We're trying to optimize the speed of our website. It's hosted on its own box.
We're looking for software that will monitor/aggregate the time it takes for certain requests -- For example, we would like to see which files it takes the longest to serve.
Is there server-side software that will take care of this?
Linux/Apache/PHP/SQL
I honestly dont understand why does DELL, HP and others price their 1U TFT monitors at 3 times the cost of the cheapest laptop?
I mean, dont get me wrong, I am all for spending good money to get quality products but I feel very awkward spending 3 times as much for a screen and keyboard when I can get their laptops WITH OS, MEMORY AND HDD for 3 times as less and use it as the 1U TFT monitors.
I can get a powerful server from Dell and HP at that price for crying out loud.
But then again, I might be seriously overlooking something here because what justifies such high price?
I've heard of software that notifies the root admin when physical components in the server are slowing down and are about to die (such as hard drive, processor, memory, etc). It gives you advanced notice that you need to replace a server's component before the component fails. It helps in keeping downtime to a minimum.
What is this software called and are there any available that you know of? What has been your experience with such software? Looking for both free and paid software. If anyone knows anything about this,
I am having some serious speed issues with my 1Gbit server at FDC. After opening a ticket, they've simply dismissed it as a server configuration problem. However I am convinced it isn't because certain ISP's (usually universities) get good speeds, usually 700kb/sec but the vast majority of my users get between 20-50 kb/sec and it's causing a lot of complaints.
Furthermore I have other servers with FDC which are 100mbit which perform better than my 1 Gbit one. There are no server bottlenecks (CPU/RAM/HDD), since I've closely monitored them (PRTG) and they aren't even heavily utilised. So the problem is with the network at some point.

where abouts you are downloading from, your ISP and net connection. Wget's from servers are also welcome as are traceroutes.
I block them in htaccess but their repeated attacks is making my server load crazy.
I installed AFP but it doesn't do anything, where do I set rules on automatic blocking?
I set up a cron to run every minute & I'm running a PHP script by way of cron like
wget http://example.com/some_script.php
Now does each request of Cron is a seperate HTTP Request or what? Say my script takes more than 1 minute to execute completely but before its completed, its called again. So, will that effect the PHP script running because of previous HTTP Request or will it create a new HTTP Request & let the previous request finish its operation? Technically, it shouldn't block/affect the previous request, but I'm not sure!!
Should I block ping request to my servers from WAN?

I observed too many http requests into the server, so just wonder how your guys twaek server to accept over 1000 request and more?
if there is a rule to add to firewall or mod_security to ban any IP which is sending more xx number of POST requests to the same URL?

what is happening here, as this looks to be something dodgy.
I have a guy who can't get to any of the 100 or so virtual hosts on my RHEL3 server.
It's running the latest Apache RPM from RedHat. I also have mod_evasive and mod_security running.
Here's what I know. The guy *CAN* connect via SSH and FTP. The guy *CAN* see the default web page when he hits the IP in his web browser (e.g. he types [url]into the address bar on IE). But when he uses any of the host names on the server he *CAN NOT* see anything. He gets timeout errors.
His IP in NOT in ANY error logs, it's not in mod_evasive or mod_security, it's not in IPTABLES, it's not anywhere I can see.
I must be missing something. Anyone have any ideas?
What would be in front of Apache blocking his requests?
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 a Qmail server that is using relays.ordb.org
As you probaly know this shut down two years ago. But is now sending all requests as spam. No one is recieving there emails.
this a Standard Qmail,with a hacked qmail-send witch intergrates with Mysqld.
is not installed with qmailroks, or supervise. Can't find the config text file.
how can we remove traces or referrences to relays ordb.org
I am getting a lot of GET requests from different IPs to 4 nonexistent PHP files on my server. Is there any way to block the requests to avoid the resources use of apache that these requests are generating?
I have installed mod_security but Im not sure about how the block rule should be.
The requests are going to images/log.php, images/log2.php, images/log3.php and images/logi.php of one of the sites hosted on the server, is there any way to block there requests for a specific domain or path?
I have been experiencing a lot of Keepalive requests for a particular image on a particular domain. please see the lines below.

How can i prevent this from happening.. it seems as a SYN Flood, or maybe a DDoS.
I maintain Java servlet applications on my hosting platform [hosting-q.com] and access the applications from another site [wiredpages.qisoftware.com]. Today, there was a demand problem which caused the hosting server to block access to requests from the other domain.
Do you know if there is an .htaccess directive that can perform this blocking or some sort of system trigger?
The thing is-- only the servlets requested from the external domain and not requests from the originating domain [or hosting domain] were blocked.
There seems to be some problem with my server, none of the websites hosted on my server are accessible, the http requests either return a blank page or a page with a red quare on the upper left hand corner.
I am not sure if this is some kind of infection or DNS problem or a problem with memory apache is taking up
as i have thousands of virtualhost entries in my access log accumulated over the years out of which only a few 100 websites i am serving presently, but never deleted the non-exitent virtualhost blocks.
At times the websites are opening but most of the times they are not. And when they do not open my http requets are not logged in apacha access log.
Even the customers have reported the same problem.
Also, just four days back i had a strange issue where all
http requests to my server would take me to [url].
I can SSH to server, and everything else is working fine.
I just went with Steadcom's VPS and they are great. I am setting things up and it's going pretty well, I have to dust off my linux/server knowledge that I haven't used in a couple of years.
Anyway I'm creating a virtual host.. I will have about 10 in the end, but right now I only have one domain IP Pointing to my new server. My registrar is NamesDirect.
When I create the virtual host, I can no longer access subdirectories directly. My Virtual Host directory is, say, /var/www/html/newdir
If I try to reach http://www.domainname.com which has been configued as a virtual host, that comes up correctly from the directory /var/www/html/newdir and works fine.
But if I try to reach http://myipaddress/newdir I get a 404 page not found error. Looking at the log, it's trying to reach /var/www/html/newdir/newdir so it's putting in the virtual host redirect even for just hitting the subdirectory directly.
Is this normal? Do I have something configured wrong? I have another domain that I have changed to IP Point to the VPS but until it propogates I won't be able to test having 2 virtual hosts.
Also.. I have not set up DNS on my VPS. I don't really understand it, and IP Pointing has always worked for me when I ran my own server form my home so I was just going to do that. But I wonder if this could be one of the problems.
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...
I host my DNS with DNSmadeeasy.com , I noticed that I have daily more than 350.000 DNS requests for main domain, This domains got about 80.000 uniqes/day, so this is strange how can there be 350.000 DNS requests/day. Seems that I'll go over the quota because of this.
The TTL for all domains is set to 86400.
Is there a way to discover how its possible ? And also is there a way to do something to make this number lower (DNS requests)
It has been 4 days now from the date i requested there is just silence from eboundhost, looks like they are planing on renewing my account and charging my card? what should i do? cancel the credit card and report them to BBB?
View 14 Replies View RelatedA 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 .
Where is a server's IP address for outgoing requests set? e.g. if a script on the server fetches ip-address.com, the IP that is identified there. A server may have multiple IPs pointing to it, but there's only one that outgoing requests are funneled through. I've tried changing "Main Shared IP" in WHM, but that doesn't seem to affect this.
Is this set server-side, in some setting file - or is this a datacenter thing?
