I would like to use socks5 with compression on a slow WAN line.
I use this command : ssh -p 51001 -C -o "CompressionLevel 9" -g -D
Generally this works but I notice there is no difference in speed
if I use CompressionLevel 1 compared tho CompressionLevel 9.
man ssh is not 100% specific if this also applies to dynamic port forwarding:
-C Requests compression of all data (including stdin, stdout,
stderr, and data for forwarded X11 and TCP connections).
Does compression work with Dynamic port forwarding at all ?
Re: Do Compression and CompressionLevel apply to Dynamic port forwardings (socks5) ?
On what data? Measured how? Do you see a difference with compression off
entirely on large amounts of compressible data? Ssh uses the same compression
as gzip, and for a lot of types of data there's a fairly small change (<10%)
between levels 1 and 9.
"all data" is pretty clear IMO. This compresses everything across the wire,
not just some streams.
