I've recently been examining the use of jails in FreeBSD, and I have some questions I hope someone can shed some light on with respect to running virtual servers in jails.
1. Upgrading. This probably a "It Depends" question, but if a host system is upgraded (within version numbers), will the new kernel and world on the host system cause potential problems with existing jails when they are restarted? Or do the jails need to be rebuilt before they are started? 2. Localhost. Jails seem to be implemented using IP address aliasing, so anything within the jail that wants to, or is configured to, bind to the localhost address, now gets bound to the jail's IP address. This means that what was once local, is now publically available. Will running a firewall on the host system work in such cases? 3. Sendmail. The usual approach of setting "sendmail_enable=NO" (or using DAEMON_OPTIONS) won't prevent sendmail running in a jail from starting up and listening for incoming mail from external hosts. Short of disabling sendmail entirely, I'm wondering what approach most people use as a workaround. Thanks. Please copy me, as I'm not currently subscribed. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
