 I've got an Ldap directory inside one vserver and a postfix that
 use ldap in another vserver. I search the best way to connect to
 the ldap server with the maximum of security.

 you can simply use the 'network' connection between them,
 as it will not leave the host system (it will go over the
 loopback lo interface, and cannot be sniffed by other
 guests, given that you use a secure setup which is default)

 But each VPS by default doesn't have lo interface ? 

your VPS doesn't _show_ an lo interface (yet), but the
host for sure _has_ one, otherwise most things would
fail in your networking

 What do you mean ?

addresses assigned to the host (this includes all guest
IPs) will be known as _local_ addresses and traffic to
those addresses will _always_ go via the loopback device

 My VPS have each one a PUBLIC IP  so ?

 Could you explain me a little bite more ?

so all the public IPs will be known as local addresses
to the host (and therefore to the other guests too)
so traffic between the guests (or host and guest) via
those public ips will not leave the host (i.e. happen
on the loopback device)

 vserver technology for a minute) and use SSL connection - ldaps://
 or stunnel4
 
 the best way is IMHO using SSL connection independent on vserver
 technology ...
 
 
 that will do also, of course trading performance for 
 flexibility when you move the guests apart ...
 
   
 I'm looking closer about this but I prefer the first solution

[Vserver] What is the best way to connect from 1 vserver to other vserver within the same host ?

2006-05-05 Thread Sébastien CRAMATTE

Hello

What is the best way to connect from 1 vserver to other vserver within 
the same host ?


I've got an Ldap directory inside one vserver  and  a postfix that use 
ldap in another vserver.
I search the best way to connect to the ldap server with the maximum of 
security.


The postfix server is a public mail server. The ldap directory is private.
A  private IP on the postfix server seems to be the easier but ...  
maybe it exists a clever solution ?


Thanks for your advices and solutions

Sebastien
