Re: svn and/or portsnap
Regarding my question, How do you get the ports tree or svn in that case if not using portsnap? Helmut Schneider had two suggestions: You install ports from CD/DVD. Or use pkg_add -r subversion. :) ftp://ftp.freebsd.org/pub/FreeBSD/ports/ports/ I guess I could use the latter and then build subversion among other ports, then subsequently switch to svn. This would also work, I would guess, if ports tree is installed by bsdinstall or sysinstall. Question arises whether the ports tree as downloaded in tarball by ftp would be compatible/in sync with portsnap or svn. If in any doubt, either delete /usr/ports/* or move to /usr/ports-by-ftp and then restart fresh with svn. I noticed the FreeBSD Handbook ports section was not up-to-date on the use of subversion with the ports tree. Maybe with subversion now being elevated in importance for updating system source code and ports tree, it could become part of the base system.

NFSv4 mounts succeed on 8.2, but fail on 8.3
hi, i'm trying to mount some NFSv4 shares served by a Solaris 10 server on our FreeBSD boxes. On FreeBSD 8.2, the mounts succeeded after explicitly specifying the resvport mount option (the Solaris NFSd refuses requests from unprivileged ports). On 8.3, mount requests are denied no matter what option i specify. The server always complains about the client issuing requests from an unprivileged port. is mount_nfs no longer honoring the resvport option in 8.3? anything else i might be missing? tia, tom. -- Thomas Duke Hager d...@sigsegv.at GPG: 2048R/791C5EB1http://www.sigsegv.at/gpg/duke.gpg = Never Underestimate the Power of Stupid People in Large Groups. ___ 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

I think I tried something like your second example last night.
I think I did
% cksum foodir/*
and had to compare each file from another file I was copying from.
it was tiresome to check each of dozens of files tho. I was here
at
desk for something obscene -- over 12 hrs. getting my new
[slightly
used:)] computer back to normal.
if there isn't anything that can compare entire dirs, it looks
like
it's time to hack a small program. tx, polyt.
Unix was originally created to do text manipulation. No need for a new
program when you can do it from the command line.
cd dir1 ; cksum * | sort /tmp/dir1-cksum
cd dir2 ; cksum * | sort /tmp/dir2-cksum
diff /tmp/dir?-cksum
Don't forget to remove temporary files when you are done.
Other useful commands:
cut
paste
You can use awk to pull out and rearrange columns:
cksum * | awk '{ print $3, $1, $2; }' | sort
This gives you a little easier diff in case you do have changes.
Friendly tip: if you did comparisons by hand for 12 hours then you
may have missed something.
no, it was several other tasks that I had t o do very carefully
by hand. I was going to write an awk script. I figured there
were others ways.
my desktop is a flavor of linux that i don't know. it seems to
be
lacking in many common unix binaries; md5 is one that I spent
an hour checking. zero.
your first way works very well and will serve. many thanks.
now I can listen to:
/Lectures on the Critique of Pure Reason
which is now safely in my home directory in several mp3 files.
It's a real shame Unix doesn't have a really good tool for comparing
two directory trees. You can use 'diff -r' (even on binaries), but that
fails if you have devices, named pipes, or named sockets in the
filesystem. And diff or cksum don't tell you if symlinks are different.
Plus you may care about file ownership, and that's where the stat
command comes in handy.
right. these are things you only discover the hard way.
Not that I'm volunteering, mind you. I ended up instead writing a
Python script to do copies of filesystems off of old machines I'm
putting to pasture. It's amazing how badly old versions of dump and
tar behave.
REmember CP/M and MP/M? I started out with a dual 8085/80888 box
with MP/Mand wrote notes and letters that were stored on 8
twin floppies. circa mid-1980's I transferred a boatload of
floppies
onto my 386 with SVR2 with uucp and others C programs on the 8088
box.
it took forever and things keep faulting, but I got it done.
eventually.
oh yeah, I remember the Kaypro «portable» which was as big as a sampsonite,
and despite being built like a tank probably couldn't handle a wrangling by

