Zabbix icmpping not working cnt=0 rcv=0

After doing a clean install of zabbix-proxy on a CentOS 6 server, all our icmpping / icmppingsec items started to return zero values.

Zabbix debug log showed following lines:

[code]
31790:20140611:073610.004 In process_ping() hosts_count:1
31790:20140611:073610.004 /tmp/zabbix_proxy_31790.pinger

Compiling PHP for Zabbix 2.2 frontend

To compile PHP for Zabbix 2.2 frontend you will need to use the following keys:

[code]
./configure –enable-mbstring –enable-sockets –with-mysql –with-mysqli –with-ldap –enable-fpm –enable-bcmath –with-gettext –with-xmlrpc –with-openssl –with-mcrypt –with-gd –with-zlib –with-freetype-dir=/usr/include/freetype2 –with-jpeg-dir=/usr/lib
[/code]

PHP ini required values (minimal):

[code]
memory_limit = 128M
post_max_size = 16M
upload_max_filesize = 2M
max_execution_time = 300
max_input_time = 300
session.auto_start = 0
[/code]

Zabbix backup script without history data

Here is simple backup script for Zabbix 2 configuration data (hosts, items, templates etc). It will not backup history/event/trend data, so backup file is relatively small.

Just replace ZBX_DB and ZBX_USER with Zabbix database name and username.

[code]
mysqldump -u ZBX_USER -p ZBX_DB \
–ignore-table=ZBX_DB.acknowledges \
–ignore-table=ZBX_DB.alerts \
–ignore-table=ZBX_DB.auditlog \
–ignore-table=ZBX_DB.auditlog_details \
–ignore-table=ZBX_DB.escalations \
–ignore-table=ZBX_DB.events \
–ignore-table=ZBX_DB.history \
–ignore-table=ZBX_DB.history_log \
–ignore-table=ZBX_DB.history_str \
–ignore-table=ZBX_DB.history_str_sync \
–ignore-table=ZBX_DB.history_sync \
–ignore-table=ZBX_DB.history_text \
–ignore-table=ZBX_DB.history_uint \
–ignore-table=ZBX_DB.history_uint_sync \
–ignore-table=ZBX_DB.trends \
–ignore-table=ZBX_DB.trends_uint \
| gzip > zbx_db.sql.gz

Last Ad Free Skype version

*UPDATE*
If you want to use latest Skype version just add following line to hosts file (C:\Windows\System32\drivers\etc):

[code]
127.0.0.1 rad.msn.com
127.0.0.1 live.rads.msn.com
127.0.0.1 ads1.msn.com

[/code]

Today I received a Skype update that started to show advertisements in chat windows.
This was unacceptable for me, so I decided to downgrade Skype to latest ad-free version, which seems to be 6.9.0.106.

You can download old Skype version without ads from here:

http://download.skype.com/msi/SkypeSetup_6.9.0.106.msi

Mirror:
http://mirror.szepe.net/software/SkypeSetup_6.9.0.106.msi

To prevent Skype from updating automatically go to:

Tools -> Options… -> Advanced -> Automatic updates and click “Turn off automatic updates’.
