Linux CentOS 7 PHP mail() function SMTP Settings

Had some changes in email setup and security levels. Since setting up OAuth2.0 is a little tricky decided to set up a separate Gmail account for sending mail from this server. 

Took my an hour to figure out how this was set up on this machine so this time decided to write it down here.

The PHP script uses "mail($email_address,$subject,$body, $header)", on our system this meant that means it uses the Linux mail binary. The SMTP settings for this are located here: /etc/mail/authinfo/casmtp-auth

I changed the one line in this file with this syntax:

AuthInfo: "U:root" "I:email@address.com" "P:password"

That was not all, next was:

makemap -r hash smtp-auth.db < smtp-auth

Then:

systemctl restart sendmail

Fixing MacOS Time Machine Restore

Had a Macbook Pro 2014 model acting up and finally no longer booting. Booting the Mac in recovery mode but could not even run any first aid on the SSD. Took out the SSD and put it in an external thunderbolt enclosure, same problem.

Ordered a new SSD and installed it in the machine. Tried to recover the machine using Time Machine backups that were kept on a local Qnap NAS. Whatever I tried I could net see any backups. I could see the server and was asked for username/password to access the backups. When pressing ok I simply returned to the first screen, no error nothing, but also no backups.

After many hours of messing around and trying stuff with the server and with other Macs I noticed something. Two Macs, both 10.15 Catalina created a directory (sparsebundle) on the Qnap with: "<machinename>.backupbundle". I had a Mac Mini with MacOS 11 Big Sur and in all the testing had this starting to make backups to the same Qnap. Here I noticed that this created a directory called  "<machinename>.sparsebundle". I noticed that the file-setup and directory structure inside both directories looked the same.

Then I did a new test by connecting the Macbook Pro in Recovery Mode to the Qnap again, and since now in the meantime the Mac Mini was creating a backup there (with the .sparsebundle name) This suddenly showed up as an option to recover from. 

After spending so much time debugging this problem I accessed the Qnap via SSH and simply renamed MacBookPro.backupbundle to MacBookPro.sparsebundle and now this was also available as a restore point! 

TL;DR: If you can't see any Time Machine backups on a NAS try renaming the directory from X.backupbundle to X.sparsebundle. But use with caution and make sure to have a backup of your backup first!!

Getting OpenVPN OVPN File from CentOS7 Server

We already have OpenVPN running on our CentOS 7 server. To set up a new client on a remote QNAP I wanted to get a better way of getting the client config files from the server

yum -y install https://as-repository.openvpn.net/as-repo-centos7.rpm
yum -y install openvpn-as 

Set a new password for openvpn user:
passwd openvpn

Access the web interface using to download a client file (I downloaded the Linux file):
https://a.b.c.d:943/

Use https://a.b.c.d:943/admin for administration


In the QNAP I loaded the OpenVPN by adding the profile and typing in the username password

Backing up QNAP Server with CentOS Rsnapshot Server

To do a full backup of our QNAP server I built a CentOS 6.3 machine with plenty of SATA storage. This CentOS server has Rsnapshot installed so that it will not only backup the QNAP, but will also provide incremental backups for accidentally erased or overwritten files on the QNAP.

Webmin
The CentOS server has Webmin installed for easy configuration. Access to webmin is trough port 10000.

QNAP shares work around
For backup up the QNAP the internal Rsync server is enabled and a username and password is set. To prevent the necessity of having to add all shares of the QNAP manually, and updating them for each new future share, we added a special share. This trick is simple, create a new share and manually add the path. This path should simply be "/", this way this share will hold all shares on the QNAP, including the Time Machine shares and others.

Rsnapshot Configuration
Next up was configuring the rsnapshot.conf on the CentOS machine. Contents of config file: (used cat /etc/rsnapshot.conf | grep -v -e ^# to get this output btw)
(ALL SPACES MUST BE TABS!!)

