register your RHEL client to Red Hat (after being reg'd to a Satellite)

Solution:  remove the up2date configuration, run rhn_register, then select the certificate at /usr/share/rhn/RHNS-CA-CERT

Issue:
When I first installed RHEL on my laptop I registered it to the Satellite I have at my house, behind a firewall.  I have a problem leaving my own Satellite exposed to the Internet as if someone found it, they could poach software off the thing whenever they like.  Normally having my laptop reg'd to my own Satellite is fine as I am home quite often.  However, today I had a need to install telnet and I am at my office.  I could open the firewall back to my house from the office, but I instead decided to register my laptop back to Red Hat since I have available entitlements.

# rpm -qa | grep rhn

# rpm -e rhn-org-trusted-ssl-cert-1.0-1.noarch
# cd /etc/sysconfig/rhn; mv up2date up2date.previous
# rhn_register

Then tell the app to use the cert located at /usr/share/rhn/RHNS-CA-CERT

RHN Satellite Server (spacewalk) repomd.xml not found

"repomd.xml not found" If you add a channel, or if your RHN cache gets corrupted, and one of your guests complains that it cannot find repomd.xml for jb-ews-2-x86_64-server-5-rpm (for example) - you need to rebuild your repodata cache. Normally this is an automated job - which is exemplified by the fact that you have obviously built out your entire Satellite environment and never had to do any of the steps you are about to do. So - some prep work: Open 3 terminals to your Satellite Server and run: # Term 1 cd /var/cache/rhn watch "ls -l | wc -l" # Term 2 pwd cd /var/log/rhn tail -f rhn_taskomatic_daemon.log # Term 3 satellite-sync --channel=jb-ews-2-x86_64-server-5-rpm Once the satellite-sync has completed, you >should< see the count increment by one.  If you are unlucky (like me) you will not. You then need to login to the Satellite WebUI as the satellite admin user. Click on the Admin tab (at the top) Task Schedules (on the left) fin

Install RHEL 7 on old HP DL380 g5

Someone at work had been running RHEL on an HP DL380 G5 and blew it up.  After several attempts at doing an installation that made me conclude the hardware was actually bad... I kept digging for the answer. Attempt install and Anaconda could not find any disks - try a Drivers Disk (dd.img) both cciss and hpsa.   -- once we did that, when the system would reboot it would say it could not find a disk. hmmm. Boot from your installation media and interrupt the startup at grub. Add hpsa.hpsa_allow_any=1 hpsa.hpsa_simple_mode=1 to the line starting with linuxefi press CTRL-X to boot. Once the system restarts after the install, you need to once again interrupt the startup and add the line from above. After the system starts, edit /etc/default/grub and add those 2 parameters to the end of the line starting with GRUB_CMDLINE_LINUX (which likely has quiet at the end of the line currently). then run # cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.orig # grub2-mkconfig -o /boot/grub2

MOTD with colors! (also applies to shell profiles)

I'm not sure why I had never looked into this before, but this evening I became obsessed with discovering how to present different colored text in the /etc/motd. A person had suggested creating a shell script (rather than using special editing modes in vi, or something) and I agree that is the simplest way of getting this accomplished quickly. This most noteworthy portion of this script is the following: RESET="\033[0m" that puts the users shell back to the original color. I typically like a green text on black background. Also - a great reference for the different colors and font-type (underscore, etc...) https://wiki.archlinux.org/index.php/Color_Bash_Prompt I found this example on the web and I wish I could recall where so that I could provide credit to that person. #!/bin/bash #define the filename to use as output motd="/etc/motd" # Collect useful information about your system # $USER is automatically defined HOSTNAME=`uname -n` KERNEL=`un
