Clarification needed on Handbook: Tracking for Multiple Machines
Hi all. I recently acquired a laptop whose world and kernel I'd like to have built by a different machine on my LAN. Chapter 21.5 of the current Handbook lays things out pretty well, but I do have a couple of questions before proceeding. The Handbook states: Finally[,] make sure that /etc/make.conf on all the machines in the build set agrees with the build machine. That means that the build machine must build all the parts of the base system that any machine in the build set is going to install. Also, each build machine should have its kernel name set with KERNCONF in /etc/make.conf, and the build machine should list them all in KERNCONF, listing its own kernel first. The build machine must have the kernel configuration files for each machine in /usr/src/sys/arch/conf if it is going to build their kernels. So, two machines use the same world, except that a laptop doesn't want profiled libraries or games. Since the install is separate from the build, the build machine's make.conf must _not_ define NOPROFILE nor NOGAMES, but the laptop's make.conf _must_ define NOPROFILE and NOGAMES, such that both are present when `make installworld` is run on the machine that wants them, but they won't be installed when `make installworld` is run on the laptop, right? Second, two machines are of the same architecture, but they have different CPUs: One is an Intel PIII, but the other is a PII. Will the world built on a PIII be correct for a PII? Similarly, will the kernel for the PII built on a PIII be correct for the PII, given the different variables and settings in the two kernel configuration files? Finally, after briefly following the makefile chain, it looks as though what is written for -CURRENT is backward-compatible to 4.5-RELEASE? /etc/defaults/make.conf doesn't mention KERNCONF; /usr/src/Makefile.inc1 does. Since /usr/share/mk/sys.mk sucks in /etc/make.conf, that should propogate KERNCONF to /usr/src/Makefile, right? Thanks, Dave -- __ __ \__ \D. J.

Just make sure you build for 686. If that doesn't work, make it 586 (I think the PI qualifies as 686 but I'm not entirely sure). I think the extensions such as SSE etc are detected dynamically and shouldn't cause any problem. In all my years of messing with builds, I never run into this problem, so I guess it's pretty safe. Yes, both [my] machines define I686_CPU. Dynamically, as in at runtime? I think you're right, but I don't know for certain, either. This is exactly what I'm wondering about; the PII has only MMX, for instance, while the PIII has SSE and MMX2. I assume the world's codebase is CPU-agnostic within an architecture, but I really don't want to assume this; I'd rather know this. DJHJ Finally, after briefly following the makefile chain, it looks as though DJHJ what is written for -CURRENT is backward-compatible to 4.5-RELEASE? I don't think it is. 4.5 is OLD. You might not even find 4.9 to be backwards compatible to 4.5, much less CURRENT. Yes, 4.5-REL is old, but I have too much vested in my 4.5-REL systems to jump anytime soon. I have been maintaining my 4.5-REL systems WRT post-4.5 security updates (right up to SA-04:02), and for what these machines are and what they do, 4.5-REL is perfectly suitable. DJHJ /etc/defaults/make.conf doesn't mention KERNCONF; /usr/src/Makefile.inc1 DJHJ does. Since /usr/share/mk/sys.mk sucks in /etc/make.conf, that should DJHJ propogate KERNCONF to /usr/src/Makefile, right? You can also just supply it on the command line when doing your make runs. Yes, but this means individual commands for each machine's kernel, as opposed to one command for all machines (think issue command and go to bed, or even an `at` command). Are you stating definitively that what I saw in the makefile chain isn't what is really there? Dave -- __ __ \__ \D. J.

Something I should know about 'make buildkernel ...', but I don't.
Hi All.
Something's been bugging me about 'make buildkernel ...' (or pro'lly more
precisely, the docs): How do I re-make the kernel without first cleaning
/usr/obj/...?
After applying patches, I bump $BRANCH in /sys/conf/newvers.sh, and would
like the running kernel to reflect the current patchlevel, but not at the
expense of a complete rebuild. Something this trivial shouldn't get me in
any trouble, kernel-wise, should it?
Browsing Makefile.inc1, I see these defines:
-DNOCLEANDIR run ${MAKE} clean, instead of ${MAKE} cleandir
-DNOCLEAN do not clean at all
What does 'cleandir' do that 'clean' doesn't? Remove directory trees?
Anyway, is it as simple as:
make buildkernel -DNOCLEAN KERNCONF=...
Like I said, I should already know this.
Dave

So long as you aren't changing the kernel configuration, then you can
probably use the 'old' build mechanism:
[SNIP]
However, this is only worth doing if you're going to be recompiling
the kernel a number of times, as the first time through it will
compile everything.
Right! Most SAs these days don't effect the kernel. I usually leave
/usr/obj populated from the last build.
Note that this won't put the object files
etc. under /usr/obj...
Yeah, that's why I didn't want to do the old thang. I don't know
that it'd even work right.
But you seem to agree that something this trivial shouldn't yield a
broken kernel if /usr/obj/usr/src/sys/... is unchanged from the previous
build, right?

Stupid shell tricks
Hello all.
I'll cut right to it: I'm looking for a technique to do atomic writes
in a shell (sh(1)) script, playing with the trap builtin. It goes something
like this:
1: #!/bin/sh
2:
3: trapper ()
4: {
5:rm -f $TMPFILE
6:exit
7: }
8:
9: trap trapper HUP PIPE INT QUIT SEGV
10:
11: ...
12:
13: while read LINE; do
14: trap HUP PIPE INT QUIT SEGV
15: binary_that_writes $LINE
16: ...
17: done $TMPFILE
18:
19: trapper
Line 9 sets up the general-case signal handler to have the script clean
up after itself. Line 11 is stuff where I want the signal handler to do
it's thing. Line 14 sets up the atomic write by ignoring the signals.
So far, so good. Line 16 is my problem; this is where I want something
so the script exits _without_ cleaning up when the signal that would
have been seen/caught at line 15 occurs.
The trap at line 14 is inside the loop 'cuz I figure line 16 will be
another trap statement, but I seem to be wrong about this. So far, if
the trap at line 14 is anything else, line 15 gets interrupted. Using
nohup(1) at line 15 (without the trap at line 14) doesn't trap enough
signals.
I've tried quite a few different signal things, but none have produced
what I'm after. Anyone been here and done that? Oh, yeah, it has to be
a portable solution, too.
Thanks,
Dave

Re: sed(1) regular expression gurus - SOLUTION
First off, thanks to all of you who scratched their heads over this
puzzle. All had the right idea to some extent or another.
Based in part on the replies, and my own work, here's the final result:
FOLDER=$HOME/Mail/spam
NAME_RE=[[:alnum:]_.-]+
ADDY_RE=([0-9]{1,3}\.){3}[0-9]{1,3}
cat $FOLDER \
|grep -A 5 ^Received: \
|egrep ^(Received:| ) \
|sed -E \
-e s/(^Received:|by|from)[[:space:]]+//g \
-e s/\([HELO]{4}[[:space:]]+($NAME_RE)\)/\1/ \
-e s/\(($NAME_RE)[[:space:]]+\[($ADDY_RE)\]\)/\1 \2/g \
-e s/(\(\[?|\[)($ADDY_RE)(\]|\]?\))/\2/g \
-e s/[[:space:]]*(\(|id|via|with|E?SMTP|;).*// \
-e s/(\(envelope-|for|Sun|Mon|Tue|Wed|Thu|Fri|Sat).*// \
-e s/[][(){}]//g \
Note that the whitespace in the second pipe is one tab character.
The first two pipes isolate the multi-line headers. The first sed
command strips keywords and any following whitespace. The second
sed command returns the name in a parenthetical HELO or EHLO. The
third sed command returns the name and address in a (... [...]).
The fourth sed command - the one I inquired about - returns the
address in any of (...), ([...]), or [...]. The fifth sed
command strips possible whitespace, keywords or an opening
parenthesis (now that it's of no consequence), and anything after
them. The sixth sed command strips more keywords and anything
after them (it might be merged into the fifth, what it strips is
often on another line). Finally, the last sed command strips any
errant delimiters; strictly speaking, it's redundant, but when I
ran a spam file (~12.3Mb) through this, some delimiters did leak
through.
Just thought those that replied to my plea might like to see this,
and perhaps somebody else will find it useful. No, I'm not telling
what it's for. ;-,

