Replacing a TFTP server in a cluster

Replacing a TFTP server in a cluster and with everything else being the same minus the MAC address on the NIC, are there any issues I could possibly run into here?
Thank you for the help the server is an MCS7845H2.

No issues, MAC address is irrelevant on TFTP as it only matters on the Pub, simply install CUCM on the new server assigning the same IP and hostname and then restore from backup.

Have a dedicated TFTP Server for CCM cluster

Hi,
One CCM3.3(3) cluster in production, in which the publisher server was the TFPT server.
Now we need expend the system and would like to deploy a dedicated TFTP Server for the cluster. Is there anyone telling me what I should concern if I have a dedicated TFTP server other than the publisher server?
Thanks,
JJ

Hi,
I have a similar issue. I have actually a pub and a sub, the pub is also the tftp server. Following the SRND, I need a dedicated tftp server because we're almost at 1250 users, growing every day. My question, which may seem very basic, is how do I build a dedicated tftp server ?

How to reboot cluster or Tftp Server

Dears
Can you guide me how to reboot cluster and tftp server

Hi Obaid,
Please find the replies:
I have upgrade the cucm 8.5 and I uploaded the device pack, now I need to restart the tftp server.
so for this what will be the case?
1. Whether phones will restart? yes
2. Will they take new firmware yes
3. If I want old to still remain on running phones and new phones should take new firmware? u need to copy the new firmware in Phone Load Name.

7936 - Unable to contact TFTP server

I have a 7936 polycom that is displaying the error message "Cannot contact tftp server". I have reset to factory defaults, verified that it is not connected to a trunked switch port, and connected it to a known working power supply/switchport that another 7936 is working from. Only difference between two phones is firmware load versions.
Working 7936 app load = 7936.3-3-14-0 rev 16
Non-working 7936 app load = 7936.3-3-2-0 rev 14
- I can ping all tftp servers in UCCM cluster from this phone, but firmware upgrade does not work due to tftp contact failure
Is it necessary to manually upgrade firmware before tftp server(s) can be contacted? ..if so, is manual upgrade possible via bypass of the tftp service on an ip phone?
Any suggestions would be most helpful and I rate all posts!! :-)

- Yes it is in the same VLAN as the Call Mgr
- No firewall ports blocking communication to the TFTP servers
- 7936 is in the same VLAN as the Call Managers
Remember, I plugged this 7936 phone into the same port as another known working 7936 and still received TFTP communication error. I can also ping all TFTP/Call Mgr servers from this phone.
I'm really thinking that it's got to be a hardware issue with the phone. All symptoms point to that, so I opened a TAC on it this afternoon and they stated that they will simply issue an RMA for replacement. Thanks for all posted replies on this matter.

SQL Server 2012 Failover Cluster configuration questions

Hi,
I have few questions on , SQL Server 2012 Failover cluserting pleasse provide suggestions:
1) In SQL Server 2012 is there a configuration for active / passive Failover Cluster installation? If so how is it done? if you could provide any links or articles that would help.
OR
Is this been replaced by Always ON Availability Groups?
2) Also in our environment we have done active/active installation but at a time my understanding is only node has the ownership to the shared storage versus both the nodes, is that correct? If not please provide an explanation?
Any additional information would be valuable in clearing my doubts?
Thank youy
Malini=

Hi malinisethi,
If you install SQL Server in a cluster and configure Active-Passive cluster. In the first node, select “New SQL Server Failover Cluster installation” option , when we are installing Active-Passive cluster, we have to specify one virtual/network name. (Note:
For Active-Active clustering you have specify different network names as per the number of nodes). on the other nodes is similar to installing on the first node except that we have select the Add Node to a SQL Server failover cluster option from the initial
menu. For more information, there is a similar issue about SQL Server 2008 Active-Passive/Active-Active cluster installation, you can review the following article.
http://sqldbpool.com/2009/10/07/sql-server-2008-active-passive-cluster-installation/
About Active/Active SQL Cluster, two clustered SQL Server instance are created in different nodes. Then apply Active /Active configuration of both instance. There is an example about creating an Active/Active SQL Cluster using Hyper-V. you can review the
following article.

