Re; [techtalk] Permissions

[terry]

As Robert said, the O'Reilly books are great.
I have Linux in a Nutshell from O'Reilly and learned
an easier way to change permissions than what I had been
using.  The idea is just to say what you want the
permissions to be for user, group, and other.  Here's
some examples:

/home/terry/temp>ls -la
total 16
drwxr-xr-x   2 terryusers4096 Jun 19 00:56 .
drwx--  10 terryusers4096 Jun 19 00:55 ..
-rw-r--r--   1 terryusers   9 Jun 19 00:56 file_one
-rw-r--r--   1 terryusers  11 Jun 19 00:56 file_two
   
   
/home/terry/temp>chmod u=rwx, g=rw, o=x file_one
chmod: g=rw,: No such file or directory
chmod: o=x: No such file or directory

(Oops, I guess it doesn't like spaces- try
again) 
     
/home/terry/temp>chmod u=rwx,g=rw,o=x file_one

(Meaning that I,user, can read write xecute, group can read write, other
can execute)  
/home/terry/temp>ls -la
total 16
drwxr-xr-x   2 terryusers4096 Jun 19 00:56 .
drwx--  10 terryusers4096 Jun 19 00:55 ..
-rwxrw---x   1 terryusers   9 Jun 19 00:56 file_one
-rw-r--r--   1 terryusers  11 Jun 19 00:56 file_two

(It worked!)

/home/terry/temp>chmod u=rw *

(user can read and write all files in directory)
/home/terry/temp>ls -la
total 16
drwxr-xr-x   2 terryusers    4096 Jun 19 01:14 .
drwx--  10 terryusers    4096 Jun 19 00:55 ..
-rw--x   1 terryusers   9 Jun 19 00:56 file_one
-rw---   1 terryusers  11 Jun 19 00:56 file_two

/home/terry/temp>chmod g=  *
(group cannot do anything to any files - leaving a blank removes
permissions)

/home/terry/temp>ls -la
total 16
drwxr-xr-x   2 terryusers4096 Jun 19 01:14 .
drwx--  10 terryusers    4096 Jun 19 00:55 ..
-rw--x   1 terryusers   9 Jun 19 00:56 file_one
-rw---   1 terryusers  11 Jun 19 00:56 file_two

[techtalk] .htaccess problem

[terry]

I'm trying to enable passwords for access to
my apache webserver.

Can someone spot where I am going wrong?
Thanks for your help.

I have edited the httpd.conf file. I have:


# First, we configure the "default" to be a very restrictive set of
# permissions.
#

Options -FollowSymLinks
AllowOverride None


#
# Note that from this point forward you must specifically allow
# particular features to be enabled - so if something's not working as
# you might expect, make sure that you have specifically enabled it
# below.
#

#
# This should be changed to whatever you set DocumentRoot to.
#


#
# This may also be "None", "All", or any combination of "Indexes",
# "Includes", "FollowSymLinks", "ExecCGI", or "MultiViews".
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
Options Indexes -FollowSymLinks +Includes

#
# This controls which options the .htaccess files in directories can
# override. Can also be "All", or any combination of "Options",
"FileInfo",
# "AuthConfig", and "Limit"
#
AllowOverride AuthConfig Limit

#
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all
_

Then in the web root directory I have the .htaccess file

AuthName "Page page"

AuthType Basic
AuthUserFile /usr/local/httpd/htdocs/.htpassword
order allow,deny
Allow from all

require valid-user

-
the .htpassword is in the same directory (for now, I've also tried
putting
it in a users home directory)

 I created using htpasswrd -c .htpassword username
___

I get the following error:

Internal Server Error

The server encountered an internal error or misconfiguration and was
unable to complete your request.

Please contact the server administrator, root@localhost and inform them
of the time the error occurred, and anything
you might have done that may have caused the error.

More information about this error may be available in the server error
log.

---

I tried putting similar .htaccess and .htpassword files
in a user's public_html directory, where they had no effect.

Thanks for any tips.

It says:
 /usr/local/httpd/htdocs/.htaccess: AuthName not allowed here

I tried moving the .htaccess file into a subdirectory - still
get same error on that directory.

I'm not sure I understand - do you mean:



AuthName "Page page"

AuthType Basic
AuthUserFile /home/ev/public_html/.htpassword
order allow,deny
Allow from all

require valid-user
satisfy any

This had no effect - no error message, no request for password, just the
webpage.

Config file says the following, but yes, I meant to move it
once I got it working - I wanted to be sure it was finding the file.
Got a little frustrated and started trying random stuff, I guess.

# The following lines prevent .htaccess files from being viewed by
# Web clients.  Since .htaccess files often contain authorization
# information, access is disallowed for security reasons.  Comment
# these lines out if you want Web visitors to see the contents of
# .htaccess files.  If you change the AccessFileName directive above,
# be sure to make the corresponding changes here.
#
# Also, folks tend to use names such as .htpasswd for password
# files, so this will protect those as well.
#

Order allow,deny
Deny from all

Re: [techtalk] .htaccess problem

[terry]

Thank you Almut and Elizabeth -
You got me to thinking and I discovered that 
my mistake was one of those really dumb, right under
your nose kind of things.  I was not restarting
the webserver, so the changes to httpd.conf
were having no effect.

Reminds me of programming - "I've tried A!
I've tried B! I've tried C! and my program
is still giving me the exact same output!
Oops, I forgot to save the changes before recompiling."

Thanks again for your replies.

Most of the material and books I've read on Linux seem to skim
over pre-installation. Something that would help (especially
those coming from M$) would be a thorough explanation of disk
partioning, Linux filesystem ( it took several installs for
me to finally get the partioning for / , /usr , /home etc..
set the way I needed it) and steps for determining io and irqs
of the sound cards, modems, etc... Most people coming from
Windoze never have to manually configure such things and will
find it very confusing if the distro they choose doesn't auto-
detect all their hardware.
I am, of course, assuming this will all be geared towards users
completely unfamiliar with Linux or *nix.

RE: [techtalk] truncated file names

[Terry Randall]

from the fstab manpage:

The fifth field, (fs_freq), is used for these filesystems by the dump(8)  
command to determine which filesystems need to be dumped.  If the fifth
field is not present, a value of zero is returned and dump will assume
that the filesystem does not need to be dumped.
   The  sixth field, (fs_passno), is used by the fsck(8) program to
determinethe order in which filesystem checks are done at reboot
time.   The  rootfilesystem  should  be specified with a fs_passno
of 1, and other filesys-tems should have a fs_passno of
2.  Filesystems within  a  drive  will  bechecked  sequentially,
but filesystems on different drives will be checkedat the same
time to utilize parallelism available in the hardware.  If the
sixth  field  is not present or zero, a value of zero is returned and fsck
will assume that the filesystem does not need to be checked. 


I would assume you DO NOT want to fsck a windows mount, so I would use
a "0" here.

[techtalk] dual boot/ linux writing into win98 partition

[Terry Yesse]

Hi all-
I work in a student computer lab that uses Win 98.
We reload the software on a regular basis as the
windows files inevitably get messed up.

I was wondering if it would be possible to make the
machines dual boot Linux and Windows and use Linux
to reload the Win software over the network.  Norton Ghost
would be the usual solution to this problem, but I'd 
rather have an excuse to load Linux on the machines!

The parts I'm unsure about:
  1. how to get Linux to write into the Windows partition
  2. will just copying the files from an installed windows work?
 (how to I get the right stuff into the boot sector etc.?)

Has anyone done anything like this?  Is there a better way?

Any pointers to HOWto's, man pages, how you did it, etc
would be much appreciated.

TIA, 
  Terry
