Re: linux malware

[Lisa Kachold]

Using antivirus software is recommended, however many desktop users will be
surprised to learn that they are actually part of a botnet transmitting
virus or other information.  A good check would include all packet traffic
out from the desktop, and a quick look at "lsof":

Yes,

Malware exists that targets linux indirectly (as in browser and Adobe
based) and directly.

Check out the online registry:  http://www.team-cymru.org/Services/MHR/

Hello Free Geek regulars!

Please join us Tuesday 12.04.12 from 6pm to 9pm at Free Geek to celebrate
the Winter holiday as well as Free Geek's release of Xubuntu 12.04!

We will have a fabulous taco bar and encourage you to bring side dishes or
desserts to compliment.

There will be a White Elephant Gift Exchange--for those that don't know a
White Elephant Gift is something silly, re-gifted, or ironic that you
already have wrapped up for a fun exchange, only folks who bring will
participate.

DISCO rhymes with DISTRO and well were gonna dress up in 70's gear and
play that funky music, so come ready to groove!

There will likely be Distro related games and of course all around fun.

This is a big thanks for all your hard work Volunteers!

There will be more details to come, please save the date and join us!

Thanks!
Misty the elf

Re: Linux in China?

[Lisa Kachold]

There are a few problems with trying to get accurate Linux numbers:

1. Many Linux users dual-boot with Windows, so do they count as 1/2 a Linux
user? Or do they get counted twice (once for Linux, once for Windows)?

2. Linux doesn't have any sales figures for home users (and even for many
servers), unlike Mac OS X and Windows.

3. Many Linux users choose to mask or hide their online identities, either
for anonymity or to get proper functionality from certain Internet
Explorer-only websites.

4. Many Linux users have multiple computers (so does each computer owned
count as a Linux user or is that one person a Linux user?).

Perhaps we should create a massive [Chinese] spam campaign that installs a
bot-net to infect with http://sourceforge.net/projects/statix/ and track
Linux desktops?

Our concept of the culture of China and "linux use" is based entirely upon
our American consideration that every family (and individual) has a
"personal computer".  In China, it's more common for only a small
percentage of the upper middle class families to have ONE  "personal
phone", smartphone or tablet.

Computer *ownership* is now at about 4-5% of the worlds population. However
with many social projects putting computers in villages in developing
countries between 12-14% of the worlds population have access to a
computer. Approx 3-5 % of the worlds population have internet access.   To
put this into context only about 25% of the worlds population sleep in
their own bed at night and only about 30% of the worlds population are rich
enough to have a bank account!

 China's "Internet population" is touted to be 415.6 million. This figure
includes people who access the Web through Internet cafes or public
computers and smartphones.

Scientific and development based internet use (therefore much of Linux) is
strictly controlled in China.

W3Counter http://www.w3counter.com/globalstats.php has linux use as 1.8 %,
of course that's not China.

It's OT, discard it if you don't like it.

I fear it's far too late.

In no current political party do we find that our idealogy actually pencils
out to actualization of our stated goals.

We are already enslaved.

Re: Cannot remove a widget

What is the widget name and installation instructions?

For instance, this widget is installed with an apt-get command and some
custom editing, therefore an apt-get remove will uninstall it?

If it is working, it is a derivative of this or another bug.  I would

Re: OT: How to attach an image -- Thanks

[Lisa Kachold]

vCard is the abbreviation for Virtual Business Card (.vcf file), the
standard for creating and sharing contact information over the Internet.
you can send a contact to another person by forwarding it in vCard format.
A recipient who uses an email and personal information manager program that
supports vCards, such as Entourage, can open the vCard and add the contact
to his or her address book.

PLUG Hackfest TODAY 11AM-2PM 11/10/2012 DeVry Phoenix

[Lisa Kachold]

We have a great Hackfest for you this Saturday at DeVry University in
Phoenix from 11AM -2PM.

Scott Becerra and a behind the scenes contributer named Ruben, have built
up a very holy system for our edification and elucidation!
Ruben is an awesome pen tester; he's discovered several vulnerabilities and
has contributed to the metasploit project.
You can check out his website at http://www.thehackerin.me/

You can also check out Scott's site at
:http://www.thriftstorehacker.**com/

The first half of the meeting will be pen-testing; where we assist everyone
to do recon and investigation, use tools and evaluate the target.

The last half of the meeting we walk through the process of discovery and
exploitation to help those that may still be stuck. Our goal is to design
it so that there are easy, medium and more difficult flags and any needed
tools are already included with Backtrack5r3.

We have a good number of flags, easily won with Backtrack5r3 DVD live disks
you can pickup and use in the lab machines.

We have ready willing and able team members ready to jump in and assist you
in your attack(s).

We also have room for Open Discussion, Spectators, and those who want to
watch or copy various DefCon 20 materials.

We have resurrected the Dummy Drills - Answer a (hard) question (from David
Demland - Adjutant Professor) (or capture a flag) and get an "Anatomy of a
Linux Hacker" Tee shirt FREE.

That's an interesting response, however fraught with consequences.

First year computer science students are often asked, as flow charting
exercise, to model "ethics" in society.  Golden Rule, Turn the Other Cheek,
Hit Back with a Bigger Hammer, are all modeled into a virtual society.
 Interestingly in this exercise, which do you think was found to be most
successful?

Yes, it is "Hit Back with a Bigger Hammer"

Of course, the only part that was not modeled was the consequences of the
law, assuming that if there was no law available to resolve the problem,
there would be no consequences.

There are things that can be done with regards to various types of scammers:

1) These scams can be reported to various authorities:

http://www.ripoffreport.com/directory/global-resorts-network.aspx

http://www.consumerfraudreporting.org/FBI_LocalOffices.php

2) Tracking via cookies

Setting tracking cookies in response email can provide additional
information related to the end source.   Many people will be surprised to
learn they are actually originating in the US but hopscotching to other
countries to reduce the chances of their arrest.

3) Depending on the scam, scam the scammers (aka scambaiting):

http://www.troyhunt.com/2012/02/scamming-scammers-catching-virus-call.html

http://www.419eater.com/

There are various discussions of how to straddle that thin grey line
between joining the criminal and staying in the solution.

