I note also that > it's a snapshot; maybe there was something wrong in that snap. This box has a hard drive from another box. In the previous box this system rang fine for ages. I did have to recompile a kernel to get it to work on this box. The kernel had support only for i486, now so I had to change that to work on this 586. I wanted to avoid a cvsup and a makeworld, but that's looking more and more likely. I sort of want to get this box up ASAP. It's my webserver, mail server, ftp server, etc. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
