about

This page describes how to compile dropbear to run in Technologic System's TS-Linux distribution. We're using the TS-7260.

compiling

crosstool setup

download and setup ts crosstool package

• At the time of this writing, I downloaded Linux Crosstool gcc-4.0.1-glibc-2.3.5 -- unknown (05-20-2006)

ftp://ftp.embeddedarm.com/ts-arm-linux-cd/cross-toolchains/crosstool-linux-gcc-4.0.1-glibc-2.3.5.tar.bz2

move it to / and unpack it

cd /
sudo tar -xf crosstool-linux-gcc-4.0.1-glibc-2.3.5.tar

add it to your path

arm@crow:~$ cat ~/.bash_profile | grep cross
PATH=/opt/crosstool/gcc-4.0.1- glibc-2.3.5/arm-unknown-linux-gnu/bin:${PATH}

dropbear ssh server and client

download dropbear

• At the time of this writing dropbear was at version 0.49
• [dropbear home]

wget http://matt.ucc.asn.au/dropbear/releases/dropbear-0.49.tar.bz2

compile dropbear

export CFLAGS="-Os -static -Wall"
export LDFLAGS="-static"
./configure --host=arm-unknown-linux-gnu --build=arm --disable-zlib

make

make PROGRAMS="dropbear dbclient dropbearkey dropbearconvert scp" MULTI=1

move to usr/sbin

• dropbearmulti is primary binary, the rest are symbolic links to it

arm@crow:~/dropbear-0.49$ mv dropbearmulti ../tslinux/usr/sbin
arm@crow:~/tslinux/usr/sbin$ ln -s dropbearmulti scp
arm@crow:~/tslinux/usr/sbin$ ln -s dropbearmulti dropbearconvert
arm@crow:~/tslinux/usr/sbin$ ln -s dropbearmulti dropbearkey
arm@crow:~/tslinux/usr/sbin$ ln -s dropbearmulti dbclient
arm@crow:~/tslinux/usr/sbin$ ln -s dropbearmulti dropbear

arm@crow:~/tslinux/usr/sbin$ ls -l | grep drop
