[jira] [Created] (SSHD-611) Servers rejecting keyboard-interactive authentication not handled
Oliver Stöneberg created SSHD-611:
-
Summary: Servers rejecting keyboard-interactive authentication not
handled
Key: SSHD-611
URL: https://issues.apache.org/jira/browse/SSHD-611
Project: MINA SSHD
Issue Type: Bug
Reporter: Oliver Stöneberg
I am trying to communicate with a server that advertises keyboard-interactive
authentication but it fails with "Too many authentication failures". When the
client sends the request it gets a failure and requests it again and again
until it hits the maximum retries value. It also never reaches the
UserInteraction object that was assigned to the client. It seems when the
request fails it should move on to the next authentication method.
Here's the output of sshd-core:

[jira] [Commented] (SSHD-474) Null pointer exception when connecting with latest Dropbear's dbclient

None of the current SSH clients use this option so we have not had to contend with it. I am testing some code that is designed to overcome this issue, and it does to the extent of getting over this bump. However, some other packets down the road after successful key establishment become corrupted (at least when using _DropBear_). We need a deeper understanding of what this means. > Null pointer exception when connecting with latest Dropbear's dbclient > -- > > Key: SSHD-474 > URL: https://issues.apache.org/jira/browse/SSHD-474 > Project: MINA SSHD > Issue Type: Bug >Affects Versions: 0.14.0 > Environment: Apache SSHD 0.14.0 binary distribution on a Redhat 6 > system.

[jira] [Updated] (SSHD-474) Null pointer exception when connecting with latest Dropbear's dbclient
[ https://issues.apache.org/jira/browse/SSHD-474?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Goldstein Lyor updated SSHD-474: Priority: Minor (was: Major) > Null pointer exception when connecting with latest Dropbear's dbclient > -- > > Key: SSHD-474 > URL: https://issues.apache.org/jira/browse/SSHD-474 > Project: MINA SSHD > Issue Type: Bug >Affects Versions: 0.14.0 > Environment: Apache SSHD 0.14.0 binary distribution on a Redhat 6 > system. Oracle Java 1.7.0_25. Dropbear 2015.67. >Reporter: Andrew Danforth >Priority: Minor > Attachments: dbclient.log, sshd.log > > > SSHD throws a null pointer exception when using dbclient from Dropbear > 2015.67 to connect. I believe this is due to dbclient attempting to reduce > message exchange during key negotiation. If you compile dbclient and comment > out #define USE_KEX_FIRST_FOLLOWS from sysoptions.h the session proceeds as > expected.
