Hi Clint,
Problem solved... here's the scoop:
Julien and I tried running tons of tests of the IDV running on
puelche.unl.edu with its display back to my CentOS 6.3 x86_64
VMware virtual machine. The fact that my virtual machine and
the OS on puelche.unl.edu are _identical_ had us scratching
our heads for hours. Julien created specially modified visad.jar
files that turned on debug logging with extra messages, and this
eventually showed us something that gave me an Ah Ha moment which
was that the configuration for the machine's hostname in /etc/hosts
was for ipv6 only.
Old /etc/hosts config:
127.0.0.1 localhost.localdomain localhost
::1 puelche.unl.edu puelche localhost6.localdomain6 localhost6
I changed this to be:
127.0.0.1 localhost.localdomain localhost
129.93.52.66 puelche.unl.edu puelche
::1 localhost6.localdomain6 localhost6
Since ADDE does not understand IPv6 addresses, the requests would not
be understood at any level, so servers (image, radar, and point) would
simply not respond at all. Changing /etc/hosts to the above "solved"
the problem.
Also, I took the liberty of installing the latest IDV release, v3.1u1
on your machine AND creating a runtime link to it:
[demo1@puelche ~]$ ls -alt /apps
total 92976
drwxr-xr-x. 6 root root 4096 Jan 16 17:36 .
lrwxrwxrwx 1 root root 9 Jan 16 17:36 IDV -> IDV_3.1u1
drwxr-xr-x 5 root root 4096 Jan 16 17:08 IDV_3.1u1
-rw-rw-r-- 1 demo1 demos 95179780 Jan 16 13:15 idv_3_1u1_linux64_installer.sh
dr-xr-xr-x. 30 root root 4096 Jan 14 09:59 ..
drwxr-xr-x. 4 root root 4096 Dec 17 19:01 nawips
drwxr-xr-x. 5 root root 4096 Jun 7 2012 IDV_3.0u2
drwxr-xr-x. 8 root root 4096 Aug 15 2011 wdssii
If the systemwide .cshrc file has configuration for the IDV, then
it should be changed to point at /apps/IDV, not /apps/IDV_3.0u2
I must say that this was interesting to debug!
Cheers,
Tom
