Greg, I'm not sure about whether or not you'd need to do anything after changing the hosts file. I think I remember a system administrator having to restart something called nscd after making this sort of change, but it's not even running on the system I'm looking at now.
On that machine, I see the external IP address specified in the hosts file. There's also a host.conf file with this in it: order hosts,bind I think that makes sure that the hosts file is actually used, instead of skipping directly to the name server. Your system might also have a file /etc/nsswitch.conf file with a line like this: hosts: files nisplus nis dns You'd just want to make sure that "files" shows up first on that line. This is an odd problem. I don't know much about system administration so maybe someone else can chime in, or maybe there's someone in your network group who might have an idea? ----- Keith, Thanks for the reply. Yes it is a Linux machine, and I also thought it was an issue with the hosts file which did make reference to dSpace-Production. Running "hostname" returns "dSpace-Production". Do I need to specify the local or external ip? And does changing the hosts file require a reboot (or anything else) for changes to take place. I appreciate your time.

This may be a problem with the network configuration on the machine. Is this a Linux machine? If so, what name comes up when you use the "hostname" command? Is there an entry for that name in the /etc/hosts file? What about an entry for "dspace-Production"? ----- Hello, I am no longer getting any HELO command errors in the error log when clicking the feedback link or trying to register a new user. The following is the error message. Any hints as what to look for would be greatly appreciated. Thank you. RHEL 5 dspace 1.5.1 tomcat postgresql I can telnet to the smtp server using port 25 so I don't think it is any type of network or firewall error.
