Default Solaris 10 - very slow ssh connection

Hi

I've just installed Solaris 10 11/06 on an dual 400Mhz, 2GB Ultra2.
Logging in to it using ssh takes approx three minutes or more before I
get the password prompt. Watching on the console I see the message:
sshd[pid]: Failed publickey for liam from 192.xxx.xxx.xxx 2

However, I am not trying to do a public key login - I am doing a straight
userid/password login. I have turned off name resolution
(LookupClientHostnames no) in sshd_config.

Any ideas?
Cheers, Liam

Something else is looking up names. I'd fix name resolution.

/etc/hosts.allow ?

Quite possibly. The underlying issue is that you should either have a
functioning network nameservice or configure the machine not to use
one, I think :-)

Try

UseDNS no

as well. The delay is almost certainly because of a reverse IP lookup.
The best way to fix this is to have a working reverse zone for your
local IP range: you can always run a local BIND if your network admin
isn't doing reverse DNS for you.

sorry to hijack; did you use burned cd's or cd's from Sun? I tried to
install s10 11/06 on 2 ultra 2's and get an error can't load boot
device. 03/05 worked fine.

Hi Joey

I spent the $50 and got a DVD drive for my Ultra 2 so I didn't have to
mess with the stack of CDs. I used the downloaded image from Sun to
burn the DVD.

Cheers, Liam
