TMG:Automatic Text CDR Retrieval

This procedure shows how to configure a Tmedia to send its CDR files to a remote server automatically.

Warning: If the destination is a Windows server, you require to install software that supports scp (i.e. freeSSHd). Not tested by TelcoBridges personnel.

Setup SSH Public/Private Key

This will enable the Tmedia to send files to the remote host without asking for a password:

• Connect to the Tmedia using SSH as root

• Create Tmedia public/private dsa key pair

ssh-keygen -t dsa

Note: Do not add a pass phrase, simply press enter until the key pair is generate.

• Append the content of the public key to the remote host authorized keys

Tmedia public key location

/root/.ssh/id_dsa.pub

Remote Host authorized keys location

~/.ssh/authorized_keys

Configure the Tmedia to Send files

• Open the file configuration

vim /usr/bin/tbcopycdr

• Set the following variables in the file
  • TMG_CDR_DIR (Tmedia directory where the CDR are located)
  • REMOTE_DIR (Remote host directory where the CDR will be send)
  • REMOTE_USER (Remote host user)
  • REMOTE_HOST (Remote host name or Ip address)
  • ERASE_AFTER_SEND (TMedia will erase the CDR files locally or not after a successful send, default true)

Note: if you set ERASE_AFTER_SEND to false the CDR text file will be available in the /home/telcobridges/cdr/ directory and rename *.gz.already_send.

Example: Send the files to the home directory of the root user of host 10.10.10.10

TMG_CDR_DIR=/lib/tb/toolpack/setup/12358/2.5/apps/gateway/cdr_logs/
REMOTE_DIR=~/
REMOTE_USER=root
REMOTE_HOST=10.10.10.10
ERASE_AFTER_SEND=true

Validate Setup Configuration

• Run the tbcopycdr script with the -v option

tbcopycdr -v

If no error were seen on the shell, your configuration is correct. Also, you should have a hello_world.log file on the remote host.

Configure Tmedia to send the files automatically

• Create a new crontab on the Tmedia

crontab -e

• Add new line with the cron configuration

Example:

Frequency	Cron Configuration
Every 10 minutes	*/10 * * * * /usr/bin/tbcopycdr
hourly (top of the hour)	0 * * * * /usr/bin/tbcopycdr
daily (midnight)	0 0 * * * /usr/bin/tbcopycdr
