I'm using lvs to load balance several hundred ssh and telnet sessions. The problem I'm having is my ipvsadm table does not show the actual number of connections.

the ipvsadm output of ActiveConn etc, is a complete fabrication for LVS-DR and LVS-Tun. The director doesn't see the reply packets from the realservers and can't tell if the realserver drops the connection. The output from ipvsadm is guesses based on likely timeouts etc.

The numbers are there to tell if the machines are balanced
and are operating at all. If your setup isn't working the first thing we ask is for the output of `ipvsadm`.