SMB - not SMB2, right?
Upgrade that Vmware to ESXi.

Microsoft 7 uses smb 2.2, btw --> protocol step down might add to the lag?
What is your smb version on each node? CIFS clients?

http://www.codefx.com/CIFS_Explained.htm

A given client and server may implement different sets of protocol
variations which they negotiate before starting a session.

There are a great many considerations for this problem:

0) Samba in VMware:
http://www.vmware.com/support/ws45/doc/network_samba_ws.html

1) Active .vs Passive FTP:
http://www.youtube.com/watch?v=bqrlBicM8lE

2) Disk type:

Dynamically allocated VMware virtual disks are extremely slow with writes.
 Huge virual disks over say 300 gb are also really really slow for writes.
Raid 5 or greater on VVware is also extremely slow with writes, depending
on the version of VMware.

3) What kind of network are you using?

By default there are three virtual networks created on a VMware server.
They are: VMnet0 – Bridged VMnet1 – Host-only VMnet8 – NAT

4) Networking UDP packets for SMB:

SMB uses UDP which is a connection-less protocol. In other words it simply
broadcasts.

UDP uses a simple communication model without implicit transmission checks
for guaranteeing reliability, sequencing, or datagram integrity. Though
these factors might seem to suggest that UDP is not a useful protocol, it
is still widely used in particular areas where speed, more than
reliability, is of utmost importance. With UDP, error checks and
corrections are carried out in the communicating application, not at the
network layer. However, if error checks and corrections are needed at the
network layer, the application can use Transmission Control Protocol (TCP)
or Stream Control Transmission Protocol (SCTP), which are specifically
formulated for this reason.  Since UDP does not have the overhead of
checking whether the data has reached the destination every time it is
sent, it makes the protocol that much faster and more efficient. UDP is
often used for time sensitive applications where missing data is preferred
to late arriving data.

UDP packets can also create broadcast storms (NFS 3), therefore it's not
suggested that SMB or  older NFS3

5) Putting it all together: Using Samba for File Sharing on a Host-only
Network

On a Linux host computer, VMware ESX Server can automatically install and
configure a Samba server to act as a file server for Microsoft Windows
guest operating systems. You can then use Windows Explorer in the virtual
machine to move and copy files between virtual machine and host — or
between virtual machines on the same network — just as you would with files
on physical computers that share a network connection.

The lightly modified Samba server installed by VMware ESX Server runs over
the VMware ESX Server virtual Ethernet and the Samba traffic between
different operating systems is isolated from actual local area networks.
The source code diffs for the changes, based on Samba 2.0.6, are available
from VMware.
Adding User Names and Passwords to the VMware ESX Server Samba Password File

You may add user names and passwords to the VMware ESX Server Samba
password file at any time from a terminal window on your Linux host
computer.

   1. Log in to the root account by typing the following command at the
   prompt:
   su

   2. Run the VMware ESX Server Samba password command.
   vmware-smbpasswd vmnet1 -a 

   where  is the user name you want to add.
   3. Follow the instructions on the screen.

   *Note:* vmware-smbpasswd is based on the standard Samba password
   program. If you are familiar with the options used in smbpasswd, you may
   use any of them in vmware-smbpasswd.
   4. Log out of the root account.
   exit

   If you receive an error message that says

Great link!

It's always better to run Win as a virtual appliance under Linux!  Call it

Hakin9.org Security Professional Submissions

[Lisa Kachold]

Anyone interested in submitting content to an online security zine?

There's onging negative critique of Hackin9.org on Twitter from the deep
dark security underground, mostly due to the nature of the costly
commercial online rag, well known for phishing/spamming security
professionals of note with invitations for articles  (for which Hackin9.org
does not provide remuneration ).
 In classic online zine fashion, sec pros and reverse engineers have been
happily submitting excellent content just for the venue for their work and
wide audience.   Check out the content and professionalism of Hackin9.org
(as well as subscription costs) and decide for yourselves?

Here's the contact for submission:

Re: cut for compromised boxen?

[Lisa Kachold]

Hans,

This type of insecurity is rampant in all arenas of Internet accessible
mismanaged networks or mis-implemented systems.  It's not just Micro$not;
it's not just the startups or the non-technical; interestingly it is
historically this bad, and simply continues despite our forward race down
the information SuperDirtway!

We have identified the enemy, and it is us!

Laugh!

But the nature of profit DOES contribute to it!

Smartd is known to be buggy under certain distro releases and with certain
drives and controllers.

Running /usr/sbin/smartctl -H /dev/hda, will tell you if the drive passes
the health check, however, the ultimate test of the drive is via drive
testing utilities and you will see there are no errors on the disks.
 [PLEASE POST the OUTPUT to smartctl HERE]!

In these cases, everyone turns off smartd reporting, while leaving kernel
critical messages escalated to the console.

However, before we make assumptions, we need to see your smartctl output;
this could also be an issue with your hardware controller, motherboard,
unconditioned power or power supply.  We would also want to evaluate your
exact errors against known smartd issues of your distro version.

You can get php plugins or apps that will provide a "Like" button on
Facebank.  I would go ahead and use it.

You can enable iptables to do this:

http://www.cyberciti.biz/faq/linux-configuring-ip-traffic-accounting/

It should look like this:

iptables -N INET_OUT
iptables -N INET_IN
iptables -A FORWARD -j INET_IN
iptables -A FORWARD -j INET_OUT
iptables -A INPUT -j INET_IN
iptables -A OUTPUT -j INET_OUT

To see your data:

iptables -L -v -n

To see just your In:

/sbin/iptables -v -n -L INET_IN

To see just your Out:

/sbin/iptables -v -n -L INET_OUT

Depending on your distro, your iptables files will be saved in a directory.

You can use:

iptables-save

to save the recipe to persistent state (past a reboot or reset).

