Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

How to tell the hardware you have

I have Dell machines spread out all over. They are all running some version of Red Hat Enterprise Linux. Some a small number of RHEL 4, a few more RHEL 5, but the majority RHEL 6. Many times I spend a lot of time configuring and compiling software on one machine, only to have to do it on another. I am not familair enough with the machines to know if something is compiled on one machine, that it will work on another. What I would like to do is to run something on a machine that gives me confidence that and executable and libraries compiled on machine A, can run on Machine B. Outside of looking at the kernel and RH-Release, what else can I check.

hwinfo or lshw or dmesg would be good starting points. Take a look at the link below for other options: I don't use Red Hat so can't test.

In your case, you are SOL i suppose. You WILL have to compile for each version of RHEL AT LEAST - this is if you are lucky and all say RHEL 5 machines have the same libraries that you will need. And if you arent and you have different versions of libs you might have to compile multiple versions for the same OS.
By large, the hardware only counts in this case if you have to compile drivers for them, otherwise (drivers are available in the kernel) you will only have issues with supporting library versions (such as libc).

BTW a simple command is
lspci -v
or just
To see the components.

PS If you have lots of work you should try to devise some plan to bring every machine to the same OS level.

We are trying to move to all RHEL 6

Much of what I have had to install, over, and over again is listed below. For the most part I have spent many hours compiling and installing HDF4 and HDF5, along with NetCDF. I am new at this job, so I am trying to be careful, but there has got to be a better way. We use something called Modules:

Modules is a big help because it allow one to unload and load different version of software. For example we use The Portland Group compilers and Intel as well, there is C and Fortran, 4 to 6 versions of each installed through our workplace. Someone will ask me for NetCDF compiled with the Intel compilers. This will result in both executables and libraries to be used. In a former job combinations of software, say different versions of Apache, were located on a central server and NFS mount across the network. I asked the question since different users have different hardware, but I am about to propose the NFS solution
