Was working on Asterisk configuration with CISCO 7940 IP phones.
There are many links which let configure this phone, this is just an overview of what I did to get this up and running
Configuring AsteriskNow is very simple. Below are the details to setup a IP-PBX.


Requirement
  1. Old CPU laying somewhere.
  2. IP Phone (Cisco 7940/7960)
  3. DHCP and TFTP Server (for Firmware upgrade)

Steps
  1. Download AsteriskNOW
  2. Configure Asterisk. (More howto later, for now important is to create users without NAT)
    1. Create a Trunk
    2. Create a Dialplan
    3. Create users (On catch here is when we create a User make sure to uncheck "NAT")
  3. Configure IP Phone used the link here which is very helpful (Attached are files required firmware / conf files etc).

Thats it !! IP phone should be up and running.

Cloudera Manager - Duplicate entry 'zookeeper' for key 'NAME'.

We had recently built a cluster using cloudera API’s and had all the services running on it with Kerberos enabled. Next we had a requirement to add another kafka cluster to our already exsisting cluster in cloudera manager. Since it is a quick task to get the zookeeper and kafka up and running. We decided to get this done using the cloudera manager instead of the API’s. But we faced the Duplicate entry 'zookeeper' for key 'NAME' issue as described in the bug below. https://issues.cloudera.org/browse/DISTRO-790 I have set up two clusters that share a Cloudera Manger. The first I set up with the API and created the services with capital letter names, e.g., ZOOKEEPER, HDFS, HIVE. Now, I add the second cluster using the Wizard. Add Cluster->Select Hosts->Distribute Parcels->Select base HDFS Cluster install On the next page i get SQL errros telling that the services i want to add already exist. I suspect that the check for existing service names does n

Zabbix History Table Clean Up

Zabbix history table gets really big, and if you are in a situation where you want to clean it up. Then we can do so, using the below steps. Stop zabbix server. Take table backup - just in case. Create a temporary table. Update the temporary table with data required, upto a specific date using epoch . Move old table to a different table name. Move updated (new temporary) table to original table which needs to be cleaned-up. Drop the old table. (Optional) Restart Zabbix Since this is not offical procedure, but it has worked for me so use it at your own risk. Here is another post which will help is reducing the size of history tables - http://zabbixzone.com/zabbix/history-and-trends/ Zabbix Version : Zabbix v2.4 Make sure MySql 5.1 is set with InnoDB as innodb_file_per_table=ON Step 1 Stop the Zabbix server sudo service zabbix-server stop Script. echo "------------------------------------------" echo " 1.

Access Filter in SSSD `ldap_access_filter` [SSSD Access denied / Permission denied ]

Access Filter Setup with SSSD ldap_access_filter (string) If using access_provider = ldap , this option is mandatory. It specifies an LDAP search filter criteria that must be met for the user to be granted access on this host. If access_provider = ldap and this option is not set, it will result in all users being denied access. Use access_provider = allow to change this default behaviour. Example: access_provider = ldap ldap_access_filter = memberOf=cn=allowed_user_groups,ou=Groups,dc=example,dc=com Prerequisites yum install sssd Single LDAP Group Under domain/default in /etc/sssd/sssd.conf add: access_provider = ldap ldap_access_filter = memberOf=cn=Group Name,ou=Groups,dc=example,dc=com Multiple LDAP Groups Under domain/default in /etc/sssd/sssd.conf add: access_provider = ldap ldap_access_filter = (|(memberOf=cn=System Adminstrators,ou=Groups,dc=example,dc=com)(memberOf=cn=Database Users,ou=Groups,dc=example,dc=com)) ldap_access_filter accepts standa
