the bandwidth of long fat pipes (i.e. 100Mbps+ trans-oceanic or trans-continental links). Bandwidth-delay products up to 64MB are supported. Also add support (not compiled by default) for the None cypher. The None cypher can only be enabled on non-interactive sessions (those without a pty where -T was not used) and must be enabled in both the client and server configuration files and on the client command line. Additionally, the None cypher will only be activated after authentication is complete. To enable the None cypher you must add -DNONE_CIPHER_ENABLED to CFLAGS via the make command line or in /etc/make.conf. This code is a style(9) compliant version of these features extracted from the patches published at: http://www.psc.edu/networking/projects/hpn-ssh/ Merging this patch has been a collaboration between me and Bjoern.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

|
# The strategy used for options in the default sshd_config shipped with
|
|
# OpenSSH is to specify options with their default value where
|
|
# possible, but leave them commented. Uncommented options change a
|
|
# default value.
|
|
|
|
# Note that some of FreeBSD's defaults differ from OpenBSD's, and
|
|
# FreeBSD has a few additional options.
