I find it you are able to produce this issue with different on different host machines with different IOS on your You might try taking this issue to the hacki or GNS3 that, do your best with the options you have and the motivational speech. It's all I can do. .hacki.at/">http://7200emu.hacki.at/ et/phpBB/?sid=2ac72069d06c961aa96d64fd17a9d523">http://www.gns3.net/phpBB/?sid=2ac72069d06c961aa96d64fd17a9d523 11:20 AM, Nathan Pease wrote: Thanks Hammer! I don't understand why yours is working and mine is not, our configs look exactly the same. I played around with this again some more this morning. I was able to insert my 2500 access server into my lab topology and use it as an ntp master. If I use my real 2500 as an ntp master and one of my real 3560 switches as ntp client, everything works great. I then try to use one of my virtual routers from GNS3 as an ntp client to my real ntp master and my virtual ntp client router locks up. I had thought originally it was just the virtual ntp master that would lock up, but it is also a virtual ntp client that will lock up as well, it just seems to take I really don't get this. I have tried this in Windows and Ubuntu on two different computers with several diffrent ios versions. Unless somebody has any idea on how to fix this, I am just going to have to move forward doing all my ntp with real hardware. Obviously this is not the best situation, but at least I can play around with it. I was starting to loose my confidence in my ability to do ntp. :( I also messed up one of my 2500 routers doing an ios upgrade for this, but that is for a different thread.
