SSHD Oh yea another question or possible an answer

[soup4you2]

ok i'm sure we all have either experienced or heard about the ssh slow as snot login problems.. well i've finally been able to track it down.. (seems i dont like waiting 5 min for a password prompt)

if you have a sysctl value of

net.inet.tcp.blackhole=2

it makes it really slow./. why is this and what can be done w/ out loosing the blackhole?

I've never had that problem on my boxes that have the blackhole sysctl variables set.

The usual reason for the delayed password prompt is DNS.

nope not DNS if i'm on my other pc and i ssh in to the direct ip (both internal or external) it still delays. it does it w/ the UDP blackhole also

I used to use one of those floppy based firewalls and you had add your machine to the hosts file or it would just sit there for the longest time.

Yup, DNS. It's like strog suggests, if the host you're connecting to can't properly do a reverse lookup on you it'll stall til it times out and then finally give you the password prompt. Whether or not this is what's happening to you I dunno... I was merely suggesting that the above is the most common reason for the delay.

I was connecting via IP on that setup.

tried it w/ out the entry in hosts.. thought it might have gotten fucky if in the ipf rules i have it going to the hostname in my hosts file (restricting the flow) but that wasnt it.

:( pooh...
