About The Clock Of The VPS At Smokyhosts

Sep 16, 2007

I select a vps of Smokyhosts last friday, but I found the clock of it an hour off the correct time,

eg. I set the timezone to UTC, the correct NTP time is 3:00, but the clock of vps is display 2:00, It's an hour before the correct time.

I think this is an error when they first set the clock of host node, I send several tickets to Smokeyhosts support, but they told me I can set to another timezone not in my country, I think this is not reasonable.

and they told me they do not allow any time change requests for the hardware node even if it's error.

Since the clock of VPS is an hour error, even if I can set another timezone not my country. but if I have a forum on this VPS, and user can set their own timezone settings, they would be puzzled to find what they seclectd timezone is always an hour off,

I must be explain this to them? I think this is not acceptable.

I understand the NTP would be impossible to all VPS, but they should ensure the host node's clock is correct relatively, now it's an hour off, I think they can correct this easily if they would like to do.

another small question is when I get the vps, Mysql was installed, but the user "mysql" is not exist in system, So mysql service can't start, I add this myself, and it's ok.

Now all other things looks well except the clock.

their support always response quickly, i'm very satisfied with them.

Clock Issues With OpenVZ

Jun 19, 2009

I have an VPS at cheapvps.co.uk since November 2007. It has worked like a charm until a week ago. Since the massive crack from last week and the subsequent shutdown & boot, the clock on my VPS is going crazy.

Clock is really accelerated, a minute in the real world equals to more than 2 minutes within the VPS. I'm having lots of problems with dates in the future, and cheapvps support team is working to get this solved with no success.

System Clock Off Continuously

May 12, 2009

One of our server's system clock seems to gradually creep away from the correct time. It has been causing us a lot of issues. After one day it becomes more than one hour off. After each minute it becomes a few seconds off.

Any ideas what could be causing this? It's uptime is ~2 months so it doesn't happen when it goes offline, it happens while it is running.

Right now we have a cronjob running ntpdate every few minutes as even with the ntpd service running it would end up off by several minutes when we would check. I have a feeling this isn't a very reliable fix though.

Online Punch Clock System

Mar 27, 2009

Let me try this question in here as I think there are many companies in here who have remote employees.

Can anyone recommend an online punch clock system to keep track of employee time in's and out's? We would need something that is easy to do payroll and it has to be online so remote users can easily access it.

Windows 2003 Clock Was Right, Now It Slow An Hour

Mar 27, 2007

I am running windows 2003, and I patched it with the timezone windows update, everything was fine, but when I looked today, the clock is one hour slow.

But when I run my php scripts, it shows the time being correct. I thought php grabbed the time from the system? Perhaps this is just a bug with the clock, and the internal system time is correct? It is the only thing I can think of.

Which CPU For Web Server Tasks? Higher Clock Speed Or More Cores

Jan 8, 2009

which type of CPU would be better for a web server that will run Windows, PHP, ColdFusion, mail, DNS, and IIS. Would a dual core CPU with a higher clock speed do better than a quad core CPU with lower clock speed? For instance, would a dual core 3 Ghz processor do better than a quad core at 2.4Ghz?

Time Keepting In Virtual Environments (clock Drift, Etc...)

Apr 17, 2007

I have worked with VMWare quite a bit, and have found that no matter what tweaking you do a clock skew of up to a minute (relative to the host clock, itself kept accurate enough via NTP) is unavoidable at times, at least for a Linux 2.6.x based guest.

Do any of the common technologies allow guests to be kept more closely in sync with the host clock and so be more accurate (assuming the host's clock isn't wide of the mark, of course)? Do some of the technologies work OK with using NTPd to regulate the guest clock (under VMWare this is bad idea as it "conflicts" with VMWares own clock synchronisation method potentially making things worse than they otherwise would be).

The reason for the question is that I'm playing with some code that will run on a few different locations and while I can use an external source to fake a clock to the accuracy I want (+/- a second or two) most of the time, I wouldn't have to if I could rely on the VM's wall-clock being that accurate. If the project goes anywhere (my toy projects usually don't!) it would use real machines, but at this stage I'd rather avoid that expense/hassle.

[kernel: Kernel BUG At Mm/rmap.c:479] Any Idea What This Is?

Mar 29, 2007

we have one box in hivelocity.net that has been down so many times this month that we were forced to remove links to siteuptime where we were once so proud of having a 99.7% uptime for 3 years in theplanet.

syslog shows that just before crashing, these entries were made:

kernel: kernel BUG at mm/rmap.c:479
kernel: invalid operand:0000 [#1]

dmesg also shows this:

...
Brought up 2 CPUs
zapping low mappings.
checking if image is initramfs... it is
Freeing initrd memory: 482k freed
NET: Registered protocol family 16
PCI: PCI BIOS revision 2.10 entry at 0xf9f20, last bus=1
PCI: Using configuration type 1
mtrr: v2.0 (20020519)
mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs.
mtrr: corrected configuration.
...

i've googled these messages and they point to ram problems.

hivelocity.net claims to have done diagnostics on the box and that there were no problems reported.

they said this is a result of a sys configuration problem made by us.

any ideas?

Kernel Headers For Virtuozzo Kernel

running centos/virtuozzo 2.6.18-028stab062.3

when i configure vmware it asks at one point for kernel header files. where would i find them to match the current kernel?

i asked at parallels forums but help there is very scarce. i checked openVZ repositories and they dont yet have headers for this version.

what are my options? i have one last windows machine left and want to run it in VMware.

Centos + Kernel 2.6.9-34.0.2- How To Upgrade Kernel

Apr 29, 2007

Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then.

Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread.

In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources.

In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS.

Apparently when they used yum it said 34.0.2 was the latest kernel.

What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.

Php Safe Mode

i need to enable php safe mode on for my joomla and i came across this

Quote:

When the php safe mode is turned off globally by default at our server end, you can still override the setting to turn it ON for only your domain by just insert the following line inside the ".htaccess" file (at Linux server):

Code:

php_value safe_mode "1"

my joomla .htaccess file:

Safe Mode OFF And Open_basedir Set...

Jan 18, 2008

I am going to run a free host, yes I know I should post this in FWHT but well, they dont answer very fast if at all.

It is very dangerous to have Safe Mode OFF on a free host, but someone was telling me about open_basedir, which makes it so they cant touch any files set outside of open_basedir. Would this be suffiecient to keep them from touching others files? I know I need to disable other functions like exec() and stuff but would open_basedir keep hackers away from others files and hacking them...
