writing a new trap handler
Hi,
I looked at the pid provider''s trap handler code
(usr/src/uts/sun4u/ml/trap_table.s and
usr/src/uts/sun4/os/dtrace_subr.c), and try to understand how it works.
Can someone point me some directions about trap handlers? I am interesed
in writing a new one (like dtrace does it in pid provider with the 0x38
trap id). At first, I would be pleased if I could write a trap handler
which just

Yes I suppose we can do something similar for the ticket and patch in
the right increment. We'd need to restructure the code a bit, but
its not fundamentally impossible.
We could equally apply the head hashing to

How to trigger a script in a guest after resume? (aka guest system clock incorrect after host reboot with suspended guest)
Hi
Is there a way i can trigger a script within a libvirt guest immediately
after resume? E.g. i don't see any log message that indicates to a guest
that it had been paused and was just woken up.
The problem that i am trying to solve is that when i reboot the host
(pausing all guests), the guests' system clocks are a few minutes late
after resume. The guests RTC (current_clocksource

what is the default amount of time that smbpasswd increments the sambaPwdMustChange value
So I get a phone call about my companie's controler not being able to
log into samba. About two weeks ago we migrated from Win2k Server to
Samba running on LDAP. What would be the default value that
sambaPwdMustChange would be incremented? This is NT Time Right (1 unit
for every 100 ms from 1600 right?)
I just had to bump everybody what I'm guessing is three weeks, but I

Minimising disk I/O
I'd like to get disk I/O down to a minimum for my new Centos
5.5 installation.
The machine will not be used as a web server anymore, as
that's now hosted on a cloud platform. So there are no HTTP
requests coming down the line.
If I move the SWAP partition and /var/log/ to a small spare
drive, and install Centos on the new larger drive, is there
anything else that would cause disk
