Question about filemanager svn r26710

Pongracz_Istvan-2 2009-03-31 13:20:39 UTC #1

Hi Ralf,

First thank you for the patch r26710

I installed it and I tried to figure out, how to use the new (exec)
function.

I added ‘sh’ as script extension to the SCRIPT_EXTENSION_PREG constant and
after I uploaded a script file called foo.sh.

Could you explain in short, how to use this function? Is it only working in
CLI?

Thank you,

István

Hi István,

sorry to say, the exec option does something different: It allows or
prevents (default) to upload scripts. This is obviously important
securitywise.

If you add .sh as extension, you only stop yourself from uploading shell
scripts

Hi Ralf,

You win

Anyway, I tested it, but I still able to upload .php and .sh files to the
server.
Do I need something else or maybe a bug inside?

Cheers,
István

How do you upload them, via GUI (filemanager) or WebDAV?

I can reproduce that, meaning I cant upload .php files to the vfs, IF
the backend is filesystem://

I eg. mounted my docroot into the vfs:

filemanager/cli.php mount --user root_admin --password *****
‘filemanager://default/var/www/html?group=Admins&mode=075’ /html

Now I can browse the docroot (even read .php files), but I cant modify
or upload new .php files.

Hi István,

How do you upload them, via GUI (filemanager) or WebDAV?

I am using only the GUI (filemanager) without any magic backend, using
sqlfs. The default (I guess) method to use filemanager.
In my configuration it is not possible to mount using filemanager’s
webdav.php, because I got a never-ending loop to give my
username/password…

So, maybe this is the normal behaviour when one uses sqlfs.

I can reproduce that, meaning I cant upload .php files to the vfs, IF
the backend is filesystem://

I guess, for me it is not really clear, how the backend is working…

I eg. mounted my docroot into the vfs:

filemanager/cli.php mount --user root_admin --password *****
‘filemanager://default/var/www/html?group=Admins&mode=075’ /html

Now I can browse the docroot (even read .php files), but I cant modify
or upload new .php files.

So, cli is used to access the filesystem itself under egw-filemanager?

I only used the GUI, but I will start playing with the cli to see its
possibilities.

Cheers,
István

Hi Istvan,

seems you got quite a lot wrong

You can think of the new eGW VFS like of a Linux fstab. Just run

filemanger/cli.php mount --user root_admin --password *****

you’ll get something like:

sqlfs://$host/ /
links://$host/apps /apps

Now you can mount other backends into the VFS, eg.:

filemanager/cli.php mount --user root_admin --password *****
‘filemanager://default/var/www/html?group=Admins&mode=075’ /html

A filemanger/cli.php mount shows then:

sqlfs://$host/ /
filesystem://default/var/www/html?group=Admins&mode=075 /html
links://$host/apps /apps

When you acces the VFS now (via filemanger or WebDAV) you see a new
folder /html with all your docroot under it. eGW admins can now use it
to upload stuff (with the exception of .php files).

You can also enable the .php or script upload by using the following
mount command:

filemanager/cli.php mount --user root_admin --password *****
‘filemanager://default/var/www/html?group=Admins&mode=075&exec=1’ /html

So from eGW 1.6 on you can mount other backends into the vfs and access
them via eGW’s webgui (filemanger) or WebDAV.

Hi Istvan,

seems you got quite a lot wrong

You can think of the new eGW VFS like of a Linux fstab. Just run

filemanger/cli.php mount --user root_admin --password *****

you’ll get something like:

sqlfs://$host/ /
links://$host/apps /apps

I used this formula, because I use other than ‘default’ as domain name:
filemanger/cli.php mount --user root_admin --password ***** --domain
mydomain

So, I got only an emtpy line and this message: Root access granted!

Probably something wrong?

I got a list, using this formula (note that, localhost could be anything
else, the results is the same):
filemanager/cli.php --user user1 --password pwd1 --domain mydomain ls -l
vfs://localhost/
cli ls (long=1, numeric=0, recursive=0)
ls: no such file or directory!
cli vfs://localhost/ (long=1, numeric=0, recursive=0)

/:
d------r-x 2 root root 0 2008-10-17 17:13:36 apps
d------r-x 2 root root 0 2008-10-17 17:13:36 home

Now you can mount other backends into the VFS, eg.:

filemanager/cli.php mount --user root_admin --password *****
‘filemanager://default/var/www/html?group=Admins&mode=075’ /html

I successfully mounted my website root directory under /html, but using
filesystem instead of filemanager (1st of April It is really fine.

filemanager/cli.php mount --user root_admin --password *****
‘filesystem://default/var/www/html?group=Admins&mode=075’ /html

Now, the filemanager/cli.php mount --user root_admin --password *****
–domain mydomain shows this:
Root access granted!
sqlfs://$host/ /
filesystem://something/var/www/virtual/mysite.hu?group=Admins&mode=075 /html
links://$host/apps /apps

Ok, after it, the only question to myself, what is the problem with my
webdav.php access, because I got an infinite loop to give my
username/password, even I give correct credentials. Do I need apache webdav
module too?

