On this video I provide information about BMC and IPMI Configuration of LC Servers.

BMC ip adress configuration is tricky - done by ipmi lan commands.

petitboot configuration menu's do not affect it.

Not the best of days - so-called security PDF Print E-mail
Written by Michael Felt   

Yesterday my ISP turned me "off" because a certain "port" responded. They concluded - incorrectly - I was an open something (bot, relay - or who knows - they would not actually say - only hint).

Bottom line: my UDP port 123 was responsive - so I was evil.

Anyway, about 8 hours after receiving "special treatment" - things are back as they were.

Lesson learned: do not test NTP without first blocking UDP port 123 in  the "firewall".

Hard to be current! PDF Print E-mail
Written by Michael Felt   

Just saw a retweet - and followed it to see that IBM is being more serious about having opensource "more" current. But it is hard to be current - as I know from what I do on my own - for myself mainly. So, when I saw the IBM httpd package was newer than mine - I thought - time to get updated.

As an example, mine packaging is at level 2.4.20 and IBM's is at 2.4.23 - and the current level is 2.4.25. Hard to be current. Example 2: my curl is at 7.52.1(the current level) and IBM's is at 7.51.0. Again - Hard to be current.

A bit of maintenance - downtime explained PDF Print E-mail

You may have noticed a bit of downtime today - my apologies, but I needed to get some updates finally applied.

Soon I will write about configuring pop3ds and imapds - as this is something I have wanted to have working, but have always missed one or two bits. With the update I seem to have it configured so that it will work with TLS1.2 and not with SSLv3 or SSLv2. And, after a few more tests on some "undocumented" behaviors I will have a short blog on SecuringAIX and a longer tutorial on
