Which version of vpnc are you using? Is nscd's init script being called with "restart" or "reload"? If it's "restart", is vpnc passing these descriptors to the init script? vpnc-0.3.2-3 As far as I can tell the vpnc code (vpnc-connect) is not calling the nscd init script, but just calling "ncsd -i hosts" directly. According to the manpage that is supposed to invalidate the hosts cache. I did (once, not sure how to repeat it) get nscd into a state where I couldn't reload from the initscript because of selinux failures. But I haven't been able to reproduce that one so I didn't really want to talk about it. Fixed in selinux-policy-targeted-1.25.1-7 Thank you, Daniel. Any chance the fix can be backported to FC3? |

Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. run vpnc and connect to my VPN 2. check the logs. 3. Actual Results: nscd threw the selinux errors and nameservice wasn't flushed or failed. Expected Results: nscd should be allowed to talk over the tunnel device. Additional info:
