Severity: wishlist
Tags: patch


It is sometimes desirable to suppress the exact package version of
openssh that is reported during the initial protocol handshake.

While attempts we made to more completely deal with this upstream were
rejected[1], the "EXTRAVERSION" variable appears to be a Debian-specific
change.  This means there should be a way to have a Debian-specific
sshd variable be proposed to disable the EXTRAVERSION portion of the
protocol greeting:


instead of

SSH-2.0-OpenSSH_5.1p1 Debian-8

This patch introduces ReportExtraversion (which defaults to "yes").  When
set to "no", "Debian-8" is left off the protocol greeting.
