[GLLUG] Samba + Linux, FreeBSD, and (sigh) Windows

You could always make the user enter the password by not specifying it
on the command line.  Here is a batch file I use to log into a separate
domain that I use frequently.  It's only accessible via VPN, hence the
pings, but it handles most of the common logon issues that 'NET USE'

--- cut ---

@echo off
set count=1
color 0b
ping -n 1 -w 2000 2>&1 | findstr /C:"Reply from" >nul 2>&1
if errorlevel 1 goto Fail
net use x: /delete
net use x: \\\Shares /user:PaulM *
if errorlevel 1 goto Login
goto End
echo Unable to login to the server.
echo Check your password and try again.
if "%count%" == "3" (
   goto Failed
set /a count=%count%+1 >nul
goto Success
echo Unable to communicate with server.
echo Are you sure that you are connected to that network?
goto End
echo Unable to log in to the server.
echo (Was CAPSLOCK on?)
echo Check username and password and try again.
goto End

No problem. Normally, Evolution will wrap automatically if I select
Format -> Wrap Lines, but it wasn't working for me, so I did it by hand.

This basically looks like a command-line version of the same thing that
I was doing in the GUI. So I guess the only way to do what I want to do
is create a batch file or something that gets run on each logon. I don't
relish the idea of storing the password in plaintext (even in a
Windows-encrypted file), but maybe I can hack up a quick program to at
least obfusicate it like FreeBSD's "smbutil crypt" does.

...Found the source for the "simplecrypt" algorithm from FreeBSD's smbfs
and it looks like I won't have to do much of anything to make it work
under Windows. Yes, I like making work for myself. Thanks, Paul!
