I am investigating the monitoring capabilities provided by PCP. I have installed PCP on three machines, PMCD in every machine is up and running. But if I want to poll metric from other two machines, it won't work. The log says no route to the host, connection refused. eg. From host haoscar, type following command: #pminfo -h oscarnode1 kernel I wonder what I shall do to let the remote monitoring capabilities be realized in the distributed environment. What shall I do to let the PCP communicate with each other? Thank you very much for your kind help. I really appreciate your great help. Best regards.

I am really grateful. ah, in that case, you must have some sort of firewall between the two or network security installed on the machine. If linux, it's probably iptables. "iptables -L -n -v -t filter" or "iptables -L -n -v -t nat" will likely show you which machine is blocking packets for everything but port 22. If you can open up port 4321, that will allow the pcp server to accept connections from the network. Be sure to turn on the appropriate security features of pcp, and/or only open port 4321 to your local network, otherwise everyone in the world will be able to access your machine. 'telnet remote 4321' from the client machine can help verify if the port is open or not. - Kevin Wang From jxu004@latech.edu Thu Feb 12 20:24:45 2004 Received: with ECARTIS (v1.0.0; list pcp); Thu, 12 Feb 2004 20:24:49 -0800 (PST) Received: from LaTech.edu (selene.LaTech.edu [138.47.18.25]) by oss.sgi.com (8.12.10/8.12.9) with SMTP id i1D4OiKO013896 for ; Thu, 12 Feb 2004 20:24:45 -0800 Received: from localhost (localhost [127.0.0.1]) by LaTech.edu (Postfix) with ESMTP id 86AF230995B; Thu, 12 Feb 2004 22:24:44 -0600 (CST) Received: from LaTech.edu ([127.0.0.1]) by localhost (selene.latech.edu [127.0.0.1]) (amavisd-new, port 10024) with LMTP id 36633-01-11; Thu, 12 Feb 2004 22:24:44 -0600 (CST) Received: from localhost (helius.LaTech.edu [138.47.18.18]) by LaTech.edu (Postfix) with ESMTP id 9C5433098D5; Thu, 12 Feb 2004 22:24:43 -0600 (CST) Received: from 138.47.37.207 ([138.47.37.207]) by webmail.LaTech.edu (IMP) with HTTP for ; Thu, 12 Feb 2004 22:24:43 -0600 Message-ID: <1076646283.402c518b936ea@webmail.LaTech.edu> Date: Thu, 12 Feb 2004 22:24:43 -0600 From: Jie Xu To: Max Matveev Subject: Re: connection refused to a remote PMCD References: <1076483051.4029d3ebd042b@webmail.LaTech.edu> <16425.55896.625582.758850@kuku.melbourne.sgi.com> <1076486047.4029df9f1c9fd@webmail.LaTech.edu> <16425.58547.89558.415146@kuku.melbourne.sgi.com> In-Reply-To: <16425.58547.89558.415146@kuku.melbourne.sgi.com> MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 User-Agent: Internet Messaging Program (IMP) 3.2.2 / FreeBSD-4.8 X-Originating-IP: 138.47.37.207 X-Virus-Scanned: by amavisd-new at latech.edu Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from quoted-printable to 8bit by oss.sgi.com id i1D4OiKO013896 X-archive-position: 354 X-ecartis-version: Ecartis v1.0.0 Sender: pcp-bounce@oss.sgi.com Errors-to: pcp-bounce@oss.sgi.com X-original-sender: jxu004@latech.edu Precedence: bulk X-list: pcp Thank you sir.

If it is appended in INPUT chain, it won't work. that's normal. Most firewall rules are evaluated from top to bottom (or first to last) and the first rule that matches typically exits the evaluation chain (not always true) thus, you have to put accept or allowable rules first, and then you have a global "reject everything" at the end. > Thanks again for your great help.
