No, you have to a connection before you login. You want to *strongly*
consider using ssh instead of telnet. You may also be referring the
format of the DNS query result which known as
[2]http://en.wikipedia.org/wiki/Reverse_DNS_lookup
I DID have a connection. ??? Maybe I gave too much detail,
but the point is that the IP yielded by host/dig did not match
what "whatismyip.com" gave here. I'd like to know why.
After user/pass entry, it says connected from "user-yyyyyyy.cab"
(replaced seemingly random name with "yyyyyyy" in case
it's not transient)
My external IP here is 24.110.nnn.nnn
The issue:
When I use either "host" or "dig" to give me the IP address
from "user-yyyyyyy.cab", they tell me: 208.68.zzz.zzz
(Ping gives the same.)
So, I'm still at a loss, I think, to know the originating IP.
Should a firewall rule blocking 208.68.zzz.zzz actually
operate against 24.110.nnn.nnn?
I don't understand the question, what is the rule?
I'd STILL like to know the true source IP to be able to connect
back to it.
man sockstat
man netstat
Thanks. Did that:
"netstat -n" gives the correct IP.
"sockstat" does also.
I couldn't find anything in the host or dig man pages that
indicated to me that they could be made to yield the proper
24.110.*.* IP address.
About the "rule"::: I was just mentioning one of the reasons
I want the IP address is so I can monitor multiple bad login
attempts to block the troublesome IP with a firewall rule. I
ALSO would like the correct IP for another purpose (project),
that involves connecting back to the source IP.
I will give a try to find out which IP address the ipfw firewall
operates on - the 208.68.*.* one or the 24.110.*.* one. It's not
obvious which at this point to me.
Thanks.

tail -f *is* event driven. When a new line is appended to auth.log,
tail will output it.
You should probably use
$ tail -F -n 0 /var/log/auth.log

Content-Type: text/plain; charset=UTF-8
I am using IPFW on a FreeBSD-7.3 machine. Presently, I am loading
several tables for IPFW. So far, I have just keep the data for the
tables in the actual "ipfw-rules" referenced in the 'rc.conf' file
itself. What I would like to do is keep the data for these tables in
separate files and just have them imported when the firewall is loaded.
I have constructed a simple script that is called from the 'ipfw-rules'
file.
My question is if there is a better way of accomplishing this? Is there
a downside to doing this way? The data for these tables tends to be
dynamic and I would rather work with the separate files than edit the
master one and risk messing it up.

It shouldn't be to bad as I use that method to generate stats from log files
for snmp. The log files I tail have about 200 odd lines per second and the
boxes handle it fine. But they are decentish spec but not extravagant (dell

Definitely use the -F rather than -f option as it will handle log rotation

No, just track it with tail -f as was already suggested.
tail -f /var/log/authlog | while read aline; do; ... ; done
The code in the middle will get executed as each line appears in the
file. This even survives authlog renaming when you logroll.

A Google search for information from the above hasn't proven fruitful.
Any ideas how I could narrow down the exact problem and work out a
solution would be appreciated.

Hi egoitz
s/wich/which/g
What is this line?
mkdir -p /usr/local/freebsd7/boot/defaults
Should it be
mkdir -p /expert/netboot/freebsd8/boot/defaults/
?
I think the line "Let's copy device.hints for booting the kernel loaded
by loader in this pxe boot. Let's copy too
some routine files for loader (and for forth shell) and a loader
defaults config file." should be above the block of mkdir and cp
commands above.
The phrase "but really it's optional you may not specify -u" probably
should say "but really it's optional, you don't have to specify -u". As
written it means you are not allowed to :)
Could you have used ftpd in the base system instead of tftp in inedt.conf?

i used more strict search terms and found around 30 sites.
none seemed that promising.
what i am thinking of is functions that work in any of
several venues:
math,
[every] science,
strings,
filenames,
queues,
stacks,
arrays,
<whatever>.
thanks for your insights. i used something like
"c-language functions" :-)

