Jimmy/Johan,

 

As an update on this issue.  I believe the issue to be with conflicting
MAC's.  There are two ACS and two XP machines per physical server.  The MAC
on the two ACS/XP machines are the same on the student NIC's currently.
VMware used to let us get away with this.  But it seems to not be so
forgiving now.  Support is re-saving the snapshots after changing the MAC's
on the servers and will finish it later this week.  Hopefully this issue is
resolved after this change.  I do believe it will be.

 

Regards,

I am not sure.  Obviously I am going to have to look further into this
issue.  It seems there is a problem either with the new version of VMware
that we upgraded to or something with the build of the server.  I won't know
more until I do more testing this week.  I will let you know.

Hi

 

It is related to the Vmware ESX-environment that the pc:s are running on.
They probably uses vswitches and their CAM-table isnt accurate after moving
virtual machines to other vlans. Or something like that.

 

Tyson, just out of curiosity, can you explain?

Jimmy,

 

Had the same thing now, opened wireshark with capturing on the student nic
and the connection was working, close it and the connection to the rack is
down again.

 

Thanks you for the help on this. Do you know why wireshark affects it?

 

Johan

If you are working on proctorlabs gear is sounds like you have run into the
same problem as I had plenty of times the last week. In that case you are
experiencing problem with vmware where acs runs. Verify this in a top-down
order:

 

1) Make sure that your routes are properly configured (route print, route
add...).

Still doesnt work?

2) Reboot the ACS-machine.

Still doesn´t work?

3) Start wireshark and capture traffic on student nic. That has made magic
for me a couple of times.

STILL doesn´t work (been there!)?

4) Page Proctor labs after hours support and  ask them to reboot the ESX
host. Refer to Tyson. 

If they cant because of that would interfere with other studens/pods you are
scr*w*d for that session.

 

I think that Vol1 Lab 2 uses original ip-settings on ACS (10.1.1.100) and
this problem only shows upp when re-addressing the student nic of ACS, but
it might be that ACS hasnt been reverted correctly or something..

Hi,

 

I cannot ping the ACS server from R2. The ACS and R2 are directly connected.
A sh arp on R2 shows the ACS server, there is no arp entry for R2 on the
ACS. The routes are good on the ACS. The switch configurations are fine,
although none is required in the lab.

 

I also removed the configs on all the devices but I am having the same
problem.

 

Am I missing anything or is it possible that there is a problem on the rack?

 

Thanks

 

Johan
