Hi all,
Hi, I need some help.
I have configured an instance with squid as a proxy service.
HTTP/HTTPS requests pass through the proxy correctly.
aclSafe_ports port9122
aclSSL_ports port9122
aclSafe_ports port22
aclSSL_ports port22
But I need to connect to an SFTP service that listens on port 9122.
On the squid configuration side I have added port 9122 to the secure
ports and the connection host to the hosts allowed in the dstdomain.
I have created the environment variables necessary to be able to exit
through the proxy:
http_proxy=http://myprox.prod:3142
ftp_proxy=http://myproxy.prod:3142
https_proxy=http://myproxy.prod:3142
Squid does not support this type of configuration. Each type of protocol
syntax needs to use a different proxy port number.
Current Squid versions also do not have working support for native
SFTP. For now you can only pass it through Squid if the client software
sends the SFTP traffic over a HTTP(S) CONNECT tunnel.
i try the connection but never happen

error:transaction-end-before-headers - HIER_NONE/- -
This is the expected outcome of a server-initiated protocol like FTP
being handled by a Squid listening port expecting client-initiated
protocol (HTTP or HTTPS).
