Installing SuSE 11.2 or higher: before the first reboot the CLI version of YaST looks horrible. Reboot or second CLI fixes it.

Posted by jpluimers on 2013/08/19

Since SuSE 11.2, when installing then the CLI version of YaST looks horrible on the first (Ctrl-Alt-F1) console before you do your first reboot.

Workarounds:

  1. Try one of the other consoles,
  2. Reboot once.

It still fails at SuSE 12.x.

Getting a fresh root hint file on SUSE 12.x

Posted by jpluimers on 2013/07/31

Wrote a small script that goes into my monthly crontab.

It gets ftp://ftp.internic.net/domain/named.cache into /var/lib/named/named.cache.new, and logs when you need to copy it over into /var/lib/named/root.hint

ASUS RT N66U did not update DDNS with changed IP addres

Posted by jpluimers on 2013/06/11

Today my router had an IP-address change, but didn’t update the DynDNS.org information in my My Host Services | My Dyn Account. Which meant I could not “phone home”, as I didn’t know the new IP-address**.

Lesson re-learned:

During initial router configuration, watch the router logs, as you might have accidentally updated the DynDNS.org by hand, not by your router

Had this in the ASUS Wireless Router RT-N66U – General Log:

Jun 11 08:01:53 notify_rc : restart_ddns
Jun 11 08:01:53 ddns: clear ddns cache file for server setting change
Jun 11 08:01:53 ddns update: connected to members.dyndns.org (204.13.248.111) on port 80.
Jun 11 08:01:53 ddns update: server output: HTTP/1.1 200 OK^M Date: Tue, 11 Jun 2013 06:01:53 GMT^M Server: Apache^M X-UpdateCode: X^M Content-Length: 7^M Connection: close^M ^M notfqdn
Jun 11 08:01:53 ddns update: malformed hostname: myhostname

The problem: hostname should not only be the name of the host, but the FQDN of the host. Read the rest of this entry »

openSUSE 12.x: “A plain `halt` will not shutdown the system properly.”

Posted by jpluimers on 2012/12/30

Just noticed that in openSUSE 12.x, A plain halt will not shutdown the system properly.
On my system, it would leave the screen as shown on the right:

Only halt -p works, none of the other hints in the shutdown does not power off thread work, nor the acpi=off or acpi=oldboot settings.

The odd thing: a plain reboot still works properly.

If someone knows a better workaround: please let me know in the comments.

I hope they will fix this in a future openSUSE version; at least for 12.1 they have a “CHECKIT” marker in the documentation, but it has disappeared as of the 2.3 docs, but still fails:

5.4. systemd: System Shutdown

CHECKIT for 12.3. Is this entry still required?

To halt and poweroff the system when using systemd, issue halt -p or shutdown -h now on the command-line or use the shutdown button provided by your desktop environment.

Note: A plain halt will not shutdown the system properly.

Luckily, my openSUSE is a VM, which I can reboot from the ESXi host.
On a physical system, you will end up without any option to resurrect the system.

Later

After installing antivir, a plain halt works sort of: it says it is halted, but ESXi still thinks it is not:

After installing antivir, a plain halt works.

After installing antivir, a plain halt appears to work, but it doesn’t.

ESXi is sure the system didn't actually power down.
