I'll try to put it all together:
1) Edit /etc/distcc/hosts on all machines and insert the values you
want. Your config seems correct
3) FEATURES="distcc"
4) put MAKE_OPTS="jx" on each machine, where x is the number of jobs
distccd should accept for that machine.
5) Check /etc/conf.s/distcc on each machine - "LISTEN" and "ALLOW" are
vital, and there is again the flag "-j" set it equal to the j from
MAKE_OPTS. example:
DISTCCD_EXEC="/usr/bin/distccd"
DISTCCD_PIDFILE="/var/run/distccd/distccd.pid"
DISTCCD_OPTS="${DISTCCD_OPTS} --port 3632"
DISTCCD_OPTS="${DISTCCD_OPTS} --log-level critical"
DISTCCD_OPTS="${DISTCCD_OPTS} --allow 10.0.1.0/24 -j 6"
DISTCCD_OPTS="${DISTCCD_OPTS} --listen 10.0.1.10"
DISTCCD_NICE="19"
Last: restart the daemon at each machine with "/etc/init.d/distccd
restart" and you should be fine.
To checkout if the number of listening distcc daemons is correct: "ps
ufax | tr -s ' ' | grep distcc"
