Slightly OT - steaming data server software?
Slightly OT but since I'm going to run this on FreeBSD 7 I figured I'd ask here .. I have an application where data arrives in what is effectively continuous stream (actually NMEA messages from an AIS receiver) and I'd like to have a server where an arbitrary number of clients can connect to a tcp port and receive a copy of the stream.I could probably write this in perl without too much work but somebody has to have done something similar already - does anybody know of code that does this? (and yes I know sending the messages as individual udp packets would be easier - I'm already doing that internally but it doesn't work for opening up the data stream to the public). John. P.S. for those who are interested AIS data contains info about large ships at sea - you can see live SF bay data on a map here http://hd-sf.com/livemap.html ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

As is typical in such debates few of the participants cited any real evidence backing up their views and almost no attention was paid to the jurisdictional issues created by international lists. There was speculation that the request for deletion was prompted by the posters political views as referenced in his email signature which points to an article about middle east politics http://www.home.no/barbershop/smart/sharon.pdf With the debate he started Mr Krantz seems to have had ensured that his name will live in archives for the foreseeable future, referenced in articles such as this one which he has no copyright to and no control over.

using either of the following methods:
1. A slash (/) followed by the number of significant bits.
For example, an address with 33 significant bits
could be
specified as:
MAC 10:20:30:40:50:60/33 any
2. An ampersand () followed by a bitmask specified as six
groups of hex digits separated by colons. For example,
an address in which the last 16 bits are significant
could be specified as:
MAC 10:20:30:40:50:6000:00:00:00:ff:ff any
Note that the ampersand character has a special meaning
in many shells and should generally be escaped.
Note that the order of MAC addresses (destination first, source
second) is the same as on the wire, but the opposite of the one
used for IP addresses.
So
ipfw add 999 deny MAC any 10:20:30:40:50:60/33
would be a valid rule.

Am I correct in believing that all I have to do to make this happen is uncomment the line that says: #*.*@loghost and change @loghost to match my syslog server? That is, along with making sure that name resolution works correctly, of course. On the sending end that's it. On the receiving host you need to make sure syslogd has the correct setting to receive the log packets. There are security upsides and downside to doing what you propose. Upside: logs are on a different box - hopefully a secure one - so you have a record of attacks against the other boxes. Downside: log packets are unencrypted UDP so a black hat may be able to sniff them and learn about system configuration. In the end I think the upside wins.

How do I kill the console? (or how to make nullconsole work)
I'm running 5.4 BETA1 on a soekris 4801 board. The unit emulates a console on a serial port. I want to use the serial port for my GPS so I want the console messages from BSD to go away - an in particular I want BSD to ignore inbound data during the boot process. So far: I've used the regular mbr so that I don't get the disk prompt I've added boot to loader.rc before the beastie call so that it doesn't display the menu Both these change work However if I add boot.config with -n -m the system doesn't boot (and I can't tell why because I have no messages!) If I set console=nullconsole the system doesn't boot and again I can't see why. Does anybody have any wisdom on how to get nullconsole to work?

But what you've missed is that the overhead to manage the better utilization of the dual-pipelines created by HT costs more than it gains.

Hmm on my boxes the combined sys and intr cpu rarely goes over 20% - most of the load is user space. I'd venture that most people running user space appllications will see similar numbers.

USB disk hang - 5.4PRE - gstripe
I just upgraded a box to 5.4PRE and started experiencing regular system hangs at exactly 1AM - I traced it to BackupPC which was starting it's run at that time backing up to a gstripe set made from two 300GB USB disks. The first thing I assumed was that something in Samba or perl didn't like the 5.4 upgrade so I rebuilt my entire ports tree (portupgrade -fa) to be sure I had no old libs. It still fails. Next I moved the two drives out of their USB housings and put them on the IDE controller (disconnecting the CD burner to make space). It's working fine like that (all be it with disks hanging out the side of the machine). So it looks like USB is the culprit. A few data points: 1) It worked fine on 5.3 2) Motherboard is an Intel D845GVSR with a Celeron D 2.9Ghz and 512Mb Ram 3) USB disk interfaces are from a couple of WD external drives (although the drives are in fact Maxtor because I upgraded them WD boxes) 4) A single WD250GB disk also on USB seems to work fine it's only the stripe set that has a problem 5) When it fails the entire disk system locks (including IDE) but the machines keeps running until each process locks as it needs to talk to the disk 6) No meaningful syslog log entries Any ideas? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

If you made the stripe using something like gstripe label -v -s somenumber data /dev/mumble1 /dev/mumble2 then it will be persistent subject to gstripe being loaded in the kernel - use gstripe load or build a kernel with options GEOM_STRIPE You see something like GEOM_STRIPE: Device data2 created (id=889964967).

