Having trouble discovering any of our Dell PowerConnect 5524 or 5548. Just getting ssh_connection_error. Running v1.5.0 of Unimus. Switches are running v4.1.0.8 firmware.

Hi,

Could you please run Unimus in debug mode and run a discovery on the switch?
Please PM me the logs from the discovery attempt.

On Linux:

Code: Select all

sudo su
service unimus stop
cd /opt/unimus
java -jar Unimus.jar \
--logging.level.net.unimus.core=TRACE \
--unimus.core.echo-ssh=TRUE \
--unimus.core.echo-telnet=TRUE
On Windows:

Code: Select all

1) Download .jar distribution:
https://unimus.net/download.html
2) Stop Unimus service
If you are running the Portable version, skip this
3) Open an admin command prompt
4) change to folder where Unimus.jar was downloaded
5) Run "java -jar Unimus.jar --logging.level.net.unimus.core=TRACE --unimus.core.echo-ssh=TRUE --unimus.core.echo-telnet=TRUE"
6) Logs should be in the command prompt window
Thanks!

After investigation, we found these switches use a rather uncommon 1026 DH key, which we currently don't support.

In the short term, there is not much we can do about this.
In the long term, we are planning on updating our SSH client implementation around April/May, and we can fix this then.

I created a ticket on our Tracker which can be used to check on the progress:
