configparser (Python 3.7) found no section in regular config file
I don't get why this code won't work, I checked every detail in the doc. What can be wrong with my cnf file format?
File /home/julien/Workspace/BnsManager/data/.secret/.paris.cnf
[ldap]
admin_dn=Directory Manager
admin_password=superpassword
Permissions on .secret folder
ls -la .secret/
drwxrwxr-x 2 julien julien 4096 oct. 16 15:51 .
drwxrwxr-x 6 julien julien 4096 oct. 16 15:42 ..
-rw-rw-r-- 1 julien julien 60 oct. 17 08:48 .paris.cnf
File test.py
import configparser
p = '/home/julien/Workspace/BnsManager/data/.secret/.paris.cnf'
cp = configparser.ConfigParser()
cp.read(p)
print(cp.sections())
The ouput is [] but I expected it to be ['ldap']
Do you see what went wrong?
Try this to get the exception with explanation why the file is not read:
import configparser
p = '/home/julien/Workspace/BnsManager/data/.secret/.paris.cnf'
with open(p, 'r'):
print('file could be opened')
cp = configparser.ConfigParser()
cp.read(p)
print(cp.sections())

I would like to do a ssh connection to a remote host, execute a given command, and attach the standard streams (output, input, error) to the local process (sys.stdout, etc..) in an asynchronous/interactive way.
I can execute the first command and I can see the output, but if I try to run it again, there is no output because the streams are closed from the first execution.
See the example below:
import asyncio
import asyncssh
import sys
def run_command(command):
async def run():
async with asyncssh.connect(host='localhost') as ssh:
await ssh.run(
command=command,
stdout=sys.stdout,
stderr=sys.stderr,
stdin=sys.stdin
)
try:
asyncio.get_event_loop().run_until_complete(run())
except (OSError, asyncssh.Error) as exc:
sys.exit('SSH connection failed: ' + str(exc))
if __name__ == "__main__":
print(sys.stdout)
run_command("ls -la") # this one works fine
print(sys.stdout) # sys.stdout is already closed
run_command("ls -la") # this one won't print either
Output
$ python example.py
<_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>

What would be the best approach to attach the standard streams in order to communicate to the process ?

The file is not printed in stdout...I have tried both codecs (json and plain)
edit: actually it might be the case the file has been read only once; does this have to do with sincedb?
how do I force logstash to read it again? isn't start_position => beginning enough?
start_position is used the first time the file is read.
If you want to force logstash to read it again, you need to add in your file input plugin conf this parameter :
sincedb_path => "/dev/null"

I'm working with Yocto to create an embedded linux distribution for an ARM device (i.MX 6Quad Processors).
I've configured the list of desired locales with the variable:
IMAGE_LINGUAS = "de-de fr-fr en-gb en-gb.iso-8859-1 en-us en-us.iso-8859-1 zh-cn"
As result I've obtained a file systems that contains the following folders:

