So try replacing `hostname` in worker.pl with something like:<br><br> `ifconfig | grep 192.168 | sed -e 's/^inet addr://' -e 's/ .*//'`<br><br>You may have to adapt this a bit to meet your needs. Im assuming that the only code that will uses these IPs is MosaStore.<br><br>- Mike<br><br><br>----- Original Message -----<br>> From: "Kazutomo Yoshii" <<a ymailto="mailto:kazutomo@mcs.anl.gov"
