Do you know how I can install libc.so.6(GLIBC_2.3) on a 6.0.1
(which rpms and from where)
I do, but I'm not going to tell you, because you could easily break your system if you succeed in installing it.
I'm getting conflicts whith the ones I use.
Good thing to.
You haven't said why you want to install 'libc.so.6(GLIBC_2.3)'
on your system. My guess is because you are trying to install some software which is compiled for an incompatible system, perhaps Fedora Core.
If you find a RedHat 7.3 version of the software you are trying to install, you won't be told that you need libc.so.6(GLIBC_2.3). And the software will have a much greater chance of actually working after you install it.
