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

What a rocky start to labor day weekend

Woke up by earthquake at 7:00 AM in morning and then couldn't get to sleep. I took a bath, made my tea and started checking emails and saw that after last night deployment three storage node out of 100s of nodes were running into Full GC. What was special about the 3 nodes was that each one was in a different Data centre but it was named same app02.  This got me curious I asked the node to be taken out of rotation and take a heap dump.  Yesterday night a new release has happened and I had upgraded spymemcached library version as new relic now natively supports instrumentation on it so it was a suspect. And the hunch was a bullseye, the heap dump clearly showed it taking 1.3G and full GCs were taking 6 sec but not claiming anything.



I have a quartz job in each jvm that takes a thread dump every 5 minutes and saves last 300 of them, checking few of them quickly showed a common thread among all 3 data centres. It seems there was a long running job that was trying to replicate pending…

Email slavery

It seems I have become an EmailSlave. The first half of the day is spent in just answering to emails. There are so many emails where I am copied but I need not be. There are many emails  where its a 1-2 page email and somewhere down someone says @KP please answer this.  So it seems daily my work schedule is:
Signin to newrelic and check anomalies for 15 min. Check emails related production exception report and yes there are a ton of these report daily. Need a better tool here as this model is not scalable. I need to reduce the incoming data at me to only see relevant data like what newrelic does. May be I need to create a webapp out of these emails.Check emails for next few minutes before team callsDo team callsThen again back to checking emails until a I have taken a best shot at answering everyone waiting for my reply.Attend team meetings on Tue/Thu
Being an architect and coder at heart I don't feel satisfied at end of the day if there is nothing tangible getting done at the end.…
