Hi Frank,

What about something like jails, used in FreeBSD, XEN or something like 
that, to segregate things? I don't know, if there is something else 
besides XEN similar like jails in Linux.

Could you find a possibility to use LDAP together with mediawiki? I 
could't at first sight.

I definitely like to have services segregated on different machines or 
at least jails/s.th. like that to keep administration easier and more 
secure.

I suggest to have the wikis on a seperate machine/jail, if possible. 
Starting with the "freegis book wiki" (e.g. edu.osgeo.org/wiki), moving 
the wiki.osgeo.org to telascience secondly and lastly mapbender.org, 
which just consists of a mediawiki at the moment.

The question for me is, who will maintain and who will get access on 
mapbender.org if moved to telascience?

wiki.osgeo.org is on a good machine at the moment, but I think, best 
would be to have all under "one roof". Same with mapbender.org.

Yes, I fully agree.

Well, this is a machine "Lots of software installed, general use." - 
comment from the wiki. Wouldn't it be better not to install additional 
things, especially important services?  I cannot evaluate this machine.



Best,
Ben
