There is serious clock skew all across the 4 CTs I have put in an OpenVZ HN which runs Debian GNU/Linux, the kernel Linux is v2.6.26, waldi tree. The HN shows correct time, the CMOS RTC is bang correct.

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.

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.
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.
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.

bigblue kernel: CPU1: Temperature above threshold, cpu clock throttled
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 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?

Running cPanel/WHM, Centos.
I've never had the above before,
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.
Can not change in 24 hour Clock mode Plesk 12?The scheduled backups start false, because in Plesk 12 running 12 hours mode.The language in Plesk is German.

View 1 Replies View RelatedI've been using Clearancerack for about 4 or 5 months now and feel I should write an honest review about them considering there really doesn't seem to be too many.
Ever since the start several months ago, I've had nothing but a pleasant experience working with Chris and clearancerack.
So, here we go they get a :
Setup: 10/10
The setup is stellar. The first server I ordered was up the night that I ordered it (only a few hours) all ready to go. The servers even come with a free apc remote reboot port!
Pricing: 10/10
You could not ask for more affordable pricing than that of ClearanceRack, considering the extraordinary support, network, and all around company. Their prices are cheaper than those of the highest quality competitors, yet provide even higher quality service!
Even collocation pricing is very affordable! I will probably be sending up a few nodes in the next several months.
Network: 10/10
There has not been one second of downtime in the month's that I've been there. There was an issue with the network routing once, using bandwidth suppliers that the DC has connections to, yet Clearancerack does not use. This was fixed within several hours as well.
The network consists of a BGP mix of Peer1, All Stream, Shaw Big Pipe, MCI and peering to TorIX.
Almost all of my users experience faster downloads around the globe on the ClearanceRack network, than several of the other networks we've used throughout the US.
Support: 11/10 - Yes 11...
The support is stellar. They provide 24/7 E-mail (it really is 24/7) and REAL HUMAN Phone support (you won't get the usual leave a message, unless they really are busy and cannot take your call).
At any time of day you email them, you'll have a response within minutes, even sales!
We've had one issue with one of our nodes in which Chris had to go into the datacenter to take a quick look. The issue was resolved in 30 minutes at the most.
Any requests we've made, whether it be licensing, IP allocations have all been handled extremely quickly, no matter what time of day it is.
Company:
Many times you'll hear people say, "They're great for a small scale company." Meaning, they're decent, but do have their downs that the higher scale competitors don't. Its not like that at Clearancerack. Every single thing about them is stellar, and the service is MUCH better than service I've received at various considered "higher scale and known" datacenters around the globe.
Clearancerack, ran by Chris - is ran by REAL people, wanting to make a REAL difference in the hosting market, and he/they are doing an amazing job at that.
You don't experience any poor customer service that you'll experience elsewhere. They are 100% honest with any sort of question, issue, or comment you may have. You WON'T get any of the lies, or uninformative information you receive elsewhere when an issue arises.
Personal:
Chris, I will continue to be working with you for many years to come, as I hope many of the current subscribers, and the future do to. Someone like you deserves the very best, and should GREATLY succeed in their business career. - Thank you for everything Chris! - You really know what hosting is all about.
Thats It!
Thanks for taking the time to read this review.
Generally you won't find a honest review with the ratings that I've given these guys, but THEY do deserve it, at the very least. I do not have one complaint about them as I do many other providers, and I've tried many throughout the globe.
I hope you will go ahead and try ClearanceRack for your dedicated solutions needs. They have no contracts, so you can sign up for one month, test out the service and make a final decision (although I can pretty much guarantee you will stay!)

I need several Windows VMs to test out some softwares and I plan on using virtualization technology to cut some costs.
I have a Linux(Debian Etch) dedicated server sitting to accomplish this.
Specs are Quad Core Xeon 2.13Ghz with 4GB Ram/500GB HDD.
Now if I were to choose between Xen 3.1 and VMWare Server for the virtualization technology which would provide better performance?
I tried Windows on Xen 3.1 with PV Drivers and it seemed some what slow, but I'm not sure what the case was there so I can't say which would provide better performance overall.
I connect to my email on my dedicated cpanel/whm server by TLS/SSL (similar to instructions here: [url]..same ports, etc.)
Today I login & get a "This server's certificate expired"
But it didn't. I purchased a NEW one June 1st. Why is thunderbird grabbing my old ssl cert? The website's https:// works perfectly.
I also checked the server ssl self-signed certs and all are up to date.
I have a PIX501 firewall with a wireless network attached to the outside interface and our local network attached to the inside interface.
I've setup access lists to permit the wireless clients attached to the outside interface to be able to access services on our inside interfaces.
The wireless clients are on a totally seperate /24 subnet.
Now everything seems to work fine with nat statements for our local wired subnets for example wirelessClients accessing the email server etc however the wireless clients cannot access the internet.
For the wireless clients to get out onto our internet connection they have to take the following path
wirelessLaptop - CiscoAccessPoint - OutsideIntPIX501 - InsideIntPIX501 - CiscoSwitch - InsideCorporatePIX515E - OutsideCorporatePIX515E - Internet
Below is a cut of some of the PIX501 config that the wireless clients are connected to.
name 10.1.1.2 accessPoint
name 10.1.1.0 WirelessLan
name 100.100.100.1 pix515fw

