Re: Offline Repository

Before I go mirror the Raspbian repository onto a USB thumb drive (128GB of course), can you share your /etc/apt/sources.list and /etc/apt/sources.list.d/raspi.list? Maybe I can help if needed, but I have no access to my Pi since April and won't get back to it until somewhere in November, when I'm ...

Wheezy and Jassie on a single HDD

I need a hand in the following project: Currently I have Wheezy on a 512 GiB HDD, including some rather difficult to rebuild packages like a postgres based CMS, software for a logic analyzer and so on. I'd like to install Jessie in parallel, so there are three tasks: (1) create a new partition for J...

Re: Any Saleae compatible packages?

*bump*

Some time passed and we have a new Raspbian image. Before I try it: Will PulseView compile with the repository packages? I estimate the answer is yes, but are there other Raspbian/PulseView-users out there?

Can anyone confirm this link...

Re: Raspberry Pi Arduino Wifi Communication

Likely Dougies idea is better suited to your application, but I'll still answer: I want, from the website, for you to be able to send the arduino a "Turn on or off the led" kind of thing (more complicated than that but essentially an on or off switch. And also occasionally a number argument. So thin...

Re: HDD spins down

If this drive always worked this way I haven't noticed. Used it for about 4 years in my laptop. But then Win7 frequently accesses the HDD.

Thank you, I'll look for that firmware and try to update the drive!

I've bought an external S-ATA2USB connected HDD (WD blue, 1TiB), replaced the disk by another WD blue 512GiB disk and connected it to the Pi as root device (did so to actually upgrade my laptop with a brand new HDD ;) ).

Re: postgresql not working after dist-upgrade

Were you syncing a large tree, and using rsync options such as -H, which chews up a lot of RAM? I was syncing the entire HDD for the first time, so yes, I guess there were quite large trees. However, I used it more or less the way it was recommended to me to make a backup (rsync -ax --exclude '/med...

Re: postgresql not working after dist-upgrade

So problem solved. You need to ensure postgresql can read the snakeoil certificates or you need to create a new certificate pair that are owned by the postgresql userid (better option). It should be able to read it: /etc/ssl/certs $ ls -l ssl-cert-snakeoil.pem -rw-r--r-- 1 root root 1009 Mär 20 17:...

Re: postgresql not working after dist-upgrade

No.

Code: Select all

ls: Öffnen von Verzeichnis private/ nicht möglich: Keine Berechtigung
(permission denied)

Would it be safe to add postgres to ssl-cert and to chmod g+r privat? Would it work?

Re: Backup system using Bash file

To give some feedback: I wasn't able to record the image file back to disk (win32diskimager), but dd'ing the HDD-image straight to that medium was successful, and thus I recommend not only to take backups, but to try them at least once to make sure nothing will be lost.

I guess it's normal to get some errors dd'ing a running system, hence the noerror parameter, right?
