# Of Apache Requests - Modify
Feb 8, 2007
I have a dedicated box with softlayer and I have noticed at varying times the past few months that with sites we host, sometimes the connection times out (I'll try to access like 5 or 6 sites within 30 seconds or so and they all drop, then a minute later they load fine).
I opened a support ticket and they said it usually has to do with the # of requests Apache can handle, and that this can be modified. They stated they could: "tweak the apache configuration file in this server that can make it possible to handle more requests."
So my question is what should the # of requests be set to? (I'm not sure what it is now, but I assume whatever the default # is).

I have WHM and Cpanel on my dedicated server. Is there a way to give them access to change this? I dont want then to have access to everything either.
Edit your httpd.conf file.

I have been experiencing a lot of Keepalive requests for a particular image on a particular domain. please see the lines below.

These are just a few lines from the top.
How can i prevent this from happening.. it seems as a SYN Flood, or maybe a DDoS.

We have an Apache acting as a reverse-proxy and listening on the Internet ("Our URL" on port 443).
We would have two ways of accessing this reverse-proxy:
-From a mobile app (authentication would be based on a corporate certificate)
-From any browser (authentication would be a login form)
The question is: can Apache forward requests to either server 1 or server 2, depending on whether a certificate is sent by the client?

I have Apache 2.4.2, OpenSSL/1.0.1c, on Windows Web Server 2008 R2 (64 bits)
After 12 hours of heavier load, the SSL requests stopped working/being answered. However if you requested the same page via http instead of https, it worked fine. Restarting the Apache server fixes this, for a while. Again after a few hours of traffic, the https requests stopped working again. I checked the logs, and nothing notable, the mod_ssl entries just...
The site is called only by client developed with Delphi 2007 (CodeGear user-agent). Delphi client use THTTPRIO for sending HTTPS request to SOAP.

So I just upgraded Apache 2.2.22 to Apache 2.4.3 and made sure to go through all the options that had changed and update the conf file accordingly. This included adding the cache module for SSL and changing the SSLMutex option over to Mutex default ssl-cache. We also turned off SSLCompression due to the CRIME attack vulnerability.
We use apache strictly as a loadbalancer to 2 tomcat servers via mod_jk. Apache serves no static content at this time.
After being deployed, everything worked fine until later in the day. After 3 hours of heavier load (our site only takes significant traffic during business hours), the SSL requests stopped working/being answered. However if you requested the same page via http instead of https, it worked fine.
Restarting the Apache server fixes this, for a while. Again after a few hours of traffic, the https requests stopped working again. This time I turned the loglevel up to debug and restarted the Apache server.
As traffic slowed down it took another 6 or 7 hours before SSL requests stopped working again. I checked the logs, and nothing notable, the mod_ssl entries just... stopped. (I don't know for sure its ammount of traffic related, it just seems that way)
I have tried reproducing this in a lab, but have not been able to get it to happen on the lab server.
OS: Windows Server 2008 R2
Apache: 2.4.3 vc9 build with OpenSSL 0.9.8 downloaded from apachelounge.org
Mod_JK Version 1.2.37 vc9 also downloaded from apachelounge.

I've spent the last several months working on a huge upgrade of a couple dozen websites. The upgrades include modifying Apache so that visitors who arrive at links pointing to mysite/World/New_York are redirected to mysite/world/new-york. In other words, all my links now default to lower case, and underscores are replaced with dashes.
Unfortunately, publishing it has been an endless series of disasters. My websites are now all crashed, and the server is unbelievably slow. It takes pages forever to load (if they load at all), and I can scarcely publish files online.So the following notice sent to me by my webhost got my attention.
IT appears your own server IP is making GET requests to Apache, causing excessive loading and causing service failures. On today's date, your IP made almost 6,000 connections to Apache:<br><br>
[root@host ~]# grep 64.91.229.106 /usr/local/apache/domlogs/mysite.org | wc -l 5924 [root@host ~]#<br><br>
These were all the same request:<br><br>
64.91.229.106 - - [12/Apr/2014:08:10:10 -0400] "GET /404.php HTTP/1.0" 200 14294 "-" "-"<br><br>
And that made up the total of requests:<br><br>
[root@host ~]# grep 64.91.229.106 /usr/local/apache/domlogs/mysite.org | grep "GET /404.php HTTP/1.0" | wc -l 5924 [root@host ~]#<br><br>