Attn: sed(1) regular expression gurus
Hi all.
I'm getting really frustrated by a seemingly simple problem. I'm doing
this under FreeBSD 4.5.
Given these portions of an e-mail's multi-line Received header as tests:
by some.host.at.a.com (Postfix) with ESMTP id 3A4E07B03
by some.host.at.a.com (8.11.6) ESMTP;
by some.host.at.a.different.com (8.11.6p2/8.11.6) ESMTP;
by some.host.at.another.com ([123.4.56.789]) id 3A4E07B03
by some.host.at.yet.another.com (123.4.56.789) id 3A4E07B03
I want to isolate the addresses (one for the 1st through 3rd, two for
the 4th and 5th). Here's the sed(1) command I'm playing with:
echo by nospam.mc.mpls.visi.com (Postfix) with ESMTP id 3A4E07B03 \
|sed -E \
-e s/by[[:space:]]+// \
-e s/(\((\[?([0-9]{1,3}\.){3}[0-9]{1,3}\]?){0}\)|id|with|E?SMTP).*//
In all cases, the parenthetical word is returned, when only the last
two should return the parenthetical word. The idea behind the first
branch of the second sed(1) command is to match anything that isn't a
digits.digits.digits.digits pattern. I've tried simpler expressions
like \(\[?[^0-9.]+\]?\), but it fails on the third example.
What the devil am I doing wrong?? Am I exercizing known bugs in GNU's
sed(1)? Can anyone dream up a different solution - please, no Perl, but
awk(1) is fine.
Thanks,
Dave

There may be 'neater' ways of doing it, but it's the most concise
example I could come up with.
This is better than anything I've dreamed up with sed or awk, and is
really close, but it fails on this:
by nospam.mc.mpls.visi.com (8.11.6/8.11.6.2) with ESMTP id 3A4E07B03
The parenthetical is a [hacked] sendmail version. I don't see how the
script fails, though, as you do test for a full/complete dotted quad,
and even test for a BOL and EOL on either side it. The 8.11.6 shouldn't
match. I changed the '+'es to {1,3}s for even better precision in the
if (...), but it didn't make any difference (nor should it have).
BTW, why the one or more flag in the FS assignment?
You need to include the --posix option to get the '{3}' notation to work
(peculiar to GNU awk).
Kinda throws portability out the window, but I'll settle for it.

-e s/[[:space:]]*(\(|id|via|with|E?SMTP|;).*//
The idea being to pull anything that looks like an IP address out of
parentheses first (2nd command), then junk any other parenthetical
stuff with the other cruft on the line (3rd command).
I did learn a new syntax from your script, nonetheless. Thanks,

Updating FBSD on one slice from another slice
Hello all. I've got two similarly-sized, bootable, FBSD slices on a machine, one with 4.5 and the other with 4.2. My intention was/is to run the newer of the two, and upgrade the older by 'cvsup' and 'make [build|install][world|kernel]' _from_ the newer. So, I'm running the newer installation now, and I want to upgrade the older installation to 4.8. Doing the 'cvsup' seems straight-forward enough; just change the base and prefix defines in my supfile from /usr to /mnt/s2/usr (the mountpoint of the older /usr partition), bump the value of the tag define to RELENG_4_8, and run 'cvsup' as usual. Anything deleted or downloaded will occur in the mounted path of the other, older slice, right? What I'm stumped with is how to tell 'make [build|install][world|kernel]' to do their thing from the OS in the slice I'm running (the newer), but do the reads and writes on the other, older slice. Same conundrum with 'mergemaster'; how do I tell it to do it's thing on that older slice? A mountpoint on the newer slice I'm running, /mnt/s2, is the older slice's /, so the entire other, older slice is visible. Please CC me on replies to the list, as I'm not subscribed to it.

Re: About Patches
In article [EMAIL PROTECTED], [EMAIL PROTECTED] writes: Hi List, I need to apply some security patches to my FreeBSD(i386) 4.7-RELEASE box and I am concerned about the possibility that I could actually harm my system while trying to apply this patches. (I am not a Unix guru actually) Is there any particular reason you don't want to use cvsup(1) against the security or current branches? Release 4.7 is still supported by the Security Team, after all. See the Handbook if you don't know what this means. 1) Do I have to apply the security patches in a specific order? Sometimes, yes, sometimes, no. It will depend on whether any one source module has been updated (or not, more to the point) before. 2) Is there a chance were a patch requires a previous one? (In my case some patches are not applicable) Yup; see above, especially where the kernel is concerned. Even if a patch is for source a module that has never been patched before, it might depend on function asdf() in another source module being proper from it's (the patch's) own point-of-view. 3) What if the code is not in the state that the patch requires? (For instance if I have updated that port) Um, this is a tricky question. The answer could go either way. The nasty situation is when a source module isn't current enough for the patch to apply, but it should have the patch's functionality. 4) Are the patches clever enough to protect me from harming my system? Yes. If you use the patch(1) utility judiciously (correctly?), it can/will rename the existing file(s) being patched to *.bak. The script(1) utility is a Good Thing(tm) if you're patching things in an ad hoc manner; it'll let you go back further than the scroll-back of a console or xterm to see what was actually done. 5) Is there a safe way to undo a patch? Yup; see above. The patch(1) utility also understands reverse patches, though I've not used that functionality. Note: I'm not a developer or committer. I'm just another hack who has some experience doing this sort of thing. I have a web page for patching EOL'd kernels against more recent security alerts [and other stuff]. It has a section that you might find helpful: http://www.visi.com/~hawkeyd/freebsd-backports.html You should become familiar with reading a patch file before trying to patch things in an ad hoc fashion, both the contextual and unified diff formats.

