Re: [Dspace-tech] recognise user by IP address

[Claudia Jürgen]

Hi Andrew,

you can add ip based authentication to the authentication stack in 
DSpace and define authentication rules via the config parameter 
authentication.ip.GROUPNAME = iprange[, iprange ...].

As Allen pointed out in a previous reply, for general single user
authentication (e.g. allowing a user to submit items in a particular
collection) it would not make a good choice.

However for more general authentication (e.g. allowing all users on your
university campus to read items in a protected collection) it would make a
good authentication method as it would mean that many users can get away
without the need for a DSpace account - they can be given access because
because of the machine they are using. This is a commonly used method by
publishers of electronic materials to grant access to subscribing
institutions.

DSpace has a stackable authentication system making it easy to add new
authentication methods and enable users to choose which method they log in
with. An IP authentication method has been distributed with DSpace since
version 1.5.

See: http://www.dspace.org/1_5_1Documentation/DSpace-Manual.pdf page 83.

However at present I believe there are a few issues with it, such as:

https://sourceforge.net/tracker/?func=detail&atid=119984&aid=2088431&group_i
d=19984

If you try it out, we'd love to hear your feedback about it in order that we
can improve it.

Thanks,


Stuart

hi, Gagan,

If your bitstream filenames are not stored within DC metadata it is not 
searchable.

Bitstream filenames are stored in db table "bitstream". If you really 
need this function, you have to program it by writing custom queries.

Another way out is to include the filename in DC and include this field 
in indexing.

Here are our notes from updating a DSpace installation on an Ubuntu 
Linux 8.04 Server, hope it helps;

Updating the DSpace configuration requires not only an update of the 
dspace.cfg file but also an update of the DSpace compiled files.
Download;

# wget 
http://transact.dl.sourceforge.net/sourceforge/dspace/dspace-1.5.1-release.tar.gz

Reconfigure the Dspace.cfg file;

# vim /path/to/dspace/install/config/dspace.cfg
dspace.dir = /path/to/dspace/install
dspace.url = http://localhost:8180/site_name
dspace.name = Your DSpace Site Name
db.password = ***
db.url = jdbc:postgresql://localhost:5432/db_name
default.language = en_GB
assetstore.dir = /path/to/assets
log.dir = /path/to/logs
search.dir = /path/to/search
handle.dir = /path/to/handle-server
report.dir = /path/to/reports
upload.temp.dir = /path/to/upload
mail.server=mail.server.url
mail.from.address = [EMAIL PROTECTED]
mail.admin = [EMAIL PROTECTED]

To compile the new version;

# cd /path/to/dspace-1.5.1-release/dspace/
# sudo mvn package

To update the configuration;

# cd /path/to/dspace-1.5.1-release/dspace/target/dspace-1.5.1-build.dir/
# sudo ant -Dconfig=/path/to/dspace/install/config/dspace.cfg update
# sudo /etc/init.d/tomcat5.5 force-reload

Hope this helps.

[Dspace-tech] Search on a filename

[Gagan mandayam]

Hi DSpacers,

How to *search for a particular submitted file, based on its name*?
For example, if a file's name is 'Mill Data Sheet', and I search by 
typing a part string, say 'Mill', it should list out all the

files/items present across the entire communities/collections.
( of course, each file is internally a bitstream ).

Re: [Dspace-tech] recognise user by IP address

[Allen Lam]

IP identifies a node on the network, not person, not even machine.


Someone can "steal" your IP when you are offline.

A machine can be used by different people at different time.

Some machines have randomly assigned, non-static IPs.

IPs can be changed subject to network restructuring. Network planners 
and dspace administrators are often not the same people.

For these many reasons it seems using IP as authentication is not secure 
and flexible enough in general situations.

Allen Lam.

[Dspace-tech] recognise user by IP address

[Andrew Marlow]

Hello,

please excuse my ignorance about dspace, I am new here. What do people think
to the idea of identifying users by their IP address? This would be an
alternative to logging in via the traditional username+password. This would
be associated with an administrative function that registered user groups
with IP address ranges.

Re: [Dspace-tech] DSpace/Lucene removing suffixes when searching?

[Kim Shepherd]

Hi Rafael,

 

Have a look for the “search.analyzer = “ line in your dspace.cfg file. The 
default is to use a standard English analyzer:

 

search.analyzer = org.dspace.search.DSAnalyzer

 

You’ll probably find that you have a Brasilian Portuguese analyser being used, 
and it’s “helpfully” doing stemming, gender analysis on words, etc., which 
perhaps you don’t want?

