# oslevel -r
# 5300-09

To check what filesets are below the TL you patched to first find all TL levels you have installed :-

# oslevel -r -q
Known Recommended Maintenance Levels
————————————
5300-11
5300-10
5300-09
5300-08
5300-07
5300-06
5300-05
5300-04
5300-03
5300-02
5300-01
5300-00

Next check what filesets are below our highest level e.g. TL11

# oslevel -r -l 5300-11
Fileset                                 Actual Level           Recommended ML
—————————————————————————–
Java5.sdk                               5.0.0.1                5.0.0.235
ifor_ls.html.en_US.base.cli             5.3.7.0                5.3.8.0
#

Here you can see two filesets are at the wrong level. So we need to fix this. Java is a seperate download for AIX you can get it here http://www.ibm.com/developerworks/java/jdk/aix/service.html

Check if you have the 32 or 64 bit version with lslpp -l | grep -i java and download the latest fix – select your highest TL level you have installed when you download. Install using the usual  installp / smiity method.

Re run oslevel -r -l 5300-11
Fileset                                 Actual Level           Recommended ML
—————————————————————————–
ifor_ls.html.en_US.base.cli             5.3.7.0                5.3.8.0

Now only one fileset is below level. A Google shows that there is a bug with the update process for this fileset – simply run the patch process again and it will update to the correct level.

Now oslevel is correct :-

# oslevel -r
5300-11

In /var/log/mesages lots of :-

May 20 09:50:01 Server1 : error getting update info: Cannot retrieve repository metadata (repomd.xml) for repository: epel. Please verify its path and try again

If I run yum -d 9 check-update it hangs at Setting up Package Sacks

Found out that another admin had added epel.repo in /etc/yum.repos.d

As we use a proxy to connect to Redhat it appears there is a feature that if you add repos then you need to update /etc/yum.conf  yum will not pick up the proxy settings from /etc/sysconfig/rhn/up2date

Adding proxy=http://proxy.mydomain.co.uk:8080  to /etc/yum.conf soleved the problem.

I’ve seen CAPTCHA used on other sites as a means to distinguish between humans and Spam bots so a quick Google for Wordpress CAPTCHA plugins found a few. I wanted one that is updated regularly so it will still work when a new Wordpress update is available. The plugin I chose was SI CAPTCHA . This seems to be regularly updated , looks very good, has audio and it works fine – I have had no Spam bot comments since installing. The plugin is free but if you find it useful and want to fund further development then there is a Paypal link – if you think how much time this plugin will save you a donation is highly recommended.

The link on the Wordpress plugins site has all the information needed to install. ( Note for Centos check you have php-gd installed – see below ).  Basically you unzip it into wp-contents/plugins directory then go to your Admin page , select plugins ,  then activate the SI Captcha plugin.

There is a nice Captcha support test link to check all is well – my setup failed first time – I got :-

ERROR: GD image support not detected in PHP

ERROR: imagepng function not detected in PHP

This was resolved by installing php-gd RPM. For Centos you would do

yum install php-gd

service httpd restart

Now if anyone wants to add a comment they have to pass the CAPTCHA test which Spam bots are no good at.

Note by default it won’t add the CAPTCHA box to users who are logged in so ensure you have logged out if you want to test it for yourself.

You should see the CAPTCHA at the bottom of this entry.

If you have an Apache certificate e.g. it was requested with an openssl signing request rather than using ikeyman then you first need to convert it to PKCS12 format which can then be imported into the IBMHTTPServer6 keystore.

openssl pkcs12 -export -out new_key_pair_filename.p12 -inkey private_key_filename.key -in certificate_filename.crt

You will get prompted for a password – you must use the same password as you have on the keystore you want to import it into.

Move the file to /usr/IBMHTTPServer6/bin
If you used strong encryption to generate the signing key request ( and you would have done ) then you may have to install the unrestricted JCE policy files.

To check :-

/usr/IBMHTTPServer6/java/jre/bin/keytool -list -v -keystore /usr/IBMHTTPServer6/bin/wbis104m.p12 -storetype pkcs12 -storepass passwd

If it barfs with java errors like :-

keytool error (likely untranslated): java.io.IOException: Private key decryption error: (java.security.InvalidKeyException: Illegal key size)

keytool error (likely untranslated): java.io.IOException: Private key decryption error: (java.lang.SecurityException: Unsupported keysize or algorithm parameter
s)

You need to install the unrestricted JCE policy files.

