I found, after digging around for a good while, that changing these keys: net.ipv4.netfilter.ip_conntrack_udp_timeout=480 net.ipv4.netfilter.ip_conntrack_udp_timeout_stream=900
seems to work on FC6 (2.6.22.4-45.fc6). But: Do I both need them ? and what is the best "minimal" value for those keys ? tia, Ron Ron Croonenberg wrote: > Hi Jason, > > I got rid of this one: "Unable to authenticate to AFS because > Authentication Server was unavailable." > That appeared to be a firewall issue. > > I do see the timeout happening, every so many minutes, did anyone solve > that port.