You can specify custom applications; use Applications; set custom variables
and more:

 From:  http://blog.bodhizazen.net/linux/firewall-ubuntu-servers/

As an example, /etc/ufw/applications.d/apache2.2-common contains

[Apache]
title=Web Server
description=Apache v2 is the next generation of the omnipresent Apache web
server.
ports=80/tcp

[Apache Secure]
title=Web Server (HTTPS)
description=Apache v2 is the next generation of the omnipresent Apache web
server.
ports=443/tcp

[Apache Full]
title=Web Server (HTTP,HTTPS)
description=Apache v2 is the next generation of the omnipresent Apache web
server.
ports=80,443/tcp

Well,

1.   dbus issues: Resolve by deleting ~/.dbus*
2.   Permissions: Press alt + F2 and type gksu gedit to verify or run via

3.   Issues with file corruption: sudo touch /forcefsck && sudo reboot

UFW  rule:

*advanced allow example for allowing access from an ip address range
10.120.0.1 - 10.120.0.255 to port 22*
sudo ufw allow from 10.0.0.0/24 to any port 22

you want to block access to port 22 from 192.168.0.1 and 192.168.0.7 but
allow all other 192.168.0.x IPs to have access to port 22

Code:

sudo ufw deny from 192.168.0.1 to any port 22
sudo ufw deny from 192.168.0.7 to any port 22
sudo ufw allow from 192.168.0.0/24 to any port 22

if you do the allow statement before either of the deny statements it will
be matched first and the deny will not be evaluated.

you can check this by checking ufw status
Code:

sudo ufw status
To Action  From
-- --  
22:tcp DENY192.168.0.1
22:udp DENY192.168.0.1
22:tcp DENY192.168.0.7
22:udp DENY192.168.0.7
22:tcp ALLOW   192.168.0.0/24
22:udp ALLOW   192.168.0.0/24

the allow is at the bottom and will be the last command evaluated if it
appeared above the deny rules the deny rules would not be evaluated.

Re: gimp 2.8

[Lisa Kachold]

Well, actually, Mike (/all), I think it goes a bit further than this.

I don't learn by rote memorization.  I could not learn to read by rote
memorization; I had to have phonix or a rule based associative way of
translation of symbols in order to read.

I learn by context.  I learn by assimilation.  I can learn by reading, but
my technical reading is done without the expectation that I will memorize
each and every thing immediately.  What I do instead is get a vague idea
and a knowledge of where I can find what another would obtain through rote
memorization.

It's a complete way of seeing common to our caste.  We have transcended the
day of having to obtain a degree in a subject in order to master it.   The
sheer number of changing details is huge.

For gimp for instance, your going to want to know how to use the tools.  In
order to do this, the best way is simply by doing, don't you agree?

I did some work for some that were hosted there.  And in the old days used
them for offsite second (not sure if they still provide that service).
 They were reliable.

http://www.webhostingtalk.com/archive/index.php/t-875904.html  Others think
so too.

Why are you moving?

GoDaddy has some really nice services that aren't going to be available
everywhere, like URL forwarding, etc.

Do you like cPanel?  (If you are moving your webhosts also)

It has to do with the specifications between USB 1.0 and 2.0 which require
different power where the cables must also contain that capacity.

Named installs easily.

Setting up a split dns profile is easy, but it would actually be better if
you have a subnet of IP addresses?

No, it doesn't consume alot of bandwidth, since it's on the local net, it
will reduce you inbound/outbound bandwidth.

You can expand it for better performance, but I doubt that your utilization
issues are /dev/shm kernel intermessage processing related.  In a J2EE
system, it would be memory, garbage collection, or a kernel based known
memory error.

But if you are running Ultramonkey  or a databasae, you could use all of
/dev/shm during heavy network use, so you can easily expand /dev/shm (see
below).

performance.
On heavily loaded system, it can make tons of difference. For example
VMware workstation/server can be optimized to improve your Linux host's
performance (i.e. improve the performance of your virtual machines).

In this example, remount /dev/shm with 8G size as follows:
# mount -o remount,size=8G /dev/shm
To be frank, if you have more than 2GB RAM + multiple Virtual
machines,
this hack always improves performance. In this example, you will give you
tmpfs instance on /disk2/tmpfs which can allocate 5GB RAM/SWAP in 5K inodes
and it is only accessible by root:
# mount -t tmpfs -o size=5G,nr_inodes=5k,mode=700 tmpfs /disk2/tmpfs
Where,

   - *-o opt1,opt2 * : Pass various options with a -o flag followed by a
   comma separated string of options. In this examples, I used the following
   options:
  - *remount* : Attempt to remount an already-mounted filesystem. In
  this example, remount the system and increase its size.
  - *size=8G or size=5G* : Override default maximum size of the
  /dev/shm filesystem. he size is given in bytes, and rounded up to entire
  pages. The default is half of the memory. The size parameter
also accepts a
  suffix % to limit this tmpfs instance to that percentage of your pysical
  RAM: the default, when neither size nor nr_blocks is specified, is
  size=50%. In this example it is set to 8GiB or 5GiB. The tmpfs mount
  options for sizing ( size, nr_blocks, and nr_inodes) accept a suffix k, m
  or g for Ki, Mi, Gi (binary kilo, mega and giga) and can be changed on
  remount.
  - *nr_inodes=5k* : The maximum number of inodes for this instance.
  The default is half of the number of your physical RAM pages, or (on a
  machine with highmem) the number of lowmem RAM pages, whichever is the
  lower.
  - *mode=700* : Set initial permissions of the root directory.
  - *tmpfs* : Tmpfs is a file system which keeps all files in virtual
  memory.

*How do I restrict or modify size of /dev/shm permanently?*

You need to add or modify entry in /etc/fstab file so that system can read
it after the reboot. Edit, /etc/fstab as a root user, enter:
# vi /etc/fstab
Append or modify /dev/shm entry as follows to set size to 8G

none  /dev/shmtmpfs   defaults,size=8G0 0

Save and close the file. For the changes to take effect immediately remount
/dev/shm:
# mount -o remount /dev/shm

Fwd: Hackfest 11AM-2PM Saturday September 8 DeVry Phoenix - Backtrack5 r3 Eval with Free DVD

[Lisa Kachold]

Hackfest today 11AM-2PM in our new location at DeVry University on the
second floor.

