If you have a getty running on both machines with the above setup you can effectively cause both machines to hang as they each respond to the other's login: prompts. When fbsd is configured to provide serial console logins it seems repeated password failures may not result in a 'backoff' of the time between login:'s This deadlock caused the machines to become unresponsive to network logins requiring a visit to the site. -kim __________________________________________________ Do You Yahoo!?
