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

How to change IP on Oracle VM Server?

Problem statement: Need to move OVMS1 (OVM Server 1) to an IP the 10.40.40.X subnet;
~~~
environment: 2 OVS servers 2.1.2 with identical hardware (18gRAM/4cores) with shared SAN storage via OCFS2 currently validated in High Availability Config;
~~~
OVMS1 is on a 192.168.0.X IP & is setup as Server Pool Master, Util Server, & VM Server.
OVMS2 is on a 10.40.40.X IP & is setup as VM Server.
Note: currently there is 2 way bridging between these subnets and we have created many machines and had no issues...
Note: DNS is setup for the hosts and the OCFS cluster configs and such were made using fully qualified domain names (believe there are no hard-coded IPs).
Note: OVMS1 was the original server where the OCFS2 was configured and is currently the pool master & util server...
~~~
Proposed solution1: 'Change IP': Not sure yet but with no other input proposed steps:
- 1.a: make sure no VMs are running on OVMS1 & physically disconnect it from the network,
- 1.b: change the IP on the server ({color:#ff0000}*ifconfig on peth0?*{color}) via ILO on the console and shut it down.
- 1.c: change the DNS entries on the DNS server and change the cabling to be on the 10.40.40.X subnet;
- 1.d: restart OVMS1.
~~~
Proposed solution2: 'Re-install OVMS': Not sure yet but with no other input proposed steps:
- 2.a: make sure no VMs are running on OVMS1, shut down OVMS1, & physically disconnect it from the netork,
- 2.b: +{color:#ff0000}Question: Do I need to unregister OVMS1 if I am going to do an identical install with just a new IP?{color}+
- 2.b: physically change the cable to the 10.40.40.X subnet & reinstall OVS 2.1.2 with the new IP and resetup OCFS2
- 2.c: start OVMS1.
~~~
In theory Proposed solution 1 is cleanest, assuming DNS & no hard coding of IPs, as OVMS1 is already registered and it's agents are configured; Solution2 gives me some concerns about how the server/host are registred and whether the OVM Manager holds the entires or if they are local to the server... Not sure
~~~
Any ideas or input to this would be appreciated as it is critical that we change the IP of OVMS1...

First, Avi, my hat is off to you for always trying to help everyone.
~~~
This was a little more trouble than planned (likely due to being HA). After a bunch of tinkering, I am now back up with both servers now on same subnet in HA config... After IP change, OCFS stopped working, then VM Manager would not manage the VMs properly & kept losing connection with the VM Servers, then trying to re-enable HA kept overwriting the cluster files stopping the servers from coming back up...
~
Something that may be relevant is that my OVMS1 is also my initial node in my OCFS2 cluster (for HA) which I configured as OCFS2 over SAN via the documentation: "Oracle® VM Server User’s Guide Release 2.1 E10898-03:9.2.2 Creating an OCFS2 Cluster for HA"
~
I will try to summarize what worked.
~~~
Note: In retrospect, I would un-configure the HA before doing anything then re-enable when done. It looks like enabling HA overwrites the cluster.conf file so make backups of it as you go through the process... You can alternatively just leave HA enabled and 'test' when done but I preferred to re-configure it after the changes...
~~
1) As Avi said, change /etc/sysconfig/network-scripts/ifcfg-eth0:
2) If your gateway changes, then update /etc/sysconfig/network (my machine didn't work without this).
3) modify your /etc/ocfs2/cluster.conf to reflect the IPs. I recommend you reboot each server multiple times to make sure the OCFS works and auto mounts on both servers after reboots. Note that I had to reboot many times and restart/reload/reconfigure OCFS many times... More details at the bottom of this post but I hit many issues/errors including:
- connect attempt to node failed with errno -117
- connect attempt to node failed with errno -22
- Unable to stop cluster as heartbeat region still active
- Transport endpoint is not connected
4) Test your OV Manager... I was getting weird errors like I couldn't delete a VM server from the Pool & VMs wouldn't come up right on both servers (using preferred servers). I thought that the old IP may be cached somewhere so I restarted the VM Manager:
/sbin/service oc4j stop
/sbin/service oc4j start
5) OV Manager was still messed up and not able to load machines properly so I changed the Master from SV1 to SV2 using Avi's advice in the thread:
Re: Changing the Server Pool Master
6) things were working fine until I edited the pool and re-Enabled High Availability. Upon reboot of the servers the OCFS2 /OVS shared cluster didn't come up. That is where I found the /etc/ocfs2/cluster.conf was being overwritten. Replacing the over-written cluster.conf with the one that got me working in step 3 above...
7) Now I had a working infrastructure but feared that my OVMS1 was still primary for OCFS2 and now OVMS2 was now the Pool Master... I decided that I wanted OVMS1 to be primary for both so I repeated steps 5) & 6) above to re-make OVMS1 the Primary in the pool...
That is all I am up for now. I have tested that VMs come up on both OVMS's with both manual and auto preferred server settings (same VMs restarted on both servers).
Note that I have NOT gone in and tested auto-fail-over of the HA infrastructure to make sure that VMs auto-migrate or auto-restart on the other OVMS. I will take that up again later.

