title: CIPE Got Cooler
---
<p>
Looks like <a href='http://sites.inka.de/~bigred/devel/cipe.html'><acronym title='Crypto IP Encapsulation'>CIPE</acronym></a> has improved a <em>lot</em> since last year. They've added a protocol-level ping (I used to leave a <code>ping -i 30 destination</code> running in a <a href='http://www.math.fu-berlin.de/~guckes/screen/'>screen</a> session so the <a href='http://www.netfilter.org/'>NetFilter</a> stateful stuff didn't forget about the connection), public key encryption (uses it to resolve a dynamic shared secret, also handles dynamic <acronym title='Internet Protocol'>IP</acronym> addresses in a more graceful manner), and probably more stuff that I missed. I'm trying to think of an excuse to use it again; too bad I already run almost everything over <a href='http://www.openssh.org/'><acronym title-'Secure Shell'>SSH</acronym></a> tunnels already. :(