We will be previewing Backtrack5r3 - new features.  We might have
VirtualBox flags, but we will be concentrating on assist everyone to get a
USB or DVD setup for your festing fun. I will be giving out DVD's with
BT5r3.

Sorry we don't have the DEFCON 20 vids yet. There are some online, but not
as good as the commercial ones coming thanks to Ben Trussell - ASU.

We have a great number of Cisco devices to exploit at the facility - all
unpatched.  We will go over how to Network Discovery and more, depending on
time.

Are you a Gimp?
We have a TeeShirt Design Contest also.  The winner will get a USB drive
and a TeeShirt free.

See you at DeVry!

Re: Firefox screen font size too small and unstable

I don't think this is the Firefox users group, do you?

They have forums there for these questions?

Re: System crash - now shows "no space on device"

[Lisa Kachold]

Hi Joe,

You can check your free inodes via:

# df -i
or via:

# tune2fs -l /dev/sdb1 | grep *Free

*
Boot your system into single user mode:
Is this Fedora? Use F15 or append the word "single" to the end the grub2
command line.

and delete all the files in;

/var/spool/mail/root
/var/log/messages
/var/log/mail*
/var/log/mess*

Look for core files - but until you clear up some space you can't do much
(not even locate).  Did you determine if your disk is mounted read only?
Do you have a hardware controller or any mdadm on the drive?

You can boot into Knoppix and it will not mount any part of the disk as
swap so you can work on the drive after manually mounting it.

You can also use yum or apt-get to remove a package to quickly get some
diskspace free.

Use locate (find-utils) to identify and remove core files, iso's and
Virtualbox images.  But you can't run find or locate without /tmp file
space.

Again, removing the root mail spool (be sure to create it again with "touch
/var/spool/mail/root | chown root:mail /var/spool/mail/root"

# locate core

You can also determine what files were modified 2 days ago:

touch -t 201209172359 dummy
find / -name 'DS*' -newer dummy



Once you have enough disk space free you can boot back into kde.

You should see the connection as "bridged" on your network, not NAT, from
whatever you are using (Oracle Virtualbox) for this virtual.

Then you can enter:

/etc/init.d/network start

Reference:  http://www.linuxfromscratch.org/lfs/view/7.0/scripts/apds18.html

/etc/sysconfig/ifconfig contains the list of all the interfaces.

Once the network is verified and setup with bridged mode, you need to start
OpenSSH

/etc/init.d/sshd start

/sbin/chkconfig sshd on 3 4 5

And you might also look at your /etc/ssh/sshd_config file to be sure you
allow root ssh?  Search forward for "Root".

Make change and restart sshd

/etc/init.d/sshd restart

Also, you might add the other server to your /etc/hosts file and
/etc/hosts.allow file

http://www.linuxfromscratch.org/blfs/view/6.3/server/openssh.html

Make sure your directory permissions are good for .ssh and your ssh-keygen
is setup as explained in the reference link.

Yes, mine is still in the free stage. But I do get charged if I do a lot of

Re: Making Dir writable by WordPress

[Lisa Kachold]

Postscript:

You can use HTEXPLOIT to bypass any .htaccess permissions:

HTExploit is an open-source tool written in Python that exploits a weakness
in the way that htaccess files can be configured to protect a web directory
with an authentication process. By using this tool anyone would be able to
list the contents of a directory protected this way, bypassing the
authentication process.

Sorry,

It's in the /var/log directory or whatever you have configured as log-level
4 in /etc/syslog.conf for kernel messages:

Here's an explanation of the log levels:

-l 9 = error
-l 8 = panic
-l 7 = debug
-l 6 = info
-l 5 = notice
-l 4 =warning

This example is log level 7:

 Code:

kern.=debug /var/log/firewall

If the "log-level" specified in iptables entry is the "debug" level (7),
then the syslog.conf file example above reflects this fact and sets up the
file /var/log/firewall to capture all of these messages. To invoke issue a
"/sbin/service syslog restart", and then the file "/var/log/firewall" will
appear, and happily start filling up.

If you don't have any website on that server and are not allowing user
shell or xterm accounts, you are probably fine.

Known Issue:  Wordpress asks for a directory location: you set it up as 755
and it won't work.

Wordpress works, of course, from PHP and Apache.  So in order to allow for
Apache ftp you would need to make it writable by Apache and other.If
you change the group writable permissions your ftp breaks (so don't do
that!):

Here's more on it:
http://wordpress.org/support/topic/advanced-problem-image-upload

http://wordpress.org/support/topic/151290

Solution:

You need to use "chmod 777" for uploads to work.

Security Issues:

This is a security risk of course, since there are many spider scrapers
looking for an open permission directory to be able to write, say a fake
Phishing Site page for UPS with an email results script.

Solution: (from Wordpress documentation):

Base image directory

The base image directory must be world writable i.e.: chmod 777
Base image URL

The URL to the base image directory, the web browser needs to be able to
see it.

Note that the directory can be protected via .htaccess on apache; check
your web server documentation for further information on directory
protection. If this directory has to be publicly accessible, remove
scripting capabilities for this directory (i.e. disable PHP, Perl, CGI). We
only want to store images in this directory and its subdirectories.

On apache you can create the following .htaccess file in your base image
directory:


   order deny allow
   deny from all

If you do in fact have a Nehalem it is non-ecc.

Be sure you have populated your dimms in the right pairs.

Buy some from a supply that allows returns?

Re: firewall

[Lisa Kachold]

Hi Derek,

How are you?

We didn't really cover if you are using a singular dsl device or a small
switch/dsl modem on the upstream?

So if you have your two boxes (Ladmo and Wallace) connected via a crossover
cable or small switch to eth1 on Wallace which has eth0 connected to your
dsl, that's good.

If you have both boxes connected to the dsl switch/modem, there might be a
problem?

The best way to verify your settings is via nmap from outside.