Apple Remote Desktop - how to change the date and time server ip address?

Our imacs keep getting out of synch with our Windows Active Directory server and when they do, users can no longer log into the imacs. The imacs this morning were more than 5 minutes fast, for example.
So, we have changed the date and time server on one of our imacs to our internal time server and that works fine. Now I would like to update all of the other imacs using a unix command in ARD. Can anyone tell me how to send this change? For this message, let's say our internal time server is 172.30.100.100

Not a problem. There are a number of other system and network setup commands that you might find useful at some time. From within the Remote Desktop Admin in the Send Unix Command window type:
networksetup -help
systemsetup -help
That will give you lists of the commands, including the one I posted above, with their basic syntax. They're handy to know.
Cheers.

Can't change password for SMTP outgoing server.

I changed my password on the server via a different method, now I need to change the password Thunderbird uses to send messages to that new password. No matter what I do, I can't seem to get Thunderbird to ask for the password again, it just keeps using the old saved password. How do I get Thunderbird to prompt me for the new password?
Oh, and this is Thunderbird 24.6.0, on Windows 7.

I have just spent several hours wrestling with the same problem.
Why the Thunderbird path ''Tools>Options>Security>Passwords>Saved Passwords'' does not casually mention that to change server provider passwords,''' simply''':
''''Remove ALL the saved password for that account. They might be there more than once. Once for inbound and another for outbound. Remove them both. Close and restart Thunderbird. It should ask you for a password the next time one is required.' '''
confounds Mozilla's usually excellent signposting, IMHO
Thanks for the inspiration, Airmail

Changed the domain of the server where BO Edge is installed

We changed the domain of the server where BO Edge resided and the domain of our database server. We are not getting the error message "Failed to register with name server. Reason: a server of this name already exists". This occurs whenever we try to start any of the servers from the CCM. What are or did we do wrong?

My understanding is that Edge is the same base code as XI 3.0 and it shouldn't have any errors when changing domain name or hostname. I don't have this version installed but in the CCM is there a CMS (+other services) or a SIA?
I'm not sure what changing the domain on the DB server would do, What type of DB are you using?

Change display name of the server under Equipment

is it possible to change the display name of the LIVE / PRODUCTION blade under equipment --> Chasis -->Servers to our own naming standards.
Attached is the screenshot of current names.
UCS Manager Version 2.1(3a)

Azmathulla,
It is not possible to change the name of the server, but you can add a label to it (see attached screenshot). And yes, it can be done during production hours, this doesn't affect the production data.
Please let me know if this answers your question.

Changed web hosting companies/mail server

I just changed web hosting companies and want to know if I change the "incoming" and "outgoing" server to the new server addresses will I lose the emails that I have for this account? Said another way, I'm going to open mail preferences, select the mail account I need to change and type in new mail server addresses?
Sorry if this has been answered before but I couldn't find an answer in a search.

