Changing IPs of WiSM2 HA controllers...

hello, experts!!!
HA WiSM2 already setup and running smoothly.
Clients needed to change the IPs of service interfaces.
Can they be changed directly from console of each controller while in HA config
or
need to remove them controllers from HA config?
Removing HA config means disabling just the SSO, right?
then i can proceed with the changing of the IPs?
just wanted to be on the clear.
thanks in advance.

Service Interface has nothing to do with HA SSO.
The Service Interface IP address can be changed either through console (better) or by IP.

Changing IPS from promiscous mode to Inline mode

Hi Experts,
We are changing our IPS (aip-ssm10) mode of operation from promiscous to Inline mode. Is there any caveats or anything i need to take into consideration before doing the switch? Is there a possibility to roll back incase something doesn't go the way we planned?
I look forward to your responses.

changing from promiscous to inline and back is done with the ips-command in the ASA MPF-config. So if you run into problems you can easily switch back.
What you should do before changing to inline:
- check your alerts for false positives and eliminate them first.
- if you can't eliminate all, make sure that the risk-rating doesn't exeed the threshold for the automatic deny-action if configured.
- and of course keep monitoring your events after the switch to inline.

Change IPs on an entire server

Which instructions should I follow in the case that there is need of changing a server's IP addresses without destroying its configuration and data (services used: DNS, Web, Mail, FTP) ?
I guess I need to have a direct connection to the server over a Firewire cable since it cannot be done through SA. But how to proceed then ?
It's not an actual issue, but I want to prepare myself for such a case and so far not found any information on Apple's website or its OS X Server documentation.

6. Re-establish ARD connection with the new IP and
restart the server.
I'm pretty sure the new IP will not come into effect until after the restart (also needed after changeip anyway). So, use ARD to restart then establish connection on new IP (actually, if using ARD3 then it may recognise the change in IP itself since it knows the MAC address from previous connection).
Is there a way to check whether or not the IP change
has been applied correctly ? Something to
double-check, problems to expect (it seems you have
performed this task several times) ?
You could list steps to check each of the different items you have changed, prior to the restart. E.g. for network setup...
networksetup -getinfo "Built-in Ethernet"
If "Built-in Ethernet" is the interface you are looking for info on. You can get a list of available ones from 'networksetup -listallnetworkservices'. See 'man networksetup' for more info.
For DNS,
named-checkconf
named-checkzone zone.name path/to/zone/file
see 'man named-checkconf' and 'man named-checkzone'
Also...
dig fqdn.ofyour.server
dig -x ip.ofyour.server
Probably others I cannot think of meantime
(it seems you have
performed this task several times) ?
Only once have I had to do it on an active server. I did 'practise' many times beforehand on test servers just to see if it worked properly. I'm not quite as thorough as yourself though (no notes) but standalone servers appeared fine. Ldap masters were a different kettle of fish and I would tend to reinstall (from pre-configuation image) rather than risk the changeip. I may be being too cautious though
It does sound like a good idea to run through it all on a test install if you are likely to be at a remote location when it's needed

Changing ips

Hey folks - we currently have an installation cluster for Call Manager 4.2. Im planning on upgrading to 5 soon, but have been asked to re-ip one of the servers. Would it be better to upgrade first, then change the ip of a member server, or change the ip now? Either way - how many "gotchas" can I expect? (is there a white paper or something on changing the ip of a call manager member server?)
thanks in advance

I would recommend changing the IP address and waiting to make sure that they system is stable after the change before the upgrade. Take a look at the following link.

DNS setup on server bound to AD and using domain controllers for DNS

My server is bound to our AD network and in the network pref I have entered the two IPs for the domain controllers on our network that serve DNS.
My question is, am I right not to enable/configure and start the DNS service on the Mac server since it is getting DNS already?
If yes, how do I confirm that my Mac server is correctly listed in our domain controllers DNS? Should I be concerned that I get the following?
knws3135:~ mactech$ sudo changeip -checkhostname
Password:
Primary address = 10.31.3.135
Current HostName = knws3135.ad.ewsad.net
The DNS hostname is not available, please repair DNS and re-run this tool.

