Depending on what "numeric" means, this may be ok. For other numeric values (e.g. floating point numbers) There are simple, fast and correct ways to check but you have to escape from the shell, e.g.: $ var=3.1415926535897931 $ python -c "$var + 0.0" >/dev/null 2>&1 ; echo $? 0 $ var=3a.1415926535897931 $ python -c "$var + 0.0" >/dev/null 2>&1 ; echo $? 1 The overhead of spawning a full-blown language interpreter like Perl or Python may be acceptable if you have to check "a few" values. Then it may be overkill if you want to check a million values. It's really up to you, as a programmer, to pick the right method. ___ 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"

yea but none of them are for freebsd style .sh shell
I'm, using
[ "${dup_times}" != [0-9] ] && exerr "value not numeric"
and get the errot messahe no mater what value is in dup_times.
What is wrong with this code?
Tried this suggestion from a reply and it worked.
Only valid numeric value is whole numbers.
if expr "${dup_times}" : "[0-9]*$"
then
echo "value is numeric"
else
echo "value is not numeric"
fi
But when I tried this format
[ expr "${dup_times}" : "[0-9]*$" ] || echo "value is not numeric"
I get the error message no mater what the value is.
What am I doing wrong?

Problem running fdisk via sysinstall
I hope this question isn't too stupid. I have a machine with a 3Ware RAID card, with 4 SATA drives attached. 2 drives are 250GB in a RAID1 volume, and act as the boot disk with a standard freebsd partiction map (/, /var, /usr, and swap on this disk). The other 2 drives are 1TB in a RAID1 volume, intended to be mounted as a separate data partition. At boot both volumes are recognized: Jun 22 18:38:51 ebi7 kernel: da0 at twa0 bus 0 target 0 lun 0 Jun 22 18:38:51 ebi7 kernel: da0: Fixed Direct Access SCSI-5 device Jun 22 18:38:51 ebi7 kernel: da0: 100.000MB/s transfers Jun 22 18:38:51 ebi7 kernel: da0: 238408MB (488259584 512 byte sectors: 255H 63S/T 30392C) Jun 22 18:38:51 ebi7 kernel: da1 at twa0 bus 0 target 1 lun 0 Jun 22 18:38:51 ebi7 kernel: da1: Fixed Direct Access SCSI-5 device Jun 22 18:38:51 ebi7 kernel: da1: 100.000MB/s transfers Jun 22 18:38:51 ebi7 kernel: da1: 953664MB (1953103872 512 byte sectors: 255H 63S/T 121575C) da0 is fine, and the system boots off of it with no problem. When I try to add da1 to the system, I get the following: * Run systinstall, Configure, Fdisk, select da1 * Get the friendly warning about the large geometry, click "Yes" * Hit "A" to use entire disk. Hit "W" to save, click "Yes", select "None" for boot record. * Fdisk says: "Wrote FDISK partition information out successfully." * Per handbook, get out of sysinstall and re-run it, then try to Label. In the label editor, it knows nothing about da1 (the device can be selected when going into the label editor, but I can't create any partitions). At the time when Fdisk says "Wrote FDISK partition information out, successfully." this gets logged to /var/log/messages: Jun 23 17:11:18 ebi7 kernel: GEOM: da1: corrupt or invalid GPT detected. Jun 23 17:11:18 ebi7 kernel: GEOM: da1: GPT rejected -- may not be recoverable. I've tried several variations, including running the command-line equivalents, but keep hitting this same error (fdisk thinks everything is good, but the GPT error is logged). I've also noticed that /dev/da1 exists, but there is no /dev/da1s1 or /dev/da1s1e ... I'm not sure when those should get created. And the final possibly-relevant tidbit: these drives used to be part of a different RAID on a linux system. They've been re-initialized into the RAID card on this system, and I've zero'd the first 1k of the volume with dd, so I don't *think* that should be a factor. I've worked with about a dozen systems with the same hardware in the configuration outlined above and haven't seen this problem before. But I'm usually using fresh new disks so maybe it matters.

