Basically I have this simplified file systems:
File system Dim. Usati Disp. Uso% Montato su
/dev/md1 10G 4,0G 5,5G 43% /
/dev/md2 683G 438G 211G 68% /home
I am now removing some files within my /home dir, and I see that the free space of the first partition increases (/)
Is there any correlation between files stored in /dev/md2 and /dev/md1 ?
Maybe inodes of /home files are stored within /dev/md1 ?
Basically MySQL is giving me many errors of "Got error 28 from storage engine" that means no more disk space is available.
The output of df -h is:
File system Dim. Usati Disp. Uso% Montato su
/dev/md1 10G 7,9G 1,6G 84% /
tmpfs 2,0G 0 2,0G 0% /lib/init/rw
udev 10M 176K 9,9M 2% /dev
tmpfs 2,0G 0 2,0G 0% /dev/shm
/dev/md2 683G 601G 48G 93% /home
Every filesystem here is not empty. Are there any other problem?
I am on
- a dedicated server (debian 64bit )
- and the errors happens doing an heavy query
I don't know what's happening but sometimes (pretty often in these last day) if i try to open my website (that is hosted on a my dedicated server)
the site takes too much time to show up. Then the only solution to recover it is to restart apache with the classic debian command:
/etc/init.d/apache2 restart
After that my website immediatly show up when I open it in my browser.
I have debian 64 bit with 4GB ram and a Core 2 Duo @ 2.33 GHz
Apache 2 settings are the follow:
Timeout 10
KeepAlive Off
<IfModule mpm_prefork_module>
StartServers 90
MinSpareServers 5
MaxSpareServers 20
ServerLimit 90
MaxClients 90
MaxRequestsPerChild 0
</IfModule>
Error.log shows nothing beside a "[error] favicon.ico not found"
Just after the restart top command is:

Please Help me. (and please don't ask me to install mod_status)
I saw /var/log/messages and i found a lot of this meessage, Maybe this is a DDOS attack?

My website runs on a dedicated Debian LAMP server . I would like to update the system (let's say I have a pretty old Debian version and I want to reinstall everything from scratch)
What strategy can I use to not have my website down while I am reinstalling everything?
Of course I know I can buy another server in the meanwhile and change the DNS whenever it's done. But this doubles my work.
Aren't some service that maybe can act as a proxy-cacher for a limited amount of time? Maybe what does CloudFlare but caching everything not just images.
This is pretty strange situation I am getting.
I have installed apc (with ./configure and make) on my LAMP gentoo with PHP 5.2.
To get apc loaded i need to place apc.so in my www php directory otherwise it just don't get loaded.
I don't even any idea of this, if you have even only tips please post an answer.
If you need the full series of command it's here: Failed installing APC?
I am trying to install APC on a gentoo with php 5.2 Here teh full command i Lanched:
mkdir /home/APC-php
cd /home/APC-php
wget http://pecl.php.net/get/APC
tar -xzvf APC
cd APC-3.1.9
/usr/local/php5/bin/phpize
./configure --enable-apc --enable-apc-mmap --with-php-config=/usr/local/php5/bin/php-config
make
make test (i think almost everything failed here)
make install
/etc/init.d/httpd restart
The make install command showed
Installing shared extensions: /usr/local/php5/lib/php/extensions/no-debug-non-zts-20060613/
Installing header files: /usr/local/php5/include/php/
When I did after make, make test the output was:

