TCP Connection – How to Determine Creation Time on Linux

Yup, use -r:

scp -rp sourcedirectory user@dest:/path

• -r means recursive
• -p preserves modification times, access times, and modes from the original file.

Note: This creates the sourcedirectory inside /path thus the files will be in /path/sourcedirectory

For tcpkill to work (i.e., craft a reset packet that has the correct sequence number and source port), there must be traffic. If nothing more is printed then there is no traffic. To verify you could run tcpdump -i eth1 port 443.