Hi
It looks all OK to me? As for the hostname having capitals could pose a problem but only if the Mac Server was its own KDC. Which it is not. If the hostname is defined as you have it now in the AD's DNS Service then leave it alone.
Sometimes even when DNS checks out OK you can still have fundamental errors that only demotion to Standalone will cure. I think this is the point that you are at now. To be honest I would do this. Judging from what you've said there would be very little to lose when you do this apart from managed preferences. These can easily be re-applyed on successful promotion.
needs to be changed so it is configured in Open Directory as connected to a Directory Server
Not sure what you mean by this?
If you have or are about to update your Server to 10.5.4 - which I recommend you do. Then you could follow this procedure:
Demote to Standalone
Stop all Services
Restart the Server
Update to 10.5.4. Restart the Server (this happens anyway)
Make sure your Server resolves on the forward and reverse pointers (again)
If you want run changeip again (you may be surprised)
Use the Active Directory plug in in Directory Utility to bind the Server to the AD. Make sure you use an AD admin account that has authority to do this. De-select 'force home directory creation on startup disk' I have a feeling this will be de-selected anyway.
After successful binding quit out of Directory Utility and launch Server Admin
Select the Open Directory Service
Change the role from Standalone to Open Directory Master
Create the Directory Administrator account's username and password. Don't be tempted to change the UID or use the system admin account's user name. You can use the same password if you wish. What I've done before in the past is to create the diradmin account on the AD first with full authority for the domain.
On successful promotion you should now see in the Overview Pane everything running apart from Kerberos which should be Stopped. This is how it should be. Apple's 10.5.4 Update has took a lot of the donkey work out of this whole process. No need for the command line. Simply click.
If you launch Directory Utility you should now see the server's loopback address has been added in the LDAPv3 Plugin. Also the Server should be topmost in the Search Order under the Authentication and Contacts field. Bind your clients first to the AD and then the OD (make sure use for authentication and contacts are unchecked).
Browse the two nodes, add your groups and apply MCX in the usual way.
Does this help?

Programmatically changing the TCP/IP address of Windows Vista / 7 / 8

Hi there!
I'm pretty new to LabVIEW (started 2 months ago) and still have a long way ahead of me, so please forgive me if anything that I ask is too basic.
I'm trying to change the IP properties of the PC via LabVIEW for some bigger software I'm working on.
I can easily do it in Windows XP using the System Exec function to call cmd.exe and then use netsh commands, as previously explained for example here:
https://forums.ni.com/t5/LabVIEW/Programmatically-changing-the-IP-address-of-Win-XP/m-p/410533/highl...
https://forums.ni.com/t5/LabVIEW/Change-IP-number-and-Subnet-mask-with-LabView/m-p/407536/highlight/...
http://forums.ni.com/t5/LabVIEW/How-to-change-the-TCP-IP-settings-of-the-LAN-connection-from-LV/m-p/...
http://forums.ni.com/t5/LabVIEW/Change-the-computer-IP-address-in-LabVIEW/m-p/167481?query.id=108803... ...
But then, since I want to run my software in Windows 7 (& by extension to any Windows OS), I have a problem: netsh asks for elevated rights.
So, the next problem is: how do I run cmd.exe (or any other programm?, by extension) as administrator (from LabVIEW)?. Note that I'm using an account with admin rights. But I would prefer not having to disable the User Account Control configuration, and I don't want to force the user to any interaction (clicking in pop-ups, or right-clicking in anything), I want it to be as automatized as possible.
I did a bit of research and couldn't find anyway to do it, neither any command to run with cmd, so the two similar solutions that came to my mind are very rudimentary and kind of dirty:
Use DLLs to make LabVIEW press the keys necessary to open cmd running as admin via key shortcuts (using a variation of https://decibel.ni.com/content/docs/DOC-29563 and the key shortcuts from here: http://www.howtogeek.com/howto/windows-vista/run-a-command-as-administrator-from-the-windows-vista-r...). Here, I open the Window menu (with LWIN), properly writes "cmd", and then uses CTRL+SHIFT+ENTER ok... but then the User Account Control appears and LabView keeps doing the commands (I want ALT+Y or LEFT & then ENTER)... without affecting to the UAC! If I make LabVIEW wait a bit and manually close the UAC I succesfully have the command prompt... but LabVIEW is still incapable of write the text that I'm giving it to him (the netsh commands). LabVIEW runs the software, but it's like the UAC & the command prompt are running in a higher? level and are not affected by LV. If I do the same over a .txt I succesfuly have the intended text. Any ideas about this?
Create a link to cmd.exe and change the properties to "Run as administrator", then use System Exec to call the link, expecting to open a command prompt with elevated rights, and then write the netsh commands either with DLLs (that might not work according to my first solution) or using the "standard input" of System Exec? (not sure if this is possible). But then System Exec gives me an error (code 2) when trying to execute the .lnk and so the command prompt does not open. The error code stands for "Error 2 occurred at an unidentified location. Possible reason(s): LabVIEW: Memory is full." Any idea about how to solve this?
The conclusion is that I'm stuck with two possible solutions none of them working.
Maybe there's a more simple solution that I didn't think about?
Solutions to these problems?
Any different proposals?
Thanks in advance for any tip or help!
Note: I titled the thread as Windows Vista, 7 & 8 since I assume all of them asks for admin rights when changing IPs. In case there are other people with the same problem, altough right now I'm only using XP & 7.
Alejandro Asensio, CLAD

