[Arduino Library] Does WifiDriverInit() is missing in some package ?

[Olivier Burelli]

Hello all,

I would like to share my issue with the compilation of the sketch
provided by arduino.cc concerning the Wifi Whield.

After few try and some unrefferenced reference (IPAddress, WiFiDrv)...
as expected i edited the MAkefile:

LIBRARIES=SPI WiFi IPAddress WiFiDrv


Question:

as i still have an error message:

Did i miss something, something to do ?

Here, i am not sure to understand well, what happens, with avrdude or
avr-libc. 

Thanks in advance.

[Arduino] CLI serial monitor

[Olivier Burelli]

Hello,

i am playing with ARDUINO UNO on my 6.2 stable laptop.

I am trying to read the serial monitor message from the board.

from dmesg:
(...)
umodem0 at uhub3 port 1 configuration 1 interface 0 "Arduino SrlArduino Uno" 
rev 1.10/0.01 addr 3
umodem0: data interface 1, has no CM over data, has break
umodem0: status change notification available
ucom0 at umodem0

should i use cat /dev/DEVICE >> file.txt ?
or
(stty raw; cat > /home/me/received.txt) < /dev/device ?

--> which device is corresponding ?

does the information: "data interface 1, has no CM over data, has
break" means that OpenBSD can not receive data from the board ?

For example, i would like to catcg the strinf from the code below:
(...)
void setup(void) {
Serial.begin(9600);
// send the value of a string to the serial port (USB)
Serial.print("Hello world");
return;
}
(...)

Thanks in advance.

O.

Hello Mik J.

in first, sorry for my bad english.

Did you mix sysuser and user required to read the dedicated mount point for
virtual users (virtual mailboxes storage) ?

OpenBSD team provided the sysuser _dovecot to run the daemon.

I use on my side specific user also to read the Maildir folder in a specific
mount point : /var/vmail with user vmail
(vmail created manually : vmail:*:::Virtual
Mail:/var/vmail:/sbin/nologin)

Only the user vmail writes on the dedicated mount point for all virtual
mailboxes.
Dovecot is running with _dovecot sys account.

May i suggest you to read in parallel : http://wiki.dovecot.org/HowTo

Mainly the section userdb configuration, where you declare the user required
to read & write the virtuals mailboxes stored.

In my case i mixed sql authentication with static userdb part.

my dovecot -n :

# 2.2.21 (5345f22): /etc/dovecot/dovecot.conf
# OS: OpenBSD 5.9 amd64  ffs
first_valid_uid = 1000
listen = *
mail_gid = vmail
mail_location = maildir:/var/vmail/%d/%n/Maildir
mail_privileged_group = vmail
mail_uid = vmail
(...)
passdb {
  args = /etc/dovecot/dovecot-sql.conf.ext
  driver = sql
}
(...)
userdb {
  args = uid=vmail gid=vmail home=/var/vmail/%d/%n
  driver = static
}

the best way is to use : rcctl start || stop dovecot

previously you have to enable it on rc : rcctl enable dovecot

Seems that you followed intructions from 
/usr/local/share/doc/pkg-readmes/dovecot-2.2.21p0

For my configuration, informations below are ok.

+---
| Running dovecot-2.2.21p0 on OpenBSD
+---

By default, the _dovecot user, and so the Dovecot processes run in
the login(1) class of "daemon". The default limits on file descriptors
are insufficient to run Dovecot; instead you should put the _dovecot
user and processes in their own login(1) class with tuned resources.

For example, add this to the login.conf(5) file:

   dovecot:\
:openfiles-cur=512:\
:openfiles-max=2048:\
:tc=daemon:

Rebuild the login.conf.db file if necessary:

# [ -f /etc/login.conf.db ] && cap_mkdb /etc/login.conf
For larger servers these numbers and memory limits (e.g. datasize
and stacksize) may also need to be increased. In particular, indexing
emails for full-text search is likely to need an increased datasize.
Please report any changes and experiences to the package maintainers
so that we can update this file for future versions.

[httpd] rewrite url for PHP Framework (silex / symphony...)

[Olivier Burelli]

Hello all,

I am an end user that wants learn php, currently i try to follow a course.

For it i try to use httpd daemon on openbsd 5.9-stable

Sorry if this subject is posted yet in the past. In fact i do not really 
understood what about it is talked here : 
https://github.com/reyk/httpd/issues/27

So i understood from my followed course that i need the "rewrite-url" function.

Example for Apache : LoadModule rewrite_module modules/mod_rewrite.so
--> Goal (from the php course) : rewrite application url.

http://www.example.com/Tool/Calendar

instead of

http://www.downloadsite.com?app=34


Question : This functionality does exist with the httpd daemon ?


Thanks in advance.