The only downside you’ll encounter going to the default DSAnalyzer is that 
characters like ç and õ won’t be automatically filtered to ‘c’ and ‘o’, which 
might make it difficult for people searching your site with 
non-international/extended keyboard layouts.

 

It is possible to easily hack DSAnalyzer.java to include just the filters you 
want, without doing full stemming, stop-words, etc. I’ve done this on our 
repositories to filter out macronised vowels which are common to words in 
Māori. If you really don’t want the full Portuguese search analyzer but do want 
the extended Latin characters filtered, I suggest sticking with DSAnalyzer and 
adding  ISOLatin1AccentFilter.java (available from Lucene) to the list of 
filters used.

 

It may be just as easy to hack org.apache.lucene.analysis.br 
(http://www.docjar.com/docs/api/org/apache/lucene/analysis/br/package-index.html)
 to only stem the words you want it to. 

 

Cheers,

 

Kim

Subject: [Dspace-tech] DSpace/Lucene removing suffixes when searching?

 

Hi,

 

We’re using Dspace 1.4.2 with the Lucene that’s shipped with it.

We don’t know if it’s a matter of configuration (apparently not) 
but Dspace (or Lucene) is removing (common) suffixes from words before 
searching.

For example (removing “ações”)

2008-12-01 17:44:04,120 INFO  org.dspace.search.DSQuery @ Final query string: 
+(((title:"alterações"))) +location:"m72"

2008-12-01 17:44:04,129 INFO  org.dspace.search.DSQuery @ Search[+title:alter 
+location:m72], sort by ("sorttitle"), Result: [EMAIL PROTECTED]

 

   Or: (again “ações”)

 

2008-12-01 17:44:58,857 INFO  org.dspace.search.DSQuery @ Final query string: 
+(((title:"modificações"))) +location:"m72"

2008-12-01 17:44:58,887 INFO  org.dspace.search.DSQuery @ Search[+title:modific 
+location:m72], sort by ("sorttitle"), Result: [EMAIL PROTECTED]

 

   With these words it wouldn’t matter (as sometimes you don’t know exactly 
the title that you are searching  but when you search for author Laura, it also 
returns results for Lauro, when there ARE results for Laura (if there wasn’t 
any I would understand).

 

2008-12-01 17:49:37,522 INFO  org.dspace.search.DSQuery @ Final query string: 
+(((tdautor:"laura"))) +location:"m72"

2008-12-01 17:49:37,530 INFO  org.dspace.search.DSQuery @ Search[+tdautor:laur 
+location:m72], sort by ("sorttitle"), Result: [EMAIL PROTECTED]

 

Is there any way to disable this through configuration or 
through Dspace or is it natural to Lucene?

 

Thanks,

 

Rafael

[Dspace-tech] PDF thumbnails

[Poulter, Dale]

Good afternoon,

 

We are moving towards implementing 1.5.1 into production (currently
1.5.0).  We hope to be able to enable thumbnails of pdf after the
migration.  However,  I have been unsuccessful in getting the package
available at  http://sts.anu.edu.au/drs/downloads/index.php to generate
pdf thumbnails.  Has anyone been able to get this to work with v1.5.x?
Thanks.

The O.P didn't say whether the site is running Tomcat behind HTTPD.
If not, then changing the port would require reconfiguring the
affected Connector element in Tomcat's server.xml, changing the
'port="8080" to 'port="80"' (and 'redirectPort="8443"' to
'redirectPort="443"').  If SSL is to be used, another Connector will
need 'port="8443"' changed to 'port="443"'.

On a Unix system, these changes would require that Tomcat be started
as a privileged user in order to have access to those low-numbered
ports.  I don't know how the O.P.'s Windows server environment affects
that.

On Unix there is a 'jsvc' wrapper which can be used to invoke Tomcat's
startup methods as root (which will open the listening sockets), get
control back, change UID to something less privileged, and invoke
Tomcat's main loop, so that the service actually runs with less
privilege but still can open listening sockets on privileged ports.
If there is a need to do this on Windows, there is probably a way to
do it, but again I don't run Tomcat on Windows and can't give specific
advice there.

Re: [Dspace-tech] Collection Administrator Permissions

[Tim Donohue]

Jesús,

At University of Illinois, we are in the process of updating that 
"delegate admins" patch to DSpace 1.5.1 XMLUI.   As soon as we have 
something stable, I'll definitely be making it available to everyone. 
I'm also hoping that I'll have a chance to make sure it works fully with 
the 1.5.1 JSPUI, but currently that's a secondary concern (as we're 
migrating to the XMLUI).

I'm hoping something will be ready by early next year, but it all 
depends on how much time I can devote to it.  Either way, I'll post a 
message across DSpace-Tech whenever it's ready to go.
