Since Linux is all about choices we have provided as an alternative the commercial version of OpenSSH, The SSH2 and these installation instructions assume

Packages that you need can be downloaded from:

once you have got the Tarballs, It is a good idea to make a list of files on the system before you install ssh2, and one afterwards, and then compare them using diff to find out what file it placed where. Simply run find /* > SSH1 before and find /* > SSH2 after you install the software, and use diff SSH1 SSH2 > SSH-Installed to get a list of what changed.

Before you Compile, you need to decompress the tarball tar.gz.

           [root@deep] /#cp ssh-version.tar.gz /var/tmp
           [root@deep] /#cd /var/tmp
           [root@deep ]/tmp#tar xzpf ssh-version.tar.gz
           

You need to Compile and Optimize so move into the new SSH2 directory and type the following commands on your terminal:

           CC="egcs" \
           CFLAGS="-O9 -funroll-loops -ffast-math -malign-double -mcpu=pentiumpro -march=pentiumpro -fomit-frame-pointer -fno-exceptions" \
           ./configure \
           --prefix=/usr \
           --without-ssh-agent1-compat \
           --disable-suid-ssh-signer \
           --disable-tcp-port-forwarding \
           --disable-X11-forwarding \
           --enable-tcp-nodelay \
           --with-libwrap
           

This tells SSH2 to set itself up for this particular hardware setup as follows:

           [root@deep ]/ssh-2.0.13#make clean 
           [root@deep ]/ssh-2.0.13# make 
           [root@deep ]/ssh-2.0.13# make install 
           [root@deep ]/ssh-2.0.13#rm -f  /usr/bin/ssh-askpass
           

Please don't forget to cleanup after work:

           [root@deep] /#cd /var/tmp
           [root@deep ]/tmp#rm -rf ssh-version/ ssh-version.tar.gz
           

The rm command as used above will remove all the source files we have used to compile and install SSH2. It will also remove the SSH2 compressed archive from the /var/tmp directory.
