Hi, and thanks to everyone that responded to my question regardin encrypted
filesystems. Some of you asked "What are you encrypting" the answer is
backup data on a remote backup server and I am wanting to ensure that it is
safe from prying eyes considering there will be multiple backups from
various companies sitting on the same filesystem.
Thanks again -
Trent

I think some of these mirrors must be badly screwed. I switched to the
Pacific mirror to try it and pulled the "updates" with no problem, but
the "extras" froze, consistently on the same file, the first one to be
downloaded.

Subject: [SLUG] drilling down on disk io stats
Hi all,
How do I work out which processes are writing/reading to my disk - say,
the
last hour or so, maybe the top 10 in terms of frequency and volume. I'm
looking at sar, iostat, lsof for instance. On my system monitor I have
regular, periodic spikes on my disk that seem bigger than normal. How do
I
investigate this sort of thing? Also interested in any recommendations on
reading material for performance tuning and monitoring (security) of
linux-like systems if anyone cares to recommend them.
Thanks,
Daniel

Subject: [SLUG] Encrypted Filesystem
Hi all,
Can anyone recommend an encrypted filesystem technology under linux?
the only one I have heard of is FUSE...does anyone have experience and/or
knowledge of other encrypted filesystem technologies that they would
recommend?

Not sure about drilling down, there might be a plugin for it, but dstat
was really useful for me recently in troubleshooting this type of problem.
http://dag.wieers.com/home-made/dstat/
yeah it looks like dstat_app plugin might do what you want...

Subject: Re: [SLUG] Encrypted Filesystem
I would steer clear of them still. The FUSE ones have the best chance of
support going forward, I suppose though if you really want one.
Truecrypt on loopback is a better option imho...
http://www.truecrypt.org/
at least its going to survive future kernel changes and is cross platform

Subject: Re: [SLUG] Encrypted Filesystem
It depends what you want to encrypt.
On my laptop I use encfs and have a target folder in Desktop into which
I can mount the encrypted directory, which is a .filename structure. I
can optionally mount it with a timeout so that if I leave my lappy for a
while then the visible directory will be unmounted. Even root cannot
see the encrypted filesystem, only the owning user can do so. It suits
my needs, but if you want something with a broader scope then you might
need to look at dm-crypt or something similar.

In lieu of more appropriate and expert advice from someone else on
list, I could offer some suggestions though they may not address your
hardware/dev issue.
What do you get when you run iwconfig ?
Also, what's in /proc/net/wireless?
What's in your /etc/modprobe.d/ipwXXXX file?
You could kill ipwXXXX and ipwXXXXd the regulatory daemon - just as an
experiment, then try to start them up again and look for errors.
Maybe they start up more reliably after the boot - I have no idea.
On my working system:
[EMAIL PROTECTED]:init.d$ ps -ef | grep -i ipw
root 3118 11 0 15:33 ? 00:00:00 [ipw3945/0]
root 3119 11 0 15:33 ? 00:00:00 [ipw3945/1]
root 3120 11 0 15:33 ? 00:00:00 [ipw3945/0]
root 3121 11 0 15:33 ? 00:00:00 [ipw3945/1]
root 3295 1 0 15:33 ? 00:00:19 /sbin/
ipw3945d-2.6.17-11-generic --quiet
As an experiment, I removed the ipw3945 module using rmmod (maybe
modprob -r is more appropriate) and killed off the daemon using the --
kill option to the above /sbin program.
I don't get eth1 showing up at all in ifconfig or iwconfig until I
'modprobe ipw3945' which brings back the above [ipw3945/x] processes.
It also starts the ipw3945d daemon.
I then invoke wpa_supplicant and configure it for eth1:
wpa_supplicant -ieth1 -c/etc/wpa_supplicant/wpa_supplicant.conf -Dwext
-w -B
(You may have to ifconfig your eth1 interface and set up your routing
tables again to get connected)
HTH - in some tangential way, perhaps :)

I'm not exactly sure what you are asking <sorry> but if you want to see
network the neighborhood on your ubuntu box and have samba up-n-running
and
suitable shares mapped then
you must provide a login passwd, typically
smbpasswd -a me-or-other
secret
secret
Also choose the same workgroup for all systems eg WORKGROUP, MSHOME TUX
etc
Then when you access network->all networks->WORKGROUP as me-or-other and
secret you have access.
You may also specify public shares and have no login requirements typical
eg /tmp
swat makes this easy for a newby, but don't bother its too hard to make it
work on ubuntu!

Hi all,
Sorry I did not make myself clear.
I have several Win98 PCs on a LAN.
One is dual-boot running Ubuntu 6.06 as well as Win98.
In Ubuntu I can see and access (read/write/execute) all files on all PCs
including th Win98 partitions on the Ubuntu PC. (that is I can see and
access the whole LAN)
All the PCs on the LAN, including the Ubumtu OS, are defined in a
workgroup
called WORKGROUP
On the other PCs (running only Win98) I can see the PC running Ubuntu (it
shows up in Network Neighbourhood)but if I try to access the Ubuntu PC
from
one of the Win98 PCs I get a message on the Win98 PC saying
" requires password to "resource \\MAC2\IPC$" "
Any further advice?
Mac from the Mountains
