Hi
I'm actually building a web interface to a news group server (INN).
One of the feature is to allow a few users to create and delete newsgroups
from the web. Basically, using CGI.pm, I retrieve the newsgroup's name,
whether the user ask for a creation or a deletion of a newsgroup, and
launch a few commands.
Normally, from the shell, I would perform the following operations to
create or remove a newsgroup (I will setuid the ctlinnd because ctlinnd
needs to be executed as the "news" user):
/usr/local/news/bin/ctlinnd pause "modification of active file"
/usr/local/news/bin/ctlinnd rmgroup/newgroup name_of_the_newsgroup
/usr/local/news/bin/ctlinnd reload active "reload active file"
/usr/local/news/bin/ctlinnd go "modification of active file"
If the server successfully performed the command, ctlinnd will exit with a
status of zero and print the reply on standard input. If the server could
not perform the command (for example, it was told to remove a newsgroup
that does not exist), it will direct ctlinnd to exit with a status of one.
It's not clear to me how I could retrieve the status code. I would also
like to know whether the way I use system() is right or if there is a
better way to do what I'm tryining to do.
You will find below the script on which I'm working
Have a nice day all