Hi there, and welcome to the Discussions.
Changing the outgoing (SMTP) server should not make you loose emails, since the SMTP server is, by definition, only used to send emails. The emails you have already sent and want to keep are stored in a folder that is completely independent from your choice of SMTP server.
When it comes to changing the incoming server, that's a different business. The consequences of such a change depend on the type of the server. Is it POP? IMAP?... If it is POP, I would assume that you would not loose anything, because POP works in such a way that you download all your emails from the POP server, the emails are then deleted from the server (at least, this is the default setting), and then the reference copies of your emails are the ones on your computer, which should therefore not be touched by a change in the POP server.
If the incoming server is an IMAP server, then I don't know what will happen, but there is a risk that you could loose your emails. This is because, with IMAP, the reference copies of your emails are the ones on the server, with which your computer automatically synchronizes.
In any case, before doing anything, BACKUP YOUR EMAILS, and make sure your know how to restore these backups in case something goes wrong.
Then, I suggest you wait for someone more knowledgeable than myself to better answer your question.
Hope this helps

Change of timezone of production server

Hi All,
Currently we have business objects XI 2 release 2 on Production Server.
The timezone is in MDT.
We are going to install BOXI3.1 with SP2 on the same production server and use the import wizard to migrate the reports and the schedule instances.
After the migration, we are going to change the timezone of the Production Server to GMT.
Question: Assume the reports are scheduled at 12:00AM MDT previously.
After we change the timezone of the server, will business objects change the schedule time automatically to 06:00GMT?
I did the test in development server, it seems no issue, the business objects schedule previous show as 12:00AM, now showing 06:00GMT.
but i need to confirm with the experts here..
Thank you!

Hi,
if you tested it and it worked it should be fine.
If you need an official Statement i would recommend you open a OSS Message with SAP Support.

How to change Rendering Extension in sql server Reporting Services based on User Permissions

Hi,
I want to provide SQL server reporting services rendering extension based on user Access.
For Example
User1 can have options of Rendering to EXCEL and PDF
User2 can have a option of CSV
i read one article which is useful for report basis rendering extension changes. but i want to give user basis rendering options.
http://www.mssqltips.com/sqlservertip/3569/how-to-change-rendering-extensions-in-sql-server-reporting-services/?utm_source=dailynewsletter&utm_medium=email&utm_content=headline&utm_campaign=20150406
Thanks in advance.
GVRSPK VENI

You can use a data driven subscription for that
Maintain a table with rendering extension information for various users ie their AD user login. Then setup a data driven subscription based on table values
You will be creating a dataset with query for retrieving userid as well as rendering extensions and then just set the value as Get value from database for render Format and To properties
For more details refer

How to change the primary outgoing mail server in iphone

I am trying to change the primary outgoing mail server from Yahoo to another mail which is my internet provider. I do not know the steps to complete this in my iphone thanks

If you have more than one email account on your phone, you can change the default account under Settings>Mail, Contacts, Calendar>Default Account. Note that this setting does not appear unless you have more than one account on your phone. So, you'll need to add the email account from your ISP under Settings>Mail, Contacts, Calendars>Add New Account if you have not already done so.

How do I Change my cox incoming mail server from pop to imap

I Have a macbook pro with OS X Yosemite. I want to change the incoming cox mail server from pop to imap. I did it on my ipad and iphone but I can't do it on the mac pro. Do I need to delete the existing account and do it as a new account or can I edit the server?

It depends on what Cox has set up. Usually, you need to create a new account using IMAP. You don't want to delete the POP accounts because all your old mail is stored on your computer. You'll want to import that using Mail's Import option.

