Re: [Virtuoso-users] using the vad wiki package

Sat, 21 Mar 2009 13:22:10 +0000 

Hi Kurt,
Yes, a copy of the empty virtuoso.db with just the ODS Framework and Wiki VAD packages installed to minimize size would be useful as we can start it on a server here to see the problem hopefully. You can upload to the following FTP server and let us know when it is their and the filename: 

Hostname: download.openlinksw.com
Username: anonymous
Password: <your email addr>
Directory: upload   ;;; this is a hidden directory

whoops :-)

here's the proper commands

[root@cognac ~]# hostname
cognac.elec.qmul.ac.uk
[root@cognac ~]# dig +short 'hostname'
;; connection timed out; no servers could be reached
[root@cognac ~]# dig +short -x $(dig +short `hostname`)
[root@cognac ~]#

so actually that really doesn't look good.  is there something to
change in host.conf?


This is very strange, can remote access be provided to the new  
empty database you created so we can see this problem first hand

i'll see what i can do - there's a lot of university bureaucracy to
deal w/ tho...  is a copy of the virtuoso.db file sufficient?  i could
put this on another public server...

thanks!

Hi, Kurt --

sorry took me a while to try this - been busy at websci :-)


As an aside, check your networking setup by doing a double- 
lookup on

hostname:


# dig +short cognac.elec.qmul.ac.uk
138.37.xx.xx
# dig +short -x $(dig +short cognac.elec.qmul.ac.uk)

first command gives the ip address.  second command returns nothing.

is this right? what should be in host.conf?  sorry i'm a server  
admin

noob :-)



I don't believe the second return is correct.


hostname is a command -- when wrapped in the ` characters, it  
executes, and

its return gets substituted into the full command you're running.


Please copy and paste these three commands into your terminal  
session, so

they run on the Virtuoso host, exactly as shown --

  hostname
  dig +short `hostname`
  dig +short -x $(dig +short `hostname`)

For comparison, in my local environment, I get back --

  macted$ hostname
  dyn248.usnet.private
  macted$ dig +short `hostname`
  192.168.11.248
  macted$ dig +short -x $(dig +short `hostname`)
  dyn248.usnet.private.
  macted$


...

[Hugh] In your virtuoso.ini configuration file what is the value  
of the

"DefaultHost" param in the "[URIQA]" section as I do believe the
localhost:8890


[URIQA]
DynamicLocal                    = 1
DefaultHost                     = localhost:8890

tried changin this to hostname:80 and got the same old error.




localhost:8890 is only valid if the Web browser you're running can  
load
that URL -- including by local port forwarding -- which must be  
served up
by the Virtuoso instance.  This address generally only works when  
running

all Web clients directly on the Virtuoso host.


hostname:80 is only valid if that has been set up with port- 
forwarding

and/or vhost or similar settings, such that it reaches hostname:8890
(presuming 8890 is the Virtuoso instance's HTTP port).


Generally speaking, this should be set to the fully-qualified  
domain name
(and Virtuoso HTTP port) of the Virtuoso host server -- but that  
presumes
that the host and port are generally addressable, not behind a  
firewall.



You'll need to set this to whatever <FQDN>:<port> can be used by  
both the

Virtuoso instance itself *and* your end client to reach the Virtuoso
listener on that port.

Hope that helps,

Ted
