The Java Garabe Collector (GC) is running every time when some of the objects are not more used and have no references to other objects in use. If you have a problem with the performance of your application, please update the value for the heap size. The best is to set the starting heap size and maximum heap size to the same value, so i suggest to use -Xms1024m -Xmx1024m. The first option is for the starting heap size value and the second is for the max heap size value.

I have added this to .bashrc:


# HISTORY FILE
export HISTIGNORE="&:[ ]*:exit"
export HISTSIZE=10000
export HISTCONTROL=erasedups


After a while, here is the list of top 10 most used commands in bash:

$ history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -rn|head -10

1512 cd
1335 hg
869 ls
470 sudo
408 rm
391 ssh
353 less
274 mv
231 find
225 ant


First of all, to avoid that a user is logged forever into the server, SSH can deal with an idle timeout interval. After this interval has passed, the idle user will be automatically logged out.
In /etc/ssh/sshd config file, enter:

# vi /etc/ssh/sshd config

Find the variable ClientAliveInterval and set this to 300 seconds (5 minutes) as follows:

ClientAliveInterval 300
ClientAliveCountMax 0

Save the file and restart ssh. On debin like systems you have to issue:
/etc/init.d/sshd restart

Second, just disable login as root.

To disable root login via SSH, update your sshd_config again with the following line:

PermitRootLogin no

Third, only use the ssh protocol in version 2. ssh protocol version 1 should be avoided and disabled in ssh config.

Please open sshd_config file and make sure the following line exists or add it there:
Protocol 2

Fourth best practice is to limit the number of users that can login to the server over ssh.

To only allow root, john and joe user to login via ssh please add the following to sshd_config file:

AllowUsers root john joe

Fifth, use strong passwords for your login.

Here is a simple but powerfull password generator function. Add this to your ~/.bashrc.


passwdgen() {
local l=$1
[ "$l" == "" ] && l=20
tr -dc A-Za-z0-9_ < /dev/urandom | head -c ${l} | xargs
}


You can pass a length argument to the passwdgen function:

$ passwdgen 15
L0kyeSv2mSGQc31

$lsof -i:80 was my friend, and really there was a httpd listening on this port. After i have killed this process i was able to start Apache on port 80, trough MAMP PRO. Strange.

If you want to upgrade you blog/wordpress installation and don’t know how, there are few new options in WordPress that make this task easy for your. Look at “Apperance”, “Plugins”, “Tools” in your WordPress Dashboard . It’s great stuff there. Use it.

Do they have something else ? Sure, they have. We know that movie stars and the whole Hollywood production is making big money . If America sell this industry to, let say, India that would be great . Angelina Jolie and Brad Pitt in the sequel Mr. and Mrs. Ramakishwa, let’s dance and don’t shoot again. Imagine sequel Bourne Identity – Meaning of Life. OK, it’s maybe a bad joke but what will be th sequel if America sell the film industry to France. Bournce Identity – raison d’être … Come on !

What they should sell, really ? I have the answer and this is a simple one. They should sell something that they really not own. That’s the way they do and make politic last 60 years. They have sold us things that we had, again and again. There is an american that sold the Moon, and he don’t own the Moon .

America should sell:

Taiwan

to China. If the price is right …. Just imagine. At the moment both parties, China and Taiwan, have enough money, if America find in the diplomatic etablishment somebody that can talk and argument like Mr. Henry Kissinger in the 70’s, the deal will be perfect, in few days.

Something about the Political status of Taiwan can be read here:

http://en.wikipedia.org/wiki/Political_status_of_Taiwan

Look at the part:

Possible military solutions and intervention

Until 1979, both sides intended to resolve the conflict militarily.[citation needed] Intermittent clashes occurred throughout the 1950s and 1960s, with escalations comprising the First and Second Taiwan Strait crises. In 1979, with the U.S. change of diplomatic recognition to the PRC, the ROC lost its ally needed to “recover the mainland.” Meanwhile, the PRC’s desire to be accepted in the international community led it to promote peaceful unification under what would later be termed “one country, two systems,” rather than to “liberate Taiwan” and to make Taiwan a Special Administrative Region.

Political status vs. Taiwan issue

Some scholarly sources as well as political entities like the PRC refer to Taiwan’s controversial status as the “Taiwan question”, “Taiwan issue”, or “Taiwan problem” (台灣問題). The ROC government does not like these terminologies, emphasizing that it should be called the “Mainland issue” or “Mainland question”, because from the ROC’s point of view, the PRC is making an issue out of or creating a problem out of Taiwan. Others use the term “Taiwan Strait Question” because it implies nothing about sovereignty and because “Cross-Strait relations” is a term used by both the ROC and the PRC to describe their interactions. However, this term is also objectionable to some because it still implies that there is an issue, which they feel is created only by the PRC.

Maybe this is one of the reasons why Obama is visiting Peking this days.

Just backup your old .htaccess and add this lines in you .htaccess on the begining :



RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/offline\.php$
RewriteRule ^(.*)$ /offline\.php [L]



Make a web page with the name offline.php with information about why your site is offline (be nice to your visitors) and upload to the root of your document directory.

Hm. After some googling i found the right tip . Issue the command ifconfig -a and see if there are vmnetX (X stands for any number) interfaces or are they only eth0 and lo as interfaces marked (maybe also a wifi interface, if enabled).
In the most cases there are not vmnet interfaces and you have to start this service with :

$ sudo /etc/init.d/vmware stop; sleep 2; sudo /etc/init.d/vmware start

This start script bring the interfaces up and when you start the vmplayer you will have a working ethernet connection.

To be able to scp from the second machine you have to edit the sshd_configuration there.

Set value for ChallengeResponseAuthentication to yes in the sshd_config and restart your sshd.

ChallengeResponseAuthentication yes

Best regards

I have a VirtualBox on my Mac and can run a guest operating system from a image also , just add to the CD/DVD the image and run the virtual machine.

But, not every Linux distribution has enabled the usb support, but i have found this www.slitaz.org SliTaz Gnu/Linux distribution that is small and beautifull for use, and also has enabled usb support that works .

As virtual machine was up and running i plug-out and plug-in the hard disk. The system has recognized the hard disks and i was able to format
the disk with the usual : fdisk /dev/sda

Ok,

i have found the solution. You have to edit the MAMP PRO php.ini file. How to find this file ? It’s tricky,
but here is the solution.
When you start MAMP PRO go in the menu File-> Edit Template -> PHP5 php.ini . This is Command 4 on the keyboard and insert the line where you have installed ioncube at line 1085 or greater.
And please be sure the ioncube_loader_dar_5.2.so file is in that folder!

zend_extension=/usr/local/ioncube/ioncube_loader_dar_5.2.so

Yes, i have installed my ioncube in /usr/local/ and it’s working like it should , now. Bye.

I never heard about this firm, now i know they have a piece of software in my iphone. That piece of software is going to send any data about me to Pinchmedia, without my knowledge. It sucks. I will jailbreak my iphone and try to install iptables there and set few chains. Hope this helps.
