I see. The check_ntp_peer plugin must require more permissions, as I
found a machine with it on and I can reproduce this. NTP is a UDP
protocol and tends to just ignore you if you ask it things that it
isn't allowed to tell you, so that'll probably be why it says
timeout.
I'll look into what access it needs and see if I can allow it.
Cheers,
Andy

Do you have a firewall?
What do the rules look like?
Do you have a VPS that's old enough to have an IP address in the
original 212.13.194.0/24 range? If so, is your subnet mask set correctly
now that it's a /25 or have you allowed route redirect messages in?

Can you ping 212.13.195.4 ?
I looks like I still have the /24 netmask but I can ping 212.13.195.4

@ndy

We already monitor them with nagios, btw. :)

What does it do instead of working?
What does your check_ntp command actually look like?
Mine looks like:
define command {
command_name check_ntp
command_line /usr/lib/nagios/plugins/check_ntp -H $HOSTADDRESS$
}
And from some random host appears to work:
$ /usr/lib/nagios/plugins/check_ntp -H 212.13.195.4
NTP OK: Offset 0.006038069725 secs|offset=0.006038s;60.000000;120.000000;
However, this is quite an old version of Nagios so maybe newer
checks do something that require more access.

Andy

Whilst this maybe the case ;-) more bits will mean that some programs
have a significantly larger memory footprint.
Beware the shiny! ;-)
I can sympathise with you tho': sometimes I have to jump through extra
hoops to build myself appropriate 32bit binaries for my VPS.
PS: If you want a 64bit architecture just for the sake of coolness I
recommend MIPS R12K, IA-64 or even UltraSPARC ;-)

What specifically is not working?
How do you know it's not working?
What do the logs say?

I'm afraid only 32bit virtual machines are supported at the moment.
This is just to make life easier for us, but with the low amounts of
RAM in the typical VM they should actually be faster as 32bit for
most purposes.
Is there a particular reason that you need a 64bit install?
There's an open feature request for 64bit support here:
https://tools.bitfolk.com/redmine/issues/27
Please do log in (usual credentials) and vote it up if you'd like to
see it implemented.
I can see it happening in due course as it seems that the
architecture is a bit simpler than i386 and actually has fewer
quirks. Also VM memory footprints are getting larger.
Cheers,
Andy

I've not used ZFS, so I can't compare the two directly. However,
btrfs is currently less mature: we recommend having good backups
regardless of your filesystem, but we suggest that you be prepared to
use them if you're running btrfs.
That said, the latest version is pretty stable in normal use. It
supports RAID-0, -1 and -10 independently for each of data and
metadata, has independently-moutable subvolumes and copy-on-write
snapshots, and supports online resize and disk insertion and removal.
It's fully checksummed, so if it encounters corrupt data it can tell
you, *and* attempt to go and read from the other copy in your RAID-1
(or -10) array -- MD RAID-1 won't do this for you, because it doesn't
have the checksums, so it can't tell which copy is good. There's a
mode for supporting SSDs.
What's not there yet, but planned: a working fsck(*),
deduplication, a cross-filesystem replication tool like ZFS's
send/receive, RAID-5/6 (in .41, probably), hierarchical storage,
per-subvolume RAID options, changing RAID levels, encryption.
Hugo.
(*) Rumour has it that we'll get the first cut of this at the end of
the month. But we've all heard that one before.

Hi,
It came to my attention yesterday that some customers were finding
our install of Cacti [1] confusing. The main problem appeared to be
that the default view upon logging in was the "Tree View", and it
wasn't obvious how to get from there to the individual graphs that
you're permitted to view.
Experienced Cacti users will know that the three buttons in the top
right corner switch between the three different graph views: "Tree",
"List" and "Preview".
The "Tree View" is what you were all seeing to begin with. "List
View" is just a textual list of links to all graphs that you're
permitted to view. "Preview View" is similar, but provides graph
thumbnails to click on.
Of these, it was suggested that "Preview View" was the most obvious,
so I have now set everyone's default view to be this. It should take
effect from your next login to Cacti.
I didn't spot anyone who had deliberately set their default view to
"Tree" or "List", but if you did, or if you just happen to prefer
the other views, you can set them as your personal default from the
"settings" tab.
If you have any problems, do let me know.
Cheers,
Andy

<zts> well it turns out that there was a miscommunication: one team
thought we were meant to be hanging ourselves; the other, that
immolation was the way forward. And so we kinda accidentally
burnt our rope.

Hi
I was just wondering, as sometimes i find free ram swings from very little,
to quite alot.
Is there a way, to work out what is using ram, and how much. to see what is
sucking ram?
Thank you
PMT
