Perhaps you could install the system in a free hard drive, then add the other two and make them a mirror. Then you could keep your data in the mirrored pool and the operating system, as long as some data that you don't care to be mirrored, in the single drive.

watch(8) does not work in jails
Hi, I enabled `device snp' in my kernel config file and with this I can use the command watch(8) to see any tty device attached. For example : # watch ttyv0 Give me the output of the console. But in jails, it's not the same thing, I tried the following : # jexec 1 tcsh # su - People# watch pts/0 watch: fatal: cannot open snoop device Is there a limitation of watch(8), or jails ?

You'd be better off installing security/ca_root_nss otherwise you'll be stuck with a stale file. I don't know why you don't have it, it's a dependency of fetchmail and many other ports.

Looking at the fetchmail code, there is no value set for ctl-sslcertfile. I'm not sure what fetchmail's behaviour was prior to 8.1, so I do not know whether this has changed. I don't have a pre-8.1 install handy -- if the OP does, I'd be interested in knowing whether the string SSL trusted certificate file: appears in the output of env LC_ALL=C fetchmail -V -v --nodetach --nosyslog and if so, what filename appears after the colon.

I did discover the file it installed, /usr/local/share/certs/ca-root-nss.crt, and started to use it for fetchmail in place of the file from my old FreeBSD system. After I read the above note from RW I figured out it referred to a port, that I had the port, that it was a dependency of fetchmail and had been installed and was probably the source of the file /usr/local/share/certs/ca-root-nss.crt. Erik Norgaard also mentioned the port but I didn't understand at the time that he was referring to a port. He also mentioned the file /usr/src/crypto/openssl/FAQ which very briefly discusses the issue and mentions http://www.mail-archive.com/modssl-us...@modssl.org/msg16980.html which describes a mechanism for constructing a root certificate bundle from some obscure data file apparently produced by the Mozilla project, but of course I lacked the background to understand these things at the time. I still don't understand them very well. The relevant user options in my .fetchmailrc file are now: ssl sslproto SSL3 sslcertck sslcertfile /usr/local/share/certs/ca-root-nss.crt sslfingerprint ... Perhaps since fetchmail installs ca_root_nss as a dependency it should also default to using the installed ca root bundle file. Perhaps the fetchmail port should have produced an installation message that mentioned these things. Perhaps the port should patch the fetchmail man page to suggest using this file with the sslcertfile option. I have looked very very hard for documentation on this stuff in an obvious place but have not found any. Where should I have looked?

Subject: Open Mail Relay
I have a machine running FreeBSD, sendmail and majordomo. I have someone
who is on one of those majordomo lists complaining that they are receiving
spam from me. The complainer says I have an open mail relay that I need
to fix.
I went to http://www.abuse.net/relay.htmlhttp://www.abuse.net/relay.html
to test the machine using its IP address. Abuse.net gives a clean bill of
health, saying relaying was denied in 17 separate tests.
I've reviewed my mail logs for the past couple of days and I can't find
any entries for any mail addressed to the complainer's domain name except
mail that should have been sent.
Is Abuse.net's test adequate to rule out an open mail relay problem?
There are -several- possible sources of spam to that list user.
The abusenet open-relay tests check only one of them.
The machine ay be compromised (ie.e 'owned') andthe bad guys have
installed their -own- mail-sending software on it. the logs that
show activity from _your_ mail-sending software would, obviously,
*not* show the activity of this other software.
In additon, whatever mailinglist said user is subscribed to _may_ be set
to take messaes from 'anybody', not just confirmed members of the list.
Thirdly, some folks sign up for a list _just_ to send their off-topic
commercial messages to it.
NONE of those three scenarios are an 'open relay', but they all result
in spam showing up in the list-subscriber's mailbox, that got there by
_from_ your machine.
Thank you everyone for your many comments and suggestions. The level of
talent and responsiveness on this list is nothing less than stunning.
I've requested copies of the offensive messages, and I'm hopeful the
complainer will send me copies. I believe I have control over the majordomo
lists -- postings are restricted to list members, postings are monitored, and
many lists are moderated.
Assume, as Mr. Bonomi suggests, that some bad guy has installed some type of
additional mailer on the machine or another machine that's allowed to relay
mail. How would I go about locating that other mailer?
*IF* the machine has been comrpomised, then you're going to have a -very-
difficult time finding it, using any tools _on_ the box. It's not uncommon
for the bad guys to install 'modified' (to use a polite word for it)
versions of system utilities, and/or run-time-loading system libraries,
that selectively 'edit out' information that they don't want you to see.
e.g., a modified ps(1) will -not- show the 'bot' process that is spewing
mail.
A _second_ machine, on the same LAN, using something like 'tcpdump' to
monitor outboud port 25 traffic from the first box, can show you if there
are 'things happening' that are not being reported in the log files.
_Finding_ the offending code, after you've established that it *is* happening,
is a whole nuther can of worms. _if_ you have something like an up-to-date
'tripwire' database, with fingerprints of every installed executable, you
can boot from alternate media (say the 'live CD' image), and look for things
where the fingerprint has changed.
If you establish a compromise -has- occurred, about the only way to *ensure*
that the machine is 'trustworthy' again is to back up all application *data*,
wipe the drive(s) {as in 'dd if=/dev/zero of=/dev/ad??'}, and re-install
everything FROM SCRATCH.
NOTE: This _is_ a 'worst case' scenario. Odds are that when you see the
'full headers' on the 'offending' messages, it will turn out to be something
else entirely.
Comment: someone who _knows_ what they're talking about would not simply
make the bald assertation 'you have an open relay' -- they would *know*
that that statement _alone_ is insufficient to get to the root of the problem
and fix it. They would, at a minimum, identify the _type_ of traffic that
was being relayed (e.g. 'from is spoofed as your domain'), or would provide
several copies of the offending traffic, _before_ being asked. Based on
this, the 'quality' of the original complainant's is somewhat suspect itself,
Probably the most _common_ situation is a spammer signs up to a mailing list,
*NOT* to spam _through_ it, but to collect the email addresses of those who
post _to_ the mailing list. And they then send junk email to those people
directly. Now, if somebody is using a 'unique' email address for that
mailing list, they *can* jump to te onclusion that 'anything' to that address
must jave come from/through your servers. I haven't seen anybody doing this
kind of thing 'smart enough' so as to make it appear (in received headers)
that it originated from the mailing-list server; it's

