Description
When trying to SCP from a local machine to and EC2 instance, using session manager (ProxyCommand is setup in SSH config) - it seems that I have issues sending larger files (60MB for example) and when I get to 8624KB uploaded, I get the following error.
ad packet length 2916819926.
ssh_dispatch_run_fatal: Connection to UNKNOWN port 65535: Connection corrupted
lost connection
My local connection is stable, so am just wondering if I'm hitting any hard limits ?
Contributor guide
Research direction
Start by reviewing the SCP transfer path that uses Session Manager through the SSH ProxyCommand, then reproduce the failure with a file larger than 60 MB and observe the transfer around 8624 KB. Determine whether a documented hard limit or a connection-handling failure explains the corrupted packet; done means the cause and supported transfer behavior are clear.
