More about cacert.org :

CAcert.org is a community-driven Certificate Authority that issues certificates to the public at large for free.

CAcert’s goal is to promote awareness and education on computer security through the use of encryption, specifically by providing cryptographic certificates. These certificates can be used to digitally sign and encrypt email, authenticate and authorize users connecting to websites and secure data transmission over the internet. Any application that supports the Secure Socket Layer Protocol (SSL or TLS) can make use of certificates signed by CAcert, as can any application that uses X.509 certificates, e.g. for encryption or code signing and document signatures.

I had issues with my mobile and reset it without taking back up of Google authenticator. Guess what, now I have no access to the worpress.com account to which my blog was linked. Tried everything and when nothing worked, had to create a new account in worespress.com…. Hopefully my subscribers will not have any issues with this change.

PID File for squid in Fedora – 21 ( Fedora.next)

So, the other day, I wanted to have squid store its pid in the regular ‘var/run’ directory. Good simple enough – just add the following to “/etc/squid/squid.conf” :

pid_filename /var/run/squid/squid.pid

and create the /var/run/squid directory. Simple, hold on not so fast. Reboot and psssst.. ‘/var/run/squid’ is gone. Finally found that /var/run is handled by systemd-tmpfiles and thus you need to do this as well:

cat <>/lib/tmpfiles.d/squid.conf
d /run/squid 700 squid squid
EOF

So, basically you need to tell tmpfiles to create the squid directory as well.. How complicated things are becoming 🙂