István

Strange, maybe that’s the behaviour if you have run mount and the
default fstab is used.

I got a list, using this formula (note that, localhost could be anything
else, the results is the same):
filemanager/cli.php --user user1 --password pwd1 --domain mydomain ls -l
vfs://localhost/
cli ls (long=1, numeric=0, recursive=0)

cli vfs://localhost/ (long=1, numeric=0, recursive=0)

d------r-x 2 root root 0 2008-10-17 17:13:36 apps
d------r-x 2 root root 0 2008-10-17 17:13:36 home

That’s just a ls.

Now you can mount other backends into the VFS, eg.:

filemanager/cli.php mount --user root_admin --password *****
‘filemanager://default/var/www/html?group=Admins&mode=075’ /html

No, you do NOT need mod_webdav. I have no idea what’s the problem with
our WebDAV access. We have many installs using it with either 1.6 or
trunk. Sorry

I think yes, because there is no ‘default’ domain

No, you do NOT need mod_webdav. I have no idea what’s the problem with
our WebDAV access. We have many installs using it with either 1.6 or
trunk. Sorry

I only expect this strange behaviour and seems there is nothing in the
error_log.
I use fcgid, instead of fastcgi or mod_php on debian lenny. One time I will
dig deeper to find out, why this kind of situation occures and how to solve
it. At this moment this feature is on the “wish-list” but not critical

Thank you again and have a nice day.

Hi István,

there are some problems with fcgi:

a) SCRIPT_NAME is set wrong by php-fcgi:
http://bugs.php.net/bug.php?id=19656

If you google for it, you find many possible solutions:
http://www.google.de/search?q=php+fcgi+SCRIPT_NAME&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:de:official&client=firefox-a

For lighttpd we use the following in our header.inc.php:
// required for WebDAV with lighttpd
if (stripos($_SERVER[‘SERVER_SOFTWARE’],‘lighttpd’) !== false &&
isset($_SERVER[‘ORIG_SCRIPT_NAME’]))
{
$_SERVER[‘SCRIPT_NAME’] = $_SERVER[‘ORIG_SCRIPT_NAME’];
}

b) HTTP_CONTENT_LENGTH header set eg. by lighttpd, that’s fixed see
http://www.egroupware.org/viewvc/egroupware/trunk/egw-pear/HTTP/WebDAV/Server.php?r1=26663&r2=26662&pathrev=26663

Do you think, there are some problems with fcgid?
I use this: http://fastcgi.coremail.cn/ with php 5.2.6 and I only find this
kind of problem:

cannot connect to the webdav.php directly from Nautilus, because I get back
the login window… Maybe only a PEBCAK
Update: I have a feeling, this is a PEBCAK

I have no other issues, even rpc.php for syncml.

I will spend more time to find out what is the problem…

Seems it is not a pebcak, but something weird in my system.
When I am logged in into egroupware and I try to access the folder in
Firefox using the webdav.php it displays the folder correctly, without any
problem.
But if I am logged out and I try to access my folder using webdav.php, the
effect is the same: infinite loop with Login name: Password: and does not
matter, what I write inside.

Just log into eGW and then call the following url:

http://your.domain.com/egroupware/admin/phpinfo.php/home/ralf

Then check and compare the values for the following _SERVER vars:

_SERVER[“REQUEST_URI”] /egroupware/admin/phpinfo.php/home/ralf
_SERVER[“SCRIPT_NAME”] /egroupware/admin/phpinfo.php

that’s looking good.

I think the problem is with the basic auth and your system

Unfortunately I think the same
I hacked the authentication code and webdav.php but the problem still
exists.

Anyway, I got an idea and how to dig deeper. If I find a solution, I will
report it.

Until that, check this brand new blog, just started by me. I try to keep it
up-to-date and as informative as the first post.
You can check here, vote included: http://pongraczi.blogspot.com/
