adding them by IP address. Reverse DNS lookups (which is the method apple says ARD uses to set the DNS name when computers are added) work in any other context. But ARD still remembers the old, out of date DNS information.
Does anyone have any pointers as to what's going on? Where is this information cached, and how can it be updated?
Thanks in advance!

Hi Brian, thanks for replying.
I didn't enter the dns details for the machines in the first place. I can edit the dns names manually, but that isn't the point. The ARD manual does state fairly clearly that the DNS names are set when the machine is added using reverse-dns lookup. This should ensure that the DNS name setting is correct, and should safeguard against typos etc.
Of course, even if I were to re-type each DNS address manually (possible for 30 odd machines, I suppose, though it wouldn't be if this were 300 odd), I'd have to do a reverse dns address for each computer address ANYway.
I suppose I could bypass the problem by writing a hybrid applescript/bash script that looked up the dns address for a given IP address and changed the dns name through ARD... but I'd prefer it if there was a way to force ARD itself to re-lookup the information so that it was correct.

This field name is not known errorKindError

Hi!
I am developing a user interface from ASP.NET/C# (.NET framework version 2.0) to allow users to view the crystal report as a PDF document. I am using ORACLE 10g parameterized Stored Procedure to retrieve the data from the database.
The report previews perfectly alright in the Crystal Report designer but fails to behave the same in ASP.NET 2.0 run time environment.
I am using Crystal Report XI Release 2 with incremental service pack 4. The Crystal DLL version in my .net solution is 11.5.3700
Also, my report has another embedded Sub Report which uses another Stored Procedure but the same parameter as in main report.
The error that I face (i.e. the field name is not known) is on the sub report and not on the main report. If I remove the sub-report from the main report design, then I have no errors.
Am I missing any hot fix for this problem or CR XI Release 2 with SP4 does not support sub report functions?
Please guide me as I am struggling with this problem from last two weeks and I am very close the production release.
Thanks for your support in advance.

My current code:
myReportDocument = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
conInfo = GetReportConnectionInfo();

foreach (CrystalDecisions.CrystalReports.Engine.Table rptTable in myReportDocument.Database.Tables)
            rptTblLogOn = new CrystalDecisions.Shared.TableLogOnInfo();
            rptTblLogOn.TableName = rptTable.Name;
            rptTblLogOn.ConnectionInfo = conInfo;

            //     db.Log_Result(rptTable.Name + " is able to Connect ? = ","",rptTable.TestConnectivity().ToString() );
myReportDocument.SetParameterValue("P_STRING_PARAM", "PARM_VALUE");
myReportDocument.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, @"C:\VS2005Projects\LetterNew.pdf");

        CrystalDecisions.Shared.ConnectionInfo retVal = null;
        retVal = new CrystalDecisions.Shared.ConnectionInfo();
        retVal.DatabaseName = "TSTDB";
        retVal.ServerName = "TSTDB";
        retVal.UserID = "TST_USER";
        retVal.Password = "TST_USER_PWD";
        return retVal;

Hi;
I don't see in your code where you are passing the stored procedure parameter to the subreport. This could be what is missing. Have a look at the samples here:
https://smpdl.sap-ag.de/~sapidp/012002523100006252712008E/csharp_web_smpl.exe
I believe one of these demonstrates passing parameters for a subreport.

Marcelo,
It is possible to have more that one external DNS name. Please see:
Array Manager - Array - <server> - General - Properties
In here you can map ip-addresses (of clients) to dns names.
However, a user will not be able to dynamically choose which server to
access - the
server will be selected on the first matching IP pattern.

DNS Name not Sharing Name

Howdy all,
I've been noticing and have been dealing with until now that the entry in the DNS Name column doesn't always report accurate.
For example
I have a laptop/desktop named Comp-Mac28-UserName in the Sharing Preferences' Computer Name Field.
ARD reports in it's Name field the same from the Sharing Prefs' as above.
However in the DNS Name, I get one of either the :
• correct name
• Unknown
• blank (as in white space and not the word blank)
• another machine's name (oddly enough, a Windows machine)
Has anyone seen, dealt with this bug, annoyance or feature?
Thanks in advance.

I believe this is due to the TTL (Time To Live) for DNS entries. We just moved over to VLans here and all the machines are grabbing new DHCP IP numbers. Because of this as new computers are moved over they are grabbing numbers of other systems that have been turned off for a while. The old DNS name still exists on that IP. Use Network Utility to see what DNS names are associated with that IP. I bet that more than one name is on that IP number.

UCS direct KVM access - CIMC ip address - DNS name

Hello community,
I have a little problem. We are using UCS 2.2(3d) and 32 B200 M3. Now I want to use KVM direct access.
For all 32 Blade Server, we have created DNS entries for their CIMC IP addresses.
example: ESXserver1.rc (servername + ".rc") <-- --> 192.168.0.1 (CIMC IP address)
If I enter the CIMC IP address in browser, KVM direct access works fine.
If I enter the DNS name in Browser, KVM direct access page loads, I log in and get the following error message:
GetKVMLaunchUrl: Invalid or zero CIMC IP Address passed
Can someone help me? Do I have to configure something?

