I have been reviewing Louis' script
(4-setup-sernet-samba4-MEMBER-wheezy.sh) and within the following line
(310) is an odd character combination.
if [ ${SMBPRINTING} = no ]; then
echo "==========Disable Printing ==============================="
sed -i '49a\n # disable printing completelyn load printers = non
printing = bsdn printcap name = /dev/nulln disable spoolss = yesn'^M
<<<<<<< WHAT?
/etc/samba/smb.conf
fi
I am using vi editor (Debian 7.7.0) and noticed "^M" at the end of the
line. This character combination appears twice within the script. Both
time as a unique font color. Here listed above and finally on the last
line of the script. In 'test' removing the character combination the
cursor responds as though this is a single character. In other words, a
single keystroke removes both characters.
Is this a necessary character for the script to function properly? Or is
it rogue and causing some unforeseen issues?
(I feel bad raising this question while Louis is on a holiday. Many of
us have been using his script for some time now and history indicates
that they are working scripts. And I for one really appreciate all the
work that went into them.)

In my instance of vi, it creates a newline without showing the ^M that I definitely remember seeing in my users (windows) logon scripts. Cheers! d.

If you are interested, I now have a script to install a member server using samba packages from debian backports instead of using the sernet packages. I was prompted to write this because I could not get a sernet member server to allow me to login via smbclient or 'caja' on LinuxMint. Rowland

I have been unable to get a member server to work with any form of ADDC, and I've been trying for a week. Just crashed out last night with Louis' script (both automated, and me working through it step by step). What version of samba is in the backports? and as a side note to Bob -- If I open the script directly from the website using gedit to open it from firefox (on a different, older ubuntu machine) I get all the correct formatting (I spent several hours working through it and all its assumptions, yesterday). But I haven't looked at it with vi. Maybe I will. maybe the sed command is showing up here broken incorrectly because of word-wrap in your newsreader client? Cheers! d.

Historically, if the "^M" had had any effect to the script, it would have been dealt with before now. So, I can ignore it. Thank you for the education. I have been using linux for 10 years or so and still learning something new everyday.

For many reasons I have restored my machine to pre-sernet-samba (basic Debian server install) and was going to run Louis script again.
