SSH connection to CISCO cannot be established - WeOnlyDo Discussion board

SSH connection to CISCO cannot be established (wodSSH / wodSSH.NET)

Hi *,

We have encountered problem using wodSSH.NET library together with CISCO switch.

Traces from CISCO cannot be obtained but from Wireshark I can see that CISCO does not responds to initial offer "Protocol (SSH-2.0-WeOnlyDo.Net)".

We have traces from other devices(and servers) and it is working, however I see that most SSH servers are unable to match the software version "weonlydo.net". Although they switch to compatibility mode and SSH connection is established.

CISCO switch SF350-24 with firmware version 7.3p1
wodSSH.NET version: 2.6.4.162

Traces from debian server (working SSH):
Nov 19 10:55:05 ENG-AUS-COR-408 sshd[19218]: Connection from 10.199.77.53 port 51207 on 10.199.77.5 port 22
Nov 19 10:55:05 ENG-AUS-COR-408 sshd[19218]: debug1: Client protocol version 2.0; client software version WeOnlyDo.Net

WeOnlyDo!COM will be the first stop I make should I require any further off-the-shelf components.

We have recently completed a large 1200+ location project where reliable Telnet and SSH connectivity was required. wodSSH worked flawlessly and allowed our staff to complete our project ontime and within budget.

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.

Just thought you'd like to know that my gateway app with your SMTP Server component held the line against a DDOS attack today...
