Re: sftp from i - no love from remote server

We’ve tried ping, telnet, and traceroute.

Ping no replies. (Though this proves nothing like you say because pings to other servers we can sftp to also gets no replies).
Traceroute confirmed to our network engineer the traffic was making it off our server.
Remember, we can connect to other vendors from this lpar using same sftp method.

I think I will compare the traceroute between the no love server and a well know server as you suggest or even a server we can connect to. That could be enlightening.

I agree with TRACEROUTE or PING although sometimes network people block useful tools because they heard decades ago they could be used to launch a denial of service attack against a site. But, let's face it, if they were so easy to be used for a DOS attack would nra.org continue to let them through?

So, yes, I would try those commands first but just because they fail may not mean your production lpar cannot speak to that target location. Try those commands (Windows calls TRACEROUTE tracert). Try them to a different target from your production (like nra.org) and try the target from a known good source (like your development lpar).

You could start with a traceroute. Like I said, try it from a Linux box
first and do some detective work where the light is better.

How can we provide evidence the traffic is making it to them but they are
refusing?