SA-03:02 (OpenSSL) patches for RELENG_4_6_2: OK for RELENG_4_5?
Hi All. I posted this to hackers@, but it received no attention (rightfully so, I suppose). I should have tried here first. Are there any sharpies that can verify whether OpenSSL under RELENG_4_5 is the same as RELENG_4_6_2? I have a RELENG_4_5 box that needs the OpenSSL update, and it appears that only the FreeBSD CVS version numbers keep some half-dozen of the patches from applying cleanly. Checking out some files in the RELENG_4_6_2 CVS tree, it looks to me as though 4.6.2 was released with the same version of OpenSSL as 4.5 was. Am I correct? And therefore, the RELENG_4_6_2 patches are appropriate for RELENG_4_5? After applying said patches, does that make my RELENG_4_5 OpenSSL the same as RELENG_4_6_2? Thanks, Dave -- __ __ \__ \D. J.

send/receive email for her. She'll run it to check for mail and when
she's done composing her outgoing mail.
My initial untested idea is:
- ppp --dial HerISP,
- wait for the connection to come up
I can get you this far.
- kill the connection
This one, too. See the attached script.
Note that I had to hack some files in /etc/ppp to get things to work right
(auto-dialup when anything WAN-related happens). If you want these too,
I can supply them, but I have to wonder if the list is the right forum?
I used kernel-mode PPP, BTW.

jailed ftpd behind NAT'ing firewall: ftphosts?
Hi all. I want to set up a jailed FTP server on a box inside a private LAN, accessable to the outside. It all looks straight-forward enough, using a column on DaemonNews (http://ezine.daemonnews.org/200212/ftpjail.html) as a guildline, except that I want to use FreeBSD's ftpd(8). Reading the ftpd(8) man page, it seems I need to employ /etc/ftphosts, but try as I might, I can't find an example of /etc/ftphosts. The private network is 192.168.16.0/24. The public IP to my LAN is, say, 208.42.236.15. Do I need /etc/ftphosts to reflect the public IP, or does jail(8) handle this for me, or what? Even if I don't need /etc/ftphosts, could someone post an example? I find the man page sufficiently vague as to the actual contents, the user field in particular. It seems to me this is something I should just know. Thanks, Dave -- __ __ \__ \D. J.

XF86-4.2.0, libfreetype.so.8, and TrueType fonts
Hi all. Attached is a mail I sent to the author of XFree86 Font De-uglification (http://ldp.kernelnotes.de/HOWTO/mini/FDU/index.html), but have yet to receive a reply. A pertinent-to-this-group comment: I built Mozilla 1.1 from the ports, but the XFree86 package is from XFree86's own binary distribution for FreeBSD. I therefore hacked mozilla's port Makefile to use the XFree86- supplied libfreetype.so.8 instead of installing libfreetype.so.9; I don't want to clutter /usr/local with stuff that 1) seems un-necessary and 2) should be in /usr/X11R6 anyway ;-, Can anyone here help in lieu of the webpage author's absence?

Hope you don't mind this intrusion. First off, nice set of pages. I found them straight-forward, and up-to- date. Even the external hyperlinks aren't stale! However, I have run into an obstacle that's driving me nuts. Everything goes well until section 5.2, Xft and Mozilla. However, when I go into Moz's Edit - Preferences - Appearance - Fonts, and try to select TTF fonts, I don't get any that begin with an uppercase letter. They all are of a foundry-face-iso-digit style listing (like an abbreviated XFLD), and they are all lowercase. It doesn't matter what font I select, the same thing always occurs: Un-antialiased rendition until the fonts get _really_ big, and then only some fonts, at that. This is Mozilla 1.1, BTW. A few particulars: I'm running FreeBSD 4.5-REL-p23 and Xfree86 4.2, as supplied by the XFree86 project (that is, a binary package for FreeBSD built by by them). /usr/X11R6/include/freetype2/freetype/config/ftoption.h as supplied by the project has TT_CONFIG_OPTION_BYTECODE_INTERPRETER defined, and /usr/X11R6/lib has libfreetype.so.8 in it. I'm running a 1024x768, 75-dpi, display on a 15-inch CRT (I do hate how 100-dpi fonts look, TTF or otherwise). All the requisites of the X server are present (RENDER, etc.). I've run 'ttmkfdir' in the font directories, and used that Perl script (which needed a few small changes to run) to create font.alias files, just in case Moz needs that. I attach my /etc/X11/XftConfig and $HOME/.mozilla/default/.../user.js files; can you tell me where I've gone wrong? I can supply more info as you think you need, of course. Note that much of the TTF stuff in user.js is commented, but they make no difference when enabled either. Thanks, Dave -- __ __ \__ \D. J.

