Upgraded to OS 6.1, Shell not working

I had something like this happen once. In my case, java.exe also hung and drove up CPU. RDi 7.1 had the fix for the actual hang, however, my root cause with QShell not working was a firewall situation in our I/T area.

A Verify Connection operation <http://archive.midrange.com/wdsci-l/200803/msg00206.html#>, or trying to run STRRSESVR from your i5/OS command line might confirm if you have a firewall situation concerning server callbacks to the RSE daemon. When I authenticated to my firewall environment, then the QShell subsystem worked OK for me - there is a callback from i5/OS to the PC running WDSC involved
with the QShell subsystem/view.

In my case, when the TCP/IP
<http://archive.midrange.com/wdsci-l/200803/msg00206.html#> interface on i5/OS is restarted, I needed to re-authenticate with our firewall. The OS upgrade would have restarted your TCP/IP interface. It took a while to figure out what was going on in our environment, because QShell had worked before, and I couldn't figure out why it stopped working.

After upgrading to OS 6.1, the shell in WDSCi 7.0 doesn't seem to work. For instance, I usually compile java source from WDSC 7.0.0.8, but now the shell opens but none of the commands issued are processed. There isn't a prompt either. I think it used to be a> (in qshell through the green screen it's a $).

I'm wondering if maybe something isn't turned on.
