I have a new install of Red Hat and I'm trying to do a "yum install tmux" but it is throwing a no package available error:
[root@PSCHQVP20017 ~]# yum install tmux
Loaded plugins: product-id, refresh-packagekit, rhnplugin, security, subscription-manager
This system is receiving updates from RHN Classic or RHN Satellite.
Setting up Install Process
No package tmux available.
Error: Nothing to do
It is a bad idea to install "unofficial" software, specially on "enterprise" distributions or any sort of machine with critical jobs. You are taking over the full responsibility of security (and other) fixes, and keeping it in synch with the rest of the system's software (libraries, configuration, security configuration, ...). Look for alternatives, check what your distribution might have to say on the particular package. They might be excluding it due to unsolvable problems of some sort, perhaps licensing (that might or not be a problem to you, as a final user or due to the legal situation in your jurisdiction) or even security problems.