Download the zip file from https://www14.software.ibm.com/webapp/iwm/web/preLogin.do?source=jcesdk ( you need an IBM ID – this is a free registration )

unzip and after making copies of the orginals copy over the new local_policy.jar US_export_policy.jar files to /usr/IBMHTTPServer6/java/jre/lib/security

Rerun the keytool command above ( ensuring you use the full path to the keytool command ) to confirm it lists the certificate details without Java errors.

Now add it into the keystore

You need to be able to use X as the ikeyman program is GUI only.

su to root , export XAUTHORITY and DISPLAY to those of the user you su’d from.

e.g.

export XAUTHORITY=/home/fred/.Xauthority

export DISPLAY=localhost:10.0

cd /usr/IBMHTTPServer6/bin

./ikeyman

Key Database File – Open

Key Database type CMS

Location /usr/IBMHTTPServer6/keys/

File Name key.kdb

You will be prompted for the password

Now import the certificate you converted to pkcs12 format above

Ensure Personal Certificates is selected then click on Export/Import

Select Import Key

Key file type PKCS12

File Name the file name of the converted pkcs12 format above

Location where you put the file

Click OK – you will be prompted for a password – use the one you set when you did the conversion ( which should also be the same as the keystore password you are putting it in )

If you get a message “The specified database has been corrupted” ensure you have installed the unrestricted JCE policy files above. If you have to install them you need to exit ikeyman and restart it again.

You should now get a dialog asking if you would like to change any of these labels before completeing the import process

Click on the label ( which is probably a very long string ) and then change it to something like prod-cert ( this is the name you will use in the httpd.conf file )

Click apply

Click OK ( you may have to scroll to the right to see the OK button )

If you now get an error An attempt to import the certificate has failed.

All the signer certificates must exist in the key database

This probably means that you need to install the Verisign intermediate signers certificate.

https://knowledge.verisign.com/support/ssl-certificates-support/index?page=content&id=AR657

Assuming it is a standard Verisign site certifiacate ( class 3 ) then go here :-

http://www.verisign.com/support/verisign-intermediate-ca/secure-site-intermediate/index.html

Cut and paste the certificate into a file and save with a .arm extension

Go into ikeyman and open the keystore as above

Select Signer Certificates

Click add

Data type Base64-encoded ASCII data

Certificate file name the name of the arm file you created above

Location the location of the arm file

Click OK

Enter a label for the certificate – choose something like Verisign intermediate CA cert

Click OK

Now select Personal Certificates and import the converted PKCS12 SSL certificate using the intructions as before.

Adding the certificate to the httpd.conf file

vi /usr/IBMHTTPServer6/conf/httpd.conf

search for SSLServerCert and change the name of the certificate to the name you chose when you added the certificate to the key store e.g. prod-cert

Restart apache

I checked my router for DHCP clients to confirm the Squeebox Duet and controller were connected and I was surprised to see a DHCP connection from my newly upgraded Ubuntu server as it should have been a static IP. I seem to remember I had the same problem last time I upgraded – anyway as the Squeezebox expects to see the Ubuntu server running the  music library daemon on a static IP I assumed this was the problem.

Reverting back to a static IP address after upgrading Ubuntu

From the tool bar – System – Preferences – Network Connections

Select  Wired connection 1 – Edit

Check the IPV4 Settings tab for the correct IP address then click apply.

Open up a terminal and restart the network

sudo /etc/init.d/networking restart

Check with ifconfig -a that the required static IP address has been applied.

Squeezebox stil not finding my music library

Now I had the right IP address on my Ubuntu server the Squeezebox still would not find the music library.

I checked on the Ubuntu server if the squeecenter daemon was running ( ps -ef | grep squee ) – it was not. I attempted to restart it :-

sudo /etc/init.d/squeezecenter restart
Restarting squeezecenterNo squeezecenter_s found running; none killed.
start-stop-daemon: stat /usr/sbin/squeezecenter_safe: No such file or directory (No such file or directory)

Oh dear – time for a Google search. Apparently the 9.10 upgrade to MySql broke it and I needed to download the latest ( beta ) version 7.4.2 of squeeboxserver ( the new name for squeezecenter ). You can get it from

http://downloads.slimdevices.com/nightly/?ver=7.4

In Ubuntu if you click on the Debian installer package link then an installer will start up – ask you confirm you want it installed and warn about an older version available in the repository which would be more stable. After installer I started it up :-

sudo /etc/init.d/squeezeboxserver start

As I was using squeezecenter rather than squeezeboxserver I had to configure it to tell it where my music files and play list were. To do this connect to http://localhost:9000 , type in your squuebox network login ( or register if you don’t have one ) and then follow the instructions to point to your music and playlist files.