nat (outside) 0 WirelessLan 255.255.255.0 outside 0 0
static (outside,inside) accessPoint accessPoint netmask 255.255.255.255 0 0
static (inside,outside) InternalSubnet1 InternalSubnet1 netmask 255.255.255.0 0 0
access-group outside_access_in in interface outside
route inside 0.0.0.0 0.0.0.0 pix515fw 1
route inside InternalSubnet1 255.255.255.0 OurLocalRouter 1
So my question is how should I go about giving the access for the WirelessClients to be able to open web pages on the internet? For that to happen
the traffic has to pass through the outside interface on the 501 firewall out of the inside interface onto the local switch and then back out of our
main PIX515E to reach the destionation.
I'm fairly sure I'd need to modify the WebAccessNetwork access-list to permit WirelessLan to any against the port listings so thats not a problem I can change that
how I'm not entirely sure I to go about it with the NAT statements.
just out of interest, does anyone know a ssh command(s) to bring up your servers hardware stats? Cpu type and clock speed, memory, disks etc.
I've looked everywhere for a shell command to show cpu type with no luck.
I'm trying to establish a VPN server inside a Fedora 10 VPS under OpenVZ. Openswan or Poptop is preferred over OpenVPN because Windows has built-in support for these protocols.
It looks like the host node (it's actually the vps from myprohost.com) doesn't have the required kernel modules enabled(installed?). Take Poptop for example, if I run pppd after rpm installation, the output is like this:
[root@v ~]# /usr/sbin/pppd
/usr/sbin/pppd: This system lacks kernel support for PPP. This could be because
the PPP kernel module could not be loaded, or because PPP was not
included in the kernel configuration. If PPP was included as a
module, try `/sbin/modprobe -v ppp'. If that fails, check that
ppp.o exists in /lib/modules/`uname -r`/net.
See README.linux file in the ppp distribution for more details.
[root@v ~]# modprobe -v ppp
FATAL: Could not load /lib/modules/2.6.18-92.1.18.el5.028stab060.2/modules.dep: No such file or directory
And when I check for the availability of the encryption module "MPPE", I got the same result:
[root@v ~]# modprobe mppe
FATAL: Could not load /lib/modules/2.6.18-92.1.18.el5.028stab060.2/modules.dep: No such file or directory
Openswan complains about some missing kernel modules too. So what do I do? Do I tell the provider to enable these modules? Do they normally do that? Will the host node require a reboot after having done that?
What modules are required for Poptop and Openswan? And, do I need to tell them to re-enable these modules every time I rebuild my OS?
I wanted to list down all files owned by 'root' inside /home directory and all users directory inside /home/users including subfolders and everything!
the command below works but only works when executed within the working directory.

I've got a dedicated server running my portal. Now we plan to soon launch broadcasting, where we via a webcam + microphone will broadcast (streaming WMV media) to all our members. Our members will then be able to interact with the speakers via chatting.
Now we are currently undergoing loadtesting, with our current setup, which is:
1. dedicated server+ultrafast connection=>chatting
2. home PC with static IP and 1 MBit upload=>Video+Audio Streaming
So the member requests a page from the dedicated server, which has a chat window and a windows media player. The player will retrieve the video/audio content from the home PC. This is done by the client.
Now is pretty logical to see that there will be limitations in how many connections the home pc will be able to handle.
The question is: How do i make the dedicated server get the content from the home pc (so it only serves one connection) and then get all the clients to get their video content from the dedicated server ?
I've looked into the proxy modules for the apache server, however they (forward/reverse proxy) both passes the connection on to the remote machine and thereby not doing what I want to do.
We are running the latest Plesk 12 under CentOS 7.
While I can see the App Owncloud as Admin in the Application Vault my users cannot see that particular app in their Application pool. They can see all other apps though. Just not Owncloud.