Network card attaching to the wrong driver
All, I am running 8.0-RELEASE and having trouble with the ed driver that is compiled by default into GENERIC. My machine is actually a VM running under Parallels Server Bare Metal 4. I would like my card to be attached to the Parallels driver in ports (pvmnet) instead of ed. Is there some boot option I could use? Both device drivers are looking for the same PCI vendor/device id in their probe routines, and both drivers return the same value from their probe functions (so they have equal priority).

You did not mention that you have configured it. After X has been installed you must go into the X configuration file and configure your keyboard and mouse etc for use with it. When I installed X on my version 7 BSD I had to use some time tuning this file so X would work properly. The file gives you alternatives like which language keyboard you use and how your mouse works and other settings.

In case /var is not mounted, the /var directory on / will be just a "plain directory". Depending on program behaviour, it is possible that logging programs create a new file when missing a file to append. In this case, / will fill with such files in /var. It's important to remove them prior to re-mounting /var. It is possible to move them, e. g. to /tmp, and immediately append them to the correct files after re-mounting /var. But if (small) data loss is acceptable for the time needed to fix /var, it is an option. Another possibility is - but I never tried it - to force fsck to check a mounted partition that is in use. # fsck -yf /var This may (!) cause other forms of damage, allthough fsck should be able to correct most usual problems. It's a good approach to stop as many services as possible that could want to write to /var, and restart them after /var is clean and mounted again. -- 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"

Bad. :-) No, seriously, I just don't trust it. I can stand downtine, so I better let fsck do its work on unmounted partitions than letting it run in the background, while the system boots up with possibly dirty partitions... and you never know what else can happen.

Also note that "legacy PC console" means syscons, so unless this is a
headless machine you only connect to via a serial port or ssh, you probably
want to leave it enabled.

For other reasons I'm limited to about 500k states...since our typical hardware build has at least 4GB of RAM, I'm not overly concerned about RAM exhaustion when routing. As I stated in another post the potential for something like a squid cache does exist, in which case I'll take all the RAM I can get my hands on (a 16GB+ build is not out of the question at that point). Preliminary testing has been favorable. My big concerns have mostly been related to state and packets per second. The first test environment was as follows: | one NIC, 4 routable addresses | | -- | FreeBSD 8 Router | -- | | one NIC with aliases for | 10.10.10.254 | 10.10.20.254 | 10.10.30.254 | 10.10.40.254 | |switch| Attached to the switch are four workstations/laptops: 10.10.10.1/255.255.255.0 10.10.20.1/255.255.255.0 10.10.30.1/255.255.255.0 10.10.40.1/255.255.255.0 All connections are gigabit. The idea is that in a production environment, we'll have multiple /22 networks coming in so I wanted to test having multiple network aliases. There will be a pool of public addresses for the outside interface(s), possibly as large as a class C but probably 20 - 30 addresses. By using sticky-address on a NAT rule, we can watch each RFC-1918 address get mapped to a different outside address via round-robin while enforcing that all connections from one inside host are consistently mapped to the same external address. Generating 10k active pings on each of the workstations/laptops, we were able to get an idea of how the machine would respond with 80k active states (two per connection, one in each direction). Adding in a couple of BitTorrent and HTTP .iso downloads only supported the conclusions we were beginning to form. Currently I'm testing it with multiple BitTorrent downloads and a very lively World of Warcraft installer. While nowhere near an indication of what we could expect in production it is showing us RAM usage, processor usage and state maintenance behaviour that gives us pretty good indications that we can go ahead and test in a larger environment. Like I said, we are otherwise limited to approximately 500k states (actually 250k connections) and only about half of that will be allotted for the population this project is targeting so testing with 100k states is actually pretty realistic at this point. We will wait, of course, to attempt a production deployment until after we have tested with a larger sample of the target population.