Assumptions without real tests are the basis of bad security everywhere.

nmap each server from the other server.  Run a nmap from a shell or linux
box externally.

Also run this tool on the Windows system to verify what is really running:

Adding a list of RFC 1419 private ip addresses might be nice but if you
tighten up your nat masquerade rule, they won't be necessary.

Also, if you can access the web via port 443, I would be worried that you
are getting packets from a switch on the other port eth1 outbound/inbound?

Test it...

It looks like you just have the wrong:

>From Wikipedia:
Nehalem microarchitecture based
Main article: Nehalem
(microarchitecture)

With the release of the *Nehalem
microarchitecture
* in November 
2008,[14]Intel
introduced a new naming scheme for its Core processors. There are
three variants, Core i3, Core i5, and Core i7, but the names no longer
correspond to specific technical features like the number of cores.
Instead, the brand is now divided from low-level (i3), through mid-range
(i5) to high-end performance
(i7),[15]which
correspond to three to five stars in Intel's Intel Processor Rating
[16]  as opposed to
the entry-level Celeron (one star) and Pentium (two stars)
processors.[17]Common
features of all Nehalem based processors include an integrated DDR3
memory controller as well as QuickPath
Interconnector
PCI
Express  and Direct Media
Interface  on the
processor replacing the aging quad-pumped Front Side
Busused in all earlier
Core processors. Also, all these processors have 256 KB
L2 cache per core, plus up to 12 MB shared level 3 cache. Because of the
new I/O interconnect, chipsets and mainboards from previous generations can
no longer be used with Nehalem based processors.
 Core i3

The *Core i3* was intended to be the new low end of the performance
processor line from Intel , following
the retirement of the Core 2 brand.
[18] 
[19]

The first Core i3 processors were launched on January 7,
2010.[20]

The first Nehalem based Core i3 was
Clarkdale-based,
with an integrated GPU  and two
cores.[21]The
same processor is also available as Core i5 and Pentium, with slightly
different configurations.

The Core i3-3xxM processors are based on
Arrandale,
the mobile version of the Clarkdale desktop processor. They are similar to
the Core i5-4xx series but running at lower clock speeds and without Turbo
Boost 
.[22]According
to an Intel
FAQ  they do not support Error Correction
Code (ECC) memory
.[23]According
to motherboard manufacturer Supermicro, if a Core i3 processor is
used with a server chipset platform such as Intel 3400/3420/3450, the CPU
will support ECC with
UDIMM.[24]When
asked, Intel confirmed that, although the Intel 5 series chipset
supports non-ECC memory only with the Core i5 or i3 processors, using those
processors on a motherboard with 3400 series chipsets it will support the
ECC function of ECC
memory.[25]A
limited number of motherboards by other companies also support ECC
with
Intel Core iX processors; the Asus P8B WS is an example, but it does not
support ECC memory under Windows non-server operating
systems.[26]
You HAVE to have some information on that mobo?  It should be a
Supermicro.

As far as I can tell, your non-ecc is the correct memory.

Dell Streak AT&T.

I had a Verizon USB modem in the old days when you had to recompile the
kernel on Ubuntu to use it with USB, but I really don't think the expense
is worth it, anymore, due to phone tethering.

Re: Remote login... Oh Boy

[Lisa Kachold]

Set your local display variable and if the ports are open and OpenX is
running, you will get an echoed Xterminal session to open locally.  If you
are using Windows locally, you will need an Xcapable SSH client like
Hummingbird.

An X program needs two pieces of information in order to connect to an X
display.

   -

   It needs the address of the display, which is typically :0 when you're
   logged in locally or :10, :11, etc. when you're logged in remotely (but
   the number can change depending on how many X connections are active). The
   address of the display is normally indicated in the DISPLAY environment
   variable.
   -

   It needs the password for the display. X display passwords are called *magic
   cookies*. Magic cookies are not specified directly: they are always
   stored in X authority files, which are a collection of records of the form
   “display :42 has cookie 123456”. The X authority file is normally
   indicated in the XAUTHORITY environment variable. If $XAUTHORITY is not
   set, programs use ~/.Xauthority.

You're trying to act on the windows that are displayed on your desktop. If
you're the only person using your desktop machine, it's very likely that
the display name is :0. Finding the location of the X authority file is
harder, because with gdm as set up under Debian squeeze or Ubuntu 10.04,
it's in a file with a randomly generated name. (You had no problem before
because earlier versions of gdm used the default setting, i.e. cookies
stored in ~/.Xauthority.)
Getting the values of the variables

Here are a few ways to obtain the values of DISPLAY and XAUTHORITY:

   -

   You can systematically start a screen session from your desktop, perhaps
   automatically in your login scripts (from ~/.profile; but do it only if
   logging in under X: test if DISPLAY is set to a value beginning
with :(that should cover all the cases you're likely to encounter)).
In
   ~/.profile:

   case $DISPLAY in
 :*) screen -S local -d -m;;
   esac

   Then, in the ssh session:

   screen -d -r local

   -

   You could also save the values of DISPLAY and XAUTHORITY in a file and
   recall the values. In ~/.profile:

   case $DISPLAY in
 :*) export | grep -E ' (DISPLAY|XAUTHORITY)='
>~/.local-display-coordinates.sh;;
   esac

   In the ssh session:

   . ~/.local-display-coordinates.sh
   screen

   -

   You could detect the values of DISPLAY and XAUTHORITY from a running
   process. This is harder to automate. You have to figure out the PID of a
   process that's connected to the display you want to work on, then get the
   environment variables from /proc/$pid/environ (eval export

Re: iptables. 32 or 64?

That is, of course, depending on his hardware and distro?

Hi!

Great question:

32-bit iptables doesn't work on a machine running amd64 kernel, when run
it reports:
===
# iptables -L
iptables v1.2.11: can't initialize iptables table `filter': Module is
wrong version Perhaps iptables or your kernel needs to be upgraded

iptables has to be 64bit to talk to a 64bit kernel due to an alignment
issue in the kernel structures for iptables.  So you do need at least
the 64bit iptables binary and associated libs.


