    tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)
Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:
remap prefix to Control + a


## DSL Examples
# simple match all query with term facet
ejs.Request()
    .indices("myindex")
    .types("mytype")
    .query(ejs.MatchAllQuery())
    .facet(
        ejs.TermsFacet('url')
            .field('url')
            .size(20))

                Add CA cert to local trust store on CentOS or Debian
              
          
Open a webpage that uses the CA with Firefox
Click the lock-icon in the addressbar -> show information -> show certificate
the certificate viewer will open
click details and choose the certificate of the certificate-chain, you want to import to CentOS
click "Export..." and save it as .crt file
Copy the .crt file to /etc/pki/ca-trust/source/anchors on your CentOS machine
run update-ca-trust extract
test it with wget https://thewebsite.org

Go-Language implementation of an SSH Reverse Tunnel, the equivalent of below SSH command:

   ssh -R 8080:127.0.0.1:8080 operatore@146.148.22.123

which opens a tunnel between the two endpoints and permit to exchange information on this direction:
