Finding depends

[John Meissner]

I have a program on Red Hat 7.3 called usernet that monitors network traffic. On another Linux box I don't have this. I copied the file over and it complained that it's dependent files were "such and such" I copied them and it the program worked. I can't remember what file I copied to make it work and I'd like to document this. is there a way to find out what a programs depends are?

Hi,

Try "ldd program"

It will give you all shared libraries that the program depends on.

Good luck.

If you ever want an update you'll need to figure out where it came from.

I've gone through my redhat machines, but not the CD's and found nothing.

If it by chance did come off an rpm file then you are in business.

On the machine that has it:

rpm -q usernet

If you get an answer, that means it came off of one of the install cd's or some other kind of rpm distribution site.

Find the rpm download it to the target machine, run rpm -i usernet.whatever and it will list the requirments for install.

I once played to copy files game with ssh one machine to another. I could not exchange public keys after that stupid trick and eventually redid the entire OS on the machine I'd jacked with.

So unless I have source to compile or rpm's I have learned my lesson concerning file copy binary installations.

Good luck. If you find rpms or source, let us know, sounds like an interesting utility.

I will look at tucows and download.com and let you know if I find anything.

hi,
since you are having redhat and assuming that you have installed from the rpms rather than compiling from sources, the easiest way to find out where this binary came from is as below.

rpm -q --whatprovides

and regarding this usernet program, here is the info.
+++++++++++++
$rpm -q --whatprovides /usr/bin/usernet
rp3-1.1.4-4

$ rpm -qi rp3

Hope this helps. And I would suggest to install from rpm than copying files.