Which is the encoding of all non ISO-8859-1 locales? Can I assume that "en_GB" or "en_US" use the UTF-8 encoding?
I've tried to open the "LC_IDENTIFICATION" file, the result is:
Hc�������������cEnglish locale for the USAFree Software
Foundation,
Inc.http://www.gnu.org/software/libc/bug-glibc-locales#gnu.orgEnglishUSA1.02000-06-24en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000en_US:2000UTF-8
At the end of the file there is something that recalls "UTF-8". Is this enough to assume that the encoding is UTF-8?
How to check if a locale is UTF-8?
LC_IDENTIFICATION doesn't tell you much:
LC_IDENTIFICATION - this is not a user-visible category, it contains information about the locale itself and is rarely useful for users or developers (but is listed here for completeness sake).
You'd have to look at the complete set of files.
There appears to be no standard command-line utility for doing this, but there is a runtime call (added a little later than the original locale functions). Here is a sample program which illustrates the function nl_langinfo:
#include <stdio.h>
#include <locale.h>
#include <langinfo.h>
int
main(int argc, char **argv)
{
int n;
for (n = 1; n < argc; ++n) {
if (setlocale(LC_ALL, argv[n]) != 0) {
char *code = nl_langinfo(CODESET);
if (code != 0)
printf("%s ->%s\n", argv[n], code);
else
printf("?%s (nl_langinfo)\n", argv[n]);
} else {
printf("? %s (setlocale)\n", argv[n]);
}
}
return 0;
}
and some output, e.g., by foo $(locale -a):
aa_DJ ->ISO-8859-1
aa_DJ.iso88591 ->ISO-8859-1
aa_DJ.utf8 ->UTF-8
aa_ER ->UTF-8
aa_ER#saaho ->UTF-8
aa_ER.utf8 ->UTF-8
aa_ER.utf8#saaho ->UTF-8
aa_ET ->UTF-8
aa_ET.utf8 ->UTF-8
af_ZA ->ISO-8859-1
af_ZA.iso88591 ->ISO-8859-1
af_ZA.utf8 ->UTF-8
am_ET ->UTF-8
am_ET.utf8 ->UTF-8
an_ES ->ISO-8859-15
an_ES.iso885915 ->ISO-8859-15
an_ES.utf8 ->UTF-8
ar_AE ->ISO-8859-6
ar_AE.iso88596 ->ISO-8859-6
ar_AE.utf8 ->UTF-8
ar_BH ->ISO-8859-6
ar_BH.iso88596 ->ISO-8859-6
The directory names you're referring to are often (but not required) to be the same as encoding names. That is the assumption made in the example program. There was a related question in How to get terminal's Character Encoding, but it has no useful answers. One is interesting though, since it asserts that
locale charmap
will give the locale encoding. According to the standard, that's not necessarily so:
The command locale charmap gives the name used in localedef -f
However, localedef attaches no special meaning to the name given in the -f option.
localedef has a different option -u which identifies the codeset, but locale (in the standard) mentions no method for displaying this information.
As usual, implementations may (or may not) treat unspecified features in different ways. The GNU C library's documentation differs in some respects from the standard (see locale and localedef), but offers no explicit options for showing the codeset name.
I try to build a short ocaml event example. But when I compile, the error in the title appears.
The question of: unbound module Event error when compiling Ocaml game was not helpful for me.
The system is Kubuntu 14.04 and I installed ocaml over aptitude, so installed packages are:
camlp4, ledit, libfindlib-ocaml, libfindlib-ocaml-dev, liboasis-ocaml, liboasis-ocaml-dev, libodn-ocaml, libodn-ocaml-dev, libtype-conv-camlp4-dev, oasis, ocaml, ocaml-base, ocaml-base-nox, ocaml-compiler-libs, ocaml-doc, ocaml-findlib, ocaml-interp, ocaml-native-compilers, ocaml-nox
The OCaml compiler is version 4.01.0
Here is my short test program.
open Thread;;
open Event;;
let chan = Event.new_channel();;
let a () =
Printf.printf "A waiting...\n";;
let sigRX = Event.receive chan in
Printf.printf "A received over channel\n";
let v = Event.sync sigRx in
Printf.printf "A running\n";
Printf.printf "A done!\n";;
let b () =
Thread.delay 0.8
Printf.printf "B sending...\n";;
let sigTX = Event.send "wake up" in
Event.sync sigTX;
Printf.printf "B done!\n";;
let t_a = Thread.create a ();;
let t_b = Thread.create b ();;
I tried to compile this single file (test.ml) with:
ocamlc -thread unix.cma threads.cma test.ml
The response is:
File "test.ml", line 2, characters 0-10:
Error: Unbound module Event
I googled, found some "thread-using-tips" like: http://caml.inria.fr/pub/docs/manual-ocaml/libthreads.html#c%3Athreads
In /usr/lib/ocaml is an threads folder and an thread.mli. Inside the threads folder there are this files:
-rw-r--r-- 1 root root 487 Jan 2 2014 condition.cmi
-rw-r--r-- 1 root root 487 Jan 2 2014 condition.cmx

-rw-r--r-- 1 root root 4145 Jan 2 2014 threadUnix.cmi
-rw-r--r-- 1 root root 1515 Jan 2 2014 threadUnix.cmx
What am I missing? I assume, that the Event is packed in Thread Module?
This command line works for me to get past the unbound module problem.
$ ocamlc -I +threads -c test.ml
There are errors in your code, but I imagine you'll know how to fix them.
This full command line will probably work, but I can't be sure because of the errors:
$ ocamlc -thread -I +threads unix.cma threads.cma test.ml
(There are some higher-level tools for building OCaml programs that you might want to learn about at some point.)
I want to forward an SMS using gammu-smsd RunOnReceive.
That is the script I want to run (/var/spool/gammu/forward.sh) and it goes perfectly if I run it from a sudoer or using sudo -u gammu -g gammu /var/spool/gammu/forward.sh
#!/bin/bash
SMS_MESSAGES=1

do
number="SMS_${i}_NUMBER"
text="SMS_${i}_TEXT"
eval "gammu-smsd-inject TEXT my_number_goes_here -text \"${!number}: ${!text}\""
done
And here is the problem I am experiencing:

Please, help
I had the same problem and I solved it this way:
First add gammu user to sudoers, with no password:
type: $ sudo visudo
and add: gammu ALL=(ALL) NOPASSWD: ALL
Then run gammu-smsd as root user:
in /etc/init.d/gammu-smsd
change USER=gammu to USER=root
save it and don't forget to restart daemon: service gammu-smsd restart
In RunOnReceive script add sudo in front of gammu-smsd-inject:
e.g.: sudo gammu-smsd-inject TEXT my_tel_num -text "Hello world!"
I hope this will work for you too!
P.S.: I use Gammu version 1.31.90.
