Description of problem: openvpn installed by the default installation writes logs to /etc/openvpn, which has context openvpn_etc_t. However if run as a service, openvpn runs in source context openvpn_t. Thus it can't write to the logs (it seems to be able to write to them OK if run directly from root). Presumably, the selinux policy needs a minor mod to allow this? Or else, the default log location needs to be changed (/var/logs seems a reasonable alternative?) Version-Release number of selected component (if applicable):2.1 rc4 i386-redhat-linux-gnu How reproducible: always Steps to Reproduce: 1. Install openvpn 2. Set up config files etc in /etc/openvpn (as specified in openvpn installation doco) 3. Start openvpn as a service Actual results: Selinux error messages and a failure to write logs Expected results: Logs written correctly Additional info:
There is no default configuration for openvpn when it is installed from the Fedora packages. It shouldn't try to write anywhere except where you tell it to. I have a bug open (bug #196564) to remind myself to review the example config files to make sure they'll play nice. Did you just use one of the sample config files verbatim?
BTW, *my* instructions for setting up openvpn are at http://fedoraproject.org/wiki/openvpn (which I should probably include in a README.Fedora in the package). They reference roadwarrior-*.conf in the sample config files, which I personally included in the package (based on the OpenVPN 2.0 docs). Those two files should be totally safe to use as references.

(In reply to comment #1) Firstly, thanks for setting up the package, it greatly simplifies setting up openvpn! > There is no default configuration for openvpn when it is installed from the > Fedora packages. It shouldn't try to write anywhere except where you tell it to. Well, all the docs for openvpn (including yours) say to put the config files in /etc/openserver. If you don't change anything from the sample server config file, that's where it will write the logs. I assumed that was also where I should direct the ipp file; I'll change that back now (but it would be good if the doco made it clear that this should not be changed, as many of the examples floating around the web point the ipp file to /etc/openvpn/ipp.txt). > > I have a bug open (bug #196564) to remind myself to review the example config > files to make sure they'll play nice.

Those two files should be totally safe to use as references. Yep, including those details in the README would be _very_ useful. It's not obvious that the roadwarrior sample conf files are the preferred ones for fedora, nor where the documentation for fedora is.

This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
Yes, this bug still exists. I have duplicated it with Fedora 9 with the config pretty much out of the box.

I have not tried subsequent versions of Fedora though I may one of these days.
