Audit assistance software / Spyware
project rautor Δωρεάν πρόγραμμα καταγραφης της χρησης του υπολογιστή.
Windows Desktop screen irecording utility, or zero budget SOX/PCI-DSS compliance software aid. Peridically Saves the user's screen and at a later time the security administrator can use my rautor player to review / audit the session.
openssh-4.7p1-logging.diff Hack against openssh-4.7p1 to save all ssh transactions to typescript like files. Original hack from Koen De Vleeschwuuer of kdvelectronics.eu. My hack is prettier :-). Make ssh will fail , so first make the full project before applying the patch.
Project coliau Δωρεάν πρόγραμμα εξ'αποστάσεως εποπτείας του υπολογιστή

Open source Win32 Console/screen auditing aid. Run it on a PC, and then you can monitor its main display with just a remote web browser. Use a url like http://Monitored.PCs.IP:44000/monitor

Note: European communications law demands that the user whose screen is being monitored must be notified of the process, accordingly my software displays a big red dot on the user's SysTray to notify him/her of that.

Email Systems Software
LdapVfrom-milter A milter to verify/validate Sender addresses against an LDAP server
Postfix Virtual with LDAP My implementation of the perfect email server based on the Postifix LDAP drive Virtual mailboxes. A sample from the main.cf the modified qmail schema I used and the ldap lookup files. By using the MailTransport Ldap entry one can have a zero maintenance completely dynamic email server. And I like maildrop for filters and soft quota management.
Postmaster Admin A virtual domain postmaster's admin module written in PHP by John Belekios
OpenLdap Acls A slew of slapd's acls to permit anonymous bind from the MX server, and postmaster@domain control for the subtree that belogns to him. When the postmaster binds to the Ldap Server (s)he can see only his/her domain's emails and entries.
Mail account creator A two step commit implementation. This script lists all new accounts, applies quotas and reset's the account status to "active" when all is well.
email to oracle DB insertion An ancient program to be used for entering the subject of an email message into an oracle DB
Black/White and Q A qmail local delivery program that can enforce user defined black and white lists as well as apply quota management
Vpopmail to Ldap Convert VpopMail Databases to my LDAP schema.
Find (IN)Active email accounts This is a dynamic optin mechanism for sqlgrey, any account not used for 33 days gets inserted into sqlgrey's optin table. Great for reducing SPAM, and keeping active users happy.
exim2zimbra.bash Migrate exim's virtual settings to zimbra

php radacct A php based mysql accounting system for FreeRadius still pre-beta beta testing needed
php radius management Some usefull PHP scripts to manage a freeradius server and users
