Zitat von Sebastian Nickel - Hetzner Online AG <[email protected]>:
Hi, I tried "netstat -su" and it showed me many UDP send buffer errors. So I tried to set "net.core.wmem_max" to 8388608 (8m). It did not help. I googled a bit and found some network tuning guides for linux. I ended up with the following sysctl.conf: """ net.core.rmem_max=8388608 net.core.wmem_max=8388608 net.core.rmem_default=262144 net.core.wmem_default=262144 net.ipv4.udp_mem=8388608 12582912 16777216 net.ipv4.udp_rmem_min=16384 net.ipv4.udp_wmem_min=16384
These are new since kernel 2.6.25, i wonder what values they had before they get tunable. I had suspected that the net.core.* values will apply in case the specific net.ipvX.* values are not present.
May i ask what your traffic numbers are on this resolver? Regards Andreas _______________________________________________ Unbound-users mailing list [email protected] http://unbound.nlnetlabs.nl/mailman/listinfo/unbound-users