I did not have enough free space in the OS partition but had lots on another partition.

Ubuntu downloads new versions of programs to a cache area :-  /var/cache/apt/archives

All you need to do is to move this to another filesystem with enough free space and then link to it.

cd /var/cache/apt

sudo mv archives  /newfilesytem

sudo ln -s /newfilesystem/archives

Now your Ubuntu upgrade should have enough free space

First convert the number of days to hours e.g. if you want to find the date 90 days ago you need 90 * 24 = 2160

echo `TZ=GMT+2160 date +%d/%m/%y`

You can of course use any of the % formats to get the output you require.

To compare two dates ( very useful in AIX to see if a user has not logged in for 90 days for example ) use the %s to get the number of seconds since 1st Jan 1970 :-

echo `TZ=GMT+2160 date +%s`

lsuser  -a time_last_login username   ( needs to run as root )

Then compare the two numbers and if the 90 days ago number is gretaer than the output of the lsuer command then that user has not logged in for gretaer than 90 days

I wanted to have my own weather station and output the weather on a web page on my VPS server. There are plenty of weather stations available that will output data to a PC and several applications that will display that data on a web page. Most weather stations come with software but it is Windoze based and not Linux. Looking around for weather display software that will run on Linux I found Weather Display this supports a large range of stations , has lots of nice features , runs on Linux ( as well as Mac OSX and Windoze ) but costs around $70.

Looking for free software I found open2300 , this will get data from a La crosse WS2300/WS2305/WS2310/WS2315 Weather Station as well as sending data to Weather Underground and Citizen Weather. There are some very nice web sites using this software as a base for some extra coding. It will also run on a Linksys NSLU2.

Next I found wview , this supports a number of weather stations :-

This produces a nice web page as on my server. The software will also run on a Linksys NSLU2 which has been modified to run a full version of Linux which means I don’t have to leave my main PC on all the time to collect the data. I happen to have a NSLU2 which I modifed to run a full version of Linux which I was using as a media streamer ( Firefly ) to stream audio to a Roku Soundbridge and as a backup server  – I have now bought a SqueezeBox Duet and the NSLU2 is a bit too weedy for the SqueezeCenter software so I decided to run wview on this and send the generated HTML over to my VPS server on the net.

Weather Station choice

Having decided on wview the supported weather stations currently available in the UK are  the La Crosse WS2300 series and the Davis Vantage Pro, as the Davis Vantage Pro with a PC cable is around four times the price of the La Crosse I decided to buy a La Crosse WS2308. This weather station will also work with the open2300 and WeatherDisplay software mentioned above. It measures indoor/outdoor temperature and humidity ,dew point, wind chill, wind speed and direction, atmospheric pressure and has a rain gauge to measure rain fall. It has a large LCD display unit that can either receive the data from the instruments via cable or wireless – I chose the wireless option as It is the most convenient although it can be less reliable and if you do lose contact with the sensors the PC output will show the outside temperature as 80 degrees C which buggers up your graphs !

The outside instruments are housed in three units connected together by cable. I mounted the wind anemometer on a TV aerial mast and the rain gauge on a simple L bracket. See the picture below. The TV mast and the bracket to mount it on the wall came from Maplin Electronics.

WS2308 weather station instruments

Prepare the NSLU2 for the Wview software

As noted above I wanted to install wview on my Linksys NSLU2, the version of Linux I had on there was too old to install wview and so I had to install a new version. To do this the instructions are on the NSLU2 Wiki site. Initially I installed the latest SlugOS ( 5.3 Beta ) but the wview packages ( I decided against compiling the latest version from source as I wanted to get something up and running quickly )  had dependency problems so I installed SlugOS 4.8 Beta as suggested in the manual. As I already had a version of Linux on the NSLU2 ( Unslung ) it was easy to do and it even kept all my data on the USB disk attached. I used sudo upslug2 –image=”slugosbe-4.8-beta-nslu2.bin” from by Ubuntu desktop to flash the new image onto the NSLU2 and once rebooted df showed :-

root@nslug:~$ df

and fdisk /dev/sda :-

/dev/sda3           30395       30401       56227+ 82 Linux swap

/media/sda2 was the Unslung root partition so I made it the SlugOS one :-
root@nslug:~$  umount /media/sda2
root@nslug:~$ mkfs.ext3 /dev/sda2
root@nslug:~$ turnup disk -i /dev/sda2 -t ext3

