I have it partially working finally...the error information was kind of tricky as it said host key validation failed but that was not the problem....jsut adding StrictHostKeyChecking=no fixed the issue.
This bug report should be filed though...
What steps will reproduce the problem?
1. run pssh
2. It only says Command not specified and that is all unlike the documentation I read
What is the expected output? What do you see instead?
I expect it to print out all the different options like -o and -e that I found elsewhere through reading bug reports. It was pretty hard to get started and even now I still don't know how to have stdout from all machines just print to my screen without the -o option (like clusterIT did when I used that).
What version of the product are you using? On what operating system?
2.3.1
