How Priority Inbox works
In order to predict which messages are important to you, Gmail uses some of the same technology that it uses to weed spam out of your Inbox. If it incorrectly predicts which messages are important you can help train it with the importance buttons just like you can help Gmail’s spam filter by using the Report as spam button.

Automatically determining importance
To predict which of your incoming messages are important, Gmail automatically takes into account a number of signals, including:
Who sent the email (For example, if you email Bob a lot, it’s likely that messages from Bob are important.)
What terms it includes (If you always read messages about soccer, a new message that contains those same soccer words is more likely to be important.)
The actions that help us determine which people/terms are important to you include: replying, using stars, archiving, deleting (Messages you star are probably more important than messages you archive without opening.)
This is all done automatically, and no humans ever read your mail.

Training
Email importance ranking works best for people who receive a lot of email. If you don’t receive tens or hundreds of messages a day (or even if you do!), you can help train Gmail to classify your important messages more accurately using the important and not important buttons. If a certain type of message isn’t getting classified correctly, use the buttons or create a filter.
Using the ‘important’ and ‘not important’ buttons:
Select the misclassified message, and click the “mark as important” or “mark as not important” button. When you mark a message, it will move to the appropriate section. This will help Priority Inbox learn what you care about most.

So, to workaround this 1000 user limit issue we had to change the number of records that Active Directory places in 1 page. Active Directory by default will place 1000 users on one page, then any additional users on the next page and so on… Workgroup Manager does not understand this paging system very well so it only displays the first page.

What you will need to do is go on to your AD server and run the ntdsutil util. Here are the steps

To start Ntdsutil.exe

Click Start, and then click Run.In the Open text box, type ntdsutil, and then press ENTER. To view Help at any time, type ? at the command prompt.
To view policy settings

At the Ntdsutil.exe command prompt, type LDAP policies, and then press ENTER.

At the LDAP policy command prompt, type connections, and then press ENTER.

At the server connection command prompt, type connect to server , and then press ENTER. Connect to the server that you are currently working with.

At the server connection command prompt, type q, and then press ENTER to return to the previous menu.

At the LDAP policy command prompt, type Show Values, and then press ENTER.

To change policy settings

At the Ntdsutil.exe command prompt, type LDAP policies, and then press ENTER.At the LDAP policy command prompt, type Set MaxPageSize to 2000, and then press ENTER.

You can use the Show Values command to verify your changes.

To save the changes, use Commit Changes.

When you finish, type q, and then press ENTER.

To quit Ntdsutil.exe, at the command prompt, type q, and then press ENTER.

It basically does the same thing an echo does, but this small step has allowed us to learn a whole lot more about the inner workings of the hip-hop beast and will hopefully have a for loop going soon-ish.

So far it has been a week since the project kicked off and we have made some interesting discoveries about how TBB (Thread Building Blocks) and Hip-Hop works.

Currently we have made progress in the following areas:

Hip-Hop:
- made Hip-Hop compile and work on a 32-bit machine
- figured out how the functions are defined such as the for statement and echo
- passed in a php file to get c++ code at the end

TBB:
- Made first Parallel program today
- Learnt a bit more about how the parallel_for fucntion works

I will try and keep posting our progress on this blog every Friday(NZST)

Wish us Luck!

Carlton’s Online Notebook

The commands and things used in this guide are explained in more details on those sites. If you want to know what the commands are for then please feel free to visit those sites.

Here is the guide:

Install postfix and remove sendmail

yum install postfix
yum remove sendmail

Check to see if postfix has been compiled with the necessary files

ldd `which postfix` | grep libsasl
ldd `which postfix` | grep libssl

They should hopefully return something like this:
# ldd `which postfix` | grep libsasl
libsasl2.so.2 => /usr/lib64/libsasl2.so.2 (0x00007f646039a000)

# ldd `which postfix` | grep libssl
libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007f0ed4b79000)

This should work for a base install of Fedora 12, if you do not see any outputs then you might need a different version of postfix.

