Hello,
I tried it too with LVS-NAT, with 2 directors.
I have a master and a "backup" which are
using IPVS-Sync to synchronise the connections
tables. Linux 2.4.10, IPVS 0.9.4
I effectively see the udp synchronization packets
going from master to the backup server. That
brings me to the first question:
1) Is there a way to see the connections informations
that are received by the backup IPVS?
UDP packets are only generated to signal a new
connection, so
2) How does IPVS take care about the Sequence
Numbers when you have to fail over?
3) Are the master/backup role swapped automatically
after a fail over (if you have set "nice_fallback")?
4) What is /proc/sys/net/ipv4/vs/sync_threshold good for?
Thanks a lot for your answers,
Fabrice