I have a little problem (on my Raspberry) with the maximum concurrent connections.When I open multiple tabs of a webpage which keeps persistent connections, apache is unable to serve more requests.Here is the (shortened) mod_info output (which also takes some time till there is a process kind enough to serve the request):
Code:
Server Version: Apache/2.4.10 (Raspbian) OpenSSL/1.0.1k
Server MPM: prefork
5 requests currently being processed, 9 idle workers
.___W____WWW_..W_...............................................
................................................................
......................
Srv PID Acc M CPU SS Req Conn Child Slot Client VHost Request
[Code] ....
When I understood it correctly, apache should spawn new processes (up to MaxRequestWorkers=150)
But there are idle???? processes, so it wont add new ones?
I dont think it has to do with mod_proxy (used for the webpage) since the mod_info output is affected as well...

A weird thing happents once on few days on my server, and it's not a regular thing or on exact time.
When I have this problem no page can be loaded in the browser, but WHM is working, i think because it's accessed by IP .
In apache status page I can see lots of ..reading.. requests which are there even for 10 - 20 seconds sometimes.
Usualy the server has 10 - 20 requests/s :
CPU Usage: u35146 s2297.05 cu2.74 cs4.5 - 6.97% CPU load
11.2 requests/sec - 83.0 kB/second - 7.4 kB/request
10 requests currently being processed, 8 idle servers
But when the ..reading.. requests appear it goes much higher like 100 to 200
11.5 requests/sec - 85.3 kB/second - 7.5 kB/request
200 requests currently being processed, 0 idle servers
after 3 minutes :
160 requests currently being processed, 30 idle servers
When I logged on to SSH I saw that there are ~150 conection from a single IP .

I have an Apache Server (2.4.3) and a Tomcat Server (7.0.36) and have some Java Applications deployed.Everything works fine, but when we start a quite long Ajax process, I see in my Java Application, that a Ajax request is received and starts processing - everything fine. But during processing of the first request, I see a second request starts after 5 minutes.

I currently have a web VPS hosted with FDCServers.net and after 5 days of switching to it i am getting massive HTTP requests. When i login to WHM and hit apache status i have many requests per second by multiple IP's that are going to pages that simple don't exist. Currently my hostname for the server is set at web-01.optical-hosting.com which is what the requests are being sent to. I am also having a DNS issue because when i put http://web-01.optical-hosting.com in the web browser it displays the first account's site under "list accounts" in cpanel. Can someone please help me fix both of these issue's? i will post an apache log in a second post as it is long. Also, these are from overseas. please someone help me with this i have Aim and Msn.

My Linux Server's Http Daemon (Apache) would stop serving websites ever so often, as soon as apache is restarted the error fixes iteself only to resurface within few hours.
The apache process would still be running i.e. apache does not die but no websites hosted on my server would be accessible from browser. And when this happens the apache logs do not log any http requests.
Instead when this happens all http requests to my server would be redirected to some weird Trojan website and my Norton Antivirus would show an Alert/Warning, for example;
"Browser exploit at www.xxx.xxx was blocked"
Risk Name: MSIE WebViewFolderIcon ActiveX Control BO
or another error like;
"Auto-Protect has detected Trojan.Fakeavalert".
At first i thought the problem could be with my Laptop/ISP so i logged on to the server via SSH and opened try to open a website using command line "lynx mywebsite.com" and it shows following error;
"Alert!: HTTP/1.0 503 Service Unavailable".
Now if i assume my laptop were to be infected, then as soon as i restart my apache and visit mywebsite.com eveything returns to normal with no such warnings. Why do i see those norton error messages only when apache is down with 503, and when apache is down with 503 how come the http requests always get redirected to some suspicious websites and nothing gets logged in apache error log?
I think my server is being attacked causing http to get unresponsive and thereafter http requests to my server are redirected to some malicious website, is this correct?
Also, i suspect this is a php script exploit as some customers have reported that google have blocked their website due to security reasons, i found <iframe> tage inserted in some php pages which i fixed.
Also, another thinh i noticed;
when apache responds with the 503 it is referencing PHP 5.1.4 in the header response:
[root@]# curl -I xxx.xxx.xxx.xxx (my server ip)
HTTP/1.0 503 Service Unavailable
Server: Apache
X-Powered-By: PHP/5.1.4
Retry-After: 20
I am running PHP 4.3.9m why does apache responds with PHP 5.1.4 when this 503 error surfaces?
Also, since my apache was dowan with 503 error a customer mailed in today saying;
"It seems that my site www.xxxx.com is regularly down, and the winlogon virus is involved."
I suspect this is again due to the fact that http requests start getting redirected?