Next we need to make sure that openssl and openssl-perl are both installed and up to date. These will be used to generate ssl certificates

yum install openssl openssl-perl

We need to make ourselves a Certificate Authority..You can skip this step if you already have certificated made

Peform these actions as root (su):

mkdir -m 0755 /etc/pki_jungle

mkdir -m 0755 \
/etc/pki_jungle/myCA \
/etc/pki_jungle/myCA/private \
/etc/pki_jungle/myCA/certs \
/etc/pki_jungle/myCA/newcerts \
/etc/pki_jungle/myCA/crlcp /etc/pki/tls/openssl.cnf /etc/pki_jungle/myCA/openssl.my.cnf

openssl req -config openssl.my.cnf -new -x509 -extensions v3_ca -keyout private/myca.key -out certs/myca.crt -days 1825

At this point you will be prompted for a passphrase, choose a strong passphrase

Country Name (2 letter code) [NZ]:ER
State or Province Name (full name) [Earth]:Earth
Locality Name (eg, city) []: Land
Organization Name (eg, company) [My Company Ltd]:My Network
Organizational Unit Name (eg, section) []:My Certificate Authority
Common Name (eg, your name or your server’s hostname) []:server.example.com
Email Address []:whatever@server.example.com

once that is done

chmod 0400 /etc/pki_jungle/myCA/private/myca.key

Next we need to edit the openssl.my.cnf, I would recommend using something like WinSCP if you are not comfortable with commandline text editors

Open /etc/pki_jungle/myCA/openssl.my.cnf and make the following changes

[ CA_default ]dir = . # <--CHANGE THIS
certs = $dir/certs
crl_dir = $dir/crl
database = $dir/index.txt
#unique_subject = no

cd /etc/pki_jungle/myCA/

openssl req -config openssl.my.cnf -new -nodes -keyout private/server.key -out server.csr -days 365

Fill out the fields as previously done

Country Name (2 letter code) [NZ]:ER
State or Province Name (full name) [Earth]:Earth
Locality Name (eg, city) []: Land
Organization Name (eg, company) [My Company Ltd]:My Network
Organizational Unit Name (eg, section) []:My Certificate Authority
Common Name (eg, your name or your server’s hostname) []:server.example.com
Email Address []:whatever@server.example.com

The Common Name (CN) is the info that uniquely distinguishes your service, so be sure that you type it correctly.
When prompted for some extra attributes (challenge password, optional company name) just hit the [Enter] key.

chown root.root /etc/pki_jungle/myCA/private/server.key
chmod 0400 /etc/pki_jungle/myCA/private/server.key

cd /etc/pki_jungle/myCA/

openssl ca -config openssl.my.cnf -policy policy_anything -out certs/server.crt -infiles server.csr

Download the Thawte certs from here https://www.thawte.com/roots/index.html

Unzip the file and copy the Thawte Roots\Thawte Personal Root Certificates\Thawte Personal Premium CA\Thawte Personal Premium CA.pem to /etc/pki_jungle/myCA/certs/ make sure to remove all the spaces from the filename

You will need to create a file called sasl_passwd in the /etc/postfix directory

Add the following to the sasl_passwd:

[smtp.gmail.com]:587 user@gmail.com:password

After the file is created run the following command

postmap /etc/postfix/sasl_passwd

chown root.postfix /etc/postfix/sasl_passwd*

chmod 0640 /etc/postfix/sasl_passwd*

Next edit /etc/postfix/main.cf and add the following to the bottom of the file

#### GMail SSL SMTP Relay
relayhost = [smtp.gmail.com]:587

#auth
smtp_sasl_auth_enable=yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

#tls
smtp_use_tls = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
smtp_tls_note_starttls_offer = yes
tls_random_source = dev:/dev/urandom
smtp_tls_scert_verifydepth = 5
smtp_tls_key_file=/etc/pki_jungle/myCA/private/server.key
smtp_tls_cert_file=/etc/pki_jungle/myCA/certs/server.crt
smtpd_tls_ask_ccert = yes
smtpd_tls_req_ccert =no
smtp_tls_enforce_peername = no
smtpd_use_tls = yes
smtpd_tls_auth_only = no
smtp_tls_CAfile = /etc/pki_jungle/myCA/certs/ThawtePersonalPremiumCA.pem


While you have main.cf open you might want to change a few other things aswell. Uncomment by removing the # character and fill in the settings which suit your network

myhostname = smtp.nav.local
mydomain = nav.local
myorigin = $mydomain
inet_interfaces = all
(comment out inet_interfaces = localhost so it reads #inet_interfaces = localhost)

Save the file

On your fedora box go to System > Administration > Firewall

Tick the Mail (SMTP) box and click on apply.

Next restart your postfix service by typing in

/etc/init.d/postfix restart

You should now be able to configure your mail client to use your server as an smtp server. If you cannot send mail out then have a look at /var/log/maillogs for some information.

