<p class="MsoNormal">Hi folks,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I have a cluster in mixed mode, last weekend we were scheduled to replace the publisher and TFTP server hardware (migrate to VMWare), cm 8.6. No version upgrade just a re-install onto VMWare.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">We ran out of maintenance window waiting for publisher to restore and db replication, so I left the TFTP server alone for another weekend. Also since pub is not registering phones or running TFTP, I did not resign the CTL file to avoid
any more cluster wide phone reboots. I plan on resigning it after I migrate TFTP this weekend.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Up until now i haven't had any issues with leaving the CTL file alone; however this morning we tried deploying some brand new 8945's and they are coming up with authentication error on their config files, which I can't figure out why at
this point. I can't reproduce the issue on my office phone (also a 8945), it happily downloads the current config files without complaint, even if I delete CTL/ITL. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Am I barking up the wrong tree here with this? shouldn't the phones just be checking the TFTP server's signature, which didnt change, against the CTL or ITL?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I asked the technician to delete the security files on the 8900s in case for some reason they had a CTL or ITL from the factory, said it didnt help. I'm having him bring a couple phones back to troubleshoot with and verify though.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">We are only doing signed configs right now, not encrypted files or control/media.<br clear="all">
