Nick Couchman commented on GUACAMOLE-2246:
------------------------------------------
Please capture the guacd logs and attach them - preferably in text format and
not a screenshot, and with guacd in debug mode.
> SSH connection failure to Cisco ASR-9902 Routers

> Key: GUACAMOLE-2246
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-2246
> Project: Guacamole
> Issue Type: Bug
> Affects Versions: 1.5.3, 1.6.0
> Reporter: Joel Widmer
> Priority: Major
> Attachments: guacamole_cisco_ARS9902_connection_logs-1.jpeg
>
>
> I'm using Guacamole to bridge network boundaries and expose SSH-based
> configuration endpoints for network devices. When attempting to connect to a
> Cisco ASR-9902 router, the connection fails. I'll attach a screenshot of the
> logs from the failed attempt below.
> My initial suspicion was a missing cypher, but after building and deploying
> commit 772a65a3334f7ded6d43cbe5e2ed347040a1fb52, I was able to rule that out
> (the cypher has been added since 1.6.0).
> I run guacamole on a RHEL server, using Podman to run the container images
> *Workaround*
> Connecting via SSH to an intermediate host and opening a session to the
> ASR-9902 from there works without issue.
> I'm happy to provide additional information or run further diagnostics to
> help narrow this down.
