Tectia SSH Server on z/OS mainframe

[mmaguigan]

I have seen this mentioned before in the issues, but when connecting to a Tectia SSH server on an IBM mainframe, this error immediately occurs at connection:

System.NotSupportedException: Data longer than 2147483647 is not supported.

I would be happy to investigate patching the issue myself if some initial guidance could be provided.

EDIT:

Stacktrace is below

Hi @mmaguigan, thanks for reporting. There was actually already a fix waiting to be merged, which we have done now. You can download the code in this repo and give it a try. Cheers

@Rob-Hague, thanks so much that's terrific. I just tested it out and can confirm that it resolved the connection issue and I was able to list the contents of a directory 😄
