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. MVS TCP/IP TELNET CS V1R11 Connecting to ipaddress, port 5555 Using line mode... Telnet terminated -- No such connection (8543) 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. MVS TCP/IP TELNET CS V1R11 Connecting to ipaddress, port 5555 Using line mode... 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? |
One answer
Would you check the disable_telnet option in the bfagent.conf file? The option is used by default in the V4 z/OS bfagent while it was not in the previous releases. Although I do not fully understand what kind of problems the option could cause, it should change the behavior when the agent is interacted with a telnet client.