Anacron scheduling
To schedule all backups automatically the following was added to the /etc/crontab file:
0 8,12,16,20 * * * root /usr/bin/rsnapshot hourly
50 23 * * * root /usr/bin/rsnapshot daily
30 23 1,8,15,22 * * root /usr/bin/rsnapshot weekly
10 23 1 * * root /usr/bin/rsnapshot monthly

Linux Server Rebuild

Building a new Ubuntu 10.04 LTS server. The old Ubuntu server needed a replacement of both hardware and software.

Hardware Setup:
A new 19" C2D DFI-ACP machine is used with four SATA drives:
- 250 GB System
- 500 GB Network Share
- 500 GB Backups
- 1 TB Zoneminder Events

Installation:
Ubuntu was installed from a CD without LVM on /dev/sda (250GB) Options chose where:
- Web Server
- File Server
- MySQL
- PostGreSQL

First network settings:
auto eth0
iface eth0 inet static
address 192.168.0.5
netmask 255.255.255.0
gateway 192.168.0.3


sudo ifdown -a
sudo ifup -a

The rest is mainly taken from this guide on www.zoneminder.com

For the ZoneMinder share I set the noatime attribute to reduce write cycles.

sudo chown www-data:www-data events/

Setup PCI capture card
I used a Kodicom 4400R and an Ad-Link RTV24 card, with the following settings the machine booted in 18 seconds!
sudo nano /etc/modprobe.d/bttv.conf

options i2c-algo-bit bit_test=1

sudo adduser www-data video

Edit Apache:
change /var/www to /var/www/zm in /etc/apache2/sites-available/default

Well, that's the first part. The machine is now basically running. I can configure the rest of the ZoneMinder setup and I can see video now. Next up is transferring the data to this new machine, setup Samba, MySQL, backups and Apache.

Updated NFS backup script

We had a problem that when the NFS where all the backups on our network go is offline, a huge TAR is made in the root of the Linux file server. Not good!

After some searching and playing with SH (beware! different from BASH) scripts, I came up with this solution:

#!/bin/sh

/usr/bin/MountSaturnBackup
sleep 2

DT=`stat -f -L -c %T /mnt/backup`
if [ "$DT" = "nfs" ]; then
 tar cpf /mnt/backup/FullBackup.tar --same-owner --exclude=/network/backups/Jupiter --exclude=/var/cache/zoneminder/events/* --exclude=/proc/* --exclude=/media/* --exclude=/d$
fi

The correct thing to do would be to add an else statement and have the script send me an email. I'll look at that later....

DaviCAL installation

Fed up with waiting for Snow Leopard I decided to set up a calender server on our Linux server. After some searching I found out that Davical would be the best solution, especially since we use thunderbird and would like to use lightning as a calerdar client.

I installed DaviCAL on our Ubuntu 7.10 server, this was not very easy! All in all I can't even rember how I exactly did it. My plan is do to the same on a second server and document this step by step.

Most important thing for me is that is all works! There are some disadvantages, but none to big.

Some things to watch out for:

• In the permissions file of PostgreSQL (pg_hba.conf), make sure to post the access control rule at the top of the configuration document!
• The username in the caldav access URL is casesensitive!
• Use this as URL: http:////caldav.php//home/

Since DaviCAL uses PostgreSQL instead of MySQL a extra backup routine is important for me. Our MySQL database is backup, so I added an extra backup script:

#################################################################################################
# PostgresSQL Backup:
mv /network/backups/Database_Backup/Daily6_PostgreSQL_DaviCAL.sql /network/backups/Database_Backup/Daily7_PostgreSQL_DaviCAL.sql

Adding an Axiz PTZ camera to ZoneMinder

ZoneMinder has the ability to control a PTZ (Pan, Tilt, Zoom) through it's user interface.

I added a Axis 213 PTZ dome camera to our ZoneMinder server using the following settings (After turning on PTZ in the Options->System tab (ZM_OPT_CONTROL), and restarting ZoneMinder):

General Tab:

• Source type: remote
• FPS: 6.00 (keep this high or you will get a delay in the image)
  

Soure Tab:

• Remote host name: xxx.xxx.xxx.xxx
• Remote host port: 80
• Remote host path: /axis-cgi/mjpg/video.cgi?resolution=CIF
• 24 bit colour
• Capture width: 384
• Capture Height: 288

Control Tab:

• Control Type: Axis API v2
• Control Device:
• Control Address: xxx.xxx.xxx.xxx:80 (mind the ':' and the port number !!)

