I run a dedicated server with WHM/cPanel (10.8.0).
I was recently supposed to update the Apache installation to add a module, but instead of clicking "load previous config" I clicked on "start build" by mistake. This brought the installation back to default.
I waited till the build was finished and then added all the modules I could remember having installed earlier. This made Apache not wanting to start. I went back to the default and then recompiled apache over and over again, adding 1 o 2 modules every time. Apache booted up fine, but for some reason my mail is suddenly acting up.
I keep getting the following error on one of my domain in my client:
Code:
Unable to connect to POP server mail.example.com.
Error sending password: -ERR Maildir invalid (no 'cur' directory)
When I click OK, I get:
Code:
Unable to connect to POP server mail.example.com.
Error sending password: Operation now in progress
I have a couple of other accounts in the mail client. None of them are receiving mails, even though I can see that there are new mails present in the mailbox via webmail.
My exim is configured to use mbox as far as I know. So I don't understand why I'm getting an invalid maildir message.
I got a new server online today with a fresh installation of centos and cPanel:
WHM 11.15.0 cPanel 11.18.1-R20683 CENTOS Enterprise 5 i686 on standard - WHM X v3.1.0
I have done the initial setup (ip's nameservers etc..) but when I try and run apache update I get the following:
Premature end of script headers: /usr/local/cpanel/whostmgr/docroot/cgi/easyapache.pl: Please check /usr/local/cpanel/logs/error_log for the exact error.
I look in the log file but it just repeatse the above error and doesnt supply any additional info.
i would like to update my CentOS Linux 5 but i don't want to update mysql and apache i need to use mysql 4. When i entered yum update i can see Total download size: 245 M i can see mysql i386 5.0.45-7.el5 base 4.1 M
how can update my server without updating mysql and apache
I update the sources.list on server 1 to mirrors of the new debian 4 etc . I run apt-get update and apt-get dist-upgrade . A whole bunch of things get updated (it was long time ago that I did this anyway). After some troubles with /boot/grub/menu.lst the server boots ok, and everything is well. This server used to have loads of 15-25 at peak times, but after the update its running very smooth with loads of 2-3 at the same peak times. I dont know why exactly, as I noticed updates in OS , kernel version (from 2.6.8x to 2.6.18) , apache2 , php (4.4.4-8+etch1) , and I also needed to update eaccelerator from 0.94 to 0.95 .
A few days later I update server 2. Everything seems to go the same, although the kernel version stays at 2.6.8-3-686. I dont think kernel version at start was exactly same at server 1. But the new php version is the same as server 1, and everything else looks the same too.
But when peak times are coming up, this server starts to have troubles. It is quickly rising to total of 200-300 processes , while server 1 always stays stable at 60-70.
Server 2 also reacts slow if I click somewhere on the site. It takes 5-10 seconds to show a new page. However the load stays pretty low at 1-2 . I see no big cpu usage and also no big memory usage. I have the impression that this server 2 is somehow wasting a lot of apache processes and is making things hard for itself without a real reason.
When I check the seperate mysql database server, I also notice a lot of processes.
Around 200-250 whereas it used to be 40-60. Sometimes this adds up so hard, that all webservers are blocked because mysql has too much processes. When I check the mysql connections, I see a few dozen things like 'unauthen ip:port Connect login' just hanging. All of them have the ip of webserver 2. Those extra apache processes are somehow hanging on to the mysql server without really doing something.
I dont know what is happening, but this server is underperforming very badly now. I managed to limit the problem by drastically lowering ServerLimit and MaxClients on webserver 2 , but this is no real solution. The server is still slow, at least now its not bringing down the others.
My question : what should I check for now ? I noticed a different structure in the conf files in debian etch, maybe something new has a bad influence on my old conf files? Is there something wrong with the combination of kernel+php version? I have no idea, please point me in the right direction so I can learn from this.
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] mod_digest_apple: Client is using a nonce not issued by this server for this context:/rb/Vorlesung/WS12/Downloads/, referer: http:<URL>

what is this? what ever i try to install i get this weird error..

