Linux за българи: Форуми

а на самата директория /home/user/public_html/all/html/ дали имаш правилните пермишъни и може ли apache-то да влезе вътре?

<?php
$output = shell_exec('/home/user/public_html/all/html/resetnet.sh');

намери реда, който започва с dip и добави след последното двуеточие www-data, ако вече имаш, а най-вероятно имаш потребител, го раздели със запетайка. трябва да изглежда така:

/usr/bin/poff: /bin/kill failed.  None stopped.
Error: only members of the 'dip' group can use this command.

Въпроса е дали да сменям "dip" на "www-data" или друг вариант?

dip:x:30:niki,www-data

dip:x:30:niki,www-data
защо намесвате www-data  ??? освен ако юзера apache не се казва www-data. поне в  редхатските дистота  httpd върви с името apache.

С какъв юзер ти върви apache-тo?

Не е точно така, искаш потребител, който няма право, да убие процес на друг потребител, затова ти се дъни.

я покажи командата pppd с какви правa е?


има лесен начин да правиш това през уеб сървъра, но не е много красив. Пишеш в 1 файл със скрипта, като примерно има само 0 или 1 във файла.
Пускаш един крон с root и проверяваш на всяка минута какво има във файла. Ако има 1, пускаш pon и poff и записваш 0. Ако пише 0, само exit. Собственик на файла е уеб сървъра... :)

cat 1 > /path/to/file
