  • E-MailRelay — SMTP proxy and store-and-forward MTA – E-MailRelay is a simple SMTP proxy and store-and-forward message transfer agent (MTA). When running as a proxy all e-mail messages can be passed through a user-defined program, such as a spam filter, which can drop, re-address or edit messages as they pass through. When running as a store-and-forward MTA incoming messages are stored in a local spool directory, and then forwarded to the next SMTP server on request.

    Because of its functional simplicity E-MailRelay is easy to configure, often only requiring the address of the target SMTP server to be put on the command line.

    E-MailRelay can also run as a POP3 server. Messages received over SMTP can be automatically dropped into several independent POP3 mailboxes.

    C++ source code is available for Linux, FreeBSD, MacOS X etc, and Windows. Distribution is under the GNU General Public License V3.

  • OpenSource-IT.com – Finding the open source solutions ready for the enterprise
  • Ring of Saturn Internetworking – These documents and tools were created by me while I worked at Verio as well as all the time since then. As such, there are still some references to "customers" and maybe even some procedures we used while I worked there. Since the content is just fine, just a bit weird to read, I haven't updated these and am focusing more on adding new content rather than fixing these "bugs".

  • using mod_auth_kerb and Windows 2000/2003/2008R2 as KDC – This tutorial contains my knowledge about using Apache/mod_auh_kerb and Windows 2000/2003/2008R2 as KDC.
  • Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
  • active directory – Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP – Server Fault – This is setup with Squid 3.0, has also been tested with Squid 3.1 and should work with Squid 2.7. Your Windows user must be a member of the SQUID_USERS group in Active Directory (for this case anyway).

    On the Windows side, Windows XP and Windows 2007 have been tested against Windows 2008, and Windows XP against Windows 2003.

  • What is FreeIPA? – FreeIPA is an integrated security information management solution combining Linux (Fedora), 389 (formerly known as Fedora Directory Server), MIT Kerberos, NTP, DNS. It consists of a web interface and command-line administration tools.

  • FreeIPA and Samba 3 Integration – techslaves.org – FreeIPA makes a pretty excellent backend for Samba 3. While all the information one needs to set this up is available online, I wasn’t able to find it all  in one location so I’ve decided to try my best at filling that gap here on techslaves.org. Hopefully this short guide will aid those trying to piece together the various parts necessary to integrate FreeIPA v2 and Samba 3, at least until FreeIPA v3 where there is talk of enabling Samba integration with a simple command line argument to the “ipa-server-install” script.
  • Time Navigator HA Cluster Agent Configuration – techslaves.org – I’ve been wanting to post about a configuration that allows for seamless file-level backup of storage attached to an active/passive high availability cluster in an uninterrupted fashion using Atempo’s Time Navigator and I’m finally going to do it.

  • A TCP Proxy in Perl – good coders code, great reuse – Several weeks ago my friend Madars was in an airport in the Netherlands and he wanted to login into his server via ssh. It turned out that their public internet had only ports 80 and 443 open so he couldn't do that. He asked me if I could proxy either port 80 or 443 to his server. Surely, I had a solution. I modified the tcp proxy server that I had written for my Turn any Linux computer into SOCKS5 proxy in one command article and did:<br />
    sudo ./tcp-proxy2.pl 443 madars-server.com:22<br />

Roll up your sleeves, spit on your palms, and get ready to go to work because this is your crash course in actually using IPv6. It hardly hurts at all. Linux has supported it since the 2.1 kernel, so you shouldn't have to install anything. Make sure you have the ping6, ip, and ifconfig commands. […]
