RTC 4.0 zOS bfagent - problem connecting via port

 The RTC install on zOS for bfagent and buildtoolkit looked good and netstats shows that the port 5555 is available. The user has started up the bfagent under OMVS as a superuser and no errors when started.

Case 1 - from a command prompt on the users PC a "telnet hostame 5555" just times out - so we are thinking that may be a firewall related problem

Case 2 - from  TSO on the same LPAR that the bfagent is running on the user did a telnet to that LPAR with port 5555 (telnet ipaddress 5555) -  it got an error and could not connect to the port. No system console messages are seen.

case 3 - from TSO on a different LPAR than where the bfagent is running - the user did a telnet to the "bfagent" LPAR with port 5555 - we saw the standard "Helo" message and then it immediately terminated with the 210 message - Goodbye.

200 Hello - Buildforge Agent v7.1.3.0-0-0004

IBM Rational Build Forge Agent

210 GOODBYE - Rational Build Forge Agent


In both case 2 and 3 we get a bfagent log that appears to be normal up to a point - it does a bind and listen on port 5555 and creates a new agent and then gets an error

"IO io_gets: invalid char 0X18"


Any ideas and what the problem may be?