Add tftp server settings to dhcp

I have a cisco 3750g that I use to hand out DHCP addresses. I also have a pxe server I'd like to be able to use. How would I add the next-server and the pxelinux file to the dhcp?
Thank you!

In your DHCP pool, you can define both the TFTP server and the boot file using the following format:
ip dhcp pool DHCP_Pool_LAN
next-server x.x.x.x
bootfile pxelinux.0
Just replace x.x.x.x with the address of your TFTP server.

SQL Server 2005 replaced with SQL Server 2014 trying to connect front end Access as guest (read only ODBC)

We have replaced a SQL Server 2005 with a SQL Server 2014 (new physical server.) Have the new server set up to use SQL Server login OR Windows user login. Had old server connecting (for a particular DB) to front end Access (2010 or 2013) as guest for
anyone logged into the Windows NT Network with a read only ODBC connection. Have the DB in the new server set to include guest as db_datareader (with only SELECT permission for the securables of each table and view being linked) but when any Windows user not
specifically listed as a SQL DB user tries to use the front end they get an error of:
Microsoft SQL Server Login
Connection failed:
SQL State: '28000'
SQL Server Error: 18456
[Microsoft][OCBC SQL Server Driver][SQL Server] Login failed for user {domain\user}.
After closing that pop-up window a server login window appears. Of course, since the guest user is not specifically listed as a user in the DB that fails also. It seems like there should be a very simple solution to this, but I can't seem to find it. I want
to allow anyone logged in on the Windows system (locally) to be able to open the MS Access file (on their work station machine) and run their own (read only; select) queries on the SQL Server database. Any suggestions?
Thanks a billion in advance ----

Thanks for the response Olaf. I have now spent weeks researching this. I realize that using the guest account in most situations is not advised. As mentioned, I have restricted the guest account to allow the db_datareader role only, and have explicitly denied
all other roles, as well as allowing select only, and still have no access for the guest account.
The suggested fix in the second link you provided, of using Windows groups is not plausible for my situation either. We are a scientific field research institution, with a few long term users and lots of users that may have Windows accounts for a few months,
and then they are gone. It would be a nightmare for the network tech to try to keep a group account up to date, and we need to give access (read only, of course) to anyone logged into the system. Realize that the ONLY access of any kind to this database is
thru MS Access ACCDB, using a (by default) read only OCDB connection.
This type of access is used particularly because researchers need to be able to set up their own queries, and the MS Access query interface is particularly convenient for people who are not themselves SQL experts, yet are trying to get some very advanced
levels of output. Putting the database online is not practical because then we are back to the need for a comprehensive query interface, and just picking up general subsets of the data online (from a basic web page search feature) would be out of the question,
since the result set would involve hundreds of thousands if not millions of records.
So - that said - what exactly would you suggest, assuming we don't have the funds to buy a whole new system, and have spent plenty of money with Microsoft's Enterprise level MS Office so that all work stations have MS Access, and Microsoft's SQL Server,
as well as running our network on Microsoft's network software.

Error reading Web application occurs when starting one server in the cluster

Hi All,
          I have configured two cluster servers in the win 2000. Admin server also win

You're getting that probably because the WL instance was not shut down properly.
If that's the case, you'll need to remove an ldap lock file (with a .lok extension) in the directory of ldap files (under the server dir) .

Server 2012 Failover Cluster No Disks available / iSCSI

Hi All,
I am testing out the Failover Clustering on Windows Server 2012 with hopes of winding up with a clustered File Server once I am done.
I am starting with a single node in the cluster for testing purposes; I have connected to this cluster a single iSCSI LUN that is 100GB in size.
When I right click on Storage -> Disks and then click 'Add Disk', I get No disks suitable for cluster disks were found.
I get this, even if I add a second server to the cluster, and connect it to the iSCSI drive as well.
Any ideas?

