I am getting an error too I am using VMware workstation 7, Linux 4-32bit for CUCM 8.5.1,2048 Memory, 80 GB disk space, Core 2 duo , 2 processor
but for me its not installation error,
what I am doing is I am Skipping the base configuration and doing installation ,
then I am doing base configuration after installation,
it gives me error for network connectivity check,I am using Host-only for network connection
and if I ignore that and move ahead then I am getting error at NTP server configuration,
it always asks for external NTP server as ref, not like the other versions of CUCM that you say no for external NTP server and then specify the time it self on CUCM,
so does that mean I need to give External IP only for NTP server or there is some work around.
Rest is fine in my case, installation is done very smooth...
Hi, yes you can point your server to a public NTP source, but you may need to open port UDP 123 on your firewall. Here is a link to public NTP sources, http://support.ntp.org/bin/view/Servers/NTPPoolServers
I think you didn't get what I was trying to explain,
I am running VMware workstation on my Laptop, and I am connected Internet using high speed USB datacard,
so I am not actually using my laptops NIC card to connect to any device, and I am using Host-only connection type on VMware will that work or I need to change to some other type on my VMware,
I am not there in any office network or LAN....
is this is useful for you to understand my scenario...
The little trick her is to use a "cloud" to leave the captive environment of GNS. Pull a router and a cloud onto the worksheet and configure the cloud to connect to your physical or a MS-Loopback interface if you have one installed.
Then configure the router with your desired IP-address which will be the default gateway for your UCM. Configure the NTP on the router like this:
ntp master 4
ntp peer 10.1.1.1 <- the IP of CM as client
ntp server 188.8.131.52 prefer <- you don't need this if there is no connection to the internet. This is to sync the router
now bridge the VM to the same interface as you have chosen in the GNS cloud. You should have IP connectivity now
Thanx for the information will try and get back to you , just wanted to know one last thing before I try something,
I haven't installed MS-Loopback, I am going to use Ethernet port of my Laptop I have got the connectivity of GNS and my laptop,
for VMware I am using Host-only will that do or I have to select any other option,
and I am not giving IP address to the interface "VMware Network Adapter VMnet1", physically
I am only giving IP address to CUCM 10.1.1.10/24, GW 10.1.1.1
and my laptop interface "Local Area Connection" 10.1.1.1/24,
but according to above connectivity I will change my laptop "Local Area Connection" to 10.1.1.30/24
and will give 10.1.1.1 to my router on GNS and will apply respective commands for NTP,
I am aware how to set router as NTP master,
I was not aware how to connect GNS to my Laptop but from your explanation, is more than enough.
I know I am asking too much here but I have tried so many times to do installation, becouse of that I dont want to miss on anything....
I will try that also, with GNS3, and let you know how it goes.
At moment i'm using meinberg NTP software, also utilising Oxford University NTP IP's that are in the public domain.
But three attempts at 3hrs each time to load CUCMv8.6 is getting boring, my install screen crashes very late during the installition, NTP comes up fine "accessible", but the GW maybe the problem.
So i will use GNS3 and a cisco 7200 with an ios, and get back to this forum.
