RE: sshd and RSA Authentication


Kim,

I have you looked in /usr/doc? Here's a list of files there:

bzip2-1.0.1.README      jbigkit-1.2.README      ncurses-5.2.README
vim-5.7.README
crypt.README            jpeg-6b.README          openssh-2.3.0p1.README
wget-1.6.README
cvs-1.11.0.README       libpng-1.0.9.README     perl-5.6.1.README
xpm-4.0.0.README
gdbm-1.8.0.README       login.README            readline-4.1.README
zip-2.3.README
gettext-0.10.35.README  mt.README               tiff-3.5.5.README
zlib-1.1.3.README
inetutils-1.3.2.README  ncftp-3.0.2.README      unzip-5.41.README

check out the files for login, inetutils, openssh to begin with. And if you
still have a problem. Search the mailing list:
