Free powerful admin software for linux

Firewall Admin is not a firewall generator. This tool allows network administrators to manage iptables rules from anywhere though a simple administration interface through a Web browser. Any user can put some extra plug-ins to interact with netfilter modules.
Main features:
- View rules of Filter, NAT and Mangle tables
- Create and delete chains
- Create, replace and delete rules (filter, nat and mangle)
- Modules: tcp, udp, icmp, limit, mac, multiport, state, iprange, string, owner, comment, quota, mport, time, dscp, ecn, pktype, connmark and random
- Packets/bytes counter
- Rename userchains
- Mangle targets: TOS, MARK and DSCP
- Up and Down rules
- Change policy (ACCEPT and DROP)
- Flush chains
- Configuration
- Backup and Restore firewall rules and chains
Enhancements:
- fixed userchains targets to support no targets (default: ACCEPT)
- ruleoptions directory was removed (performance impact)
- support for patch-o-matic modules comment and quota
- support for native modules mport, time, string, dscp, ecn, pktype and connmark
- support for native modules random
- packages/bytes counter support

OpenVISP Admin project is a fork of Postfix Admin.
As administrator of a highly centralized and industrial grade hosting system, I need some webinterface to update data on a SQL database.
First I have used Postfix Admin to manage mail data but I was looking for more specialized system that is not a system that takes hours and is not configurable...
So I have started to modify Postfix Admin to suits my needs and so on.
Why OpenVISP Admin ?
I dont like 3 things on current Postfix Admin :
- The new license that has moved from MPL 1.1 to another proprietary one
- The bloody webforums and the fact that no authors was interested by my patches
- No CVS / CVSweb to see changes between versions
So this is basicaly why I have started a fork of Postfix Admin.
Main features:
- Quota enforcement
- Domain aliases
- Antivirus Checkbox when creating domain
- Antispam Checkbox when creating domain
- Sender / Domain verification checkboxes when creating domain
- GreyListing Checkbox when creating domain
- Spam Assassing Tag
- Spam Assassin Tag score value
- Tranport value when domain is backup MX
- Be more user friendly eg one login password with rights to get what he is allowed to
- Allow Postmasters to get access to APC Masterswitch
- To be done :
- Adding mod_vhs option for FTP and Web servicing purposes
- Allow postmaster to modify per aliases and per mailboxes SA values, etc..
- Allow user to modify their SA values on their mailboxes but also on their aliases
- Allow users to see their weblogs
- Allow users to search in logs for rejected messages and the reason why
- Redesign auth system to be more flexible.
How will this works ?
Interface
All the web interface will store data into MySQL (or PostgreSQL but this is not tested, I need some testers for that). The data is replicated and interfaced to a LDAP with a back_perl.
OpenLDAP back_perl
The back_perl scripts will be released when OpenVISP Admin 1.0 will be released.
Enhancements:
- The setup of all directories has been changed to be more clear about docs and contrib.
- lmtpd filtering options have been added.
- There is a new module to handle Web and FTP hosting.
- Some parts of the Web interface have been changed.
- More security checks have been added.
- There are many other new features.

ARAs goal is to create simple but convenient solution for managing the FreeRADIUS server.
ARA is PHP web-app operating on FreeRADIUS storage (currently only MySQL database). Look on its overview and decide is it right tool for you.
Enhancements:
- Visual polishing and end-user experience improvements.
- An easy system to integrate RADIUS users private information.

GRUB Web Admin module allows webmin (a web-based interface for system administration for Unix) to manage the grub bootloader.

Kiosk Admin Tool is a Point&Click tool for system administrators to enable KDEs KIOSK features or otherwise preconfigure KDE for groups of users.
Enhancements:
- Fixed lookup of UNIX-groups in kiosktool-kdedirs
- Removed "Lock down system wide Desktop icons", it was not implemented
- Removed duplicate "Disable Menu Editing" entry

Aw::Admin is a Perl extension for the ActiveWorks C Administration Libraries.

SYNOPSIS

use Aw MyFavoriteBroker@my.host.net:6449;
require Aw::Admin::ServerClient;

my $desc = new Aw::ConnectionDescriptor;

my $server = new Aw::Admin::ServerClient ( "my.host.net:6449", $desc );
#
# fix new to use default host weve already set..
#

my @brokers = $server->getServerBrokers ( );

foreach ( @brokers ) {
print "Territory : $_->{territory_name}n";
print "Broker Host: $_->{broker_host}n";
print "Broker Name: $_->{broker_name}n";
print "Description: $_->{description}n";
}

IMAP::Admin is a Perl module for basic IMAP server administration.