This time around I am wondering...
> The question is:

   - 32 bit is faster than 64 bit
   - 32 bit is well tested, 64 bit isn't tested at all
   - 2039 is still long way off

The only reasons to compile anything in 64bit architecture:

   - It needs to access more than 4GB of memory. In the real world this
   only applies to huge databases.
   - It needs to talk to the kernel directly. Some applications, like
   iptables, contain ugly hacks to support the 64 bit kernel/32 bit
   userland thing.
   - It is a kernel.

For you to talk with your 64bit kernel, you need 64bit iptables!

Re: Puzzling dead.letter file.

[Lisa Kachold]

This is your security-report, mailed to the the root user from a system
user named "msec"

It will either queue up in root mail or bounce back to the sender  as
dead.letter in the home directory of the sender if your mail is not setup.

*You can configure mail and add an alias to /etc/aliases for root so it
will forward to you to be read?*

http://www.howtoforge.com/perfect-server-mandriva-2010.0-free-x86_64-ispconfig-2(search
forward to the mail section)

Edit /etc/aliases for root (at the bottom) to forward to your email
address) and then enter the command "newaliases"

*To set your security-report settings for mail.*

Run (as root) msecgui.  On the Basic Security tab, there should be an
option called "Send security alerts by email", that you can uncheck.

If the version you have doesn't have that option in the gui, try adding
MAIL_WARN=no
to /etc/security/msec/security.conf or changing the existing value from yes
to no.
BTW you just advertised to the world your listening ports and a user name
(patti),

information as what is related in your security report?

 *You might consider adding the checkrootkit package and run a full scan
now and read those security reports?*

This is possibly a known malloc issue with glibc for your chipset.
Research requires full backtrace, versions, firmware and chipset versions.

The C stack that works fine in some systems can break in others.

Re: Resize partition solution -and- problem.

[Lisa Kachold]

I would try the things in red in my post first.

You don't really want a dual boot box anyway.  Run XP in a Virtualbox?

That means that your connection was refused.

So, you probably have strict checking on in your /etc/ssh/sshd_config and
you named your new system the same as the old one.
You can remove your known_hosts file from ~michael/.ssh/known_hosts file.
You can turn off strict checking also in the /etc/ssh/sshd_config file (not
recommended, even if you ARE on a trusted network).

> The Windows bootloader stores information about how big the partitions on
the hard drive are. If you change a partition size, Windows checks the new
partition size at the very next reboot (using either chkdsk in XP or a new
utility in Vista/Windows 7). It then writes that info to its bootloader
configuration file. If you start mucking around with other partitions
before it has a chance to record the changes and reset itself accordingly,
the Windows bootloader will not be able to read the partition table
properly (and will then refuse to boot entirely).

Since Grub boots Windows merely by chainloading the Windows bootloader, if
the Windows bootloader doesn't work (i.e. doesn't recognize its own changed
partition), then you are sunk.

If you ignore these warnings, I almost guarantee you will fry your Windows
partitioning scheme and be unable to boot up Windows.

It is easiest if your Windows partition is the first one installed. This is
because the Windows bootloader looks for Windows in the first partition.
Also, Windows installers are unpredictable and can overwrite anything that
is already installed on the hard drive.

If you have a brand new computer with no OS pre-installed, partitioning and
OS installation is much easier. Create all your partitions before
installing Windows. Make the first partition NTFS (or the less secure
FAT32, if you wish), intending it for the Windows installation. Then divide
the remainder of the hard drive (using
GParted)
using the partitioning scheme outlined
above.


Generally, a retail "boxed" version of Windows (instead of an OEM or
"backup" copy) installs quite happily to the first pre-configured,
pre-sized partition. Go ahead and install it there, then skip on ahead
to installing
the Linux 
OSs.

 Windows XP (or earlier)

You *can* use 
GPartedto
resize a Windows XP partition directly (without needing
re-installation), but it is still best to reboot Windows XP twice after
resizing its partition (before taking any other steps with GParted).
Review this
tutorial's
section "Making Shrink Volume Work." Although Windows XP does not have a
shrink volume utility, to resize the partition using GParted, these steps
must be taken anyway. Specifically:

   - Use the Disk Cleanup Wizard to remove unnecessary files.
   - Uninstall "dead

http://www.dd-wrt.com/wiki/index.php/Asus_RT-N66U


   - Dual Band Router - 2.4GHz and 5GHz bands
   - Gigabit LAN and WAN switching
   - 2x USB 2.0 connectors
   - CPU Broadcom 4706 @ 600MHz
   - 256MB RAM
   - 32MB FlashRAM


   - Built-in Micro SDHC socket (for up to 8GB Micro SDHC card)
   - Power supply: DC Output, 19 V, max. 1.58 A current


 Also look at this nice new DOCSIS 3.0 cable modem:

http://www.netgear.com/service-provider/products/routers-and-gateways/cable-modems/CMD31T.aspx

Note: When you hook this up, Cox will immediately note that you have a
different MAC address and port forward all port 80/443 to their Call Us
Page.
When you call them, they will get your NEW MAC address and serial number;
whereupon they will send it a signal.  That signal will also implement QoS
or max bandwidth throughput.

You can try to clone your old MAC address on your new device and see if the
signal they send does not limit your throughput, but chances are the max
throughput will not be achieved.

IT WILL however, be well worth the cost of $99.00 and if you want to play
with sbhacker.com images, it can be "modified" with diagnostic firmware
that can include interface bonding, and provide a wide open system with
temporary blocked Cox QoS updates or signal changes.

DISCLAIMER:  Be careful not to BRICK your new devices (available at Fry's
Electronics); follow all instructions and warnings and understand that
stealing Cox cable services will entail consequences.

Re: networking problem

Hi Mike?

Are they on the same subnet?

Is one a wireless and the other a wired?
Does your router allow passthrough to the wired devices on your network?

Re: Connecting to printer connected to another computer.

[Lisa Kachold]

Okay, this looks typical except that you don't have the full networking
part of the driver.