In the boot messages (device names will vary - I'm using two 300GB USB drives) - There is a .snap directory on the volume. Is this used by gstripe? Nope that's a ufs2 thing - I used newfs -O 2 to create a UFS2 file system on the volume. Is this treated like any other UFS2 volume that can utilize fsck, etc? Yes - although you might want to specify a block size as the defaults tend to assume lots of small files which is not always the case for very large stripe sets. - How resiliant is this volume if the system were to crash? The same as any other volume except that you have twice the chance of a hard drive failure which would be fatal to the volume. --Thanks!

I had an idea about using a tool similar to dd(1) take backup's of

My father has an old PII running Win98 (Don't ask don't tell... he's
using very old financial software ;). Needless to say the thing keeps
getting borked and reinstall of his entire setup is quite frustrating.
Now I was wondering if I could simply set the thing up with all the
programs that he needs + drivers + anti viral c but minus the financial
software ofcourse and the rip the disk out of the machine put in my
workstation make an image of it and keep it safe and when the machine
goes borked I could simply rip the disk out again put it in my machine
and dd the image back onto the disk and restoring the good-image setup
(then I would restore his financial stuff with the most recent backup
(wich he keeps on a zip disk).
Now my questions are:
1) When I dd the image back onto the disk:
What about the 'free' hd space ?
What about the bootloader for Win98 ?
The registry c ... ?
The bootloader, registry and all that are on the hard disk, so if you make an
image of the whole thing it'll all be preserved. The only thing I can think
of that you won't be backing up is your BIOS configuration, but that's
probably OK.
As for free space... if you've got an 80GB hard disk and you image the whole
disk, you'll get an 80GB image, no matter how much free space was on it. If
you want a more efficient way of doing things, I suppose you could put the
base system on a separate small slice, and just backup that slice...
but then you have to be careful to include the bootloader as well, which might
not be stored inside any slice.
If you zero the disk before you do the initial install of Win 98 (dd
if=/dev/zero of=/dev/(disk to zero) then all the freespace will be zero
blocks which will compress really well.
2) How do I make an image of the entire disk using dd(1) ?
Or should I use some other software ?
dd if=/dev/{disk to backup} of=/path/to/new/image/file
where {disk to backup} is something like /dev/ad0 (for full disk) or
/dev/ad0s1 for slice 1, and /path/to/new/image/file is where you want to put
the image.
Use the option bs={some big number} to dd to make it a faster (man dd for
more info).
Make sure you use the raw disk device (/dev/adX) not a partition (/dev/adXsY)
so that you get the bootloader.

Questions: 1) Has anybody done this? What should I watch our for? I haven't done this on FreeBSD or with USB drives (but have on Solaris with SCSI). Make sure all your USB drives always show up as the same device (in /dev) or you may wind up corrupting your system. geom labels take care of this - I already have three usb drives on this box and they change device names if I re-plug them and gstripe copes just fine.

Stable device names for USB disks?
I seem to recall there was a neat trick involving GEOM to allow USB disks to be mounted in the same place every time the system boots but I can't find it. Right now my system (5.3 RELEASE) seems to being a random da? device for each drive that changes with every reboot - clearly not a good situation. Does anybody have a fix for this?

Right now my system (5.3 RELEASE) seems to being a random da? device for each drive that changes with every reboot - clearly not a good situation. Does anybody have a fix for this? Two options: - Wire your devices down (man scsi) so that your usb controller is always, say, scbus1, and target 0 off scbus1 is da1. You may also have to wire down your boot controller and disk. - Use geom_label, label your FAT32 or ufs filesystems, and always mount /dev/msdosfs/blah or /dev/ufs/blah Very cool - I built a stripe set whihc is showing up fine a /dev/stripe/data2 but I can't get a single volume to show up I did tunefs -L data /dev/da1s1d - added GEOM_LABEL to the kernel config, rebuilt and rebooted but no /dev/ufs appears - what am I missing? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
