Why do you not update FreeBSD properly? If you want to use 7.3, install kernel _and_ world.

About FreeBSD kernel newbies
Hi all, I was wondering if anyone has considered the creation of a kernel newbies mail list for FreeBSD. I am aware of two places where someone can ask questions about that: either freebsd-hackers@ or the "FreeBSD Development" forum at http://forums.freebsd.org. I've been following the Linux kernel newbies list for a while and I think it is very informative. Would it be good to have such a list?

zfs on 7.3 with 7.2 world
Hello, I want to start using ZFS v13 and I have FreeBSD 7.2 world with 7.3 kernel. Do I have to upgrade zfs/zpool binaries (and maybe some libraries) to 7.3 or only recent kernel version is required to work with ZVS v13 safely? And if I need to upgrade something in the world - what should it be?

Hardly new. It hasn't been the Next Big Thing since the '80s. Java was
the Next Big Thing in the '90s. We don't exactly have a new Next Big
Thing for the '00s, from what I can see -- and maybe that's a good thing.
Agile development is the Next Big Thing for development methodologies,
but that's a somewhat separate issue.

That's correct -- 2nd Ed is the ANSI C version of basically the same

IPFW at startup.
Hi all,
I seem to have one server that does not flush the /etc/rc.firewall rules
when the script taken from "firewall_type" starts up. That is to say when I
boot the machine, 3 rules seem to be still in the list when I do an ipfw -a
list. Those three rules appear to be from the /etc.rc.firewall script. The
rules from my /etc/ipfw.rules file DO get loaded.
Here are the three rules (100, 200, and 300), from /etc/rc.firewall.
setup_loopback () {
# Only in rare cases do you want to change these rules
#
${fwcmd} add 100 pass all from any to any via lo0
${fwcmd} add 200 deny all from any to 127.0.0.0/8
${fwcmd} add 300 deny ip from 127.0.0.0/8 to any
Here is my /etc/rc,conf setup:
firewall_enable="YES"
firewall_logging="YES"
firewall_type="/etc/ipfw.rules"
Here is my /etc/ipfw.rules:
enterprise# more /etc/ipfw.rules
# Loopback
add 1 allow ip from any to any via lo0
# Office and Home
add 00200 allow ip from xxx xxx xxx xxx xxx to any
add 00201 allow ip from any to xxx xxx xxx xxx
add 00202 allow all from xxx xxx xxx xxx to any
add 00203 allow all from any to xxx xxx xxx xxx
# Allow fxp0 out
add 00204 allow all from any to any out
# Allow local net
add 02000 allow ip from any to any via fxp1
# email
add 04000 allow all from xxx xxx xxx xxx to any
add 04010 allow all from any to xxx xxx xxx xxx
add 04020 allow all from xxx xxx xxx xxx to any
add 04030 allow all from any to xxx xxx xxx xxx
add 04040 allow tcp from any to any 25,587
add 04050 allow tcp from any 25,587 to any
# Bruteblock
add 08000 deny ip from table(1) to me
add 08001 deny ip from me to table(1)
add 09050 allow udp from any to any 53 in
# Email Test
add 09100 allow icmp from any to any icmptypes
0,3,4,5,8,9,10,11,12,13,14,15,16,17,18
add 65535 deny ip from any to any
Oddly enough, I have several machies that are setup identicly and this is
the only one that has stikky rules from /etc/rc.firewall.
Any one have any idea what knob might have been turned that causes the
sticky startup rules?

Is ZFS ready for prime time?
List, I'm ready to build a backup server and have two questions... 1) Is ZFS as of 8.1 Release considered to be ready for mission critical? 2) If I put ZFS on top of geli, will this, in any way, (other than performance) impair ZFS's features?

I won't argue the point! but how about "IEEE"? I subscribed
to that for years and some people noted that spoken as a word,
"Ieee" was like the primal scream! Hm maybe the EEE
language?!

About 2000, 2001 was when I shucked my "muuz" game/mind-machine

Yeah, it's on amazon.com, but "my bible" {seriously!} is good

I'd vote for "E" since that might have more positive connotations that "D". :-) Skip "F" altogether. Just about the whole Murray Hill gang stopped by Cray (in Chippewa Falls), late 80's, and I remember asking Dennis what the deal was with "C++"; I remember him dodging the thing. Whoever-invented-C++ did a convoluted job, i s my opinion. It might be nice to add classes to C, but that's about it. TWo questions: didn't IBM create CPL? And doesn't BCPL Stand for "British Computer Programming Language"? (I did have both editions of the C book by Brian and DEnnis; then loaned the 2nd edition and never got ti back.) I think Dennis gives credit to BCPL Somewhere.

I have done some projects using BCPL... in a mainframe (S370) running MVS in the 70's... it was lightning fast. we had made a kind of TSO (time sharing option) that runs on top of VTAM, to bring "online compile and run" cobol programs to the desktop... while a batch work responds in 3 hours, a TSO (written in bcpl) responds in seconds... Thanks for remember the "good old days" ... it is still active!!! => http://www.cl.cam.ac.uk/~mr10/BCPL.html Sergio ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

The issue is not to remove CVS via rsync - just to remove it from the FTP collection where it doesn't belong. There is nothing which prevents mirror sites from providing access to the CVS repo via rsync, even if they get it via CVSup... If it's useful (IE, any of the primary mirrors requests it) we can probably rather easily set up rsync access via cvsup-master. That said, I think rsync access is likely not too interesting for most master mirrors as they likely provide access to the repo via CVSup already, so they have cvsup installed already. -- Simon L. B.

You have revealed yourself as a newbie :) In the beginning there was CPL, the "Combined Programming Language." It was large enough to be infeasible to implement using then-current technologies, so the "Bootstrap Combined Programming Language" (BCPL) was invented, with the intent that the first CPL compiler would be written in BCPL. CPL never amounted to much -- I don't know whether it was ever implemented at all -- but BCPL developed a following. Someone (at Bell Labs?) produced a derivative called B, from which a few researchers at Murray Hill derived C.
