Description of problem:
ssh  -o ProxyCommand="ncat --proxy-type socks5 --proxy <host>:<port>  %h %p" <user>@<host>

Does not seem to work with Ncat version 7.91 but works fine with 7.92


Steps to Reproduce:
1. create a sock5 proxy connection "ssh -D <port>"
2. Try using that connection with 
ssh -o ProxyCommand="ncat --proxy-type socks5 --proxy <host>:<port>  %h %p" <user>@<host>

It will break with the supplied version in fedora 35 ( nmap-ncat-3:7.91-8.fc35.x86_64)

But works fine with the version from nmap.org

sudo rpm -vhU https://nmap.org/dist/ncat-7.92-1.x86_64.rpm