First question: Why do you have to change OS properties via a custom application? I know such requirements can exist (sigh...) but nevertheless it seems a little bit weird to me ;-)
OK, now an idea:
Run cmd.exe via task scheduler. Here is a how to do it: http://maximumpcguides.com/windows-vista/run-a-program-with-administrative-privileges-without-uac-pr...

Best practice to change IP?

Hi everyone,
I need to use VPN to connect to another network. The problem is that this network uses the same IP range as mine (10.0.1.x). I know that this is a problem and should be avoided, especially since the respective network's servers even have the same IP (10.0.1.3) and offer mostly the same services!
I'm willing to change one of the two networks to avoid conflicts. Both are similar in size and setup:
• NAT Router
• Leopard Server (10.5.6)
• Some Mac clients (mostly Leopard)
• A few network printers
Is it relatively painless to change an OS X Server's IP address? I've read some contrary things, where some are stating that you need to use the changeip command in Terminal. Others say it's sufficient to change it in Sys Prefs on the server followed by updating DNS.
It's no big deal to reconfigure the router, workstations and printers at one location. But what is the correct way to change the server's IP?
Here's the services I'm using at both locations:
• AFP
• DNS
• FTP
• iCal
• Open Directory
• Printing
• Web
Thanks a lot!

Yes otherwise you have to manually enter in everything. Also passwords will be lost, just select all users besides the admin and make a default password.
So this means using changeip kind of resets my OD database and even when doing a backup before the change and re-importing it I will lose all OD accounts' passwords?
You simply go to OD and after backing up you take it from master to standalone.
Ah, ok. I thought you were talking about the 3 kinds of setup you can choose when installing OS X Server. If you do not choose the Advanced Server there, you can only use the somewhat limited Server Preferences on your server and when you try to open Server Admin you get asked if you want to convert your server to Advanced. I thought you found a way of reversing this and couldn't imagine how on earth this could be possible.
• I'm really no newbie, but I'm slightly confused by IP range notation. (ie 10.X.0.0/8 and 10.Y.0.0/8)
Not sure what you mean and where you would use this... changeip does not need this.
I was asking because Steve Krawcke was suggesting to use completely separate IP ranges, which made me think of just what exactly I can use. I don't want to be in need of changing IPs again one day, so I want to get this right.
Can someone please take the time to correct (maybe by commenting?) my statements below if I'm wrong:
• There are only some IP ranges that can be used privately and are not routed on the internet. Since I'm using a NAT router that's fine and I should use one of them.
• Most home routers today come with a default IP of 192.168.x.1 and others (i.e. Apple AirPort Base Stations) use 10.0.1.1 as the default.
• I should avoid using these in my environments. Otherwise I'll get problems with VPN users when the same IPs have been used at both ends.
So if 10.0.0.0/8 = the range 10.0.0.0–10.255.255.255 does this mean I can freely use 10.123.0.1 as my router's IP and let's say 10.123.0.2 for the server and so forth? If so, can I still use a subnet mask of 255.255.255.0 or am I forced to choose something else? I really don't need more than max 50 IP addresses locally. But I'm confused, because in classful networks 10.0.0.0/8 meant a Class A network and I'm not sure I should use this?!
Thanks!

Unexpectedly fast change of IP

I"m setting OS X Tiger Server up on an internal network. It will serve only the Macs, except for its exceptional talents like its chat server capabiility and its LDAP.
We do not currently use LDAP so this is the first LDAP setup for us.
The iMacs usualy had a string of IP addresses consecutively,until some aquired Airport cards. These changed IPs. Airport is being discontinued and our Airport Cards are now obsolete. So the IP addresses are now changing back.
The server's IP address is one of those which changed. I was not ready for the change when it happened and now I've lost what set up I've done. From the ServerAdmin GUI I can only see local configurations. However, from the commaand line, the server is still registered with its valid serial number and users which are registered locally are there along with their groups on the server so sudo id davidf shows:
uid=502(davidf) gid=502(davidf) groups=502(davidf), 74(mysql), 120(netboot), 81(appserveradm), 10(owner), 52(netusers), 12(everyone), 99(unknown), 84(jabber), 79(appserverusr), 80(admin), 70(www), 69(network)
a user unique to the server like itstudent returns nothing at all.
The original server plist I created with the ServerAdmin Assistant is still in place (as well as a new one I created with the new IP address.)
I've now run changeip and that was successfull.
1. Can I rescue any of this configuration I have already done?
2. How can I re-initialize ServerSetup so that I can begin the process again?
This is sort of like jumping into the deep end so you will learn to swim quickly, I know ...
Thanks for any help you can give me!
cheers,
Davidf

