Yesterday I installed Ubuntu Server 14.04 on my machine (D2500 board with integrated graphics): after finishing install and rebooting the monitor does not get a signal and goes into standby right after boot process end.
Oss.: BIOS was displayed normally !
Situation
1) Monitor in Standby
2) SSH available
3) System booted “correctly” (except graphics)
I get this error in /var/log/syslog
[drm:cdv_intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up

I love Bacula, really, a lot !
In my company we use it to backup all the server (Linux & Windows) inside the LAN !
However, it has a big drawback: when the client-server connection drops backup process starts over again.

For this reason we started a long time to use for backup via WAN Burp, an open source backup solution that has the ability to continue interrupted backups. Continue reading
Step 1
Check if sendmail is compiled with TLS (for encryption) and SASL (for authentication). This is the command to use to check it.
#/usr/sbin/sendmail -d0.1 -bv root
You must read something like “Compiled with…STARTTLS”
Att.: If you’ve installed sendmail using yum, TLS support is present !
Step 2
Install all these packages
# yum install sendmail sendmail-cf cyrus-sasl-plain cyrus-sasl-md5
Step 3
Create certificates
# cd /etc/pki/tls/certs # make sendmail.pem
