Hello:

This issue started few days ago. This building is a L3 segment to the
CAS. New students can get a IP address and can install the CCA agent
just fine. But after that the agent never pops up and let them login. If
the users moves to another building which is a L2 segment to CAS, the
agent pops up just fine. Now, if I use an laptop with CCA agent
installed which worked previously from the L3 building works just fine
now. But now the problem is isolated to only new CCA agent installation.
After the agent gets installed, I can ping both the CAS and CAM from the
laptop. So, IP connectivity is there from the laptop to the CAS and CAM
server. There is not access list on the any routers that will prevent
UDP 8906 packets.

I did a tcpdump and grepped for udp 8906 on the cas server and found the
following:

11:31:48.555663 IP dhcp-10-12-0-186.dyn.csudh.edu.37597 > cam1.8906:
UDP, length 83
11:31:48.555674 IP cam1 > dhcp-10-12-0-186.dyn.csudh.edu: icmp 119: cam1
udp port 8906 unreachable
11:31:50.352120 IP A01270-39XV741.dyn.csudh.edu.1317 > cam1.8906: UDP,
length 92
11:31:50.352127 IP cam1 > A01270-39XV741.dyn.csudh.edu: icmp 128: cam1
udp port 8906 unreachable
11:31:50.506156 IP 10.148.0.195.1404 > cam1.8906: UDP, length 83
11:31:50.506164 IP cam1 > 10.148.0.195: icmp 119: cam1 udp port 8906
unreachable
11:31:50.885464 IP A01270-39XV741.dyn.csudh.edu.1317 > cam1.8906: UDP,
length 92
11:31:50.885471 IP cam1 > A01270-39XV741.dyn.csudh.edu: icmp 128: cam1
udp port 8906 unreachable

I am not sure what this port 8906 unreachable means. Does it mean that
CAM is not listening on 8906 and it is supposed to?

This is a very weird problem and is frustrating. Hope someone can help.

Thanks.

It does look like the API can handle this now, but again, I'm testing  
against 4.1.1, YMMV with other versions.
See attached perl example.  Note that Audit rule failures will not  
cause a report to fail, so you need to look in all reports.
