  • AIXchange: Restricting FTP Access (AIX) – A customer was trying to restrict user access to a particular directory on an AIX system when FTP was used. We came across two good options.
  • FBI Tor Malware Analysis – [...] In April 2013, a piece of malware was found embedded in Freedom Hosting's darknet server that would exploit a security hole in a particular web browser and execute code on the user's computer. This code gathered some information about the user and sent it to a server in Virginia and then crashed – it had no obvious malicious intent that is so characteristic of malware. It was therefore theorised that the FBI, who have offices in Virginia, and who have 'form' for writing malware, may have authored it – this now appears to be true. [...]
  • Samba4 and OpenChange on a Debian or Ubuntu server – Samba4/Openchange suite promises to provide a complete Active Directory© domain controller with an alternative to a Microsoft Exchange server.

  • Sendmail relay configuration on AIX | Leave No Bit Unturned – This document describes how to set up a Sendmail e-mail gateway or relay which will be able to process incoming mail and route it to different mail servers based on domain information. The routing table is based on the Sendmail mailertable feature instead of the usual MX record based routing. This will come handy when there is a need to route mail internally in a different way than externally.
