Hi hotline,
When our RTs get turned off for any length of time (more than 4
minutes), they won't allow logins anymore. The specific symptom is
that kerberos refuses the login because the time-is-out-of-bounds.
This never used to happen.
JIK's suggestion that a timed master, as he put it, is not running
on the local subnet is almost certainly the problem. I can be sure
that for the three years I've been here, timed would respond during the
startup process with something like "PREPOSTEROUSE DATE! Check and
Reset!..." and now it doesn't. This tells me we used to be able to
reach a time server and now we can't. That's certainly nothing CRL had
anything to do with.
I would say the problem started when Telecommunications "isolated" us
from the rest of the Building 11 net in late April or early may,
whenever the meltdown was that Jeff Schiller and others remember so
vividly. All the time servers are on the other part of the net and not
ours. No one saw the problem until the RTs wouldn't allow logins any
more. I note that the machines BOOT just fine and even activate. Only
at the time check of kerberos was the problem revealed.
So, how do we get a time master accessible to our newly localized subnet?

I've found that after an RT has been off for a couple of days, logins
are no longer possible because local time is too different from system
time (Kerberos tickets can't be obtained). Shouldn't local time get
reset on power-up?
In the future, please use the "sendbug" program to report bugs; this
will automatically provide us with some information that will help us
to process your report, and in addition, it will ask you questions
which will help tell you what we need to know.
Since workstations in public clusters do not usually have the
problem you describe, I can only assume that your problem is caused by
something specific to your set-up. My first guess would be that you
are not running a timed master on the CRL subnet (and I can only
assume that the problem you are having is with a CRL workstation,
since you included crlstaff as a CC in your bug report). However, I
cannot verify this, because you have not told me which workstation in
particular is giving you trouble.
Since my suspicion is that this is a problem with your subnet's
configuration, rather than a software problem, my recommendation is
that you contact the hardware hotline (send mail to "hotline" or call
x3-1410) and tell them which workstation is having this problem, and
they will look into it. If they determine that your configuration is
not at fault, they will contact "bugs" at that point and we'll take it
from there.
