Oms host ip addr change

Our OMS host ipaddress may change within the next two months. What EM configuration files do I need to update to reflect the new ip? Is this currently supported or do I have to deinstall and reinstall the OMS again?
thanks.

You will find a lot of related postings in this forum. I would suggest you do a quick search and pickup from those.

Multiple OMAs on same OMS Host

Hi -
I have not tried this but wanted to get some input if i can do it etall. I have two different OMS servers. I'm planning to install additional agent on each OMS and monitor other OMS---meaning...
OMS1 - has its own agent OMA1
OMS2 - has its own agent OMA2.
Now i want to install additional OMA on OMS1 that is target of OMS2 and install additional OMA on OMS2 that is the target for OMS1
I want to do this so OMS1 agent is monitored by OMS2 and vice versa..for addtional monitoring.
Can this be done or will there be any conflict between the two OMAs being on the same OMS?
Regards,
Ash

What you are asking about is standard procedure whenever there are multiple OMS hosts.
Just make sure you come up with a naming convention for the OMA homes so you know which is which.

What impact is there on ODSEE (11.1.1.3) if host IP address changes?

We are upgrading hardware and DS software.
First we install ODSEE on a new host. Then we migrate the Directory schema and data from iPlanet 5.1 to ODSEE 11.1.1.3 on the new host.
What we would like to do next is to change the ODSEE host's IP number back to the original iPlanet's host's IP address.
What problems are there in ODSEE if/when host IP address changes?

As long as the directory server is able to use a constant host name and FQDN, it should not matter that the IP address for that host changes. You are well advised to test before doing it in production but I do not consider this to be a problem.

[SOLVED] openssl: REMOTE HOST IDENTIFICATION HAS CHANGED! Hacked?

There's a bit of Windowsisms in here, but one of the main questions is about openssl. As well, this post could help others regardless of the OS involved.
I remote into a Windows 7 workstation at my work using xfreerdp going through Server 2008 R2. RDP is closed at the firewall to all but two IP addresses and neither of those uses port 3389. I'm connecting through NTLM for authentication then the connection is encrypted using TLS. FreeRDP uses openssl to handle SSL/TLS connections.
Last week I remoted in my workstation first thing in the morning as I always do with no problems. I went to work that day and everything was normal. Later that night I went to remote in again and I got the "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" message. I followed the advice in the message and contacted the system admin:
me wrote:skottish, were there any major changes in the system that could cause the RSA fingerprint to change?
skottish wrote:I don't think so skottish. There were no changes made to the system beyond a simple update to the server's spam filters.
There was nothing major that changed on the server and I wasn't anywhere in the system that could have forced a change. The only server-side work that I did was with some accounts in Active Directory and updated Exchange's spam filters.
The way that I see it, and I may be missing something, is that there are four possibilities:
1) A MITM attack. If this is the case then it was successful and I haven't tracked it down yet
2) Someone accidentally changed something in the server
3) Someone intentionally changed something in the server
4) The server made it's own changes (which sadly wouldn't be out of character for a MS server)
We do have an outside partner that has server access, but they told me that they weren't in there and I see no evidence to the contrary.
My first question is am I missing any other possibilities?
The second is how does openssl generate the RSA fingerprint of a computer? I've read many, many pages and so far I'm not finding any answers. If I could verify the fingerprint manually, that would help.
The third is that if it is a MITM attack, what are the appropriate steps to identify it? I went through all of the ARP tables on the server and the workstation looking to see if anything is out of line and everything looks fine. I could run a capture off of our firewall and see if there's anything there, but I don't know Wireshark all that well, so I'm not sure what I would be looking for exactly.
Thoughts?

Well, there was a clock change on my end that same day. For some reason openntpd was running about two minutes behind and it had been since I migrated to systemd. I switched to ntpd in order to correct it. I can't imagine why a change on the client side would make a difference though. But, I'm open to the possibility.
--EDIT--
I tried some experiments with openntpd, ntp, and changing clocks and such, but I couldn't trigger the error. I'm still open to the possibility though.
-- RESOLUTION EDIT --
It's not worth bumping this thread over the resolution of this, but someone may be interested in what happened for their own reference later.
I realized that I was looking in the wrong direction and discovered that Windows automatically changed security keys for reasons that I don't understand yet. openssl did it's job perfectly. There was a force that wasn't the system administrator that made changes to the security of the system on a machine that hadn't changed physically. Is it possible that there has been an attack still? Yes, it's just much more unlikely now.

I used to have a podcast that had been accepted on Itunes, but my I began to have problems with my host, so I changed host and created a new podcast, and I submitted my new podcast, Apple refused, and now says the feed has already been submitted??

I used to have a podcast that had been accepted on Itunes, but my I began to have problems with my host, so I changed host and created a new podcast, and I submitted my new podcast, Apple refused, and now says the feed has already been submitted? Maybe Itunes thought that I was someone trying to copy my old podcast because I kept the same name, I tried to change the names but it looks like I'm on a blocked list...

