Description of problem: I have a dhclent-enter-hooks script that, when eth1 is bound to a new IP address, generates a DNS zone file with that address, reloads named, and restarts openvpn, to re-establish a secure channel for e-mail delivery between university and home server. As it turns out, quite often, after a network outage, I get the following sequence of events: Sep 10 04:54:57 freie dhclient[18447]: bound to 201.82.34.171 -- renewal in 4950 seconds. Sep 10 04:55:07 freie openvpn[11587]: NOTE: setsockopt SO_SNDBUF=65536 failed Sep 10 04:55:07 freie openvpn[11587]: NOTE: setsockopt SO_RCVBUF=65536 failed Sep 10 04:55:07 freie openvpn[11587]: Note: enable extended error passing on TCP/UDP socket failed (IP_RECVERR): Socket operation on non-socket (errno=88) Sep 10 04:55:07 freie openvpn[11587]: UDPv4 link local (bound): [undef]:7189 Sep 10 04:55:07 freie openvpn[11587]: UDPv4 link remote: 143.106.7.165:7189 Sep 10 04:55:07 freie openvpn[11587]: read UDPv4 []: Socket operation on non-socket (code=88) This last message is repeated ad infinitum, at a rate of thousands per second. Eventually, /var/log/messages fills up. This is not a new problem: I've had it for years, I thought I'd reported it before, but fortunately network outages don't hit very often, and the problem doesn't hit every time there's an outage. Version-Release number of selected component (if applicable): openvpn-2.1.1-2.fc13.x86_64 How reproducible: Frequently, but not after every network outage
I added a copy of this bug to the upstream bugtracker: https://community.openvpn.net/openvpn/ticket/75 However, I wonder if this can be SELinux related. Can you share your openvpn config? I'll have a check if I can reproduce it on my box. I'm running openvpn-2.1.1-2.fc13.x86_64 as well.
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '13'. 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 13'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 13 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 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