User will get portal server access if it has portal desktop service. The only way to enable ip address conditions in Access Manager is using AM Policy Service, i. e. via policy agents.
If Portal server is installed in the same appserver domain than Access manager you won't be able to install a policy agent, that's a known issue.
If Portal server is installed in another appserver domain, perhaps you can use a policy agent, however, I'm not completely sure about it because Portal server needs AM SDK installed and Policy Agent also configure some AM clientSDK stuff... probably you will find some compatibility issues regarding such override of libraries.
Indeed, the Access manager issue that don't permit use a policy agent in the same domain where Am is installed is because some libraries are overriden and classpath loader do nasty things.
So what I could suggest you is search a bit about compatibilities and if you don't find any issue, you could test.
I don't see other way to enforce such a rule :(.

Network adaptor DNS name reverting to old

Hi guys,
We setup a OSX SL machine to test its email performance. When it was setup, the admin gave it a host name like company-mailserver.com, but we modified this and related server identity names to reflect the new email domain it would be handling, mail.diffcompany.com; and since then its running mail services and server configuration get screwed up constantly.
When it was working last week, changeip -checkhostname showed proper hostname and DNS hostname matching for mail.diffcompany.com, and the DNS name as listed in the server administrators panel (under network) showed mail.diffcompany.com for the en0 ethernet adaptor. But when I came in to work today, the machine's thinking wheel was spinning in the server admin panel, and numerous other fields that were filled in correctly and working for mail, dns, etc reverted to default blank.
I saw this before and immediately checked the ethernet adaptor DNS name, and sure enough it had reverted to company-mailserver.com. Why does this keep happening? I have noticed that other services that were originally setup were using the company-mailserver.com name, so clearly there's some sort of legacy/cache going on of the first DNS entries that I cannot seem to undo. Nonetheless I disabled all those other services so I would assume they shouldn't have any effect.
Other posts I've read suggest that once DNS records get screwey, often you're better off reinstalling the whole shebang. I'd like to avoid that at all costs, as this would not be viable in the the future, and I'd like to know what exactly is going on anyway.
Anyone have this experience? What steps did you take to fix it?

I'll assume the box is not using DHCP for its IP addressing. If the box is using DHCP for its network controllers, switch over to a static address and static-defined DNS references.
Given the fundamental nature of DNS in a modern IP network, if you're going to, um, misrepresent the configuration to the server and to DNS, then, um, Bad Things can happen if you don't correctly and entirely, um, misrepresent DNS and the configuration.
if you want to do this such that it'll be stable, then set up your own local DNS services on the box and aim the box at its own DNS and aim the DNS server at your forwarding servers, and effectively create your own little private bubble of example.net within your enveloping example.com network configuration.
[Here's a local DNS set-up|http://labs.hoffmanlabs.com/node/1436] that would likely work here. You'll have a zone for your example.net target domain for this server (its own "bubble"), and set up your forwarding or such to aim at your (other) local DNS servers, and those can then reach out to the rest of the Internet.

Communicate with cRIO when IP Address and DNS Name changes over Network Variables

I am developing a LabVIEW software for an European Project using cRIO-9074 and RT Application Reployment to update all cRIO devices with the last version.
To communicate with the cRIO devices I have also developed some applications that are outside cRIO on LabVIEW Project that uses Network Variables to Read/Write to the devices.
When I am developing the software, everything works just fine because the LabVIEW Project knows the IP Address on my cRIO device. However, when I use RTAD to install the software and then my applications outside the LabVIEW Project, the aplications are, not always able to find the device when the IP address changes.
I have tried to replace the IP Address with the DNS Name but no success. When I change the router that is connected to the cRIO, the DNS Name also changes.
With this, my question is how can I solve this sistematic problem? Should I change any configuration on MAX, in LabVIEW Project and/or in the applications to be able to always find the cRIO? Is it possible to have a field on the application to insert the IP Address of the device to connect? If yes, how can I do this?
Best regards,

Quintino,
You can programatically open connecitons to Shared Variables. This allows you to decide at runtime the IP address, lib name and SV name you wish to connect to. I've attached a vi snippet the demonstrats an Action Engine to handle the connection to a SV named "Parameters".
I normally store the cRIO_Settings in a .INI file that is easy to modify.

Printer Policies - DNS Name rather than IP

Is there a way to point to a DNS Name entry rather than IP address when I associate it with a printer? Reason being Networking would prefer us using DNS entries as the ips might change one day.
At this time, this fails all the time for me.

Add LPD printer using DNS name

I am trying to add a networked printer in the Print Center using LPD and the DNS name. Whenever, I type the full dns name, I get an message that says "invalid or incomplete address". I know the dns name is correct and can add it no problem to systems running OS X 10.6 and 10.7. I can also add it in 10.8 using the IP address.
Has something changed in Mountain Lion or is this a bug?

