MG's Notes

Run:

dumpe2fs -h /dev/sda1

or

tune2fs -l /dev/sda1

where /dev/sda1 is you partition, and search for Block size:

for x in `find * -maxdepth 0 -type d`;
do
  # Translate Caps to Small letters
  y=$(echo $x | tr ‘[A-Z]‘ ‘[a-z]‘);

  # check if directory exits
  if [ ! -d $y ]; then
     echo “mv $x $y”
     mv $x $y;
  fi
done

NOTE: -maxdepth 0 is for directories in curent dir. If you want to rename in depth use -depth instead

1. Replace all PIX_FMT_RGBA32 with PIX_FMT_RGB32

SSHD has a little bug when do you want to use ClientAliveCountMax in combination with ClientAliveInterval, so if you want to work try this:

TCPKeepAlive yes
ClientAliveInterval 3600
ClientAliveCountMax 0

this should disconnect iddle session older then 1h.

Add MX records to your DNS like this:

10 mail.yourdomain.com
20 backup.yourdomain.com

You will also need to add DNS entries that correspond with the new server so that backup.yourdomain.com points to the IP address of your back-up mail server.

When the mail server at the IP address relating to mail.yourdomain.com is not available mail will be sent to backup.yourdomain.com

and then add the following line in /etc/mail/mailertable:

yourdomain.com smtp:mail.yourdomain.com

Next we need to add this to the mailertable database.
Type:
# makemap hash /etc/mail/mailertable.db < /etc/mail/mailertable

And then append the following lines to the bottom of your access file.

To:yourdomain.com RELAY

Now you should have something like this:
# by default we allow relaying from localhost…
localhost.localdomain RELAY
localhost RELAY
127.0.0.1 RELAY
To:yourdomain.com RELAY

now run:
makemap hash /etc/mail/access.db < /etc/mail/access

Now restart the sendmail service to make the changes complete
Type:
# service sendmail restart

 If you are running vsftpd in standalone mode, add the “listen_port” directive in vsftpd.conf,like this:

listen_port=30

If you are running vsftpd from an inetd or xinetd program, this becomes an inetd or xinetd problem. You must change the inetd or xinetd configuration files (perhaps /etc/inetd.conf or /etc/xinetd.d/vsftpd).
