That is the shell prompting you for the rest of the command,
probably caused by you typing only one single quote, or a
single quote and a double quote.

I have a habit of enclosing sed/awk/grep search patterns in
quotes to avoid special shell characters. In this case it is
not actually needed. So you use:
	grep port=80 /proc/net/ip_conntrack

It is best to run this a few after trying to access a website.
