Re: xidle(1) not working well
Thanks for replying. My problems with xidle turned out to be mostly caused by a paused Mplayer, which disabled the screensaver. I also ended up doing xset dpms 0 0 0 to allow xlock control over it.

no benefits for this, just use a simple PF rdr-to.

There are some benefits such as in layer 7 but relayd is going through a transition incorporating priv seperation code used elsewhere in OpenBSD and if you check the mailing list you'll see there are some bugs at the moment or atleast in 5.1 in this area. So If I was you I'd stick with pf for now or use 4.9 (luckily OpenBSDs history has shown it to be solid enough to do that for years as a service free firewall, just don't expect support) Stu also shows how to get the latest pre major overhaul code here. http://marc.info/?l=openbsd-misc&m=133293448804527

OpenBSD 5.1 XEN HVM DomU - kernel panic
Hi is any body running OpenBSD as a XEN HVM guest? I have a difficult time accomplish that... The XEN guest does boot up and is usable. When f.e. do a cvs checkout of ports the machine panics about every other time. I know that is not really a supported configuration but if someone managed to get this working in a stable manner I'd still appreciate some assistance. If you need any further information, just ask.

bgpd debugging options.
Hi Misc, I am having issues troubleshooting an issue where the error is: Jun 6 13:47:53 openbsd5132 bgpd[15919]: neighbor x.x.x.x (AS 65002 peer 1): parse_capabilities: AFI 1, safi 4 unknown Jun 6 13:47:54 openbsd5132 bgpd[15940]: neighbor x.x.x.x (AS 65002 peer 1): bad VPNv4 withdraw prefix Jun 6 13:47:54 openbsd5132 bgpd[15919]: neighbor x.x.x.x (AS 65002 peer 1): sending notification: error in UPDATE message, optional attribute error And I have tried with the gdb debugging options explained in a previous thread but it looks like I am only able to get it to work when bgpd core dumps. When this error gets logged, bgpd does not core dump, so I need to be able to debug the running process, and I am failing horribly with that. To give some background, this is happening when I am exporting multiple communities from a Junos host to the bgpd host, not when a single community is used. On a single rdomain it is working perfectly. Is it possible for you to make the info that was written down about debugging options for bgpd in the non-public list available here, as per the mail below?

PHP issue with native Apache and ProxyPass
Hello, I have an OpenBSD 5.0 server, running the native Apache and providing a local WordPress instance which works great. The Apache also proxyfies "simple" websites (only HTML/CSS/JS, like xymon, munin, sogo) using the ProxyPass/ProxyPassReverse directives. I wanted to proxyfy another WordPress instance, running on a remote OpenBSD 5.1 installation. So far, the remote installation works like a charm. But when I configure the reverse-proxy, URL with PHP files and variables aren't managed properly. The remote website is located on http://192.168.0.28:80/ (DocumentRoot is /var/www/htdocs). The proxy directives I set up are: ProxyPass /test/ http://192.168.0.28:80/ ProxyPassReverse /test/ http://192.168.0.28:80/ (I modified WordPress so that it publishes itself as https://www.tumfatig.net/test/) Working URLs look like: https://www.tumfatig.net/test/wp-content/themes/twentyeleven/style.css https://www.tumfatig.net/test/wp-includes/css/admin-bar.css?ver=20111209 https://www.tumfatig.net/test/wp-includes/wlwmanifest.xml https://www.tumfatig.net/test/xmlrpc.php Any such URL doesn't work: https://www.tumfatig.net/test/xmlrpc.php?rsd The proxy log says: [Wed Jun 6 10:58:31 2012] [error] [client 82.241.119.38] File does not exist: proxy:http://192.168.0.28/xmlrpc.php?rsd The Web navigator says: 404 Not Found Not Found The requested URL /test/xmlrpc.php was not found on this server. But, from the LAN and the proxy server itself, running `ftp "http://192.168.0.28/xmlrpc.php?rsd"` gets the file properly from the 5.1 server... Anyone gets why only PHP files with variable passed are not translated properly by my configuration ? Thanks a lot. Jo