We've been trying to raise awareness for years.. I do not know any scientific group using FreeBSD anymore. Most of those groups used FreeBSD changed to Linux (mostly Redhat, some Ubuntu). Watching Phoronix and their benchmarks speaks clear what OS is the first choice. Well, I like the staright forward, centralised organization and the academic heritage of the BSDs and I would miss ZFS. The essence is: there is no serious reason to convince compiler vendors or vendors of 3D graphics chips of supporting FreeBSD for a specific purpose if there is no need -statistically. AMD/ATi in conjunction with OpenCL/LLVM was a great hope since the GPU vendor offered 3D specs of their chips to opensource vendors. But on the other hand nVidia seems to be much better supported by Gallium3D these days although they haven't offered internal 3d specs. I'm confused and at the end I have to decide. At the moment the comunity of astronomers and astrophysicist is sharing several very interesting N-body simulation code based on CUDA (open source) but users and maybe rare scientists still using FreeBSD are excluded from using those benefits. ___ 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

Since modern 3D accerlerated and GPGPU capable drivers are developed dominantly under Linux, BSDs lack in modern architectures like KMS necessary running those modern drivers, so in case of the 64Bit video drivers it could be more a lack in the underlying technical infrastructure than the low number of users.

Since modern 3D accerlerated and GPGPU capable drivers are developed dominantly under Linux, BSDs lack in modern architectures like KMS necessary running those modern drivers, so in case of the 64Bit video drivers it could be more a lack in the underlying technical infrastructure than the low number of users. But I do not know. Oliver The amd64 driver was an illustration of something where raising awareness or whatever you might call it actually helped IMHO. Unfortunately this is a chicken-and-egg problem. No HPC users means no demand means no incentive to do something about it means no HPC users ad infinitum.

Upgrading ports while processes are running.
Hiya All, I just finished upgrading perl on one of my machines and something crossed my mind while it was busy compiling and reinstalling all of the ports that depended on perl. Will a port install fail if it cannot write to a file because it's in-use? Also, is it necessary to restart the server or at lease the apps after a port upgrade? The answer to the second question is certainly yes. But is it considered dangerous to upgrade a port that is currently running? Things like mysql and apache come to mind. To take it one step further, what about shared libraries? If a process is using a shared lib, then it seems that it does not lock the file for writing, but I would think that it would not start using the lib until you restarted all of the processes that used that shared lib. Once the last process using the shared lib is killed, is it automatically unlinked from memory? I guess best practice should be to restart the system after a major port upgrade (unless you know which processes depend on the files that have been upgraded - then you should just be able to restart those processes). -D ___ 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

