vQadmin

Hi Roberto,

If you are using vpopmail with mysql backend and enabled mysql limits option (--enable-mysql-limits), vqadmin is pretty much useless, because it is not aware of this this option. It creates ".qmailadmin-limits" in the domain folder, but vpopmail does not care at all (due to --enable-mysql-limits).

- That annoyed me a little bit, so I fixed it. Now vqadmin is aware of mysql-limits, and updates the database as necessary.

- I also fixed a core-dump due to SIGILL caused by memcpy. I changed it to memmove, as suggested on this link:

The memcpy() function shall copy the first n bytes pointed to by src to the buffer pointed to by dest.
Source and destination may not overlap. If source and destination might overlap, memmove() must be used instead.

- I added missing limits and permissions, changed the UI to be more user-friendly.

The patch is here. It can be applied cleanly on your "vqadmin-2.3.7_20200226.patch".

Feel free to share it on your website.

Ali, I had to include <stdint.h> to avoid a compilation break:

In file included from vqadmin.c:25: 
global.h:151:9: error: unknown type name ‘uint64_t’ 
 151 | typedef uint64_t storage_t;

Hi Roberto

Thanks a lot for having a look at the patch.

The vqadmin UI looks archaic, but it gets the job done anyway. We can replace it altogether with a fancy UI in the future, but for the time being I would like to dig deeper into vpopmail. I feel like there is a lot of room for improvement there. We may add sqlite or firebird support to vpopmail. Or we can enhance the existing functionality.

Anyway, thanks again for this wonderful website. It is the most complete qmail related site I've seen so far.

Concerning vpopmail, have you had a look to this fork? They have already added sqlite support and many other third parties patches (mine included) and improved a lot the program. I would like to use that version of vpopmail once they create a tag

Hi Roberto,

I wasn't aware of the vpopmail fork. I just checked their repo and they are on the right track.

Vpopmail is really a well-designed software, which we should all appreciate and not allow it to rot.

That was my main motivation to restore the abondoned vpopmail authentication support in dovecot, and I will try to contribute the new vpopmail fork as much as I can.

Great! Thanks a lot. I abandoned vqadmin years ago just when I switched everything to mysql, but now I'll give a chance again to it.

I'll certainly add this patch to my one. I'm also looking at your fixes to vpopmail.

Hi Mr Roberto,

i got this error message in my apache error.log file:

[Wed Sep 09 12:37:51.904875 2020]  /var/www/qmail/cgi-bin/vqadmin/.htaccess: Unknown Authz provider: valid-user

which area i need to look into?

thank you

did you enable mod_authz_user in your apache? look here https://serverfault.com/questions/737784/phpmyadmin-on-apache2-reload-unknown-authz-provider-valid-user-error

PS Can you take a look at the previous thread here?

Hi Mr Roberto,

thanks for the advise, it works now.

Hi Roberto

The following error occurred when apply the patch:

Hunk #1 FAILED at 32 (different line endings).
1 out of 1 hunk FAILED -- saving rejects to file html/mod_user.html.rej

It is found that files in source directory //html/ contain CTRL-M (^M) characters at the end of lines that lead to error when apply the patch.
You can run the command as underneath in that directory to remove the CTRL-M characters:

sed -i -e "s/\r//" //html/*

Afterthat, the patch can apply successfully without error.

Thank you, Tony. Corrected.

Hello Roberto

When I try to apply vQadmin patch, I got an error:

This new patch should be fine now...

Hello again,

try to download the source again and patch please, because I cleaned that file and uploaded it

Hi, there is a problem in my patch.

I'll fix it as soon as I can. In the meantime you can try to modify the file mod_user.html according to the html/mod_user.html.rej diff file, or compile as is, but the program will show the users' clear pwd.