Dan, many thanks
I wish src.conf(5) man page were more descriptive on this option.
At present it only contains:
WITHOUT_LEGACY_CONSOLE
Set to not build programs that support a legacy PC console; e.g.
kbdcontrol(8) and vidcontrol(8).
so I though it doesn't affect moused.
Maybe I should post to @doc about this..
thank you again

Bruce - sorry for taking so long to reply, this project has been slow-moving. Yes, you are correct, OpenBSD is typically used in this situation and, if the project were strictly for a routing component, it may indeed be a better choice. My concern was that if we decided to add any proxy capability then we would need much more RAM than OpenBSD could address (this will front at least 8k users). I have found the OpenBSD installer to be quite friendly but that's probably because it is pretty minimal and just sort of "clicks" with me. As long as you're dedicating the system to *BSD, I generally prefer the OpenBSD installer for its flow but have found no particular allegiance with either their installer or sysinstall. As long as I can have a running system within four or five minutes of powering on with the install CD, I don't really care. kmw -- A: Maybe because some people are too annoyed by top-posting.

There are many archiving formats -- dump, tar, cpio, etc. etc. which fulfill the space usage criterion, but they aren't filesystem images in the sense that you could mount them on your system. Probably the closest thing is to create a .iso image using something like growisofs(1m) (from the sysutils/dvd+rw-tools port), but while you can mount a .iso as a file-backed metadevice you can't mount it read/write. There is the Union FS type -- see mount_unionfs(8) -- where the overlay layer just contains the changed files made since the filesystem was mounted. Which is sort-of what you're asking about, but not quite the same thing.

If you mean you would like to make a sparse file and attach it using mdconfg then dd if=/dev/zero of=/path/to/outfile bs=1M seek=1024 count=0 This will give you a sparse file that reports a gig in size, but only uses whats actually in use. you can then use mdconfig(8) to allow this to be partitioned formatted and mounted. Example below. see also http://www.freebsd.org/doc/en/books/handbook/disks-virtual.html although that example doesnt use a spare file.

Back to your FreeBSD adventures, heh ;) You can certainly use sysinstall to create the slice. I suggest you use the command line bsdlabel to create the partitions. On your current system, use dump/restore to dump /, /var and /usr to the new disk directly (or you can save the dumps to some external disk and use it via fixit if you don't wish to mount both drives on the same machine). It would be best to run dump/restore in single user mode, without mounting /usr and /var, or at least with the minimum number of processes running. If you do run on a live filesystem, use the -L flag in dump (I've had some problems with this on large filesystems). Email me if you need more detailed instructions, I am currently investigating this method as a quick installation system for my custom FreeBSD systems. ___ 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"

Actually, the specific reason it crashes is the ruby-18-dbXX module, which also needs to be recompiled. The best way around the problem is to delete portupgrade and everything it depends on, and then reinstall from the ports directly: # pkg_deinstall -Rf portupgrade-2.4.6_4,2 # cd /usr/ports/ports-mgmt/portupgrade # make install # make clean If you do this first, you can then run portupgrade -af, which will recompile ruby and dependencies, but because everything is already recompiled, its compatible and you don't get a crash. > I could do # portupgrade -af again, but this is again "everything" (11 > hours)... Fix portupgrade as shown above, then run something like this: # portupgrade -x ">=2010-06-23" -af This says: "upgrade everything, except those packages installed more recently than 2010-06-23." You should chose the date where you *started* your original portupgrade -af session.

Not really your fault... I suggest you look at the man page for pkg_glob, and look for the kind of glob to supply for portupgrade; for example: The following command line arguments are supported: pkgname_globSpecify one of these: a full pkgname, a pkgname with- out version, or a shell glob pattern to match against pkgnames or their origins in which you can use wild- cards `*', `?', and `[..]', an extended regular expression preceded by a colon `:' to match against pkgnames or their origins, or a date range specifica- tion preceded by either `<' or `>'. So try [ch...@amnesiac]~% sudo portupgrade -f '<2010-06-22' That should reinstall all the ports that were installed before yesterday.
