Hi,

sorry for this new (semi) OT: I'm trying to use "weighted least connection" algorithm with LVS, I don't want to use rsh or ruptime tools, but ssh doesn't seem to work (my lvs.cf configuration: rsh_command=ssh, load_monitor=uptime).

I'm using openSSH 2.2.0, and I've configured it as follows:
PermitRootLogin yes
IgnoreRhosts no
RhostsRSAAuthentication yes
RSAAuthentication yes

I've added /root/.shosts file and filled it with "lvs_ip_address root" entries.

If I set "RSAAuthentication yes" ssh server cotinues asking me my RSA key password even if I'm trying to connect from a "known" (=present in /root/.shosts file) host, if I set "RSAAuthentication no" ssh server replies me "permission denied".

As a result, in /var/log/messages i find a lot of messages of this kind:
Sep 26 19:19:43 lvs1 nanny[1708]: The following exited abnormally:
Sep 26 19:19:43 lvs1 nanny[1708]: running command  "ssh" "172.16.0.22" "uptime"
Sep 26 19:19:43 lvs1 nanny[1708]: failed to read remote load

Where I'm going wrong?

P.S.: I'm running ssh server via inetd and have added right entries in /etc/hosts.allow and hosts.deny files.