Thank you very much for all your advices.
The device I'm going to 'talk to' is cesium clock with rs-232 interface.
So it is not possible to simply change the interface to differential
one. Connection cable can be short and the transmission speed can be
slow. The most important thing for me is to ensure the long term
communication. Not to lose any data is very important when periodically
monitoring cesium parameters. We are speaking here about months and
years of continous operation. That is why I'm afraid of something
'strange' happens to my rs-232 interface and communication. Maybe I'm
too afraid of strange magic, but still, is it possible that my rs-232
could change its transmission parameters as a result of e.g. nearby
elecrical interference ? Or, in general, what bad thing could happen to
me in such scenario.
Thanks a lot,
Greg

I still see VBox hanging the host system.
This time I was able to install Ubuntu-9.10, then I ran it and FreeBSD
hanged during Ubuntu system updates.
VBox worked fine before the late January. After this some kernel change
was checked in that caused immediate hangs. Later something changed and
now host OS hangs only after a while.
kernel module was rebuilt after the system update. nothing gets logged
in /var/log/messages.

For maths, I'm particularly fond of GiNaC (+CLN)
FreeBSD ports: math/GiNaC, math/cln
WWW: http://www.ginac.de/ and http://www.ginac.de/CLN/
Of course, there's also the more traditional stuff like math/atlas[-devel]
which takes forever to compile. ;-)

If you're interested in C++ classes for all this, you could check
out the STL (Standard Templates Library), and additional libraries
like Boost.

That's way too broad to yield useful results! :-)
I'd suggest that you browse the ports collection for stuff you like
(domain oriented), and in most cases, the ports will point to some
library or program written in C or C++ that you can learn from. Just
looking for C/C++ code per se is kind of pointless (IMHO), if you're
not motivated by a particular application.

I've had to connect medical vital-sign monitors to ruggedized mobile
computers over RS-232 and write the software for data collection. In
my case, communication was packet-based and each packet had a 2-byte
CRC16 field appended to the end, which made it rather easy to detect
corrupt data. The goal was to have reliable communication for a period
of a few weeks; the time between equipment inspections.
The only real problem I ran into was that certain power events, such
as attaching an external power supply to the computer or turning off
the display, would cause the serial port buffer to overflow and
corrupt one or two packets. This seems to be a peculiarity with the
computers that we're using, since there was no actual data overflow,
just corruption. I've tested everything using regular desktop machines
and never had this problem before. For our purposes, the loss of a
single packet is no big deal.
The point is that the reliability of the connection depends on the
equipment you are using. Use a shielded cable that's as short as
possible. A ferrite bead on the cable might help eliminate
high-frequency noise. Keep the cable away from power cables or
supplies. The lowest usable baud rate should be less prone to
corruption. Beyond that, there really isn't much you can do to prevent
errors at a physical level.
Obviously, be sure to configure your UART correctly (i.e. baud rate,
bits per byte, parity bits, stop bits, and so on). I've never seen a
UART reconfigure itself due to electrical interference, but it is
possible for you to start getting framing errors if the clock
synchronization is off. Here I don't really have any advice for you,
except to test everything as much as you can in its final
configuration.
Avoiding buffer overruns is the responsibility of the software that
you're using, but it can be affected by the OS. Consider the setup of
your system. If you expect a high load on the CPU, be sure to give
higher priority to the program that's reading data from the serial
port. If the program is kept in the run queue for too long, you may
start losing bytes (depending on how fast they are arriving and the
size of the receive buffer). If you're doing some processing of the
data as it arrives, consider running that code in a separate thread
from the one that's reading the serial port. How to design reliable
software depends on the protocol you're using.
Test everything... If it runs fine for a week, it'll probably be ok
for a month. However, I think that expecting the link to work for
several years without a single corrupt bit is asking too much (if that
is your goal). In general, when dealing with RS-232 the best you can
do is detect an error using parity bits or checksum/crc values at the
protocol level. Correcting errors after they happen could be
difficult.
When it comes to changing the interface type, you might consider using
a serial-to-usb adapter. I've used those successfully with an early
prototype of our system, but we later removed them to have a more
secure physical connection. This may or may not be good advice for
you. I'm just throwing it out there in case you start seeing corrupt
data with a regular RS-232 connection. Adding a high-quality USB
adapter (I used Tripp Lite Keyspan) means an additional buffer for
sending and receiving data. It also means more hardware that can fail,
which is why I say that it may not be a good option for you. Also, I
was doing this on Windows and have no idea whether FreeBSD supports
such setup.