For testing purpose you'd better spawn a set of VMs on a single physical Hyper-V host and use shared VHDX as a back clusterd storage. That would be both much easier and much faster then what you do. + it would be trivial move one of the VMs to another physical
host, shared VHDX to CSV on a shared storage and go from Test & Development to production :) See:
Shared VHDX

For a pure iSCSI scenario you may try this step-by-step guide (just skip StarWind config as you do have a shared storage already with your SAN). See:
Configuring HA File Server on Windows Server 2012 for SMB NAS
http://www.starwindsoftware.com/configuring-ha-file-server-on-windows-server-2012-for-smb-nas
Hope this helped a bit :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

How to Setup Windows TFTP Server in Windows 2008 R2

Hi,
Can anyone please let me know, how to install TFTP Server in Windows 2008 R2.
I installed Windows Deployment Service to get TFTP (got this info in some forum), but I did not see TFTP Service in the Service Manager.
I am a newbie so plz let me know the steps in details.
Thanks in advance.

James, WDS ships with a TFTP server as part of the suite of services that are required to boot from the network. The information you've posted above is not correct.
Hi Aaron,
Thanks for your clarification. Towards the WDS TFTP Server, we could find the following statement below:
You use the Windows Deployment Services Trivial File Transfer Protocol (TFTP) server to download the files that are needed to do a network boot using the Pre-Boot Execution Environment (PXE).
From:
WDS TFTP Server
I understand that the we could select Deployment Server and Transport Server during the WDS setup processing. However, neoraghav would like to install TFTP server from the Server Manger towards the Windows Server 2008 R2. I noticed the statement as followed:
The TFTP client is optional software, and marked as deprecated on Windows Vista® and later versions of the Windows operating system. A TFTP server is no longer provided by Microsoft for similar security issues.
From:
Trivial File Transfer Protocol (TFTP) Overview
I should make my reply as clear as possible. Sorry for confusion. :-(

A Server in a cluster gone down event

Hi,
          Looks like this question was asked indirectly earlier.
          I see that when 1 server is a cluster goes down, the others servers get
          a 'weblogic.rjvm.PeerGoneException'.
          Is there a way by which i can subscribe to the
          'weblogic.rjvm.PeerGoneEvent' using 'EventRegistrationDef'.
          I am using 5.1 and looking for a way at solving the isssue of Weblogic
          removing my non RMI Object from all other servers (JNDI tree) when the
          host server goes down.
          Thanks
          Mario


The API is not public.
          This non rmi object that is living in JNDI, sounds like out of band data.
          If this object doesn't contain any state you can bind it from all the
          servers but don't replicate the bindings.
          Hope this helps.

How to configure logs to be sent for TFTP server !?

hi
I want to let the router or the switch to sends the log to TFTP server, how can I do that !?
including things like debug commands results
thanks,

You want to send the logs to the Syslog server..right? Use the logging command to do it.
logging x.x.x.x is the command.
Use the logging trap command to set the level of logging.
Router(config)#logging trap ?
<0-7> Logging severity level
alerts Immediate action needed (severity=1)
critical Critical conditions (severity=2)
debugging Debugging messages (severity=7)
emergencies System is unusable (severity=0)
errors Error conditions (severity=3)
informational Informational messages (severity=6)
notifications Normal but significant conditions (severity=5)
warnings Warning conditions (severity=4)
<cr>

Change default block size on tftp server

Is there a way to change the default block size on the tftp server so that it defaults to 1024 instead of 512
I am aware that the client can accomplish this by:
tftp> tsize
tftp> blkzise 1024
but I don't want the client to have to enter these additional commands.

Were you ever able to get an answer on this? I have the same question.