I already added extension=apc.so in /usr/local/lib64/php5/php.ini
The extension_dir is extension_dir = "./"
To make apc loaded I had to put the apc.so file in my www directory. Now phpinfo(); says it's loaded.
The problem is that apc_store doens't effectively store the data between requests.
$bar = 'BAR';
apc_store('foo', $bar);
var_dump(apc_fetch('foo'));
Within one request this work.
Now If i try to do a var_dump(apc_fetch('foo')); on another request it prints:
bool(false)
It is like APC isn't running in background but it starts only for each requests
Isn't this bounty worth the question? :(
My website is under attack. In this last 2 days I have identified and blocked ~20 IPs especially from China (and Taiwan, Malaysia, Egypt, Ireland, Spain and Russia)
This are some of the 20 ips:
95.74.78.55
222.124.156.230
113.108.166.57
125.41.130.120
115.64.76.208
210.5.147.148
117.139.54.192
118.100.12.250
58.251.109.127
61.50.164.157
217.217.131.108
41.236.224.217
151.82.45.148
Is there a way to understand why this is happening and maybe find who is the mandator?
These ip are requesting the same file thousands time/minute. I block one IP after it has made the 250th requests.
I have installed postfix with no config option.
I am trying to send email with php mail(); it works but it sends email with the default email of my dedicated server.
Are there anyway to tell postfix to follow the header set by mail function?
Thanks
$from='[email protected]';
$fromname='my Website';
mail($mailto,$subject,$text,'From: ' . $fromname . ' <'.$from.'>');
I want to install postfix (apt-get install postfix) to be able to send email thru php mail();
But i don't get does postfix needs an smtp to send emails or he can do it on his own? (because if it needs an smtp i can continue to use my PHPMailer or Swift Mailer)
I am on a dedicated server.

Is possibile that with a 5-10 settings for Min/Max Servers when i do top, there are tons of apache 2 processs??
Shouldn't they be only between 5-10? Just look at the 260 process sleeping O_O (d*mn apache)

Thanks for any explanation
(debian 6, lamp, 4gb ram)
I requested an hard reboot because none of ssh and http worked. Ping worked normally.
Which logs should i check to understand what was the problem?
Thanks! (debian 6 on lamp)

The cause is from 2 days ago:
look how the usage of swap goes +60% in less than 10hours
My control panel reports this as top 5 memory usage process:
If every apache2 process is 190MB large that sux because IF i do TOP i have 262 sleeping process most of them are apache2!

I have placed a .sh file that runs a php script weekly.
This script should run only once, but every sunday it runs at:
Any way to fix this?
in the first email the user agent that request that email via web is: [HTTP_USER_AGENT] => Lynx/2.8.5rel.1 libwww-FM/2.14 SSL-MM/1.4.1 GNUTLS/1.4.4
and guess who is the IP of the REQUEST ? it's the IP of my old server (where was setted the same cron job)
It's like the old server is requesting that cron via web, I just need to delete the cron job to my old server
Is there a configuration for this without installing 3rd party software?
I just typed a wrong password for login to ssh @ root.
I went to
/var/log/faillog
But the file is empty ( tho its filesize is: 32 Byte )
Ok in auth.log is spammed this:
reverse mapping checking getaddrinfo for dinamic-tigo186-180-143-166.tigo.com.co [186.180.143.166] failed - POSSIBLE BREAK-IN ATTEMPT!

What's that?
Someoen from china with two different ip is downloading the same big file from my server. Their ip are:
They requesting this file and downloading more than 20 times per minute.
What Can I do to prevent this? (I am on gentoo with root access)
And WHY they do this to a site that doesn't have nothing to do with china ?
ADD1:
Other ips:
ADD2:
the stupid thing is they are requesting only 1 single file lol. Or they want that file removed (tho i don't see why) Or they are pretty stupid
ADD3:
Situation is getting worse. IP are spreading from other countries too (usa and korea if www.geobytes.com/iplocator.htm it's right) And now they are requesting another file.
ADD4:
it seems after they realized i removed that file they stopped attacking me.
I will monitor the situation.
They started again after a sleep of 3-4 mintues with the same file (lucky me). Hard to say why this is happening
I am on debian 6.
Any way to see how many days are left before the cron weekly starts?
I am going to importi a database.. (db.sql)
I will use something like:
mysql -u root -p db < db.sql
Can you tell me what the difference is between this and mysqldump?
Thanks
I have a debian 6 at 64bit. I want install lamp. On some website i find:
apt-get install apache2
on some other:
apt-get install apache-mpm-prefork
Which one should I choose?
Thanks
I just bought a dedicated server with debian 6. I will install the classic LAMP.
Is there a way to make an image of the hard disk so in case of any problems I can restore this image?
Thanks
So I need a server that will host only 1 website. I will install debian as O.S.
I want to know: do I need to setup an user to do my stuff or, considering I will the only user of the server, I can use the root user to login via ssh and to do all my stuff?
Thanks for any suggestions, i am pretty new to this word.
