ssl dump

The ssldump utility has a very similar syntax to tcpdump so in your case it would be something like this.

ssldump -ni 0.0 -v host 10.10.10.9 and host 192.168.1.10

Also the same as tcpdump, with the -w parameter for write. And you can read the same file with -r. So:

ssldump -ni 0.0 -v host 10.10.10.9 and host 192.168.1.10 -w /var/tmp/

I assume you want to peek inside the application data? If that's the case you will need to include the private key at the very least. A great article on ssldump can be found here https://devcentral.f5.com/articles/troubleshooting-tls-problems-with-ssldump
