Hi I have been facing a strange connectivity problem from CentOS and Fedora boxes.
When I telnet to $ telnet adp.eease.com 443
it works fine some times and every 5-10 tries or so it says connection refused. And this does not happen from my windows box.
Can anyone from this list try this on their linux installation and see if they get the same behaviour?
Thanks Tharun
I could only connect 3 times out of 10. This was from my Mac laptop running Leopard. It would appear that something abnormal is happening on this host.

Thank you I tested this today morning from the windows machine and it is behaving the same ( connection refused ). So I guess Its the host. I have a call with the Host admin some time today. This test should help me point the issue to him.
Thanks Tharun

[lanny@dell2400 ~]$ telnet adp.eease.com 443 Trying 209.168.243.5... telnet: connect to address 209.168.243.5: Connection refused telnet: Unable to connect to remote host: Connection refused [lanny@dell2400 ~]$
BTW: I have telnet and anonymous FTP disabled on my web sites. Suggest the person in charge of that box switch to SSH.

I'd assume that 'telnet hostname 443' is intended to be a test for an https web service - which should in fact not permit a connection without ssl encryption. The linux version of telnet probably tries to do some options negotiations before it says it is connected and perhaps the windows version doesn't. A better test would be wget https://adp.eease.com

wget behaves the same way $ wget https://adp.eease.com --2009-08-27 20:23:30-- https://adp.eease.com/ Resolving adp.eease.com... 209.168.243.5 Connecting to adp.eease.com|209.168.243.5|:443... failed: Connection refused.
The network team at that site is trying to figure out what the problem is. Will update once they get back.

Just for completeness, s_client(1) would be an alternative for testing purposes, too.

This is a nice tool. Gives the following error sometimes.
$ openssl s_client -connect adp.eease.com:443 socket: Connection refused connect:errno=29
Thanks for pointing this tool out.