Try searching for 'algorithms'.
One of my favorite sites for that is the Stony Brook Algorithms
Repositor: http://www.cs.sunysb.edu/~algorith/
The Algorithm Design book associated with that site is also quite good.
But most good algorithms sites and books will have something on the
topics you list.

I desperately need to make some progress on this issue.
Is it likely that the issue is real rather than hardware
or disk corruption? Earlier releases are operating OK on the same
machine.
I have now confirmed that:
debug.acpi.disabled=acad button cpu lid thermal timer video
still leaves the system crashing and powering down when idle for
a while. And the more extensive:
debug.acpi.disabled=acad bus children button cmbat cpu ec isa
lid pci pci_link sysresource thermal timer video
does the same.
I don't really need power management but with acpi disabled the
disks are not visible to the system.
Are there sysctl variables that can influence this behaviour?
Currently I believe we have:
hw.acpi.supported_sleep_state: S1 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S1
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: NONE
hw.acpi.sleep_delay: 1
hw.acpi.s4bios: 0
hw.acpi.verbose: 0
hw.acpi.disable_on_reboot: 0
hw.acpi.handle_reboot: 0
hw.acpi.reset_video: 0
hw.acpi.cpu.cx_lowest: C1
machdep.idle: amdc1e
machdep.idle_available: spin, amdc1e, hlt, acpi,
However on the earlier RELEASEs that work I note we do not have
machdep.idle or machdep.idle_available. Instead I find:
machdep.cpu_idle_hlt: 1
machdep.hlt_cpus: 0
Although I've not been able to relate this directly to my problem
from Googling it seems that there some issues with amdc1e under
BSD, Linux and perhaps Windows. But all the references seem to
amd c1e are related to systems in 64 bit mode while I am running
(or trying to run) i386 so I wonder why I have:
machdep.idle: amdc1e
Maybe my problem is not acpi as such but this idle mode.
My thought is to change this to
machdep.idle: hlt
or even
machdep.idle: acpi
Any comments or ideas please!
Thank you for your attention.

There are different options for each instance of Sendmail:
$ grep 'sendmail.*flags' /etc/defaults/rc.conf
sendmail_flags="-L sm-mta -bd -q30m" # Flags to sendmail (as a server)
sendmail_submit_flags="-L sm-mta -bd -q30m -ODaemonPortOptions=Addr=localhost"
sendmail_outbound_flags="-L sm-queue -q30m" # Flags to sendmail (outbound only)
sendmail_msp_queue_flags="-L sm-msp-queue -Ac -q30m"
$
So you have to set the sendmail_xxx_flags of the daemon you are using,
instead of the global sendmail_flags.

Nice post. This is exactly the sort of post that raises the signal to
noise ratio in web-based forums. Good job writing it :-)
You should probably try to grok some of the semantic markup requests
like .Op too though. For example this part:
: SYNOPSIS
: jail [-dhi] [-J jid_file] [-l -u username | -U username] [-c | -m]
: jail [-hi] [-n jailname] [-J jid_file] [-s securelevel]
: [-l -u username | -U username] [path hostname [ip[,..]]
Is commonly written in several lines. If you try to read each line
separately they do make sense, e.g.:
.Nm
.Op Fl dhi
Will render as:
jail [-dhl]
with the flag letters displayed in bold text.
The .Op macro wraps everything in [...] brackets.
The .Fl macro marks up 'command flags'.
It takes a bit of practice to write manpages using this sort of markup,
but the displayed output looks great in ascii, PostScript or HTML output
modes. So it's worth trying to learn more about it.

To: freebsd-...@freebsd.org
Message-ID: <20100412095...@aurora.oekb.co.at>
Content-Type: text/plain; charset="us-ascii"
Hi,
Recently during portupgrades fetchmail also got upgraded to
6.3.16. Since then I'm experiencing problems when trying to fetch
mails from a pop server via ssl.
Here's the error message I'm getting:
fetchmail: Issuer Organization: <anonymized>
fetchmail: Issuer CommonName: <anomymized>
fetchmail: Server CommonName: <anomymized>
fetchmail: <anonymized> key fingerprint: <anonymized>
fetchmail: <anonymized> fingerprints match.
fetchmail: Server certificate verification error: self signed certificate
34381474120:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed:s3_clnt.c:1056:
fetchmail: SSL connection failed.
The above message normally indicates that the cert on the server might
have changed. This however is definitely not the case (I'm managing
the server myself).
Asking google I found a similar report relating to fetchmail 6.3.16
(as in my case) under Linux:
http://bugs.archlinux.org/task/19043
So my questions are:
o) Has anybody else, using fetchmail with ssl, experienced the same
problems after a recent upgrade of fetchmail under FreeBSD?
o) Any known cure against it?
Last but not least, here's my config:
FreeBSD 7.3 recent as per April 09,2010. Fetchmail 6.3.16, openssl 1.0.0
Thanks much in advance for any clue,
-ewald

