Free openvpn auth passwd 1.1 software for linux

OpenVPN Admin is a GUI for OpenVPN it is writen in Mono and runs under Linux and Windows.

Included in OpenVPN-Admin is a Certificate wizard and a certificate management for the client.

OpenVPN is a full-featured SSL VPN solution which can accomodate a wide range of configurations, including remote access, site-to-site VPNs, WiFi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls (articles) (examples) (security overview) (non-english languages).
OpenVPN implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or 2-factor authentication, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface. OpenVPN is not a web proxy and does not operate through a web browser.
For a good conceptual introduction to OpenVPN, see the program notes for James Yonans talk at Linux Fest Northwest 2004 -- Understanding the User-Space VPN: History, Conceptual Foundations, and Practical Usage. See also OpenVPN and the SSL VPN Revolution by Charlie Hosner.
OpenVPN is an Open Source project and is licensed under the GPL. Commercial licenses are also available for firms who would like to redistribute OpenVPN with their own proprietary applications. Contact info@openvpn.net for more information.
Main features:
- tunnel any IP subnetwork or virtual ethernet adapter over a single UDP or TCP port,
- configure a scalable, load-balanced VPN server farm using one or more machines which can handle thousands of dynamic connections from incoming VPN clients,
- use all of the encryption, authentication, and certification features of the OpenSSL library to protect your private network traffic as it transits the internet,
- use any cipher, key size, or HMAC digest (for datagram integrity checking) supported by the OpenSSL library,
- choose between static-key based conventional encryption or certificate-based public key encryption,
- use static, pre-shared keys or TLS-based dynamic key exchange,
- use real-time adaptive link compression and traffic-shaping to manage link bandwidth utilization,
- tunnel networks whose public endpoints are dynamic such as DHCP or dial-in clients,
- tunnel networks through connection-oriented stateful firewalls without having to use explicit firewall rules,
- tunnel networks over NAT,
- create secure ethernet bridges using virtual tap devices, and
- control OpenVPN using a GUI on Windows or Mac OS X.

Passwd project is the Horde password changing application. While it has been released and is in production use at many sites, it is also under heavy development in an effort to expand and improve the module.

Right now, Passwd provides fairly complete support for changing passwords via Poppassd, LDAP, Unix expect scripts, the Unix smbpasswd command for SMB/CIFS passwords, Kolab, ADSI, Pine, Serv-U FTP, VMailMgr, vpopmail, and SQL passwords.

mod_auth_ora7 is an Oracle Authentication Module.

I wrote this module because currently there is no module to do this. You can do it with mod_perl and the DBI interfaces therein. However, compiling in a copy of Perl seems like a bit of an overkill just for a simple authentication routine such as this.

This Module is largely based on the mod_auth_msql module and as a result all of its copyright appears below. Im releasing this code under the same licensing agreements as is set forth above in the original Apache Group license.

For the most recent information on this module please look at: http://www.vecdev.com/mod_auth_ora7/

Credit is due to the following individuals for their work on the mod_auth_msql prior to my adaptation: Rob McCool, Brian Behlendorf, rst, and Dirk VanGulik

Quick Compilation Instructions:

Make the followin modifcations to the Configuration File:
In EXTRA_CFLAGS add: -DORACLE_HOME="$(ORACLE_HOME)"
Yes the s and "s stay
In EXTRA_LFLAGS add: -L$(ORACLE_HOME)/lib
In EXTRA_LIBS add: -lclient -lsqlnet -lncr -lsqlnet -lclient -lcommon -lgeneric -lsqlnet -lncr -lsqlnet -lclient -lcommon -lgeneric -lepc -lnlsrtl3 -lc3v6 -lcore3 -lnlsrtl3 -lcore3 -lnlsrtl3 -lsocket -lnsl -lm -ldl -lc -laio -lposix4 -lm -lcore3

Yes there are dupilicates in there... dont ask me why it just doesnt work unless they are there, be sure that this is all on one line and that they are in the same order Ive given them to you.

In EXTRA_INCLUDES add: -I$(ORACLE_HOME)/rdbms/demo
Add a line that says: Module ora7_auth_module mod_auth_ora7.o
This can go just about anywhere but right around the other auth modules is a good idea.
Ensure that you have the ORACLE_HOME enviornment variable set properly!
Run the Configure script.
Run make

No guarantee that this will work... Ive only tested this personally on my machine, however many of the decisions as far as where to grab things were matched with DBD::Oracle of the Perl variety. So Im hoping this will be somewhat universal. FYI: My development platform was Solaris 2.6 X86, Oracle 7.3.2.3, Apache 1.2.4, and gcc 2.7.2.3... All other platforms are at your own risk.

Outline:

This module allows access control using the commercial Oracle7 database.

An example table could be:

create table user_records (
user_id varchar2(32) primary key,
passwd varchar2(32),
grp varchar2(32)
);

The user_id can be as long as desired; however some of the popular web browsers truncate, or stop the user from entering names longer than 32 characters. Furthermore the crypt function on your platform might impose further limits. Also use of the require users uid [uid..] directive in the access.conf file, where the user ids are separated by spaces can possibly prohibit the use of spaces in your user-names. Also, not the MAX_FIELD_LEN define somewhere below.

To use the above, the following example could be in your access.conf file. Also there is a more elaborate description afther this example.

Webmin OpenVpm Admin Module allows you to create static or CA-based VPNs through a Web interface.
Webmin is a valid web-based instrument for Linux/Unix system administrator. OpenVPN allows to create and manage VPN supplying wide possibilities of configuration.
Their union, with also the pressing necessity of having an efficient instruments of administration, has carried OPEN IT to develop a module of Webmin for OpenVPN.
The Open VPNadmin module is web-based and it can be used within Webmin. Witj this module you can:
- manage the Certificate Authority (CA)
- manage the VPNs and check the active connections
Enhancements:
- The device number (tun0, tun1, etc.) is automatically added and can be modified interactively.
- In the module configuration area the default server has been added as a new item.
- Tests for the validity of keys, servers, and clients were modified.
- New config files were provided for NetBSD and OpenBSD.
- The server static form was adapted to the Webmin skins.

CB3ROB Identd is an identd implementing the auth (RFC1413) protocol for use on public Unix machines. Unlike with other ident daemons, the AUTH protocol replies from this daemon cannot be spoofed by users.

CB3ROB Identd project has been optimized to handle as many requests as possible, and has been tested to work on most Linux distributions without modification.

Installation:

- become root
- unpack the files ("tar -xvzf cb3rob-identd-1.2.tgz")
- chdir to the cb3rob-identd directory ("cd cb3rob-identd")
- type "make install"
- add the service to your inet daemon (inetd or xinetd) config file
- restart inetd or xinetd

mod_auth_pam is an authentication module for the Apache Web-Server.

The PAM authentication module implements Basic authentication on top of the Pluggable Authentication Module library.

Thereby it supports standard unix passwd, shadow, NIS, SMB auth and radius (-> complete list of modules) authentication transparently and easily interchangeable, wherever the HTTP protocol allows it.