It's recommended that you download and install the Solution:

Completely remove hplip and hplip-data (also completely removed hpijs,
foomatic-db-hpijs and hpijs-ppds),
downloaded hplip-2.8.7.run from hplip.sourceforge.net and ran the automatic
installer.

Note that there are 7 missing "optional" dependencies which it
automatically downloaded & installed; two of these were marked as "REQUIRED
dependency for option 'network'", so attend carefully as you install.

After building, a setup wizard runs which did almost everything by itself
(but for some reason doesn't find the printer by itself -  you will have to
enter its ip address manually), whereupon it will give you a choice of 2
drivers - choose the first one that is listed (not the one called
'recommended').

Printing to this printer now should to work perfectly.

Go into the CUPS "modify printer" process to see what is are now 2 new
items listed in the "device" drop-down menu that were not there before:
HP Fax (HPLIP)
HP Printer (HPLIP)

Also, the device uri that the wizard entered is now:
hp:/net/Photosmart_C7200_series?ip=[my printer's ip address]
and the driver it is using isL
HP Photosmart c7200 series Foomatic/hpijs (en)
I was trying to use "HP PhotoSmart C7200 Foomatic/hpijs (recommended)
(en)". Note that the slight differences in upper/lowercase are not
accidental - compar';

Re: Connecting to printer connected to another computer.

[Lisa Kachold]

Okay, so this is a printer shared through another computer, right?

You can see the printer, but it says it's not plugged in.  What is the
other computer?
Can you see logs from the other computer of access attempts.
What is it whining about?

Re: Connecting to printer connected to another computer.

[Lisa Kachold]

It says "Unplugged or turned off".

That means basically it's "unplugged or turned off".  Check the cabling.

Re: lubuntu 'find'

[Lisa Kachold]

Hi Betty,

To use the mlocate package in Kubutun, you can just enter:

# locate $filepart |more

or for binaries in your $PATH,

# which $filename

Of course if you are not in a su or root session, you will only search your
own $PATH.

If your locate database has not been updated (by cron - setup when the
mlocate package is installed by dpkg) you can also not find things.  You
can manually update this with:

# updatedb &

If you have a huge mounted partition that you don't want to include, you
can configure your /etc/located.conf to ignore that mount or filesystem.

The mlocate package has various Buntu installation bugs, so you might need
to verify it:

# find / -name updatedb

Re: Need Help setting up a VPN Connection to my LAN

[Lisa Kachold]

No, you don't need a license for OpenVPNAS.

http://openvpn.net/index.php/access-server/docs/admin-guides/218-how-to-activate-your-license-in-openvpn-access-server.html

It comes with a couple licenses - if you buy 10 license for use in a
corporate environment, it's $50.00 bill for a lifetime of security.

See *http://openvpn.net/index.php/access-server/license-key.html*

Register and get your free 2 license community license key:

Re: Need Help setting up a VPN Connection to my LAN

[Lisa Kachold]

Hi Mark,

Just so you know, OpenVPN Access Server, automatically sets up all the
databases, certificates and web management.  It's REALLY EASY SOLID and
simple.  You get something like 3 free licenses.

I don't recommend you mess around with the regular OpenVPN instructions
(as linked below on your response) - unless you are masochistic.

Use these:
http://openvpn.net/index.php/access-server/docs/quick-start-guide.html

Excerpt:

*Linux Distribution:*
You will need to make sure you download the package that corresponds with
the current OS Distro, we currently support these Linux Distros:
- Ubuntu
- RHEL
- Fedora
- CentOS
- Debian (Install Ubuntu Packages for Debian)

Click here to download the OpenVPN Access Server
packages<http://openvpn.net/index.php/access-server/download-openvpn-as-sw.html>


*CPU Architecture:
*You will need to make sure you install the correct package depending on
your CPU Architecture (32bit or 64bit)
*
Installing the OpenVPN-AS Package:
*To Install the OpenVPN-AS package in Ubuntu or Debian you will need to run
this command:

*dpkg -i openvpnasdebpack.deb*

To install the OpenVPN-AS package in CentOS, RHEL, or Fedora you will need
to run this command:

*rpm -i openvpnasrpmpack.rpm*

The Admin Account for OpenVPN-AS needs to be setup through terminal by
doing the following:

Change the password:

passwd openvpn

You will then be prompted to set a password for the user openvpn, after
setting the password you can login to the Admin UI with the Username
openvpn and the password you set.

*Note: In some circumstances for certain configurations you may need to run
the complete ovpn-init script terminal: /usr/local/openvpn_as/bin/ovpn-init*

*Configuring the Admin Web Interface:
*After you have completed the Initial Configuration Tool you should then be
able to access the Admin Web Interface through your preferred web browser.
You should have noticed an link to the Admin Web Interface after you
completed the Initial Configuration Tool, if you missed it you can access
the Admin Web Interface by typing the following in your browsers address
bar: https://openvpnasip/admin <https://openvpnasip:943/admin> (Please
replace "openvpnasip" with the IP you allocated to your openvpn-as instance)
<https://openvpnasip:943/admin>
You can now go ahead and login with your openvpn admin credentials. Once
logged in you will see the following screen:

Let's get some background to answer your question as to why Linux makes all
this so complicated:
What distro are you setting up?

Let's go from bottom up:

A) Do you have link light on the card and router?
B) What does the last few entries in "dmesg" show you?
C) What does "tail /var/log/messages" show you [alternately try "tail
/var/log/syslog"]:

Answer back with that info and we can go from there

Some things to "try" if you have network manager:

Remove the /etc/sysconfig/network-scripts/ifcfg-Wired_connection (copy to
backup), and add a new entry in the Gui.
No joy?  simple move it back and enter "service NetworkManager restart"

Check that you don't have iptables enabled (without ports allowed for
67:68):

"iptables-save"
"iptables -F" flushes it (warning if you are using a complex table or
OpenVPN)

Re: Need Help setting up a VPN Connection to my LAN

[Lisa Kachold]

Hi Mark,

The BEFSX41's were not completely configured for anything but SITE<--->SITE
VPN.  An IPSEC tunnel to tunnel can be setup evidently to work with a linux
VPN client. where you have a static client IP address (no NAT), but you are
correct, it's a bit of work.

