Firstly, I think SharpSSH is fantastic. Really clean interfaces and nice and quick.
I'm getting issues with the current version of Vmware ESXi which i believe is running on busybox. I'll post the full spec later when I get back from work.
Any SCP transfers are getting heavily corrupted - blocks of extra data are being inserted into the file at various offsets (zeros in the first block and non-zero subsequently).
ESXi is a free product if anybody can help out with diagnosis.
I'm happy to get involved in debugging it if anybody has any clues.
