...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 defa...

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? > When PermitRootLogin is
