Verifying Solaris CD Downloads with md5 Checksum on Ubuntu
I didn't know weather to post this in the Solaris or Linux forum so move it if necessary.

In the Solaris 10 CD Download Instructions, it says:
Quote:
Once you have downloaded a file, you should check that it has not been corrupted during the download before burning it to a CD.
For that, you need to do an "md5 checksum", which compares your downloaded file against the file you would find on the server.
I open up a Terminal (I'm running Ubuntu Linux) and do a man on md5. It gives me this syntax:
Code:
SYNOPSIS
       openssl dgst [-md5|-md4|-md2|-sha1|-sha|-mdc2|-ripemd160|-dss1] [-c]
       [-d] [-hex] [-binary] [-out filename] [-sign filename] [-passin arg]
       [-verify filename] [-prverify filename] [-signature filename] [file...]

So I run it on all the zip files I downloaded and the iso files I extracted from them:
Code:
brad@rockstar:~/Solaris 10 5-09$ openssl dgst -md5 sol-10-u7-ga-x86-v1.iso sol-10-u7-ga-x86-v1-iso.zip sol-10-u7-ga-x86-v2.iso sol-10-u7-ga-x86-v2-iso.zip sol-10-u7-ga-x86-v3.iso sol-10-u7-ga-x86-v3-iso.zip 
sol-10-u7-ga-x86-v4.iso sol-10-u7-ga-x86-v4-iso.zip sol-10-u7-ga-x86-v5.iso sol-10-u7-ga-x86-v5-iso.zip
MD5(sol-10-u7-ga-x86-v1.iso)= 936ae7424f9e4e502b0c5afb31c76fab
MD5(sol-10-u7-ga-x86-v1-iso.zip)= e9b7a2ddc2534ca34afae192f3257e25
MD5(sol-10-u7-ga-x86-v2.iso)= 23732a79c43531b9b983a806bca8c37c
MD5(sol-10-u7-ga-x86-v2-iso.zip)= 7aa8e8db4821d227a926ba95dd4ef223
MD5(sol-10-u7-ga-x86-v3.iso)= 512ac1b5a226f505782401e98a1a371e
MD5(sol-10-u7-ga-x86-v3-iso.zip)= 3a9897d23a9c3b3b4144010ca17625a8
MD5(sol-10-u7-ga-x86-v4.iso)= f99e845473c85eadff9c6fbba47ccd32
MD5(sol-10-u7-ga-x86-v4-iso.zip)= 539efa6291722c0ad2699a4ba10b146a
MD5(sol-10-u7-ga-x86-v5.iso)= 1bc93383264179ef43a0df17cb130259
MD5(sol-10-u7-ga-x86-v5-iso.zip)= 738aa51a976de67c8721d21f5f4ec7d6

All the strings that are outputted match the strings in the file I also downloaded from the same place as the zip files containing the Solaris iso images. Does this mean that it verified the files and I'm good to install?

If the md5 output matches what it says it started as - you are good to go.

For Example if you download the following ISO "sol-10-u7-ga-x86-dvd". The MD5 for this is "6e1fc99eee3cdb0e88b8322521fd60a3". If it match, you can Install normaly !!!!
