What browser are you using? The connection to the ASMI port, when not using an HMC as proxy must be using so-called "low-grade" https (aka 40-bit encryption). This is a known issue with Power5, but was easy to get around with Firefox - until version 19 came out. FF, like IE, Omega and Chrome (the ones I have checked) have all removed support for 40-bit encryption. FF forums say it is for a better user interface (they were having troubles explaining low-grade encryption).
Actually, I was expecting to read that 40-bit was not safe enough to support - but they forget one premise of Security is Availability. And making something unavailable is also a security breach.
Anyway, I have resolved my issue by downloading FF 17.esr as this is going to be supported for a while (while v18 is not - that became v19).
Here is a link to
v17.esr
Better is perhaps a link to
all releases
Remember to turn off automatic updates, or like I, you will find yourself with a version that no longer supports 40-bit encryption. Also remember to check for updates - because with updates turned off, you will not be notified that there is a new update (as I just noticed, while writing this, that 17.esr has been updated).
OK - you have the browser - but it still is not working?
Last steps:
enter
about:config in the URL, and say yes (i.e.,
I'll be careful, I promise) to warning.
in the search bar type:
40_md5
This should give two values - by default both are
false. Toggle them to
true (they turn bold) and try to access your page again.
Hope this helps!