There is a procedure for changing the feed URL for a podcast, which it seems you haven't followed: you have to add a special tag to the old feed - just submitting a new feed will have exactly the effect you describe. The proper method is described here:

Can Host ID be changed on Solaris 10

Recently upgraded an Ultra 10 from Solaris 2.6 to Solaris 10.
Problem:
We use an application that is no longer supported by the manufacturer. The application ran on the Ultra when it had Solaris 2.6. It required a specific host ID because it was originally licensed on a much older system. We cannot get a new license authorization for the application because the company is no longer in business.
To get around this, we used a program called "hid2" to change the host ID of the system. This temporarily changed the host ID on the Ultra and allowed the application to run.
After installing Solaris 10, I run the command "hid2 newhostid", and I get an error "cannot read namelist out of /dev/ksyms". The command to change the host ID is "hid2 newhostid" where newhostid is the ID required by the application.
Is this something with Solaris 10? It worked with the same hardware when the OS was Solaris 2.6.
I need an excutable program like hid2 because I'm not knowledgeable enough to compile C programs. There are several available on other websites but those that are excutabiles didn't work..
Does anyone know what to do? Do I need to install an older version of the OS? I've used 10 a little on a x86 system and like it. I'd like to upgrade this Ultra to 10.
Thank you.

Jonathan,
Keep in mind that the hints given in that Squirrel.Com link work for OBP 3.x systems, only.
When the time comes that you migrate to the next, newer system, it'll likely have an OBP design of 4.x or 5.x or 6.x, and the procedure will NOT work. The mkpl functions were deliberately removed by Sun.
So... it may now be the time to start a budget line item to save up to replace that software. Perhaps find a program that can take advantage of 21st Century computing, with 64bit and CMT architecture. <img src="images/smiley_icons/icon_smile.gif" border=0 alt="Smile">

Host name is changing all the time

Hi
The host name of my Mac is changing all the time
I recently bought a new camera and connected it
this may be the problem?
What should I do?

There are several possible causes for this problem.
1. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
2. A Mac wakes from sleep due to network traffic. This is due to a bug in OS X that may only affect some models.
3. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
4. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.
5. See also this support article.
Rename the computer in the Sharing preference pane.

Host name network change notification

I recently installed Lion Server, and it is daily (sometimes more often) producing messages about "Host name of $mymachine.local has changed to $mymachine.local" (that is, no change) ...
Any obvious reason why this should happen, and what one should do about inhibiting it?
Thanks in advance,
khb

Hello, since some days I encounert the same issue! As my MAC mini server has loads aof I/O Errors, I am wondering if this is a possible root cause for this? On the other hand, why? What happens and what has the change of the Hostname to do with I/O-Problems? Many thanks in advance for any response! Best rgds, Martin

Need advice on oracle standalone/RAC hosts public hostname changes

Hi, We just had a datacenter move and original oracle database hosts (including both standalone and RAC nodes) got changed their public hosntame, ip/vip, getway etc.
I want to know do I have to deinstall everything then reinstall or a quicker way to deal with those?
Thanks

If just the public IP's or VIP's had changed this could be done without re-installing the binaries, using oifcfg and srvctl.
However the change in hostname is not supported as per Oracle Note "RAC: Frequently Asked Questions [ID 220970.1]".
It refers to the following to reconfigure your GI.....How to Modify or Deinstall Oracle Grid Infrastructure
This reconfiguration will likely be quicker than a re-install.

Update hosts file and Change proxy settings for all users on Mac

I am in a large environment with many Mac users. We have a Windows based proxy server that we are switching over within a few weeks. So far we are manually having to go to each Mac and change the proxy settings under the users account. This is a very long and painstaking process as users are on vacation etc. and our cutoff date is fast approaching for the old proxy.
we also are having to log into each workstation as administrator go into the terminal and so sudo passwd root then change the password then do sudo vi /etc/hosts to edit the hosts file.
Is there a way to change the proxy server setting for safari and firefox globally without having to log in as each user on the Mac ?
Or is there an automated way through a script that the users can run ?
These macs authenticate to active directory. They do not have a mac server but I was told to post this question here versus the desktop area.

Most browsers include an [automatic proxy configuration (PAC) mechanism|http://en.wikipedia.org/wiki/Proxy_auto-config] and the transparent configuration of proxies, and Safari and Firefox are no different here.
The usual approach here is to have folks visit a site and select the PAC file, or to push the file out. Here is a comfiguration example from [UConn|http://helpdesk.uconn.edu/trouble/proxy/autoprox.html], and another from [Rice|http://proxy.rice.edu/setup.php], and there are others around and visible via Google.
The [pactester|http://code.google.com/p/pactester> tool might be useful, too.
If y'all get some DNS entries set up (various web browsers have [Web Proxy Auto Discovery (WPAD)|http://en.wikipedia.org/wiki/WebProxy_AutodiscoveryProtocol], when last I checked [Safari needed a little help|http://www.macosxhints.com/article.php?story=20090711031033128]) and have your firewall raise an appropriate diagnostic page, you won't have to go through this again, either.
None of this stuff is particularly specific to Mac OS X or to Safari; the PAC stuff is fairly generic, and WPAD is used with various boxes. (Try Safari with WPAD, but you might still need to reference that PAC file. And if you do, using WPAD-compliant naming would probably be a reasonable approach.)
The hosts files? You're really still using those? Any chance you can get real DNS working? That's a whole lot less work, and now is the time to deploy that; if you're going to mess with everything, then you can use that effort and that requirement to (also) move forward in your networking capabilities.

