Anyone got any recommendations or experiences with Haswell laptops
running Linux yet?
Thinking that it might be time to refresh my work laptop and a Haswell
Ultrabook could be quite enticing..

iptables-save on rhel5 outputs:
-A RH-Firewall-1-INPUT -s 220.127.116.11/255.255.0.0 -p tcp -m tcp -j ACCEPT
whereas rhel6 outputs
-A RH-Firewall-1-INPUT -s 18.104.22.168/16 -p tcp -m tcp -j ACCEPT
Wanting to normalise iptables-save to one form or the other (preferably
using the dotted quad netmask), the best I can come up with is a line by
line grep (for optimisation perhaps, since a match wont happen often) for
/<number> and then extract the number, pass to cidr2mask, and replace
/<number> in that line (this is part of a self contained shell script that
will be executed on the fly on another host, so I'd rather not rely on
anything that isn't already in RHEL, ie no writing a perl sript myself
unless it's a one liner perl -e thing).
What flag to iptables-save am I missing where it does this for me?
Just got what looks to be a pretty good deal on what appears to have
GPL version of the code made available.
Got this D-Link Modem - hopes weren't high but it appears pretty
reasonable 802.11bgn + 8 LAN ports switch + WAN router.
I noticed that it contained a "D-LINK GPL Code Statement" with link
which turns out to be their GPL web interface which lists masses of
products and a download links to source code
which includes my DIR-632 (took a little time to find it amongst the
massive number of items).
I am downloading it now - 185Mb. See what you actually get in that.
The modem itself is rather nice - it has most features you could think
of (no CLI though, Web interface) and has a
built in manual that explains each feature in detail!
I suspect they are letting them go at that price because the new
802.11ac modems have arrived.
for the original promotion.
Anyway thought others might be interested in this and perhaps an
example of GPL compliance that seems pretty good...
At the risk of starting a thread that runs for months, how do you overcome microsoft FUB in the education sector.
I've just quoted a couple of machines for a local, not for profit, school up my way that were intended to run KVM and file services with Winblows servers on top of them "because they have to have windows").
The Buresr, whom I do have some sympathy for, given the amount of crap he's been told, has made the decision that Linux is 'too risky', after consulting other bursers on some network of bursers (god knows) and being advised that "Linux is no good in an education environment, can't get staff, no-one uses it except a few 'out there risk takers'". Of course the M$ suppliers are pushing the same line.
How the hell do you combat this bull shit?
I have to say I'm amazed that a school with so little money is happy to throw it away to M$ (despite the heavy discounts they get for the licenses).
I want to create a filesystem to store my on-disk backups (from Bacula) on a new server. These backup files will be few (less than 10000) and mostly huge (>1GB). Because I will have multiple files being written out at once, a large data per inode ratio seems to make sense as it will greatly reduce fragmentation, and wasted space would be low because of the small number of files. Also because the write pattern is exclusively streaming writes, I can go against my normal rule and use RAID5.
I've chosen a 4MB of data per inode ratio based on some rough calculations, but while my mkfs.ext3 <dev> -i 4194304 just raced through initially, when it got to "Writing superblocks and filesystem accounting information:" it just seemed to hang. Strace says it's doing seek, write 4k, seek, write 4k, over and over again. I hit ^C and the process is now [mkfs.ext3], but the system is still pegged at 100% disk utilisation.
Any suggestions as to how I could make this go faster? The filesystem is around 8TB (RAID5 of 4 x 3TB disks), so it's not exactly small, and the disks are only 7200RPM SATA, but I know xfs would complete pretty quick. I'd use xfs but over the years I've used xfs and ext3 in roughly equal proportions, and I've lost 3 xfs filesystems and no ext3 filesystems, so I'm a little reluctant to commit to it.
I have this crazy problem and I hope it is possible.
Part in my script:
svnadmin dump -r1:100 --incremental /srv/my_repo > /srv/my_repo.1-100.dump
* Dumped revision 1.
* Dumped revision 2.
* Dumped revision 3.
* Dumped revision 4.
* Dumped revision 5.
* Dumped revision 6.
* Dumped revision 7.
* Dumped revision 8.
* Dumped revision 9.
* Dumped revision 10.
Now I want to store the output (standard out/error) to a log file for
future reference using this:
svnadmin dump -r1:100 --incremental /srv/my_repo > /srv/my_repo.1-100.dump
| tee /srv/my_repo.1-100.log
But seems not to work. Is this doable with bash or python?
is someone here familiar with Samnba 4 and especially the samba-tool
written in Python?
The story so far: Samba4 can work with ZFS, and is able to use the
The trap: the samba-tool provisioning script does not work with ZFS.
Reason according to Andrew Bartlett a few days ago:
"The issue is essentially that the python-based provision code need to
detect the use of zfs, load the zfsacl module in the generated smb.conf,
and instead of testing simple posix ACLs, proceed to setting a full NT
ACL when we create the sysvol share."
I am not familiar with python but had some limited success in reading
Anyway, a look at lib/python2.7/site-packages/samba/provision/__init__.py
let me suggest that I may
- test whether zfs is there (e.g using libc.getvfsbyname("zfs", byref(info))
- add lines as "nt acl support = yes"
into the smb.conf
- load the zfs_acl.so module (how?)
- modify the test when creating the SysVol
(at the moment smbd.set_simple_acls)
I wonder whether anyone could help a bit.
My main problem is the loading of the module. I could not figure out
how to do it, especially what's the proper "Samba way".
Thanks for help

Not too good, see below.

"chroot: failed to run command '/bin/bash': no such file or directory"
So, it would seem that I'm missing something.
When you said "Try to mount all your partition under /mnt and run chroot"
did you imply some other things needed to be done that you didn't list?
As I said I am using Knoppix live, which is a 32 bit version. The system
I'm trying to rescue is 64 bit. Is that an issue?
In an attempt to see if I could get a bit further I booted a 64 bit system
in rescue mode, but that doesn't provide grub.

I have a production PC running LMDE that I will need to upgrade at some
point, a process that will include the same jump from grub-legacy to
grub-pc as you've just fought with.
Might leave it until the weekend!
Vote NO in referenda.
I've got the LUV Makerbot Replicator working, I will demo it at some meetings
some time soon.
One problem I'm having is that the model in progress will often get detached
from the platform. The "Calibration Dual" model file that ships with the
replicator has become detached three times, each time the front left corner
lifts from the platform first and then eventually it all comes unstuck and the
model is destroyed. I tried the "Cube Slide" model file that ships with it
once and it detached when it was on the last black segment, so the model was
mostly OK but it's still not a successful result.
Any suggestions for how to deal with this?