Be aware that this program seems not work fine anymore. I don't remember what broke it at a certain point (perhaps it was the vpopmail upgrade to v. 5.4.33)

Be aware when using apache 2.4 with vqadmin will give the error "Authentication Failed Username unknown"

change your .htccess to

AuthType Basic
AuthBasicProvider file
AuthUserFile /var/www/cgi-bin/vqadmin/vqadmin.passwd
AuthName vQadmin
require valid-user

and the apache config to

ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
        AddHandler cgi-script .cgi .pl
        <Directory "/var/www/cgi-bin/vqadmin">
            Options ExecCGI
            AllowOverride All
            Require all denied
        
        Alias /images/ "/var/www/cgi-bin/vqadmin/images/"
        
            Require all granted

Thank you. It's working again now.

Actually it was sufficient ro remove

satisfy any

from .htaccess. Infact AuthBasicProvider defaults to file while the AddHandler option is already inside the httpd.conf

vQadmin cgi and virtual host file are not seen in browser - color ? - only seen when marked text

before adding password - /usr/local/etc/httpdpwd dir does not exists - must be created and chown apache.apache

> vQadmin cgi and virtual host file are not seen in browser - color ? - only seen when marked text

Thank you. This is another issue caused by the migration from the old drupal CMS

> before adding password - /usr/local/etc/httpdpwd dir does not exists - must be created and chown apache.apache

ok, I'm going to correct it

I followed your instructions,everything goes well,but when I access from web broswer by http://www.domain.com/cgi-bin/vqadmin/vqadmin.cgi

I get the following errors:

vQadmin was unable to determine your username, which means your webserver is improperly configured to run with this CGI. For security reasons, this script will not run without Apache htaccess lists.
 

Can you help me to solve this problem,many thanks.

supposing that you actually have apache configured in this way

Options ExecCGI
AllowOverride AuthConfig

did you modified, for some reason, the .acl and .htaccess files under the vqadmin dir?

in my vhosts.conf file,I added the following code,just copied from your instructions:

       # VQADMIN
        <Directory "/www/htdocs/qmail/cgi-bin/vqadmin">
            deny from all
            Options ExecCGI
            AllowOverride AuthConfig
            Order deny,allow 
        </Directory>

        Alias /images/ "/www/htdocs/qmail/cgi-bin/vqadmin/images/"
        <Directory /www/htdocs/qmail/cgi-bin/vqadmin/images>
            Order allow,deny
            Allow from all
        </Directory>

my .htacces in /www/htdocs/qmail/cgi-bin/vqadmin:

AuthType Basic
AuthUserFile /usr/local/etc/httpdpwd/vqadmin.passwd
AuthName "Authentication required"
require valid-user
satisfy any

what about the .acl file? I would try to restore it as the original. Double check  /usr/local/etc/httpdpwd/vqadmin.passwd as well

i used the default vqadmin.acl,and didn't edit it ,just the original file:

#

# Default group contains permissions for all users
# not listed under any groups
#
# If the default group is not defined, users not
# listed under any other groups will have no
# permissions.
#
# Examples follow...
#

default - ...

#
# Access permissions:
#M Modify user information

# U Modify domain information
# C Create user
# A Create domain
# D Delete user
# X Delete domain
#
# These features will still appear in the HTML templates
# if the user doesn't have access to them, however, they will
# get a permission denied error if they try to make use of
# them.
#

tech VI tech1user
admin VIMUDCA admin1user

#
# An asterisk in the features field specifies that you
# want all users in this group to have access to
# all features.
#

senior * admin

your vqadmin seems ok, but deeper investigation is needed also in your apache. Let me know if you solve

I have not solve this problem,but there's another more important problem.When I enable CHKUSER by:

# This enables chkuser
export CHKUSER_START=ALWAYS

I can just send email,but I can't receive email,and if diabled it ,everthing is ok,I don't know why?

It's not easy to troubleshoot without details, but If you are strictly following my guide feel free to contact me in private; in that case post your tcp.smtp and run files

Hi,

Is it possible to use the "ln" command instead of "cp -p"?

I am worried about maintenance when upgrading vqadmin.

Thanks,

I think that's even better
