Hello:
Using rsync
over ssh
from my box with a GbE port to a WD-MBL is really very expensive, more so in the light of my not needing compression or encryption since everything is done inside my local network with no access from the outside.
Compression can be disabled but not encryption.
By expensive I mean the highest throughput obtained being under 7.50MiB /s with CPU load of ~ 100% (kswap 9% + Dropbear 67% + rsync 22%).
For a GbE to GbE link it is nonsensical.
I was advised that Dropbear does not support -c none
but today I came across this:
Dropbear - Features and Changes:
[https://matt.ucc.asn.au/dropbear/CHANGES]
--- snip ---
2013.56 - Thursday 21 March 2013
Allow specifying cipher (-c) and MAC (-m) lists for dbclient
Allow using 'none' cipher or MAC (off by default, use options.h). Encryption
is used during authentication then disabled, similar to OpenSSH HPN mode
--- snip ---
I queried it via command line and got this:
root@OpenWrt:~# ssh -c none
ssh: This Dropbear program does not support 'none' cipher algorithm
ssh: Exited: No valid ciphers specified for '-c'
root@OpenWrt:~#
How can it be enabled?
It would be a great thing to be able to use ssh
in situations where you don't need encryption, such as a local network file transfer.
Thanks in advance,
PCL
