lexical function to provide fully qualified domain name ?

[john Dite]

I haven't got the latest OpenVMS Version to check, but is there anything planned as far as providing an additional arguement to provide the TCPIP_FULLNAME similar to the existing arguement DECNET_FULLNAME for the F$GETSYI lexical function?

[Volker Halle]

John,

I can't see anything like this in E8.2

How about using

$ x=f$trnlnm("TCPIP$INET_HOST")+"."+f$trnlnm("TCPIP$INET_DOMAIN")
$ sho sym x
X = "axpvms.invenate.local"

John,

Just looked at my notes of the TUD. Nothing Guy Peleg said points in that direction.
But couldn't you just translate the logical names TCPIP$INET_HOST and TCPIP$INET_DOMAIN and glue them together?

Greetz,

Hi Volker,

Speedy is your second name! ;-)

Thanks for the reminder. But it would still be nice to have equivalent Lexical functions that give you the info that gethostbyname and gethostbyaddr do in the context of a program.

[Jan van den Ende]

Yes, why did nobody bring this up earlier?

and the previous entries add up nicely to a friendly request to Guy!

John, your original question was for F$GETSYI to have TCPIP_FULLNAME, as an argument.
On your later entry you name "gethostbyname" and "gethostbyaddr" as the standard functions in higher languages.
I suppose the latter two have some more value than the first, but maybe if one is done, it is not very much more complex to do all?
.. and I would suggest an extension: if a node has multiple addresses (and probably associated names) would it then be possible to set up a context to scan over all values?
(say, in the spirit of F$SEARCH).

Maybe you can leave this thread collect other ideas for about a week, and then mail the URL to Guy?

Proost.

Have one on me.

Please remember that a TCP/IP host can have multiple IP adresses and multiple names. There is no easy 1:1 mapping as in DECnet.

[Jan van den Ende]

Uwe,

yes, and that is why I was suggesting the context-construct!

My appologies Jan - I have missed it.

But what sources would you include?
- local hosts database
- DNS server
-- how do you deal with round-robin and load balancers?

[Jan van den Ende]

Uwe,

(just thinking with my keyboard now)

- I guess the context construct by default would scan through ALL.

- by analogy with f$getjpi and f$getqui, the context range could be modified by f$context.

- maybe, as an analogy to f$getjpi(x,"rightslist"), it should also be possible to have ALL values at once in a string (to be able to check any presence). With the new string length limitations that will probably more feasable than at the old limit.

- or, enabling reverse lookup, return False or True for a name-address combination.

---- of course, I would gladly retract these for any better ideas!!

I'm with Jan;
a lexical function with context like f$getqui may be usefull.
