No SSH Response from Cisco SF350 (wodSSH / wodSSH.NET)

by Phill, Friday, May 29, 2020, 16:21 (1420 days ago)

Hi,

We are using the wodSSH.NET Component (2.6.4) against Cisco SF350 and have been unable to make a connection. Reviewing a wireshark trace we can see that the communication does not progress past the offered server and client protocols.

We are able to putty to the SF350 from the same server and so wondered if anyone had any recommendations?

Below is a text version of a wireshark trace.
10. is the SF350
192. is the system running wodSSH

No SSH Response from Cisco SF350

by Jasmine, Friday, May 29, 2020, 18:03 (1420 days ago) @ Phill

Hi Phill,

you seem to be using older version of wodSSH.NET, and I believe we did make fix for this 'waiting for other party' issue. Can you try with the latest if it works ok?

Regards,
Jasmine.

You made it so simple for us to integrate SFTP - a technology we had little experience with...

I would highly recommend this to anyone who needs a good quality SFTP solution.

Thank you very much for the rapid responses. I was a little nervous about dealing with a company that is on a different continent from me. You have proven my concerns to be unfounded.
