[jira] [Commented] (SSHD-869) java.security.SignatureException:
error decoding signature bytes.
[ https://issues.apache.org/jira/browse/SSHD-869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16871856#comment-16871856 ]
Aruna Potti commented on SSHD-869:
----------------------------------
Hi Goldstein ,
If I enable OpenSSH related "ServerKeepAliveInterval"(SSH) on Linux and if
my apache mina based SSH client is running on this Linux box, can MINA
recognize those keepalives and disconnect mina socket/channel if these
keepalives fail and close the socket?
Thanks,
Aruna.
