In order to ensure that your genugate CD-ROM really is genuine, there is the possibility to verify all installation packages. An experienced hacker might for example replace programs from the original CD with his own versions that would grant him access to the genugate or even your internal company networks through built-in backdoors.
On Unix systems, the integrity of the CD-ROM can be verified as described below:
md5 /cdrom/3.9/i386/*.tgz sha1 /cdrom/3.9/i386/*.tgz rmd160 /cdrom/3.9/i386/*.tgz
On some Linux systems (e.g. Debian), the corresponding commands for checksum creation are possibly named a little different: md5sum, sha1sum, ripemd160
On Windows systems, you can use the freely available File Checksum Integrity Verifier (FCIV) utility The free of charge and plattform independent tool Tool Jacksum (JAva ChecKSUM) is able to verify MD5, SH1 and RIPEMD-160 checksums.
