Implementation Single Account Pdc Vpn Based on Ldap
IMPLEMENTATION SINGLE ACCOUNT PDC VPN BASED ON LDAP Gregorius Hendita Artha Kusuma Teknik Informatika, Fakultas Teknik Universitas Pancasila [email protected] Abstrak Data is an important for the company. Centralized data storage to facilitate users for accessing data in the company. Data will be stored centrally with PDC (Primary Domain Controller). Build communicate between head office and branch office requires high cost for each connection is not enough to ensure safety and security of data. Exchange data between head office and branch office should be kept confidential. VPN (Virtual Private Network) makes communication more efficient, not only the cost affordable that connection, security and safety will be the primary facility of VPN (Virtual Private Network). Service were established in the system will be integrated using LDAP (Lightweight Directory Access Protocol) to create a single account in each services such as PDC (Primary Domain Controller) and VPN (Virtual Private Network). The purposes of this final project to design and implementation a system centralized data storage and build communicate between head office and branch office are integrated with LDAP (Lighweight Active Directory Protocol). Hopefully this system can give more advantage to each network users. Keyword: PDC, VPN, LDAP, Single Account. I. Introduction previous workstations. To support the performance of the employees of the company of course has a Centralized data storage makes it easy for users variety of network services are formed in it such as to access data. many companies need a ftp, mail server, file sharing etc. These services of centralized storage system, because the data is course have their respective accounts. -

Active-Active Firewall Cluster Support in Openbsd
Active-Active Firewall Cluster Support in OpenBSD David Gwynne School of Information Technology and Electrical Engineering, University of Queensland Submitted for the degree of Bachelor of Information Technology COMP4000 Special Topics Industry Project February 2009 to leese, who puts up with this stuff ii Acknowledgements I would like to thank Peter Sutton for allowing me the opportunity to do this work as part of my studies at the University of Queensland. A huge thanks must go to Ryan McBride for answering all my questions about pf and pfsync in general, and for the many hours working with me on this problem and helping me test and debug the code. Thanks also go to Theo de Raadt, Claudio Jeker, Henning Brauer, and everyone else at the OpenBSD network hackathons who helped me through this. iii Abstract The OpenBSD UNIX-like operating system has developed several technologies that make it useful in the role of an IP router and packet filtering firewall. These technologies include support for several standard routing protocols such as BGP and OSPF, a high performance stateful IP packet filter called pf, shared IP address and fail-over support with CARP (Common Address Redundancy Protocol), and a protocol called pfsync for synchronisation of the firewalls state with firewalls over a network link. These technologies together allow the deployment of two or more computers to provide redundant and highly available routers on a network. However, when performing stateful filtering of the TCP protocol with pf, the routers must be configured in an active-passive configuration due to the current semantics of pfsync. -