I sign here too - Lucas' Absolute FreeBSD covers practically all the aspects when you new to Unix. Its a good choice. A seperate computer for trying out and break'n'reinstall is also a good idea for a start.
Its like learning a foreign language. At the beginning you may wonder how anybody can ever understand this mumbo jumbo. Then you will get an idea of it and go into an experimental stage where many things go wrong. And after some years you wonder that there was a time before where you could not understand such an obvious, logical concept.
Good luck!

You have obfuscated all of the data so there is no way for anyone to
verify your conclusions. The message indicates that you are using a
self-signed certificate. That warning message is normal. Are you
attempting to verify the certificate with fetchmail? If so, remove the
check an retry the process.
You might be better served on the fetchmail forum.

Subject: cups 1.3.9 (from ports) && Cyrillic fonts
To: freebsd-...@freebsd.org

Content-Type: text/plain; charset="iso-8859-1"
Hello,
I want to print via CUPS (from the ports 1.3.9) in FreeBSD 8-CURRENT
UTF-8 text files with Cyrillic (and other) chars; see the very small
attached file; the conversion of the UTF-8 textfile is done by CUPS's
texttops and someone can simulate this without wasting paper with this
command:
$ CHARSET=utf-8 /usr/local/libexec/cups/filter/texttops 1 rleigh myfile 1 "" < testfile.utf8 > ps
and check the resulting PostScript file with a viewer, for example
Ghostview.
The mapping between the Unicode codepoints and fonts for CUPS is done in
/usr/local/share/cups/charsets/utf-8 which has for Cyrillic chars U-0400...U+04FF:
0400 04FF ltor single Courier Courier-Bold Courier-Italic Courier-Bold-Italic
Using the attached test file all is printed fine, all but the Cyrillic
line. If you run this through Ghostview it says (it seems for the
Cyrillic chars):
$ gs ps
GPL Ghostscript 8.63 (2008-08-01)
Copyright (C) 2008 Artifex Software, Inc. All rights reserved.
This software comes with NO WARRANTY: see the file PUBLIC for details.
Substituting .notdef for afii10035 in the font Courier
Substituting .notdef for afii10077 in the font Courier
Substituting .notdef for afii10085 in the font Courier
...
On a real printer all is printed fine, all but the the Cyrillic line.
Any idea what is missing? Is this a problem with CUPS or with the
viewer?
Thanks in advance

There have been several updates to php, php-extensions and php5-*
My php is now 5.3.2, most of my php5-* also 5.3.2, but
a portupgrade didn't want to upgrade php5-filter and php-imap (errors)
of php-extensions. They stayed version 5.2.12, 5.2.12 and 1.3 respectively.
I did
# pkg_delete -f php5-filter-5.2.12
# pkg_delete -f php5-imap-5.2.12
# pkg_delete -f php_extensions-1.3
and several pkgdb -F until it reported everything OK
Yet still, I can't compile php5-filter-5.3.2, nor php5-imap-5.3.2 or
php-extensions-1.4 (which
depends on these)
How to fix it?
This is what I get

Subject: detachable x session (X11 application that acts like
sysutils/screen)
To: freebsd-...@freebsd.org

Has anyone done anything with a program that acts like sysutils/screen
but with an X11 screen instead of a terminal? x2x and xnest both look
like they have some promise. Basically I work on projects located on
one of two systems, but I may bounce between another set of
workstations where I am physically located. If I am handling something
that I can work on console-only without trouble, I use
sysutils/screen, however some times I either need X, or X would be a
bit more effective for me. I'd like to be able to leave a xsession
running somewhere and be able to detach it and reattach to it between
login sessions.
Has anyone had experience doing this? What programs do you use?
Thanks,
-Jim Stapleton