And there are some known issues:
http://homecommunity.cisco.com/t5/Wired-Routers/VPN-works-causes-periodic-freezes-of-BEFSX41/m-p/227179?comm_cc=HSus&comm_lang=en#226944

Version:
Do you have BEFSX41 v1 or v2?  With the most recent firmware, the VPN page
should look like this:
http://ui.linksys.com/files/BEFSX41/1.52.5/Security-VPN-Tunnel-Enabled.htm

Linksys QuickVPN software and cisco VPN client will not work for IPSEC or
this router.  Linksys has instructions for setting up an IPSEC tunnel for
the BEFSX41 (which is all it supports):
http://homesupport.cisco.com/en-us/wireless/lbc/BEFSX41

As you can see, you can, with this router, do passthrough and OpenVPN is so
nice, easy and powerful, I recommend you just use it (rather than try to
configure VPNs from this router) [simply check all three boxes on the
BEFSX41 and save].

OpenVPN Access Server (OpenVPN-AS) is a set of installation and
configuration tools that simplify the rapid deployment of a VPN remote
access solution. It is based on the popular OpenVPN open-source software,
making the deployed VPN immediately compatible with OpenVPN client software
across multiple user platforms.* *The server configurations options
supported are a carefully selected subset of a quite large set of possible
OpenVPN configurations. Thus, OpenVPN Access Server streamlines the
configuration and management of an OpenVPN-based secure remote access
deployment.
You can get OpenVPNAS here (for Ubuntu, Fedora, CentOs and Redhat, as well
as VirtualMachine images):
http://openvpn.net/index.php/download/access-server-downloads.html

To configure OpenVPN client in Linux:
Simply surf to the port you setup for your OpenVPNAS server [usually
80/443] (be sure to port forward as needed) and login with the user name
and password you setup and it will prompt you to download your client for
Linux, OS X, or Windows.

You are referring to  TLER/ERC/CCTL:

Hard drive manufacturers are drawing a distinction between "desktop" grade
and "enterprise" grade drives. The "desktop" grade drives can take a long
time (~2 minutes) to respond when they find an error, which causes most
RAID systems to label them as failed and drop them from the array. The
solution provided by the manufacturers is for us to purchase the
"enterprise" grade drives, at twice the cost, which report errors promptly
enough so that this isn't a problem. This "enterprise" feature is called
TLER, ERC, and CCTL.

*The Problem:*

There are three problems with this situation:

The first is that it flies in the face of the word *Inexpensive* in the
acronym *Redundant Arrays of Inexpensive Disks
(RAID)*
.

The second is that when a drive starts to fail, you want to know about it,
as Miles Nordin wrote in a long
thread
:
*
Posssible Solutions:*

For a while, Western Digital released a program (WDTLER.EXE) that made it
possible to enable TLER on desktop grade drives. This no longer works.

*Linux:*

This message  implies
that it's impossible to tell a drive to cancel its bad read operation:

You can set the ERC values of your drives. Then they'll stop processing
their internal error recovery procedure after the timeout and continue
to react. Without ERC-timeout, the drive tries to correct the error on
its own (not reacting on any requests), mdraid assumes an error after a
while and tries to rewrite the "missing" sector (assembled from the
other disks). But the drive will still not react to the write request
as it is still doing its internal recovery procedure. Now mdraid
assumes the disk to be bad and kicks it.

There's nothing you can do about this viscious circle except either
enabling ERC or using Raid-Edition disk (which have ERC enabled by default).

Evidence that using ATA ERC commands don't always work:
Both Linux and FreeBSD can use normal desktop drives without TLER, and in
fact you *would not even want TLER* in such a case, since *TLER can be
dangerous* in some circumstances. Read on.


*What is TLER/CCTL/ERC?*
TLER (Time-Limited Error Recovery
CCTL (Command Completion Time Limit)
ERC (Error Recovery Control)

These basically mean the same thing: limit the number of seconds the
harddrive spends on trying to recover a weak or bad sector. TLER and the
other variants are typically configured to 7 seconds, meaning that if the
drive has not managed to recover that sector within 7 seconds, it will give
up and forfeit recovery, and return an I/O error to the host instead.

The behavior without TLER is that up to 120 seconds (20-60 is more
frequent) may pass before a disk gives up recovery. This behavior causes
haywire on all Hardware RAID and Windows-based software/onboard/driver RAIDs.
The RAID consider typically is configured to consider disks that don't
respond in 10 seconds as completely failed; which is bizarre to say the
least! This smells like the vendors have some sort of deal causing you to
buy HDDs at twice the price just for a simple firmware fix. LOL!! Don't get
yourself buttraped; read on!


*When do i need TLER?*
You need TLER-capable disks when using any Hardware RAID or any
Windows-based software RAID; bummer if you're on Windows platform! But this
also means Hardware RAID on any OS (FreeBSD/Linux) would also need TLER
disks; even when configured to run as 'JBOD' array. There may be
controllers with different firmware that allow you to set the timeout limit
for I/O; but i've not yet heard about specific products, except some LSI
1068E in IR mode; but reputable vendors like Areca (FW1.43) certainly
require TLER-enabled disks or they will drop-out like candy whenever you
encounter a bad/weak sector that needs longer recovery than 10 seconds.

Basically, if you use a RAID platform that DEMANDS the disks to respond
within 10 seconds, and will KICK OUT disks that do not respond in time,
then you need TLER.

*When don't I need TLER?*
When using FreeBSD/Linux software RAID on a HBA controller; which is a
RAID-less controller. Areca HW RAID running in JBOD mode is still a RAID
controller; it controls whether the disks are detached, not the OS. With a
true HBA like LSI 1068E (Intel SASUC8i) your OS would have control about
whether to detach the disk or not; and Linux/BSD won't, at le

I like the free offerings, the security sessions and of course Foss Weekly

You have to find your own knowledge, half the learning is in the search?

RHEL ---> Take one of the preparation facttracks (5 days about 3,000 -
