When I do (I've tried various ways):
ssh -v -C -o CompressionLevel=9 user@ip
ssh -v -C -o 'CompressionLevel=9' user@ip
ssh -v -o 'Compression=yes' -o 'CompressionLevel=9' user@ip
ssh -v -o 'CompressionLevel=9' -o 'Compression=yes' user@ip
ssh -v -C -o 'CompressionLevel 9' user@ip
ssh -v -o 'Compression yes' -o 'CompressionLevel 9' user@ip
ssh -v -o 'CompressionLevel 9' -o 'Compression yes' user@ip
I enabled -v
, so I can see connection details and no matter, what I tried, I can't get compression level more than 6, as it shows in verbose output:
debug1: Enabling compression at level 6.
I don't need to set CompressionLevel
in ssh_config
, I need to do it with cli.
I've found some info, that the option CompressionLevel
works only for ssh version 1, but not 2.
How to set the maximum compression level for ssh version 2 protocol?
