Re: IBM ssh gateway

Hi Folks,

Can anyone help interpret this? I am fairly certain the problem lies with
IBM but I am no crypto expert. Is (for instance) the server rejecting the
connection because (say) it does not understand ECDSA? Unfortunately I do
not have an older instance of cygwin ssh to try that theory out. The
failure is recent. I upgraded my cygwin instances over xmas.

My primary concern is that the latter (linux) connection (after ~~~) may
fail after a future upgrade.
I would definitely check with your local network security folks. When I was last at IBM I had trouble connecting from a certain machine -- just that one -- and nobody could figure out why. Finally, it turned out that I had a lot of locales installed and the long list of supported languages announced by my ssh client triggered some firewall rule.

Meanwhile, have you tried using `ssh -i' with a different key type? That should clarify whether it's an ECDSA issue, at least.
