CSF Causing Server Ping Timeout
Jul 28, 2008
I just installed a fresh new server with CSF
Soon I find out that my ping keeps dropping. The server was smoothly running, SSH is smooth, Website are loading fine, except I cannot ping my server. I disable SELINUX completely and it still doesn't help.
When I disable CSF, my server ping are responding back!
So I remove CSF installation and reinstall CSF, the same problem appear
How can I solve this issue?
My kernel is 2.6.18-92.1.6.el5PAE running on latest version of cPanel on CentOS 5.1

globichen can explain about this.
ping timeout happen frequently.
this is the 2nd time happen in a week
i've submit a ticket regarding about this
customer service replies with server is online.
i'm not bashing their service but frequently ping timeout really makes my business down lately.
Loading website takes a few min & even couldn't access to server due to ping timeout.

For some reason, my IPs that we use for a IP based site are un-pinable (ping time out) after some time. However, when I restart apf (firewall) the ip are back again and are pinable again.
We added the IPs for the IP based site over the ensim panel.
I belive its a Firewall issue, does anyone know how to check why the Ips are always getting un-pinable?

Which you think is still acceptable for a website?

I'm having a very intermittent PHP error on my dual processor CPanel/CentOS 4x box. And it happens randomly across several domains, so I know it's not a single domain problem.
I can never figure out what causes it. 95% of the time the sites work fine (no error), but ever so often my php includes give me something like this:
PHP randomly fails to find the directory/file. And it requires an Apache restart to make it work smoothly again. It will be fine for a few days, but then it happens again. So I suppose it may not be directly related to PHP, but more of a server/apache issue? Any ideas at all?

Ever since Monday morning, my site has had problems because the server at my host is under attack.
Most of Monday my site was down. Then Monday late afternoon, it came back...I thought. The forum is up and running, but the rest of the site, built on WordPress, is screwy.
Most of the plugins aren't working because of inability to connect with the database.
I can't log in to my cPanel at all and haven't been able to since Sunday.
This is the first time I've experienced anything like this, lasting this long.
It has me wondering if I should start considering a new host. I have loved their service, especially their speedy support (native English speaking to boot) so I hate to leave but I'm not sure if their service is going a little downhill or not.

For the past few days, one of the server is causing a bandwidth utilization surge for the entire rack on almost daily basis. It happen for a few minutes and it went off then it will be the same thing again the next day. When the surge is happening, most of the servers on the same segment will be inaccessible for the few minutes.
The bandwidth utilization graph for my rack is recording an abnormal surge from (6mbps --> 90mbps) for the few minutes. My MRTG is showing 2 of the Plesk servers giving the problem but the NOC guys said it the Cpanel that causing the problem.
I tried logging in to both servers but could not find what's the cause for this.

It's been a while since I've posted in this area of the forum, but was just wondering if by now someone or some company has developed a script/software that you can install on your server that will tell you the exact area where the high CPU load is coming from, such as from someone sending email, a certain users account, and etc?
Most times, you have to be mointoring your server at the time of the high load to be exactly sure of what is causing the high load, so, I'm talking about something that will email you right on the spot of the high load in case you are away and will know what caused it.
Most I've seen only tell you that you have a high load, but don't tell you what exactly caused it.

My host has suspended saying my server was overloaded and sent me a log to my mail and i don't have access to cpanel also. I just have a wordpress blog and when i had contacted host through chat they told some ip might be causing this issue so ban that ip when ur account is unsuspended.
But i am really unaware of how to find which ip is causing this issue as i have little knowledge on analysing logs. Any help regarding this is highly appreciated and please leave your suggestions for me.
I am pasting the logs that were sent by host to me in mail:

I have 2 CPanel servers. I wanted to transfer multiple accounts via WHM but it gives me error that I cannot SSH into the other server.
I tried to ping the 2nd server from 1st server and it gives me:
root@s [~]# ping xxx.xxx.xxx.7
PING xxx.xxx.xxx.7 (xxx.xxx.xxx.7) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted

I added both server IP into allowed list inside my APF firewall on each server as well.
I rebooted both server earlier before, but it is still not solving my problem.

So I'm wondering what if anything I can do to get a better ping from my 1and1 server.
It's located in Wayne, PA and my ping floats around 70ms and I'm in South Lake Tahoe, CA. I only ask because there are servers with Peer1 hosted in New York, NY that give me a ping around 20ms.
Thanks for any help or advice.
Its a Windows Server 2008 Web Box.

So load under 1, almost no hard drive access, why is the ping so high?

- Apache version : 2.2.21
- operating system : MAC OS Lion Server
- mod_ssl : 2.2.21
I have a certain area on a homepage which is protected by an .htaccess file. The code of the .htaccess file is the following:
Code:
AuthType Digest
AuthName "Password Required"
Options +Indexes
# code for HTTPS
RewriteEngine On
RewriteCond
%{SERVER_PORT} !^443$
RewriteRule (.*) https://%{SERVER_NAME}%{REQUEST_URI}
Require valid-user
Usually everything has been working fine with this .htaccess-file until today. There hasn't been any change on the system.
If you click on the hyperlink to the restricted area the login window appears where you need to type in your username and a password. After typing in these data the following message appears in the browser:
500 Internal Server Error
The server encountered an internal error or
misconfigruation and was unable to complete your request. (…)
The apache error log file contains the following message:
Request exceeded the limit of 10 sub request nesting levels due to probable configuration error.
Use 'LimitInternalRecursion' to increase the limit if necessary.
Use 'LogLevel debug' to get a backtrace.
The increase of the LimitInternalRecursion does not solve the problem. So I switched the LogLevel in the httpd.conf file from warn to debug and looked again on the entries of the error log.
The following appeared (I have replaced ip addresses, usernames and URL by xyz or <URL>) :
Code:
[error] [client xyz]

I have a problem with one of my domain. Some users around the world cannot access the website, but they can ping and traceroute the server without any problems. I am able to access the website perfectly.
Site URL is www.djluv.in
And we are using IPB 2.2
Moreover if theres another domain on the same server, they can access it.
There are about 25-30 users who are facing this problem, but from different part of the world so I cant even say ISP problem.
APF has been shutdown, no Ban Filters on IPB or cpanel.
What are the possible reasons why they couldn't access the website? how to fix the problem?

I am running Plesk Version: 12.0.18 on CentOS.Earlier today my service provider had a massive issue and my server was down for several hours. Upon it being back online i've restarted but now I cannot load any of my pages. I have 10 domains setup and if I ping their name servers or the server IP i get packets received now.
One of my installed domains is [URL] ... now if you try and load this url you get a time out but if you try to access admin page URL....None of the subscriptions are able to load their websites when i type in their URL and well it worked before it went down.

I'm having a very odd problem with one of my Linux (CentOS) cpanel server, all the server's services (http, ssh, mail, dns, etc) stop responding but the server still responds to ping.
I can't find anything wrong at all on the log files either, and the technicians that manually restart the server have told me that there is no indication of a problem on the screen.
I suspected a hardware issue and had the data center techs run a hardware test on the server but everything cleared ok.
This issue started a couple of weeks ago, no major upgrade or install took place when it started happening. From what i can see the halts are completely random, some times it goes for days without it happening and some times it happens just hours after the reboots.
