[opensuse-programming] How to implement a utility to integrate a milter with sendmail?
by Alban Deniz 25 Feb '13

25 Feb '13

Hello, I'm developing a utility SNFMilterConfig that integrates an email milter (SNFMilter) with sendmail, and am having difficulty because the file /etc/mail/sendmail.mc doesn't exist on OpenSuse (i.e. isn't part of any package). I'd like to know whether there's a way to automatically integrate a milter with sendmail on OpenSuse. I'm working with OpenSuse 11.0, but would like to support current and recent versions of OpenSuse. I've learned that SuSEconfig is used to configure sendmail by reading /etc/sysconfig/sendmail and creating sendmail.cf from a temporary sendmail.mc file. Although /etc/sysconfig/sendmail is well-commented, I couldn't find any mention of milters. A google search of SuSEconfig turned up the "Unofficial SUSEFAQ" (sysefaq.sourceforge.net/faq/suseconfig.html), "SuSEconfig and /etc/sysconfig" (www.novell.com/documentation/suse91/suselinux-adminguide). These described SuSEconfig, but I couldn't find any info on configuring a milter. My search of the OpenSuse forums and help portal wasn't fruitful. SNFMilterConfig integrates the milter with postfix by modifying the /etc/postfix/main.cf file (which is part of the postfix package). Is there an analogous configuration file for sendmail that SNFMilterConfig can modify to integrate the milter? I'd appreciate any suggestions and references. Please also let me know if there is another more appropriate list for this issue.

[opensuse-programming] PyQt4: connect calls slot-method with some argument
by Alex Naumov 15 Feb '13

Hi, I'm trying to connect widget with my own method. Using such implementation I get success: self.action_wired = QAction(QIcon("images/wired.png"), Interface, self) self.trayMenu.addAction(self.action_wired) self.connect(self.action_wired, SIGNAL("triggered()"), self.wired) ... def wired(self): print hello but I want to call "self.wired" with parameter/argument. Such call is failed: self.connect(self.action_wired, SIGNAL("triggered()"), self.wired(Interface)) TypeError: arguments did not match any overloaded call: QObject.connect(QObject, SIGNAL(), QObject, SLOT(), Qt.ConnectionType=Qt.AutoConnection): argument 3 has unexpected type 'NoneType' QObject.connect(QObject, SIGNAL(), callable, Qt.ConnectionType=Qt.AutoConnection): argument 3 has unexpected type 'NoneType' QObject.connect(QObject, SIGNAL(), SLOT(), Qt.ConnectionType=Qt.AutoConnection): argument 3 has unexpected type 'NoneType' Method "wired" should get information about interface: def wired(self, Interface): print Interface So, the question is pretty easy: how to call method via "connect" with argument? Is it really possible? Using such call, but not as one of connect's parameters, it works well: self.wired(Interface).

[opensuse-programming] Finally start to learn programming
by Malte Gell 13 Feb '13

13 Feb '13

Hi there, I´ve been a Linux user for many years, but I´ve not yet learned to code. I speak some Bash and have good general knowledge about x86 hardware, but that´s all. What would you recommend how to start learn programming? Would you start with a scripting language like Python or Perl or just with C/C++? Automating things or controlling apps with Perl/Python would already be a good thing. What do you say? thanx Malte -- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-programming+owner(a)opensuse.org

[opensuse-programming] getpwnam() -> too many open files ??
by Per Jessen 07 Feb '13

07 Feb '13

I've got a new daemon that needs to run on openSUSE 12.2 and 11.0. There is no problem on the former, but on 11.0 I run into $SUBJ every now and then. Not frequently, but it's a problem. Pseudo-code: fork() the child closes stdin, prepares to stdout write to a pipe getpwnam() so I can setuid() execv(). Why would the getpwnam() call result in too many open files?? -- Per Jessen, Zürich (0.1°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse-programming+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-programming+owner(a)opensuse.org
