<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Hi everyone,<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Wanted to follow up on my inquiry. It turns out that by problems were stemming from the Linux firewall blocking necessary ports. Since my network is completely disconnected from the outside world, I totally disabled the firewall, for the time being. This allowed me to get through the installation manual's testing without error. I plan on leaving the firewall off for the present time, at least until I can become more knowledgeable with networking. Unless of course, this could lead to problems with MPICH.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks to everyone for their help,</DIV><DIV><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate;