Update on this:
I am now informed that at the end of the month there will be (for altogether unrelated reasons) another IP Address change. This time the addresses will move from private class b to private class a addresses.
So, I may chalk this whole episode up to experience and simply re-install the server from scratch, as well I can use the time to get up to speed with LDAP and Imaging.
Still, my questions stand, especially the one about re-initializing the ServerSetup Assistant.

Order of steps to change IP segment address and it's resources - Windows 2008 R2

I have a 2 node cluster in windows 2008 R2 AD on an HP Proliant DL380 G6 server with an attached MSA2012sa DAS storage where the resources recite. Resources are mainly data, no apps.
I need to change the IP segment/address of the cluster & storage to a new DS3 circuit. I've tried to follow some of the discussion threads on this topic, but i'm confused.
Please advice the order I should do things:
1. in cluster manager, take resources offline, then change the cluster IP and the resources IP
    --is it possible to change ips when it's offline?
    --or should I shut down the cluster? is it possible to change when cluster is shut down?
    --where does the ip of cluster itself get changed? I rt clicked on the cluster object and there is no option to change it
       (in AD or in cluster manager).
2. in network properties of each physical node, change the public IP address
     --Should I change one at a time, reboot, then do the other?
     --Should changing node ip be done before changing cluster & resources ip?
     --anything needs to be done to the quorum disk?
Advice will be very much appreciated. I've read thru a bunch of threads on changing ip but I need to brake it down in order. Thank you.

Well, I gave it a try. Only this was on a 2012 R2 cluster, so I cannot vouch for 2008 R2. (But I have extreme faith in the cluster engineers that it most likely works the same there. Again, prove it in a lab.)
Here is what I did. I had a cluster with a single network and everything was configured on that network - let's call it old-NIC. I added another network by adding a new NIC to each node - let-s call it new-NIC. I configured that new-NIC
on a different subnet.
OLD CONFIGURATION: Cluster IP - 192.168.1.30; Cluster Access Point for clustered service 192.168.1.33; Node1 IP - 192.168.1.31; Node2 IP - 192.168.1.32
NEW, DESIRED CONFIGURATION: Cluster IP - 192.168.2.30; Cluster Access Point for clustered service 192.168.2.33; Node1 IP - 192.168.2.31; Node2 IP - 192.168.2.32
The old-NIC on node1 was configured with gateway and DNS registration. I removed the gateway and DNS registration from this NIC.
I configured new-NIC on node1 with gateway and DNS. I then issued an ipconfig /registerdns to get the new name for the node into DNS.
Repeat above steps for node2.
I went into Cluster Manager and configured both old-NIC and new-NIC to be available for both Cluster and Client access.
I selected the properties of the CAP for the service and changed the IP address to new-NIC cluster IP. When accepted, I executed another ipconfig /registerdns.
I then selected the cluster core resource IP and did the same thing - changed the IP to the new-NIC address. When accepted, I executed another ipconfig /registerdns.
Obviously during the change in the IP addresses on the cluster, services became unavailable while the services were stopped/started to reconfigure with the addresses. Once the change was made and the services back up and running, the services were
available via the new-NIC IP addresses.
There should be NO connections to the cluster during this change. After updating the IP addresses on the cluster, you might have to issue an ipconfig /flushdns from the clients so they are forced to re-query DNS to be able to find things under the
new IP addresses.
All tests were performed in lab VMs.

Can I change the IP after installation?

I bought a mini to help in migrating my limping old g4 tiger that has customized web and mailman services to Leopard. Since I have a day job and am only borderline literate in command-line tasks, I was planning on doing a clean install on the Mini and then once it is working, moving it into production. As I recall, it was a real problem changing IPs once the machine was configured. Is that still the case?

Something to note.
I setup a server and after changing the IP address I ran into some strange issues. They were not show stoppers but here is what I found.
The old ip address persists under the Replica Tree for Open Directory. It is also listed under every user and a few config variables in the ldap database. Due to this when I captured packets while diagnosing connection problems. I would see my computer trying to contact the old address.
I corrected all the entries in ldap database but it didn't "Fix" the Replica Tree list.
One last problem for me... Directory Util, adding the OD server with SSL but that's another thread.