Last night in the wee hours there was a power glitch and I lost the mail. Enclosed is the first//next Q/A. I'll send along another one or two later today. One that I was playing around with *failed* and I'm trying to figure out why. - How can I uise my FBSD floppy drive to copy files to it (in this case, at work), and retrieve the files on my FBSD systtem at home. So far I've only seen examples that used floppies with a filesystem on them. Is there a simplr, more direct way? You can treat the 'raw' floppy device as if it is a tape drive, and use typically UNIX tape tools to read/write, such as tar and cpio. For instance, to copy the current directory onto a floppy to take home at night: (put the floppy in the drive, and cd to the directory where the files are; then ) % tar -cvf /dev/rfd0 . To read it when you get home: (put the floppy in the drive at home; and extract the tarball wherever you want the files) % tar -xvf /dev/rfd0 The flags -c and -x indicate create and extract mode, the ``v'' specifies verbose mode, and the ``f'' tells tar that the following argument is the file or device that tar acts upon. Here, it is the floppy devide. With cpio: (chdir to the directory where the files are) % ls | cpio -oc /dev/rfd0 To read a cpio archive from a tape drive: % cpio -icd /dev/rfd0 The flags -i and -o indicate copy-in or extract mode and copy-out or create archive mode. The ``c'' tells cpio to use the old, portablr ASCII archive format. And the ``d'' flag tells cpio to create directories where necessary. Do a % man cpio for much greater detail on this utility. - There are another one or two of the simpler Q/A's and one or two more involved. Then, for this month only, I want to write a paragraph or two about who I am and where I'm coming from.

Ideally, this information will end up on the installed host in a directory within /var. sysinstall docs don't seem to explain any sort of facility to accomplish this.

FreeBSD's md5 and GNU's md5sum don't behave the same. Specifically when reading from stdin (as in a pipeline) md5 sensibly just outputs the hash and a newline, whereas md5sum follows the hash with a - to indicate stdin as the filename. o ah shit. well, I spent at least ten years porting stuff--everything F'ing thing...So I'll have to find the md5 src and port it. then follow karl's example. and others'.

How do I set number of retries in Firefox?
[ no response on mozilla@ list, trying questions@ ] I have a problem with various parts of web pages stopping before getting completely downloaded.

where, Sir, is the header?!
which header?
this example I just copied /usr/src/usr.bin/find/ (entire directory
contents) to my home directory then added.
#include md5.h to the top of function.c (with the other includes, order
/may/ matter.. i did after the sys/ includes but before the others)
md5.h is in /usr/include, it's basically a wrapper around
/usr/include/sys/md5.h
then changed the function int f_print, added two lines
char * md5sum[32];
(void)printf(%s ,MD5File(entry-fts_accpath,md5sum));
then changed the two lines in Makefile, PROGNAME so i don't end up with
'find' executable and the other is -lmd so i get the library with md5
routines.
I think maybe I wasn't clear that i was editing function.c, and that there
is more to function.c than my example code.
I can put the source on git if you want, but it's pretty basic. Also i'd
have to research the second parameter in MD5File function, i don't actually
think that's what i thought it was. it is returning the correct hash, and
printing it out, as returned from the function.

o
where, Sir, is the header?!
which header?
this example I just copied /usr/src/usr.bin/find/ (entire directory
contents) to my home directory then added.
#include md5.h to the top of function.c (with the other includes, order
/may/ matter.. i did after the sys/ includes but before the others)
md5.h is in /usr/include, it's basically a wrapper around
/usr/include/sys/md5.h
sounds reasonable. if you have this compiler on fedsora, I'd like
to
see it for myself. I think I have gcc* installed.
so, whenever you have time... .
I'm not sure it's a good use of time (?) considering, as someone mentioned
previously, mtree is already working. In the case of doing the find/md5
tinkering project on Fedora or other GNU/Linux distributions, it would
likely IMHO be best to use non-BSD, ie Liinux 'find' and 'md5' sources.
I do think mtree (already mentioned) is the best way to go You dump the
checksum, etc into a file and use the file to verify the other path.
example:
$ mtree -K sha256digest,uname,gname -c -p . structure.mtree
$ cat structure.mtree
