Good morning. Having trouble adding a NTP server to a HiPath 4000 V6. If I connect the server to ETH0, all is well, but if I connect to any of the other ports (ETH2) for example, the server is not found. I would like to keep ETH0 available for access via my laptop and really want to connect the NTP to a different port. I have tried assigning an IP address to port 2 via YAST without success. Can't be as hard as I am making it look.

This sounds like a disaster in the making.
Correct config is the customer lan is configured on eth0, or, bonded with say eth0 and eth3. That connects to your data switch. On your network is an accessible NTP server which the 4K will sync from. You administer the 4K by browsing to it over your data network.
Changes from yast are not supported, you stand a good chance of killing it. All other IP's are 0.0.0.0 because it must be a simplex system. If it's V6 R1 config is in the Portal, R1 did not support the config XML. If it's V6 R2 reconfiguration should be done via the XML (/var/opt/firstinstall/firstinst...xml) and recover_4k script.
Yes it's linux, you can do all kinds of things with it, but it's a realtime telephony system and the way it handles traffic internally between the VM's is complicated. If you make unusual changes, beware of unusual things happening.

Unusual installation, where the HiPath is not connected to ANY network. Truly isolated, to the point the only access is with a laptop plugged into eth0 (Customer LAN). If I connect the laptop to any of the other ports (except the Atlantic LAN ports), I am unable to access the switch. I am trying to connect a small NTP device directly to the switch with it's own antenna for GPS time to synchronize the HiPath. Currently run on generator power from the village, or our own diesel power plant, so the time drifts a LOT!

A normal config would be
Eth0 (and eth3 if bonded) for customer LAN
Eth2 (and eth1 if bonded) for IPDA lan, if IPDA is on a different subnet than customer LAN
Eth4 (and eth7 is bonded) for corosync clustering to a duplex processor, and quorum node if processors are separated
Eth6 (and eth5 if bonded) for atlan connect to a duplex processor.
Don't have to bond them... atlan for example if often left unbonded, but with eth5/6 assigned to atlan, then we can use eth6 to connect to duplex processor, and eth5 for laptop.
It's tempting to see those nics and think you can use them for allsorts, but you can't! There's a difference with what works, and what's supported and works!

Thanks, all. Looks like I'l be going with a small switch connected to eth0. What I find most frustrating is that in all of my documentation, it clearly states that these ports are 'freely assignable', but I can find nothing that gives me a clue as to how. I can't use a PC for the NTP source, since it would also lack an internet connection. I found a $300 NTP solution that has a built in GPS receiver that can be mounted indoors (in a window). Since these are being installed in remote parts of Alaska, that's a plus.

Well as Henry Ford said, you can have any colour you like, as long as it's black.
Never tried to run NTP from atlan 192.0.2, but, it's accessible from the platform so .. maybe. If you have a lab switch there, you could try it. Depends what other traffic the NTP box is generating - need to be careful with atlan. If it was a PC you could firewall everything but NTP...
For a remote PABX like you are talking about, I'd stay away from odd ball config and stick with the small data switch.

You CAN set your NTP clock source in YAST. If you don't have your own you can use one of the national ones as long as the system has some way to access the internet. In our company we run NTP on one of our DHCP servers.

The problem with using yast to set NTP is those changes can be undone by firstinst..xml and recover_4k, the supported method of making changes. So you can configure NTP from yast, from command line, it'll be OK and work. But one day that config can disappear because the 4K config scripts aren't aware of it.
I'm trying to remember if the NTP is specified in that setup tool or not. It's been a year since I had to use it.... 
) I do have to admit it's pretty slick!