Step by Step change of IP's in Two node Cluster WIndows 2003 server

Hi,
I am looking for step by step information for changing IP's in Two Node windows 2003 cluster setup. Information on KB on technet as well on windows site, not covering step by step details. If anyone had experience of change IP's in WIndows 2003 cluster environment,
Please share, it will be great help.
Regards,
Avnish

If you have done the setup correctly and have two separate networks, changing IPs is pretty straightforward.
Make sure both networks can carry cluster communications.
Change the NICs on ONE network (usually the private network) only.
Validate the nodes can communicate over that network.
Change the NICs on the PUBLIC network.
Change the clustered IP addresses. Note that some clustered services may require a restart to accept the new IP address.

Can IPs create problem

Hi,
We have installed oracleAS 10g and our application is deployed for sms.Now we are shifting machine in new building. In new building IPs will be change.
Please let me know, Can changed IPs create problems or 10g will work normally after change in IP.

You might want to check and see if your hostname or DNS information is going to change along with the IP. Any and all of these changes WILL affect the move, and all have to be dealt with - usually by reconfiguring the listener and server parameters. Changing these items is not a trivial task and expect a few bumps before you get things back up. The name resolution will be key to the clients, so don't forget to check the DNS records.

Two Datacenters in different geographic regions

Hi.
I'm Victor and I need your help.
Please give me advise.
I have to place servers in to different datacenters for HA.
There will be cluster of Hyper-V nodes. One node in one DC and another in the second DC.
If connection to main DC or virtual machine in first node in this DC fails this virtual machine will startup in the second DC.
I have seen topology like this
http://www.cisco.com/en/US/solutions/collateral/ns340/ns517/ns224/ns949/ns304/ns975/data_center_interconnect_design_guide.pdf
on page 13.
DCs will be have L2 link between each other.
But in one DC I have one global IPs and in another DC I have different global IP for virtual machines.
We have many clients ~ 1000 and more. it won't be efficient to change IPs on all clients in case of failure on mail DC.
Do I need my own AS and BGP in this two DCs with my own IPs that will be connected by L2 link?
How can I do it without AS?
Can somebody suggest me something where I can find some answer on my question (literature, guides)?

Report columns that aren't fields (like in an updateable report (tabular form)) cannot be referenced. I think your only likely choice is to repeat the SQL for both reports in the 3rd region taking out all the irrelevant columns and then summing these up in the SQL itself.

Wifi under windows 7 boot camp keeps dying

I have been running windows 7 64 bit under Boot Camp for just under a week, and last night have started to have some pretty serious issues with the built in wifi.
Periodically, without any consistent cause, when I am booted into Windows 7, my internet connection begins to degrade. Not disconnect or anything, just taking on like 60% packet loss or more, pings to both my default gateway (the wifi router) as well as to anything further out on the internet. My ipad, iphone, macbook pro are all fine and able to use the internet at the same time without issue, its only the imac booted into Windows 7. I can reboot with no change, still completely unusable (unable to load even a single web page) for Windows 7. reboot to OSX, no issues. Its not the router, or the ISP, its JUST when I'm in win7 using wifi. I've changed IPs, used a static DNS, measured wifi, etc. I was using this setup for almost a week before the issues started, and I'm assuming its something wrong with Windows7. Fully patched and up to date, both OSX and Win7.
I finally figured out that I can temporarily fix the problem by resetting the driver for the wifi interface under the Network Adaptor troubleshoot wizard in Windows, this buys me between 5 minutes to half an hour before the issue starts up again. Nothing else I've found will fix the issue even temporarily.
I finally ran a 50 ft ethernet cable from the imac to the router and this has for now solved the intermittent issue, but its not sustainable this way as I cannot leave the cords like this. But clearly there seems to be an issue with the wifi driver in windows that boot camp is using.
Can anyone provide some suggestions of what to look for within windows or a way to debug this more directly? I used the BootCamp assistant to burn a DVD of drivers at install time and I believe they were the most recent versions, but not sure how to check further. Device manager reports I am using the Atheros AR938x Wireless adaptor, and this is a mid-2011 27" iMac running Lion.

I'm having the same problem. Wifi loses connection after 5-ish minutes.
Wondering if it's an issue with the 802.11n drivers...? Seems a little more stable on the "g" networks.
This has been happening since the latest OS X update. I have a mid-2010 Macbook Pro 15".
