Is it possible to get the condor_q command to prefer the internal ipv4
address without setting ENABLE_IPV6=False?
IIRC, if the IPv4 address is "private" in the CIDR sense (e.g.,
192.168.* or 10.*), then HTCondor will almost always prefer a "public"
IPv6 address, because it doesn't know if two "private" addresses can talk
to each other. However, you _can_ tell HTCondor that two machines
with "private" addresses are on the same network --
PRIVATE_NETWORK_NAME = the-same-value-on-both-machines
PRIVATE_NETWORK_INTERFACE = 192.168.*
-- by including if the config file on both machines. In such a case,
HTCondor will always prefer to use both machines'
PRIVATE_NETWORK_INTERFACE.
