Max 240 People Online At The Same Time
Jan 15, 2007
I have dedicated server with a Swedish hosting company. We have a network/community website that can have about 300 people online at the same time. But as soon it gets to 240-280 people get logged out (Sessions are closed). The website becomes extremly slow.
What can we do to have at least 2000 people online at the same time with out any session being killed?
Do we have to upgrade the memory from 1 GB > 2 GB? Or do we need 10>100 Mb port? Unmetered server?

I'm not sure how many people here use VMWare, but I'll give this question a shot... I'm looking for a solution similar to Winrar that can view the contents of the .vmdk file. Either to extract any files, or just view the contents without having the have the virtual machine online. I checked Google as well as VMWare's forums/website with no avail.

I can't get access to a certain site. I always get the page with:
network time out - server at *** takes to long to respons. More people have noticed this and apparently it only happens to people with certain specific providers. And not all the time. Some times they DO get access eventy to they belong to the same ISP. So I guess an ISP isn't blocking access to it otherwise it would be permenantly/The site administrator insists that certain ISP's are blocking his site. He's hosting it on his own server. The domain belongs is registered at namecheap.com.
If an ISP is blocking this site (if that's possible?), that would lead to that 'network timeout' page wouldn't it?
What is the most likely reason for getting a timeout page anyway?

So I've just been browsing around and I've checked out a couple of peoples portfolios. Some of you guys have 100's of domain names registered under you waiting for someone to buy it.
So that's my question, how can you have so many domains registered? Isn't that very expensive?

I'm having my first DDOS attack. Do people DDos servers for no reason? Beacause they are attacking an IP on a server that have not had any sites or any use on it for 4 years.

I just switched to a new server last month and Im having a problem where a lot of my members and even some of my mods are unable to connect to my website. They are just getting a page cannot be displayed error. The website is ftascene(dot)com. Is everyone here able to connect to the site, and any idea why not everyone would be able to connect?

I recently moved a client of mine to a dedicated server with a hosting company called the NYNOC. After losing a few weeks of data for my client in the incedent described below, I am wondering if what happened was industry standard, or this was a case of choosing the wrong hosting company.
After signing up and paying the initial hosting charge, I received two notices - one on 18 july, and the second on 26th july - for a bill that was due 25th july.
On 2nd august I get a complaint from my client saying the website is down. I figured the hosting company had cut me off for a late bill. Fine, I figure i go and pay the bill and the reconnection charge and they put me back on.
After waiting 8 hours to get a support person (they dont have 24 hours customer service), I was told that I no longer had a account with them! No client log in. No server. Nothing. The disk was wiped clean and the server was sold to another customer. Without any warning that this would happen.
So my client lost a few weeks of customer data and I lost my credibility.
I was just wondering if this is standard practice in the dedicated hosting industry, or these guys are just bad news.
One more thing. When you talk to these people (they have only one customer support person) its almost as if they really really dislike their customers. As in, they talk down to you even as they exhibit complete disregard for your interests. This I know is not an industry standard. I have several accounts at Hurricane Electric, and they are tops. Unfortunately they do not offer well priced dedicated hosting.
I think I will try Interserver next. I spoke with one of the support guys on AOL late at night, and they seem good, and more importantly, are able to have a pleasant conversation with their customers.

I have a 777 cmod folder open. It needed to be writable so that legitimate users can upload their picture. However, i do not want people to upload .php or .php.pjepg etc to the server.
There are times that they do not use the form in my site to upload the php file. How can they do that? via perl command? And how to prevent such thing from happending?

Somebody knew password databases of my forum do not know how then enter and modify the forum style templates and add iframe codes. Among the actions of its currency, although that problem still:
Initially I found phpshell uploaded on my site and I delete him , and I realized that there is no other phpshell.
1- I have changed database password and ftp password.
2 - I coded config file using zend
3- I make chmod 751 for directory and 644 for files.
I worked all these actions, however hacked on a daily basis.
How come this hackers to my server?
How closed this issue?
What is the log files, which would know from which all the details from entering the database?

i have free hosting server and a rule to upload 3MB file max. it works for FTP, but somehow it doesn't work for php. It seems for php the limit on my server is 100MB (no idea why)
i use following directives to limit file size in php.ini :
; Maximum size of POST data that PHP will accept.
post_max_size = 4M
(4 just for some margin )
; Maximum allowed size for uploaded files.
upload_max_filesize = 3M
and i still can find 100MB files on disk. this is part of log file from apache from the account that uploaded it to me:
Code:
boorako.[] someip - - [13/May/2007:12:21:22 +0200]
"POST /a/redir.php?capthatag=accesscode&saveto=&path=/some/path/boorako.[]/a&comment=&domail=&email=&useproxy=
&proxy=&split=&method=tc&partSize=10&redirto=/a/index.php&link=redir.php?capthatag=accesscode&saveto=&path=
/some/path/boorako.[]/a&comment=&domail=&email=&useproxy=&proxy=&split=&method=tc&partSize=10&redirto=
/a/index.php&link=[url]
HTTP/1.1" 302 188
[url]
boorako.[] someip - - [13/May/2007:12:21:35 +0200]
"POST /a/redir.php?capthatag=accesscode&saveto=&path=/some/path/boorako.[]/a&comment=
&domail=&email=&useproxy=
&proxy=&split=&method=tc&partSize=10&redirto=/a/index.php&link=redir.php?capthatag=accesscode&saveto=&path=
/some/path/boorako.[]/a&comment=&domail=&email=&useproxy=&proxy=&split=&method=tc&partSize=10&redirto=
/a/index.php&link=[url]
HTTP/1.1" 302 188 [url]
"Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3"
as the effect of this (at least i think so), there was 100MB file in his home dir.
any idea how can he POST such big files even with those two directives?
i have also set LimitRequestBody to 5194304 and LimitXMLRequestBody to 5194304 in apache2.conf which also should stop files being POSTED as big as 100MB.
i have php 4.4.4-9, Linux Debian, apache 2.2.3 working in worker mpm, and php as fastcgi.
P.S. i removed server info like IP, dir and address to not show specifics about my server in public, i put [] there.