So I've got a problem where a small percentage of incoming requests are resulting in "400 bad request" errors and I could really use some input. At first I thought they were just caused by malicious spiders, scrapers, etc. but they seem to be legitimate requests.
I'm running Apache 2.2.15 and mod_perl2.
The first thing I did was turn on mod_logio and interestingly enough, for every request where this happens the request headers are between 8000-9000 bytes, whereas with most requests it's under 1000. Hmm.
There are a lot of cookies being set, and it's happening across all browsers and operating systems, so I assumed it had to be related to bad or "corrupted" cookies somehow - but it's not.
I added "%{Cookie}i" to my LogFormat directive hoping that would provide some clues, but as it turns out half the time the 400 error is returned the client doesn't even have a cookie. Darn.
Next I fired up mod_log_forensic hoping to be able to see ALL the request headers, but as luck would have it nothing is logged when it happens. I guess Apache is returning the 400 error before the forensic module gets to do its logging?
By the way, when this happens I see this in the error log:
request failed: error reading the headers
To me this says Apache doesn't like something about the raw incoming request, rather than a problem with our rewriting, etc. Or am I misunderstanding the error?
I'm at a loss where to go from here. Is there some other way that I can easily see all the request headers? I feel like that's the only thing that will possibly provide a clue as to what's going on.

I have been trying to solve a big problem for the last 2 weeks with one of our servers.
The client using our system (web based w/ apache and php) is a contact center firm. They have about 120 operators, all connect to our websever with the same IP.
We have been suffering DoS attacks from some of these operators. This are simple, browser attacks , namely 5 or 10 operators will just hold F5 key and bombard the server with requests when they shouldnt.
We did manage to produce a php protection which will recognize the multiple requests and blacklist the user, but its "too late" because the request have already been sent and processed by the webserver.
We use the user ID in the system to control who should be blacklisted, so this is all dependent on our own authentication.
Ideally, we need something EXACTLY like mod_evasive, but for rejecting single requests instead of blocking the IP. Exemplifying : if a user calls the same url, 5 times, in a 3 second spawn, we will reject every next request for 30 seconds, but only the requests by that user.
If the webserver can make any use of it, the user id is stored in a cookie.

I'm running Apache 2.4.4 on Windows Server 2008 R2. It's already happened many times that Apache stopped responding to requests. The last entry in the error.log:

I'm trying to prevent unnecessary GET requests from being processed by my CMS that originate from mutating IP address locations. This is sucking up server resources when the request is processed by the app, and so if possible, I'd like to block them with HTACCESS so that the request is stopped before anything is intensively-processed.
What happens is that an IP address will make a GET request for, say, "blah/test" or "blah/test2" but nothing else (no site assets like images or CSS/JavaScript files or even other pages). After this request, another IP address will then make an equivalent kind of request, and so on, and so on... All of them have similar if not identical user agent strings but they're always worthless requests that do nothing but waste CPU and RAM. I'm assuming it's just some idiotic SPAM bot because of this.

I've just run upon a problem while trying to go into my phpMyadmin from within my MySQL Databases icon.
When I try to log into phpMyadmin I get this message:
Quote:
"This feature is not available while logged in with root override. You are logged in with the root, or reseller's password. Please login with this user's account password."
Also, as soon as I log into cPanel I receive a red "Warning: You are logged in using the reseller or root password." Yes, I am logging into the only account I have.
When logging in with the initial account I created I can view the MySQL dbs that I have created, but I don't have access to phpMyadmin - I get that error message. This is new because for the last two weeks - about as long as I've had this server - I have had no problem even signing in with the same user id and password. Suddenly it won't let me in.
So what do I need to do?
I created a new account, but I can't see my MySQL dbs with that new account.
I don't know how to modify my one existing account so that I can access phpMyadmin.
Any thoughts? I hope I've been clear.

Applying Plesk firewall changes? I make my change, apply and get to:
Status: Applying in progress. If your browser shows connection error messages, or if this screen does not disappear in more than 30 seconds, go to previous page.
And there things stay. Going back to look at the firewall I can see the change haven't been applied, and going to apply just results in the same. No error, just no anything. It also took numerous attempts to get firewall modification to be swtich on although finally at about the eighth attempt changes were enabled. Only now I can't apply them ...
