ReferenceswolfSSL - Embedded SSL Library → wolfSSH → Problem Reconnecting to SSH Server - Clean Disconnection
Hello Everyone,
I am working on an ssh Server based on WolfSSH. Everytime I disconnect from the server ,I get the following debug messages.
When I try to reconnect to the server It becomes impossible and I should restart the system.
I am wondering if there is a method for clean Disconnection or any variables that should be initialized after disconnecting from the server.
Thank you.
Hello yass007
Thanks for contacting wolfSSL Support. Are you calling `wolfSSH_shutdown` before attempting the reconnect?

Hello Mr embhorn ,
Thank you for your quick reply.
I am getting little confused since I am working with server example project and not client project you sent.
https://github.com/wolfSSL/wolfssh/blob … ver.c#L263
In this file there is no use of 'wolfSSH_shutdown' but there is "wolfSSH_stream_exit'.
Can you please give me further explanation.
Thank you.
I don't recommend following the example server source. The echoserver is the example that works.
The WOLFSSH object isn't reusable right now. I preferred to create a new WOLFSSH for each incoming connection and free it when done. Servers tend to allow multiple clients to connect simultaneously, so the echoserver can create a new object per incoming connection.
The echoserver is calling wolfSSH_shutdown. wolfSSH_stream_exit would be closing one data channel in a session, not the whole connection.
