Ser2net

[patrikg]

Can you make a new netstat command to the both, from rasbian and picore.

So you can see now that ser2net LISTEN to ipv4 instead of ipv6, so you don't need
ipv6-netfilter-xxx.tcz any more.

@patrickg, yes I will remove ipv6 extension. Thanks for your hint

Now I'm on the way understand how uucp can be disabled on piCore in order to work as on Raspbian.

Does anybody have some hints about UUCP ?

Probably you need to look into ser2net's source, what it's doing with uucp. Or just use the -u option

He doing what is he doing and it doesn't matter at all. With Raspbian it is no need to add the -u option. So, i want to know why piCore has not the same behavior.
There is rights problem ? piCOre configuration problem ? ...

You may read little of this, to understand how the serial device locking feature working.

https://tldp.org/HOWTO/Serial-HOWTO-13.html

Is ser2net some deamon or application ?
You can test to strace if its a application, to see if the application tries to make some type of lock file, and can't create if because of lack of file rights.

Hi olivier.com
Before you built  ser2net , you had to build  gensio , right?
When you run  ./configure  for  gensio , include  --with-uucp-locking=no

Of course it matters. If you don't know what it's doing, how will you find out why the behavior differs?

You're asking us, but none of us know. We don't have the hw, and it seems none have ever used ser2net.

You are right Rich !
The thing I have missed is gensio part.
I'll give it a try.

Many many thanks for your help and your advice. It helped me so much.

Ok Sorry. I thought (but it is not right) that piCOre has these type of locking activated by default. Thank you for your answer and hints.

So I achieve my extension building with success and it is working like a charm.

I give a little walkthrough if some people want to build and use the ser2net extension with piCore (and specially with with piCorePlayer in order to control old DENON AVR)

I cant post the message so I add it in attachment.

I'll add this to the piCorePlayer projects documentation if you like? See https://docs.picoreplayer.org/projects/

Hum... Why not.

Please correct my obvious english fault.. As I am a french guy, my english is quite good..

Many thanks Greg.

Hi olivier.com
A couple of minor points:
You misspelled export:

Code: [Select]

xport CXXFLAGS="-O2 -pipe -fno-exceptions -fno-rtti -march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp"
I was under the (possibly mistaken) impression that  piCorePlayer  like  piCore  compiled 32 bit apps to be
armv6 compatible:

Code: [Select]

export CFLAGS="-O2 -pipe -march=native -mfpu=vfp"
export CXXFLAGS="-O2 -pipe -fno-exceptions -fno-rtti -march=native -mfpu=vfp"

[Greg Erskine]

Please confirm potential typos.

Code: [Select]

3.9 Add the ser2net conf file

sudo touch /etc/ser2net.conf
sudo echo protocol,src_ip,port_to_reach_onRpi:raw:0:/dev/ttyUSB0:9600 8DATABITS NONE 1STOPBIT >> ser2net.conf

Missing directory. Should be ">>/etc/ser2net.conf"

Code: [Select]

3.10 We have to tell piCorePlayer to save these setting for future reboots :

sudo echo /etc/ser2name.conf >> /opt/.filetool.lst

Extra / and ser2name should be ser2net. Should be "etc/ser2net.conf"