And now for the tricky part, at least on my system (Ubuntu 8.04) you need to install a special Perl module:

• sudo apt-get install libmodule-load-perl

Took me about an hour to figure that one out!

Weird Time Machine errors on Leopard Server

When I open the main GIU of the Leopard Server there's always an error pop up on the screen from Time Machine. This error states that 'a' backup malfunctioned, but all backups seem ok.

I looked through the logs and found this: (note that most backups finish ok, just some with the error below)

I always thought that Time Machine does not backup mail stuff, but it apparently does backup parts (useless parts) of the IMAP mail store.

The fix I'm trying is to add the /var/imap/users/ dir to the exclude list in the Time Machine preferences screen. See if this helps....

Rebuilding a Zoneminder system after a Crash

The Zoneminder system setup using this link has had a hard disk crash. Not much of the system could be saved. So we chose to rebuild from scratch.

This time we installed a 160GB disk for the system itself and swap, and a seperate 500GB disk for events and backups of the system.

The start of the guide still applies, but we also did the following:
using fdisk created a 6GB for backups and a 482GB partition for events

Formated both as EXT3 and added the following to /etc/fstab:
/dev/sda1 /backups ext3 defaults,errors=remount-ro 0 1
/dev/sda2 /var/cache/zoneminder/events ext3 defaults,errors=remount-ro 0 1

Set correct permissions for the events dir:
sudo chown www-data:www-data /var/cache/zoneminder/events/

Added a time sync script:
sudo nano /etc/cron.daily/timesync

And added:
#!/bin/sh

ntpdate 0.nl.pool.ntp.org

Then:
sudo chmod 755 /etc/cron.daily/timesync

Fix Video permissions:
chmod 4755 /usr/bin/zmfix

Added a MySQL backup script I also use on our main Linux server:
sudo nano /etc/cron.daily/DB_backup

Added:
#!/bin/sh

mv /backups/MySQL_Backup/Daily6.sql /backups/MySQL_Backup/Daily7.sql
mv /backups/MySQL_Backup/Daily5.sql /backups/MySQL_Backup/Daily6.sql
mv /backups/MySQL_Backup/Daily4.sql /backups/MySQL_Backup/Daily5.sql
mv /backups/MySQL_Backup/Daily3.sql /backups/MySQL_Backup/Daily4.sql
mv /backups/MySQL_Backup/Daily2.sql /backups/MySQL_Backup/Daily3.sql
mv /backups/MySQL_Backup/Daily1.sql /backups/MySQL_Backup/Daily2.sql
mv /backups/MySQL_Backup/Daily.sql /backups/MySQL_Backup/Daily1.sql

mysqldump -r /backups/MySQL_Backup/Daily.sql --all-databases

Then ran:
sudo chmod 755 /etc/cron.daily/DB_backup
sudo mkdir /backups/MySQL_Backup

Set up main backup system using Rsnapshot:

sudo apt-get install rsnapshot

sudo nano /etc/rsnapshot.conf (Watch for tabs instead of spaces!!!)

Contents of config file: (used cat /etc/rsnapshot.conf | grep -v -e ^# to get this output btw)
(ALL SPACES MUST BE TABS!!)

Installed X and setup autologin and auto script run:
sudo apt-get install gdm

sudo apt-get install xorg

On the machine itself (not SSH) ran:
sudo startx

sudo gdmsetup

In gdmsetup I set the user 'zoneminder' as autologin, and set the default session to run the Xclient script.

