[jira] [Created] (SSHD-782) Consider implementing a "reverse"
keep-alive mechanism in the server
Goldstein Lyor created SSHD-782:
-----------------------------------
Summary: Consider implementing a "reverse" keep-alive mechanism in the server
Key: SSHD-782
URL: https://issues.apache.org/jira/browse/SSHD-782
Project: MINA SSHD
Issue Type: Improvement
Affects Versions: 1.7.0
Reporter: Goldstein Lyor
Assignee: Goldstein Lyor
The current code contains only a keep-alive mechanism from clients to servers. We should consider implementing a "reverse" keep-alive mechanism from servers to clients using {{SSH_MSG_IGNORE}} messages. This mechanism should be along the lines of the {{ClientAliveInterval}} and {{ClientAliveCountMax}} parameters described in [sshd_config|https://linux.die.net/man/5/sshd_config], The mechanism can be used to avoid read timeout on the *client* side (e.g. SSHD-781)

The problem is distinguishing the difference between the keep alive traffic
and a long transfer. Either Mina needs a more advanced idle measurement or
SSHD would need its own idle manager.