I started a yum update on one of my VPS accounts. Halfway through the update I lost the connection to the server (Part of FDC's routing troubles...)
Now that FDC is back up and running smoothly, I logged in and when I do a yum update, it refreshes the repositories like it should, but then throws this error:
Quote:

Hopefully there's an easy way to go about fixing it..
I'm moving a site (Windows XP) from Apache 2.2 to the Apache Lounge server 2.4.9 under Windows 7.I exchanged httpd.exe and all modules and the server runs fine when I type localhost into the URL field of Firefox.But as soon as I type in the site name which I have assigned a VirtualHost to, I'm getting an Error 500 (Internal Server Error).
I am having a peculiar problem, when ever I attempt to access my server globally I get the dreaded 'No Data Received' error.
The machine is running Ubuntu 13.10 and is a dedicated server (I do not have GUI or physical access to the machine). All ports are open, iptables disabled, yet nothing works (running on port 80). I loaded the files onto a different computer at home and it works nicely, but not on the dedicated server.
Also, when the Apache server is off it says it can not connect in my browser, and when the server is on it says 'No Data Received' ...
how is it possible that after an update my main site is down? This site: www.orderhosting.it has plesk Panel and I have 20 sites. They work perfectly but my main site is off. I think there is an error in the configuration because:
This is strange.Error log does not report any errors, only this: [warn] RSA server certificate CommonName (CN) `Parallels Panel' does NOT match server name!?
We have a VPS system running with Plesk but after a nightly automatic update there was a error message in Plesk, with a link to 'fix' the problem. After that Plesk stopped functioning. Now, when we log in with correct credentials (we know its correct because we if incorrect, we get a message its incorrect, so thats working) we're presented with this error:
Error: Call to a member function getName() on a non-object (MainMenu.php:48).
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?
I am using user authentication with the following components:
Apache/2.4.10 (Win32) + mod_auth_basic + mod_authn_dbd + mod_dbd + ODBC Driver + Microsoft SQL Server 2008(SP3).
It works fine except when I do not provide any username when browser asks for username and password. In this case I receive the "Internal Server Error" as the response instead of "Unauthorized" response.
The most interesting part of the error.log is:
[Sat Sep 27 21:23:17.639860 2014] [authn_dbd:error] [pid 1208:tid 1636] [client 127.0.0.1:1363] AH01656: Query execution error looking up '' in database [[dbd_odbc] SQLBindParameter returned SQL_ERROR (-1) at apr_dbd_odbc.c:604 [Microsoft][ODBC SQL Server Driver]Invalid precision value HY104 ]
The AuthDBDUserPWQuery directive in my httpd.conf is:
AuthDBDUserPWQuery "SELECT password FROM member WHERE CONVERT(VARCHAR(10), member_Index) = %s"
And the member_Index column in the database is smallint.
We are currently using Apache 2.2.10 as the reverse proxy for the SAP portal server 7.3.1. The SAP applications are built based on webdynpro abap technology.2 of the apps are getting intermittent spinning circles. The Apache server will ultimately timeout and give the "bad request" and HTTP 400. We were never able to reproduce the problem except we do see users are running into them. Obviously, the problems occur very randomly, but often enough to generate a lot of support tickets. No error was generated in the sap system log.
Here is what I see from the apache access log and error log:

I found bug 37770 and went to see the apache admin. But he thinks that the parameter(proxy-initial-not-pooled=1) that fixes the bug only applies to mod_proxy_http. However, we are using mod_proxy.
There was an error sending your message: Failed to connect to localhost:25 [SMTP: Failed to connect socket: Connection refused (code: -1, response: )]
I got that error everytime I try to use mails using horde, this is happening since the last cpanel v11 R update... any ideas about how to fix this.. i couldnt find anything at cpanel logs...
Using mail clients or squirrelmail works perfect, im using RHES 4.
I have just updated to plesk 12 and I am having an issue with all of my web pages returning a 404 error, I can connect to the SQL databases and FTP it is just loading the web pages.
Plesk recently attempted to do an auto-update and it failed. I have not been able to get it to update since. When I connect using SSH, and try to do a manual yum update I get the following error:
Code: Loaded plugins: fastestmirror Setting up Update Process Loading mirror speeds from cached hostfile epel/metalink | 13 kB 00:00 Traceback (most recent call last): File "/usr/bin/yum", line 29, in <module>