AppleFileServer stalls entire server

I had posted this question yesterday in section 10.4 by mistake. I closed it there and reposted here in 10.5 section.
During the last ~10 days I'm experiencing very weird behavior of our Leopard Server (XServe2,1 1 Intel [email protected], 10.5.7).
Some additional information inn advance: Due to holidays there is only very little traffic in the machine, according to vm_stat no swapping occurs. The system boots from an internal RAID-1 and the shares are on an external 1 TB RAID-10 connected via SCSI U320 (Atto ExpressPCI UL45 controller). ServerMonitor as well as the administration console of the external RAID-box both show no problem or warning or exceptional condition.
What happens is: AppleFileServer's CPU usage (monitored with top) suddenly raises up to and above 200%. Once this happens, the entire server seems to be hooked up and nothing else is posible: No ssh-Login, no console login, the two rows of acitivity-indicator LEDs on the server box are all lit solid.
Needless to say that ServerAdmin et. al. also fail to establish a connection or execute a task. So the only option seemes to hard shut-down by pressing the On/Off switch.
After I did that for the first time my LDAP database was corrupted but could be repaired. Since it was not possible to connect to the stalled server I had no chance to gather any more info of what might have caused the hang. Nothing valuable in the logs either.
Next day same problem again. After hard restarting the server I did a repair of all shares (four of five volumes needed repair due to DiskUtility). I as well repaired and fixed permisions on the System volume, hoping this might fixed the problem. It didn't.
I then enabled Access-Logging for AFP but the next two crashes didn' share a common pattern of AFP-activity when the stalls occured so I weeded out my assumption a particular corrupted file or directory on one of the shares could be the cause.
I finally set up three ssh-connections as root to our server and did run
top -o+command -s 5
vm_stat 10
fs_usage -f filesys AppleFileServer
Vm_stat only proved that even when hogged no swapping activity took place thus VM related problems (e.g. deadlocks during device arbitration) doen't seem to be the cause.
More interesting was the output of fs_usage about the moment the CPU-usage of AppleFileServer jumped up to 200+ % :
14:00:36.311 select S=1 127.903569 W AppleFileServer
... 2 dozen unsuspicient log entries skipped ...
14:00:46.618 select S=1 10.218817 W AppleFileServer
... more unsuspicient log entries skipped ......
14:01:39.124 select [ 4] 52.505904 W AppleFileServer
Since now i had a working ssh-session on the server (actually three of them), I exited vm_stat and issued a
kill -9 pidofAppleFileServer
which succeeded and caused launchd to immediately fork another process as shown in the following extract from top:

As one can see, all looks normal at this point but the services on the machine are still hosed up: New AFP-connections can't be opened, ServerAdmin still can't connect to the server. Obviuously the machine still is messed up and I decided to take the opportunity of having a living root-session issuing a
shutdown -r now
with the effect of this message

appearing in all three sessions. However no shutdown did take place at all. After a minute or so I noticed that all my ssh-connections were still alive and after typing return in to any of them I could issue other commands like top or ps or whatever. I eventually reissued the shutdown command without success. This is ps ax output after reppeated call to shutdown:

So finally I went into the server room and found the server contiously beeping, the yellow problem LED flashing and the blue activity LEDs both lines tunred on, console login impossible (LoginWindow didn't even receive keyboard input). So once again my only option seemed to be the On/Off switch.
Apart from the abovementioned three dubious select() system calls reported by fs_usage, I'm still not a single step further to find the reason for my problems. Why does the system loose it's responsivness. A preemptive multitasking system should IMHO guarantee a minimum of CPU time for other processes even if one gets rampant. And if the system cannot wouldn't it be a good idea to resolve the mess by panicing rather than remaining stalled?
Or is it a hardware issue? And would it be a good idea to run XServe Diagnostics on my server? Has anybody experience with this tool? Is it worth the effort neccessairy in order to run it?
Has anybody any other hints for diagnostics tools I could use to get closer to the reasons of the problems?
I must admit I'm stuck and I doubt I have collected enough reasonable information to focus the attention of an Apple support engineer on my problem.

Many many people (coming from Linux for example), make a mistake about OS X in trying to understand it as the same beast. Not to say that about you, just speaking generally.
The problem with CPU usage is it can be a bit of a red herring in OS X:
High cpu usage in and of itself is - normally - not a problem. Mac OS X is designed to make use the processor, what's the point of it sitting idle ?
CPU usage in OS X is a useless metric in general. Look at load average instead, for example.
HOWEVER when it spikes like you describe and stays that way, then it points to a problem.
How many users and what's the history of the data ?
I have seen data that was migrated from a server to another server to OS X Server cause a problem.
One of them actually can be remedied by making a new top-level folder for the sharepoint, moving all contents to the NEW folder, remove the old folder and setup the new on as your sharepoint in question.
Since you mentioned fs_usage, what files are you seeing getting pegged (via fs_usage) when the problem occurs ?
Since you're on 10.5, I find fs_usage maybe not quite as useful.
You can use fseventer (GUI tool) which hooks into fsevents,
or dtrace tools such as
sudo dtrace -n 'syscall:::entry { printf("%s\n", execname); }'
sudo dtrace -n 'syscall::open*:entry { printf("%s %s", execname, copyinstr(arg0)); }'
sudo dtrace -n 'syscall::open*:entry, syscall::unlink*:entry { printf("%s %s", execname, copyinstr(arg0)); }'
sudo dtrace -n 'syscall::open*:entry, syscall::read*:entry { printf("%s %s", execname, copyinstr(arg0)); }'

sum(trn.cost) as cost,