Shtting down OMS host

We need to shutdown the host running OMS and repository. Do i need to also stop the agents on all target hosts or can they stay up? I assume uploads will fail, but as long as they reconnect after OMS restart we should be OK.
Thanks

Hi,
They will be reconnected once the OMS is up.

10.5 server changes host name when changed to be member of 10.4 OD Master

Hi,
I have a Xserve with 10.4.11. This is my working OD master hostname: AAA, FQDN: AAA.domain, realm DOMAIN. Now I have a PowerMac G5, hostname BBB, FQDN BBB.domain, where I install 10.5 server.
When it comes up as stand alone, the hostname is BBB (FQDN BBB.domain), but when I then connect it (as domain member) to my OD master, it promts me to say that "AAA" is a used hostname and that it changes hostname to" AAA (2)".
In my DNS it is still identified as BBB.domain, and it is bind to the realm as BBB.
Why does it act like this?
Subsequently I can't get kerberos to work and SMB does not want to be a member of the domain (always get back to standalone instead of becoming member of the domain).

Here comes a bit more on this one. I waited and maybe this had to do with having a OD master in Tiger and the OD member on Leopard. But now both are in Leopard. And things are the same.
I have thou been studying the Console after some tips. And I'm changing the host name in Server Admin/Network to BBB (what it should be). And it seems to work fine. Name of the server changes where supposed to (what I can see). And in Console I can se that the administration tool changes host name in a variety of places.
And now I wait.
If I do nothing (the network is pretty small), nothing happens. But after a while, I login with for example Remote desktop the followingapears in Console:
+Jan 3 12:58:02 emil mDNSResponder[30]: User updated Computer Name from AAA (2) to AAA+
+Jan 3 12:58:02 emil mDNSResponder[30]: afpovertcp.tcp. service renamed from "AAA (2)" to "AAA"+

+Jan 3 12:58:03 emil mDNSResponder[30]: sftp-ssh.tcp. service renamed from "AAA" to "AAA (2)"+
+Jan 3 12:58:03 emil mDNSResponder[30]: servermgr.tcp. service renamed from "AAA" to "AAA (2)"+
+Jan 3 12:58:03 emil mDNSResponder[30]: rfb.tcp. service renamed from "AAA" to "AAA (2)"+
+Jan 3 12:58:03 emil mDNSResponder[30]: ldap.tcp. service renamed from "AAA" to "AAA (2)"+
+Jan 3 12:58:03 emil mDNSResponder[30]: net-assistant.udp. service renamed from "AAA" to "AAA (2)"+
+Jan 3 12:58:03 emil mDNSResponder[30]: adisk.tcp. service renamed from "AAA" to "AAA (2)"+
+Jan 3 12:58:03 emil mDNSResponder[30]: User updated Computer Name from AAA to AAA (2)+
+Jan 3 12:58:03 emil mDNSResponder[30]: User updated Local Hostname from AAA to AAA-2+
+Jan 3 12:58:03 emil mDNSResponder[30]: mDNS_SetFQDN - hostname unchanged+
"AAA (2) to AAA" may as well be "BBB to AAA". But I'm very surprised over that the logg claims that "User updated Computer name..." For all I know, I haven't. And note in the middle here that the mDNSResponder changes to AAA (which indeed is used - it's the OD master!!!), discovers that the name is in use, and then changes to "AAA (2)".
But why does it at all initiate a change from AAA to "AAA (2)"?
Why can't I call the server BBB?

Local host name keeps changing

My mac just started giving me a weird message when it wakes up after going to sleep. This computer's local hostname "Macintosh-8.local" is already in use on this network. The name has been changed to "xxxxxx-9.local". To change the local hostname, open System Preferences and click Sharing, then click "Edit" and type the name in the Local Hostname field. This is about the 8th time it's done this to me in the last couple weeks.

This also happened to me over the last few months when my iMac was connected to an Airport Extreme via ethernet, with wifi turned off. There are no other units on the network with the same name; eventually my iMac name incremented to (name)8756. After much research on this and other support sites (and many attempts following sugestions, including rebuild) I found that removing the ethernet connection and using wifi only fully resolved the issue. My problem is that other macs connecting to the shared disk and printer on the iMac are now slower and I cannot sleep the iMac. When connected to the AE I used "wake up on ethernet request", which I believe caused the issue due to interactions between the iMac, router and the AE bonjour service. I can connect the disk directly to the AE, but I repeatedly read that Apple do not support Time Machine on AE shared disks - even though they work better and more reliably than the shared iMac disk.
iMac now on 10.7.4; AE on 7.6.1. I do not know precisly when the issue started. The issue is totally repeatable - just connect to the AE via ethernet, turn off wifi. I suspect a bug somewhere, any help would be appreciated as I like the previous speed and do like to sleep the iMac.
