Hi
I setup rsync to sync a windows folder with my openwrt. These are video files exported from my desktop typically of 1.6GB that I want access over minidlna on openwrt. It defaults to using ssh. On the internal wired LAN the ssh overhead means the achieved throughput is only about 16-17mbps on a 1Gbps switch with dropbear ssh running at 82% on an Netgear WNDR3700. Since this is an internal home network behind a double-NAT, I dont care about SSH security and want to get rid of the SSH overhead to speed up file transfer.
I tried this command:
rsync --rsh=rsh -aiPv ...<snip>
But it seems dropbear ssh is still utilized with high cpu because there is no rsh on openwrt by default. Google does not return any results for rsh-server on openwrt. a few ip-accounting packages for openwrt seem to support rsh client ony.
Is it possible to compile in support for ciphers : none and macs : hmac-md5-96 using image builder? These seem to be the least overhead options with ssh. What files do I need to change in the dropbear package?
For example If I try this I get
$>ssh user@192.168.1.1 -c blowfish -m hmac-md5-96
Unknown cipher type 'blowfish'
PS: I am already using a custom image created with imagebuilder - just want instructions to modify the source files and compile it as a custom package.
Edit: Found this dropbear: Use macro to set options to set runtime options but no clear instructions how to set it - for example to test blowfish?
Thanks
