There is no problem to do this... the variablename and parametername are to
different things.

I think i have to use the binmode only on Windowsserver. On Unixservers this
cgi function will not work.

I know it shouldn't matter, but it seems to be a bad idea to name a
variable and a file handle the same...IMHO.  Could cause confusion.


I would do an open as binary here, otherwise the output will always be
ascii (I think...would have to go back and do some reading on that).

I'm not too familiar with the CGI module, but using webmin's API you could
write :

&ReadParseMime();
my $full_filename="$skin_dir"."/".$in{'file_name'};
open(OUTPUT, ">$full_filename");
print OUTPUT $in{'file'};
close(OUTPUT);

Problem with fileupload

[Gehrigal - W. <we...@ge...>]

Hi all,

at the moment i am working on a new module for webmin.
In this module the user should be able to upload files.
But there is a bug in my perlscripte, and so the uploaded file will be
allways 0 byte.

.....
my $q = new CGI;

my $file        = $q->param("file") || &error( "No File received!");
my $file_name   = $q->param("file_name") || & error ( "There was no
Filename!");
my $fh          = $q->upload("file");
my $buffer      = "";


my $full_filename="$skin_dir"."/"."$file_name";

open(OUTPUT, ">$full_filename");
while (read( $fh, $buffer, 512000) ){ print OUTPUT $buffer;}
close (OUTPUT);

......


Any ideas?

thx

Any contents of the file /etc/webmin/modulename/config will be read into
the global %config hash when your module calls &init_config(). Every CGI
program should call that function, usually by require'ing a library that
does it.

Does that make things any clearer?

special configuration

[Guillaume D. <gui...@in...>]

Hello,
i've made my own module for webmin.
When i install it, I install an classical webmin and after i install the new
repository in /usr/libexec/webmin.
I change the *.acl and all the category files in order to use mine.
I have also made under /etc an "emplacement" repository where i've put an
config file as described in the module document.
My problem is that webmin seem to not use it...
Of course, everything in the script is ok because  they are working fine
under my development plateform.(for information i use the
foreign_config(module) function.

Do i miss something in configuration file ?

i use webmin 0,970

Re: webmin login?

[Joe C. <jo...@sw...>]

There is no existing code that does this.

But you could get halfway there without code...Setup anonymous group so 
it has permission only to use the Webmin users module.  The user can 
then create whatever user they want with full admin permissions.  This 
doesn't solve the problem of anonymous users still having this 
capability after the first such user is created.

To do what you're asking requires a new module (perhaps with some small 
bits stripped out of the Webmin Users and Groups module).  This can then 
be installed as the only module an anonymous user can use.  And you can 
include self-destruction (or self-disabling) code to make it go away 
after a root user is created.

First, I'd suggest you look at anonymous module permissions and how they 
work.  Then write a module that does what you want to do, which you give 
permission to use to the anonymous group.  Then instruct your users on 
how to get to the anonymous module (you could also hack Webmin so that 
it automatically goes to anonymous if no users are configured...).  Any 
of this requires some work, and reading a lot of Webmin code.

Now that I'm thinking of all that is going to go into something like 
this, I think I'd hire Jamie to do it for me!  ;-)

Re: webmin login?

[Joe C. <jo...@sw...>]

If I wanted to accomplish something like this, I would start with an 
anonymous module, which only has the ability to create a root user once 
and then converts itself to non-anonymous or simply removes itself.  Be 
careful with this sort of thing, though...it is asking for security holes.

webmin login?

[support <su...@ea...>]

howdy,

I was wondering if the webmin login page can be disabled once.

what i would like to do...

For example, the first time webmin is used you go directly into webmin menu,
then the user can go into "create account" menu and setup "login and
password"...

then after the "root' account is created, all cookies, etc.. from the login
page are enabled...

thanks,

diego

Yes - you could create your own version of session_login.cgi in your

directory. Just make sure that it does all the same things with cookies
as the original does, and outputs a login form with the same fields.

Actually the ppp module (under serial port configuration) set that up
correctly, it put in the following line:
