How to use watchdog daemon with hardware watchdog driver interface?
Good morning!
On a CentOS 6.4 / 64 bit server I have
installed the watchdog 5.5 package.
The rpm -qi watchdog states:
The watchdog program can be used as a powerful software watchdog
daemon or may be alternately used with a hardware watchdog device such
as the IPMI hardware watchdog driver interface to a resident Baseboard
Management Controller (BMC).

[PATCH]: Heartbeat/Watchdog Patch
Dear Developers,
I've released a patch against openssh-2.5.2p2.
The patch adds heartbeat (keepalive) function to ssh(1),
and watchdog timeout function to sshd(8). The watchdog
timeout is intended to terminate user's processes
as soon as possible after the link has been lost.

Tripplite OMNI1000LCD Watchdog
Hello Nut Devs,
I'm working with usbhid-ups and a Tripplite OMNI1000LCD. I used a USB packet
sniffer to discover something cool about the watchdog feature in this unit.
(not sure if the other OMNI-X-LCD models work the same or not.) Basically
there's a single HID variable at Report ID 0x52
(UPS.OutletSystem.Outlet.ffff0092) that's one byte (0-255 int) and it
contains the Watchdog

hardware-watchdog driver problems in linux 2.6.10-xen0
Hi!
I''m trying to run w83627hf_wdt.ko watchdog driver in domain 0 (xenlinux
2.6.10-xen0), but the driver doesn''t seem to work (the machine reboots all
the time after the watchdog-timeout set in BIOS).
Is there something that could prevent the driver from accessing the
watchdog-hardware (io-ports/registers) ?
The watchdog-driver is very simple, and you can find it in

NMI: Enable watchdog by default
This patch is based on one which has been in XenServer for a very long.
To keep the trend of documentation going, it also corrects the new
command line document.

How to properly test watchdog?
CentOS 6
Hi all,
I am working on setting up sanlock + watchdog on a 2 node KVM pair.
Sanlock is working beautifully and is preventing access to the VM disks
by more than one process as it should across both boxes. I am attempting
to test failure scenarios involving watchdog, but I am having a hard
time getting it to actually reset the server.
I am running wdmd with -D so I can see the

Xen watchdog patch disposition?
Jeremy,
while originally I had hoped this patch, sitting in xen/next, would get
pushed for .37, that didn''t happen and now the .38 merge window
was missed too. Trying to get this to Linux on my own seems
inappropriate, so can I hope that you will include this with whatever
other changes you intend to push for .39?
Thanks, Jan

[patch 0/2] softlockup watchdog improvements
Here's couple of patches to improve the softlockup watchdog.
The first changes the softlockup timer from using jiffies to sched_clock()
as a timebase. Xen and VMI implement sched_clock() as counting unstolen
time, so time stolen by the hypervisor won't cause the watchdog to bite.
The second adds per-cpu enable flags for the watchdog timer. This allows
the timer to be disabled when the

em watchdog timeout on UP, 6-stable
Updated my Athlon-xp 6-stable system last night, got an em watchdog
timeout for the first time a few hours later, during a fairly
high-traffic period. System is UP but does have device apic in
the config. Any chance this is the recent race condition?
Workaround? ifconfig em0 down, ifconfig em0 up seemed to cure it,
at least for the moment.
Thanks,

[PATCH RFC] Change softlockup watchdog to ignore stolen time
The softlockup watchdog is currently a nuisance in a virtual machine,
since the whole system could have the CPU stolen from it for a long
period of time. While it would be unlikely for a guest domain to be
denied timer interrupts for over 10s, it could happen and any softlockup
message would be completely spurious.
Earlier I proposed that sched_clock() return time in unstolen
nanoseconds, which

Basic xenstore questions (building a watchdog)
I''m looking at building a xenstore-based watchdog, as described at
http://lists.xensource.com/archives/html/xen-users/2005-07/msg00597.html
However, being somewhat new to xenstore, I''d appreciate some pointers.
- What portions of the xenstore namespace should I use? I''m looking for
at least two settings writable by the DomUs: A flag to enable/disable

kernel NETDEV WATCHDOG: eth0: transmit timed out
Hi , all :
Sometimes my server network connection on Linux goes down with short
message in syslog saying: "[localhost kernel] NETDEV WATCHDOG: eth0:
transmit timed out" (or similar).
By the way , I installed the CentOS 5.4 x86_64 bit and the kernel version
was 2.6.18-164.
Has anyone experienced this problem or is it the bug of the kernel ?

bge problems in RELENG_9, bge0: watchdog timeout -- resetting
Hi,
I'm having lots of difficulties with BCM5719, which is the default

watchdog firebox has blocked ssh out
I'm behind a watchdog firebox, which has recently
blocked ssh out. I have it to where i can use port
21(the server forwards 21 to 22 that i am trying to
connect to), but somehow the watchdog firewall is also
blocking by protocol type?
the only way i can connect is if i choose raw protocol

Watchdog process?
Hello,
Is there a generic built-in way on CentOS to overlook that a specific
process is alive and re-spawn it (or just run a configured command)
when it dies?
I know how to script things so a parent will watch its child, but was
wondering whether there is something more readily available instead of
having to reinvent the wheel.
The process must be controlled via a /etc/init.d/... script and

watchdog timeout
Hello
I have some problems with 3Com nics, after a upgrade from 5.5-STABLE to
6.4-STABLE.
This machine has two 3com nics (one is LAN other is WAN) and i see too much
"watchdog timeout" on both cards.
This on/off up/down on cards, affect the interrupt to clients that are
downloading from apache web server, especially on large files.
