Aruna Potti commented on SSHD-869:
--
[~lgoldstein] Sorry I was not able to attach the screen shot. I was referring
about below keep-alive machanisms,
[https://github.com/apache/mina-sshd/blob/master/docs/client-setup.md]
* Sending {{SSH_MSG_IGNORE}} messages every once in a while.
This mechanism is along the lines of [PUTTY null packets
configuration|https://patrickmn.com/aside/how-to-keep-alive-ssh-sessions/]. It
generates small
[{{SSH_MSG_IGNORE}}|https://tools.ietf.org/html/rfc4253#section-11.2] messages.
The way to set this mechanism up is via the {{setSessionHeartbeat}} API.
_Note:_ the same effect can also be achieved by setting the relevant properties
documented in {{SessionHeartbeatController}}, but it is highly recommended to
use the API - unless one needs to control these properties *externally* via
{{-Dxxx}} JVM options.
* Sending {{keepalive@...}} [global
requests|https://tools.ietf.org/html/rfc4254#section-4].

-
I don't think so - please note the keep-alive heartbeat is only generated by
the SSHD *client* - I am not sure how {{ServerKeepAliveInterval}} behaves -
specifically what is the mechanism being used to keep the connection alive.

Goldstein Lyor commented on SSHD-869:
-
I am sorry that I cannot be more helpful - but like I said, 0.14 is an
extremely old version. BTW, even if you fix this issue, you will encounter many
more - so I really (really) encourage you to find some way to use 2.1.0. That
being said, the best I can offer right now is to look at the commit log of the
{{AbstractSignature}}, {{SignatureRSA}} and {{SignatureDSA}} classes and see if
you can figure out the patch. More specifically the usage of {{putBigInteger}},
the invocation of {{SignatureRSA/SignatureDSA#verify}}. In any case, please
note that IMO there is nothing you can do in your code to fix this - the
version 0.14 itself must be patched - so (again) better to upgrade to 2.1.0.

I need a fix/workaround in 0.14.0 version as I can not upgrade the version in
my product.

I am very sorry :(, but we cannot maintain several versions of the library due
to the extremely limited manpower we have. Furthermore 0.14.0 is an extremely
old version which contains many bugs that have been fixed since. I do strongly
recommend to make the effort and upgrade to 2.1 :) (unless you cannot use JDK
1.8 code, in which case I cannot offer a solution).