Looking for opinions: popd vs. popper vs. et.al.
Anyone fooled around with the various POP daemons in the ports? I'm looking for the one that: - is native to the BSDs - supports SSL, and plays well with fetchmail and MS clients - has the smallest footprint and consumes the least resources - is suitable for a small, private LAN, but may occasionally be hit from the outside - is straight-forward enough in configuration - doesn't have a lot of dependancies I'm leaning toward popd, but that's just based on the pkg-descr.

I'm just looking for something that does the job, looking nice would be an added benefit but I doubt I'll have a high color depth to play with anyway. You can't go wrong with Blackbox (or fluxbox, which is very similar). It can look as detailed or as simple as you want. I use it on my low spec laptop and workstations. If you want a nice looking theme, I suggest 'AlmostX', but you might want to get rid of some of the gradients in it, as rendering them chew unnecessary CPU power. It's been quite usable on my p120 thinkpad. With a fairly rich configuration, how small is fluxbox's footprint? I just had a peek at fluxbox's source, and I see that gradient shading is done with X pixmaps. If they're cached (by color and/or size?), this is rather memory hungry, no? I run vtwm with a rather rich setup on FreeBSD 4.5-REL-p22, XF86 4.2.0, TrueColor visual, and top shows the following: PID USERNAME PRI NICE SIZERES STATETIME WCPUCPU COMMAND 49880 hawkeyd2 0 3092K 2496K select 0:16 0.00% 0.00% vtwm It does cache pixmaps by size and color, but for the most part they're small - titlebar buttons.

How does that fair against fluxbox or blackbox? As X pixmaps are server-cached, how can one [easily] tell how much memory is used for them? As far as file managers go, I would suggest perhaps XFtree from XFce. I've not used every file manager, but I have used this in the past, its been good and has a small footprint. You can assign file associations too. I've used these both in the past, in a sort of hybrid blackbox-xfce manner, and it served me well.

OT: regex(3) and POSIX collating sequences
Hi.
This is rather off-topic, but as the trouble I'm having is on a FreeBSD
box, I'm hoping you'll excuse me.
What's up with collating sequences and the regcomp(3) function? From the
re_format(7) man page:
Within a bracket expression, a collating element (a character, a multi-
character sequence that collates as if it were a single character, or a
collating-sequence name for either) enclosed in `[.' and `.]' stands for
the sequence of characters of that collating element. The sequence is a
single element of the bracket expression's list. A bracket expression
containing a multi-character collating element can thus match more than
one character, e.g. if the collating sequence includes a `ch' collating
element, then the RE `[[.ch.]]*c' matches the first five characters of
`chchcc'.
But darned if I can get it to work:
$ echo ZXCV asdf qwer |sed -e s/[^[.ZXCV.][.1234.]]/zxcv/
sed: 1: s/[^[.ZXCV.][.1234.]]/zxcv/
: RE error: invalid collating element
Foolishness, yes, but it illustrates my problem nicely. I've got a program
that uses REs, and it reports this error when I try to use a [[.phrase.]]
bracket syntax. Relevant code example:
#include sys/types.h
#include regex.h
#define REGCOMP_FLAGS(REG_EXTENDED | REG_NOSUB)
regex_t re;
int result;
char *phrase = [^[.ZXCV.][.1234.]];
char buffer[256];
if ((result = regcomp(re, phrase, REGCOMP_FLAGS)) != 0)
{
regerror(result, re, buffer, sizeof(buffer));
regfree(re);
fprintf(stderr, regcomp(\%s\) error: %s\n, phrase, buffer);
}
This works for everything I've thrown at it except for a [[.whatever.]]
bracket expression. regcomp(3) refuses to compile it. The REG_NOSUB is
intentional; I only need to know that a match occurs with regexec(3).
What the devil have I missed? Or, what is an acceptable RE that matches
anything except ZXCV or 1234?
Please CC: me, I'm not subscribed. Thanks,
Dave
