Setup with more than one computer

Hi Fellas

The network topology I would like OFBiz setup is using more than one
computer using the following options: 
1. Application Server + Dbase
2. Web Server + Application Server + Dbase

Now . I would feel confident setting up:
 
Option 1. (Apps + Dbase) I will be placing the Apps and Dbase between a
firewall i.e. Apps-(192.168.0.192/24) > Firewall > Dbase-(192.168.2.100/24)

Option 2. (Web Server+ Apps + Dbase) Web Server-(192.168.1.100/24) >
Firewall > Dbase-(192.168.2.100/24) + Apps-(192.168.2.101/24)

Notice the IP Addresses and different subnet masks.  The question is: OFBiz
should be able to talk to the *dbase*, *webserver* and or *application
server* though ports only - Not relying on the same IP addressing?  In other
words, rather than relying on TCP/IP to transfer information to each node
... or do I need to route the disparate IP addressing so that each node can
see each other through IP addressing

Thanks in advance  


Phil

Re: Question

Posted by Scott Gray <le...@gmail.com>.

The relation title is usually only used if there if more than one
relationship to a particular entity, for example an entity might have two
relationships with the Party entity like FromParty and ToParty with From/To
being the title and Party being the rel-entity-name.

In a lot of cases there is no title so you just use the entity name, such as
in your case below.

Scott

As I had a NAT firewall I am not sure.  When Compiere is first loaded a
default web screen is open where access to many areas are gained through
password protection ... It may have been a password crack ... all I know is
that someone had comprimised the computer where Compiere was loaded and
changed compieres files

Re: Setup with more than one computer - Security and Apache for a web server

Posted by BJ Freeman <bj...@free-man.net>.

Phil Windows servers do have a lot of holes
one of the reasons I moved away from windows products for servers.
the one thing that most do not know is the all the user login services
are the old net lan, from dos days.
the only real security that windows machines has is the NT files system.
Since most don't clients I run into don't event use the security
permission or set them to everyone, or Admin Full, they have security
issues.

Though linux has some security issues they are not as prone to hacks as
Ms products, mostly from lack of interest, compared to Windows products.

This article does not address any security holes in TomCat or ofbiz.

RE: Setup with more than one computer - Security and Apache for a web server

Philip

I for one would be interested in knowing how they hacked port 80 if you
know.

Thanks Mike

That is exactly what I was looking for but I didn't quite know how to word
it.

I have slightly changed the subject to fit more closely to where the thread
might be heading

Thanks for the input from everyone; I have been able to glean that:

1. IP Addresses are not an issues with OFBiz's various components talking to
one another, ports and configuration of OFBiz's framework files are the
important areas to consider
2. It is possible to split OFBiz into 2-3 x nodes/servers during
installation

Half the challenge with setting up solutions such as OFBiz is know how it
thinks and what it needs to communicate between the various engines.

The reason I am interested is that I has a bad experience with Compiere.
During development I had left port 80 open through my firewall to single
computer installation and had the web server (Tomcat) hacked into and
broken.  So I am very conscious of security and I am wondered if I could
split the web server and place in DMZ with the rest of OZBiz safely sitting
behind my firewall.  If they break the web server it won't be as big an
issue to fix or protect the dbase and other parts from being compromised by
ID thieves looking credit card and other ID details

Thanks again for your input

Question

Posted by "skip@theDevers" <sk...@thedevers.org>.


I have this bit of code:

            GenericValue payment = delegator.findByPrimaryKey("Payment",
UtilMisc.toMap("paymentId", paymentId));
...
            GenericValue paymentMethod =
payment.getRelatedOne("PaymentMethod");

The javadoc for getRelatedOne sez:

Parameters:
    relationName - String containing the relation name which is the
combination of relation.title and relation.rel-entity-name as specified in
the entity XML definition file.

I did not quite understand this statement as it does not seem to make sense
in this context.  Is this parameter a concatination of "Payment" and
"Method" where Payment is the relation.title and Method is the
relation.rel-entity-name?

I kinda dont think so.  I looked in the entitydef file containg Payment and
found this:

      <relation type="one" fk-name="PAYMENT_PMETH"
rel-entity-name="PaymentMethod">
        <key-map field-name="paymentMethodId"/>
      </relation>

So, I am assuming that this particular getRelatedOne call is going to open
the PaymentMethod entity and find the related "paymentMethodId" record.

Is this correct?

Also, if I see a yyy.getRelatedOne(xxx), can I assume that xxx is the entity
name to look in and xxxId is the key name in xxx always?

Thanks
