Openswan random failures

I have an annoying problem with my Openswan VPN server. When I connect from a Windows XP machine, from that point on, I can only connect with that machine (or perhaps other Windows XP machines as well). On the other hand, when I connect with a Windows 7 machine first, connecting from Windows XP is no longer possible. Read More »

Turkey cooking time

As a note to self for next year: We just had a 8 kg turkey for our Thanksgiving meal. Recipes on the internet said it needed 7 to 8 hours of cooking. However, we took it out after 5.5 hours, and it was even somewhat overcooked. It probably needed about 4.5-5 hours. Read More »

FreeIPA: Active Directory for Linux?

Note to self: explore FreeIPA. Someone on Serverfault suggested it and said it was what AD is for Windows. If it is, it would relieve me of LDAP hell. Too long for this blog post, but I spent about a week (or more) full-time to get an LDAP setup working, with all security measures in place. It involved diving into source code, discovering and reporting Ubuntu documentation bugs, etc. An experience I don't care to repeat. Read More »
