I work at a place that locks down their servers, no way to use IBM when installing software.  So I downloaded the Toolbox iso ESD-Toolbox_for_Linux_Apps_Common_7.2-7.3_122024_LCD4107740.iso.  All the rpms I am  looking for are there.  I have tried to create a lpp_source, which works kind of, it used the ppc directory, but the rpms I really need are in the directory ppc-7.2 or ppc-7.3.  I also have tried yum, or rpm with them and they both say not the right format.  If I use smit and point it at the rpms on that iso, it says not the right kind of file.  Has anyone done this?  I know a full installation iso is easy to set-up but this Toolbox iso is not in the standard format.  I have tried so many things, ready to give up, pack up my desk and forget about it.  I am hoping someone in this group knows what I am talking about and knows how to fix it!

Take a look at this and see if it helps. Let us know how you go. Thanks.