SYNOPSIS

use IMAP::Admin;

$imap = IMAP::Admin->new(Server => name.of.server.com,
Login => login_of_imap_administrator,
Password => password_of_imap_adminstrator,
Port => port# (143 is default),
Separator => ".", # default is a period
CRAM => 1, # off by default, can be 0,1,2
SSL => 1, # off by default
# and any of the SSL_ options from IO::Socket::SSL
);

$err = $imap->create("user.bob");
if ($err != 0) {
print "$imap->{Error}n";
}
if ($err != 0) {
print $imap->error;
}
$err = $imap->create("user.bob", "green");
$err = $imap->delete("user.bob");
$err = $imap->h_delete("user.bob");

$err = $imap->subscribe("user.bob");
$err = $imap->unsubscribe("user.bob");

$err = $imap->rename("bboard", "newbboard");

@quota = $imap->get_quotaroot("user.bob");
@quota = $imap->get_quota("user.bob");
$err = $imap->set_quota("user.bob", 10000);

@acl = $imap->get_acl("user.bob");
%acl = $imap->get_acl("user.bob");
$err = $imap->set_acl("user.bob", "admin", "lrswipdca", "joe", "lrs");
$err = $imap->delete_acl("user.bob", "joe", "admin");

@list = $imap->list("user.bob");
@list = $imap->list("user.b*");

$imap->{Capability} # this contains the Capabilities reply from the IMAP server

$imap->close; # close open imap connection

IMAP::Admin provides basic IMAP server adminstration. It provides functions for creating and deleting mailboxes and setting various information such as quotas and access rights.

Its interface should, in theory, work with any RFC compliant IMAP server, but I currently have only tested it against Carnegie Mellon Universitys Cyrus IMAP and Mirapoints IMAP servers. It does a CAPABILITY check for specific extensions to see if they are supported.

Operationally it opens a socket connection to the IMAP server and logs in with the supplied login and password. You then can call any of the functions to perform their associated operation.

Separator on the new call is the hiearchical separator used by the imap server. It is defaulted to a period ("/" might be another popular one).

CRAM on the new call will attempt to use CRAM-MD5 as the login type of choice. A value of 0 means off, 1 means on, 2 means on with fallback to login. *Note* this options requires these perl modules: Digest::MD5, Digest::HMAC, MIME::Base64

SSL on the new call will attempt to make an SSL connection to the imap server. It does not fallback to a regular connection if it fails. It is off by default. IO::Socket::SSL requires a ca certificate, a client certificate, and a client private key. By default these are in current_directory/certs, respectively named ca-cert.pem, client-cert.pem, and client-key.pem. The location of this can be overridden by setting SSL_ca_file, SSL_cert_file, and SSL_key_file (youll probably want to also set SSL_ca_path).

I generated my ca cert and ca key with openssl: openssl req -x509 -newkey rsa:1024 -keyout ca-key.pem -out ca-cert.pem
I generated my client key and cert with openssl: openssl req -new -newkey rsa:1024 -keyout client-key.pem -out req.pem -nodes openssl x509 -CA ca-cert.pem -CAkey ca-key.pem -req -in req.pem -out client-cert.pem -addtrust clientAuth -days 600

Setting up SSL Cyrus IMAP v 2.x (completely unofficial, but it worked for me) add these to your /etc/imapd.conf (remember to change /usr/local/cyrus/tls to wherever yours is) tls_ca_path: /usr/local/cyrus/tls tls_ca_file: /usr/local/cyrus/tls/ca-cert.pem tls_key_file: /usr/local/cyrus/tls/serv-key.pem tls_cert_file: /usr/local/cyrus/tls/serv-cert.pem
For my server key I used a self signed certificate: openssl req -x509 -newkey rsa:1024 -keyout serv-key.pem -out serv-cert.pem -nodes -extensions usr_cert (in openssl.cnf I have nsCertType set to server)
I also added this to my /etc/cyrus.conf, it shouldnt strictly be necessary as clients that are RFC2595 compliant can issue a STARTTLS to initiate the secure layer, but currently IMAP::Admin doesnt issue this command (in SERVICES section): imap2 cmd="imapd -s" listen="simap" prefork=0
where simap in /etc/services is: simap 993/tcp # IMAP over SSL
