In the logs, you can see actual commands issued. Have you compared those?

Hello,

I stumbled upon this weirdness when benchmarking offloadable SSH ciphers using the rsync transfer method.

In short, splitting up the RsyncSshArgs I use on multiple lines fails:

'-e',

'$sshPath -l ubuntu',

'-C',

'-c aes256-...@openssh.com'


and combining them on one line works (but may be a fluke):

'-e',

'$sshPath -l ubuntu -C -c aes256-...@openssh.com'


Errors vary between these:

No files dumped for share /

rsync error: syntax or usage error (code 1) at main.c(1572) [client=3.1.2.0]

The suspect is some escaping problem due to the @ sign since it indicates an array in Perl. However, escaping it (-c aes256-gcm\@openssh.com) does not help. I am not into Perl more than that. Any thoughts?

Best regards,

Johan Ehnberg
