Disallow leading lines before the ident for server (#102) Per RFC4253 4.2 clients must be able to process other lines of data before the version string, server behavior is not defined neither with MUST/SHOULD nor with MAY. If server process up to 50 lines too - it may cause too long hanging session with invalid/evil client that consume host resources and potentially may lead to DDoS on poor embedded boxes. Let's require first line from client to be version string and fail early if it's not - matches both RFC and real OpenSSH behavior.

Multi-binary compilation
========================

To compile for systems without much space (floppy distributions etc), you
can create a single binary. This will save disk space by avoiding repeated
code between the various parts.
If you are familiar with "busybox", it's the same principle.

To compile the multi-binary, first "make clean" (if you've compiled
previously), then

make PROGRAMS="programs you want here" MULTI=1

To use the binary, symlink it from the desired executable:

ln -s dropbearmulti dropbear
ln -s dropbearmulti dbclient
etc

then execute as normal:

./dropbear <options here>