I installed mod_security and the 403security rules on my VPS (Centos 4.1, Release version of WHM).
Several vBulletin files, including the ajax quick editor and some vbulletin.org add-ons are triggering this rule and banning members' IPs in CSF:
# Restrict witch content encodings we accept.
#
# TODO Most applications support only two encodings for request bodies
# because that is all browsers know how to produce. If you are using
# automated tools to talk to the application you may be using other
# content types and would want to change the list of supported encodings.
#
# Note though that ModSecurity parses only three content encodings:
# application/x-www-form-urlencoded, multipart/form-data request and
# text/xml. The protection provided for any other type of encoding is
# inferior.
#
# TODO There are many applications that are not using multipart/form-data
# encoding (typically only used for file uploads). This content type
# can be disabled if not used.
#
# NOTE We allow any content type to be specified with GET or HEAD
# because some tools incorrectly supply content type information
# even when the body is not present. There is a rule further in
# the file to prevent GET and HEAD requests to have bodies to we're
# safe in that respect.
#
# NOTE Use of WebDAV requires "text/xml" content type.
#
# NOTE Philippe Bourcier (pbourcier AT citali DOT com) reports
# applications running on the PocketPC and AvantGo platforms use
# non-standard content types:
#
# M-Business iAnywhere application/x-mal-client-data
# UltraLite iAnywhere application/octet-stream
#
SecRule REQUEST_METHOD "!^(?:get|head|propfind|options)$"
"chain, t:lowercase, deny,log,auditlog,status:501,msg:'Request content encoding is not allowed by policy',id:'960010',severity:'4'"
SecRule REQUEST_HEADERS:Content-Type "!(?:^(?:application/x-www-form-urlencoded$|multipart/form-data;)|text/xml)"
I don't know how to decipher this rule to know if just removing it is ok, or if it is serving an important purpose. During a couple hour period it was enabled, that rule only seemed to trigger false alarms.
The above was triggered with calls such as [uri "/forums/ajax.php?do=usersearch"] and [uri "/forums/newreply.php?do=postreply&t=11057"]
What I really don't understand is that I have an .htaccess in place to turn off mod_security for the /forums directory:
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
I have also had this rule triggered today when someone tried to access : ...

I have a dedicated server specs: AMD 3500+ 64 Bit CPU, 1 GB Ram, 160 GB Sata Drive. For 1 month, CPU load average reaches 40-50 value. This happens about 5-6 times in a day. When I stop httpd service for 30 seconds everything goes normal. I think this is not a DoS attack because it comes systematic, I dont believe no one makes this regularly except bots.
Maybe its a system service or a cronjob but it stops when I turn off httpd service?
How can I be sure about what's making this regularly load?
I also did set up a script which mail me when load average of system goes crazy and restart httpd service. But instant restart is not working to stop load increase.

The server is going down from time to time, every 12 days or so the site hosted there is no longer accesible, everything starts with the site slowing don and down and then is not longer reachable, what we do is to request a power cycle, and with this we start all over again till next power cycle, so on so on, of course, here are my server details and more info on this:
- MySQL - 5.1.41-3ubuntu12.10
- Apache - 2.2.14-5ubuntu8.4
- PHP - 5.3.2-1ubuntu4.9
- operating system: Ubuntu Server 10.04 LTS
After some time emailing the support guys to barely check about what's going on, we received an email with a few things:
1.- found a few errors that likely would cause issues with Apache. The first error is:
[Mon Feb 04 05:03:10 2013] [error] mod_fcgid: fcgid process manager died, restarting the server and the next error is:
[Mon Feb 04 14:32:34 2013] [error] server reached MaxClients setting, consider raising the MaxClients setting ...
Both these errors seem to indicate that you have a process that is running out of control on your server. We were unable to determine what script on your site is running caused your connections to be maxed out however it does appear that before these errors were generated there was a WordPress plugin referenced in your access logs...
2.- Additionally during our review we did find that your error log for mercadodedinerousa.com is 45 GB's which is excessively large and can cause problems when Apache is trying to write a such a large file.
3.- The majority of the errors being logged are:
[Wed Feb 06 12:12:31 2013] [error] [client 200.76.90.5] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts/mercadodedinerousa.com/httpdocs/index.pl, referer: [URL]

Today I wanted to configure server for colocation and I went to both HP and DELL, and everything was ok until I started to configure HDDs. Price of regular 1Tb HDD is about $500 on both DELL and HP, while same drive costs $84 on newegg. Whats the catch? I mean processor, RAM, and everything else has normal prices, but HDDs are 6X more expensive than normal price.
Do you know any good site where I can configure server and order it to colocation address. Also it must be very cheap ? Best would be if I could order components from new egg, send them to company which assembles everything and then send it to DC.