Create the Xscript:
nano /home/zoneminder/.xsession

And insert:
#!/bin/sh

while ( true )
do
/usr/sbin/xlib_shm-script
sleep 1
done

Then run:
chmod 755 /home/zoneminder/.xsession

Set the correct screen resolution:
sudo apt-get install displayconfig-gtk
sudo displayconfig-gtk

I set this to 800x600, this suits the cameras best

Stop screen blanking by adding this to the /etc/X11/xorg.conf file:
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
EndSection

Create, setup & install the Xlib_shm Zoneminder raw viewing script:
Check the version numbers! not all Xlib_shm version is compatible with each version of Zonderminder!

sudo wget http://dig.hopto.org/xlib_shm/xlib_shm-0.6.3.tgz

sudo tar xfz xlib_shm-0.6.3.tgz

sudo apt-get install libxv-dev

sudo apt-get install build-essentials

sudo apt-get install libmysqlclient15-dev

sudo nano xlib_shm.c
And changed /usr/local/etc/zm.conf into /etc/zm/zm.conf

sudo make all

Place the binary xlib_shm in /usr/sbin/

sudo chown root.root /usr/sbin/xlib_shm
sudo chmod +s /usr/sbin/xlib_shm

For the actual auto starting of xlib_shm I first created a new shell script:
sudo nano /usr/sbin/xlib_shm-script

And added this:
#!/bin/sh
xlib_shm -m 1 -m 23 -m 11 -m 12 -k 0x07a6d0000 -d 40000

Then:
sudo chmod 755 /usr/sbin/xlib_shm-script

Automated mailbackup with Mailbfr

After messing around with cron (which does not work!) and launchd I found a very simpel solution to automatically run mailbfr -b.

I made a new script:
sudo nano /etc/periodic/daily/710.mailbfr

Added this:
#!/bin/sh
mailbfr -b /Volumes/Backups -mo full

Seems to work!

Setting up rsnapshot backup tool on Linux + NFS

Since the Mac server is now sharing it's RAID device with NFS the Linux server can now backup to this share.

Hint:
I'm always struggling to get NFS going for some reason, using the command showmount -e you will get a list of the NFS server's shares. That helps a lot!

I set up a seperate partition on the Mac server as an NFS share only to be accessed by one IP address, that is the IP of the Linux server.

The Linux server has an hourly cronjob to keep the NFS mounted, just to be sure. I placed this file in /etc/cron.hourly/MountNFS-Share Contents:
#!/bin/sh
mount 192.168.0.3:/Volumes/Jupiter-Backups /mnt/backup/

Next I added this following to /etc/crontab on the Linux server:
0 4 * * * root /usr/bin/rsnapshot hourly
50 23 * * * root /usr/bin/rsnapshot daily
40 23 1,8,15,22 * * root /usr/bin/rsnapshot weekly
30 23 1 * * root /usr/bin/rsnapshot monthly

This way the Linux server should backup itself incrementally to the Mac server's RAID device. Also, because the backup goes to the RAID device it will automaticaly be an extra off-site backup.

Installed new backup hardware

The 500GB backup disk in the Mac server is showing a SMART failure warning. So needs replacing. We also wanted a more solid offline backup method.

We placed a DeoNet RAID external USB2.0 next to the server. Backups will now be as followed:

• Mac server Time Machine will backup itself to the RAID device
• Mailbfr running on the Mac server will backup all the mail files to the RAID device
  
• The Mac server will share the RAID using separate partitions, one for the Linux server and one for Time Machine clients on the LAN
  
• The Linux server will backups its data to the shared RAID using rsnapshot and NFS
• Macs on the LAN will backup themselves using Time Machine via the Mac server on the RAID.
  

There are two 1TB discs in the RAID, configured as mirrored RAID 1. There are also two separate discs stored off site. Once every week one of these disks will be swapped with one in the RAID. The RAID will automatically update the disc.

Sendmail changes and correct setup on Linux server

I'm doing some modifying of a PHP script which now needs to be able to send emails. The script (todolist.php) runs on the local Linux server, and is only used internally.

I ran 'sendmailconfig' on the Linux server, this suggested I altered /etc/mail/sendmail.mc. I used the public address of our local SMTP server (Mac Server). After entering this info sendmailconfig continued and reset sendmail.