I was just on the phone with Apple support as well. The "senior advisor" I talked to said he was familiar with "some other instances" of this happening. He opened a case and told me he would get back with me as well. He did say there is no known resolution.
The initial person I sopke with told me they only support direct connection of printers, not networked printing. The senior advisor tolde me that this is an issue with non-Mountain Lion compatible drivers… We are running primarily HP and Xerox workgroup-class devices that are a few months old up to 5 or 6 years old. They all print fine in ML if we get them set up (using an IP address). We are a publisher and would notice very quickly if print drivers didn't work correctly.
Hopefully, others reading this post will contact Apple as well. The squeaky wheel gets the attention. Will update this post when I hear back.

Unity Express Backup: Can we use DNS name of FTP server instead of IP address?

Gentlemen!
In the Unity Express system, can we use DNS name of FTP server (Microsoft FTP Server) instead of IP address in the General configuartion for Backup Server?
e.g. FTP://FTP_Server_Name/Directory
Additionally we need to configure/add DNS server name in the Domain Name settings under system menu. Is there any additional configuration would require for setting up FTP server with DNS entry & above config?

Backing Up and Restoring Data
Last Updated: May 12, 2010
Cisco Unity Express backup and restore functions use an FTP server to store and retrieve data. The backup function copies the files from the Cisco Unity Express application to the FTP server and the restore function copies the files from the FTP server to the Cisco Unity Express application. The FTP server can reside anywhere in the network if the backup and restore functions can access it with an IP address or hostname.
We recommend that backups be done regularly to preserve voice-mail messages and configuration data.
Backup and restore commands are available in configuration mode and in offline mode.
•In configuration mode, commands are available to set the following parameters:
–Number of backup files to keep (the oldest file is deleted).
–URL of the FTP server where the files will be stored.
•In offline mode, perform the backup or restore procedure. Decide the following:
–Type of files to be backed up: all files (configuration and data), only configuration files, or only data files. Data files consist of voice-mail messages. Configuration files consist of all other system and application parameters.
–URL of the FTP server where the files will be stored.

Where does ARD get its "DNS Names" from?

I've been plagued with this for months now: Many of my ARD clients have bogus entries in the "DNS Name" column. Some of them are just previously used names (showing as "MacLab-02.local" when the computer is now named "MacLab-15", for example). And some of them are names that I have never actually assigned (showing as "maclab-124.local", when I've never used lower case or numbers that high).
No matter what I do, I can't seem to fix these. In the clients' Sharing prefpane, the correct .local name is showing. When I type "hostname" at the command line, the correct name shows. Using every method I've ever known to check the names, in fact, they'll show the right ones. Except in ARD.
So... where on earth is it picking up these names? How do I clear or fix that list?
Thanks!

That was never my intention (do some windows platform dependend registry stuff)
However i had a broken network entry in that specific part of the registry which chrashed my application. Now i can just delete it and my problem is gone :-)
Probably some uninstaller missed something or only partly removed it, or the entry was from some failed installation procedure - how knows?
Now it is working,

PS: Yeah some may point out (which is right) to do some good error checking/exception handling however since the app is already rolled out a proper bugfix needs time and this solution provides a quickfix to make it work instantly...

Getting single "generic" WLS 4.5.1 app to serve multiple DNS names, including SSL

Hi everybody,
I am trying to figure out a strategy to enable a single web application
based on WLS 4.5.1 (SP13) running on Linux to serve multiple DNS
names, with some specific pages to be transmitted using SSL.
While the JSP pages differ in colouring and screen layout (but not in
logic),
the entire EJB business logic is identical for all DNS names. So are the
servlets.
The application data to be presented to the user can easily be mapped,
and presently (with the application responding to a single DNS name)
it is cached using a JNDI tree. To minimize coding effort, and
to continue utilizing the present caching concept, only expanding it to
support
multiple similar "virtual" applications, I would prefer to
continue using a single WLS instance when making the application "generic".
But as a consequence of this, I could only present a single SSL certificate
to the user if I had WLS answer internet HTTP requests directly.
What would you think should be done to get the browsers
"display the closed padlock while in the order form" for multiple DNS names
served by this same application instance?
One approach might be to put Apache in front of WLS, and configure it
to serve multiple virtual hosts (one for each DNS name to be served,
encoding the differences between the request URLs somehow in the ServerPath
directive, and providing a separate SSL certificate for each of those
virtual
hosts).
Does this make sense to you? Any experience in this area? Which Apache
and WL modules should I be using - which combination
of mod_proxy, mod_ssl (by Apache), mod_wl, mod_wl_ssl[_raven] ?
Any input would be greatly appreciated! Thanks in advance!
Ruben
[A minor add-on question is: Is the situation truly different with
WLS 6.0? I understand it supports virtual hosting on its own. Can multiple
(web) applications running under a single common WLS "umbrella" server
instance share the same application data? I would expect so - is this true?]

Ruben, I can't help you with the specifics of the configuration but your
general strategy seems correct to me. WLS does not handle multiple certs
and one must front it with a Web server if multiple certs are required.
