[comp.sys.sequent] Indial line names

dewey@sequoia.execu.com (Dewey Henize) (10/11/90)

As system administrator, one thing I have to keep a semi-close eye on is the
activity on our indial lines.  This has been non-trivial till now, since I
had set them up in the form ttydXY, based on the original name ttyXY, as was
implied by the sequent manuals.  While this made it trivial to have a dialin
user jump out you in a 'w' listing, output from things like 'ps' was nearly
useless, since all incoming lines showed as dX (where X was not unique)
instead of XY.

I recently found out that need not be.  The 'ttyd' part is still needed by
various parts of the system, but as long as the part following the 'tty' is
unique the system could care less.  So, if any of you are in my position, you
can rename the files /dev/ttydXY to /dev/ttydY (or whatever) and go merrily
about your business.  Of course, you need to maintain uniqueness, so be careful
going across X groups, and the /etc/ttys has to reflect the change as well.

(You could even rename /dev/ttydXY files to /dev/ttydYX and accomplish the
same thing, it appears, if uniqueness is a problem.)

For those that already knew this, sorry to waste your time.  Hope it helps some
of you though, it's been a pain in the butt for me until now, and until I came
across the solution, sequent hadn't been any help.
