OpenVZ has made vzctl version 4.7 default to using ploop which is a big annoyance. No one wants it otherwise we'd use Xen or KVM.
Make sure to manually specify vzctl 4.6.1 or you will have issues with old scripts breaking since it defaults to using ploop (a single image like Xen/KVM).
Here's a list to old versions of vzctl.........
I really am a Linux fan but my comments here may not show it. Although I'm quite familiar with Linux CLI to administer servers, I find Linux GUI OS's like Ubuntu at times very clunky.
This is partially because there's no such thing as a "self-made" Linux from scratch where the UIwas designed by a single team. Linux is made up of several different projects that are generally completely separate and this lack of integratiion is a key issue that makes things f........
I don't expect this to be solved soon but some of Yahoo's DNS servers are out of whack. I changed the IPs of some nameservers of some domains and now most Yahoo users can't e-mail to those domains!
As you can see below by the "No MX or A records for mychangedomain.com", now Yahoo's DNS/mailserver DNS cache is wrong. You would think they would at least have cached the old incorrect records, but instead for some reason their DNS cache has no entry and doesn't seem........
There are all kinds of threads and links on the internet, and this seems to be a contentious issue butI don't know why.
95th percentile is either a good deal for some or a big rip off for others, Ijust said it there :)
But the reality is that for MOST people who transfer low amounts of data but burst to higher speeds such as 40mbit+ even for short periods of time, then you'll pay a lot of money to do that.
Basically 95th percentile is an-old archaic method........
I'm not impressed with OpenOffice writer, it can't beat Office XP still and speaking of that, after all these years, Wine still can't run Office XP Properly.
Back to the OpenOffice issue though, it likes to default paragraphs like this:
This is an OpenOffice Annoyance Example
See this indentation. It can be changed but Idon't see a way to default it back to the normal!
This is a great way to reduce MySQL code/mistakes/annoyance when doing things, take for example this statement:
INSERT IGNORE INTO sometable(CatName) VALUES("someitem");
Notice the "IGNORE", that is what does the magic.
Normally if the entry "someitem" existed you'd get an error message back such as "Duplicate entry for whatever". What I have normally done in PHP or whatever language is manually coded or made a........
I've tried to find a good sensible solution to cluster with and each technology has it's pros and cons and there is no perfect solution and I've found a lot of "exaggerations" in the applications, benefits and performance of these different filesystems.
I first started off with DRBD and Ihave to say it does live up to the hype, is quite reliable (although it can be annoying to match up the kernel module and user applications since they must match and whe........
Iwas getting really annoyed with this, I used full quotes around the filename and vi, cat, less all thought I was trying to pass the dash in the filename as an argument.
I didn't realize that all you have to do is just put a dash dash "--"in front.
Here's an example:cat -- "-etc-glusterfs-glusterfsd.vol.log"
Without the -- you get: cat: invalid option -- c
Try `cat --help' for more information.
This is something that annoys a lot of people, fortunately the Redhat style OS's are the most simple in this respect. I disagree that Debian's way makes sense, it is more of a hackish approach in how they implement iptables.
Anyway, for those who are using Redhat/Centos style OS's it is very simple.
Set your rules from the shell/command prompt and to save the iptables firewall rules so they are remember/loaded on boot just run this command:
There have been lots of reports like this going around and Ican confirm my 3GS with 3.0 firmware is overheating as well. It gets quite hot and actually can make your head or hand sweaty when holding it to talk, or simply holding the back cover for any reason.
It's a wonder how the device cools itself at all, considering the only thing that could ventilate air are the 2 speakers at the bottom or the single speaker on the front of the device.
Apple seems to be making........
First of all, the iPhone is crippled in many ways, but most of my complaints about functionality have been addressed through the jailbreak, Ican run apps in the background of my choosing, I can install a terminal, acccess my phone through SSH and SCP and so much more.
It even addresses the 15 minute e-mail problem, I installed a program called "PushMod" and now set the checking time to just 1 minute.
Apple should really thank the developers for this gift, it ma........
Icouldn't understand why on one system it took a few minutes to get the SSHlogin prompt when connecting to other systems. The other systems all had the UseDNS parameter set to no, which almost always resolves the login prompt delay.
The reason is Ubuntu and perhaps Debian and other distributions /etc/nsswitch.conf file
Edit yours to have the "hosts" line like so (notice that files and dns are the primary resolution choice........
This is really something the SSHServer developers should consider. The cause of this annoyance is because of failed DNS lookups on your IPaddress, which is especially common for many dedicated/col-located servers and also computers on internal NAT/private networks.
The chances are this is the cause of your SSHSlow/Delayed Login problems.

This will give you the basic info needed to browse and connect to Samba shares from the command line. From the GUI of Gnome or KDE etc, it is pretty standard and straight forward. However, I've found very little guides on how to do it from the command line and if you're like me, a nerd who prefers command line for its simplicity and for remote use, this is the way to go.
First get a list of all the Samba/SMB shares on the target.
