Your authentication would be the SSL certs on both. The 'nc' command is reporting an error: 'unsupported proxy protocol'. Looking at the nc man page, your command syntax seems incorrect. The -X option (upper-case X) requires the name/number of a proxy protocol: 4 for SOCKSv4, 5 for SOCKSv5, and 'connect' for using a HTTP/HTTPS proxy. The proxy address and port are specified using another option: -x (lower-case x). The proxy port number 8080 suggests you're trying to use a HTTP or HTTPS proxy. So, please try this: sftp -o 'ProxyCommand /usr/bin/nc -X connect -x 10.105.54.134:8080%h%p' [email protected]. Driver paradox windows 10. Thanks MK for your reply! ![]() But still I am facing the issue. I am not sure whether it is SOCKSv4 or SOCKSv5, so I tried with both and same error. [root@test1 ~]# sftp -o 'ProxyCommand /usr/bin/nc -X SOCKSv5x 10.105.54.134:8080%h%p' [email protected] Connecting to files12.server.net. Nc: unsupported proxy protocol ssh_exchange_identification: Connection closed by remote host Couldn't read packet: Connection reset by peer [root@test1 ~]# sftp -o 'ProxyCommand /usr/bin/nc -X SOCKSv4 x 10.105.54.134:8080%h%p' Connecting to files12.server.net. Nc: unsupported proxy protocol ssh_exchange_identification: Connection closed by remote host Couldn't read packet: Connection reset by peer ================================================= How ever when I used like below it's hung.no message at all [root@erptest1 ~]# sftp -o 'ProxyCommand /usr/bin/nc -x 10.105.54.134:8080%h%p' [email protected] Connecting to files12.server.net. > Connecting to files12.server.net. > nc: Proxy error: 'HTTP/1.1 200 Connection established' > ssh_exchange_identification: Connection closed by remote host > Couldn't read packet: Connection reset by peer Looks like the proxy is a HTTP/HTTPS proxy, then. A SOCKS proxy would never answer with a HTTP protocol response. (It's still possible that the 10.105.54.134 server might also contain a SOCKS proxy, but if it's there, it's in some other port. The proxy software in port 8080 looks definitely like a HTTP/HTTPS proxy. The 'standard' proxy port number for a SOCKS proxy would be 1080.) The 'HTTP/1.1 200 Connection established' is not really an error: 'HTTP/1.1' is the protocol version, 200 is the HTTP status code meaning 'request was successful', and 'Connection established' is the expected message when opening a proxy connection using the HTTP CONNECT method. Maybe the nc command is displaying it as a 'proxy error' because the connection was suddenly broken from the remote end, and that was the only information nc received from the proxy? That would mean the connection from your sftp client to the proxy was successful and the proxy is trying to establish a connection to the files12.server.net server, but the files12.server.net server (or a firewall between the proxy and the files12.server.net server) is rejecting the connection. You might want to contact the administrator of that proxy server. Ask him/her if the proxy server has SOCKS proxy functionality too, and if it does, the correct proxy port number for that. Then ask him/her to try connecting from the proxy host to the files12.server.net host, like this: ssh -v [email protected] If the proxy server can talk to the files12.server.net server, the result will be a rather long list of diagnostic messages. Even if the connection is rejected because the files12.server.net allows only SFTP and nothing else, the diagnostic messages should indicate whether the basic SSH connection was successfully established before the rejection or not. If the proxy server does not have a SSH client installed, the 'telnet' command can also be used as a testing tool. If the basic network connection between the proxy and the files12.server.net is successful, the SSH/SFTP server at the other end will display its version identification, like this: $ telnet files12.server.net 22 Trying files12.server.net.
