HP-UX slow login problem found?
...my speeds were about 100 times
slower! The DH speed is much harder to measure, but it was definitely
real slow with the gcc compiled version.
Okay, what's going on inside the OpenSSL code.... there are two small
functions which are responsible for about 95% of the CPU clock cycles.
These are bn_mul_add_words() in the file crypto/bn/bn_asm.c and the
function BN_mod_word() in the file crypto/bn/bn_word.c. The first is
responsible for the miserable RSA speeds, and the later for the
horrible DH speeds. I'll discuss how to speed each of these up
separately.
The bn_mul_add_words() function is by defau...

Information leakage in sshd
Hi guys,
and here's a security related bug report. I think it's has been fixed in
the 2.2.x-release of openssh, but I'm not sure. I tried to reproduce the
problem with my 2.2.0p1 and could find any difference in the behaviour
of ssh depending on wether PermitRootLogin was set to no. Could someone
please confirm that this problem is not existing anymore?
