The system crashed when I tried to open an xterm but not an hour ago.
I'm running ext3 and imho if there were messages they should have found
their way onto the hd, shouldn't they?

Well that was really a bad idea, but as long as the name of my computer
is listed in the news header (nntp-posting-host) people will have an
address to connect to. So should I manipulate my header so that it will
show something else?

So all comments about how secure openssh2.9.9p2-74 is are nonsense?

I used YOU to get the most (what SuSE calls it) up-to-date packages.
Whenever I update an rpm-package manually, I use the -u option.
Hopefully, YOU does the same...

Yes, that's clear. I first checked openssh.rpm as the sshd is part of
this package.

Is it a question of paranoia? Are there no ways to ensure that the
system is clean while keeping it alive? In evidence.txt they checked
the md5sums of the installed packages. Which database do they use as
reference? When I check all binaries as recently described, there is
still the possibility, that the rpm-database is corrupted itself, isn't
it? Or is the result, that the md5sums of all the binaries were ok
sufficient to declare this system being clean?
