Network logins (Where did I come from?)
c...@ozemail.com.au
Hi there,
During a network login, is it possible to find out which network
node the login originated from? I've tried all the lexicals I can think
of, but nothing seems to have the information I want.
The node is written into netserver.log after the network process
disappears, but by this time, it's too late.
Thanks in advance,
--crn.

Use f$trnlnm("SYS$INPUT"). Read the network programming manual for full details
of what it all means.

There is an easier way as well: Look at the SYS$REM_NODE and SYS$REM_ID
jobwide logicals. They contain the name of the remote node and remote
user, respectively.

See logical names SYS$REM_NODE (remote node) and SYS$REM_ID (remote username).
They will contain the information you want to obtain! ;-)

You mean the information in SHOW USERS/FULL?

Others have suggested SYS$INPUT, SYS$REM_NODE and SYS$REM_ID.
I disagree.
SYS$NET is what you want.
SYS$INPUT translated to ":" whan I checked it in the context
of a task-to-task connection under DECnet phase V with VMS 7.1
SYS$REM_NODE and SYS$REM_ID can be incorrectly cached when the
same network server process is re-used by multiple connections.

You could use show users/full to get the information for yourself, but
if you are trying to get that information for your logfiles or
something you could try something like this
port = f$getjpi("","TT_ACCPORNAM")

And here's some DCL to parse the Network Control Block you get in SYS$NET:
$ parsencb:
$!
$! Parse the Network Control Block to obtain the remote node and user. We do
$! this because SYS$REM_NODE can be inaccurate when network servers are
$! reusable.
$!
$ sys$net = f$trnlnm( "sys$net" )
$ flag = f$locate( "::", sys$net )
$ slash = f$locate( "/", sys$net )
$!
$ source_node = f$extract( 0, flag, sys$net )
$ source_user = f$edit( f$extract( flag+5, slash-flag-5, sys$net ), "trim" )
$ link_number = f$cvui( 0, 16, f$extract( slash+1, 2, sys$net ) )
$ return
