How To Set Up A Web-Based Enterprise Password Manager Protected By Two-Factor Authentication
Author: nowen • Tags: linux, security • Comments: 1How To Set Up A Web-Based Enterprise Password Manager Protected By Two-Factor Authentication While it is great that more services such as Facebook and Google are offering two-factor authentication, there are still plenty of services that do not. What is the next best thing? Using a password manager and incredibly complex passwords. A password manager allows you to use different passwords at all the sites and services you visit, but it creates a 'keys-to-the-kingdom' problem. This tutorial will show you how to install the WebKeePass open-source web-based, enterprise password manager and how to protect it with two-factor authentication from WiKID Systems. Note that we have not evaluated the security of WebKeePass - this would certainly be worthwhile. Our primary selection criteria were: open-source, multi-user and allowed for external authentication, in this case via LDAP. Another option that looked promising was CorporateVault.

Author: sftp • Tags: ftp, lighttpd, linux, samba, ubuntu, web server • Comments: 1
Ubuntu 10.10 LAN Torrent Seedbox With Avalanche-rt, Lighttpd, Rtorrent, Vsftpd And Samba This tutorial is based on a LAN setup, but it should also be applicable for an Internet seedbox (e.g. on a vps or rootds), but some additional steps may need to be performed (firewall, securing rpc-mount, generally hardening of the server). The best lightweight software combination for a seedbox is lighttpd with rtorrent/libtorrent and a nifty web interface. So we use avalanche-rt, an actively developed project which looks very promising.
