Typos that needs to be corrected

Hi there,

I've decided to rename one of already existing topics not to flood with typos I've detected through the course.

Detected another typo in '3.5 Layer 3: Configuration', instead of '$ echo nameserver 4.2.2.1 » /etc/resolv.conf' we should have '$ echo nameserver 4.2.2.1 >> /etc/resolv.conf'

Please have a look,

Thank you a lot in advance!

Hi there,

Another typo detected in 'Lab 7.6' > 'Session 7 HTTP Servers' > '2. Create a new CSR.',

We have:
# /usr/bin/openssl req -utf8 -new -key \
                          -key /etc/pki/tls/private/ipvhost.example.com.key \
                          -out /etc/pki/tls/certs/ipvhost.example.com.csr

Should be:
# /usr/bin/openssl req -utf8 -new \
                          -key /etc/pki/tls/private/ipvhost.example.com.key \
                          -out /etc/pki/tls/certs/ipvhost.example.com.csr

Please have a look and correct.
