OpenSuSE Tumbleweed ntp problem after snapshot 20160905 will be fixed in snapshot 20160908

Posted by jpluimers on 2016/09/09

On some systems, after upgrading OpenSuSE Tumbleweed to 20160905 ntp stops working.

TL;DR

Pending the verification of snapshot 20160908 (not finished yet), if if you have updated to 20160905 or 20160907,, the bogus ntp version is, so you have to downgrade:

zypper in --oldpackage  http://download.opensuse.org/tumbleweed/repo/oss/suse/x86_64/ntp-4.2.8p8-1.3.x86_64.rpm
systemctl restart ntpd.service

Or wait a few hours and install snapshot 20160908.

I will never grow up. I will grow, not sure which direction, but not up.

Now I need someone who can make a nice cartoon out of this…

Modifying openssl to build on Mac without makedepend: using cc -M/gcc -M/clang -M

Posted by jpluimers on 2016/09/08

Coping with OpenSSL is frustrating on so many levels. It would be hilarious if not so many depended on it.

The main thing is that there is so much cruft in openssl but nobody seemingly to care enough about copying with that cruft. Though the intentions of the LibreSSL are great and it has far left cruft, it didn’t gain enough ground in the 2+ years it exists.

For me, the biggest problem was that OpenSSL would fail to build on “modern” OS X versions. These lack makedepend which was part of OS X, but got removed somewhere between 2006 and 8.0 in 2012. Luckily, the 2006 post also mentions the alternative: gcc -M.

Actually cc -M or clang -M work just as well as cc symlinks to clang and gcc calls clang with some parameters.

OpenSSL references makedepend in a lot of Makefiles (see list below). The good part is that config and Configure modify the Makefiles so most people use a manual workaround after running Configure or revert to a macports built or other binaries of makedepend or a homebrew formula.

That is not really an automated solution suitable for general use, let alone suitable for Continuous Integration, so I dug a bit deeper: config is a shell script and Configure is a sherl script: a cleverly crafted shell script starting with the below line invoking Perl with the rest of the script. The reason is that #! shebangs need an absolute location which for Perl can vary. A nice discussion on this trick is at Running Under Some Shell which contains a more elaborate how this works:

TUMBLEWEED Poor performance in VMware Fusion can be a `search localdomain` issue

Posted by jpluimers on 2016/09/07

I figured this out, it turned out to be a DNS resolution issue. For some reason leaving ‘search localdomain’ in resolv.conf generates some slowness. I’m not sure if it’s because 127.0.0.1 isn’t mapped to ‘localhost.localdomain’ in /etc/hosts by default, or whatever, but taking it out fixes the performance issue.

Need help with OpenSuSE Tumbleweed `cd:/content: Invalid signature. Installation aborted.`

Posted by jpluimers on 2016/09/07

This succeeded: https://openqa.opensuse.org/tests/overview?distri=opensuse&version=Tumbleweed&build=20160901&groupid=1 installing the image from http://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-DVD-x86_64-Current.iso.mirrorlist (for which the md5 and sha signatures match).

But I got this cd:/content: Invalid signature. Installation aborted. message:

After a few statements [WayBack] in the install shell:

mkdir /mnt/cd
mount /dev/cdrom /mnt/cd
cd /mnt/cd
gpg --import content.key
gpt --verify content.asc

Indeed the cd:/content didn’t verify as content.key wasn’t a trusted signature:

How to proceed?

“Yes/No” question with what kind of buttons? Indeed “Yes/Cancel” SourceTree for Windows installer – latest version.

Posted by jpluimers on 2016/09/07

Yes, people still do this: Screenshot 2016-09-07 15.59.24.png

This one is worse than the usual “Yes/No” questions missing one or more of the “Yes” or “No” buttons in that it actually mentions you can click “No”.

Load SSH Key?

Do you have an SSH kkey that you’d like to load now? If not you can click “No” and create one later if you like”.
