1 liter ljummet vatten (ca 37grader slås på en burk (el kartong) farin och 1 hg margarin.
När allt löst sig tillsätter man 1 tsk salt, 2 pkt jäst,1 kg vete, 1 kg rågsikt, några teskedar krossade brödkryddor ( anis och fänkål)
Allt arbetas ihop, helst i en assistent, till en smidig deg, som släpper bunken.
Degen delas i 6 delar och formas till limpor, ”levar” två stycken på varje plåt, som är täckt med bakplåts-papper (ej smörgåspapper)
Lägg bakhandukar över limporna och låt allt jäsa på dragfri plats i 2 timmar.
Värm under tiden upp ugnen till 175 gr. Sätt in första plåten utan bakdukar på nedre falsen tills ”leven”, limpan alltså, fått fin färg. Detta tar nog ½ timme eller mer,
Pensla sedan limporna med hett, kokande vatten, så blir de blanka och den yttre sötman, kommer fram tydligare
Linda in de färdiga levarna i handukar, så de får kallna.
Dela limporna på mitten och frys in i fryspåse!

Create bootable USB stick from ISO in Mac OS X
Convert the ISO to UDRW format
$ hdiutil convert -format UDRW -o destination_file.img source_file.iso
Prepare the USB stick
$ diskutil list
$ diskutil partitionDisk /dev/disk4 1 "Free Space" "unused" "100%"
Copy the image to the USB stick
$ dd if=destination_file.img.dmg of=/dev/rdisk4 bs=1m
$ diskutil eject /dev/disk4
Openssl, convert
Convert a DER file (.crt .cer .der) to PEM
openssl x509 -inform der -in certificate.cer -out certificate.pem
Convert a PEM file to DER
openssl x509 -outform der -in certificate.pem -out certificate.der
Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM
openssl pkcs12 -in keyStore.pfx -out keyStore.pem -nodes
You can add -nocerts to only output the private key or add -nokeys to only output the certificates.
Convert a PEM certificate file and a private key to PKCS#12 (.pfx .p12)
openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key \ -in certificate.crt -certfile CACert.crt

Unzip cnmonitor-3.2.1-1.zip in /usr/share
$ sudo unzip cnmonitor-3.2.1-1.zip -d /usr/share
Install database schema
$ mysql -u root -p < /usr/share/cnmonitor/sql/mysql.sql
Restart Apache Web server
$ sudo service apache2 restart
Move config directory to /etc, create symbolic link and set file permissions:
$ sudo mv /usr/share/cnmonitor/config /etc/cnmonitor $ sudo ln -s /etc/cnmonitor /usr/share/cnmonitor/config $ sudo chown -R root:www-data /etc/cnmonitor $ sudo chmod -R 650 /etc/cnmonitor $ sudo chmod -R +x /usr/share/cnmonitor/bin
Copy cnmonitor.conf to conf-available directory
$ sudo cp /usr/share/cnmonitor/conf/httpd/cnmonitor.conf /etc/apache2/conf-available/.
Enable cnmonitor configuration in Apache Web server
$ sudo a2enconf cnmonitor
Activate the new configuration
$ sudo service apache2 reload
Configure cn=monitor
Please refer to section ”5. Configuration” in CN=Monitor 3.2.1.pdf
