Stuck at Rust redis replication stage 6 (sending handshake 2/3)

please help

@gregor-tokarev can you explain your problem in a bit more detail? What do you think the issue is, what have you tried so far?

I think maybe problem is in the way how I sending tcp requests.

I tried to fully read response.
Tried to flush streams.

But nothing worked for me.

It may be helpful if I should better understand how tester works, because if I mannualy run 2 instances of redis everything works fine.