Immediately emails from the queue started coming in! Pretty cool, and easy!

Extra backup routine for SuperDuper

Added a backup routine and schedule for the backup tool SuperDuper on the Leopard Server.

The script backups only mailbfr's mailbackup directory located on the Leopard Server's backup drive. The backup, of the backup, is backuped as a disk image to the Linux server in it's backup directory. The backup is scheduled for each day at 04:30.

Automated mailback for the Mac OS X Leopard Server by using the 'mailbfr' tool, works great!

I used to use it manually by running:
mailbfr -b /Volumes/Backups/MailBackup/ -mo rotate

I now ran:
mailbfr -i

Which prompted this:

crontab: no crontab for root
cat: /etc/crontab: No such file or directory
There IS NO cron job for mailbfr
if you want to use 'mailbfr' it is recommended that this be added
Would you like me to enable it for you (yes/no)
yes
What time would you like the job to run (24-hour format)?
Please enter the hour (1)
2
Please enter the minutes (0)

Enter the path you would like to backup to? Enter for default (/mailbfrBackups)
/Volumes/Backups/MailBackup
Enter the type of backup you would like? (incremental/full/rotate) Enter for default (incremental)
rotate
The following cron job for 'mailbfr' has been prepared
0 2 * * * /usr/sbin/mailbfr -b /Volumes/Backups/MailBackup --mode rotate
Would you like to add it? (yes/no)
yes
crontab: no crontab for root
The following cron job for 'mailbfr' has been enabled'
0 2 * * * /usr/sbin/mailbfr -b /Volumes/Backups/MailBackup --mode rotate


Backups are now made daily at 02:00 and are stored on the extra backup drive in the Leopard server. The 'rotate' option is used, which means that each day the backup is updated, and is rotated on Saturday.

Mac OS X Webmail

Re-enabled a webmail account on the OS X server, not all worked.

It is apparently very important that you set a user name and an email address in the 'options' section for the users email account. I you do not do this the name will be "SERVER_NAME" and the email address will be @getenv.example.com instead of @example.com (or whatever).

Endless loop for Xlib zoneminder viewer & logging feature

It seems that now and then 'something' goes wrong with the xlib_shm viewer. When we turn on the LCD in the morning the GDM login screen is shown instead of the cameras.

We altered the .xsession file for the auto login user to endlessly re-run the xlib script. The .xsession file now looks like this:

#!/bin/sh

while ( true )
do
/usr/sbin/xlib_shm-script
sleep 1
done


To try and find out what's going wrong we changed /usr/sbin/xlib_shm-script from this:

xlib_shm -m 1 -m 23 -m 11 -m 12 -k 0x07a6d0000 -d 40000


To this:

xlib_shm -m 1 -m 23 -m 11 -m 12 -k 0x07a6d0000 -d 40000 >> /tmp/xlib-log 2> /tmp/xlib-log-dinges


This way we may get some output of errors in the log files.

Added framegrabber & Camera to Zoneminder server

Installed a new (very old BT848 tv tuner card) into the Zoneminder server. Modified the /etc/modprobe.d/options file by adding a number 77 to the card type.

Now 6 camera's up and running!

Full screen Xlib_shm viewer without a window manager

Turned out to be pretty simple (again). I installed GDM instead of XDM, using GDM you can use the tool 'gdmsetup' to enable a default auto login user. Gdmsetup also enables you to choose to run a so called Xclient script instead of a full window manager.

After choosing the Xclient script you need to create a file called '.xsession' in the users home dir.

In this file I added the following:

#!/bin/sh
/usr/sbin/xlib_shm-script


Now when the zoneminder server boots up it will automatically login a dedicated zoneminder users and the Xclient script runs the xlib_shm script I made earlier (see previous post).

Screen Resolution For Xclient Script
Using the tool 'displayconfig-gtk' you can set a screen resolution in which the script will run.
I set this to 800x600 which suits the four Zoneminder camera's best.
