I have noticed something odd with the version of openssh on the stable
version of freebsd(Version OpenSSH_2.9 FreeBSD localisations 20010713, SSH
protocols 1.5/2.0, OpenSSL 0x0090601f).

When using ssh1 not prob all good, but when I use ssh2(ie ssh -2 hostname)
and then run trafshow or tcpdump I noticed a crazy amount of traffic
generated, ie a constant flow of 40-50K per sec or more just by the ssh
session, yet under ssh1 it only gen's about 1-3K per sec.

I tried this on an older version of ssh and this does not re-occur.  Can
someone else try this and tell me what you get....ie

ssh from any box to a FreeBSD4.4 stable box using ssh -2 hostname.  Then do
a 'trafshow port 22' and see what your bytes/sec is after a 1min run or so.

From what I can tell it is a problem with sshd not the client.

Thanks.