Firstly, what you need to do is figure out where the updates are being downloaded from. In this example I will be adding Avira Free edition to the update caching list. In my case Avira gets all its updates from http://dl[0-9].avgate.net. If you are unsure of where your updates are being downloaded from URL Helper is a great utility to use, as this will also tell you which extensions are being downloaded which will be usefull later on.

Once you have figured out where the updates are coming from, the editing can begin. For all my editing I used the portable version of WinSCP, remeber to enable ssh first on your ip cop box by going System > SSH Access > Tick SSH Access and click save. Next fire up WinSCP and fill in the details related to your installation of IPCOP. Remeber to use port 222 instead of 22.

Next you want to browse to /usr/sbin/updxlrator and edit it. By default WinSCP opens up the root directory so you may have to click the .. at the top to get to the previous directory level. Right click on the file and click edit. This should open up WinSCP‘s default editor.
Find the Section of the file which says something like:
# -----------------------------------------------------------
# Section: Windows Update / Windows Downloads
# -----------------------------------------------------------

This is where you custom code will go, In my case I just copied the Avast coding and changed it to where Avira gets its updates.

To do that copy the Avast coding ..
# -----------------------------------------------------------
# Section: Avast Downloads
# -----------------------------------------------------------if ($source_url =~ m@^http://download[\d]+\.avast\.com/.*\.(exe|vpu)$@i)
{
$xlrator_url = &check_cache($source_url,$hostaddr,$username,"Avast",$mirror);
}# -----------------------------------------------------------

and paste it just above the # ———————————————————– line. In my case with Avira I needed to change the source url line of $source_url =~ m@^http://download[\d]+\.avast\.com/.*\.(exe|vpu)$@i to look something like $source_url =~ m@^http://dl[0-9]\.avgate\.net/.*\.(exe|dll|vdf|dat|gz)$@i the rest of the coding remains unchanged. You may want to change the vendor ID to “Other” though otherwise you will need to do a few more edits to get everything working correctly.

So my finished section looks like this (no custom vendor logo):

# -----------------------------------------------------------
# Section: Avast Downloads
# -----------------------------------------------------------if ($source_url =~ m@^http://download[\d]+\.avast\.com/.*\.(exe|vpu)$@i)
{
$xlrator_url = &check_cache($source_url,$hostaddr,$username,"Avast",$mirror);
}# -----------------------------------------------------------
# -----------------------------------------------------------
# Section: Avira Downloads
# -----------------------------------------------------------

If you don’t want custom logo for the updates you are trying to cache then you are pretty much done at this point, if you would like to add custom logo and vendor ID then continue reading.

Change “Other” to “Avira” save and close the file. Next you will need to open up /home/httpd/cgi-bin/updatexlrator.cgi and perform the following edits:

Find:
elsif ($vendorid =~ /^Microsoft$/i)
{
print "<img src='/images/updxl-src-windows.gif' alt='Microsoft'}' />&nbsp;</td>\n";
}

After Add:
elsif ($vendorid =~ /^Avira$/i)
{
print "<img src='/images/updxl-src-avira.gif' alt='Avira'}' />&nbsp;</td>\n";
}

Final Result:
elsif ($vendorid =~ /^Microsoft$/i)
{
print "<img src='/images/updxl-src-windows.gif' alt='Microsoft'}' />&nbsp;</td>\n";
}elsif ($vendorid =~ /^Avira$/i)
{
print "<img src='/images/updxl-src-avira.gif' alt='Avira'}' />&nbsp;</td>\n";
}

Next Find:
elsif ($vendorid =~ /^Microsoft$/i)
{
print "<img src='/images/updxl-src-windows.gif' alt='Microsoft'}' />&nbsp;</nobr></td>\n";
print "<td class='base'>&nbsp;Microsoft&nbsp;</td>\n";
}

After Add:
elsif ($vendorid =~ /^Avira$/i)
{
print "<img src='/images/updxl-src-avira.gif' alt='Avira'}' />&nbsp;</nobr></td>\n";
print "<td class='base'>&nbsp;Avira Antivirus&nbsp;</td>\n";
}

Find:
elsif ($vendorid =~ /^Microsoft$/i)
{
print "<img src='/images/updxl-src-windows.gif' alt='Microsoft'}' />&nbsp;</td>\n";
}
Add After:
elsif ($vendorid =~ /^Avira$/i)
{
print "<img src='/images/updxl-src-avira.gif' alt='Avira'}' />&nbsp;</td>\n";
}
Find:
<td align='center'><img src='/images/updxl-src-symantec.gif' alt='Symantec' /></td>
<td class='base'>Symantec</td>
<td class='base'>&nbsp;</td>
Add After:
<td align='center'><img src='/images/updxl-src-avira.gif' alt='Avira' /></td>
<td class='base'>Avira Antivirus</td>
<td class='base'>&nbsp;</td>

Next make a 18×18 gif image and call it updxl-src-avira.gif or whichever program it is. Once you have the image place it in /home/httpd/html/images

That should be it, your custom software updates will now be cached.

