[OpenIndiana-discuss] Slow ssh login?

[gary at genashor.com]

+1 I've been trying to figure this out for years. But mine is on bare metal. I tried everything I could think of but no luck. The strange thing is that it sometimes is fast, but most times I wait about several seconds.

Hi, all.  I've got an issue that is bugging me.  I've got an OI 151a7 VM and

ssh to it takes 15 seconds or so, then I get a prompt.  It's not the usual

reverse dns or gssapi stuff, since my backup node is also OI 151a7 and it

responds instantly to the ssh request.  Google has not turned up anything

useful except for the usual suspects that are innocent in this case.  The

only hint I can see is if I give '-v' on the client, I see this:

Any thoughts where to look?  It's got to be something that is different

between the two OI hosts, but offhand, I'm not sure where to look.

Thanks...
