Crypto Tunnels Wrapup Drawbacks TCP over TCP meltdown. Not problematic over short periods of time. Not problematic over decent networks. UDP over SSH/SSL not possible natively. SSH OpenSSH - pretty ubiquitous on Unix-like hosts. Requires you have shell access on/near the destination machine. SSL/TLS Common on much server software, especially mail protocols. May be supported in 'wrapper mode' or STARTTLS mode.
