Jason, The setting is in seconds...and I would suggest 1 hour for RDP.
Persistence > 15 minutes? Some services such as TELNET, SSH, FTP & Terminal Server (RDP) may require a persistence setting of greater than 15 minutes. If you require a persistence of greater than 15 minutes then you will need to increase the load balancers TCP time out value. The TCP time out can be set as a command in your firewall script: ipvsadm --set 3600 0 0 This example sets the TCP timeout to 1 hour, you should make sure this timeout is the same as your required persistence setting. A protocol with a long session & persistence enabled such as Terminal Server RDP maintenance can become problematic because clients that disconnect and re-connect will still go to the same server for the length of the persistence timeout even if the server fails or is taken down for maintenance. You will probably want the following in your sysctrl.conf file: echo 1 > /proc/sys/net/ipv4/vs/expire_quiescent_template echo 1 > /proc/sys/net/ipv4/vs/expire_nodest_conn 2009/1/19 Jason Ledford <[email protected]> > > I am using ldirectord with wlc and balancing Microsoft term servers.
