安装zlib
./configure --prefix=/usr --shared
make
make check
make install
cd /usr/local/src
wget http://www.openssl.org/source/openssl-0.9.8.tar.gz
tar xzvf openssl-0.9.8.tar.gz
cd openssl-0.9.8
./config --prefix=/usr/local/openssl-0.9.8
vi Makefile，修改mandir的内容，改为/usr/share/man
make
make test
make install
升级OpenSSH（依照最新的OpenSSL）
cd /usr/local/src
wget http://gulus.usherbrooke.ca/pub/appl/ssh/OpenSSH/portable/openssh-4.1p1.tar.gz
tar xzvf openssh-4.1p1.tar.gz
cd openssh-4.1p1
./configure --prefix=/usr --sysconfdir=/etc/ssh --with-pam --with-zlib --with-ssl-dir=/usr/local/openssl-0.9.8 --with-md5-passwords --mandir=/usr/share/man
make
make install
OK，现在ssh -V看一下版本吧
