Anyway, what vi editor sessions? I rarely use vi. You've somehow deleted /usr/sbin/sendmail. That's a bad idea. It's the way programs generally deliver mail on Unix (some use /usr/lib/sendmail, but that's obviously wrong *grin*). If sendmail were present, you'd not get the error message, and the message would look just fine. nvi, the vi that FreeBSD comes with in the base, allows for editor sessions to be recovered (basically just reminds people they were editing them on boot-up). It only shows that message if there were editor sessions to be recovered. Fix the sendmail thing, and you'll get an email about what to do. > 2) How on earth do I get rid of Sendmail?

An operating system isn't very operational without some form of MTA. Since FreeBSD has always come with sendmail, it'll probably stay using sendmail by default for some time. qmail, postfix, exim, and others are available in ports, and at least qmail and postfix know how to use mailwrapper to become the default MTA (make enable-qmail for qmail, and make replace for postfix, in the ports directory). mailwrapper is actually what /usr/sbin/sendmail is. man mailwrapper for more information. > 3) It seems that randomely when I make a new kernel, when it initializes > IPFW and says "(stuff), IPDIVERT DISABLED, default to deny, etc., etc.) but > the kernel config file clearly has "OPTIONS IPDIVERT".

(I'll post a partial config file if needed) Are you sure you're booting the kernel you've just built and installed? > 4) Where can I get information in FreeBSD's weird hard drive device naming > configuration? In the first place you look to find FreeBSD information, the FreeBSD handbook. Check http://www.FreeBSD.org/handbook/disks-naming.html, or /usr/share/doc/handbook/disks-naming.html on your FreeBSD machine. > 5) Speaking of that, some docs said that IDE devices are always named > wd(xxxxx), but my / is "ad0". Is root an exception? Why? Which docs are these?

I've never tried to get pgcc to work on FreeBSD, but my advice is to skip high optimisation if you value stability. And if you value support - not many people (if any) will check out problems for you if you use optimisations and refuse to attempt to reproduce those problems without optimisation. I've seen the problems, and they're not worth it. (and optimising the code of the ipfw program won't do much, nor I imagine would it do anything at all for the kernel code) Neil -- Neil Blakey-Milner nbm@mithrandr.moria.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
