Re: Opensuse 64bit and rpi2/3?

OK, I'm on a 64bit official kernel with Raspbian now.

Uptime is 10min and no obsolete instruction warning in syslog.

~$ uname -a
Linux pi1 4.14.18-v8+ #1 SMP PREEMPT Thu Feb 15 22:40:27 CST 2018 aarch64 GNU/Linux

Re: Opensuse 64bit and rpi2/3?

I tried 64bit kernel on Raspbian. So a userland in 32bit might call "obsolute" instruction.

I think SUSE have a 64bit userland?

Someone said the GPU is in 32bit mode so currently don't work well with a 64bit kernel. Not sure about.

Rumour won't help after all. So I'll try a 64bit kernel myself.

Re: Advice requested for use as small file server

If you use a USB/Ethernet adapter you will get around 3 times that (my USB3 Anker adapter gives me 318MBsec measured with iperf). I'd stick with Raspbian Lite, even if you know Lubuntu better. A file server would receive data from the storage, then send them to Ethernet. So the throughput on Ethern...

Re: Opensuse 64bit and rpi2/3?

I compiled the official 4.14 kernel with Debian's ARM gcc yesterday. I hesitated if I should go the normal 32bit kernel or the 64bit kernel. I remember that when I did that before, the syslog would fill up with "application calling obsolete instruction, so trying emulating that". And the system woul...

Re: Advice requested for use as small file server

Raspberry Pi got 100MBits/s Ethernet, which is a bit slow for today, but could be adequate for a small server. I think it's strength is the support. There are guaranteed working software suites available, and a paid team working on it. And its forum is helpful. And Debian has a list of cheap server ...

Re: ラズパイをイーサネットコンバータにしたい

こんにちは

このイーサネットコンバータと言う言葉はよく分かりませんでしたが、DuckDuckGoで検索して見たところ、無線LANをイーサネットにつながるハードのことでしょうか?

私のシステムでは、無線インターフェースにhostapdと言うプログラムを動くさせ、それをイーサネットとbridgeで繋がって走っています。
つまり新規した無線LANをイーサネットに繋がっています。

しかし既存無線LANを既存イーサネットに繋がる方法は私にも分かりません。ルータ機能は必要と思いますが、実際に作ったことがないです。

Re: 追加したユーザーで音声を出力できない

こんにちは

音声再生のため、ユーザーがaudioグループに入る必要があります。「グループ」は「権限」の同義語と思ってます。
グループ追加コマンド:sudo adduser 「アカウント名」 「グループ名」
つまり sudo adduser 「新規さん」 audio
このコマンドは管理者権限が必要ので、新規ユーザーは実行できないかもしれない。piユーザーで実行すればいいと思います。

ほかのグループについての説明は、/usr/share/doc/base-passwd/users-and-groups.htmlを参照してください。

I think you only need PREROUTING for outside access. The nat table works differently than the default filter table. It only work on the very first packet of a connection. After that, there is an "NAT engine" would take care of the rest of the packets for the same connection: http://www.iptables.info...

According to https://wiki.debian.org/SSDOptimization

If you are planning on doing a huge amount of writes (more than 40-50 GB per day), it is advised to avoid SSDs that use TLC NAND.

Re: When will Raspberry Foundation admit that the Pi destroys your SD cards?

I think Google "raspberry pi destroy sd cards" is a bad idea, because Google is so capable that would even give you devil's whisper. You'll almost never feel alone when you ask Google.

How about Google "raspberry pi uptime" instead?
