-------------------------------------
Summary: Limiting the number of active sessions
Key: SSHD-1180
URL: https://issues.apache.org/jira/browse/SSHD-1180
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 2.6.0
Reporter: Subramaniajeeva
I upgraded mina version from 2.3.0 to 2.6.0 two months back. Since then I
could see that the number of sessions being held keep on increasing for a
particular client. I found this using
{color:#9876aa}sshd{color}.getActiveSessions().
On analysing further,I could see the below messages from debug logs:
{code:java}
2021-06-05 00:00:00.222 [DEBUG]
[sshd-SshServer[18a79bc1](port=2000)-nio2-thread-5] ServerConnectionService -
globalRequest(ServerConnectionService[ServerSessionImpl[<username>@/10.125.247.40:46011]])
received SSH_MSG_GLOBAL_REQUEST [email protected] want-reply=true{code}
Looks like the client keep on sending keep alive packets even after the file
transfer is done keeping the session active. I didn't see this behaviour in
earlier version.
Can I get some help on resolving this issue? Is there a systemic way to figure
out the last activity based on which cancel the session?