Once in the regedit utility I browsed to the following reg key:

HKEY_LOCAL_MACHINE\SYSTEM_on_C\ControlSet001\Control\CrashControl

and changed the AutoReboot Value from 1 to 0

Note: System_on_C will show up only if you are using the UBCD4Win regedit, to do this without UBCD4Win microsoft had a pretty good writeup about it on their support site.

Once I rebooted I could see what the BSOD was saying and it turned out to be the good ‘ol PAGE_FAULT_IN_NONPAGED_AREA issue. This kind of error usually occurs when there is a memory fault, but I recently read on computerworld that one of the microsoft updates(KB977165) caused random BSODS.

So, to remove this update I booted into UBCD4Win again and did the following:

Open Command Prompt

go to C:\WINDOWS

So at this point the command window should read something like C:\WINDOWS>

then CD $NtUninstallKB977165$\spuninst

once in the spuninst directory run the uninstall txt file as a script by typing BATCH spuninst.txt

In my case this did not work.. so I just renamed the spuninst.txt to spuninst.bat by running “ren spuninst.txt spuninst.bat”

After running the batch file rebooted into windows and everything was fine.

So, to get around this, there is a handy keyboard shortcut you can use. Select the window that not on the monitor and press win + shift + left to move it to a monitor on the left if you press the right arrow key it will move it to the right.

Problem 1:

If a terminal Service session times out, it is unable to reconnect to the server and a blank screen remains.

Solution:

There is a file called .rdesktop which gets created in the root directory. This file prevents a connection from being made again. So the solution was to just remove this file whenever a connection is being made. To do this perform the following edits:

If you have already installed PCTSC to the harddrive then the file will be located at /usr/local/bin, browse to that location and edit the pctsc.auto.tsc file with you favorite text editor. Add the following line rm -rf ~/.rdesktop above the rdesktop -f -k en-us -N -K -u “” -a 24 `cat /etc/pctsc.target` line.

If you have not installed PCTSC then you need to look in the TSC folder located in root. Browse to TSC then usr.local.bin to find the pctsc.auto.tsc file. Apply the same changes as mentioned above.

Problem 2

If the power goes out or a user turns the pc off at the wall then Puppy Linux will not boot up into X. This is a major problem as end users will not know what to do..

Solution

I had to actually switch versions of puppy linux for this to work, I was using Puppy version 4.3.1 but this was no good as the fix i found browsing the puppy forums did not work on this version ( although it did seem to work for certain hardware.. not sure what’s up with that.)

So I downloaded Puppy version puppy-4.2-k2.6.25.16-seamonkey and applyed the following fixes.

Open up /etc/rc.d/rc.sysinit and add the following lines:

Find:

ln -s /proc/mounts /etc/mtab

After that line add:

#————————————————————————————————-
##############SHUTDOWN RECOVERY Add to /etc/rc.d/rc.sysinit################
#If we were not shutdown cleanly, try and recover
if [ -f /RUNNING ];then
echo -n “(Cleaning up after Unclean SHUTDOWN)” >/dev/console
rm -f /var/log/X*
rm -f /RUNNING
rm -rf /tmp/*
rm -f /var/lock/LCK*
rm -f /var/run/*.pid
rm -rf /root/tmp 2>/dev/null
rm -rf /root/.thumbnails/* 2>/dev/null
rm -f /etc/.XLOADED
fi

###################Detect Bad Shut######################
#create a file in tmp that should be deleted on a clean shutdown
if [ ! -f /RUNNING ];then
echo ‘this file is deleted during a clean shutdown’ > /RUNNING
fi
#————————————————————————————————-

Open up /etc/rc.d/rc.shutdown

Find:

echo “Puppy is now shutting down…” > /dev/console

After it add:

#————————————————————
rm -f /RUNNING
echo “Puppy is deleting RUNNING…” > /dev/console
#————————————————————

Those are all the edits I had to do and Puppy is running all good now without any problems.
