Subject [jira] [Commented] (SSHD-346) "key_verify failed for server_host_key" Error
Date Wed, 01 Jul 2015 12:06:04 GMT

    [ https://issues.apache.org/jira/browse/SSHD-346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14610019#comment-14610019
] 

Goldstein Lyor commented on SSHD-346:
-------------------------------------

This may be a problem if the _hostkey.ser_ file is somehow deleted when the server is re-started.
In such cases, the server will generate a *new* set of keys, which will have a different fingerprint
- in which case (most) clients will reject it (at least when running in batch mode)

> Hi.
> We implemented the server using 'Apache MINA SSHD'.
> Function has been completed, we are testing performance.
> We call each 1000 'scp' command through a number command window.
> Then, the following error occurs intermittently.
> -----------------------------------------------------------
> key_verify failed for server_host_key
> lost connection
> -----------------------------------------------------------
> This occurs on both v0.11.0 and v0.12.0. 
> And v0.12.0 is occured more frequently.
> Gerrit also have the same problem, but i know that it fixed in a particular version.
> I'd appreciate it and tell you how to solve.
> Thank you
