But how can I determine that this is found in the epel repository and in general, how do I determine where the contribs repository is for packages I manage to find?
Here are popular repos for SME server.
https://wiki.contribs.org/Category:Yum_RepositoryYou can configure these on your server (with status disabled), & search them directly for packages
ONLY install packages by using the commend line switch --enablerepo=reponame
eg
yum --enablerepo=epel install packagename
If you want unusual packages, you will have to search for them manually,
eg by using rpmfind as Charlie has suggested
If you configure & search the popular repos like epel, dag & remi first you may well find what you want.
ie
yum list available --enablerepo=epel
yum list available --enablerepo=epel packagename
eg
yum list available --enablerepo=epel zmap
You can use yum commands/switches
eg
yum list installed Lists all packages that are installed on your system.
yum list available Lists all packages that are available to be installed in all enabled repositories.
yum search string Searches the package descriptions for the specified string.
