mod_fcgid is crashing apache windows and linux

Posted on by mario

With apache 2.3.15 I had kinda  the same issue with mod_fcgidon ubuntu 8.04 as on windows.  With -k restart or -k graceful the server did not die like on windows, but the server delivered than only a 200 OK response header, but nothing more. Switching from worker mpm to event mpm seemed to solve this, but the server died later :-/

Since it has talmost the same issues like on windows I could make a patch that fixes this. Grab the patch (patched against trunk) for the patch for 2.3.6

The bug 50309 is now longer than a year listet. Bad that none applied it yet.

Secure apache against CVE-2011-3389 aka Beast attack

Posted on by mario

During the summer rumours about a new attack against SSL started circulating (CVE-2011-3389).
As it turns out, the attack itself was conceived years ago, deemed impractical, but it was nevertheless fixed in TLS 1.1. The new attack technique introduced a few optimizations to make it practical.

In terms of mitigation, I expect this problem will be largely addressed on the client side, despite a potential compatibility problem that may cause some TLS sites to stop working.

With this config you can avoid that attack.

SSLProtocol all -SSLv2
SSLHonorCipherOrder On
SSLCipherSuite ECDHE-RSA-AES256-SHA384:AES256-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM:!SSLV2:!eNULL

#NO Longer needed cause since IE 7 this works ;) 
#SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown

With OpenSSL 1.0.1 it must be

SSLCipherSuite ECDHE-RSA-AES128-SHA256:AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH

vserver ubuntu IPv6 network

Posted on by mario

Since some days there is IPv6 available for my server. But I noticed it just today. Editing /etc/network/interfaces and adding a new virtual interface didn’t work at all. The /etc/init.d/networking restart just showed errors. And ifconfig venet0 wasn’t satisfying.

What works is /etc/network/interfaces just adding the loopbback

iface lo inet6 loopback
        adress ::1
        netmask 128
        gateway fe80::1

Now the trick is to add /etc/rc.local and add this before exit 0

ip addr add 2a01:238:40ab:cd12:dead:beef:dead:beef/128 dev venet0
ip route add default via fe80::1 dev venet0

Than execute /etc/rc.local
Wonder o wonder. Ifconfig works and also ping6 ipv6.example.com

Than I had to add the new ipv6 adress to my apache config

Listen [2a01:238:40ab:cd12:dead:beef:dead:beef]:80

Don’t forget a to create a symlink from rc.local to /etc/rc2.d/S21rc2.local

Apache AJP reverse proxy

Posted on by mario

With apache it is possible to have a reverse proxy with AJP instead of http. With the use of mod_proxy_ajp it is very simple to set up and faster than just plain http protocol

<VirtualHost *:80>
    ServerName jenkins
    DocumentRoot "/mario/Apache22/htdocs"
    <Directory "/mario/Apache22/htdocs">
        Options Indexes Includes FollowSymLinks
        AllowOverride All
        Order Allow,Deny
        Allow from all
        Deny from none
    </Directory>
    <Location />
        ProxyPass ajp://localhost:8009/
        ProxyPassReverse ajp://localhost:8009/
    </Location>

    SetEnv vhostname jenkins
    Header add X-Server-Name %{vhostname}e
</virtualhost>

Than start the backend server, in this case only with AJP and listen only on localhost

java -jar jenkins.war --httpPort=-1 --ajp13ListenAddress=127.0.0.1

Zend framework lucene UTF-8 problem

Posted on by mario

I had issues with the zend framework and its implementation of lucene. It saved the values from my UTF-8 database in the lucene files with characters like UTF-8 in ISO 8859-1 like on the search result page. And I wasn’t able to search case insensitive.

I noticed that the apache header (zend server CE) wasn’t sending UTF-8. So I added AddDefaultCharset utf-8 to my httpd.conf. Didn’t help.

What helped: In the Bootstrap.php adding to the init of the search

Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8());
Zend_Search_Lucene_Search_QueryParser::setDefaultEncoding('utf-8');
Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8_CaseInsensitive());

In the model it is needed to decode it to ISO 8859-1 and than save it as UTF-8. Sounds insane, but it was the only thing that works for me.

$doc->addField(Zend_Search_Lucene_Field::Text('lucene_DB_CLOUMN_NAME',utf8_decode($db_apater_result['DB_CLOUMN_NAME']),'UTF-8'));

WTF Zend Lucene!

compile lua on windows

Posted on by mario

Grab the “newest” (2008) http://www.lua.org/ftp/lua-5.1.4.tar.gz
unpack it. Compiling with VC++ is very easy.

Open the x64 %comspec% /E:ON /V:ON /T:0E /K “C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin\SetEnv.cmd” /Release
or x86 command line
%comspec% /k “”C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat”” x86

browse to lua folder and run

etc\luavs
copy /y src\*.* .\

Done!
