Hello all, I'm using dropbear compiled from buildroot: $ grep DROP .config .config:BR2_PACKAGE_DROPBEAR=y .config:BR2_PACKAGE_DROPBEAR_DISABLE_REVERSEDNS=y .config:# BR2_PACKAGE_DROPBEAR_SMALL is not set
From the machine with dropbear, I seem unable to activate compression: # scp -C -p -i /etc/dropbear/dropbear_dss_host_key /root/*.dat user@remote: WARNING: Ignoring unknown argument '-C' 20110905-125726.dat 100% 16KB 16.5KB/s 00:00 20110905-125745.dat 100% 16KB 16.5KB/s 00:00 20110905-125803.dat 100% 16KB 16.5KB/s 00:00 But the option is present: # scp usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 [...] [[user@]host2:]file2 It's actually the same thing with ssh: # ssh -C -i /etc/dropbear/dropbear_dss_host_key noy@lpsc-ssh WARNING: Ignoring unknown argument '-C' Except that I don't even see -C as an option if I do "ssh --help" Compression actually works fine when using dropbear as a server: $ ssh -Cv root@embedded ... debug1: kex: server->client aes128-ctr hmac-md5 z...@openssh.com debug1: kex: client->server aes128-ctr hmac-md5 z...@openssh.com ... debug1: Enabling compression at level 6. -- Guillaume Dargaud http://www.gdargaud.net/
