Re: [Emc-users] Running EMC2 from another, local app
Thanks Eric, That did the trick. And my apologies to the group for posting the same question twice. I got nervous first thing in the morning when I did not see my post from the night before.

At 01:15 PM 3/11/2008, you wrote: This most certainly is not an EMC problem, but a network setup problem. Chances are you don't have telnet server running on the EMC machine. Telnet is a pretty deprecated service, and may not be enabled by default anymore. Can you use ssh? ssh is served by the sshd daemon, I forget what the name of the telnet daemon is (inetd, xinetd ?) telnet is also wide open to the network, passing user names and passwords in the clear. ssh is a much better application, as is sftp for transferring files. Both encrypt the user name and password. That being said, on some machines, the telnet deamon is in.telnetd and on others it's just telnetd. The telnet deamon runs under either inetd or xinetd If it's xinetd, got to /etc/xinetd.d, vi the telnet startup file and set disable = no. If it's running under inetd, vi the /etc/inetd.conf file and delete the comment in front of the in.telnetd line. In either case, you have to restart inetd/xinetd by typing pkill -HUP inet on the command line. Depending on which account you are doing this from, you may have to use sudo in front of all these commands. On the EMC machine, type : telnet localhost If you get the same refused message, the machine is not serving telnet requests, and you'll have to enable the server. I don't know enough about the way you set up your system to advise further. Jon Mark - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Running EMC2 from another, local app
Jon, Don't confuse the telnet daemon with the telnet tool. The tool lets you specify any port to connect to using tcp. So. telnet localhost 80 will connect the http server. telnet localhost 25 will connect to the mail server.
