Hi all:
I apologize if it seems like I am trying to revive the "newbie versus expert"
thread. This is not the case. I am neither a newbie nor an expert. I am just
puzzled by the original problem which I submitted last week, which is
that the startup time of ALL tasks started at boot time (including the
mother of them all "init") appears to be changing with time as shown by the
"ps -auxw" command [examples below] without the machine having been rebooted
in between of course.
By the way, this is not a question of confusing START time with
TIME running (see below again). This looks like (possibly?...?...) a
cron problem, but I am at a loss to find out where the actual problem lies. This is
either a trivial question, in which case this should have been posted to the newbie
list [and, if that turns out to be the case, I pledge this list I will repeatedly
hit my head against a suitable wall, a suitable number of times, to be determined
by a suitable number of votes from this list...] or a question worth addressing,
even if it may have no practical consequences. But then, what is the point of
having tools to monitor processes if you cannot thrust the one single information
about when a given process actually started? As I mentioned before, I was hacked
once and found out that "ps" is one of the usual commands which is first replaced. I
do not think this is the case here (I ran an md5sum check on it) but in
doubt...
Thanks for your time.
Serge Pineault
P.S. "Explanatory" notes:
(1) Before I sent the initial message, I checked the archives on the newbie
and expert lists and could not find any related item (mind you, it is not
obvious
to do a search with "ps" or "startup" as keywords...). I also read what
I thought were the relevant manual pages (but maybe I missed some...).
(2) I sent this message to the expert list, rather than the newbie, because I
genuinely thought the answer was not obvious (I could of course be very
wrong! I might add hopefully...).
(3) Despite the fact I felt some "guilt" at starting this "newbie versus expert"
thread, there is one thing that sticks to my mind: it is that people expressing
their opinions on this list do it in a frank and polite way. In that respect,
Randy Kramer's PS to my initial message deserves mention!
And now for something completely different (I hope there are some Monty Python fans
on this list)...
Here is the output of two "ps -auxw" commands typed at 16:31 and 19:50 on the same
day. Of course the machine had not been rebooted in between. should add that
my PC is not permanently ON: I only turn it on when I (or somebody in my family)
need to use it. I also have the appropriate sections of the /var/log/messages
and crontab files and a listing of the /etc/cron* directories which I can post
later if deemed necessary.
