Solution to scp missing on Minimal RHEL6 Install

If you choose the minimal installation of Red Hat Enterprise Linux 6, you do indeed get a minimal install. It's so minimal that things like wget and scp are missing. It's pretty obvious that yum install wget will get you wget but if you want scp:

Red Hat Enterprise Linux 5 on Dell OptiPlex 990 Initial Impressions

I received a Dell OptiPlex 990 and installed RHEL5 on it. Some preliminary observations:

  • I wanted a RAID 1, so I reached for a trusty 3ware 8006-2LP, which is a 64-bit-capable SATA RAID PCI card that I typically run in a 32-bit PCI slot.

yum install gcc mod_ssl openssl-devel httpd-devel

Then you're ready:

curl -O http://www.pubcookie.org/downloads/pubcookie-3.3.4a.tar.gz

Error: Nothing to do

I went into RHN and enabled the repository:
