tuning synology ds209

first, I upgrade to DSM 3.0-1354
allow ssl/tls connection only for my ftp
but problems happen, filezilla and winscp can't connect to the box

after a little bit googling,
I found I need to install bootstrap and install ipkg also openssh-sftp-server

my ds209 is Marvell Kirkwood mv6281 ARM Processor

I use http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/cross/unstable/syno-mvkw-bootstrap_1.2-7_arm.xsh
wget http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/cross/unstable/syno-mvkw-bootstrap_1.2-7_arm.xsh
sh ./syno-mvkw-bootstrap_1.2-7_arm.xsh
ipkg update
ipkg upgrade

http://forum.synology.com/wiki/index.php/How_to_setup_a_sftp-server
ipkg install openssh-sftp-server
modify /etc/ssh/sshd_config to use

/volume1/@optware/libexec/sftp-server

# override default of no subsystems
#Subsystem      sftp    /usr/libexec/sftp-server
Subsystem       sftp    /volume1/@optware/libexec/sftp-server

also I install samba binutils procps htop bc busybox util-linux xpdf nano e2fsprogs
and etc ...

and there now is `watch` `tr` `xargs` `unix2dos` `blkid` binaries and much more which is missing before
