I know you want to avoid perl, but this kind of problem is it's
sweet spot. The following might be incrementally better (though the
expression to recognize a dotted quad is technically incorrect):
perl -ne '
next unless /^by/;
@f=(split)[1..2];
$_=pop @f;
s/^\D*//g;
s/\D*$//g;
push(@f,$_) if /^(\d{1,3}\.){3}(\d{1,3})$/;
print join( , @f).\n;
'
I'm not fluent enough to translate it but I think awk has all the
required features to do so.

Re: Setup of a software RAID-1 to an existing system?
Johan, The canonical answer is to repost to freebsd-questions, which enjoys a larger readership. But I'll try -- your question is interesting b/c I'm in the same boat, except w/ CURRENT. As you said, breezing through the handbook will show a lot of detail, but perhaps it does not directly address mirroring a live fs. Aside from the handwaving, you might check http://www.vinumvm.org/. There seems to be a relevant (if a little dated) article: http://www.freebsd.org/doc/en_US.ISO8859-1/articles/vinum/index.html It may be possible to mirror partitions, even if half of it is live. Were this not the case, it's prob possible to boot the install cdrom and play some tricks with dd or dump to sync the disks. Perhaps they could then be mounted, vinum set up, and then booted into. It would be fantastic if the freebsd installer had the ability to run raid 1 right out the chute. Doubtless, there's a number of us w/ legacy servers having two disks but no hardware raid. Good luck. Share your notes (at least to newbies) once you get it working!

Hi all! I am pretty new to FreeBSD but thought it might be a nice idea to migrate from a Linux server to a FreeBSD one. My question is regarding software RAID-1 for this FreeBSD box. I have two IDE equally sized hard drives and I installed FreeBSD 4.8 on the other one. Now the question is: can I make a RAID-1 array of these two disks while FreeBSD is installed on the other one (using vinum or other...)? Or how do I get RAID-1 to work on these two disks? I've read some of the vinum documentation but it is unclear to me if it is possible to set up a RAID-1 on a running disk system - and if my assumptions are correct, that it is impossible, it is unclear to me how to set up this RAID-1?

Re: Granting access on MySQL
Konrad Scorciapino wrote: I need to grant a user access to a database. How can I do it? One thing to check is if you need to reload privileges. The mysql doc has lots of info on this. Another short term way to move fwd might be to install webmin or phpMyAdmin, both of which are available in freebsd ports. Tom McIntyre __ Do you Yahoo!? SBC Yahoo!