Rebooted the NSLU2

I already had swap on sda3 but it was the wrong version so I remade it :-

root@nslug:~# mkswap /dev/sda3
Setting up swapspace version 1, size = 57572864 bytes
vi /etc/fstab
/dev/sda3       swap    swap    defaults        0       0
root@nslug:~# swapon -a

The NSLU2 does not have an accessible serial port to connect to the weather station. To use a serial connection to the NSLU2 see the Linux NSLU2 Wiki page here.

I choose the easy option to use a serial to USB converter cable ( from Maplin Electronics code ZP43 ).

Look for your weather station model – in my case ws2300 :-

wview-ws2300-mysql – 4.0.1-r0 – wview is a weather site generator and more for a variety of weather stations

root@nslug:/etc/ipkg$ ipkg install wview-ws2300-mysql
Installing wview-ws2300-mysql (4.0.1-r0) to root…
downloads lots of dependent libraries etc.

Make the archive directory go to disk rather than in /var ( which is memory on the NSLU2 )

root@nslug:~$ mkdir /media/sda1/wview
root@nslug:~$ mkdir /media/sda1/wview/archive
root@nslug:~$ rmdir /var/wview/archive
root@nslug:~$ ln -s /media/sda1/wview/archive /var/wview/archive
root@nslug:~$

Next run the setup script wviewconfig. In most cases I accepted the defaults except as below

wviewconfig

Serial port device – check with dmesg what in is – in my case it is /dev/ttyUSB0

Use metric measures
Weather station elevation (feet above sea level ) you can get this information from various sites on the Internet – I used http://www.earthtools.org/

This site will also give you latitude and longitude

Local Radar use Google to find a site that you can link to for a radar display or look at other weather sites to see what other people have used.

Ditto for local forcast

Run the rsync/ssh daemon wviewsshd?
1
As I wanted to use my VPS server on the Internet I use the wviewsshd daemon which does rsync over ssh to get the data to the external server – more about this below.

After wviewconfig has finished run the script wviewhtmlconfig – I accepted defaults.

You can always change settings getnerated by the above two scripts at a later date by editing /etc/wview/wview.conf or /etc/wview/htmlgen.conf and restarting wview.

Setting up rsync to send the data to an external web server

On the NSLU2

root@nslug:/etc/ipkg$ ipkg install rsync

ssh-keygen -t rsa           don’t set a passphrase and accept the defaults

cat /root/id_rsa.pub

On your external server

-bash-3.2# useradd -m -d /home/wview -c “Wview weather” wview
-bash-3.2# cd ~wview
-bash-3.2# mkdir .ssh
-bash-3.2# vi .ssh/authorized_keys

paste in the output of the cat /root/id_rsa.pub command you ran on the NSLU2 above

-bash-3.2# chown -R wview:wview /home/wview/.ssh
-bash-3.2# chmod 700 /home/wview/.ssh
-bash-3.2# mkdir /var/www/html/weather         (replace /var/www/html with your web server’s document root )

-bash-3.2# chown wview:wview /var/www/html/weather

-bash-3.2# ln -s /var/www/html/weather data

If rsync is not installed then install it :-

yum install rsync

On the NSLU2

Test the ssh connection :-

root@nslug:-$ ssh -l wview yourextserver.org ls -l /home

Answer yes to the question about if you want to connect and you should get a listing of the external server’s /home without being prompted for a password.

root@nslug:-$ vi /root/.ssh/config

Host yourextserver.org

User wview

This means that root will always ssh as user wview when going to your external server.

Test rsync

root@nslug:-$ rsync -aqz –rsh=ssh /var/wview/img/ tuqix.org:data
root@nslug:-$  ssh yourextserver.org ls -l data

root@nslug:-$  vi /etc/wview/wviewssh.conf
#Interval Source                        Remote Host               Remote Destination
#——– —————————–  ————————-         ————–
1         /var/wview/img                yourextserver.org                                 data

Plug in the weather station LCD control panel to the serial to USB cable using the serial cable that comes with the weather station.

Start up wview and monitor the mesages file:-

root@nslug:-$ /etc/init.d/wview start

root@nslug:-$ tail -f /var/log/messages

You should see messages like :-
