Unable to telnet to EFA appliance

[cybermud]

I have tried to telnet to my new EFA VM both fro within and outside the network before I put it into production, and in all cases, the telnet fails. Is there a portion of setup that I am missing to allow SMTP communication?

telnet?

@shawn

telnet SERVERNAME 25

Oh, I see

1) Can you ping your appliance?

2) Can you access the web interface?

3) Is Postfix running on your EFA?

Code: Select all

sudo service postfix status

1) I can ping the appliance

2) I can access the web interface (which also shows postfix to be running)

3) checking the status via the shell reports that it is running


Is there a firewall of some sort running on the E.F.A. appliance itself?

[DaN]

Don't think so. Maybe there is a firewall between your telnet and efa?
Windows Firewall?
AntiVirus with feature x?

Is there a firewall of some sort running on the E.F.A. appliance itself?

There is. You can test by turning it off...although port 25 should be permitted out of the box.

Code: Select all

sudo service iptables stop

I did a netstat and determined that the connection is making it to the E.F.A. VM...but it hangs there and eventually drops with no data being transmitted. If I start typing HELO in my telnet session it drops right away, whish is what I thought was a connection not being recieved. I tried hooking up a POP3 fetcher to the appliance and it has a similar behavior--opens a connection and hangs. netstat shows the connection for a minute or so, then the POP3 grabber gives up and errors out.

I'll try to re-install. It sounds like something is goofy with postfix.

It could be also a problem with the hypervisor!?

You could run a clone of the vm locally.

Hello I m the same problème.
Telnet EFA 25 don't open.
Please help me...

Cyril,

Tell us how you have EFA configured so we can start making some guesses as to what your problem is.

[DaN]

Did you use a Windows client? Is the telnet client installed? Did you try putty?
