heartbleed centOS6.5

Wondering if NSA already knew about heartbleed and was cracking google and FB and other servers so far.

now that its out people are rushing to fix it and we are also.

I saw a great into to heartbleed at http://vimeo.com/91425662

so if you run this it would tell you what version of openssl nginx is using
ldd `which nginx` | grep ssl
        libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007f6d0c0cf000) 

and now if you do this it would tell you if you are vulnerable 
strings /usr/lib64/libssl.so.10 | grep "^OpenSSL "
OpenSSL 1.0.1e-fips 11 Feb 2013

if you have anything between 1.0.1. and 1.0.1f you are vulnerable, perconna guys have a nice post on same http://www.mysqlperformanceblog.com/2014/04/08/openssl-heartbleed-cve-2014-0160/

CentOS has released patch to current stable release and to fix all you need to do is update centOS or recompile nginx and disable heartbleed.

to update centOS  run "sudo yum update openssl" and restart services using openssl like nginx,mysql,apache.

 to verify if its fixed run

Spring query timeout or transaction timeout

If you are using spring to manage transactions then you can specify default transaction timeout using

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
        <property name="defaultTimeout" value="30" /> <!--30 sec--->             
    </bean>

or you can override the timeout in the annotation

    @Transactional(readOnly = false, timeout=30)


or if you are doing it programatic transactions then you can do


DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource);
transactionManager.setDefaultTimeout(30);

 or you can override the timeout for one particular transaction

TransactionTemplate transactionTemplate = new TransactionTemplate();
transactionTemplate.setTimeout(30);

def writePidFile(): pid = str(os.getpid()) f = open('thumbnail_rabbit_consumer.pid', 'w') f.write(pid) f.close()
