I'm trying to use a socket over a SOCKS5 proxy setup using SSHTunnel. The socket connects to the Proxy without issue; ChilkatLog: Connect_Socket(1ms): DllDate: Dec 30 2015 ChilkatVersion: 22.214.171.124 UnlockPrefix: CISCOC Architecture: Little Endian; 64-bit Language: MAC OS X Python 2.* VerboseLogging: 1 objectId: 1 Component successfully unlocked using purchased unlock code. connectInner(1ms): hostname: 126.96.36.199 port: 22 tls: 0 maxWaitMs: 3000 socket2Connect(1ms): socks5Connect(1ms): SOCKS5: socksHostname: 127.0.0.1 socksPort: 1080 socksUsername: vuUoTU5nW9T>s. --SOCKS5 connectSocket: domainOrIpAddress: 127.0.0.1 port: 1080 connectTimeoutMs: 3000 connect_ipv6_or_ipv4: This is an IPV4 numeric address.

The connection to the host @188.8.131.52 failed but there is no indication in the error text or statuses until I shutdown the Proxy and view the accept log; ChilkatLog: sshOpenChannel: sshOpenChannel: Opening new SSH channel within SSH tunnel. sshTransportOpenChannel: channelType: direct-tcpip clientChannel: 100 clientInitialWindowSize: 327680 clientMaxPacketSize: 4096 directTcpHost: 184.108.40.206 directTcpPort: 22 originatorIP: 220.127.116.11 originatorPort: 62141 Sent open channel request Error reading channel response. --sshTransportOpenChannel Failed to open direct-tcpip channel failCode: 0 failReason: --sshOpenChannel --sshOpenChannel --ChilkatLog
In addition, closing the SSHTunnel proxy is taking the default 30 seconds to close which I assume might be the Socket Channel waiting to open on the non-responding device.
Any way to determine the status of the Socket's underlying channel after attempting to Connect?

There were some fixes relating to SSH tunnels in v18.104.22.168. I would recommend first testing that version to see where things stand..

Tried with the 22.214.171.124 version and still having issues.
The primary problem is the socket.Connect is succeeding in connecting to the proxy server but this is the only status available until the proxy is closed and the accept log is reviewed. The accept log then shows the SSHOpenChannel errors. There does not appear to be way to verify the success/failure of the SSHOpenChannel to the remote host in real-time. The process I'm working on is opening several socket connections to different remote hosts concurrently. The state of each socket to its remote host is needed.
