RE: [Freeipmi-devel] BMC and RSH/NIS conflict

[anand . manian]

Am pretty sure that merely giving the BMC an IP address different from that
of eth interface it uses did *not* solve the rsh hang problem at our site.

Are we sure that at LLNL, the eth interface used by BMC was the same as that
used by rsh traffic?

This may not be feasible for most institutions, but at LLNL, we gave the
BMCs a different IP address than the NIC.  Solves the problem AB
mentions plus a handful of setup/management annoyances.