At least, the step that wants to write will fail, and this will mostly be (finally) signaled by a make error. UNIX doesn't have a file in use paradigm per se; i. e. you can open one and the same file in two editors simultaneously, and depending on which editor performs SAVE FILE, the file's content on disk will vary. Of course, there's file locking (see man flock). Also, is it necessary to restart the server or at lease the apps after a port upgrade? This depends on the programs. In most cases, it's useful to stop a kind of server app before performing the update, and then restarting it after the upgrade has been performed. Restarting the server isn't neccessary in most cases. You usually won't have much trouble with programs that are started many times (like editor, media player), as they will surely survive an update, and don't affect the system if they won't. The answer to the second question is certainly yes. But is it considered dangerous to upgrade a port that is currently running? Things like mysql and apache come to mind. I always went with the method stop, upgrade, start - it's not that short downtimes (planned!) have gotten me into trouble. :-) To take it one step further, what about shared libraries? If a process is using a shared lib, then it seems that it does not lock the file for writing, but I would think that it would not start using the lib until you restarted all of the processes that used that shared lib. Once the last process using the shared lib is killed, is it automatically unlinked from memory? I think so, allthough I think there's a caching mechanism for shared libraries (ld cache). I guess best practice should be to restart the system after a major port upgrade (unless you know which processes depend on the files that have been upgraded - then you should just be able to restart those processes). Most server apps provide rc.d style scripts which makes it quite easy to cleanly stop them before the update, so you don't have to manually hunt processes. This mechanism enables you to selectively prevent programs from being interfered by their respective updating procedures. A system reboot is highly encouraged when updating the OS or kernel components. If you are unsure and don't care for uptime, you *can* reboot, as it won't make things worse. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ 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

This is sort of pedantic for me to bring up, but I wouldn't count on the
install failing. Because Unix makes a distinction between unlinking and
file deletion, you can generally unlink the binary of a running
executable without any problem; the filesystem won't actually delete it
at least until the process in question stops running and the inode's
reference count drops to zero. See Advanced Programming in the Unix
Environment for details.
Here's a quick example on FreeBSD:
$ cat hello.c
#include stdio.h
int main(int argc, char* argv[])
{
while (1) {
printf(Hello\n);
sleep(1);
}
return 0;
}
$ cc -o hello hello.c
$ ./hello
This simple program will start printing Hello repeatedly. Now if I
switch to another terminal, I can delete the hello binary:
$ rm hello
But switching back to the first terminal, I see the program is still
running just fine. Running programs can be unlinked.
And this is what the install program used by FreeBSD ports appears to
do; from /usr/src/usr.bin/xinstall/install.c:
create_newfile(const char *path, int target, struct stat *sbp)
{
char backup[MAXPATHLEN];
int saved_errno = 0;
int newfd;
if (target) {
/*
* Unlink now... avoid ETXTBSY errors later. Try to turn
* off the append/immutable bits -- if we fail, go ahead,
* it might work.
*/
if (sbp-st_flags NOCHANGEBITS)
(void)chflags(path, sbp-st_flags ~NOCHANGEBITS);
if (dobackup) {
if ((size_t)snprintf(backup, MAXPATHLEN, %s%s,
path, suffix) != strlen(path) + strlen(suffix))
errx(EX_OSERR, %s: backup filename too long,
path);
(void)snprintf(backup, MAXPATHLEN, %s%s,
path, suffix);
if (verbose)
(void)printf(install: %s - %s\n,
path, backup);
if (rename(path, backup) 0)
err(EX_OSERR, rename: %s to %s, path, backup);
} else
if (unlink(path) 0)
saved_errno = errno;
}
newfd = open(path, O_CREAT | O_RDWR | O_TRUNC, S_IRUSR | S_IWUSR);
if (newfd 0 saved_errno != 0)
errno = saved_errno;
return newfd;
}
That isn't to say you won't see any negative consequences from
overwriting a running port with a newer version. Hypothetically, you
might install a new Python including a new standard library, and if your
running (old) Python process tries to load one of its deleted modules
from disk something could break. Or not; I'm no expert on the ports
system, they might have some way of working around this. But as for a
pragmatic answer to your question, I err on the side of caution with
this stuff :)

FreeBSD Downloading problem
Hey, I'm trying to install FreeBSD on a Dell PC with Intel Pentium 4 processor. When I insert the CD, read error, 0x01 appears and nothing else happens, I've tried restarting and changing settings, but no luck. I'm going to try re-burning the CD any other way I can fix this error?
