[vls-devel] [RFC] Suggestion for cleanup "Configuring interfaces" semantics in vls.cfg

[Jean-Paul Saman]

Tooney,

I notice in the current configuration scripts a bit of chaos and unclear 
configuration items. I think it is time to rethink the configuration 
strategy here, so that it becomes easier and more natural. Of course I 
do not want to redo the complete configuration, I merely want to suggest 
a way of working (some guidelines) for new configuration items.

May I suggest some more cleanup actions?

In the current CVS for VLS a user has to fill in these sections like this:

BEGIN "Interfaces"
#  Domain        = "Inet6"              # Inet4 or Inet6
   Telnet        = "telnet"                # Port to use for that purpose
END

# Telnet Administration
BEGIN "Telnet"
#  Domain        = "Inet6"              # Inet4 or Inet6
   LocalPort     = "9999"                # Port to use for that purpose
   Use = "true"
END

Suggestion:
==========
If you look carefully to what is said, then you notice that the section 
"Interfaces" should mean something like this:

If the interface is mentioned in the "Interfaces" section, then the 
interface is going to be used. More contreet: if it lists

BEGIN "Interfaces"
#  Domain        = "Inet6"              # Inet4 or Inet6
   Telnet        = "telnet"                # Port to use for that purpose
END

Then the Telnet interface to be used is configured in section "telnet".

# Telnet Administration
BEGIN "Telnet"
   LocalPort     = "9999"                # Port to use for that purpose
END

You probably noticed that the section "telnet" only lists the 
configuration options specifically for Telnet. It does not list "Domain" 
and "Use" anymore, because they are not needed.

I took out domain from "Telnet", because according to me it is not 
likely that the same streaming machine will have a inet4 and a inet6 
interface enabled.

#  Domain        = "Inet6"              # Inet4 or Inet6

The item Use = "true" is not needed, because it the section is listed in 
the meta=section "Interfaces" then it already means it is to be used. So 
if people do not want to use it, then it should be commented out.

Conclusion:
===========
The total configuration for interfaces would become more natural, then 
it currently is. I think the "Use = true" item is not needed, because it 
is a duplication of what is being expressed in the "Interfaces" section.

I'd like to suggest the following guidelines for these configuration 
sections:

1) The "Interfaces" section should only list the interface to be used 
and all global information needed for those interfaces. Hence the 
"Domain" item.
2) The specific interface sections, e.g. Telnet should only list 
configuration items needed for that interface. No global stuff in here.


What do other people think? Agree or don't agree.

Greetings,
Jean-Paul Saman.
