Hi Fred, Yes, you're so right. Only, in our case, the client is not willing to create 3 virtual RHEL instances from the physical server. They give a reason that their vendor support costs will then become three-fold.

You could run 3 virtual Red Hat instances (each with 1 IP) and 3 separate ARS Installs with no problems. Each Virtual Red Hat instance is separate (1 instance does not see the others) so you can install them all on the same port. I believe one of our physical development servers here is something like 6 or 8 virtual Red Hat servers.

Our client gave us one physical server with 3 virtual IP Addresses. And asked us to install AR Server on each of the virtual IP Addresses, all on same port. I guess I’m not able to use iptables restriction because I want to use the other IPs too , but for a second and third instance of AR Server. I’ll write back to them stating that the current version of AR Server doesn’t support this. Perhaps I should raise an RFE.

I looked through all the ar.conf parameters and flags supported by arserverd and it does not look like there is a way to tell arserverd to listed on a specific IP. You could use iptables to restrict access on those other IP addresses since you are on linux.

They will bind to a TCP port if one is specified (and/or use portmapper if that is set). If you are not connecting to the AR Server one item to check is the /etc/hosts file. See if the name you used for your AR Server is listed as a valid name for an IP. If it is then check if your DNS server has it listed. Example: AR Server = arsdev01 Physical Server = devserver1 /etc/hosts file # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 192.168.1.101 devserver1 devserver1.mycorp.com arsdev01 DNS has a cname record for arsdev01 pointing to 192.168.1.101 Fred -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Narayanan, Radhika Sent: Tuesday, February 18, 2014 7:14 AM To: arslist@ARSLIST.ORG Subject: arserverd binding to 0.0.0.0 ** Hi List, How can I make the arserverd executable listen on a given, specific IP Address and not on 0.0.0.0? By default, arserverd binds to the interface 0.0.0.0. My RHEL 6.4 server has 5 IP Addresses. I want it to bind only to one of the 5 IP Addresses that I mention in armonitor.conf. armonitor.conf: /apps/tim/ar/timw0/bin/arserverd.sh -s dc5chw-000 -i /apps/tim/ar/timw0 -l /etc/arsystem/dc5chw-000 In this line, the server name is mentioned as dc5chw-000. I want arserverd to bind only to this IP Address. How can I achieve this?
